If a question does not pertain to your use, please respond with "not applicable", with an explanation as to why the question is not applicable. 1 . Explain , in detail , the proposed use of the property. The site is located in the Southwest Quarter Of Section 18, Township 5 North, Range 67 West Of The 6th P.M., County Of Weld, State Of Colorado. The project is East of Weld County Road 13, South of Highway 34. Current the site contains existing residential wood framed structure and several small wood framed out buildings. The site historically been used for agricultural purposes, adjacent to the site is undeveloped parcels to the South, West and East, to the North of the site is an industrial development. The property will contain the following buildings; • Pet Memorial, Cremation and Euthanasia Center The pet memorial, cremation and euthanasia center is proposed to be a new structure on site that will be 2,520 sf building with a footprint of 60' x 42'. • RV storage facility We are proposing 5 new RV storage facilities at 200' x 50' (10,000 sf each) with 10 storage units each (50 total). Each unit will be 20' x 50' (1 ,000 sf each) with an overhead door at the entry side of each unit. The building will be pre engineered metal buildings with metal wall and roof panels. We will be providing emergency building mounted lighting only. There will be no outdoor RV storage provided on site. • Two Manufactured Homes The two new manufactured housing units will be 1 ,760 sf each. The property managers will be staying in the manufactured homes. We will also be keeping one of the existing structures currently on the site, this structure will be renovated into the business office of the site. • Three car garage A proposed three car garage with attached storm shelter will be on site. The garage and shelter will be a total of 1 , 152 sf and 48' x 24' . • Existing House The existing 2,562 square foot house with 435 square foot garage on site will be converted to a business office for the businesses. The site will contain a new paved driveway that will lead to the RV Storage building or parking spaces for the pet crematorium center. We will be providing 1 handicap stall and 4 standard size parking spaces for guests and employees. We will also have 3 spaces in the new garage structure. New landscaping is being proposed for the site to help screen the RV Storage building from Weld County Road 13. We also are proving a new 6' chain link fence around the RV Storage buildings for security purposes. The Southeast portion of the site will contain a detention pond area and a septic field. An RV dump station with a holding tank is being proposed on site adjacent to the RV buildings. Water Supply The water service provider to the site is Little Thompson Water District. We will be providing a new 1 " water line to the property replacing the 3/4" water line. The proposed use will have little to no impact on the demand for adequate water supply. The RV storage facility will generate little to no water use and the pet crematorium will also require very little water use. Economy The purposed use of the site will revitalize the property and increase the aesthetic value and commercial utility of the property promoting a commercial development through a sensitive agricultural use and function. The revitalization of the site will allow the owners to relocate and consolidate their businesses and still be apart of the community. Land Use The land use would reinvest and improve the economic vitality and appearance to the site, the site will be attractive, compatible commercial redevelopment that is environmentally sound and designed to be functional and attractive for the intended use. 2. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 22 of the Comprehensive Plan. This proposal is consistent with the intent and falls within the requirements of the land use and development regulations in the County. In particular section 22-2-30 Urban Development and section 22-2-90 commercial development. This project will provide services for with renting out RV storage space and providing a pet crematorium center. This also falls within section 22-1 -120 the comprehensive plan guiding principles. The site is showing signs of decline and lack of upkeep. This proposal will be improving the site's current condition, with removal of multiple framed buildings / storage sheds on site. The form, scale, and design of this proposal will enhance the site from North County RD 13. The land use would reinvest and improve the economic vitality and appearance to the site, the site will be attractive, compatible commercial redevelopment that environmentally sound and designed to be functional and attractive for the intended use. We are also proposing landscape screening for the RV storage buildings from the view of North County RD 13. 3. Explain how this proposal is consistent with the intent of the Weld County Code, Chapter 23 (Zoning) and the zone district in which it is located. The current proposal is in the zone district (A) agricultural, this proposal will be in compliance with Section 23-3-40 Uses by special review. 4. What type of uses surround the site (explain how the proposed use is consistent and compatible with surrounding land uses). Most of the surrounding land use is specifically agricultural, although in the immediate vicinity if the site there are development plans in process for special review with the County. The most applicable is the site directly to the North East (USR-1584), the proposed use for this site is a cement plant and currently has use types of construction bus, shop, and office. 5.

