This letter is intended to clarify and address the issues identified as part of the PUD Sketch Plan review, as well as fulfill the response requirement for the upcoming P.U.D. Change of Zone application and review. The following responses summarize the comments of each agency that responded to the P.I.D. Sketch Plan Referral process: City of Greeley, referral dated 3/30/18 The City of Greeley Community Development and Planning department commented on the ecological significance area along the Greeley No.2 Canal, suggesting the applicant determine the wildlife habitat and native plantings that may be impacted by developing this area. The existing property is dryland pasture, historically used for livestock grazing, and does not contain any existing trees within the Greeley No. 2 ecological significance area. The (6) proposed lots that fall within this area have an average lot size of 3.46 acres, and the building envelopes for these lots are designed to be on the outer -most edge of this buffer. The proposed design will have little to no impact on wildlife habitat and native plantings. The property is located with the City of Greeley Long Range Expected Growth Area (LREGA) and if in the future, water and sewer services are requested to property, annexation would be required prior to providing services. We acknowledge this, and there are no current City utility services to the property. We have received intent to serve from North Weld County Water District and the proposed lots will be served by On -Site Wastewater Treatment Systems. Town of Severance, referral dated 4/6/18 The Town of Severance reviewed the Sketch Plan request and found no conflicts with their interests. . Town of Windsor, referral dated 3/16/18 The Town of Windsor reviewed the Sketch Plan request and found no conflicts with their interests. 4. School District RE -4, referral dated 3/16/18 Weld RE -4 School District has indicated land dedication is not feasible for this project and will require cash -in -lieu at $2,240 per lot. The applicant acknowledges this request and will coordinate with the School District for collection timeline. The School District has also requested a bus turnaround area at either entrance. We will incorporate a turnaround and design meeting school bus standards through coordination with Stephanie Watson. 5. Greeley #2 Ditch Company, referral dated 4/13/18 The Greeley #2 Greeley Ditch Company has requested a 35' operation and maintenance easement be designated on the Plat. We acknowledge this request and have incorporated into the proposed design. A stormwater agreement has also been requested, outlining allowable historical release amounts. Ongoing coordination efforts and correspondence with Dale Trowbridge are included with the Change of Zone submittal. 6. Colorado Geological Survey, referral dated 4/16 18 The Colorado Geological Survey reviewed the Sketch Plan and has no objection to approval of the 16 -lot PUD Sketch Plan. Weld County Sheriffs office, referral dated 4/4/18 The Weld County Sheriffs Office reviewed the Sketch Plan and found no conflicts with their interests. 8.

Colorado Division of Water Resources, referral dated 4/4/18 The Colorado Division of Water Resources reviewed the Sketch Plan and considers the North Weld County Water District to be a reliable water source and the project will not cause material injury to decreed water rights. Ongoing coordination with Greeley #2 Ditch Company (per the above) and stormwater agreement will also satisfy any concerns with historical release rates. 11. Colorado Department of Transportation, referral dated 3/22/18 CDOT reviewed the Sketch Plan and commented on potential impacts on the WCR 27/5,1392 intersection and associated traffic volumes. If traffic volumes are increased by more than 20%, a new access permit would be required and auxiliary lane construction be considered. Sean Kellar, the traffic engineer for the project, provided analysis for potential impacts at WCR27/5H392 via email correspondence dated 7/11/18 with Gloria Hice-Idler of Rocksol Consulting. He concluded the proposed development would cause less than a 2% increase to traffic volumes and would not warrant auxiliary lanes at WCR7/SH32. The additional 75' for future ROW at SH392 has also been accounted for and incorporated into the design. 12. Weld County Department of Public Works, referral dated 4/13/18 Weld County Department of Public Works reviewed the Sketch Plan and commented on the following items: • North Access - Concerns with spacing criteria and alignment with existing access on west side of CR27.

We have designed the north access to align with the north driveway across the street on CR27 (CR25.75) — see attached image with red line illustrating location. Can you please provide clarification to the nature of your comment for both spacing criteria and alignment? The 2017 Functional Classification Map shows the existing CR 27 (CR25.75) as a gravel local, which would require 135' intersection spacing (per Table 1.04.2 Technical Design Criteria).

