This plan has come from the efforts and directions of the Planning Commission, the Board of Trustees and interested citizens . The general land use plan for the Town of Erie and its fringe area has evolved from basic land use patterns now existing , development projections of land owners , physio- graphic and geologic factors , and special consideration for various public services . Through modification and analysis , these factors have been integrated into a Compre- hensive Plan to reflect in broad terms considerations for the future growth and development of the Town and its surrounding environs . The Erie Comprehensive Plan analyzes , encourages , antici- pates and guides basic uses of land in the Erie planning area into planned workable relationships by determining and identifying integrated land utilization. Only broad recommen- dations for the future use of all land in the planning area are proposed. The plan attempts to balance the many land use requirements of the present and future population for housing, business , industry, parks , open spaces , recreation, community facilities , public utilities , transportation and traffic facilities . Environmental considerations are recognized and have been taken into account . The environmental concerns are protection of water resources and their flow ways , preservation of natural vegetation, prevention of erosion on steeper slopes and avoidance of areas affected by past underground mining operations or by floods . 1 -1 Concepts and patterns of the Erie Comprehensive Plan reflect the awareness of the Town as being the center _ physically , socially and economically of an area much larger than the existing Town boundaries indicate . The plan illustrates this fact by establishing the basis for efficient area wide planning and administration. Implementation of the plan will clearly strengthen and more adequately define the functions to be performed by the core community for a comprehensively organized urban area. This planning document is a first step toward comprehen- sive town planning and as such, attempts to establish a framework for effective and coordinated area-wide growth. As elements of this framework , town goals and objectives will determine policy and direction for short - and long-range developmental plans for all aspects of the Town' s resources . Planning itself is a goal . Usually one or more objectives must be attained to reach a goal . Planning is , therefore , concerned with allocation of resources to permit attainment of the individual objectives necessary for progress towards the final goal . It is intended that this Comprehensive Plan capture and define all major factors and realities needed for future planning efforts of the Town of Erie. 1 . 2 Objectives The fringe area of Erie, Colorado , has and is experiencing growth. Whether portions of the fringe area become incor- porated into the Town or not , these areas will be part of the total community. The residents of the Town of Erie have the choice of either allowing the fringe area to develop into an - uncoordinated urban sprawl which will destroy the ultimate character of the community or of providing for the planned orderly development of the Erie area through comprehensive planning and the service area concept . 1- 2 Part of the area surrounding Erie , although presently of a rural nature, will within the next few decades assume an urban character. It is essential , therefore , that the Comprehensive Plan recognize the potential change in character of the Town and the influences which will cause these changes . Thus , the general purpose of this Comprehensive Plan for the Town of Erie is to develop and analyze current data about the Town and translate these analyses into a general long-range guide for growth , which fully interprets the potential for development of the community from its physical , social and economic standpoints . By the adoption of a Comprehensive Plan for the Town of Erie , the Planning Commission and Board of Trustees have established goals and objectives which are, in their estimation, items of the highest priority in the planned orderly develop- ment of the Town and its surrounding environs . The objectives of the Erie planning program are as follows : 1 . To serve as a technical aid and guide for the Town so that the continuing problems of a changing economy, population, environ- ment and physical structure may be dealt -- with knowingly and constructively. 2 . To create a pattern of development which will be efficient and practical and which will control the waste of land caused by inappropriate occupancy. 3. To integrate future development with an overall traffic circulation system which will link not only the existing Town circulation plan, but also existing and proposed County , State and Federal road systems . Such integration of a traffic circulation system shall provide for 1- 3 appropriate rights -of-way with adequate widths prior to the encroachment on such areas by development . 4 . To preserve adequate open space and recreational areas throughout the sphere of influence of the Town for the use of present and future residents of the Community . S . To establish development standards relating to the subdivision of land and construction of streets and utilities so that future maintenance costs will be held to a minimum and so that such improvements will not become a financial burden upon the existing Community . 6 . To develop and implement a plan for the procure- - ment of an adequate water supply to satisfy the needs of the area included in this Comprehensive Plan . 7 . To prepare and adopt Ordinances which will protect land values within the present corporate limits of the Community as well as in areas which may be annexed in the future. Such Ordinances shall provide for an environ- ment of development which will encourage reasonable and controlled growth within the sphere of influence of the Town of Erie on a pay-as-you-go basis . These Ordinances shall also provide for the preservation of the public health, safety , and welfare by limiting development to those areas which do not exhibit geologic , hydrologic , or environmental problems . 8 . To provide for the long range development of _ wastewater collection and treatment facilities for the service area and the existing Town 1-4 which will satisfy the more stringent water quality standards required by State and Federal guidelines . Such facilities , where practicable , shall consider wastewater collection and treat- ment of effluent from other portions of the Coal Creek basin not included in this Comprehensive Plan in order to provide regional pollution control . 9 . To acquire , for the benefit of the residents of the area , those tracts of land as may be appropriate for such public uses as parks , additional school sites , fire stations , police stations , libraries or other public uses which , in the opinion of the Town Board , may be appropriate . 10 . To serve as a guide for the consolidation of special service districts , private service areas , and other agencies in order to minimize the duplication of administrative and capital improvement costs related to the public services provided by these agencies , both public and private . 11 . To establish the core area as the focal point of the Community in regard to civic , cultural and social functions . 12 . To establish a continuing policy of review of land use proposals so that needed adjust- ments may be made as changes in the character of Erie occur . 13 . To initiate a program of landscaping and rehabilitation of the core area . 14 . To establish a firm policy of review for continuous upgrading of public improvements requirements . 1 - S 1S . To establish a firm policy of referrals and advisory relationships between the Erie Planning Commission, the Boulder and Weld Counties ' Planning Commissions and all other local public or semi-public bodies and extend these relationships to the regional and State levels as may be appropriate . 16 . To adopt a firm policy of review and updating of this Comprehensive Plan in order to insure that the objectives of this plan are being satisfied. 17 . To establish a firm policy for the dissemination of information to the public by all available means including encouragement of active participation by citizens ' committees . 1 . 3 Policies The policy of guided growth as officially adopted by the Planning Commission and the Board of Trustees of the Town of Erie upon the formal acceptance of this Comprehensive Plan, will encourage growth but will require that the financial burden of such growth be borne by the future developments in the area . Such growth shall be viewed by the Erie Planning Commission and the Board of Trustees in the light of its economic impact on the Community, environmental considerations and quality and style of occurrence. The Erie Planning Commission under the direction of the Board of Trustees assumes the responsibility of coordinating activities and programs of the various agencies with juris- _ diction throughout the Erie service area. Active and continued participation in the planning processes of separate and distinct agencies is considered an important function in the implementa- tion of the Erie Comprehensive Plan. 1-6 By adoption of this Comprehensive Plan and related implementing Ordinances , the Town of Erie hereby establishes its support to the concept that future growth should be in close coordination with existing urban areas within Weld and Boulder Counties . Erie planning activities in the Town ' s area of influence will also seek to recognize the planning activities and programs of Boulder and Weld Counties and of nearby incorporated jurisdictions or special districts . Where feasible , planned unit developments will be encouraged to raise the quality and prestige of development activity throughout the Town' s area of influence . A balanced pattern of residential development will be encouraged in and around the Town to provide housing for all age and income groups and efforts will be made to reduce or improve conditions of blight and deterioration . Strip development along existing or proposed arterial roads will not be considered in the best interests of the Community. Commercial and industrial development will be permitted in accordance with this plan only when such development encourages an orderly land use pattern, a safe and functional traffic circulation design, and satisfies all reasonable aesthetic considerations . The Town of Erie will continue to develop within its present boundaries and additional utility facilities will be required to serve these needs . Whether these facilities can be provided at the lowest possible cost to the Town' s existing residents depends on the acceptance and implementation of the service area concept . By offering to provide water and/or sewer services to outside Town customers only upon those customers' willingness to agree to several stringent conditions , the Board of Trustees of the Town of Erie seeks to achieve : 1 . Planned orderly development of the Town and its fringe areas , and 1- 7 2 . A sound equitable financial structure for the municipal utilities . The service area concept involves : 1 . The determination of that geographic area surrounding the Town of Erie in which the Town will consider providing water and/or sewer service to outside Town customers , and 2 . The establishment of terms and conditions to which outside customers must agree in order to receive either or both of these services . These terms and conditions shall include but not be limited to review of development plans by the Town of Erie , conformance with this Com- prehensive Plan and conformance with all utility extension policies , annexation policies and construction standards which are now in effect or which may be in effect in the future . 1-8 SECTION 2 - PHYSIOGRAPHIC CHARACTERISTICS 2 . 1 Location and Climate The Town of Erie is located in Southwestern Weld County and eastern Boulder County in Section 18 , Township 1 North , Range 69 West of the 6th Principal Meridian and in Sections 13 and 24 , Township 1 North, Range 69 West of the 6th P .M . The community presently consists of approximately 1 , 067 acres . Erie is divided by the north-south line of Boulder and Weld Counties resulting in 818 acres of the town being located in Boulder County and 249 acres being located in Weld County . The community is situated approximately ten miles east of the City of Boulder and approximately two miles south- east of the confluence of Coal Creek and Boulder Creek. Climatic data reveals that the Erie area has an average yearly precipitation of about 16 inches , and that temperatures vary from - 20°F in January to 100°F in July with a mean annual temperature of 50 . 8°F . The average growing season is approxi- mately 163 days . 2 . 2 Topography The Erie Planning area is part of the Rocky Mountain Front Range region and exhibits rolling terrain substantially without exposed rock outcrops . Elevations vary from 4 , 950 feet in the northernmost portion of the planning area to 5 , 310 feet southeast of Erie . Those areas to the southwest and northwest of Erie , gently slope toward the confluence of Boulder and Coal Creeks . Southeast of Erie the land slopes gently to the east of the Community Ditch and displays rugged and rolling slopes toward the west . Consequently , the area between the Community Ditch and Coal Creek is severely dissected and is undesirable 2-1 for farming or extensive development . The area to the north- east of Erie is similar to the gentle slopes southwest of town . The entire area is traversed by many natural and man-made drainage courses . The areas to the southwest and northwest of Erie contain several lakes , ponds and reservoirs with Panama No . 1 Reservoir being the largest body of water in the region . There are small areas of marsh lands along the creeks , ditches , and lakes . Although the area is traversed by many large and small bodies of water and drainage courses , there are few wooded areas . 2 . 3 Soils Plate No . 1 illustrates the distribution of various soil associations in the Erie Planning area . In general , the soils found in the Erie area are the result of decomposition of the underlying sandstone and shale bedrock, or are an expression of aeolian or fluvial deposits . Five major soil associations have been recognized and are classified as follows : 1 . Fluvaquents - Fluvents association 2 . Weld-Adena-Colby association 3 . Samsil-Shingle association 4 . Platner-Ulm-Renohill association S . Ascalon-Olney-Vona association The Fluvaquents - Fluvents association is typically located in the floodplain of Boulder Creek, where surface slopes vary from 0 to 3 percent . Characteristically, bedrock in this locale is found at depths greater than 40 inches . This soil association is commonly located in areas of flood hazard. Those areas exhibiting the occurrence of this soil association are severely limited in the use of septic systems as a means of domestic sewage disposal . 2-2 The Weld-Adena-Colby association is primarily located on upland plains where slopes vary from 0 to 3 percent . This association attains thickness in excess of 60 inches . Per- meability of this soil is moderate to slow and serves as a fair road fill material . In general , this soil association does not occur where flood hazards exist . The use of septic systems as a means of domestic sewage disposal is only moderately limited in areas where this soil profile exists . The Samsil-Shingle association is composed of a relatively shallow, moderately drained clay- loam soil . This soil profile is found on steeper hillsides exhibiting slopes of 9 to 25 per- cent . Bedrock is typically less than 20 inches below the sur- face . Generally, this soil association represents slow to moderate permeability and severely limits the use of individual septic systems . The Platner-Ulm-Renohill association consists of a moderate to well drained clay loam. The Platner component is generally found on slopes of 0 to 3 percent while the Ulm and Renohill components may occur on slopes as steep as 15 percent . The subsoil profile of the Platner and Ulm components is moderately to strongly developed , attaining a thickness in excess of 60 inches . Depths of 20 to 40 inches are more typical for the Renohill . In general, the occurrence of this soil profile represents moderate to severe limitations on the use of individual septic systems . Most extensive of all soil occurrences in the Erie planning area is the Ascalon-Olney-Vona association. This soil profile consists of deep, well drained, sandy loam which attains thicknesses in excess of 60 inches . Typically this association occurs where slopes vary from 3 to 9 percent and generally where no flood hazard exists . The use of individual septic systems is only slightly limited where this soil profile occurs . Of all the soils found in the Erie area this association is most susceptible to wind erosion . 2-3 v Cr' T - C N C — c O = c O m av` m m._ CL w 3 vi } m m 3 N 3 m -c •0 Q'o ^n v c v 0 �.. m- �.. v m `" 3 v ^a) m fl. o Q Z E Es o v vrn - v E > 6 11 U0 CL n s v v- E o v 3v Eo N 3T - L3 vN ^o v 37 o (n > c.ioo 3T EN OUP C • J Ou av = v= - 0 0 Q o o Up rn 3 y Q° � N o Z O 3N � v O (1)-c5 W (n me � c Um -SCI a W H O•o Q v O N -1'CI co Q v, W Na mm Cno Oa>'o Oo \\ Q J W >"co Jai Q.

