Home My WebLink About1.10 Water supply plan) Section 4:91 Water Supply Plan Water service for this development will be provided by the Consolidated Metropolitan District. (See the "Intent to Serve" letter attached .) Detailed water supply calculations are contained within the attached Water Supply Report. Mr. Bruce Smith, District Manager of the Consolidated Metropolitan District indicates that "the peak daily water and sewer service requirements are comfortably within the capabilities of the District's existing facilities ." A copy of the Judgment and Decree, Case No. 82CW107 for the Battlement Mesa Metropolitan District is included as Exhibit B for reference. The majority of this property, Parcel 5-1 and a portion of Parcel 5-2, is located within Battlement Mesa Pressure Zone B, and will be served by existing twelve-inch and eighteen-inch potable water mains located on the south side of South Battlement Parkway adjacent to this property. The upper portion of Parcel 5-2 is located in Battlement Mesa Pressure Zone C. The infrastructure facilities necessary to serve this area have not yet been constructed . The Water Supply Plan proposes two alternatives for providing water service to this area . Those options will be further detailed as part of a future preliminary plan submission for Tracts 4 and 5 at a later date. As each residential area is developed, eight-inch water lines will be-extended from the perimeter mains and looped through the development. Fire hydrants will be placed throughout the project as necessary to provide both fire protection and the ability the flush the water lines at appropriate locations. More specific utility plans will be developed as a part of subsequent applications as the residential areas are subdivided at a future time.

SGM 118 West 6th, Suite 200 Glenwood Springs, Co 81601 Dear Mr. Gordon: June 21,2005 Re: Water & sewer service Parcels 5-1 & 2, Battlement Mesa p. 1 Thank you for memorandum of June 7 discussing the preliminary plans for Parcels 5-1 and 5·2 (commonly referred to as Jack's Pocket I & 2 and portions of3 & 4) at Battlement Mesa. It was faxed to this office on June 17. Based on the information provided, it appears to me that the peak daily water and sewer service requirements are comfortably within the service capabilities of the District's existing facilities. Both parcels are within the Battlement Mesa PUD. Parcel 5-1 is within the jurisdictional limits of the Consolidated Metropolitan District and therefore is currently eligible to receive services from the District. Parcel 5-2 is partially within the District, and the remaining portion is eligible for inclusion under the existing Board policies and Rules and Regulations of the District. Today I have received a Petition For Inclusion of the referenced property into CMD. The Board of Directors is supportive of the Petition and ordered that Publication be made for a July 28 Public Hearing on the Petition. I anticipate the inclusion will be completed at that time. Once Board of Directors approves the inclusion, I can unequivocally state that CMD has the capability and will provide service to Parcel 5-2, as well. In summary, the Consolidated Metropolitan District has the capacity to provide water and sewer service for the proposed development as outlined in your letter. Service is immediately eligible for Parcel 5-1. Service for Parcel 5-2 will be available upon inclusion into the CMD. Service for eitherlboth properties is subject to compliance with the Rules and Regulations of the District. Please contact me if you need additional information. 2z;;~ R.

Hopefully, the information you requested is contained below and it will allow you to comfortably send us the letter. I am going to use a heading format in an attempt to keep the length of the information to a minimum. Overall Scope A Preliminary Plan for PUD areas 5-1 and 5-2 shown on the original Master Plan for Battlement Mesa. Referring to both your water system and sewer system maps_of April 1983, it is also shown as Parcels 5-1 and 5-2, on which currently your Zone A storage tank and Zone B pump station are located. It is my understanding that this property is also known as Jack's Pocket Village. Specific Scope The intent is to have a Preliminary Plat done for that portion of the two parcels that remain after previous platting as follows: • Fire station parcel. • Church parcel. • Battlement Cemetery parcel. • Zone A storage tank parcel. • Zone B water booster station parcel. At this time, the area is being platted as five individual parcels so that the property can be developed in phases. A six acre parcel Business Center parcel is being designated at the intersection of South Battlement Parkway and Stone Quarry Road. In addition, one parcel is designated as an access and utility parcel. The remaining three parcels, which make up the balance of Original Parcels 5-1 and 5-2 are residential. These three parcels will be the subject of subsequent preliminary plans at a future date. At that time, more specific plans, showing the lot layouts and engineering design for the utility systems will be presented. ··6· •................... JOhe17,2005 Mr. Bruce Smith Page 2 At