DATE: June 2, 1999 JUL ? c 1999 TO: Molly Orklid-Larson RECEIVED Tuttle-Applegate, Inc. FROM: Scott Toillion, Planning Specialist RE: Cash-in-lieu agreement - Riverside Thank you for providing the information on the Riverside proposal to the St. Vrain Valley School District and your willingness to help the District mitigate the impacts of development on the schools. After reviewing the site and the demographics the District would opt for the cash-in-lieu payment rather than a land dedication in this location. Enclosed is the standard agreement for Weld County development proposals which identifies the cash-in-lieu requirements. This development would be required to pay $427 per single-family unit and $196 per townhouse/condo unit prior to the issuance of a building permit. The note to be placed on the plat is as follows: "No building permit shall be issued by the County or any other local government for construction of any new residential dwelling within this plat until the applicant shall first supply the local government building department with a verified document signed by a representative of the St. Vrain Valley School District RE-1J which states that the obligation to pay a cash in-lieu of land dedication fee has been accomplished". This agreement will be revised and updated when you can provide the final development numbers, the legal description of the property and the appropriate signature block information. Once this agreement and its requirements are implemented the District concerns would be satisfied.

The referral was for a change in zone from agricultural to PUD. CCiS has no objection to the change in zone,but the following issues should be considered for the preliminary plat 1) Flood plain. A CT.OMR will be required from FEMA for any improvements within the 100-yr flood plain. This is discussed in the application report. 2) Oil and gas operations. If the oil wells and tanks are to remain on site after development, it should be made clear on the preliminary plat that service trucks will be using the development roads for access. 3) Bank stabilization. I saw no signs that the banks to the lakes were in the process of being undercut by wave action. However, the very coarse soil,composed of sand, gravel, and pebbles, is actively eroding and creating rills along the northwest bank of the eastern lake, The banks will be regraded in preparation for construction of the lakefront houses. A minimum 50-ft setback from the lakes should he observed for construction. The banks should be stabilized with native vegetation to prevent continued erosion that would lead to lot deterioration. It may be necesssary to use erosion control blankets locally,in addition to topsoil, to establish vegetation. 4) Soil. The subsurface material varies across the site from terrace gravels to bedrock of the Pierre Formation to windblown silts and clays. Soils derived from alluvial material should provide good subgrade for foundations. However, groundwater will be higher in areas underlain by gravels,and basement construction is not recommended without a detailed subsurface investigation and subsurface drainage system. The bedrock, depending on the degree of cementation, may he more difficult to excavate than surrounding materials. Also, the Pierre bedrock should be sampled during a preliminary subsurface investigation to determine the potential for swell. Swelling soils or bedrock will require special foundation and flour considerations. Likewise, the windblown silts and clays may have the potential for either swell or collapse behavior, and the subsurface investigation should characterize these soils as well.

As stated,groundwater is likely to he shallow beneath the flood plain sediments and is possibly also high in the farmed area. Currently, flood irrigation will obscure the natural groundwater conditions,but the proximity to drainages increases the likelihood of shallow groundwater, at least locally. The boring logs for the subsurface investigation should indicate the depth to groundwater both during drilling and also a specified time after drilling when the system has equilibrated_ A groundwater contour map should be prepared for use in planning and design. All homes should he designed with a perimeter drain to prevent the accumulation of subsurface water. Because the lot density is high, it may be necessary for the perimeter drains to discharge to an underdrain beneath the site. 6)Wetlands. The wetlands should be delineated by a qualified consultant. Any disturbance of these areas will require an approval of the Army Corps of Engineers, as stated in the application report. Tt is important.to remember that if wetland areas are filled, they still provide a preferred path for groundwater migration. Lots platted in these areas will likely be subject to wetness, at least seasonally, unless there is redirection or containment of subsurface flows by drains. In summary, the next stage of planning must include a preliminary subsurface investigation and should address the issues listed above. Please call me if there are any questions.