In order of decreasing age these are ; the Fox Hills formation, a relatively thin beach deposit of tan sandstone associated with a few thin shales , and the Laramie formation, a thick sequence of sandstones , shales and coal beds . Fox Hills sandstones are light tan to brown colored , strongly cross -bedded and highly iron stained . The formation is fine grained in the lower portion and exhibits varying grain size in the upper parts . On the basis of field examina- tion and comparison of drill logs the formation thickness appears to average approximately 80 feet immediately to the west of the Erie planning area where outcrops are accessible . The Laramie formation is a thick series of sandstones and shales which is divisible into two parts on the basis of dominant lithologic type . The upper division consists almost entirely of shales with some thin beds of sandstone and lignite . The lower division is mainly composed of sandstones separated by beds of sandy , carbonaceous shales and interbedded coals . Sandstones of the Laramie formation are white to tan colored , even-bedded, and frequently exhibit a polygonal pattern on weathered surfaces . The over-all range of grain size is large , but individual beds are well sorted . Most of the upper portion of the Laramie is absent from the area as a result of faulting and erosion, but at other locations the upper division of the Laramie attains thicknesses of 400 to 600 feet . Where complete sections have been observed the total thickness of the formation varies from 600 to 1200 feet . The Denver Basin and the Front Range Anticline dominate regional structures . The anticline is a long narrow fold whose axis trends approximately north from Canon City , Colorado , to the vicinity of Laramie , Wyoming . The Denver Basin is immediately 2-5 east of and parallel to the Front Range Anticline . A system of dip slip faults which repeat and omit Upper Cretaceous sediments of the Fox Hills and Laramie formations dominates the local area. The fault system consists of a major set of north- east-trending strike faults which is a part of a series that extends northeast from near the mouth of Coal Creek Canyon to a point on the South Platte River in the vicinity of Platteville . Dip slip movement of the fault blocks has caused horsts and grabens with accompanying repetition and omission of beds between the faults . Where the Laramie has been exploited for coal the mine workings have been contained within fault blocks where the coal has not been removed by erosion. Where movement has resulted in a horst or upthrown block the mined areas may be near the surface . An adjacent downthrown block or graben may contain coal mine areas at considerably greater depth. Typically , mined areas in adjacent fault blocks are not interconnected due to the large vertical displacement of the faults . The groundwater potential of both the Fox Hills and Laramie formations is extremely limited. Moderate quantities of water are obtained from wells drilled into the Fox Hills . Water quality is generally acceptable for domestic use except in areas of faulting where water derived from the Fox Hills may have undesirable levels of iron or hardness . Typical yields range from 10 to 25 gallons per minute with some water wells attaining production levels of 100 gallons per minute . Water yields from the Laramie lithology are extremely limited . When flows are obtained from the Laramie the water quality is poor , exhibiting hydrogen sulfide , iron, and methane contamination from the coal seams associated with the formation. Where the Fox Hills is overlain by the Laramie formation proper casing and cementation procedures must be employed to prevent contami- nation of the higher quality Fox Hills water by the less desirable water from the Laramie . 2 -6 In areas which have been mined for coal the abandoned workings have filled with groundwater . Water from such under- ground "reservoirs" is of doubtful value when considered as a domestic or municipal water supply . Extremely high levels of dissolved solids , sulfate , iron and arsenic dictate that expensive and sophisticated treatment be employed to produce water of acceptable quality for domestic and municipal use . Large quantities of shallow groundwater do exist in alluvial gravel deposits contained within the flood plain of Boulder Creek in the northwest portion of the planning area . These waters could be exploited by the Town of Erie as a potential water supply only if adjudicated surface water could be supplied to the stream in an augmentation plan approved by the State Engineer . The lack of ownership of adequate long range surface water storage by the Town and the lack of poten- tial reservoir sites in or near the planning area suggest that the Town of Erie investigate the use of the alluvial gravels in Boulder Creek as a part of its long range water development program. Such a plan could alleviate the need for large and expensive surface water storage in the future . 2 . 5 Drainage Boulder Creek and Coal Creek, tributaries to the South Platte River Basin , are the major drainage courses in the Erie planning area . The confluence of these two creeks is located approximately two miles north of the Town. Since the location and extent of flood plains are important factors in the deter- mination of land use allocations , both Boulder and Coal Creeks were studied for the Intermediate Regional Flood (IMF) . The IMF represents a flood with an average frequency of occurrence of approximately once in one hundred years . This so-called "100 year flood" is a minimum standard for the application of local regulations and flood protection. 2-7 That portion of Boulder Creek upstream of North 95th Street was previously studied by the U .S. Army Corps of Engineers . The flood flow data contained in the Corps ' study was used to extend the limits of the flood plain from 95th Street to a point two miles north of the northern limit of the region under consideration . This extension of the flood plain limits was based on stream and valley conditions shown on the latest topographic maps available and is only a reasonable estimate , rather than a precise determination , of the probable occurrences . The IMF developed by the Corps ' study was 11 , 000 cfs . below the confluence of Boulder Creek and South Boulder Creek. This flood creates a flood plain with an average width of about 2 , 500 feet . The flood plain widens to about 3 , 000 feet as Boulder Creek receives the additional flood discharge from Coal Creek . Although exact flood data for the Coal Creek drainage is sparse the Soil Conservation Service does have limited informa- tion relative to historic floods on Coal Creek. According to the SCS the most significant floods on Coal Creek are : 1876 13 , 200 cfs . (at Erie) 1921 7 , 800 cfs . (at Erie) 1938 3 , 500 cfs . (at Erie) 1969 3 , 400 cfs . (at Superior) A basin analysis of Coal Creek reveals that the Inter- mediate Regional Flood for this stream at Erie is approximately 8 , 330 cfs . This flow was used to delineate the flood plain of Coal Creek from Baseline Road downstream to its confluence with Boulder Creek . Except for the section where Coal Creek has been channelized within the Town of Erie , the flood plain definition is only a preliminary estimate based on topographic maps . South of Erie the Coal Creek flood plain widens to 1 , 000 feet . This indicates that the 100 year flood channel work 2-8 recently accomplished within the Town should be extended to the properties south of the existing Town limits before such land is approved for development . Constrictions downstream from the recent channel improvements in Erie still present a potential flood hazard to the Town. Some efforts are being made by both Boulder and Weld Counties to remove and alleviate these constrictions . These efforts , although commendable , are not extensive enough to provide complete 100 year flood protection to the Town. In the future the Town of Erie should require property owners north of the community to con- struct necessary channel improvements on their property as a requirement to receiving utility service or as a condition of annexation. The Intermediate Regional Flood areas for both Coal Creek and Boulder Creek are illustrated on Plate 2 . Both flood plains have been integrated into the land use plan as open space. It is strongly recommended that these areas be maintained as perpetual open space for recreational purposes and that no permanent structures be permitted within the IMF area of either stream. 2-9 0 0 0 CI M W O o z I— O 2 z II cr W V w o N Z Q Z _ O• n (n d5 a w z Q W w015 a z wo = —CC CCz o � I- w O w i = Q Z Q W o Q o -- - - . - �- i - W J Z 1 \ 1 J LL I ll CL 0 \ \ ` , Z -�� 0 N - N *� ��� 1 J LL. • /7 )_ A -= \� )' � G _ �/ - 1 I II �_. �� k�1jv• �,_._ `� 1 \ \''c s.✓, \ \fir-----� of I \ `'_ __ _. \,._1- -1 ---- 0 - € v1 - II i a ��- 77 1 � x �; A y ! r i \,_ I , _ _ A i / I �� j I / / I \4.____ L. ,t / ,/..--- --,. ,, I 7 , , T i _ �� ���� ,_ y, 1.