this time, we would like to establish the District's ability to serve the overall property based on a conservative estimate of the number of residential units proposed. When development of the individual lots is proposed in the future, we will review those specific plans with the District in terms of the actual number of residential lots and their configuration. Practical Description The balance of Parcels 5-1 and 5-2 of the Battlement Mesa PUD. The balance of the parcel is the original parcel, less the developed or previously deeded parcels as noted above. The property is bounded by South Battlement Parkway, County Road 308, County Road 302 and Stone Quarry Road, beginning on the north side and proceeding clockwise. Legal Description The legal description is very long and involved, but is included on the copy of the Preliminary plat given to you last week when you met Debbie Duley in Tom Beard's office .. Service Requirements Under the original zoning, Parcel 5-1 was zoned as Medium Density Residential, with a maximum density of 12 units per acre. Parcel 5-2 was zoned Low Density Residential, with a . maximum density of 5 units per acre. A sitefor an elementary school was included within Parcel 5-2, and a service station site was included with Parcel 5-1. Under the current proposal, the elementary school will not be built. That property will revert to residential zoning. Also please note that the original service station parcel at the intersection of Stone Quarry Road and South Battlement Parkway is being proposed as a 6.0-acre parcel as opposed to the approximate 1.4 acres on the original Battlement Mesa Master Plan. Of this area, 2.2 acres will be developed as a service station and car wash. The remainder of the six acres will be developed as neighborhood commercial. The remaining residential area, 61.56 acres, will be developed at an approximate density of five units per acre for a maximum density of 310 residential units, rather than the higher density anticipated under the original Battlement Mesa Master Plan. There will also be a decrease in service requirement by elimination of the school. Service requirements are therefore as follows: • 310 dwelling units. • A six-acre commercial parcel, divided up into a 2.2-acre Kum & Go service station and a 3.8-acre light commercial area. JUne 17,2005 Mr. Bruce Smith Page 3 In summary, the Preliminary Platting process will result in a development plan with a lower service requirement than what was originally proposed by the original Battlement Mesa Master Plan. ______________________________ DWG _________________________ __ lec/2004-238.001-20 cc: Tom Beard, tbeard@battlement.net Debbie Duley, SGM WATER SUPPLY PLAN This report has been prepared to conform to the April 2005 "Design and Construction Standards and Specifications, Appendix C" for the Battlement Mesa Metropolitan District. Specifically, the scope of this section will be to summarize the proposed development from a water supply standpoint, review the existing available water system components to serve this development and to review proposed system designs. Proposed Development From a water system standpoint, the following table summarizes the proposed development: DEVELOPMENT SUMMARY Size Density Total Parcel Designation (acres) Use Use Residential 5.1 Tract 2 -Residential 25.7 5.0 d.u./acre 130 d.u. Tract 1 -Service Station 2.2 NA 2.2 acres Tract 1 -LiQht Commercial 3.8 NA 3.8 acres Fire Station -ExistinQ ------Existing Residential 5.2 Tracts4/5 Residential 35.7 acres 5.0 d.u./acres 180 d.u. Elementary School ---------Church -ExistinQ ------ExistinQ Totals 310 d.u. Service 2.2 acres Station Light 3.8 acres Commercial NOTE: d.u. = dwelling unit The proposed development is generally consistent with the Baltlement Mesa Master Plan for the development area. From a water service standpoint, the main changes are the elimination of an elementary school parcel of 7.2 acres, and an increase in the size of the non-residential area indicated as "service station" on the original master plan. 1 Existing System Referencing the master water system map entitled, "Water System" dated April 1983, the development parcels are primarily in Zone B of the water system, with the far easterly portion in Zone C. Referencing the Cemetery Parcel Master Utility Plan, water systems in place to service this development are as follows: • An 18"/12" diameter water main in South Battlement Parkway along the northern perimeter of the development. • An 18"/12" diameter water main in County Road 302, along the southern boundary of the property. • An 18" waterline that runs through the property from north to south, beginning at the Zone B pump station and terminating on South Battlement Parkway under the existing access road to the property. • The Zone B pump station is located within the boundaries of the development. It is indicated as a 12.5 MGD pump station. • The majority of the project will be served from the Zone B storage tank. This tank is located off site. The existing Zone B storage tank is a 3 MG tank. Within Zone B, the water system master plan indicates anticipated peak day working pressures from 40 psi at the 5615 contour to