HomeMy WebLinkAbout1.11 Wastewater disposal planSection 4:92 Wastewater Disposal Plan SEWER -Sewer service for this development will be provided by the Consolidated Metropolitan District. (See "Intent to Serve" letter attached). A
twelve-inch sewer main extends from east to west along the north side of South Battlement Parkway with eight-inch stubs crossing the Parkway into this property. Near the northwest corner
of this property, the sewer line crosses Battlement Parkway to a manhole located southwest of the intersection of Battlement Parkway and Stone Quarry Road, and then continues along the
south side of Battlement Parkway on its way to the treatment plant. Tract 1 will be served by a new service extension off of the existing twelveinch line. New eight-inch lines will be
extended into each of the residential areas, Tracts 2, 4 and 5, as they are developed in order to provide gravity sewer service to the entire project. All of the new sewer lines will
be designed and built to meet the specifications of the Consolidated Metropolitan District. Upon completion of construction and acceptance by the District, they will be dedicated to
the Consolidated Metropolitan District for maintenance. The attached Wastewater Disposal Plan includes information regarding the wastewater capacity required for the proposed levelof
development onthis property. More specific utility plans will be provided as part of a future preliminary plan submission for each of the residential areas in the future.

285-9631 Dean Gordon, P.E. 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 1 & 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-I 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 r 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-I. 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. District

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 systemand 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.

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 l1nits p-eracre.Asitefor an elemeotary school'iVas inciudeQwithin 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.

WASTEWATER DISPOSAL PLAN This report has been prepared to conform to the April 2005 "Design and Construction Standards and Specifications, Appendix C" for the BaUlement Mesa Metropolitan
District. Specifically, the scope of this section will be to summarize the proposed development from a wastewater disposal standpoint, review the existing available wastewater system
components to serve this development and to review proposed system designs. Proposed Development From a wastewater 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

-Existing ------ExistinQ Totals 310 d.u. Service 2.2 acres Station Light 3.8 acres Commercial NOTE: d.u. = dwellinQ unit The proposed development is generally consistent with the BaUlement
Mesa Master Plan for the development area. From a wastewater 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 nonresidential area indicated as "service station" on the original master plan. 1:\2004\2004-238\Correspondance\Waslewaler Disposal Plan.doc 1
Existing System Referencing the master sewer system map entitled, "Sewer System" dated April 1983, this development comprises the remainder of Parcels 5-1 and 5-2. Referencing the Master
Utility Plan submitted as part of this application, wastewater systems in place to service this development are as follows: • A 10" diameter sewer main in South Battlement Parkway along
the northem perimeter of the development. • Off-site sewer mains from 10" to 24" diameter leading to the wastewater treatment facility. Wastewater System Demand The following table summarizes
the service demands for the development: EQUIVALENT UNIT SUMMARY Service Unit Total Parcel DeSignation Requirement EQR's EQR's Residential 5.1 Tract 2 -Residential 130 d.u. 1 EQR/d.u.

equivalent unit count, the service requirements are as follows: • Equivalent units -498 EQR's • Equivalent unit service rate -3.2 persons/EQR @80 gpd/p, or 256 gpd/EQR • Average day
-498 EQR's x 256 gpd/EQR = 127,488 gpd • Peak demand -4.0 x avg. day = 509,952 gpd Proposed Wastewater 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. J:120Q412004-238\Correspondance\Wastewater
Disposal Plan.doc 2
The service station/light commercial property will be serviced by extension of service lines as shown on the Master Utility Plan. The remaining portions of the residential properties
will be serviced by main line extensions throughout the residential areas. The sewerlines will generally follow the roadway corridors. It is anticipated that the infrastructure within
the residential areas will be 8" diameter mains connecting to South Battlement Parkway. At the time the residential parcels are platted, a computer model will be run of each of the areas
to verify line sizes. From a sewer system standpoint, there are three (3) existing 8" diameter main extension stubs into the overall development parcel. These extensions will be used
unless they prove to be located such that connection is impractical, in which case they would be abandoned. Abandonment of existing extensions may require new extensions from the South
Battlement Parkway sewer. Depending on the phasing of residential development, modeling will be done for composite contributory areas for each phase. The density of residential development
will likely not require more than an 8" collection system. _ 1:\2004\2004-238\Correspondance\Wastewater Disposal Plan.doc 3