Plate No . 2 indicates the probable extent of these mined areas as derived from original underground mine maps , drill hole information and shaft data. Although this exhibit has been prepared from the best available data and from informa- tion believed reliable , anyone using this exhibit must be cautioned that areas not indicated on the plate may be under- mined by cross cuts and exploratory drifts that were never recorded. The Erie land use plan incorporates undermined areas as open space where insufficient cover exists to support structures . Room and pillar extraction methods were used to _ remove the coal and large void areas were created . Development of the surface areas near known workings should be preceded by a detailed examination of the mine and drill hole records and the land surface on an acre by acre basis . Those areas with known workings having inadequate rock cover should be exempted as development sites and the overlying land in these areas should be used for golf courses , parking lots , parks , and recreational areas . Prior to development the area will undoubtedly be photographed and contour maps prepared by photogrammetric techniques . Such photos should assist in delineating areas of surface subsidence connected with the mined areas . Those areas designated as open space on the land use plan where undermining occurs have been selected on the basis of conservative analysis . It is recommended that reduction _ of the outer limits of such areas be considered only after detailed subsurface information supporting the modification is provided to the Town of Erie for evaluation. In Section 13 , T1N, R69W seven coal mines are known to exist . Typically these workings are 90 to 120 feet below the surface and were used to exploit a coal seam ranging in thickness 2- 11 from 51/2 to 62 feet . The workings include those of the Brennan, New Crescent , Star, Jackson, Long ' s Peak, Northrop and Chase mines . Approximately 160 acres of land are affected by these mines in Section 13 . Eight mines occur in Section 24 , T1N , R69W. In general , the workings of these mines are situated 45 to 94 feet below the surface and exploited a 4 to 5 foot thick coal seam. The workings in this area include those of the Tynon, Stewart , Lister , Garfield No . 1 , Marfell , Pinnacle , McGregor and Cleve- land mines and affect about 150 acres of land in this section. Upper and lower seams were exploited in the Stewart , Garfield No . 1 , Pinnacle and McGregor mines . Workings of the Clayton, State and Columbine mines are known to exist in Sections 17 , 20 , and 29 , T1N , R68W, involving approxi- mately 300 , 500 , and 430 acres respectively . The majority of these workings are less than 250 feet below the surface and involve coal seams varying from 41/2 to 7 feet in thickness . In _ selected areas the amount of cover above the workings or the limited extent of the workings is considered adequate to support low density development . Where such is not the case the areas exploited by these mines have been designated as open space . The only extensive mine workings known to exist in Section 18 , T1N, R68W are associated with the McGregor mine and involve approximately 65 acres in the southeast portion of the section . Two seams were exploited by this mine and the upper workings are within 45 feet of the surface . In Section 19 , T1N, R68W five coal mines are known to exist . Typically these workings are 90 to 118 feet below the surface and were used to exploit two coal seams , each ranging in thickness from 4 to 5 feet . The workings include those of the Briggs , Garfield No . 2 , Lloyd, Mitchell No . 2 and the Lehigh mines and affect approximately 175 acres of land in this section. 2-12 The only known workings located in Section 31 , T1N , R68W are associated with the Parkdale mine and effect approxi- mately 135 acres . Less than 150 feet of cover exists over these workings . 2-13 SECTION 3 POLITICAL CONSIDERATIONS 3 . 1 History of Erie The first settlement of the Erie area by patent took place in 1871 . Throughout the history of the Eric area ranching and coal mining have played an important part in the economics of the region . Substantial areas around the present Town of Erie were homesteaded by prominent early settlers in the Boulder and Coal Creek basins . The Town of Erie was originally incorporated in 1874 instituting a Mayor-Council form of Government . The population of Erie has varied considerably throughout its history depending on the economic status of the mining and ranching industries to which it is closely related. Between 1864 and 1880 there were approximately 300 permanent residents in the Community. Gradually the population rose to approximately 1 , 000 residents and from 1930 to the present has varied between 874 and 1 , 090 persons . In recent years Erie has materially increased the land area contained within its corporate limits by annexation of property adjacent to the south and west boundaries of the Community and by annexation of property adjacent to the eastern Town limits . No development activity has taken place in the area annexed to the west and south of the original corporate limits . The area to the east of Town extending from Coal Creek to the right-of-way of the Union Pacific Rail- road on the east is in the process of site preparation for use as an industrial park for light industrial use . 3 . 2 Erie Town Government The Town of Erie is administered by a Mayor-Council form of Government consisting of a Mayor and six Trustees . The Mayor is elected for a two year term and the terms of service - for the Trustees are split equally between two and four year 3-1 terms . Generally , the Board of Trustees meet in regular session on the first and third Mondays of each month. In accordance with Colorado Statutes the Town has established a Planning Commission which consists of seven appointed members . The Planning Commission reviews and makes recommenda- tions to the Board of Trustees and the Mayor in regard to building , zoning , subdivision and other land use matters . The Board of Trustees administers the general business of the Town and operates the Town water utility through a sub- committee. Municipal sanitary sewer facilities are administered by the Board of Directors of the Erie Water and Sanitation District , a quasi Municipal Corporation established under the Special District Statutes in the State of Colorado. The administrative Board of the Sanitation District consist of a President and four Directors with regularly scheduled meetings occurring the second Monday of each month. 3 . 3 Boulder and Weld Counties Until recently the incorporated area of Erie was located entirely in Weld County. Annexations to the west have resulted in extension of the incorporated area of the Town into Boulder County. Historically, neither Boulder nor Weld County officials have expressed active interest or expended much effort on improvements in this isolated area of their respective counties . To a great extent this lack of interest has been due to the low economic base of the Erie area , lack of initiative by local public officials and isolated geographic location in regard to the mainstream of development in the respective counties . This division of the Erie planning area by the Boulder- - Weld County line creates many administrative problems for local government . Separate and distinct planning and subdivision 3- 2 regulations are applied to different portions of the planning area. Different tax assessments are applied to the property within the Erie planning area and separate administrative procedures are involved in the review processes involving development depending upon the county involved. Planning regions established by the State of Colorado tend to follow county lines and Erie is in two separate regional planning areas . Boulder County is a member of the Denver Regional Council of Governments whereas Weld County is a member of the Larimer-Weld County Regional Planning Commission. Both areas are presently within the Regional Transportation District but Weld County is attempting to remove itself from this entity. Growth characteristics of these two counties have been quite different over the past twenty years . Population in Boulder County has tripled since 1950 , primarily due to the impact of I . B.M. and satellite industries associated with this concern. During the same period, the population of Weld County has increased by only one-third. The plains area in Boulder County has undergone substantial urbanization whereas Weld County has and is maintaining a rural emphasis . The Town of Erie has tended to be caught between the somewhat different philosophies of these two county governments . Implementation of the Erie Comprehensive Plan requires close coordination between Erie and the Boulder and Weld Counties ' officials . For such plan to be effective both counties must _ be willing to coalesce their respective regulations and attitudes applicable to the Erie planning area into meaningful support of both the Erie Comprehensive Plan and the desires of local government . 3. 4 Northern Colorado Water Conservancy District That portion of Erie situated in Weld County is not presently within the Northern Colorado Water Conservancy 3- 3 District . This prevents Erie from obtaining Big Thompson water for direct use , storage or trade . Erie is ideally situated downstream from the Boulder Supply Canal which delivers Big Thompson water to Boulder Creek. The Board of Directors of the District have become less and less inclined in recent years to accept new areas into the District . It is recom- mended that Erie attempt to be included into the Northern Colorado Water Conservancy District at the earliest possible date . Plate 3 illustrates the present boundaries of the Northern Colorado Water Conservancy District and those areas which the District will consider for inclusion for domestic water service . Since a substantial portion of the Erie planning area is within the District it is essential to the implementation of the Erie Comprehensive Plan that the boundaries be re-aligned to include all the planning area within the Northern Colorado Water Conservancy District . The general policy of the Board of Directors of the Northern Colorado Water Conservancy District has been to require a new area to pay all back taxes of the District since 1937 , including interest . This amount is determined by calculating the annual tax assessment that would have been paid each year since 1937 on the annual assessed valuation of the property to be included . Based on an average annual assessed valuation of $500 ,000 the total tax assessment for inclusion would be approximately $15 , 000 . Colorado-Big Thompson water is the most stable source of water supply in northeastern Colorado . The short and long term benefits to the Erie area of being included in the Northern Colorado Water Conservancy District cannot be overemphasized. _ Such inclusion permits Erie to be extremely flexible in future water development plans . 3-4 The Colorado-Big Thompson is operated by the Bureau of Reclamation to provide supplemental water to water users in Northeastern Colorado and consequently the water allotments as determined by the Northern Colorado Water Conservancy District are dependent on both the availability of and need for Project water . Availability is dependent on water supply conditions in the area of the Project ' s western slope collection system. The need for Colorado-Big T water is measured by weather and water supply conditions in Northeastern Colorado . Colorado-Big T water rights and water deliveries are measured in terms of acre-foot units . There are a total of 310 , 000 acre-foot units of Project water and consequently the holder of one acre-foot unit is entitled to one-three hundred ten thousandth (1/310 , 000) of the total Project deliveries in a given year . It is the practice of the Northern Colorado Water Con- servancy District to declare on the first Friday in April the percentage allotment of Project water to be delivered during the coming irrigation season. If weather and water supply conditions warrant , a supplemental allotment is declared in June or July. The water yield to a holder of Colorado-Big T water is directly related to the percentage allotment. Thus in a year having a 60 percent allotment , the holder of 100 acre foot units of Colorado-Big T would be entitled to 60 percent of 100 acre-feet , or 60 acre feet . Colorado Big T percentage allotments for the years 1957 through 1972 are summarized in the following tabulation. 3-5 Initial Supplemental Total Allotment Allotment Allotment Year (%) (%) (%) 1957 60 0 60 1958 100 0 100 1959 80 0 80 1960 60 10 70 1961 60 0 60 1962 60 15 75 1963 70 30 100 1964 70 20 90 1965 60 0 60 1966 70 30 100 1967 70 0 70 1968 60 0 60 1969 70 0 70 1970 60 0 60 1971 60 0 60 1972 70 10 80 *Information obtained from the Northern Colorado Water Conservancy District TABLE 1 COLORADO-BIG THOMPSON WATER ALLOTMENTS 1957-1972* On the basis of historical allotments , it can be seen that the firm annual yield of an acre- foot unit of Colorado- Big T water should be taken as no more than 0 . 6 acre-feet . Although some Big T water is utilized for domestic pur- poses by municipalities and water districts , the project is normally operated only during the irrigation season of April through October. According to the Northern Colorado Water Conservancy District the most recent firm sales of Big Thompson water have been at the rate of $260 per unit . On this basis the present value of an acre foot of water as compared to a pro- ration of the Big Thompson allotments would be as follows : dry year $260/ . 6 = $434 . 00 per acre foot average year $260/ . 77 = $338 . 00 per acre foot wet year $260/1 . 00 = $260 . 00 per acre foot 3-6 U) U zL) _ >.. � Cr m w 8 2 CI) Z Jz o z ICI — moo 11 U � cro of rn c:c > o ``- w W w ( U` o > i z QdS z o • W x � uwi o w • w �? � � � . t., Cr Z CC cnp I- w w o in z w � NMIk �€�L�l Q W w a aooa LL J J 0 I— Z O �, • • J Z � � it O • �3 , *II W F...

Domestic water service from Left Hand to a development requires that the development pay certain membership fees and provide specific facilities . In general , one membership in the Left Hand Water Supply Company is considered the equivalent of one single family residence. An applicant for service from Left Hand must pay a $1 , 000 membership fee for each single family equivalent . In addition, one unit of Big Thompson water is required for each membership. Such uses as mobile homes consist of four mobile homes per membership , for fee calculation purposes . Where no water mains presently exist , an applicant for service must construct the necessary line extension at his expense. Where water mains are already in place the appli- cant for service must pay a frontage fee based on the lineal footage of water main adjacent to the applicant ' s property. The cost of all internal distribution lines and other necessary appurtenances such as storage and pumping stations must be borne by the applicant requiring the service. Typically, residential developments are served by means of a master meter. Residential service charges of the Left Hand Water Supply Company are as follows : Minimum fee of $12 . 00 per month for up to 5 , 000 gal . Additional fee of 70O1 , 000 for usage between 5 , 000 and 10 , 000 gal . Additional fee of 60O1 , 000 for usage between 10 , 000 and 20 , 000 gal . Additional fee of 30O 1 ,000 for usage over 20 ,000 gal . 3- 8 The Brownsville Water and Sanitation District is the only other water distribution entity in the Erie planning area. This entity was formed under the enabling statutes of the State of Colorado for Special Service Districts and encompasses approximately 300 acres due west of Erie in the area of the Brownsville subdivision. The land presently included in the District contains 285 residential lots upon which 150 homes have been constructed. Management of the District anticipates attaining total development in the District within three years . Two 550 foot water wells provide the source of water for the District system. Application has been made by the District for permission to install two additional wells . The distribution system of the District operates from a 100 , 000 gallon storage reservoir and provides an average static pressure of 55 psi . It is represented by management that the District is in excellent financial condition. At this time the District has a $30 , 000 cash surplus and additional bonding capacity of $390 ,000. Revenues are received by the District from connection fees and use revenue. Average monthly residential water use in the District is approximately 10 , 000 gallons . Present fees and charges for service from the District are as follows : Connection Fee $500 plus cost of installation Monthly Charges $12 . 50 min. fee for first 10 , 000 gal . Additional fee of . 454/1 ,000 for usage in excess of 10 , 000 gallons per month. In June , July and August the monthly charges are $12 . 50 min. fee for the first 15 ,000 gallons with an additional fee of . 354/1 , 000 for usage in excess of 15 , 000 gallons . 3-9 Although the District was originally formed as a water and sanitation district , no central sewer system has been installed. All residential dwellings within the District employ individual septic systems as a means of domestic sewage disposal . No firm plans presently exist for installing public sanitary sewer in the Brownsville Water and Sanitation District but management indicates that the District anticipates such an installation within five years , using 75% Federal financing . 3-10 SECTION 4 - PUBLIC FACILITIES AND SERVICES 4 . 1 Transportation Plate No . 4 illustrates the location of major roads and railroads in the Erie planning area. This exhibit classifies the major vehicular corridors into three major categories - Interstate highways , State highways and County roads . The main rail lines of the Union Pacific Railway and Chicago , Burlington and Quincy Railway are also indicated. Interstate Highway 25 , with a right-of-way width of approximately 300 feet is the most traveled road within the region. Interstate 25 is a limited access highway with only three interchanges at three mile intervals along its length through the region. These interchanges are located at the intersections of I- 25 and Baseline Road , Weld County Road No . 8 and State Highway 52 . State Highway 52 , with a right-of-way width of 120 feet , is coincident with the northern limit of the planning area and is the second major road in the region. Highway 52 provides excellent east-west circulation and easy access to the I . B.M. facilities located approximately mid-way between Boulder and Longmont . State Highway 287 , with a variable right-of-way width of 60 to 140 feet , provides secondary north-south circulation between the northern Front Range communities of Fort Collins , Loveland, Longmont , Lafayette , and Broomfield. This State highway is coincident with the western boundary of the Erie planning area. Baseline Road or State Highway 7 , with a 60 foot right-of-way in Boulder County and a 75 foot right-of.-way at the Adams-Weld County Line , coincides with the extreme southern boundary of the Erie planning area. This road in 4- 1 comparison to other major highways in the region is not suited to high speed travel and is generally not used by long distance commuters . The bulk of the traffic on Baseline Road is generated by developments situated adjacent to its right-of-way between Boulder and Lafayette. The rights-of-way of the above mentioned highway and of the rights -of-way of several other minor county roads are used by many utility companies for the extension of utility facilities . Except for certain electric and telephone lines all utility lines are buried in highway rights-of-way adjacent to and outside of the traveled road surface. The approximate locations of these utility lines and other related information are shown on other exhibits elsewhere in this comprehensive plan. 4- 2 0 0 ,C F3 } Q o W " Crl- >- CC a z Z - = - = < z _ cn o o O 0 w-- z- - Z CC f o o 2 UJ O W o w a Q I- W 0 W a CC J H I Ii.

