College Avenue P.O. Box 580 Fort Collins, CO 80522-0580 RE: WATER S17IRVICE TO BURNS RANCH AT QUAIL RIDGE RBD JOB NO. 394-001 Dear Ms. Whetstone: The City Water Utility Department has indicated that it is currently unable to provide adequate water service within the Burns Ranch to any house built above elevation 5200. This means that the highest water fixture should not be located above 5200 according to the City Water Utility Department. According to Warren Jones' memorandum dated 07/26/90, he would allow residential sprinkler systems to reduce the fire flow requirements to 500 GPM. In addition he would accept a lower fire flow (less than 500 GPM) if the developer would be willing to make modifications to the possibility of fire spread from house to house. �� are therefore proposing, at this Preliminary Plat approval time, to use a Booster Pump System in order to provide adequate residential flows and pressures as well as a 500 gpm fire flow at adequate pressure. The proposed Booster Pump System can be located near lot 1 within the Burns Ranch. A booster pump station consisting of: a constant speed pump, an identical backup pump, and an air charged bladder type pressure tank would work well for the Other Offices: Vail.

College Ave. Fort Collins, CO 80524 RE: Burns Ranch at Quail Variance Request RBD Job No. 394-003 Dear Mike: MAY g May 6, 1991 Ridge Phase One We understand that it is the policy of the City of Fort Collins to require that all streets be designed to meet City Standards as published irk the Design Criteria and Standards for Streets, City of Fort Collins, July, 1986. For the Burns Ranch development, three of the City standards are not being met and a variance to the City standards is hereby being requested. The three situations are as follows: 1. The grade of any street intersecting an arterial street should not exceed a slope of 2% for a distance of 125 feet from the right-of-way of the arterial street. We are requesting a variance to allow a distance of 2 car lengths (40 feet) from the future flowline P.I. of Skimmerhorn Street and Overland Drive to the point at which the 2% slope changes. The 2% slope is not being varied. The standard is included in the City Standards on page 8, section 1.02.03.05. In order to gain enough elevation on Skimmerhorn Street to clear the existing'farmers irrigation lateral at the top'of the hill,' the above variance is being requested. If we are unable to clear the existing irrigation lateral, then the irrigation lateral will need to be siphoned under Skimmerhorn Street. Other offices Denver MT778 7338 • Vail 303'476 6340 • Colorado Springs 719-598-4107 • Longmont 303%678-9584 By varying the design standards, limited vehicle stopping space will be provided at the stop sign on Overland Trail. Due to the limited size of the Burns Ranch development, this is not anticipated to be a problem. The public health, safety, and welfare of the residents of Burns Ranch at Quail Ridge and their guests is not expected to be affected by reducing the available stopping spaces at the stop sign at Overland Trail. 2. The maximum center line grade on any residential street should not exceed 8%. We are requesting a variance to allow a maximum center line grade of 10%. The standard is included in the City Standards on page T- 2, Table 2, Section. 1.02.03. In order to gain enough elevation on Skimmerhorn Street to clear the existing farmers irrigation lateral at the top of the hill, the above variance is being requested. If we are unable to clear the existing irrigation lateral, then the irrigation lateral will need to be siphoned under Skimmerhorn Street. By varying the design standards, additional sanding of Skimmerhorn Street by the City of Fort Collins during the winter months, will be required to enable vehicles to safely travel down Skimmerhorn Street to Overland Trail. Due to the limited size of the Burns Ranch development, this is not anticipated to be a problem for vehicle access. The public health, safety, and welfare of the residents of Burns Ranch at Quail Ridge and their guests is not expected to be affected by increasing the maximum center line grade on Skimmerhorn Street to 10%, as long as the City of Fort Collins maintains the street with adequate sand during the winter months. 3. The design speed on any residential street should be 30 miles per hour. We are requesting a variance to allow a reduction to 15 miles per hour on Skimmerhorn Street, immediately uphill from the irrigation lateral, in order to create a comfortable speed on 3 short vertical curves. The standard is included in the City Standards on page T- 2, Table 2, section 1.02.03. In order to create a low point in Skimmerhorn Street immediately up hill from the irrigation lateral for drainage purposes, and given the location of the irrigation lateral and Alumbaugh Court, a triple vertical curve dip has been created per Figure II of the City Standards. Due to the volume of storm water runoff and E the desire not to create cross basin diversion per the Stormwater Utility Department guidelines, the dip/low point has been created. Bel varying the design standards, a reduction in the speed limit to 15 miles per hour is required to safely enable vehicles to travel along Skimmerhorn Street through the drip area. Due to the limited size of the Burns Ranch development, this is not anticipated to be a problem for vehicle access. By creating a dip in Skimmerhorn Street, the reduced speed limit should provide a means for vehicles to slow down before traveling down the 10% slope to Overland Trail. The public health, safety, and welfare of the residents of Burns Ranch at Quail Ridge and their guests is not expected to be affected by reducing the speed limit at the entrance portion of Skimmerhorn Street to 15 miles per hour. Appropriate signing has been provided on the Utility Drawings for the dip and reduction in speed limit. Thank you for consideration of these three variance requests.

