Lift Station Applications HCE Project No. 2000075.02 Dear Mark, We received a copy of the staff report for the lift stations yesterday evening and issue this letter to clear up the issues stated in the report. Calculations The staff report is confusing the capacity of the lift station and the actual amount of sewage that will be sent to the treatment plant. The peak hydraulic number stated on the application (169,050 gal/day for L.S. #1) is based on the Roaring Fork water and Sanitation District's calculations that were used for development of their treatment plant. It is the expected peak day flow of sewage to the plant by the Rose Ranch Development. The lift stations cannot be designed on this calculation as hourly flows can be much higher. The calculation stated in the staff report of 241 ,500 gpd translates to a flow of 168 gpm. The design for lift station one is 320 gpm which would be a flow of 460,800 gpd, but this flow would not occur with the 322 units at Rose Ranch. Therefore there has to be a distinction between the peak daily flow and peak hour or minute flow for the lift stations. Adjacent Properties As you can see from above there is additional capacity in the design of the lift station. The application is stating what is being applied for at this time since no other properties have approached Rose Ranch or the Roaring Fork Water and Sanitation District to make agreement for sewer service. In the event that these properties do decide to tie into the Rose Ranch system the District will determine the connection point based on their facilities and capacities. If the connection point is determined at the Rose Ranch lift stations their capacity will be re-evaluated and the pumps can be replaced if necessary with pumps of adequate capacity. This is the same process that Rose Ranch had to go through to get the district to provide sewer service. We feel it is not unreasonable for the adjacent developer to provide the cost for the upgrade when and if it happens.

Staff and the Board of County Commissioners approved this development for preliminary and final plat. The design of the subdivision has always had these two lift stations, this issue was not raised in the review of the project or in the approval of the project. We ask that the Board recorrmend approval of the application for the reasons stated above. Sincerely, HIGH COI.INTRY ENGINEERING, INC. Eric P. Tuin, E.I. Project Engineer /*.q* be Hope, P.E.

RECEIVED nPn 2 i, 2rlr;2 April 22,2002 Dear Planning and Zoning Commission, At the Wednesday night April l0th P andZmeeting on public comments for Peach Valley Vistas, we had overlooked to mention other items of concern. We hope these thoughts, ideas and suggestions will be taken into concideration in the planning of this new subdivision. Please in respect to nature help preserve the value of the farm and country atmosphere and character. This site and portion of land is the west entrance of Peach Valley. It is also the west end of the valley just before rising upon the Mesa. We'd like to see it be welcoming and pleasant both during the day and at night. Signs advertising this subdivision need to be created in character to the farm valley. The layout of the land needs to incorporate land use for bike paths, walks and playareas. The roads of 6 and Z4,Davis Point Road (236), and the Peach Valley Road (214) are all dangerous roads for children at play, We'd like to see the absence of street lights. The neighboring subdivision (Peach Valley Acres) has no street lights making the night very pleasant. The covenant of Peach Valley Acres has a good deal of respect for both neighbors living in the subdivision as well as those neighbors outside of it. Keeping this intact with the Vistas project would be greatly appreciated. Recent changes throughout Peach Valley in some of the new single family dwellings as well as old dwellings with new occupants is the lighting on the outside of the homes and even some on the inside of the homes. These lights are very bright and give an obvious glow over the valley. The night sky is a value to what makes country country. There is a need to distinguish day from night. There is a need to not send every night creature that ventures these areas to the working farms, ranches and orchard areas nearby. In our farm business we watch the night sky as well as the day sky for change and dicision making. We have a great concern about the quantity of water needed for the proposed amounts of homes. Throughout the area several wells have dropped or gone dry. We are in a drought year. How long it will continue, who knows. We've been known to have droughts last a year to two or three years. Caution and concern for adequate water for all is needed. The more homes the less water availability for everyone in the valley. The placement of the homes upon the land needs to be taken seriously. Nature controlls man. It has happened in this valley before after a drought season. The great gulley washer of a flood. The time for such a flood is approaching. The last big one was 14 years ago. We had lake front property. Here again less homes offer a safer balance. We'd like to see some assurance that road wear and road safety will be a priority during all construction phases. The heavy construction vehicle traffic creates much road damage as well as traffic hazards. Davis Point is a real concern for safety. Thank you for your time and we hope good sound solutions to the water, house and lighting, land use and layout, safety and compatabllity to the environment will be met. \..*$,"^--e*ftkry
