Page 2 VALLEY WEST SEWER TRUNK DESIGN REPORT 1.0 Executive Summary The 360 Ranch Corporation proposes to develop a 404 acre tract west of Ferguson Avenue and south of Durston Road to be called Valley West. At this time, this area is without sewer service, therefore the Valley West Sewer Trunk Line will be built and will serve those areas included in the Valley West Annexation, which includes the Valley West Project, Bozeman Athletic Club West Annexation and that area 300 feet north of Durston Road beginning 1,320 feet west of the proposed alignment for Cottonwood Road eastward along Durston to Flanders Mill Road and that area between Flanders Mill Road, from 400 feet north of the proposed trunk line south to Durston Road, and the connection to the City's existing wastewater system. Total area to be served is 726 acres. (See Service Area Figure 1.1). The proposed trunk line will consist of approximately 16,500 feet of eight inch,ten inch, twelve inch, eighteen inch and twenty-one inch PVC pipe. (See Valley West Trunk Line Figure 1.2). Predicted wastewater generation for the 726 acres to be served by the trunk line is 1,031,160 gpd. The entire area is subject to high groundwater therefore infiltration(I/I)will be included with the wastewater flows predicted. (I/I) into the new line is based on Bozeman's May 1997 Wastewater Facilities Plan suggestion, (150 gpd per acre), for newly constructed sewer mains or 108,900 gpd for this project. Due to the topography of the area,the trunk line will be laid at nearly minimum grade from the connection to Bozeman's sewer system westward to the future intersection of Durston Road and Cottonwood Road. Hydraulic analysis completed during the design of the trunk line indicates that each line will flow the predicted peak flows with used capacity ranging from 13%to 98% of full flow capacity. 2.0 Introduction The proposed Valley West Sewer Trunk will connect to the City's existing wastewater system's Valley Unit Trunk Line at Manhole #946, approximately 3,850 feet northeast of the intersection of Durston Road and Flanders Mill Road, and extend west and south along the future extension of Cottonwood Road to a point approximately 400 feet north of Huffine Lane. The trunk line will follow the alignment of Cottonwood Road, Durston Road and Flanders Mill Road where possible and will be centered in a 30 foot utility easement in those areas where the trunk line crosses private property.

At Manhole #946, the existing trunk line increases in size from an 18-inch line to a 20-inch line. 4.0 Proposed Service Area The service are for the proposed trunk line will consist of the Valley West Annexation, the Bozeman Athletic Club West Annexation, and those properties lying 300 feet north of Durston Road beginning 1,320 feet west of the proposed alignment for Cottonwood Road, eastward along Durston to Flanders Mill Road, and that area between Flanders Mill Road from 400 feet north of the proposed trunk line south to Durston Road, and the connection to the City's existing wastewater system.

The plan indicates that an overall density prediction of 13.3 persons per acre should be used for new development. Valley West Sewer Trunk Line Design Report Page 3 Exceptions to the plan's recommendations are: the Christian Heritage School in which the population is known. Bronken Park in which it is assumed maximum event attendance would be 1500 people. The exclusion of the 10 acre lake being constructed in the western section of Valley West. Infiltration (I/1) allowance of 150 gallons per acre per day will be assumed corresponding to the City of Bozeman's "Wastewater Facility Plan" page 87. This is equivalent to 1.3 persons per acre of wastewater generation.

The plan indicates that an overall wastewater flow of 117 gpd per person should be used for new development. Wastewater generation for Bronken Park is based on 8 gpd/visitor. This information is based on Metcalf and Eddy 3`d Edition, Wastewater Engineering Table 2.5,page 20. Wastewater generation for the Christian Heritage School is 16 gpd/staff and 25 Valley West Sewer Trunk Line Design Report Page 4 gpd/student. This information is based on Metcalf and Eddy, 3" Edition, "Wastewater Engineering", Table 2-11,page 28 (See Table 6.1 for predicted wastewater generation).

The flows predicted for the additional areas require that the trunk line size be increased beyond what is necessary to carry the predicted flows for the Valley West project in some portions of the trunk line. Two approaches are used to illustrate the oversizing of the trunk line. Approach number one compares the overall flow predicted for the Valley West project as a percentage of the total flow predicted. (See Table 9.1). Table 9.1 Valley West Project Percent of Total Flow .Service:Area Area Valley West 292.5 acres 455,160 gpd Subtotal 455,160 gpd Billion Auto Plaza Sub. 19.5 acres 30,344 gpd Norton Ranch Inc. 40.0 acres 62,244 gpd Bozeman Athletic Club West Annexation 135.0 acres 210,074 gpd Christian Heritage School 13.0 acres 2,578 gpd Area North of Durston Road 174.0 acres 270,761 gpd Subtotal 576,001 gpd Total 1,031,160 9pdJJ Valley West contribution to the total flow 44.1%. In approach number two, each line component of the trunk line is sized to carry flow predicted for Valley West. (See Table 9.2).

At full buildout of the described area, it is predicted that up to 98% of the full flow capacity of the trunk line in several areas will be utilized. Construction of the project is expected to begin in the spring of 1998, and be completed by mid-summer of that year. The trunk line will be constructed in accordance with Montana Public Works(MPW) Fourth Edition,January, 1996, Standard Specifications in conjunction with City of Bozeman Modifications to MPW Standard Specifications prepared May, 1997.