The portion of the planning area in and around the Town of Erie and in Boulder County falls within the service area of the Public Service Company of Colorado . That portion of the planning area in Weld County east of the existing corporate limits of Erie is serviced by the Union Rural Electric Associa- tion of Brighton, Colorado . The locations of service area boundaries and transmission facilities for both electric com- panies are illustrated on Plate 5 . The Town of Erie has a franchise agreement with the Public Service Company of Colorado for electric service . A boundary settlement agreement established approximately ten years ago between the Public Service Company of Colorado and the Union Rural Electric Association provides that the lines are to be sold to Public Service and electric service relinquished by REA when an area receiving electric service from REA is annexed to the Town. Extension policies of the REA provide that service exten- sions for a permanent use are installed at the expense of REA. Where an extension of electric service is made to any other use that is not permanent , the user is required to pay 650 of the installation cost . This investment by the user is refunded if and when permanency of use has been established . Tabulated below are the present residential and small commercial rates for electric service from REA: Rural Residential Rates 50 kwh - 10¢ for each kwh with a minimum of $5 . 00 a month Next 50 kwh - 4a¢ for each kwh Next 900 kwh - 1 3/4¢ for each kwh Over 1000 kwh - 1 . 3¢ for each kwh Small Commercial Single Phase 100 kwh - 8¢ for each kwh with a minimum of $8 . 00 a month Next 900 kwh - 1 3/4¢ for each kwh Over 1000 kwh - 1 . 3¢ for each kwh 4-4 Cr) w W Z X I. a _z J 0 Z Z O Z Z o � Z � � m Y in p a •� CO .-. o m ds • Q - fY z CO W i cc c) M W - p i d p i Q W W w vp wcc d w � J c� \ Z W Cn O io a J L- —, a s a t �� i Et Z � � °.�� ll 0 �"' N . � N !II a om as • I1 r - - � , t: \„, iI, , �� . iI , (✓ li �,i 1'' — .1 .�' ..1 - � A, t° , ' i , I o " ► r s:;� ��t yti \ I a 1, .. annual -- — _I __ _F____________ �I IK -mac �� i J a lid 1 - — Z 1 / \?

Plan A is applicable to overhead powerline extensions where the use of the service is to be perma- nent and where a continuous return to the company of sufficient revenue to support the necessary investment is assured in a rural area . Sufficient revenue is determined to be 11% of the cost of the total investment required for the service extension . This amount must be received as revenue each month or in the case of seasonal service must exceed 18% per year. If revenue percentages cannot be met then a Revenue Guarantee Contract must be entered into by the applicant and Public Service . In this contract the applicant agrees to pay to the Public Service Com- pany, on a continuing basis , the amount of revenue required to support the Company' s investment . In general terms the Company will not invest money for line extensions without a guaranteed return. Plan B has been prepared in which Public Service asks an applicant with indefinite service requirements to underwrite a necessary line extension by advancing to Public Service , prior to construction of the extension, a refundable construction deposit . The Company will then refund, without interest , a portion or all of the construction deposit during the five year period immediately following the opening date of a given line extension . The portion refunded will amount to 20% of the annual revenues received for service from the line extension. Monthly charges for general residential service are based on the following tariff as approved by The Colorado Public Utilities Commission. First 20 kilowatt hours or less used $ 1 25 Next 60 kilowatt hours used , per kwh . 043 Next 920 kilowatt hours used, per kwh . 025 All over 1 , 000 kilowatt hours used, per kwh 015 MONTHLY MINIMUM 1 25 4-6 Electric rates for residential underground service are somewhat higher as indicated in the following tabulation . First 20 kilowatt hours or less used $ 1 . 90 Next 60 kilowatt hours used, per kwh . 053 Next 920 kilowatt hours used, per kwh . 027 All over 1 , 000 kilowatt hours used, per kwh . 015 MONTHLY MINIMUM $ 1 . 90 Tariff revisions for Public Service Company are presently under consideration by the Public Utilities Commission of the State of Colorado and the above described rates may be increased in the near future . 4. 3 Natural Gas Natural gas is available to only a limited portion of the Erie planning area at this time . The locations of existing natural gas facilities are illustrated on Plate 6. In general , line extensions are made at the expense of the Public Service Company when demand for natural gas in an area is sufficient to justify the extension. Residential service is provided in the Erie area under the following tariff as approved by the Public Utilities Commission . First 400 cubic feet or less used $ 1 . 26 Next 1 , 600 cubic feet used, per 100 cubic feet . . 11242 Next 6 , 000 cubic feet used, per 100 cubic feet . . 05742 Next 6 , 000 cubic feet used, per 100 cubic feet . . 05042 Next 6 , 000 cubic feet used, per 100 cubic feet . . 04842 All over 20 ,000 cubic feet used, per 100 cubic feet . . 04642 MONTHLY MINIMUM $ 1 . 26 4-7 y- _z H w � I— J _z W cn z o —' Z U z Z _ U O co J > W C9 I7 ds D ct m o Cr Z Q W Cr CC Cr) Ili Cr z 0 Y ro QJ w w = .�— J Q w LIJ Q v - , a Ct U.

Plate 7 illustrates the locations of telephone lines and exchange boundaries . As can be seen from this exhibit the great majority of the telephone lines in this region are under- ground except for the original incorporated area of the Town of Erie. It is recommended that Erie further the concept of undergrounding by requiring this type of installation in its subdivision regulations . As improvements are made within the core area efforts should be made to underground the existing overhead lines within the town. 4-9 W CD UJ Q > ' J z S _ I. . 0 w J R U Z Z Z c Q O w c X U s T z w x w o ti W �' w w a co• C � Ct w Q w z a w oz Q ~ W _ � Z Z Cr z � o = in _ Q — w w J CO w — : . — -- --' ._J J = w w > > - �� � s_ � w m � � I-- O m l' �, Z Q _ q ! \� x �, I, o z _ m „ �� 3 Nk ‘1Slint,' a 1 N W o - ► l 1C J W j ` � .� 1- 4 • ._�_ L�.. / X11 ..i � - �'\ \ i i 4'\N. ,45IIIIIM,AMPra d /II �____ co ------'\..C/ 1 �.� o �� _ ) \ �:J mom;_ �� , : , I \ 1 ��.� — --� --) - a ' �� l ^' w l)' i i' \ 2 l I o; / 1 � � ( / i - 9, IIII /-- � w ) i, �� / �\ � 1--- / ,_,4. t a i - \_, 7 / 1\ / _ T �/ / - �r i� � _ - -r -\ ✓... -- �.,,: 1 \ ti \ i /' � � - -\,. _. --_._ / '�1 / - _ 1\ ..vim° .. . «-- �_ ® f \ ,- r� f� ' _ , / 1 _.?__•_,_.,...- ICI✓_ M69 8 fit. , � , / _ � . v .. / p' '.,,,o4, 13381S 3Ni/- AiNnoo is"�-.. / c� ` - f , / L� —=s 1�\ N ) J "..=)____i v (' 1 —a -�� ——"i ,�' n v� L. f '_== == - 1 ' ___ _: ,. n �, <,� _ N I 4 . 5 Water Erie is not within the area considered by the Metro Water Study prepared in 1969 by the Denver Regional Council of Governments . As stated in the DRCOG report "Erie is not within the boundaries of the integrated plans contained". . . in the study. The general context of the DRCOG study and its predecessor study the Metropolitan Water Study, May , 1965 , by the Inter-County Regional Planning Commission indicates that the Erie area is presently too far from major population centers to be considered a part of any regional water development plan. Although several integrated plans are suggested for other communities in the DRCOG Study, none includes the Erie area as a viable and contributing community. This attitude implies that , although it is on the border of the Denver Metropolitan Statistical Area, Erie and its surrounding area must devise and implement its own water resource and distribution facilities plan. Present water rights of the Town of Erie consist of 120 shares of a total of 610 shares outstanding in the South Boulder Canyon Ditch Company. This ditch owns adjudicated rights in South Boulder Creek comprised of: Priority #21 , dated May 15 , 1870 , adjudicated for 26 . 37 cfs . Priority #24, dated May 15 , 1871 , adjudicated for 59. 63 cfs . Subsequently 20 cfs were abandoned. The effective total of these decrees provides for 66 . 0 cfs . In a preliminary planning study dated July, 1968 , and prepared by Nelson, Haley , Patterson $ Quirk, Greeley , Colorado , it was assumed that Erie could receive 1 , 545 acre feet of water, less ditch losses with sixty days ditch flow at full decree. Examination of the historic diversions 4-11 made by the South Boulder Canyon Ditch Company indicates that the yield per share has been substantially less than the theoretical legal amount allowed. Table 2 illustrates typical yields of the South Boulder Canyon Ditch. Headgate Yield/Year to Erie Yield/Share Based on 120 Shares 33 year average (1936 to 1968) 4 . 2 Ac. Ft . 504 Ac .

TABLE 2 HISTORIC YIELDS OF SOUTH BOULDER CANYON DITCH As can be seen from Table 2 , the annual yield that Erie can expect from the South Boulder Canyon Ditch is 320 acre feet . The zero yield in 1954 dictates that Erie must have carryover storage capability and rights of sufficient seniority for such dry periods . In addition to the ditch yields , Erie owns the Erie Reservoir and Prince Lake No. 1 . These storage rights provide the following storage capacity. Erie Reservoir 264 . 40 acre feet Prince Lake No. 1 90. 32 acre feet Total storage 354 . 72 acre feet 4-12 The need by Erie to acquire water rights of sufficient seniority is emphasized by the following tabulation of reservoir performance during the period 1953 to 1956 inclusive.

TABLE 3 ERIE 6 PRINCE RESERVOIR NO. 1 STORAGE HISTORY Therefore, present annual water capability of rights held by Erie amounts to: South Boulder Canyon Ditch 320 . 00 acre feet Storage 354. 72 acre feet _ 674 . 72 acre feet This assumes carryover storage capability to preclude zero flows in dry years and is not adjusted for ditch and reservoir loss . Table 4 indicates the yield of these water rights when adjusted for ditch and reservoir loss . 4- 13 South Boulder Canyon Ditch (Loss calculated @ 250) 240. 0 acre feet Erie $ Prince Lakes (65 acre feet loss to evaporation) 289. 7 acre feet Adjusted Annual Yield to Erie 529 . 7 acre feet TABLE 4 ADJUSTED WATER RIGHTS YIELDS FOR ERIE Historically, Erie has experienced continuing water supply problems . Several attempts have been made by the town to acquire additional water rights to augment its present supply. Recent improvements have been made to the raw water storage, treatment plant and treated water storage facilities of the Town. These improvements were designed - in order for the water utility to properly serve a population of 1, 350 . In addition, individual water meters were installed throughout the community in 1972 . The present population served by the water utility is 1 , 090 with a typical household containing 3 . 22 persons . Therefore , the Erie water system can only accommodate approximately 80 additional residential dwellings before extensive expansion of water source and storage facilities will be required. The water treatment plant will accommodate in excess of 3 , 000 population if sufficient finished water reservoir space is available to accept the production of the plant during periods of low demand. It is abundantly clear that in order to accommodate even limited growth Erie must begin an immediate and aggressive program of water rights acquisition. An essential ingredient to such a program will be the establishment of rules whereby new subdivision developments are required to dedicate to the Town water rights of sufficient priority such that the rights will yield approximately 1 . 5 times the water required for the new subdivision. This concept should be incorporated in the Erie subdivision regulations . 4 -14 Under a policy of this type the Town should increase its raw water inventory over a period of time and eventually have a reasonable water right reserve. As previously stated, inclusion into the Northern Colorado Water Conservancy District is also an essential requirement if Erie is to adequately solve its raw water inventory problems . In addition to the above described steps the Town must establish a program of water rights acquisition of its own by the option and purchase of any available direct flow rights which may become available in the area and which are of suitable priority for use or trade. Table 5 provides a tabulation of ditches , either incorporated or unincorporated, in which, on the basis of historic yield or storage capability, Erie should attempt to gain an interest .