This request site is located east of and adjacent to I-25, south of and adjacent to WCR 28. The proposed site consists of 486.75 acres. This PUD proposal is for residential and commercial development. The residential development includes Lakefront &Equestrian Estates, large suburban& suburban lots, patio &town homes. Commercial development is proposed along the I-25 frontage road consisting of a gasoline station, video store, bakery, dry cleaners and professional offices. This proposed development is located within the flood hazard overlay district, however, no structures are proposed within the floodway. Mining has occurred in the floodplain,which has increased the ability of the over bank to handle more floodwater. A new floodplain boundary will be established with a Conditional Letter of Map revision submitted to FEMA and approval received prior to on-site construction. All wetlands should be preserved as much as possible. There is a weed management plan. The maximum building coverage will be determined at the time of the final plat. Approximately 47% of the proposed site will be open space. Water taps will be provided by the Little Thompson Water District. The St.Vrain Sanitation District (Saint San)will provide sanitary sewer service to the proposed development subject to conditions and rules &regulations of the St. Vain Sanitation District. Soils Found On Site: Achilles&Accents Deep poorly drained soils subject to flooding Kim Loam 3- S% Permeability is moderate, available water capacity is high, surface runoff is medium, and the erosion hazard is moderate. This soil has a good potential for urban&recreational development. This soil has a limited capacity for supporting a load. Septic tank absorption fields function properly, but community sewage systems should be provided if the population density increases Nelson Fine sandy loam 3- 9% Permeability is moderate to rapid, available water capacity is moderate, surface runoff is medium to rapid and the erosion hazard is moderate. Neither septic tank absorption fields nor sewage lagoons operate properly. Plantings of trees and shrubs may be difficult to establish. Site preparation for dwellings is more costly. This soil is suited to limited cropping. Potential native vegetation on this site is dominated by sand blue stem, sand reedgrass, and blue grama. Switchgrass, sideoats grama and western wheatgrass are also prominent. Pubescent wheatgrass & crested wheatgrass are also suitable for seeding. This soil does have good potential for recreational development such as camp, picnic areas and playgrounds. CONSERVATION-DEVELOPMENT-SELF-GOVERNMENT Tassel Fine Sandy Loam 5-20% Permeability is moderate to rapid, available water capacity low, surface runoff medium and erosion is moderate. Windbreak & environmental plantings are generally not suited to this soil. Production of vegetation on this treeless soil is low. Poor potential for urban development. Wiley-Colby Complex 1-3% Permeability is moderately slow, available water capacity is high, surface runoff is medium and the erosion hazard is moderate. Windbreaks and environmental plantings are generally well suited. The best suited trees; Rocky Mtn. Juniper, Eastern Red Cedar, Ponderosa Pine, Siberian Elm, Hackberry. Best suited shrubs; Skunkbush Sumac, Lilac, Siberian Peashrub and American Plum. Soils have fair to good potential for urban development. The weed management plan, if followed, will do a good job of controlling the noxious weeds. The Home Owners Association will need to be made aware of their responsibility to continue to control noxious weeds once the HOA takes control. I would suggest a Specific Site Review before any construction is started because of the diversity in the soil types. I would also suggest the lowest density of lots possible.

Water Division 1, Water District 4 Dear Mr. Patton: We have reviewed the above referenced proposal to subdivide 486.75 acres into 600 to 800 residential and commercial lots. The proposed water source is Little Thompson Water District (District) and a letter of commitment for service has been submitted for 125 lots in phase one and 512 lots in phase two. The District will supply treated water to the development. As a condition of activation of the taps, the applicant must transfer 1 unit of Colorado-Big Thompson (CBT) raw water (1 acre-foot per unit) for each lot, administered by the Northern Colorado Water Conservancy District, to Little Thompson Water District. No information is provided for the water use on commercial lots. Also, the District has not provided evidence that the applicant has transferred or will transfer the necessary shares of CBT water to the District. Based upon the above and pursuant to Section 30-28-136(1)(h)(II), it is our opinion that the District has not submitted sufficient evidence documenting that the proposed water supply can be provided without causing injury to existing water rights.

