NOTARY /Ay Commission Expires June 9,2003 MY COMMISSION EXPIRES - Response to Department of Planning Services & Referral Agency Sketch Plan Comments The following statements are intended to specifically address each of the staff and referral agency Sketch Plan review comments as outlined in the February 29, 2000 letter from the Weld County Department of Planning Services. Adherence to the Comprehensive Plan Goals and Policies A.Goal 1 — "Preserve prime farmland for agricultural purposes which foster the economic health and continuance of agriculture." — The Weld County Comprehensive Plan indicates in A.Goal 9 that 80 acres is considered the minimum lot size needed to retain a viable farming operation. This parcel is only 32.5 acres, including the existing residence on proposed Lo.` I, and contains a mixture of prime and non prime soils according to the Important Farmlands of Weld County map. Due to the size and configuration of the parcel, as well as the mix of soils, the parcel is not a viable solely as a farming operation. A.Goal 3 — "Discourage urban-scale residential, commercial and industrial development which is not located adjacent to existing incorporated municipalities" — The Sketch Plan comments acknowledge that this proposal complies with A.Goal 3. A.Policy 6 — "Weld County will encourage developers and utility providers to deliver urban services prior to development." -- Referral comments from the Weld County Department of Public Health and Environment dated January 10, 2000, indicate that "The application has satisfied PUD Ordinance No. 197 in regard to water and sewer service. " A "will-serve' letter from the North Weld County Water District (NWCWD) has been submitted with the Sketch P/an application materials. An existing NWCWD tap currently serves the existing residence on proposed Lot 1. Appropriate permits will be obtained and the proposed septic systems will be installed in accordance with Weld County requirements for Individual Sewage Disposal Systems. P.Goal 2 — "Require adequate facilities and services to assure the health, safety, and general welfare of the present and future residents of Weld County." - Referral comments from the Eaton Fire Protection District dated January 28, 2000, indicate that a fire hydrant or other access to water is necessary. The plan has been amended to include afire hydrant. The Eaton School District RE-2 referral dated January 11, 2000, indicates that the District requires either a dedication of land or a payment of cash-in-lieu of land in order to offset the impact of development on the District. Judging by the District's required acreage for a school site (10—45 acres) and the relatively small acreage of the subject parcel, it is anticipated that a cash in lieu of land agreement will be the District's preferred alternative. A cash-in-lieu fee may be paid at the time of application for individual building permits. 1 In addition to the aforementioned Sections of the Weld County Comprehensive Plan, this proposal also complies with the Planned Unit Development Goals and Policies of the Comprehensive Plan. These Goals and Policies are specifically addressed in the Specific Development Guide included in this submittal. This proposal is in complete compliance with the Weld County Comprehensive Plan. STREET/UTILITY/ACCESS STANDARDS: T,Policy 4.2 — "The County should review and determine that all road, street, or highway facilities are adequate in width, structural capacity, and classification to meet the traffic demands of any land development. The County will, as a condition of land development, require improvement of roads, street, or highway facilities when dictated by traffic demand and land development patterns." - The roadways within this proposal are designed to meet and exceed the minimum requirements of Section 10 of the Weld County Subdivision Ordinance. The roadway construction and improvements have been provided within the preliminary on-site improvements agreement. Additionally, due to the minimal traffic impact, the Weld County Public Works Department has determined that a traffic study is not necessary. After review and comment by Public Works, the plat will be amended to include the interior road cross-section including width and depth of roadway, type of surface, right-of-way and cul-de-sac radius, in accordance with the standards of Section 10, Design Standards of the Weld County Subdivision Ordinance. The referral dated February 7, 2000,from the Weld County Public Works Department proposes to increase the length of the roadway, as well as add an additional turn-around or stub to an adjacent property. However, due to the proposed uses