Introduction/Summary This report presents information concerning trunk utility improvements necessary to serve the area immediately north of Highway 5 and west of Galpin Boulevard. This area was previously identified as the "1995 Study Area" and is known as subdistricts BC-7 and BC-8 in the comprehensive sewer plan. The project area is shown on Figure I. The improvements will serve the proposed development by Pulte Homes on the corner of Highways 5 and 41, the Savaryn property, the Westwood Community Church property, and other properties. This project and the proposed developments are proposed to coincide with the planned Highway 5/W. 78th Street frontage road construction. ~t; y 4; Municipal improvements proposed herein include the construction of a trunk sanitary sewer line from just west of Galpin Boulevard to west of Highway 41. The alignment for the sewer was roughly determined as part of the comprehensive sanitary sewer plan and previous projects. The proposed alignment has been modified to facilitate the conceptual plans of the Pulte development. Water main improvements are also planned within the project. The costs of the proposed improvements are detailed in Appendix A. Cost allocation and unit cost summary are presented in the Cost Analysis section. Financing for the project will come from property assessments. A preliminary assessment roll is included as Appendix C. This report is the result of petitions for a public improvement project submitted by Pulte HomeslMills Properties, Paul & Paula Savaryn, and Westwood Community Church. The City Council authorized preparation of a report on March 13, 2000. The final escrow amount agreement from the petitioners was received on May 12, 2000. The proposed improvements contained herein have been discussed conceptually by the City for several years. Sanitary sewer first installed as part of project 91-17 and expanded with BC-7 & BC-8 Area Trunk Utility Improvements Feasibility Report Page 3 subsequent projects has been planned to facilitate this project and serve the project area. Water main planned as part of the proposed Highway 5 Frontage Road project and previously installed as part of Project 97-1 have also been designed to serve the project area. The site is currently planned for a mixture of Residential, High Density, and Commercial uses. This report examines the feasibility of completing utility improvements in the project area. Sewer and water service will be provided by extending utilities in accordance with the City's comprehensive plans. A summary of the proposed improvements with this project includes: I. Extension of sanitary sewer services to the project area. 2. Installation of 12-inch diameter trunk water main. Assessments proposed in this report are consistent with previous feasibility reports for the area, City policy, and the Comprehensive Sewer and Water Plans. The proposed project assessment area is shown on Figure 4. A preliminary Assessment Roll is presented in Appendix C at the back of this report. The proposed assessments are based on the preliminary cost estimates and may be revised at the time of the final assessment hearing based on actual costs, development agreements, and final development plans. The Assessments proposed herein have been coordinated with the assessments for the T.H. 5/ West 78th Street (Frontage Road) Project (City Project 97-6).

Proposed Improvements Sanitary Sewer Sanitary sewer improvements for the project area are in conformance with the City's Comprehensive Sewer Policy Plan and are shown on Figure 2. The project will extend sanitary sewer services from the trunk sewer installed under Improvement Project No. 97-6 (T.H. 5/West 78th Street). Sanitary sewer flow from the project area flows southward adjacent to Bluff Creek and discharges into Lift Station No. 24 on Lyman Boulevard. From Lift Station No. 24 the flow goes through the Lake Ann and Lotus Lake Sewer Districts to the eastern border of Chanhassen and ultimately to the MCES Blue Lake wastewater treatment facility. { f. The proposed sanitary sewer alignment will follow the south side of the wetland adjacent to Bluff Creek. This alignment reduces the depth of excavation required for construction. Final alignment will be adjusted to save existing tree clusters where possible. Geotechnical borings should be completed as part of the design process to determine the extent of piling necessary. The City should consider establishing a trail over the sewer alignment to provide access to the sewer for maintenance. Water Main Water main improvements proposed herein are consistent with the City's Water Supply and Distribution Plan and are shown on Figure 3. A 12-inch diameter trunk main will be constructed on the east side of Trunk Highway 41 from the Longacres Development to the West 78th Street Frontage Road. A l2-inch water main will also be constructed westward across Highway 41 and through the Westwood Community Church property. Water main stubs will be provided to the adjacent developments where necessary. Fire hydrants will be included with the adjacent developments to provide adequate fire coverage. Fire Hydrants will be installed in accordance with requirements from the City Fire Marshall. BC-7 & BC-8 Area Trunk Utility Improvements Feasibility Report Page 6 III. Cost Analysis I Financing Cost Estimate The estimated project cost to complete the street and utility improvements proposed herein are presented below in Table 1. These costs include legal, administrative, engineering, bonding, and interest costs estimated to be 28% of the construction costs. The estimated 28% indirect costs are reviewed at the time of the final assessment hearing. The indirect costs are based on previous similar projects and includes the following: engineering (16%), geotechnical testing (1.3%), bonding (1.3%), legal (0.8%), permits (0.5%), and City administration (8.1%). This estimate does not include easement acquisition costs. Table 1. Project 00-01 Estimated Project Cost Summary (See Appendix A for Detailed Cost Estimate) Item Total Cost BC-7 Trunk Sanitary Sewer $ 674,500 BC-8 Trunk Sanitary Sewer 261,900 BC-7 Trunk Water Main 154,600 BC-8 Trunk Water Main 194,800 Total $1,285,800 Assessments Assessments are proposed to be levied against the benefited properties as shown on Figure 4. A Preliminary assessment Roll is presented in Appendix C. The proposed assessments herein are consistent with City policies and past practice. Assessments under this project have been checked to coincide with assessments proposed under project 97-6, Highway 5/W. 78th Street frontage road, being constructed under separate contract. Page 7 BC-7 & BC-8 Area Trunk Utility Improvements Feasibility Report A summary of the proposed Assessment Rates is presented in Table 2 below. Table 2 Project 00-01 Proposed Assessment Rates Item ß!!!: Sanitary Sewer (Lateral Benefit) $20.00/front foot Water System (12" Lateral Benefit) $24.00/front foot Sanitary Sewer (Trunk Hookup Charge) $1,300 per REU Water Main (Trunk Hookup Charge) $1,694 per REU Assessable equivalent units for sewer and water trunk charges are determined by multiplying the net assessable acreage for each parcel by number of residential equivalent units (REUs) for the planned use. The REUs for various land use types are shown below in Table 3. Net assessable acreage is gross acreage less wetlands and existing highway or county road right-of-way. The assessable equivalent units shown in the preliminary assessment roll are minimum numbers based on existing zoning and land use guideline conditions. Calculations for final assessment purposes will be based on actual development information at the time of the assessment hearing and will be adjusted if actual development intensifies. < Table 3 Residential Equivalent Units (REUs) Land Use Tvne Minimum REUs Per New Assessable Acre 2 3 6 4 2 Single Family Medium Density High Density Commercial/Industrial Public BC-7 & BC-8 Area Trunk Utility Improvements Feasibility Report Page 8 The above REUs are the minimum number recommended to be charged at the time that trunk utility service is provided. If a property develops at a greater number of REUs, additional unit charges will be charged at the time of development based on Metropolitan Council Environmental Services (MCES) Sewer Availability charges (SAC) unit calculations. Small parcels and other properties may be charged a minimum of one unit at this time in accordance with past City practice. Assessment Revenue It is proposed to assess trunk area and lateral charges to the benefited properties. Table 4 below summarizes the estimated revenue from assessments. The table shows a negative revenue. The negative balance of $91,160 will be the City's responsibility and should be funded from sewer and water funds from previous projects which had positive assessment revenue.