approximately 127 psi at the 5425 contour. As further discussed below, facilities within Zone C do not exist at the current time. Zone C service alternatives are discussed below. Water System Demand The following table summarizes the service demands for the development: EQUIVALENT UNIT SUMMARY Service Unit Total Parcel Designation Reqrmnt EQR's EQR's Residential 5.1 Tract 2 -Residential 130 d.u. 1 EQR/d.u. 130 Service Station 2.2 acre 59 d.u./acre 129 Light Commercial 3.8 acre 16 d.u./acre 59 Residential 5.2 Tracts 4/5 Residential 180 d.u. 1 EQR/d.u. 180 Total EQR's 498 NOTE: • d.u. -dwelling unit • EOR = 3.2 population equivalent • Assume for service station wI car wash, 187.5 p.e.lacre or 59 d.u.lacre • Assume for liqht commercial, 50 p.e.lacre or16 d.u.lacre 2 Based on the equivalent unit count, the service requirements are as follows: • Equivalent units -498 EQR's • Equivalent unit service rate -3.2 persons/EQR @100 gpd/p for combined in-house and irrigation usage, or 320 gpd/EQR • Average day demand -498 EQR's x 320 gpd/EQR = 159,360 gpd • Maximum day demand -2.5 x avg. day demand = 398,400 gpd • Peak hour demand -4.0 x avg. day demand = 637,440 gpd It is anticipated that the fire flow requirements for the single-family areas will be 1500 gpm. The fire flow demand for the service station/light commercial area will depend on final building types and sizes. It is anticipated that the fire flow demand will not exceed 2500 gpm. Both of these fire flows are less than fire flows currently required for the adjacent Town Center and Activity Center and therefore are already provided for by the existing infrastructure. Proposed Water System Improvements This land use submittal results in the interior platting of only the service station/light commercial property located in the northwest corner of the property. The remaining residential properties, Tracts 2, 4 and 5, will be subdivided at a future time into single-family and multi-family lots. A specific infrastructure design for those residential subdivisions will be part of a future submission. The service stationllight commercial property will be serviced by extension of service lines and fire hydrants as shown on the Master Utility Plan. The remaining portions ofthe residential properties located with Zone B will be serviced by main line extensions throughout the residential areas. The waterlines will generally follow the roadway corridors. Except for short cul-de-sacs, the system will be looped throughout the development. It is anticipated that the infrastructure within the residential areas will be 8" diameter mains connecting to the perimeter systems. At the time the residential parcels are platted, a computer model will be run of each of the areas to verify line sizes. The infrastructure in Zone C currently does not exist. It is not economical to build the capital infrastructure for Zone C as part of a development of this size. There is the potential only about 50-60 residential units to be located within Zone C in the eastern portion of Tract 5. In addition to water transmission mains, it would be necessary to construct a Zone C pump station and a Zone C water storage tank to initialize a Zone C water system. Options for servicing this portion of the development are as follows: • Construction of a water booster station from the Zone B distribution system to enhance the pressures within the service area. Note that this was the identical approach used for parts of the Mesa Ridge Subdivision directly to the north of the project, a portion of which was located within Zone C. • Extension of the infrastructure from Zone B into this service area. It is estimated that the peak day working pressures at the highest fire hydrant will be between 20-25 pSi, and the pressure at the highest residence approximately 5 psi. Each of the individual residential units would require an individual in-line booster pump in order to maintain higher 3 pressures within the unit. The internal distribution system would be sized to provide fire flows to the individual fire hydrants. The infrastructure servicing the portion of the property located within a future Zone C will be designed to be compatible with the anticipated future Zone C water transmission main size and locations. The Water System Master Plan currently calls for 12" diameter waterlines along the adjacent County Road 308 on the east and County Road 302 to the south. From a fire protection standpoint, Zone B already includes the Town Center and Recreation Center. Therefore, there is already a fire demand in excess of what is required for this development and fire storage is therefore already part of the system. From a water system standpoint, Tract 2 and Tracts 4/5 act somewhat independently in that they are on either side of the 18" waterline which separates them in a north-south direction. The modeling will be done for the entirety of Tract 2 and any portion of Tract 2 that is developed. Likewise, when any portion of Tracts 4/5 is developed, water modeling will be done for those two parcels. Therefore, the final infrastructure deSign for each of those areas will be done at such time as the subdivision layout has been determined. • 4