The Burns Ranch development is planned as a foothills residential development within the City of Fort Collins Foothills Zoning District (RF Zone). Skimmerhorn Street between Overland Trail and Alumbaugh Ct. traverses through 250 foot and 200 foot vertical curves, cuts of up to 12.5 feet and will contain only one residential lot on the southeast side. The need for a storm sewer system does not become necessary until a point immediately west of Overland Trail. A special 45 foot CDOH type R curb inlet is proposed on the north side of Skimmerhorn Street immediately west of Overland Trail.

The City utility Services Stormwater department has approved the drainage concepts of allowing storm water runoff to traverse down Skimmerhorn Street and be collected immediately west of Overland Trail. The approved report titled "Final Drainage and Erosion Control Study for Burns Ranch at Quail Ridge First Filing" states that Skimmerhorn Street between Overland Trail and Alumbaugh Ct. will contain sidewalk only on the southeast side.

Indicated in red on the sheets are the verified elevations of the storm drainage facilities for the first filing. As of this date, each drainage item proposed on the Utility Plans, accept the riprap at the end of the 24" pipe, have been installed. For erosion control measures, the temporary swale along Overland Trail was intended to receive a grass seed and mulch after construction, but specific directions as to this design intent were not included on the Utility Plans. The specific direction as to the grass seed and mulch design intent was given to the Contractor during preparation of their final bid for the first filing improvements. As of this date the seed and mulch items have not been installed within the temporary swale along Overland Trail. In summary, the drainage improvements for Burns Ranch at Quail Ridge First Filing should perform in compliance with the intent of the drainage report. The temporary swale along Overland Trail has sufficient capacity to transport storm water runoff from the Burns Ranch First Filing to the existing Quail Hollow Sixth Filing drainage facilities, as the swale was constructed deeper than originally intended. Thank you for your time and consideration of this Certification submittal. Sincerely, RBD, INC. Kevin W.