Site Location The project site is located within the Northeast 1/4 of Section 19, Township 6 North, Range 66 West of the 6th P.M., County of Weld, State of Colorado. More specifically, the site is located on the east side of Weld County Road 27 between Highway 392 and Weld County Road 66. Please refer to the Vicinity Map located in Appendix A. The area surrounding the project site is sparsely developed. The site is surrounded by residential/agricultural properties. The Greeley #2 Ditch, managed by the New Cache Ditch Company, runs along the south and east sides of the site, and will be the receiving water for site runoff. B. Site Description The Lone Star Estates site is approximately 59.2 acres and has historically been used for agricultural purposes. Existing ground cover primarily includes native vegetation. The northern portion of the site, approximately 43.5 acres, drains to the east at a slope of approximately 1-3 percent. The remaining 15.7 acres drains south at a slope of approximately 1-3 percent. According to the NRCS soils map survey, the native soils consist of Kim Loam, which is a Type "A" soil. These soils have a moderate to high infiltration rate (low runoff potential) when thoroughly wet. C. Proposed Project Description The site will consist of the future development of approximately sixteen (16) residential lots with a minimum area of two (2) acres. Primary construction will include the construction of a residential access road and the construction of two on -site detention ponds. II. DRAINAGE BASINS AND SYSTEM A. Major Basin Description The proposed site is not located within any major drainage basin according to The Weld County Master Drainage Plan and does not identify any major drainage improvements for this area. The Lone Star Estates site is not located in any floodways or flood prone areas. The site is located in FEMA FIRM Map Panels 08123 1510E and 081230 1502E. There is no FIRM PAGE 4 Map for 0 123C1502E because there are no flood hazard areas within its limit. The property is located entirely within Flood Hazard Zone X indicating an area of minimal flooding. A copy of the FEMA FIRM Map is included within the appendix. B. Sub -Basin Description The developed site is delineated into two sub -basins. Sub -basin Pi, (43.5 acres), is comprised of the northern portion of the site. The basin consists of residential lots, a portion of the access road, landscaping, and a detention pond. Runoff will generally follow historic drainage patterns and flow east into a proposed detention pond. The proposed detention pond will require roughly 117,000 cubic feet (2.76 ac -ft) of volume to accommodate the developed runoff of 37.1 cfs. The pond will release at the 10 -year historic rate of 1.92 cfs. Sub -basin P2, (15.7 acres), is comprised of the southern portion of the site. The basin consists of residential lots, a portion of the access road, landscaping, and a detention pond. Runoff will generally follow historic drainage patterns and flow south into a proposed detention pond. The proposed detention pond will require roughly 43,500 cubic feet (1.00 ac -ft) of volume to accommodate the developed runoff of 19.35 cfs. The pond will release at the 10 -year historic rate of 0.81 cfs. III. DRAINAGE CRITERIA A. Regulations Drainage design criteria specified in the Weld County Drainage Criteria found in the Weld County Engineering and Construction Criteria, the Urban Storm Drainage Criteria Manual, Volume 3 by the Urban Drainage and Flood Control District (UDFCD), and Design Criterial and Construction Specifications Storm Drainage Volume II have been referenced in the preparation of this study. B. Development Criteria Reference and Constraints The criteria used as the basis for analysis and design of stormwater management improvements for this site are those found in the references cited. To the knowledge of the author, there are no other capital drainage improvements planned for this portion of the site; aside from those referred to above, that would constrain or otherwise influence the design of the stormwater improvements for this site. C. Hydrological Criteria PAGE 5 Stormwater runoff from the respective sub -basin of the site is analyzed for storms with 10 - year and 100 -year return frequencies. Due to the relatively small aggregate area of the tributary drainage sub -basin (under 90 acres), the Rational Method was chosen for use in the design of the stormwater management improvements. The Rational Method provides that: Q CIA, where: = Design flow in cubic feet per second (cfs) C = Coefficient of runoff for the area under consideration I = Rainfall intensity for the design storm duration (in/br) A = Area of the drainage sub -basin under consideration (ac) Peak flows were calculated using the Rational Method for the 10 -year and 100 -year storm events. This software uses the local 1 -hour rainfall depth and Intensity -Duration -Frequency Curves Figure 3-1 and Extended Duration -Intensity -Frequency Tabulation Table 3-3 to calculate rainfall intensities as a function of the time of concentration. These values were obtained by the City of Greeley Design Criteria and Construction Specifications Storm Drainage Volume II, and can be found in the Appendix. The "C" values were taken from Table 6-5 Runoff coefficients. Percent imperviousness values were taken from Table 6-3, Recommended Percentage Imperviousness Values, USDCM (See Appendix). Soils of hydrologic soil type "A" dominate the site. The hydrologic basin parameters and runoff rates are included in the Appendices. The USDFCD software UD-BMP v3.03 and the Modified FAA Method, was used to calculate the size for the proposed detention pond. The proposed ponds were sized to detain the 100 -year storm and release at the 10 -year historic rate. Any flows greater than a 100 - year event will flow through a spillway/weir. The ultimate outfall for the detention ponds is the Greeley #2 Ditch. D. Hydraulic Criteria Within this development, all runoff will be conveyed on the surface, initially as sheet flow and subsequently as concentrated flow in swales. The assessment of required capacity and the sizing of the respective components of the drainage system are based on the anticipated runoff from the 100 -year storm event. E. Modifications of Criteria PAGE 6 There are no modifications or variances requested in connection with the design of the stormwater management for the Lone Star Estates site development. IV. CONCLUSIONS A. Compliance with Standards The drainage design for the Lone Star Estates site is in general compliance with the requirements of the Weld County Drainage Criteria. The criteria and recommendations of the Urban Storm Drainage Criteria Manual are also reflected in the design of the drainage system, as appropriate. B. Drainage Concept The drainage design for the Lone Star Estates site should be adequate to safely convey onsite flows through the development. Development of the site, as proposed, will have a beneficial impact on flood damage and water quality in downstream drainage facilities and drainage ways by delaying the initial discharge of runoff from the site such that sediments and other potential pollutants typically carried by this first flush are removed from the flow. The proposed drainage improvements cause no adverse impact to adjacent properties. V.