of the site and the length of the cul-de-sac as designed an additional turn-around or stub to adjacent properties should not be necessary. Section 2.6 of the PUD Ordinance #197 — "The Design Standards and Improvement Agreements of Section 10, 12 and 13 of the Subdivision Ordinance shall be utilized when applicable to the PUD Final Plan review and development." - The plat delineates utility easements in accordance with Section 10.6 of the Weld County Subdivision Ordinance. The final design of the utility easements will be at the Final Plan stage of the PUD process. OPEN SPACE/LANDSCAPING: Section 2.5 & PUD.Policy 4.2 — These sections of the PUD Ordinance #197 and Comprehensive Plan define common open space. Section 6.3.5.2.7 of PUD Ordinance #197 requires 15% common open space for all PUD's containing a residential element. This PUD application proposes 7.5 acres of common open space contiguous to the five PUD Estate zoned lots, or 23% of the total acreage of the PUD. Each lot has been designed to have common access from the perimeter open space, as well as from the cul-de-sac:. 2 The applicant does wish to reserve the ability for the future homeowner's association to construct some common use structures such as a barn or corrals in the common open space. Although the construction of structures in the open space may reduce the overall amount of open space by an insignificant amount, the uses of a barn and corrals is consistent with the non- urban, agricultural nature of the proposal. No buildings are proposed for the open space at this time, however, any potential structures would be constructed in a location that would not hinder the ability to continue irrigation of the pasture. Additionally, the proposal greatly exceeds the minimum open space requirement at 23% and the construction of such structures will not reduce the open space to below the required 15% minimum. Therefore, this proposal meets the definition of common open space as defined by Section' 2..5 of the PUD Ordinance #197 and PUD.Policy 4.2 of the Weld County Comprehensive Plan, while also exceeding the requirements of Section 6.3.5.2. 7 PUD.Policy 4.3 — "The developer should provide for perpetual maintenance of all commonly shared land and facilities. Weld County should not bear the expense or responsibility of maintenance for any commonly shared land or facilities within the planned unit development." - The common open space will be owned and maintained by the homeowner's association. Perpetual maintenance of all commonly owned areas and facilities will be specifically addressed in the homeowners association covenants. USES/BULK REQUIREMENTS/COMPATIBILITY OF USES: Section 2.3 — "Bulk Requirements — The normal Bulk Requirements for minimum setback, minimum offset, minimum lot size, minimum lot area per structure, maximum height of buildings, and lot coverage may be varied as specified in a PUD Final Plan." — No variances from the normal Bulk Requirements are contemplated at this time. Any proposed variations will be specified in the PUD Final Plan as required by Section 2.3. OG.Policy 1.1 -- "New planned unit developments or subdivisions should be planned to take into account current and future oil and gas drilling activity to the extent oil and gas development can reasonably be anticipated." — There are no existing oil and gas facilities located within the proposed PUD. To the applicant's knowledge there are no know commercial mineral deposits. A.Goal 7 and A.Policy 7 — The Weld County "Right to Farm" covenant will be placed on the plat and incorporated into the Ponderosa Estates subdivision covenants. DESIGN STANDARDS/IMPROVEMENTSAGREEMENT/SUBDIVISION IMPROVEMENTS: Section 12 — A preliminary improvements agreement addressing road construction and maintenance, open space landscaping and maintenance, utility extension and signage has been 3 submitted with the Sketch Plan application. The proposed improvements have been designea to meet or exceed Weld County standards. ENVIRONMENTAL CRITERIA: The majority of the concerns outlined in the Colorado Geological Survey's referral letter of January 10, 2000 pertain to soil settlement and foundation design. The soils information contained in the Geologic Engineering Report prepared by Terracon and recommendations in the Colorado Geological Survey referral will be utilized during development of the site Additionally,foundations for principal dwellings and/or structural steel accessory buildings will be engineered as required by the Weld County Department of Building Inspection. The Colorado Geological Survey's referral letter states, "In summary, there are no geologic conditions present that