We will also be removing 4 existing wood structures. Landscaping - The proposal will be providing landscaped screening to the public right-of-way County Road 13 to the new RV storage buildings. The existing landscaping and structures on site will provide screening of the parking lot. Fencing - We will be proposing a new fence that will enclose the perimeter of the RV storage area. Drainage - The site is designed to sheet flow with the use of new proposed grading and swales to the proposed onsite detention pond. The development runoff is will drain in a similar manner to the historic pattern. The runoff will flow from the North to the Southern portion of the site where the proposed detention pond is located. The detained runoff will be released to the property to the south of the proposed development, this also is inline with historic drainage of the site. Health Department 1 . It is not clear on who provides water on the property. The water provider is Little Thompson Water District. The appropriate documentation from the water district has been provided with the most recent statement from Little Thompson Water District. 2. How many septic systems will be installed? We will be proposing 1 septic system on site, though the percolation rate was so minimal (120+ min/in), a traditional septic system is not feasible. We will need to evaluate other methods for sewage disposal such as evapotranspiration, mounded sand filter., 3. Will each house have a separate system? Will the crematorium and RV storage have separate systems? No, we have a proposed location on site for the septic system. 4. Will animals be euthanized on site and if so is there a vet on site? If so will there be any waste associated with the procedure and will any other vet related procedures be done? Animals may be euthanized on site by special request only and at the time a vet will be called to the site, there will not be a full time vet on site.

USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL RE PORT HARRIS RV JUNE 30, 2015 GENERAL LOCATION AND DESCRIPTION A. Location : The site is located in the southwest 1/4 of Section 18, Township 5 North, Range 67 West, of the 6th Principal Meridian, County of Weld, State of Colorado. The project is located east of Weld County Road 13, south of Highway 34 and north of Weld County Road 56. Furthermore, the site is located south of the Union Pacific Railroad. The site currently contains an existing residence and several small out buildings. The property has been used for agricultural purposes in the past. The site is bound by undeveloped parcels on the south, west and east. An industrial development is north of the proposed site (north of the railroad tracks). There are no major open channels or facilities adjacent to the site. B. Description of Property: The Harris RV site consists of approximately 8.2 acres, including road right-of-way. The project will consist of five (5) RV storage buildings, two (2) modular units and a pet crematorium. The existing house is to remain. The development will also consist of drives, accesses, parking areas and landscaping. The site is bound on the north by the Union Pacific Railroad; south, west and east by undeveloped property. The site generally slopes from the north to south with slopes ranging from approximately 1 .0% to 2.0%. The site currently drains undetained onto the property to the south of this property. Off-site flow onto the proposed site is minimal. Additionally, current ground cover on the lot consists of vegetation, including weeds, grasses, trees, gravel and buildings. According to the SCS soils map, the native soil in the area is as shown in the table below. Map Unit Map Unit Name Hydrologic Soil Symbol Group 42 Nunn Clay Loam, 1 to 3% slopes C 78 Weld Loam, 0 to 1% slopes C 82 Wiley-Colby Complex, 1 to 3% slopes B Refer to the Appendix for additional information. www.jub.com Page 1 J-U-B ENGINEERS, Inc. USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL REPORT HARRIS RV JUNE 30, 2015 The existing drainage facilities near the site include an existing roadside ditch along the east side of Weld County Road 13. Furthermore, there is a drainage swale along the south side of the existing railroad tracks. There are no existing irrigation facilities on the proposed site. II . DRAINAGE BASINS AND SUB-BASINS A. Major Basin Description: This site is not located within a master planned basin by Weld County. The subject property is shown on Flood Insurance Rate Map (FIRM) Community Panel Number 080266 0615C. The site is located within Zone C (areas of minimal flooding). Refer to the Appendix for additional information. B. Sub-basin Description: The proposed development site historically drains from the north to the south. The site currently releases to the property to the south undetained. There is an existing roadside ditch east of Weld County Road 13 and south of the Union Pacific Railroad. Minimal off-site runoff enters the property. The drainage patterns proposed with the development of this site are generally consistent with the existing drainage patterns. III. DRAINAGE DESIGN CRITERIA A. Development Criteria and Reference Constraints: This proposed development is not within a master planned basin by Weld County. Detention for the proposed site development will be provided onsite. The detained runoff will be released onto the property to the south of the development, in the historic pattern. B. Hydrological Criteria: The design storms for this project are the 10-year and the 100-year recurrence intervals. Runoff is calculated using the rational method since all basins are smaller than 160 acres. The rational method calculations are computed by the following: Q = ciA where: Q = Runoff in cubic feet per second c = Calculated runoff coefficient for design event = Storm intensity in inches/hour A = Basin area in acres www.jub.com Page 2 J-U-B ENGINEERS, Inc. USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL REPORT HARRIS RV JUNE 30, 2015 Hydrological calculations have been prepared in accordance with the Weld County Engineering & Construction Criteria, Chapter S — Drainage Criteria as well as the Urban Drainage and Flood Control District Criteria Manual. Rainfall information was obtained from NOAA Atlas 14, Volume 8, Version 2. Please refer to the Appendix for additional information. The area that drains to the detention pond is roughly 7 .67 acres. Detention for this project was calculated using the Modified FAA Method. Furthermore, the historic 5-year release (3 .96 cfs) was used in this calculation. The required detention volume was calculated to be 0.89 ac-feet, plus an additional 0. 