The pump will be sized to meet the maximum hourly residential demand within the Burns Ranch and the pressure tan}; will be sized to minimize the frequency of p•_r.p ;tarts. This type of booster pump station is readily available _.. a compact factory built package manufactured by Engineered Fluid Process and distributed by Falcon Supply, Inc. In addition to the above described system, we propose to include a fire pump in the factory built package. The system would be connected to a standby power generator which would be automatically activated by power outages. The booster pumping station would be located below ground and the standby power generator above ground. The subject of maintenance is always an issue when the use of pumps comes into play. Where pumps are used, whether it is in a water or sewage treatment plant, or in a booster pumping station, maintenance will be needed. The proposed booster pumping station at the Burns Ranch can easily be connected by telemetry to an alarm system at the City of Fort Collins Water Treatment Plant or City Service Center. Thus in the event of a maintenance problem, the City of Fort Collins Water personnel would be immediately notified. RBD Inc. has designed numerous booster pumping stations for various clients and each system is currently functioning very well. The Vail Valley Consolidated Water District, managed by Jerry Bender, currently has five packaged booster pumping stations in use which were manufactured by Engineered Fluid Process. Jerry can be contacted at 476-7480 in Vail if you desire to review reliability or maintenance issues with him. Please find enclosed a copy out of the Engineering Fluid Process catalog of a typical below ground package water booster pumping station. This will help you visualize what the system would generally look like. We believe that the above described water booster pumping system would work very well at the Burns ranch. This project's location is unfortunately at a difficult elevation where the City of Fort Collins water system is at its limit of service. Construction of a water storage tank to create a third pressure zone would be very costly due to the fact that such a tank would need to be located at an elevation in excess of 5355. Locating a water storage tank at elevation 5355 would create access problems and in addition the tank would need to be located a significant distance from the Burns Ranch. Thus significant offsite water main costs would occur in delivering water from the tank to the Burns Ranch. For these 2 reasons we are proposing to use the above described on site Water booster pumping station. Thank you for consideration of this matter.

Rex discussed the street side slopes behind Skimmerhorn St. through the sandstone and claystone soil. Mike said that the slope behind the walk could increase to 2:1 as long as the soil is stable from the angle of repose and can be proven from the soils report. Next we discussed the street design on Skimmerhorn St. Kevin reviewed the original street design criteria as given to him by Mike and Kerrie. Mike mentioned that Matt's calculations did not consider friction factors during a wet pavement, but according to Matt, it appears that his calculations did cover these friction factors. We discussed the street design criteria and referred to page 726 in the 1984 edition of AASHTO. We were unable to locate the comfort factor for sag vertical curves. We discussed the length of flat street immediately west of Overland Trail on Skimmerhorn St. A distance of 96' plus 25' for a car length was discussed for a number from the future flowline P.I. to a point in the vertical curve. We discussed having 40% of the stopping distance in the vertical curve. We discussed using 3% as the initial grade coming off of Overland Trail and Mike said 3% was OK to use. Mike said he does not want a long length of steep street as currently designed, but instead he wants a short length of steep street. Mike wants a final variance on what we come up with on the final street design on Skimmerhorn St. and wants Matt to back it up with his calculations on stopping distances etc. We discussed sidewalks. It was decided that a sidewalk is required on one side of Skimmerhorn St. Rex prefers the southeast side due to the 2:1 cut slope. Rex also discussed using a 4:1 slope on the northwest side where there is no sidewalk, but Rex would need to review this with his neighbor Mr. Herring. Mike mentioned that offsite deeds will need to be into the City before the June P&Z hearing. Rex will need a separate dedication for land between Burns Property and the ROW of Skimmerhorn St. on the Herrings property. Next we discussed the tracts. It was decided that Tract F will be deeded to the Fort Collins -Loveland Water District. Tracts A, B, and E will be deeded to the City. Tracts C & D should be platted as conservation easements. These tracts will be conveyed after the plat has been filed, and under separate deeds. Mike wanted language on the plat in reference to these tracts, others disagreed. Rex will get his attorney working on the deeds for tracts A, B, E, F. We discussed calling the tracts, Open Space,Access, Drainage and Utility Easements on all tracts except Tract F which goes to the Water District. It was noted that the Plat is actually a replat not a new plat. Tracts C & D should be excluded from public access. Drainage issues were discussed and Rex mentioned he'd like to take some of the 100 year storm water down Skimmerhorn St., through Quail Hollow Filings 3 and 4 and onto the Filing 5 pond. It was decided by the group, that the project would remain on the June P & Z hearing. Therefore, the plat must be immediately revised and resubmitted to Kirsten. The plat is due on Wednesday June 19th according to Rex. Kevin will confirm the date and time. Engineering Consultants 209 S.