would preclude development but the subsurface soils should he evaluated so that the appropriate foundation designs are used " In accordance with the Weld County Public Works Department referral dated February 7, 201)0. a drainage plan is included in this PUD Change of Zone application. SUMMARY: The responses to the Sketch Plan Comments are intended to address the concerns that Weld County staff and referral agencies expressed in the review of the Sketch Plan application. Minor changes to the design as delineated on the new drawings and new reports should address cr11 the concerns that were listed. As is encouraged in Section 1.8 of the Planned Unit Development Ordinance #197, this propoaal promotes "the most efficient use of the land" as it is no longer feasible to continue to depend solely on farm production on the site due to the mixture of soil quality and size of the parse/. This PUD application is consistent with the goals and policies of the Weld County Comprehensive Plan as it proposes a non-urban scale development, which meets and exceeds the established requirements of the Weld County Subdivision, Zoning and Planned Unit Development Ordinances. 4 Specific Development Guide Ponderosa Estates PUD Section 1.1 of the Weld County PUD Ordinance #197 states "Encourage innovations in residential, commercial and industrial development so that the growing demands of the population may be met by greater variety in type, design and layout of buildings and by the conservation and more efficient use of open space in the development": This proposal addresses the growing demand for this type of residential opportunity, while at the same time achieving several goals of the Weld County Comprehensive plan including preservation of open space The general concept of this proposal is to create a five lot Planned Unit Development (PUD) that consists of five PUD Estate zoned lots averaging 4.55 acres per lot and 754 acres of common open space, or 23% of the total acreage. The proposal is a non-urban scale development as defined by Section 2.13 of the Weld County PUD Ordinance #197 and, as such, specifically, conforms to the Weld County standards and requirements for such non-urban developments. It is the intent of the applicant to create a subdivision that provides single-family residential lots while preserving a large amount of common open pace. The proposed land uses include single-family residential uses, passive and active open space, recreational opportunities for the property owners and continued agricultural production. The architectural style of the residential structures will be left to the discretion of the individual lot owners with standard limitations that will he specifically outlined in the covenants. The structures within the PUD will include single- family dwellings and accessory structures, which will adhere to the setback, offset and other applicable requirements of the Weld County Zoning Ordinance. This proposal is compatible with the surrounding land-uses, architectural style, character and zoning. The applicant wishes to establish a small, non-urban neighborhood consisting of residential and agricultural uses, which are consistent and compatible with the uses on surrounding properties. This application proposes to utilize the Specific Development Guide option as outlined in Section 6.2.1 of the Weld County PUD Ordinance #197. The following information is intended to address the eight major components of the PUD Development as outlined in Section 6.3 of the aforementioned ordinance. 6.3.1 Component One- Environmental Impacts: 6.3.1.2.1.1 - Noise and Vibration 6.3.1.2.1.2- Smoke, Dust and Odors 6.3.1.2.1.3—Heat, Light and Glare 6.3.1.2.1.4— Visual/Aesthetic Impacts 6.3.1.2.1.5—Electrical Interference 6.3.1.2.1.6—Water Pollution This proposed residential uses and continuation of existing agricultural uses should not have any negative impacts to the above listed environmental concerns on this property or on adjacent properties. In a referral response dated January 10, 2000, the Weld County Department of Public Health and Environment indicated that the initial impact plan included in the Sketch Plan submittal "...adequately addresses all potential impacts as required by section 4.2.5.14 of the PUD Ordinance. " Additionally, appropriate measures to mitigate wry potential construction impacts will be utilized during all phases of construction. The applicant is willing to address any specific concerns that staff or referral agencies may have pertaining to the listed environmental impacts. 