15 ac- feet for water quality capture volume (WQCV). Please refer to the Appendix for additional information. C. Hydraulic Criteria: The proposed onsite conveyances will be sized to adequately convey the runoff from the major ( 100-year) storm. Proposed conveyances will be sized using appropriate methods. Preliminary hydraulic calculations are shown in the Appendix. The detention pond invert was set at 4895.5 and the 100-year volume is reached at 4897.50. One (1) foot of freeboard is provided in the pond; therefore, the top of pond elevation is 4898.50. The outlet structure will provide for a WQ and 100-year release. An emergency overflow spillway will also be provided for the detention pond. D. Regulations: Drainage design is in accordance with the Weld County Engineering & Construction Criteria, Chapter S — Drainage Criteria as well as the Urban Drainage and Flood Control District Criteria Manual. There are no deviations from the criteria in this report. IV. DRAINAGE FACILITY DESIGN A. General Concept: Runoff from the site improvements will be conveyed via overland flow, sheet flow and swales to the proposed onsite detention pond. The developed runoff will drain in a pattern that is generally similar to the historic flow path. The runoff will flow from north to the southern portion of the site. The detained runoff will be released to the property to the south of the proposed development. The detention pond will contain an outlet structure and water quality component. The outlet structure will contain a plate with perforations to slow the release of detained runoff www.jub.com Page 3 J-U-B ENGINEERS, Inc. USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL REPORT HARRIS RV JUNE 30, 2015 Furthermore, the detention pond will contain an emergency overflow spillway on the south side. An evaluation for the existing facilities will be completed as part of the final design process. Basins Basin A Basin A is within the northeastern portion of the site and contains three (3) proposed storage buildings, as well as gravel and concrete areas. This basin generally flows from the north to south to Design Point 1 via roof drainage, sheet flow and swale. This basin flows to the onsite detention pond and is then released through the outfall pipe. Basin B Basin B is within the central portion of the site and contains one (1) storage building, as well as gravel and concrete areas. This basin generally flows from the north to south to Design Point 2. This basin flows into Basin C. Basin C Basin C is within the central portion of the site and contains one ( 1 ) storage building, as well as gravel and concrete areas. This basin flows to Design Point 3 and into the onsite detention pond, prior to release through the outfall pipe. Basin D Basin D contains the majority of the site. This basin includes several buildings, parking and access areas as well as landscaping. This basin generally flows from the north to south. This basin flows to the onsite detention pond and is then released through the outfall pipe. B. Specific Details: The proposed detention pond will need to be maintained and inspected at regular intervals to confirm the pond is functioning as designed. The pond can be accessed from the north side, near the turn-around for the storage units. The facilities should be accessible for maintenance or necessary repair. V . STORMWATER QUALITY AND SEDIMENT/EROSION CONTROL A . Stormwater Quality: The proposed drainage design utilizes water quality capture volume (WQCV) within the detention pond as a permanent BM P. The WQCV was calculated using UDFCD spreadsheets, with a 40-hour drain time. Please refer to the Appendix for additional information. www.jub.com Page 4 J-U-B ENGINEERS, Inc. USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL REPORT HARRIS RV JUNE 30, 2015 B. Sediment/Erosion Control: The grading of the site will occur during the initial phase of construction. Several sediment and erosion control measures will be incorporated into this initial phase of construction. The initial sediment and erosion control measures to be installed shall include silt fence around a portion of the southern end of the site, as well as vehicle tracking control at the construction entrance (western site access). Furthermore, additional measures for sediment and erosion control shall consist of providing wattle filters within the proposed swales and detention pond. Also, there will be an area designated for a concrete washout. All proposed drainage improvements shall be thoroughly cleaned and inspected at the completion of site construction. Additionally, any area that has been disturbed by construction activities and left exposed for more than thirty (30) days, shall receive drilled seeding and straw mulch at 2 tons/acre, until permanent landscaping or ground cover has been provided. All stormwater quality and sediment/erosion control measures shall be regularly inspected and maintained during and after the completion of construction for the site. Furthermore, sufficient care shall be taken by the contractor with materials handling and storage. The proposed measures for sediment and erosion control shall he updated as necessary during construction, and as warranted by site conditions. VI. CONCLUSIONS A. Compliance with Weld County Code: The drainage design for the Harris RV site is in general compliance with the Weld County Engineering & Construction Criteria, Chapter S — Drainage Criteria as well as the Urban Drainage and Flood Control District Criteria Manual. Furthermore, existing drainage improvements are utilized in so far as practical and disturbance is minimized. B. Drainage Concept: The proposed storm drainage improvements for the site should provide adequate protection to the site and improvements downstream. Also, the drainage design for the site should not negatively impact the existing storm drainage adjacent to the site. There are no irrigation company facilities on the proposed site. www.jub.com Page 5 J-U-B ENGINEERS, Inc. USE BY SPECIAL REVIEW DRAINAGE AND EROSION CONTROL RE PORT HARRIS RV JUNE 30, 2015 VII.

Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission . Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential , soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material . These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.

Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values. Please refer to NOAA Atlas 14 document for more information.
