To Board of County Commissioners Date November 3. 1982 W® Weld County Planning Commission /272 COLORADO From Rod Allison, Current Planner krr Subject: Mountain Shores Sewage Treatment Proposal Mountain Shores Subdivision is submitting an application for site approval for a sewage treatment proposal. This is the second sewage treatment site application to be considered for a recommendation to the State Health Department, Water Quality Control Division. The present site application proposes to pump through a force main to the downstream side of the Union Reservoir Outlet. Irrigation outflows and seepage will dilute the treated effluent as it travels via the Union Reservoir Ditch to its intersection with the St. Vrain River. The Colorado Department of Health has established regulations for quality of effluent. A letter dated October 27, 1982, from the Weld County Health Department indicates that the Weld County Board of Health approved the site applica- - tion. A letter dated June 1, 1982, from the President of the Union Reservoir Company indicated that they have no objections to the proposed site application. The Department of Planning Services staff recommends that a recommendation of approval be forwarded to the Water Quality Control Division of the State Health Department. The staff recommends the following conditions if the Planning Commission recommends approval of this site application: 1. The operation of the system be by a private consumer entity with appropriate arrangements with Weld County (as provided for in 30-20-401 et seq. , CRS. 1973 as amended) for the protection of public health. The arrangements with Weld County shall address the continued maintenance, operation and repair of all sanitation drainage and sewer treatment facilities, as well as the authority of Weld County and the Homeowner's Association to enforce said arrangements. These shall be made prior to the County's approval of a final plat. 2. The developer be responsible for construction of the facility and appurtenances. 3. Proper easements and legal access be acquired for the collection and discharge facilities and the plant before the County's approval of a final plat. 4. The system's infrastructrue be compatible with the city of Longmont's requirements to facilitate efficient transfer. i i Board of County Commissioners Weld County Planning Commission November 3, 1982 Page 2 5. Contingency plans should be made regarding back-up for power outages and other temporary downtime conditions for all mechanical elements. 6. No effluent discharge shall be released to Union Reservoir; and 7. Weld County must approve a final plat for the proposed develop- ment and be assured that all legal and financial requirements are in order prior to construction of the plant. Conditions 4 through 5 should be made part of any approval by the State Health Department if found to be appropriate for this request; and 8. The owner and/or applicant shall develop an agreement with the property owners immediately below the Union Reservoir outlet (Spring Gulch) that the discharge will be affecting. • . • at ,rl, R E U inkTo Rod Allison, Planning Date October 27, 1982 COLORADO From Ron Stow Environmental Health Services r /CY I / Subject: Mountain Shores Subdivision J/ On Tuesday, October 26, 1982, the Weld County Board of Health approved the site application for the sewerage plant and outfall of the Mountain Shores Sub- division north of the Union Reservoir. i The Board's major concern was whether those residents ,at and below the proposed sewage outfall into the Union Reservoir Ditch will be notified of the planned operation and what concerns they may have.

Box 449 Greeley, Colorado 80632 June 1 , 1982 Board of County Commissioners of Weld County 915 10th Street Greeley, Colorado 80631 Re : Mountain Shores Subdivision Gentlemen: The Mountain Shores Subdivision developers have met with Union Reservoir Company relative to the effluent arising from the sewer facility coming from the subdivision and have agreed to construct a pipeline to carry said sewage effluent around the Union Reservoir. In order to accomplish this , the best location for the right of way for such pipeline would be along Weld County Road No. 1. The Union Reservoir Company wishes to endorse and request your granting of any application for a right of way for such sewer line in the county road right of way. The only natural and clear course for the pipeline would be in the county road or one of its borrow pits . It would be cumbersome and expensive for the subdivision developers to acquire a right of way from private landowners ; and as this does serve a valid public purpose , it would be consistent for an eventual connec- tion with the municipal sewer system of Longmont . The Union Reservoir Company wishes to express its appreciation for the consideration extended by the Board of County Commissioners in resolving this difficult problem. Without the support of the County Commissioners to get this sewer problem resolved , it would remain a severe health threat to the Reservoir and its users. The pattern adopted by the parties in resolving this particular subdivider' s sewer problem should be followed by those seeking subdivisions in the future within the Union Reservoir drainage basin .