6.3.1.2.1.7—Waste Water Disposal This proposal addresses the wastewater disposal on the site through the use of individua; sewage disposal (septic) systems. The Weld County Department of Public Health and Environment indicated in its referral response that "The application has satisfied PUD Ordinance No. 197 in regard to water and sewer service. " 6.3.1.2.1.8—Wetland Removal This proposal does not remove any existing wetlands. 6.3.1.2.1.9--Erosion and Sedimentation 6.3.1.2.1.10—Excavating, Filling and Grading 6.3.1.2.1.11 —Drilling, Ditching and Dredging The design of the proposed PUD requires minimal grading on the site. The proposea access is already existing to serve the existing residence on Lot 1. There will not be any drilling or dredging on the property. Erosion will be kept to a minimum based on the existing grade of the site and the general layout of the lots and open space. Additionally, effective erosion and sediment control measures will be utilized during all phases of construction. It is not anticipated that drilling will occur on this site, however a possible future drill site has been located at the northwest corner of the property. 6.3.1.2.1.12 - Air Pollution 6.3.1.2.1.13—Solid Waste 6.3.1.2.1.14—Wildlife Removal 6.3.1.2.1.15—Natural Vegetation Removal This proposal does not have a negative impact to the above listed environmental issues. The addition of plant buffers in the common open space provided in this proposal will ensure that vegetative cover remains protected into the future for wildlife in the area. 6.3.1.2.1.16—Radiation/Radioactive Material To the applicant's knowledge, there are no radioactive materials located on this site. 2 6.3.1.2.1.17 — Drinking Water Source The proposed potable water source for this development is water taps from the North Weld County Water District. Section 6.3.2.2.1.9 of the Weld County PUD Ordinance 4197 requires "A description of the water source and system and a statement from the representative of the provider of the water system which demonstrates that the water supply quality and quantity is sufficient to meet the requirements of the USES within the PUT) Zone District. " Included in the application materials is a "Service Agreement' with North Weld County Water District. A North Weld County Water District tar currently serves the existing residence on Lot 1. Additionally, the Weld Count} Department of Public Health and Environment indicated in its Sketch Plan retina response that "The application has satisfied HID Ordinance No. 197 in regard to water and sewer service. " 6.3.1.2.1.18— Traffic Impacts Due to the non-urban nature of this proposal there should be very little impact to traffic of the area. The February 7, 2000 Sketch Plan referral from the Weld County Public Works Department indicates that a Traffic Impact Analysis is not required for this proposal. 6.3.2 Component Two— Service Provision Impacts: 6.3.2.2.1.1 — Schools As stated in the applicant's response to referral agency Sketch Plan comments, the Eaton School District RE-2 referral dated January 11, 2000, indicates that the District requires either a dedication of land or a payment of cash-in-lieu of Iced in order to offset the impact of development on the District. Judging by the District's required acreage fkr a school site (10 — 45 acres) and the relatively small acreage of the subject parcel, it is anticipated that a cash in lieu of land agreement will be the District's preferrea alternative. A cash-in-lieu fee may be paid at the time of application for individual building permits. 6.3.2.2.1.2— Law Enforcement 6.3.2.2.1.3—Fire Protection 6.3.2.2.1.4—Ambulance This proposal should have a minimal impact to the above service providers. Referral comments from the Eaton Fire Protection District dated January 28, 2000, indicate that a fire hydrant or other access to water is necessary. The plan has been modified to include the proposed location of a hydrant for fire protection. The final location of the hydrant will be based on direction from the Eaton Fire Protection District. The review of this proposal by the public service providers will ensure that impacts are mitigated, if necessary. 3 6.3.2.2.1.5—Transportation 6.3.2.2.1.6--Traffic Impact Analysis The roadways within this proposal are designed to meet and exceed the minimum requirements of Section 10 of the Weld County Subdivision Ordinance and the Public Works Department The roadway construction and materials are listed within the preliminary on-site improvements agreement, which was included in the Sketch Plan submittal. The roadway is designed to be a 20' wide gravel road with 4' gravel shoulders. Additionally, as previously stated in Section 6.3.1.2.1.18 - Traffic Impacts, due to the non-urban nature of this proposal there should be very little impact to traffic of the area. The February 7, 2000 Sketch Plan referral from the Weld County Public Works Department indicates that a Traffic Impact Analysis is not required for this proposal. 