The City of Broomfield has obtained treated water from Denver via a large diameter water line extension which has brought high quality Denver water to a point approximately five miles due south of the Erie planning area. Erie could attempt , by contractual agreement with Denver and/or Broomfield, to obtain treated water from this Denver line . It is recommended that Erie at least open discussions relative to this long range solution to its water needs . Broomfield still owns the Great Western Reservoir even though the City has consumated its agreement with Denver. Erie should include the future disposition of Great Western in any discussions with Broomfield. Great Western would not only solve storage needs but also provide much of the long-term water required by Erie and its surrounding area. Assuming Erie could acquire this facility , a minimum of 3 , 200 acre feet of storage water would be available . In addition to the above described potential water sources consideration should be given to the Coal Creek Project . The Coal Creek Project was proposed in 1962 by the Louisville Planning Commission. A reconnaisance study was made in 1969 by Kenneth L. Bruns & Associates , Inc. of Longmont. Briefly the project is to provide : 1 . Supplemental irrigation water 2 . Flood control 3. Domestic water storage 4 . Recreation S . Industrial Waters 6 . Land management practices A review of the Bruns report , examination of existing water claims in the Coal Creek basin and examination of historic stream flows indicates that the Coal Creek drainage is already over appropriated. Any apparent surplus water is entirely claimed by storage rights senior to any claim made 4- 16 at this time by the Coal Creek Association. Although reservoir sites are available on Coal Creek, these sites would only be of value to store: 1 . Ditch rights converted to storage 2 . Foreign water imported from outside the basin. The Bruns report offers the following suggested approaches to the Coal Creek Association. 1 . Approach A - water users in the basin maintain a status quo and attempt to develop their own water supplies to meet their future requirements . 2 . Approach B-1 - this assumes that the :association is successful in obtaining raw water from Denver. 3. Approach B-2 - this assumes that the association is successful in obtaining a master meter contract with Denver . 4 . Approach C - this assumes the Association is successful in obtaining water from the Northern Colorado Conservancy District . S . Approach D - relates only to the development of a sanitary sewage collection and disposal system. 6 . Approach E - assumes that the Association negotiates a working relationship with the Farmers Reservoir & Irrigation Company. 7 . Approach F - assumes the Association forms a conservancy district to serve raw water. 8 . Approach G - assumes the Association develops a water service system using water rights in South Boulder Creek. 4-17 9 . Approach H - relates to the development of the Coal Creek Basin for flood protection , storage and water acquisition. This also assumes full development of the basin in a long range plan including area wide sanitary sewage collection and disposal . At this time it appears that the Coal Creek project is too indefinite and such benefits as may be derived are too long term to be useful to Erie Continued involvement in the project by Erie can only result in on-going costs assessed against the community with no immediate benefits . Erie is at the point where its own water resources must be expanded and improved now. An expanding community should have sufficient direct flow rights to allow a reserve for future growth. In order for a town to operate entirely on direct flow, both its rights to withdraw water from the stream and the available flow in the stream must be adequate to meet demands at all times . Practically speaking , there are times when stream flows are insufficient to meet municipal demands , and even with the most senior rights on a stream , it would be necessary to supplement direct flow with a certain amount of storage . With adequate reservoirs to carry over storage from year to year it is possible to provide a greater amount of water during low water years than is naturally available from run-off. To make water trades , conditions on the stream must be such that (a) a demand exists under a senior downstream right , (b) water must be available at the point the town desires to divert the water , and (c) no other appropriator is damaged. Trading water during wet years under these conditions is easy, but during dry years when the need is greatest , trading is difficult . 4- 18 It appears that satisfactory acquisition and management of a long term water supply for Erie and any large development in the Erie area requires the integration of additional raw water reservoir capacity in the water acquisition program. Within this framework the Coal Creek Project can be beneficial to Erie. As previously discussed consideration should also be given to the development of water sources in the alluvial gravels of Boulder Creek. Present charges for in-town residential water service from the Erie Water Utility are as follows : Minimum fee of $6. 50 per month for up to 3 , 000 gal . Additional charge of $1 . 00/1 , 000 for usage between 3 , 000 and 6 , 000 gal . _ Additional charge of 80*/1 , 000 for usage over 6 , 000 gal . In addition to the above described fees an additional surcharge of $3.00 per month is assessed against each water user to assist in the payment of debt incurred in the recent expansion of the water treatment plant . During the months of December and January flat fees are assessed for water service in lieu of reading individual meters . For this period the in-town and out-of-town residential rates are $6 . 50 and $11 . 00 per month respectively, not including the surcharge . Commercial water rates are indicated below : Minimum fee of $6 . 50 per month for up to 3 , 000 gal . Additional charge of $2 . 00/1 , 000 per month for usage between 3 , 000 and 6 , 000 gal. Additional charge of $1 . 20/1 , 000 per month of usage over 6 , 000 gal . 4-19 4 . 6 Sanitary Sewer The present Erie Water and Sanitation District sanitary sewer facilities consist of a sewage collection system and two oxidation ponds for treatment. Essentially, the system serves only the Town of Erie and all the developed area within the Town is servicable by the system. Financially the District is in excellent condition. Outstanding debt amounts to $21 , 000 which is to be retired in equal annual payments over the next three years . In general , the sanitation system has experienced a low maintenance and repair history. Present treatment capacity is adequate for a population of about 1 ,600 and the sewer outfall line from the Town to the oxidation ponds is adequate for a population of 2 , 000 . Existing charges made by the District are extremely low. Connection fees amount to $150 for a single family residence and service charges have been established at $7 per quarter. In view of the potential growth in the area additional treatment facilities will undoubtedly be required for Erie to adequately provide sanitary sewer service in the future . Fees for new connections and service charges should be increased now to permit the accumulation of cash reserves to expedite such improvements when they are required. The present charges for sanitary sewer service in Erie are not proportionate to the service being supplied. Sewer Service charges should be raised to a level approximately equal to the charges for domestic water use . In addition, connection fees for new taps should be raised to an amount at least equal to the water connection fees or higher. The actual fees to be charged in the future should be adequate to enable the community to expand the sanitation utility on a pay- as-you-go basis . 4- 20 Any major sewage treatment plant expansion should not take place at the site of the existing oxidation ponds . Future treatment facilities should be constructed in the general area of the confluence of Boulder and Coal Creeks so that the facilities can serve the entire Erie planning area. Site selection should also take into consideration sufficient land area to ultimately accommodate a regional sewage treatment plant able to serve the majority of the Coal Creek Basin. At present , the Erie Water and Sanitation District is governed by a Board of Directors which is separate and distinct from the Board of Trustees of the Town. The operation of the Town utility systems by two separate boards tend to create misunderstandings , multiplicity of effort , duplication of costs and in certain circumstances can be divisive in nature . Centralized administration of both the water and sewer systems would allow: (a) Simplified procedures in negotiating with developers and other applicants for service . (b) Reduction in overall operation costs by unified billing and more efficient use of operational personnel and equipment . (c) Development of consistent rules and policies . (d) Easier control over customers who are in default on accounts . For example , if the sewer billing is unpaid, the water can be turned off. 4- 21 (e) Unified use of surpluses from both utility revenues for other municipal purposes . (f) Easier expansion of the systems under a utility master plan. In view of the above, it is recommended that the Board of Trustees open discussions with the District concerning the ultimate takeover by the Trustees of the operation of the sewer system, combining the sewer and water operations under a utility department within the administrative control of the Town Board. 4- 22 4 . 7 Fire, Police and Schools Fire protection in Erie is provided by the Erie Volunteer Fire Department consisting of 26 volunteer members of the community. The department owns one pump truck of 1970 vintage and operates from a fire station located at Wells Briggs Streets . Law enforcement in the Town is provided by a municipal police department composed of two full time patrolmen, six reserve officers , one dispatcher and a secretary. Department facilities include a jail with one active cell . Erie is situated within the St . Vrain Valley School District RE- 1J . The elementary school provides facilities for kindergarten through grade 6 and has a present enrollment of 554 pupils . Facilities include 20 classrooms with a design capacity of 600 students . Faculty and staff consists of 34 teachers and 14 administrative and service personnel . The Erie Junior-Senior High School has a design capacity of 650 students , with present enrollment approximately 481 . The existing school sites are presently adequate but certain expansion capabilities are limited . Combined - Junior-Senior high school operations can be maintained for a period of time. Ultimately , however, these operations should be separated and an independent site should be reserved elsewhere in the community for the installation of a senior high school facility. It is recommended that this new school site be located in the undeveloped portion of the Town located in Boulder County. The elementary school site is of adequate size and no changes are recommended for it . 4- 23 SECTION 5 - SOCIO-ECONOMIC CHARACTERISTICS 5 . 1 Economy and Population Erie is located in an area where the economy has been closely related to agricultural and mining pursuits . Since mining activities have declined in recent years , many Erie residents commute to Denver , Boulder, Loveland and Longment for employment . At the present time, Erie has no identifiable industrial base of its own. A great opportunity for the growth of Erie lies in the provision of suburban homes for employees in the industrial areas of the previously mentioned cities . Less than thirty minutes of driving time separates the larger cities from the uncongested living conditions in Erie. The latest available total assessed valuation of the Town, according to the offices of the Boulder and Weld County Assessors , is $602 , 500 for 1972 . Properties in Erie are subject to a total levy of 141 . 40 mills , 37. 0 mills of which provide revenue for the Town ' s General Fund. The following tabulation indicates the specific allocation of the 1972 tax levy in the Town. County 20 . 40 mills School District 77 . 65 Town General Fund 37 . 00 Sanitation District 6 . 00 RTD 0 . 35 Total 1972 levy 141 . 40 mills At present the Town of Erie has bonds outstanding in the principal amount of $421 , 000 . Of this debt $416 , 000 represents debt incurred in 1972 for water system improvements and $5 , 000 represents residual debt incurred in previous water system improvements . This residual debt is scheduled for payment in December, 1973 . 5-1 Detailed economic characteristics of the present population of Erie were not available for inclusion in this Comprehensive Plan at the time of preparation. The assumption is made , however , that Erie, with its historic ties to Weld County, is closely allied with Weld County in terms of income , age distribution and educational levels of its population. Table 6 is provided herein to indicate what may be considered the general income characteristics of the Erie area.

The past history of the community is that of a small Colorado farming and mining town and the future growth can not be a logical extension of past experience . This is mainly due to the anticipated expansion in the developmental activities of the region which are not related to mining and farming operations . Table 8 compiled from data provided by the United States Bureau of Census indicates the historic population figures for the Town of Erie . Year Population 1890 662 1900 697 1910 596 1920 697 1930 930 1940 1 ,019 1950 937 1960 875 1970 1 , 090 TABLE 8 PAST POPULATION PROGRESSION OF ERIE 5- 5 The anticipated growth of a community in the Front Range of Colorado is a function of two factors . First , the Front Range of Colorado is projected to assume the bulk of the future development in Colorado . Already this pattern of development has affected major cities in the region and considerable development in and around small towns has taken place . Second, it is projected that the rate of further development around large towns will decrease in the coming years while smaller towns such as Erie will assume a larger portion of the future growth in the region. This concept has acquired momentum in the recent past and many new developments in and adjacent to smaller towns in the region are already underway. In Erie, the anticipated growth is also a function of other resources such as the availability of desirable land, the availability of an adequate circulation network , the availability of a comprehensive land use plan to control growth , the availability of public services , and finally the willingness of public officials and private investors to take the steps necessary to make Erie a desirable place to live and work . Figure 3 illustrates two population projections for the Town of Erie. Curve A is a straightline projection based upon historical population data. Such a projection is a dangerous guide to growth in a very small town such as Erie. It is easily seen that a population increase of a few hundred persons would be insignificant in a major metropolitan area , but it would have a tremendous affect in Erie. Many single incidents could create such a "population explosion" . The advent of one relatively small industry, or the upgrading of the Town to attract suburbanites , could initiate such growth. Interviews with land owners and developers in the Erie area indicate such an "explosion" is imminent .