SHORES SUBDIVISION SEWAGE TREATMENT PROPOSAL SITE APPLICATION REFERRAL FROM STATE HEALTH STAFF ANALYSIS The County must be concerned with two levels of concern regarding this request. The first is the physical effect of the sewage treatment facility; the second is the concern of the County regarding the financial and legal obligations for the systems operation. The physical effects to be considered primarily are associated with: 1. The site's limitations or attributes to house a system, including proposed effluent discharge; 2. Effects on the neighborhood from the type of system proposed; 3. System backup capabilities in the event of downtime and inability to discharge the effluent; 4. Effect on area water table due to surcharging by effluent discharge; 5. System capacity in relation to proposed user demand (volume of sewage per household X no. of households) ; and 6. Expansion capabilities and effects of expansion on above factors. The treatment system proposed (extended aeration) and land application of the effluent appears to be a satisfactory system. The extended aeration system provides a reliable treatment with minimal odor. The proposed location is not immediately adjacent to intensively developed land but is within a proposed residential development which may utilize the system if Longmont service is unavailable. Disposal of the effluent is proposed to be by ground application for irrigation. The present proposal indicates the overall application rate as moderate, however, if rates are increased with additional development or if intensive application is made over shorter periods, what effects can result to groundwater and soil stability in the area? Based on the soils report for Mountain Shores Subdivision, design limitations must be followed for home construction. Are there known limitations for how much irrigation can be applied before these limitations are further affected? • • Storage requirements for the treated effluent have been based upon seasonal constraints. The storage should be provided for adequate cushions in the event that seasonal constraints are greater than an average condition. Should the storage pond(s) be provided with aeration to prevent possible odor problems if any odors can be expected? The sewage is proposed to be lifted to the treatment site. What constraints exist if the lift station is temporarily without power or out of commission? What are the potential effects from such an occurrence? The financial and legal effects to be considered are: 1. Cost of initial system construction; 2. Cost and methods of payment for the continuing operation and maintenance of the facility; 3. Legal right to have access to the facility, outfall line(s) , and trunk line(s) for maintenance purposes; and 4. that the system can be closed down and appropriate fees paid to Longmont at such time as service is available. The present information does not provide a complete analysis regarding system costs and ability to pay such costs by future homeowners. It is anticipated this information will be available to the Planning Commission for their review on April 20, 1982. The legal aspects must be subject to scrutiny and acceptance prior to approval of the final plat. Until the system is approved by the State Health Department it is not deemed necessary to establish final legal language, however, it is appropriate to know how these issues will be approached. The staff recommends the following conditions if the Planning Commission recommends approval of this site application: 1. The operation of the system be by a private consumer entity with appropriate arrangements with Weld County (as provided for in 30-20-401 et. seq. , CRS, 1973 as amended) for the protection of public health -- arrangements being made prior to the County's approval of a final plat; 2. The developer be responsible for construction of the facility and appurtenances; 3. Proper easements and legal access be acquired for the collection and discharge facilities and the plant before the County's approval of a final plat; 2 0 4. The system's infrastructure be compatible with the City of Longmont's requirements to facilitate efficient transfer; 5. Specific controls be designed and implemented by the developer to control amounts of application within the subdivision vicinity with a mechanism to direct effluent to the adjacent farm for irrigation use; 6. Treated effluent storage design should accommodate the extreme "worst case" need -- consideration of storage on the off-site farm site should be considered; 7. The applicant should present the design and requirements for aeration or other acceptable odor control for the storage ponds (if such odor control is shown to be necessary) ; 8. Contingency plans should be made regarding backup for power outages and other temporary downtime conditions for all mechanical elements; 9. No effluent discharge shall be released to Union Reservoir; and 10. Weld County must approve a final plat for the proposed development and be assured that all legal and financial requirements are in order prior to construction of the plant. Conditions 4 thru 8 should be made part of any approval by the State Health Department if found to be appropriate for this request. 3 • • Union Reservoir Company P.O . Box 449 Greeley, Colorado 80632 March 26 , 1982 Weld County Commissioners Weld County Complex Greeley, Colorado 80631 Gentlemen : • It is understood the Board of County Commissioners of Weld County is again considering a sewage system which could adversely affect the Union Reservoir. No notice has been given Union Reservoir Company of this further consideration. Union Reservoir Company is quite concerned about the possible approval of sewage treatment facility proposed for a 280-unit sub- division by Calkins Lake II , Ltd. Partnership - Mountain Shores Subdivision. As stated in previous letters and meetings before the Commissioners , the proposed subdivision is north of Union Reservoir and any discharge of effluent into Union Reservoir would cause considerable damage to Union Reservoir Company. The Company receives almost all of its income from a recreational lease of the reservoir and the Company fears that even in the event that there might possibly be any discharge of effluent into the reservoir that the lease will be terminated. Loss of the lease would mean that the stockholders would be paying higher assessments for the irrigation water. There are also a greater number of people provided recreation by the reservoir than would be benefitted from the development of Mountain Shores Subdivision. Union Reservoir Company urges that any sewage treatment system for the subdivision not be approved until it has been presented to the Company and received the Company' s approval. The Company will not withhold its approval arbitrarily, but feels it must protect its interests and those of its stockholders in this matter since it can have such great influence on the Company. 1 “----r----1-7,--,.y y _1 Yours very truly, li UNION RESERVOIR COMPANY I G i' - 7 ��II_J By �-w_..b� Weld Co.