6.3.2.2.1.7— Storm Drainage The impact to existing storm drainage patterns should be minimal and is addressed in the enclosed preliminary drainage plan as required by the Weld County Public Works Department referral dated February 7, 2000. 6.3.2.2.1.8-.Utility Provisions 6.3.2.2.1.9--Water Provisions As previously stated, utilities are available for this proposal. The proposed potable water source for this development is water taps from the North Weld County Water District Section 6.3.2.2.1.9 of the Weld County PUD Ordinance #197 requires "A description of the water source and system and a statement from the representative of the provider of the water system which demonstrates that the water supply quality and quantity is sufficient to meet the requirements of the USES within the PUD Zone District. " included in the application materials is a "Water Service Agreement" with North Weld County Water District. A North Weld County Water District tap currently serves the existing residence on Lot 1. Additionally, the Weld County Department of Public Health and Environment indicated in its Sketch Plan referral response, that "The application has satisfied PUD Ordinance No. 197 in regard to water and sewer service. " 6.3.2.2.1.10— Sewage Disposal Provisions As previously stated, the individual lots will utilize individual sewage disposal (septic) systems for sewage disposal. All of the lot sizes exceed the requirements of the Weld County Health Department. A septic permit will be applied for with each individual residential building permit. Additionally, the Weld County Department of Public Health and Environment indicated in its referral response that "the application has satisfied PUD Ordinance No. 197 in regard to water and sewer service. " 4 6.3.3 Component Three—Landscaping Elements: 6.3.3.2.2— Landscape Plan 6.3.3.2.3— Treatment, Buffering and/or Screening Included in the application materials is a concept landscape plan that delineates the proposed landscape elements within the proposal. The proposed landscaping is placed to enhance the property while protecting the views of the surrounding neighbors. No screening is necessary on this site. The open space and proposed landscaping on the north side of the property will also act as a buffer between the residential uses of this proposal and the existing agricultural uses to the north. 6.3.3.2.4-Maintenance Schedule for Landscaping Elements 6.3.3.2.5—On-site Improvements Agreement 6.3.3.2.6—Evidence of Water Any dead or dying material will be replaced at the earliest planting time possible. 17w plant species chosen are drought tolerant and will do very well with minimal irrigation once established The proposed plant materials will be irrigated as necessary by truck. The preliminary on-site improvements agreement includes the landscaping elements and is part of this submittal package. A final on-site improvements agreement will be included in the Final Plan submittal. 6.3.4 Component Four—Site Design: 6.3.4.2.1.1 --Unique Features There are not features unique only to this property. Private irrigation ditches are located along the north and east sides of the property. 6.3.4.2.1.2—Rezoning Consistent with Comprehensive Plan The Weld County Comprehensive Plan directs the County to provide a process to subdivide agriculturally zoned property. This application proposes a five lot, non-urban scale subdivision that has minimal impact on the service providers of the area and is consistent with the existing surrounding land uses. This proposal allows for efficient and orderly development of the area and the protection of passive open space for the existing and future citizens of Weld County The Weld County Comprehensive Plan sets forth criterion for review of applications for the division of land which is zoned agricultural, including soil classifications, agricultural productiveness of the site, feasibility for continued farm production on the site and utilization of existing housing. The subject parcel is only 32.5 acres in size and is primarily classified as "irrigated land non prime" on the Important Farmlands of Weld County map. The Weld County Comprehensive Plan indicates in A.Goal 9 that 80 acres is considered the minimum lot size needed to retain a viable farming operation. At less than half of 80 acres with non prime soils, the applicant contends that it is no longer feasible to continue to depend solely on farm production on the subject parcel. However, 5 this proposal does strive to maintain agricultural production on the parcel through the use of the existing pasture to he preserved as common open space and the ability for continued pasture use on each lot. It is the intent of the property owners to comply with the Weld County Comprehensive Plan, Weld County Zoning Ordinance, Weld County Subdivision Ordinance, and Planned Unit Development Ordinance 197. 