Planning DATE: August 9, 1999 ' C FROM: Trevor Jiricek, W.C. Department of Public Health anm Environment COLORADO SUBJECT: Z-528, RiverDance PUD/Mike Siegrist The Weld County Department of Public Health and Environment has reviewed this proposal. Our staff have also observed the proposed site. The application has satisfactorily addressed water and sewer service. Water will be provided by the Little Thompson Water District and sewer will be provided by the St. Vrain Sanitation District. The application materials also adequately address the potential environmental impacts as described in Section 6.3.1.2.1 of the PUD Ordinance. However, the fate of waste water from the Equestrian Center was not adequately addressed in this application. The Preliminary Drainage Report and Water Quality Management Plan states that"Runoff from the Equestrian Center could be conveyed to the unnamed swale in the eastern portion of the project." The Plan also goes on to state that the swale currently contains wetland vegetation and eventually discharges into St. Vrain Creek. The Colorado Water Quality Control Act prohibits discharges to waters of the State. Both surface water and groundwater are considered waters of the State. As a result,we are requesting that the applicant submit an updated waste water management plan, for the Equestrian Center, to be submitted with the Final Plan. I have enclosed a copy of the Confined Animal Feeding Operation Control Regulations for guidance in drafting the Plan. I would encourage the applicant to review Section 81.6 of these Regulations prior to formulating the plan. Additionally,due to the proposed density of the subdivision in close relation to the Equestrian Center we are requesting that the applicant also submit Plans concerning the minimization and management of flies, dust, and odors created from the Center. Our Department is concerned that the agricultural type uses may conflict with the nearby residents resulting in complaints, etc. We recommend that all of these Plans (waste water, fly, dust, and odor)be incoporated into the covenant or other legal document. The following are our preliminary recommended conditions for this application: 1) The applicant shall obtain water and sewer service from the Little Thompson Water District and the St. Vrain Sanitation District. 2) In the event that 5 or more acres are disturbed during the construction and development of this site, the applicant shall obtain a storm water discharge permit from the Water Quality Control Division of the Colorado Department of Public Health and the Environment. Silt fences shall IS EXHIBIT RiverDance PUD/Mike Siegrist August 9, 1999 Page 2 be maintained on the down gradient portion of the site during all parts of the construction phase of the project. 3) During development of the site, all land disturbance shall be conducted so that nuisance conditions are not created. If dust emissions create nuisance conditions, at the request of the Weld County Health Department, a fugitive dust control plan must be submitted. 4) In accordance with the Regulations of the Colorado Air Quality Control Commission any development that disturbs more than 5 acres of land must incorporate all available and practical methods which are technologically feasible and economically reasonable in order to minimize dust emissions. a) If land development creates more than a 25 acre contiguous disturbance, or exceeds 6 months induration, the responsible party shall prepare a fugitive dust control plan, submit an air pollution emissions notice, and apply for a permit from the Colorado Department of Public Health and Environment. 5) The "Right to Farm" covenant shall be placed on the plat. In the event inadequate waste water, fly, dust, or odor plans are submitted for the final plan, we will recommend conditions to address these issues. If you have any questions, please call me at extension 2209. tj/z528 MEMORANDUM TO: Ben Patton,'Planner DATE: July 30, 1999 lFROM: Donald Carroll, Engineering Administrator 121'WI DO SUBJECT: Z-528; River Dance PUD/Mike Siegrist COLORADO The Weld County Public Works Department has reviewed this proposal. This project falls primarily under the purview of the Weld County Mixed Use Development Area (MUD) Planned Unit Development Standards. Our comments and requirements are as follows: COMMENTS: The two major transportation items to be addressed in the change of zone are a traffic impact analysis and storm water drainage. A new traffic impact analysis for the River Dance Subdivision was included and has now been forwarded to our traffic analysis consultant, Felsburg, Holt, and Ullevig for their comments and review. A Preliminary Drainage Report and Water Quality Management Plan has been prepared by Tuttle Applegate. This has been reviewed and I have no conflict with this report. All drainage plans shall be stamped and signed by a professional engineer. REQUIREMENTS: WCR 28 is identified on the Mixed Use Development Structural Transportation Network Map 2.2 as a collector status/two-lane road with painted median. Current right-of-way is 60 feet. The developer is required to dedicate an additional 10 feet of right-of-way which will represent one half of the ultimate width requirement. A Road Improvements Agreement to construct one half of WCR 28 adjacent to the PUD shall be completed. A chemical dust suppressant shall be applied to the remaining gravel portion of WCR 28 west to the Frontage Road. An additional 10 feet of dedicated right-of-way adjacent to WCR 28 shall be placed on the plat. A typical cross section should reflect a collector/two-lane road with painted median. cc: Z-528 Planning Dept. planl5 MJG 02. 1999 RECEIVED EXHIBIT _ 4 "alrifiNi4 Its a-"" "rata T1 - „ • Hello