At its most recent meeting of the Board of Directors , the Directors determined that if approval is granted on the sewage treatment facility without prior approval of the system by Union Reservoir Company that the County will be held liable for any damage caused by effluent discharged into the reservoir , including damage from loss of recreational lease currently in effect on the reservoir.

The plant's location is shown on the back page of the enclosed packet. All of the needed information given to Longmont Commissioners and their reasons for turning down the request are included. Our signed petition shows we do NOT want the health hazard this plant will produce. The odor that will come from this type of plant will be horrendous. There seems to be no way to control it. The hazard of a breeding nond for mosquitoes carrying diseases will be un- believable. The development of homes in this area is questionable at this time. Our schools are subject to overcrowding now. Our police and fire protection is only adequate. Also checking with the Longs Peak Water Association, we were told that the line running south of US Highway 66 and Weld County load 1 is at the present time inadequate to carry the new subdivision. As homeowners and taxpayers (as you are topwe're sure) we strongly object to the building of the waste water treatment plant. Thank you for your consideration on this matter.

Pia„mng C_roidiCaaa • I 13662 Elmore Road Longmont, Colorado 80501 April 12, 1982 Mr. Hahn Planning and Zoning Commission Weld County Courthouse Greeley, Colorado Dear Mr. Hahn: Unfortunately, the meeting concerning the proposed waste water treatment plant was held during working hours and I was unable to attend. There- fore, I would like to express my concerns in this letter. After living near one sewage plant, I am extremely opposed to another. I have experienced the trauma of foul air, insects, and decrease in property value. Due to odor, one neighbor had to accept $10,000 less than appraised value when the house was sold. Numerous meetings were held to prompt the county to "do something" in order to correct this odorous health hazard. Finally, after many confrontations and publicity, the plant was covered, at great expense to the county. Each development should not have its own sewage plant. Instead, the matter should be studied on an extensive basis so that a large area would be serviced by a quality facility. The current proposal is setting the wrong precedent! Another major concern is the poor, clay soil, high water table, and low saturation level of this area. During heavy rains and melting snow the ground is totally saturated, with limited drainage. We have experienced water seeping up through basement drains. Using the washing machine, flushing toilets and taking baths only added to an already serious problem. After extending our leech field and plugging drains, we determined nothing more could be done except to wait for the soil to dry. Since we are on the downslope from the neighboring field where the plant would be situated, I am extremely concerned about the health hazard this would create if bacteria, chemicals, etc. were to seep into our homes or lie stagnant for days in the clay soil. I cannot believe the most "careful" planning could remedy this situation. I am suspicious that the developer knows the soil situation and septic tanks near the lake would be an impossibility? Why should we suffer for his gain? I cannot express strongly enough my opposition! The statements I have made are honest and without exaggeration. Please review the proposal carefully and prevent the establishment of the plant until a long-range plan can be developed to serve anticipated growth in this area. Thank you.