6.3.4.2.1.3— Compatibility of uses allowed within the PUD Zone District This application proposes residential and agricultural land uses, which are listed as a Use Allowed by Right in Weld County's Estate zone district. Section 35.3.1 of the Weld County Zoning Ordinance addresses compatibility in a Planned Unit Development District, stating "The density, design, and location of land uses within and adjoining a Planned Unit Development District shall be designed to be compatible with other uses within and adjoining the PUD District Compatibility of uses shall be determined by evaluating the general uses, building height, setback, offset, size, density, traffic, dust, noise, harmony, character, landscape, screening, health, safety, and welfare. " This proposal meets and, in most cases, greatly exceeds the Weld County standards for all of these design elements. Compatibility will be further addressed by including Weld County's "Right to Farm" covenant on the plat 6.3.4.2.1.4—Compatibility with Surrounding Land Uses Weld County Comprehensive Plan PUD.Policy 4.1 states, "The design of a planned unit development should ensure compatibility and harmony with existing and planned uses on adjacent properties and within the planned unit development " The surrounding land uses include agricultural and residential uses similar to the uses proposed by this application. The proposed design for five PUD Estate lots and common open space takes into consideration the existing uses of the surrounding properties, as well as, the site advantages and limitations. The design of the open space and proposed landscaping on the north side of the property will act as a buffer between the residential uses of this proposal and the existing agricultural uses to the north. The architecture within this proposal will be compatible with structures of the surrounding area. As previously stated, this proposal does not take "prime"farmland out of production or limit the ability for continued agricultural production on this site or adjacent properties. Compatibility will be further protected by including Weld County's "Right to Farm" covenant on the plat and within the covenants. PUD.Policy 4.1 goes on to list several design elements for consideration such as density, street design, traffic impacts, open space and landscaping This proposal meets and, in most cases, greatly exceeds the Weld County standards for these design elements. 6.3.4.2.1.5— Overlay Districts This proposal is not located within any of the overlay districts, as identified by the maps officially adopted by Weld County. 6 6.3.5 Component Five—Common Open Space: This proposal exceeds the requirements for open space and will maintain compliance with, Sections 6.3.5.2.1 through 6.3.5.2.5 of the Weld County Planned Unit Developmem Ordinance #197. 6.3.5.2.7— 15% Common Open Space Minimum This proposal provides for 7.54 acres of common open space, which equals 23% of the total project acreage. This proposal exceeds the required 15% open space by 8% or 2.6 acres. 6.3.5.3.2—Ownership of Common Open Space 6.3.5.3.2.1 — Construction of Open Space 6.3.5.3.2.2— On-Site Improvements Agreement The common open space will be owned and maintained by the homeowners association. The construction of the open space amenities is minimal and is mainly vegetation. A preliminary on-site improvements agreement, which addresses Sketch Plan referral comments is included as a part of this submittal and includes the proposed improvements to the common open space. The property owner wishes to reserve the ability for the future homeowner's association to build common use structures such as a barn or corrals in the common open space. The potential structures would be constructed in a location that would not hinder the ability to continue irrigation of the pasture and would include common access from the cul-de-sac or the perimeter open space. Due to the agricultural uses of the site and the low density, additional road improvements to access the common open space should not be required 6.3.6 Component Six— Signage: This proposal shall comply with the sign standards, as set forth in Sections 6.3.6.3 and 6.3.6.4 of the Weld County Planned Unit Development Ordinance #197. Signage will be incorporated into the landscape and will be limited to street and subdivision signage. 