Even using such adjustments it is projected that Erie ' s population could increase by 300% or quadruple its present population of 1 , 090 persons during the next five years . Curve B , Figure 3 indicates the projected population of Erie based on these factors . This projection takes into consideration only those anticipated developments already within the existing town limits or development of land contiguous to Erie ' s corporate limits which are expected to annex to the town in the course of their development . Additional growth within the total planning area is anticipated but is not contiguous with the present town limits and these projects are not expected to be annexed to Erie in the near future . Furthermore , these growth projections do not take into consideration all of the possible development which could occur in the area contiguous with the town since some developers have resisted disclosing their plans until such time as their financial contracts are finalized. Possible population impacts resulting from total development of the Erie Planning Area are discussed in Sections 6 and 7 of this report . As mentioned earlier Curve B Projections are based on developers ' estimates , adjusted downward to eliminate over optimistic projections . It is possible that favorable financial conditions and favorable market demand may accelerate the development process and a higher growth level will be attained. It is also conceivable that Erie could experience S-8 negative growth as a result of protest to deteriorating facilities and services . Such a process could well be detrimental to the existence of the Town. Substantial loss in tax base or possible loss or reduction of available services , such as the Erie Bank , further encourages an outward migration and eventually will affect the Town ' s chances for survival in future years . The dilemma facing local government in Erie :is obvious . Excessive uncontrolled growth will place disasterous burdens on existing public works and the Town treasury. No growth or negative growth could seriously jeopardize the ability of Erie to function as a viable community. It seems clear that local government must take the essential steps necessary to accommodate reasonable growth within the policies and philosophy of this Comprehensive Plan. Capital improvement programs related to water sources , sewage collection and treatment , paving and drainage must be implemented as soon as possible and maintained on a continuing basis to assure Erie ' s future as a viable community in the Front Range area. Rules and regulations requiring the highest possible development standards and compelling growth to be self-supporting must be instituted and rigidly enforced to assure the existing residents of the community that the potential growth envisioned by this growth analysis will not detrimentally alter the quality of life in Erie . 5 . 2 Housing Analysis An inventory of existing structures was conducted to determine the existing conditions , types and locations of all residences and to outline housing characteristics within the Town of Erie. Each building within the incorporated 5-9 area was rated in one of three categories based on criteria used by the Federal. Bureau of the Census and the Department of Housing and Urban Development . The categories and the differentiating criteria are as follows : a. Sound - An apparently sound or adequate building which , because of its age (post-1950) and apparent care, most probably is in no need of corrective action. b. Deteriorating - A deteriorating building displaying correctable deficiencies or a building that is expected to contain systems deficiencies which are in need of corrective action. c . Dilapidated - A building which is extremely deteriorated and obviously substandard to a degree requiring clearance. To complete the list of all residential quarters available in the community , the location and number of all mobile homes were also noted without reference to their condition. It was concluded that most mobile homes were built within the past few years and therefore should be in fair condition. Furthermore, due to the mobility of mobile homes , upgrading by replacement can occur in a short period of time , thereby periodically altering the statistics on the physical condition of mobile homes and housing in general . Table 9 provides an inventory of the condition of all housing units in Erie. Table 10 illustrates the number of houses and mobile homes and the relative percentage of each. Several conclusions can be drawn from 5-10 these tables . The over-all percentage of dilapidated houses in Erie in quite low. Although the economic base of Erie has deteriorated over the last two decades , its proximity to Denver, Boulder , Longmont , Greeley and other large urban centers has given the local residents the incentive to take better care of their homes . Second, the number of mobile homes is substantial , providing moderate to low-cost shelter for families moving to Erie . The inclusion of mobile homes in the sound housing category has greatly reduced the impact of deteriorated and dilapidated housing on the analysis . The analysis therefore indicates a somewhat better and more promising housing situation than actually exists in the town . Three-quarters of the blocks in the Town of Erie exhibit some deteriorated and dilapidated housing . The most trouble-free housing areas appear to be located north and south of the high school , and to a lesser degree in the east and northeast portion of the community. The areas to the south and north of the high school are in particularly good condition, and the statistics here are not distorted by the presence of mobile homes . Most of the "problem" housing areas appear to be affected by environmental deficiencies . The southern portion of the town , which has the highest amount of problem housing, is almost completely surrounded by railroad lines and other undesirable factors such as vacant barns , dilapidated structures and junkyards . This area is also deficient in park and play areas and in the quality of the streets and sidewalks . 5-11 Housing Condition Number of Houses Percent of Total Sound 141 47 . 80 Deteriorating 124 42 . 04 Dilapidated 30 10 . 16 Total 295 100 . 00 TABLE 9 HOUSING BY CONDITION IN ERIE Housing Type Number of Houses Percent of Total Mobile Homes 70 19 . 18 Conventional Structures 295 80 , 82 Total 365 100 . 00 TABLE 10 HOUSING BY TYPE IN ERIE 5-12 An inventory of housing outside of the Town of Erie , but within the Erie planning area , reveals the existence of 298 residential structures . Of this total , 291 structures were found to be convential residential dwelling units and 7 were found to be mobile homes . Essentially no dilapidated dwelling units were identified in this inventory , testifying to the relative youthfulness of the structures . S-13 SECTION 6 LAND USE ERIE SERVICE AREA 6 . 1 Existing Land Use The pattern of existing land use has the strongest kind of influence on development of long-range plans . Through a study of the nature of existing land use , its conflicts and trends , a basis is usually established for the formulation of the planning recommendations . The assets and liabilities of the existing land use pattern must be determined if objective judgments are to be made during the planning process . This study is , therefore , the initial step for physical planning . For the purpose of this Comprehensive Plan a 21 . 5 square mile area including the existing corporate limits of the Town of Erie has been selected as the Erie planning area . The surveys and analyses presented in preceding sections of this Comprehensive Plan have provided basic data from which long-range physical development plans can be formulated . This data has led to the selection of the geographic limits of the Erie planning area on the basis of the following factors : a) The existing land use patterns . b) The location of political boundaries or man-made structures such as highways which are easy to define and describe . c) The existing circulation network. d) The location of the flood plains of Boulder and Coal Creeks . e) The location and extent of subsurface mining . f) The soil characteristics of the region. g) The topographic features of the region with specific regard to ultimately serving the area with sanitary sewer without the use of lift stations . 6-1 h) The location of the corporate limits of Lafayette , giving special consideration to the need for a low density buffer zone between the ultimate corporate limits of Erie and Lafayette . In accordance with the above described considerations the boundaries of the Erie planning area are defined as : Beginning at the intersection of State Highway 287 and Boulder County Road No . 7 ; thence , north along the east right-of-way of State Highway 287 to its intersection with the western limit of the 100 year flood plain of Boulder Creek; thence , along the western limit of the Boulder Creek flood plain to its intersection with State Highway 52 ; thence , east along the south right-of-way of State Highway 52 to the northeast corner of Section 5 , T1N, R68W, of the 6th P .M. ; thence , south four miles to the northwest corner of Section 28 , T1N, R68W, of the 6th P .M. ; thence, east along the north line of Section 28 to its intersection with the Community Ditch ; thence , southerly along the centerline of the Community Ditch to its intersection with Baseline Road; thence , due west along the north right -of-way line of Baseline Road to its intersection with the _ Boulder-Weld County Line ; thence , due north along the Boulder-Weld County Line to the southeast corner of Section 25 , T1N , R69W of the 6th P .M. ; thence , due west to the intersection of State Highway 287 and Boulder County Road No . 7 , the true point of - beginning. The method of developing the land use inventory proceeded from a field survey of land parcels which was conducted during September , 1972 . The various uses of the land were 6- 2 recorded under the classifications of agricultural land , residential , commercial , industrial and public and semi- public . A record of home occupations and land uses which would tend to change the existing character of adjacent land were also noted as well as individual locations for mobile homes . The following definitions will explain more clearly the categories of land use employed in this survey: Agricultural Land Land unimproved with urban type uses ; land used for agricultural purposes . Residential Land occupied by a single detached dwelling unit designed to accommodate one family . Commercial - Land used for retail sales , wholesale or service activities . Industrial - Land used for the manufacture , storage or fabrication of a commodity and mining . Public and Semi-Public - Land used for the Erie cemetery . Certain recreation lands are included in this category. A statistical compilation of the existing land use within the Erie planning area exclusive of the incorporated area of the Town is provided in Table 11 . The locations of these uses are represented on Plate 8 .

Develop- ment must properly suit the physical and social needs as determined from evaluation of local physical characteristics and the economic-population forecasts . General criteria and principles are set forth below as guidelines for develop- ment of the land use plan. These principles should be used to aid those involved in the implementing process of the Comprehensive Plan toward a better understanding of its various interrelationships and community-wide objectives . a . Development of land use arrangements to provide for the most economical and convenient use of land to satisfy the requirements of both the public and private development sectors . b . Provide for densities of land occupancy to suit the physical nature of the land and satisfy the principles of land economics . c . Provide for orderly development through extensions of existing land use arrangements and public facilities in order to prevent requirements for municipal administrative expenditures and development of physical improvements beyond the financial means of the community . d. Guide physical development in a positive direction as contributing to total environ- mental improvements including physical relationships as they may have an effect on social aspects . e . Maintain the business district of Erie as the dominant retail center of the community. 6-5 f . Develop a sound system of thoroughfares. capable of carrying anticipated traffic volumes within their specific function , and to satisfy the need for local travel convenience to points of desire . g . Provide for the highest population densities within the existing Town of Erie . h. Protect the agricultural aspects of the Erie service area especially in those areas where irrigation water is available for economic utilization of the land. i . Prevent the development of unsuitable land such as that located in flood plains or over mining areas and incorporate this land in an open space system which can be utilized for recreational uses . j . Establish selected areas for industrial use where such uses can utilize transportation routes such as railways and highways . The plan for the future use of land in the Erie Service area is shown on Plate 9 . Allocations of the land uses illustrated on Plate 9 are described below . In general residential uses have been allocated in a manner which will consolidate the highest residential densities adjacent to the core area of Erie . a) Agricultural - 1 dwelling per 3S acres , Irrigated farm lands that are agriculturally productive should remain in agricultural use with the provision that such land may develop into 3S acre lots when the need is demonstrated. b) Suburban Residential - 1 dwelling unit per acre . This land use allocation has been used in areas presently developing at a density of approximately 6-6 one dwelling unit per acre and in areas where higher densities may result in excessive scarring of the land through the construction of roads and other facilities . c) Low Density Residential 1 dwelling per 10 , 000 sq . ft . Density allocations of one dwelling unit per 10 , 000 square feet of land area have been made in those areas where the land capability in terms of slope , soil , access and other considerations will support such use . d) Medium Density Residential - 1 dwelling unit per 7000 sq . ft . Medium Density Residential use allocation has been used in those areas where sufficient open space has been identified adjacent to this land use to support and enhance such density . Northeast of the existing Town limits this use has been applied as a buffer between industrial and low density residential use . e) Commercial . This land use allocation has been applied to existing commercial areas or areas where this use would be a logical extension of existing commercial use within the Town of Erie . f) Industrial . Proximity to major highways and railroads was a prime consideration in the allocation of industrial use in the land use plan for the service area . In addition , the logical extension of existing industrial zoning within the Town was a factor in the allocation of this land use . g) Open Area . Open areas in the land use plan were selected primarily on the basis of undermining or in the locations of Boulder and Coal Creek flood plains . In certain 6-8 one dwelling unit per acre and in areas where higher densities may result in excessive scarring of the land through the construction of roads and other facilities . c) Low Density Residential 1 dwelling per 10 , 000 sq . ft . Density allocations of one dwelling unit per 10 , 000 square feet of land area have been made in those areas where the land capability in terms of slope , soil , access and other considerations will support such use . d) Medium Density Residential 1 dwelling unit per 7000 sq . ft . Medium Density Residential use allocation has been used in those areas where sufficient open space has been identified adjacent to this land use to support and enhance such density. Northeast of the existing Town limits this use has been applied as a buffer between industrial and low density residential use . e) Commercial . This land use allocation has been applied to existing commercial areas or areas where this use would be a logical extension of existing commercial use within the Town of Erie . f) Industrial . Proximity to major highways and railroads was a prime consideration in the allocation of industrial use in the land use plan for the service area. In addition , the logical extension of existing industrial zoning within the Town was a factor in the allocation of this land use . g) Open Area . Open areas in the land use plan were selected primarily on the basis of undermining or in the locations of Boulder and Coal Creek flood plains . In certain 6-8 cases , open space areas have been interconnected to provide an integrated green belt system within the plan.