Subject site is outside of the City's Prime Urbanized Area. We do not anticipate this area being considered for inclusion into the PUA for quite some time. The City cannot provide any services to the area including water and sewer. With this in mind, we have the following questions whose answers should be considered by those having jurisdiction in this matter: 1 ) How does the proposal relate to the Weld County Comprehensive Plan which designates the area Agricultural? 2) How does such a proposal relate to the following policies for residential type development in the Weld County Comprehensive Plan? a) New residential developments which are not clearly connected to and served by municipal utilities and services shall be discouraged. b) Proposals for new residential development adjoining existing municipalities shall be encouraged so long as they conform to the desires of the towns as expressed in their comprehensive plans. 3) Can all services (police, fire, water, storm drainage, schools, street maintenance, etc. ) be adequately provided to the area? 4) Is the proposed treatment plant being viewed as a permanent solution to sewage disposal ? Is the service area adequate to financially support long-term maintenance responsibilities? Thank you for the opportunity to comment.

The Association will also be responsible for any plant failures and damages resulting from plant failure. Implementation Plan and Schedules 11 Construction of the first phase of the treatment facility serving only Mountain Shores Subdivision is scheduled to begin in late spring of 1982, with start-up in fall of 1982. Plant flows will reach design capacity of 20, 000 gpd at the end of Mountain Shores' projected three-year buildout period. A bar chart showing scheduling is attached. Long-Term Plans The treatment facility will initially be sized to serve only Mountain Shores residences for a total fldw of 18, 600 gallons per day. This plant will accommodate wastewater 1 flows during and after Mountain Shores' three-year buildout period. Before Allen and Kelley-Tiao developments begin to contribute wastewater flows, arrangements will be made to treat their waste. There are two options at this point. The preferred alternative is that the City of Longmont will be able to receive wastewater from all three developments. In that case, the plant will be removed from service and Mountain Shores wastewater will be treated at the Longmont facility. If Longmont again refuses to serve the developments, the facility can be expanded to serve Allen and Kelley-Tiao. The projected increased flow is 80, 000 gpd, and the facility site will be designed to leave room for this contingent expansion. Every attempt will be made to reach an agreement with Longmont, thereby avoiding treatment plant expansion. Other Area Developments Properties surrounding the Mountain Shores, Allen, and Kelley-Tiao parcels are smaller lots that are zoned agricultural. There is not much additional development possible in this rural area. For that reason, the plant would not be expanded beyond the possible 80, 000 gpd capacity. Potential Longmont Service The City of Longmont has refused to serve Mountain Shores Subdivision because of topography, distance, and its Legal Arrangements Controlling Site The plant will be built by the developers, and ownership will be deeded to the Homeowner' s Association or to the Sanitation District if one is formed. The Association or District, through its manager and directors, will be 11 responsible for control of the plant site and of the open areas where effluent will be applied. Institutional Arrangements A Covenant Agreement through the Homeowner' s Association will insure that only domestic wastewater, no industrial or commercial wastes, will be generated in the service area. The plant will be designed for secondary treatment of residential wastewater with no facilities for treating unusual chemical discharges. • Management Capabilities It will be the responsibility of the Homeowner' s Association or Sanitation District Board of Directors to control any extensions of the service area or changes in population density within the area. The plant will be designed to serve the planned Mountain Shores Subdivision only, with room for future expansion to serve Allen' s and Kelley-Tiao' s developments as they are platted. Any other uses that have the potential for increasing hydraulic or organic loading beyond plant capacity will be subject to Board approval as well as the Weld County Subdivision approval procedures. Financial System Plant construction will be financed by the developer, and the cost will be added proportionately to lot prices as they are sold. Operation and maintenance costs will be paid by subdivision residents through sewer fees or Homeowner' s Association fees. Developed areas using the facility will be billed for service depending on their proportion of the total service area. The share of these costs assigned to unsold lots will be paid by the developer until the lots are sold. The fees will increase as the facility ages and operation and maintenance costs increase. .41 The Homeowner ' s Association or Sanitary District will have full responsibility for operation and maintenance of the treatment facility, lift station, and land application system. The Association will hire a certified operator to 3 3 I` ' A ES SUBDIVISIO \\ jnAPUCATION : { ii `.