6.3.7 Component Seven—M.U.D. Impact: This proposal is not located within the M.U.D. Boundary, as delineated in the Weld County M.U.D. Ordinance or the Comprehensive Plan. There is no M.U.D. impact 6.3.8 Component Eight—Intergovernmental Agreement Impacts: This proposal is not located within any approved intergovernmental agreement boundaries. This proposal is not located within any designated Urban Growth Boundaries. 7 IMPROVEMENTS AGREEMENT ACCORDING POLICY REGARDING COLLATERAL FOR IMPROVEMENTS (PRIVATE ROAD MAINTENANCE) THIS AGREEMENT, made and entered into this day of by and between the County of Weld, State of Colorado, acting through its Board of County Commissioners, hereinafter called County", and Cecil Farms hereinafter called "Applicant".

Boden G Registered Professional Engineer State of Colorado No. 30007 Introduction The Ponderosa Property is located in the southeast quarter of Section 1I, Township ( North, Range 66 West, Weld County, Colorado. More specifically, the site is located uh the north side of Weld County Road 70 roughly 1/2 mile east of Weld County Road 33 The development of this site consists of ultra low-density residential development of developed lots. Access to the proposed site is from WCR 70. Intent The intent of this report is to provide a drainage study in accordance with Section 10. 12 of the Weld County Subdivision Ordinance I73-E for the request for Change of Zohe concerning this property. Design Reference The City of Longmont Storm Drainage Criteria Manual (Based upon the Boulder Count, Storm Drainage Criteria Manual) provides the drainage design criteria for this report Since all basins are less than 100 acres in area, the Rational Method was used to calculate storm flows. The values for runoff coefficients C, and rainfall intensities I, were taken from the City of Longmont Storm Drainage Criteria Manual for the anticipated tuture land use. The 2-year and 5-year storm events were used for calculations involving the minor storm and the 100-year event was used for the major storm. The required detenti.ni pond volume was calculated using the Equation Detention Method with a release r to equal to the rate of the 5-year historic flow from that portion of the property bei u,.. developed. Existing Drainage Conditions Historically, this property drains generally from the north east to the south west and is split into 2 on-site drainage basins. The flow from Drainage Basin A sheet flows south west to the to the west property line. The flow from Drainage Basin B sheet flows south east from the south west property corner to WCR 70. The majority of the flows are collected in an existing culvert across WCR 70 and diverted into an existing drainage ditch that eventually drains into the Greeley Canal #2 along State Highway 392. Developed Drainage Conditions Drainage from the proposed developed area will be directed from each individual lot to the proposed access roadway borrow ditch along the west property line. These flows will be directed to a proposed detention pond at the south west property corner of Lot I and discharged to the existing culvert across WCR 70. Ultimately, these flows are di✓ened into an existing drainage ditch that drains into the Greeley Canal #2 along State High av 392. Release from the detention facility will be released at the historic 5-year rate for that portion of the property that will be developed 2 Conclusion The proposed development will not adversely affect the existing drainage patterns surrounding the site. Developed runoff from the property will be detained in a proposed detention pond and released at the historical 5-year rate of 4.6 cfs maximum. A cop\ of the historical drainage plan, proposed drainage plan, and drainage calculations follow for your review. 3 APPENDIX A 4 Drainage Calculations(Based upon Rational Method) PONDEROSA PUD(Change of Zone) Boden Engineering, LLC Longmont, Colorado By: Mike Boden, P.E 6/15/00 C Intensities Q(cfs) Basin ID j Point j Area (ac.) 2 year I 5 year 1100 year Flowlength (ft) I Ti I Tt I Tc 2 year J 5 year 1100 year 2 year I 5 year 1100 year HISTORIC A(2 Year) 30.82 0.05 1879 33 28 61 1.0 1.5 A(5 Year) 30.82 j 0.10 ' 1879 31 28 59 1.5 4.6 50 3.1 38.2 (1 --ea ) -. _. _ 30.82 0.40 1879 - 22. � 28 - -- - - -- -- --- '� A 100 Year)4 1 - � i B(2 Year) j 0.79 I 0.05 600 48 ' 7 55 1-1 j , 0.0 B(5 Year) ' 0.79 I 0.10 600 46 I 7 53 1.6 0.1 B(100 Year) 0 79 j 0.40 600. i 32 j 7 j 39 3.6 1.1 - DEVELOPED A I 30.8 030 0.35 0.60 1879_---; 20 I 2 I 2.8 T 5.3 18.5 302 980 B 0 8 0.30 0 35 0.60 600 13 2.5 3.5 6.5 0.6 1 0 3 1 Notes: 1.