For this reason reliable data on existing land use is of great importance in the preparation of a future land use plan. In order to obtain reliable data , the entire area of the Town of Erie was surveyed and individual uses of land were inventoried. The use of aerial photographs supplemented data obtained in the field survey . The existing land use analysis indicates good use , non-use , and misuse of various parcels of land within the corporate limits of the Town. Quantitative data on individual uses , coupled with mapping of these uses on Town maps establishes the groundwork for all long-range planning practices . Eight classes of land use were recognized in the Town of Erie . A list of these uses along with a brief definition of each is as follows : a . Vacant land - Any land parcel or group of parcels which is unimproved and which is located within an area of developed urban functions , including those by-passed land parcels being used for agricultural purposes . b . Residential - Land occupied by single , detached dwelling units . c . Mobile Home Residential Land occupied by mobile home units , regardless of the type of foundation . d. Residential Commercial - Land occupied by a joint residential and light commercial use which satisfies a home occupation designation. 7-1 e. Commercial - Land used for retail sales , whole- sale, or service facilities . This category includes restaurants and commercial recreation facilities , and other related types of use. f. Industrial Land used for the manufacture, storage , fabrication or transport of a product , and all land on which mining has recently been conducted. g. Public and Semi-public - Land used by Federal , State or local government which serves a public purpose, such as land for schools , parks , or recreational areas ; also land used by non-profit entitites such as churches , clubs and charitable organizations . h. Agricultural - Land used for farms , pastures , or any agriculturally related function. Table 14 outlines the existing land use in Erie . The distribution of these land uses is illustrated on Plate 10 .

This large percentage of vacant land makes the present planning operation somewhat easier . Allocation of vacant land for future integrated land use is more easily facilitated than the condemnation of improved land for new and different future uses . Vacant lands are predominantly located along the perimeter of the Town and along the Chicago-Burlington- Quincy Railroad right-of-way running north and south through the town. The largest single tract of vacant land is that portion of the Town located in Boulder County which was annexed in September 1970 . Detached single-family housing is the second largest land use observed in the Town of Erie and consists of 85 . 62 acres or 8 . 02% of the total land area of the Town. Residential development is scattered throughout the community, with the heaviest concentration along Main, High, Holbrook, and Pierce Streets . Mobile homes , which , for the purposes of this study , are considered in the same category as single-family residential units , account for 9 . 64 acres or 0 . 90% of the total land area. Mobile homes are primarily located along Kattell , Briggs , and Pierce Avenues . The third largest use of land is for streets and alleys , with a total area of 71 . 93 acres or 6 . 74% of the land area within the Town allocated for this use . Except for Chessman and Briggs which are paved with asphaltic material , all streets in Erie are dirt roads and are exceptionally muddy during the wet seasons . The Chicago-Burlington-Quincy Railroad crosses all of the east-west streets along its path and runs diagonally for two blocks in the middle of High Street . The present location of these tracks , as will be discussed in depth later , is in conflict with every aspect of public safety and sound planning. Alleys are , without 7-4 exception, present in every block. In the past , alleys have played an important role in the extension of public utilities to individual dwelling units and have contributed to traffic circulation within the Town. Changes in design and technology no longer warrant the existence of alleys . The use of cluster development without alleys and utilizing curvelinear streets is recommended as the future development technique for the vacant land within the community . Public and semi-public uses , which for the most part involve churches , schools , parks , the town hall and a fire station, account for 31 . 42 acres or 2 . 94% of the total land area . The location and size of several of the public facilities do not conform to good planning practice and, as will be seen in the future land use plan, recommendations are made to correct these problems . Residential-commercial land use , which is another extension of residential use , accounts for approximately 0 . 52 acres or 0 . 05% of the land area, and consists of two establishments , on the north and south sides of Briggs Avenue . Commercial and industrial establishments account for 2 . 45 and 3 . 18 acres or 0 . 23% and 0 . 30% of the total land area, respectively. The bulk of the commercial establishments are located along Briggs Avenue . Limited commercial facilities are noted at the intersection of Chessman Street and County Line Road. Industrial land is found in three locations ; on the corner of Anderson and Kattell , on the corner of Moffat and Briggs , and on the north side of Balcolm at County Line Road. 7 -5 7 . 2 Future Land Use Within Erie Nine separate categories of land use have been incorpo- rated into the future land use plan for the existing Town. Table 15 itemizes the allocation of these various land uses and Plate 11 illustrates their location within Erie .

Three major factors have influenced this planning decision. First , in accordance with the thoroughfare plan Kattell Street will be the major collector road through the Town. This road, which should eventually be developed into a four-land boulevard, carries the traffic to and from the north- west section of town to the southeast section of the community while by-passing the center of Town. This peripheral road contributes greatly to the traffic circulation through the core area . A peripheral road of this nature permits higher traffic volume and is therefore desirable in areas with the highest densities . Secondly, the Coal Creek floodplain and the Town park east of Kattell could be designed and integrated into an open space and parkway system traversing the eastern limits of the core area . Although the entire system will be used by the public , the residents of high density developments can make the best use of the system on a daily basis . Finally, 7 -6 -- the location of residential structures with the highest density on the eastern edge of Town will not block the view of the mountains to the west for the rest of the community. The view of Longs Peak and the Rocky Mountains is one of the most valuable natural assets of Erie and should be protected in every possible way . West of Kattell Street the density of the residential areas decreases , providing a gradual transition from the highest to the lowest densities in the Town. The bulk of the medium high density uses are located along Briggs and Pierce Streets and adjacent to the central business district on the north. The lowest density uses are located on the west edge of Town with frontage on minor collectors or local streets . The internal streets for large parcels of low density developments are not shown on the Land Use Map in the hope that future developers will use imagination and ingenuity in the design of these parcels . It is recommended that developers of all large parcels employ Planned Unit Development techniques to achieve a well integrated development . Public and semi-public land with a land area of 24 . 16 acres consists of three large sites : (1) the junior and senior high school site , (2) the elementary school site , and (3) the civic center complex . Although the location of other public and semi-public uses is not defined on the Land Use Map , it should be understood that churches , small neighborhood parks and elementary schools should be allowed wherever and whenever the demand warrants them. The integration of public anc semi- public uses with residential and commercial uses is not contrary to the provisions of this Land Use Plan, and is actually recommended. This approach has been used very effectively in designing planned unit development throughout the nation . 7 -8 Park and recreation uses have been established along the length of the Chicago-Burlington-Quincy Railroad to provide a buffer zone between the railroad and adjacent uses. This land may be developed into parking lots , small neighborhood parks and tot lots . The areas, along the tracks that are to be developed for residential purposes should contain sufficient open space areas along the tracks to buffer the effects of the railroads on the residential uses . It is hoped that the rail- road companies will consider a relocation policy once Erie has begun to implement this Land Use Plan. Usually, planners have the tendency to combine public , semi-public and open space uses into one category. In Brie , due to specific physical and natural limitations , it was necessary to distinguish between such uses . In general , the open space category refers to land above undermined areas or land located within the 100-year floodplain of Coal Creek. Since these areas are not generally suitable for the con - struction of permanent structures , it is recommended that they remain in their natural state or be utilized for recreation oriented uses such as parks , driving ranges , golf courses , or picnic areas . The areas indicated as such open space on the Land Use Plan may be reduced in extent if adequate proof is supplied to the town administration that encroachment into these areas by structures will not create a public hazard and will be in the best interests of the community. Park and recreation land does not bear any restrictions and can be developed for any of a variety of uses . Future development patterns will be strongly influenced by the recent annexation of land within Boulder County. Sub- stantial residential construction should occur in this area . As a result , a basis will be established for the development of new shopping facilities in this location. It must be cautioned, however , that over-development of commercial land 7-9 in the Boulder County portion of the Town will have the effect of draining the economic life of the existing central business area of Erie to a point of abandonment . There is, no question but what the southwest portion of the Town should be supplied with shopping facilities to adequately and conveniently pro- vide services to the people who will live there , but two important development objectives are apparent ; a. That the existing Central Business District of Erie is the focal point of the community and , because of its influence as the business and governmental center , should be modernized, upgraded and the problems of blight eliminated . b . Caution should be exercised in all land use development proposals so that competition will not develop between Erie and the Boulder County addition giving the connotation of "old and new Erie" . All development should be influenced to occur within a "total community" context with balanced land use proportions . The original commercial area within the Town along Briggs Street has been reduced to a six square block area to consoli- date commercial functions within the core area of the community. Finally, the industrial category is used to accommodate light industrial activities such as warehousing , light manu- facturing , and other similar operations , as long as excessive noise , glare , fumes and obnoxious odors are not associated with these operations . Table 16 itemizes the number of dwelling units and the population densities for the incorporated area of the Town of Erie in accordance with the future land use plan. 7-10 Min.