However, since Longmont' s initial disapproval of the Mountain Shores plan, the City' s administration has changed to one with a more pro-growth attitude. The City may be more receptive to a request for sewer service within a few years. In addition, a proposed Hewlett-Packard facility in northeast Longmont will require a large sewer line. This line will bring sewer service much closer to the subdivisions. At that time, Longmont may permit Mountain Shores to tie to the new main. Effluent Quality The Water Quality Control Commission has not set standards for land applied treated wastewater. However, a 1977 1 memorandum from Mr. Frank Rozich lists some guidelines for crop and landscape irrigation using wastewater. These guidelines recommend secondary treatment, with effluent standards of BOD less than or equal to 30 mg/1, suspended solids less than or equal to 30 mg/1, and disinfection to below 200 fecal coliforms per 100 ml. The planned treatment plant will be designed to meet these guidelines. 1 Land Application Initially, wastewater will be applied to open space landscaping in the Mountain Shores Subdivision, with excess water being sent to the Allen and Kelley-Tiao parcels for crop irrigation. A pond for treated wastewater will provide storage during winter months and wet periods. To prepare for Longmont' s inability to provide sewer service when Allen and Kelley-Tian - parcels are being developed, another landowner, Mr. Felix DeBuse, has agreed to accept excess wastewater generated by the subdivisions. His property is shown on the area map in this report (E1/2, NW1/4, Sec. 29 ). • • • I , We the undersigned object to the building of a proposed Waste water treatment plant at Mountain Shore Subdivision , NE of Union Reservoir, as a health hazard and eyesore for the surrounding area. i C� Lei/12 m gr�c 9„c�c , ,4s-ca L. /3775 7 ,1CA'j/...:/). �/Cr, Ce1 C 7/ 7; /1?"--;5. t <E 701 ,E zy,v,i j C�%A)- 771 -S� aCs � e . pc, wcP3 Le,//T co 176- . :n .-. , - r ,.

Notice of these meetings is appreciated and Union Reservoir Company requests that it be advised in the future of any meetings that may be held with regard to Mountain Shores Subdivision. At its most recent meeting of the Board of Directors , the Directors determined that if approval is granted on the sewage treatment facility without prior approval of the system by Union Reservoir Company that the County will be held liable for any damage caused by effluent discharged into the reservoir, including damage from loss of recreational lease currently in effect on the reservoir.

Box 449 Greeley, Colorado 80632 March 26 , 1982 Weld County Commissioners Weld County Complex Greeley, Colorado 80631 Gentlemen: It is understood the Board of County Commissioners of Weld County is again considering a sewage system which could adversely affect the Union Reservoir. No notice has been given Union Reservoir Company of this further consideration. Union Reservoir Company is quite concerned about the possible approval of sewage treatment facility proposed for a 280-unit sub- division by Calkins Lake II , Ltd. Partnership - Mountain Shores Subdivision. As stated in previous letters and meetings before the Commissioners , the proposed subdivision is north of Union Reservoir and any discharge of effluent into Union Reservoir would cause considerable damage to Union Reservoir Company. The Company receives almost all of its income from a recreational lease of the reservoir and the Company fears that even in the event that there might possibly be any discharge of effluent into the reservoir that the lease will be terminated . Loss of the lease would mean that the stockholders would be paying higher assessments for the irrigation water . There are also a greater number of people provided recreation by the reservoir than would be benefitted from the development of Mountain Shores Subdivision. Union Reservoir Company urges that any sewage treatment system for the subdivision not be approved until it has been presented to the Company and received the Company' s approval. The Company will not withhold its approval arbitrarily, but feels it must protect its interests and those of its stockholders in this matter since it can have such great influence on the Company.