The drainage design shall meet the requirements of the Weld County Code and commonly accepted engineering practices and methodologies. A detention pond design (or other stormwater mitigation design) is appropriate for projects which have a potential to adversely affect downstream neighbors and public rights -of -way from changes in stormwater runoff as a result of the development project. The design engineer's role is to ensure adjacent property owners are not adversely affected by stormwater runoff created by development of the applicant's property.

At a 1"=100' scale the plat would take up several sheets. • All existing easements and right-of-way contiguous with the proposed PUD are shown in the zoning plat with reception numbers. If any additional information on easements and right-of-way associated with the property is needed they will be supplied upon request. • Included with this submittal are two emails to Dale Trowbridge at the New Cache La Poudre Irrigating Co.. A call and email were sent out on July 18, 2018 as well as a follow up email on July 30, 2018. Continued correspondence will continue until an easement agreement and stormwater agreement are finalized. If you have any questions or require additional information, please call Coffey Engineering at (970) 622-2095.

The proposed project's contributing traffic is much less than 20% to WCR 27/ SH 392. It's actually less than a 2% impact. Also, the development's site generated traffic does not warrant auxiliary lanes at MICR 27/SH 392. Based upon this information this project's site generated traffic does not trigger the need to address 1CR 27/H 392. Please feel free to let me know if you need anything further. Thanks! Respectfully, Sean Kellar, PE, PTOE 970.219.1602 skellar@ kellarengineering.com Figure 5: Site Generated Peak Hour Traffic S.H 392 VILE, r r esir 1 Site Access 1 Project Sitp a Site Access Legend Amipm Lone Estateisi T1S Page i0 Diana Aunyst ROM Sent To: Cc: Subject Diana, Hi -idler -CDOT, Gloria <gior .hive -idler@ te. ews Thursday, March 22, 201811:29 AM Diane Aungst Bilobran, Timothy PUDKIB- 2 - Lone Star Estates J'vo rovioitivod this pre sal and. offer the following: T.