The development of 2568 units in the core area will be slow and gradual and for the most part dependent on the progress of other aspects of the plan. Usually the demand for high density residential developments comes about after the area has established an economic base which in turn expands the population and the demand for housing . 7-11 SECTION 8 THOROUGHFARE AND STREET PLAN The purpose of the Thoroughfare Plan is to insure that the development and construction of future streets and thorough- fares is made in a manner which provides for the most efficient , convenient , and safe movement of people and goods within the planning area . An efficient street system must provide for maximum freedom of movement , and at the same time , a minimum of interference with adjacent land uses and activities . Such a plan involves establishing a network of streets and highways which serve all necessary functions . Some streets are for movement and some are for access and parking . Other streets are for combined uses . The Thoroughfare Plan links all streets and roads together into an overall system. The plan should provide an efficient connection of functionally related activities within the urban area , and also should provide convenient access to other areas within the region. The Thoroughfare Plan pro- vides recommendations for improvement of existing streets and construction of new routes to accommodate the increased vehicular traffic which results from growth of the area . In Erie , this study relies upon current data available from the Colorado State Highway Department and the Boulder County Planning Department . The conclusions and recommenda- tions have given careful consideration to the road and traffic studies of these agencies . The existing street design in the Town is styled after the grid system. This system is comprised of equally spaced streets which run perpendicular to each other . The blocks generated by this system are rectangular in shape (400 ft . x 320 ft . ) with the longest dimension in the north-south direction. Each block contains a 20 foot wide alley which runs north and south along the rear lot lines . Streets and avenues have a uniform right-of-way of 60 feet . The original plat of the 8-1 Town indicates a uniform lot line dimension of 25 feet x 150 feet giving each lot a total area of 3 , 750 square feet . There are three major traffic barriers in and around the community . These are the tracks of the Chicago , Burlington and Quincy Railroad, the tracks of the Union Pacific Railroad and the channel of Coal Creek. The tracks of Chicago , Burlington and Quincy Railroad bisect Erie in a north-south direction. The tracks of the Union Pacific Railroad traverse the eastern and southern limits of the Town and the channel of Coal Creek traverses the eastern and northern portion of the community . Generally speaking , these barriers have controlled the directions of growth in the city . Although the effect of this control would have been more pronounced if Erie had experienced a steady growth trend in the past ; the influence of these barriers is still apparent . These barriers will continue to influence the growth directions of the Town in the future and it is the objective of this Thoroughfare Plan to provide an orderly development of grade separated crossings and bridges so that the interference or contact with these barriers is kept to a minimum. It is also the intent of the Thoroughfare Plan to reduce construction and on-going maintenance costs of future thoroughfares within the region by designating future road extensions in areas where development , topography and other physical barriers will not result in excessive costs . Finally, the existing street network must be used as the basic frame- work for future street development . Although this does not necessarily suggest that all streets should remain in their original layout , it rather suggests a conformity with the existing system. Transport modes and transport facilities are required to provide many of the basic necessities for daily living as well as materials and equipment used in local processing and 8 -2 manufacturing . There are few items produced , consumed or exported which have not been moved by more than one mode of transportation. The relationships between different types of transportation facilities are subsequently interdependent . Design of each system contributes to the overall value of the entire system, especially in terms of its function in the local area . Streets should be classified, designed and constructed according to the function they serve . For example , in residen- tial land use planning and development , street functions differ according to purpose , traffic volumes and density of develop- ment . Differences in function determine the right-of-way and pavement widths to be provided . All streets in the Erie planning area are divided into the following types for planning purposes . a . TT�p�ee __1__ - Freeways - Expressways A Freeway is aided multilane Arterial for through traffic with full control of access and all grade cross- ings eliminated . An Expressway is a divided multilane Arterial for through traffic with con- trolled access and with some crossings at grade . Type 1 streets are usually planned for initial Expressway construction with ultimate conversion to full Freeway standards . b . Type 2 - Arterials - An Arterial is a continuous access controlled street for through traffic with crossings at grade . c . TT e 3. - Collectors - A Collector is a vicinity- wide continuous access street connecting Local Access Streets to Arterials . d. Type 4 - Local Access Streets - A Local Access Street provides direct access from abutting properties to other streets . e . Type S Frontage Streets - A Frontage Street serves as a Collector or Local Access Street used contiguous with higher type streets to control access . 8-3 All Town streets are also divided into the following five classes for administrative purposes . Class I streets constitute the Town Primary System. Class II and Class III streets con- stitute the Town Secondary System . Class IV and Class V streets are not a part of the Official Town Street System. a. Class I Streets - Class I streets are high-type , hard-surfaced streets constructed and maintained by the Town or other governmental agency , to pro- vide year long , all weather routes for high volume public traffic . Freeways , Expressways , and Arterials are Class I roads . b . Class II Streets - Class II streets are hard- surfaced streets constructed by others and maintained by the Town or other governmental agency, to provide year long , all weather routes for public traffic as available funds , manpower , _ and equipment permit . Collectors and Local Access Streets in Flat or Rolling Terrain are Class II streets . c . Class III Streets - Class III streets are hard- surfaced , minor streets constructed by others and maintained by the Town or other governmental agency, to provide limited passage to remote properties as available funds , manpower , and equipment permit . Collectors and Local Access Streets in Steep Terrain are Class III streets . d. Class IV Streets - Class IV streets may or may not exist physically on the ground and are not improved or maintained by the Town. Streets are accepted as Class IV streets to reserve rights-of-way for future street development . e . Class V Streets - Class V streets are private streets constructed and maintained by others . Class V streets are limited to closed loops , dead-end streets , or other streets not likely to be extended or added to the Town Primary or Secondary System. In accordance with the previously described classifications the following long-range recommendations are made in regard to major thoroughfares within the Erie planning area . Plate 12 illustrates the major Thoroughfare Plan for the Town of Erie . 8 -4 a. The Pearl Street Valmont Road - Isabelle Road alignment from the City of Boulder is extended to bypass the core area of Erie to the south and connect with Perry Street in the southeastern portion of the community . This major arterial road is to be extended east to make contact with I - 25 at an existing inter- change diamond along the alignment of Weld County Road No . 8 . This road intersects several other major roads along its east-west alignment and the proposed extension will eventually bring Erie into faster and easier con- tact with other communities in the region. The pro- posed road is classified as an arterial road having a right-of-way of 120 feet (Class I - Type 2) . b . The extension of Jasper Road is proposed to inter- sect with the northern extension of Kattell Street in the northeast section of Town . This collector road , with a right-of-way of 80 feet (Class I - Type 3) , provides circulation around the core area without hindering the core area business , commercial and civic center activities . High density residential develop- ments along this road are in immediate contact with major employment centers of the region. As a conse - quence , of this extension and the elimination of Cheesman as a collector , two immediate benefits become apparent . First , the bulk of the traffic is funneled to Kattell Street , bypassing the two existing schools at the corner of Cheesman and County Line Road. Second , the extension of Jasper Road to the east eliminates the two sharp curves on the primary route to Erie from the west . These curves are exceptionally dangerous to the stranger in the area and to all residents during the winter months . 8-6 c . County Line Road, which should gain more use in time , is proposed to be developed as a north-south collector with a right-of-way of 80 feet (Class II Type 3) . This road enables vehicular movement from the north section of Town and State Highway 52 to the south part of the Town and State Highway 7 . d. The remaining streets within the Town and the service area should be developed as local streets with 60 foot rights -of-way (Class II - Type 4 and Class III - Type 4) . The main purpose of these roads is to provide access to abutting properties and they do not generate sufficient volumes of traffic to warrant wider rights - of-way. Perry Street on the south part of Town is proposed to extend westward to County Line Road to provide east-west circulation Although this extension was requested by the Town, the probability of this extension ever becoming a reality seems slight . The problems involved in crossing two railroad tracks in a limited horizontal distance make this extension unfeasible . Grade separated crossings would require at least 1 , 000 feet of cut and fill to accommodate an underpass at 6 percent grade for this extension. This is an expensive approach and would create the additional hazards of flooding and icing in wet seasons . As an alternate route , the combination of Pierce and Balcom Streets can provide a temporary east-west exit through Town. Their usage as a collector should diminish as other proposed routes are developed. In addition to measures already discussed, other steps should be taken to further improve the vehicular circulation within the Town of Erie . Plate No . 13 illustrates some of the recommended alterations and improvements . These include the elimination of some of the existing roads to reduce interference with the railroads and eliminate hazardous intersections . For 8-7 the most part , these streets do not contribute to the circulation of traffic through Town and in certain specific locations have the opposite effect . Street improvements such as surfacing and curb and gutter are proposed for all streets in Erie . Under present conditions , these streets are not adequate for vehicular or pedestrian movements . The condition of these roads become worse with moisture . Therefore , it is recommended that all streets in Erie are to be surfaced with asphaltic materials and that curbs , gutters and a storm drainage system be provided. Sidewalks , pedestrian walkways and bike trails should be provided to encourage non-vehicular circulation . 8-9 SECTION 9 CAPITAL IMPROVEMENTS The following capital improvements program brings together the major and immediate capital improvement needs for Erie. The Comprehensive Plan outlines major items of improvement which the community will require as development of the planning area progresses . Through sound programing of capital improvements the total fiscal planning of a community becomes more functional since it is included as a part of the annual budget decision. There are many items that are not included in the following tabulation. The improvement needs listed are those considered essential for Erie to accommodate any material growth and are those items which are of immediate and serious concern. Other improvements which are not directly related to the survival of the Community as a viable entity are not considered here in that secondary improvements will be of - no value unless the Town pursues the following described needs immediately.

The process of implementation requires coordinated efforts of the Town' s appointive and elective officials . Furthermore, the process should be viewed as an encompassing community effort in its implications of _ total community development , being limited not only to aspects of physical improvement, but equally related to total environment . As important as implementation appears to be, the process becomes ineffective without direction from the recommendations of the Plan and coordinated citizen support . A lack of citizen interest and apathy on behalf of the appointive boards has marked the failure of many progressive planning programs . Only with public involvement can the Erie Plan become the framework for the future of the _ Town. Thus , scheduling of systematic implementing procedures based on the time intervals and objectives of the Comprehensive Plan becomes essential . Colorado State statutes form the legal basis for comprehensive planning by providing for the organization of planning commissions of an advisory nature to elected officials and charges them with the responsibility of developing the Plan as well as other certain administrative duties . As a part of the Commission' s general coordination and advisory duties the Commission is also responsible for implementation of the Plan. State Statutes also establish certain processes for plan implementation by providing for the adoption and enforcement of specific controls and regulations designed to further the concepts contained in the Comprehensive Plan. In the case of Erie the adoption of the 10-1 following Ordinances and regulations will be essential to provide the necessary supporting laws to implement the Plan. a) Revised Zoning Ordinance and Zoning Map b) Detailed Subdivision Regulations c) Flood Plain Ordinance d) Street and Road Standards e) Water System Design Standards f) Sewer System Design Standards g) Revised regulations for the sale of water in-town h) Revised regulations for the sale of water outside-town i) Revised Sanitation District Rules and regulations including special provisions for outside-town sewer service To complement these means for implementation and to reinforce the basic framework of the plan, a system of supplemental codes is often adopted by communities , most common of which include nationally recognized model building, housing , plumbing , electrical and fire prevention codes . From the preceding comments , it is clear that the Planning Commission' s administrative obligations cannot be fulfilled unless the Comprehensive Plan has legal recognition and legal status as an "Official Plan". It is therefore recommended that this report be adopted as the Comprehensive Plan for Erie under procedures outlined in State planning statutes . Finally , the respective administrative and elective Boards of the Town of Erie must recognize that Erie cannot 10-2 progress and maintain a position as a viable community alone. Implementation of the Comprehensive Plan also requires that the needs and desires of other political subdivisions of the State of Colorado be ser ved. Erie must elicit support from and contribute support to the the various local and regional planning entities which are involved to some degree in the Erie planning area. Erie must also develop a working relationship with the Left Hand Water Supply Company and the City of Lafayette to assure harmonious and mutually beneficial solutions to common problems . 10- 3 BEFORE THE WELD COUNTY PLANNING COMMISSION RESOLUTION OF RECOMMENDATION TO THE BOARD OF COUNTY COMMISSIONERS Moved by J .

Box 98 Erie, Colorado 80516 Gentlemen : The Larimer-Weld Regional Council of Governments in its regularly-scheduled monthly meeting on January 12 , 1977 , reviewed the application for $1 , 358 , 880 for Steps II and III Environmental Protection Agency Construction Grants funds and Colorado Department of Health funds for the Erie Water and Sanitation YDistrict, Waste Treatment Facilities Plan At that meeting, the Council elected to not make comment on the review of the proposed project. The staff, however , was instructed to communicate its concerns to the Town of Erie and the Erie Water and Sanitation District. The following is offered as a recommendation for your consideration before any final actions are taken by your Board in support of that plan. 1. The future population estimates for the Erie area are based on optimistic views of growth in Weld County. Less than 10 percent of the facility' s planning area in Weld County is within the Northern Colorado Water Conservancy District (NCWCD) or eligible for inclusion in the NCWCD service area. This condition severely restricts the availability of domestic water for future development and may ultimately affect the amount of population growth occuring in the waste treatment facility' s planning area. The ultimate outcome could be increased user charges to existing customers on the sytem. RECOMMENDATION: An investigation be made by the Erie Water and Sanitation District' s consulting engineer assuring that adequate domestic water resources are available to serve anticipated growth areas in Weld County which would be serviced by the system. 2 . In light of proposed Environmental Protection Agency regulations of September 2 , 1976 , which would relax the suspended solids limitation for waste stabbiliZossibility tion ponds under 1 MGD , there exists a very good P 2/1 -72,2_2( //e/- /7 7 Erie Board of Trustees Page Two January 14 , 1977 that a less costly waste treatment alternative may be available for the Erie area, while allowing the waste discharge to meet current and future water quality standards. Recent staff communications with the EPA in Washington indicated that the proposed regulations have an excellent possibility of being adopted as written in draft form by February 1977 . Selection of a less costly waste treatment system would then be available for the Erie area. This would eliminate the need for an expen- sive mechanical waste treatment plant with considerably higher operation and maintenance costs. The ultimate outcome of this action would be reduced user charges to existing and future customers on the system. RECOMMENDATION: A cost-effectiveness analysis of an aerated waste stabilization pond be prepared, and the results of the analysis compared against other waste treatment alternatives in the facilities plan. We very much appreciate the opportunity to comment on the proposed project and hope that you and the Erie Water and Sanitation District can find a satisfactory solution to your waste management problem. If we may be of further service to you, please feel free to call.