RE: Site Application for Construction of Sewage Treatment Plant, Mountain Shores Subdivision, Weld County, Colorado. Regarding the above captioned proposal , the City of Longmont responds with the following comments and recommendations. The City has consistently opposed major subdivision proposals in the area of Union Reservoir based upon the planning policies exemplified in the Weld County Comprehensive Plan, these specifically being: a) New residential developments which are not clearly connected to and served by municipal utilities and services shall be dis- couraged; and b) Proposals for new residential development adjoining existing municipalities shall be encouraged so long as they conform to the desires of the towns as expressed in their comprehensive plans. The St. Vrain Valley Plan designates the area of the proposed treatment plant and development as "Agricultural ," as does the Weld County Comprehensive Plan Future Land Use Map. It should be noted that within the City's Prime Urbanized Area (urban service area) , the City has committed to serving over time approximately 16,000 additional dwelling units - enough to double the current population of 43,000 persons. Finally with respect to the Hewlett-Packard proposal , the site between Pace Street and County Line Road has been conditionally annexed to the City and is still under Boulder County jurisdiction. The site will be formally annexed when the conditions of an agreement between H-P and the City have been satisfied. According to information from H-P, construction of their first phase will not be completed until December of 1985. While the City will eventually serve the site with a major trunk sewer line, it is currently possible for the first phase to be served from existing capacity in lines west of the site. The exact timing for construction at the major trunk sewer line is still an unknown. With these factors in mind, the Sewage Treatment Plant proposal was brought before the City' s Long Range Planning Commission and Planning and Zoning Commission At their meeting of March 11 , 1982, the Long Range Planning Commission unanimously approved a motion to recommend denial of the proposed sewage treatment plant at this time and to re-evaluate the situation once the 48" trunk sewer line running between Pace Road and County Line Road is completed. Likewise, at their meeting of March 17, 1982, the Planning and Zoning Commission unanimously approved a motion to accept and adopt the recommendation of the Long Range Planning Commission. • • Sewage Treatment Plant, Mountain Shores Subdivision , Weld County March 22, 1982 Page 2 The City also has general concerns about the ability of a homeowners association to provide adequate financing for maintenance purposes. Another option, the use of a sanitation district raises similar concerns along with potential conflicts to future expansion of the City. Attached you will find a memo from the Water and Sewer Department of the City which raises engineering concerns. Thank you for the opportunity to comment on this matter.

D. Lawson , Director, Water & Sewer Utilities FROM: Jean Ray, Civil Engineer C� DATE: March 9, 1982 RE: Site Application for Construction of Sewage Treatment Plant Mountain Shores Subdivision, Weld County, Colorado The proposed Mountain Shores Subdivision sewage disposal system is an extended aeration wastewater treatment facility to be located on the adjacent Kelly-Tiao property. Subsequent effluent disposal through land application on the subdivision open space land and on the 80- acre Kelly-Tiao property has been arranged. Provisions for plant expansion and for alternate land irrigation sites have been made in the event that Kelly-Tiao develops . Wastewater treat- ment through the City of Longmont, however, is the preferred alternative to future plant expansion. Several concerns which require further consideration include: 1 . Odor problems associated with the treatment unit, storage ponds, and land irrigation. 2. Health considerations associated with storage ponds and with irrigating open space subdivision land. 3. Seasonal problems associated with sewage treatment and land application. 4. Adequate storage for winter months and for downtime. 5. Soil permeability and the soil 's ability to accept the proposed irrigation application rate. 6. Long-term availability of land for irrigation with Wastewater Treatment Plant effluent. 7. Long-term management and financial considerations associated with the treatment facility. 8. The proximity of the sewage disposal system to homeowners. JR/rh 1100 S.
