WHEREAS, the City of Rochester and Olmsted County have established an Urban Service Area for the purposes of planning the orderly, efficient and cost-effective development of the undeveloped lands surrounding the City; and, WHEREAS, the Urban Service Area defines the proposed limits of future city growth and thereby establishes definitive areas for which public infrastructure such as roads, water, sewer and storm water must be planned, designed and constructed to serve the ultimate build out of those areas; and, WHEREAS, in 1973, the Public Works Department, with the use of population projections and land use data provided by the Planning Department, completed a "Sanitary Sewer and Water Study" with a primary objective of "the development of a long range plan for the construction of an adequate sewerage system to serve the need of Rochester's metropolitan �rea;" and, WHEREAS, the "Sanitary Sewer and Water Study" consisted of two separate phases of engineering investigation; "one of a systematic evaluation of the existing trunk and sub-trunk sewers to determine its adequacy to convey the expected sewerage flows from an enlarged service area, and another of the development of a long range plan for the orderly and economical provision of service for the suburban fringe area;" and, WHEREAS, the "Sanitary Sewer and Water Study" states that "the establishment of the boundaries and areas of sewer districts is essential to estimating cumulative flows in the various trunk sewers ... for the determination of the adequacy of the in place sub-trunks and trunk line sewers to handle existing and future sewage flows;" and, WHEREAS, the 1973 "Sanitary Sewer and Water Study" recommended that the design and location of a new permanent Lift Station 4 should accommodate sewer flows projected to occur by the Year 2020 from the developing area of Northwest Rochester known as the Northwest Property Owners Association (NWPOA) or otherwise referenced as Sewer Service Area 28A-K (SSA 28A-K), and the portions of the Hadley Valley Sewer Service Area (SSA 29) east of the Zumbro River and north of 37th street N.E., not served with public sewer service. Both of these areas ultimately became part of the Urban Service Area; and, WHEREAS, on November 1, 1976, the City Council received a Preliminary Progress Report from the Public Works Department that set forth Project 7301, Stage 1 of Northwest Area • 1 Trunk Line Sanitary Sewer, Pumping Station, Force Main and Outfall Sewer; and, WHEREAS, at a December 6, 1976, public hearing, the City Council set forth their intent to provide adequate trunk sewer facilities to serve the entire Stage 1 area of approximately 1,000 acres by providing a temporary sewer lift station, outfall sewer and trunk sewers at a cost of $817,510 and further assessing that cost to benefiting property at a rate of $817.51 per developable acre; and, WHEREAS, the City had planned and, in 1977, constructed a temporary Sewer Lift Station 4 (LS 4) to provide sanitary sewer service to approximately 1,000 developable acres in Stage 1 of the developing area of Northwest Rochester known as NWPOA; and, WHEREAS, on May 4, 1992, the City Council set forth Project 7301-91, Extension of N.W. Trunkline Sewer, N.W. Plaza to Douglas Trail, Watermain and Sanitary Sewer to 660 Feet West of 50th Avenue N.W., to serve an area of approximately 1,284 undeveloped acres in Stage 2; and, WHEREAS, at a May 16, 1994, public hearing, the City Council set forth its intent to provide adequate water and sewer facilities, and to have newly developing areas of approximately 775 developable acres in the Stage 2 area pay for the additional infrastructure required to provide adequate water and sewer facilities, including the construction of Stage 2 improvements to the temporary Lift Station 4, all at a cost of$738,121.36, and further assessing the cost of the Stage 2 lift station and trunk sewer improvements against benefiting property at a leate of$392.54 per developable acre and $35.13 per assessable foot; and, WHEREAS, the Stage 1 and 2 temporary Lift Station 4 improvements and the various trunk sewer improvements were designed, financed by benefiting property owners, and constructed by the City to serve the entire SSA 28A-K, consisting of approximately 2,442 developable acres consistent with the "Sanitary Sewer and Water Study" dated August 1, 1973, and City Council approvals on November 1, 1976, December 6, 1976, May 4, 1994, and May 16, 1994; and, WHEREAS, in January, 1996, the City completed, with the assistance of Black and Veatch Consulting Engineers, an update to its Wastewater Collection System Master Plan that provided a cursory review of the capacity of the existing trunk sewers, evaluated the impact on trunk sewer capacity and system adequacy for projected population growth and contributing sewer flows in the community between 1995 and 2020, and made corresponding long term capital funding recommendations; and, WHEREAS, the analysis performed as a part of the 1996 Wastewater Collection System Master Plan expanded the Kings Run Sewer Service Area by 613 acres from its prior western Stage 2 limit of 50th Avenue N.W., to a new western limit of 60th Avenue N.W.; and, WHEREAS, the 1996 Wastewater Collection System Master Plan concluded that certain portions of the trunk sewer system serving areas, previously described as the NWPOA, ore recently named the Kings Run Sewer Service Area and now defined with a western 2 boundary of 60th Avenue N.W., would not have adequate future sewer capacity based on an �ssumed moderate growth rate between 1995 and 2015; and, WHEREAS, the 1996 Wastewater Collection System Master Plan estimated the cost at $3,890,000 to replace certain portions of the existing trunk sewer system to serve the revised Kings Run Sewer Service Area to its new western edge at 60th Avenue N.W., at $3,890,600; and, WHEREAS, the 1996 Wastewater Collection System Master Plan recommended that the new Lift Station 4 should be designed, located and constructed in the future to serve the existing and projected sewer flows between 1995 and 2015 from both the existing Kings Run Sewer Service Area and the portions of the Hadley Valley Sewer Service Area without public sewer service; and, WHEREAS, on June 17, 2002, the City Council received a petition from Western Walls, Inc., and Bigelow Enterprises, Inc, requesting that the city initiate a feasibility study for the "Extension of Sanitary Sewer and Watermain to the Kirkland-Clowes Property in Cascade Township and the Schleusner Property in Kalmar Township"; and, WHEREAS, the City Council referred said petition to the Public Works Department and shortly thereafter the city retained Black and Veatch Consulting Engineers (B&V) to conduct an update to the 1996 Wastewater Collection System Master Plan that updated the available sewer capacity and limitations in the Kings Run Sewer Service Area which is a sewer service �rea tributary to Lift Station 4; and, WHEREAS, the Public Works Department directed B&V to prepare Kings Run Analysis, dated November 14, 2002, which concluded that certain segments of the existing trunk sewer lack sufficient capacity to serve the portion of the Kings Run Sewer Service Area lying east of 60th Avenue N.W., and the cost to construct a parallel relief sewer line to serve this area would be approximately $2,608,380; and, WHEREAS, the Public Works Department also directed B&V to prepare a Supplemental Analysis to the Kings Run Analysis to determine the required trunk sewer capacities to serve an additional 2,300 acres lying west of 60th Avenue N.W.; and, WHEREAS, the B&V-prepared Supplemental Analysis, dated January 15, 2003, concluded that all segments of the existing trunk sewer between Lift Station 4 and the Douglas Trail lacked sufficient capacity to serve the additional 2,300 acres lying west of 60th Avenue N.W., and the cost to construct a parallel relief sewer line to serve this area would be approximately $3,471,374; and, WHEREAS, on October 27, 2003, the City Council received a report on the various Lift Station 4 replacement / relocation alternatives, as prepared by the team of HR Green and CH2MHill Consulting Engineers, which relied upon and incorporated the results / findings of B&V Kings Run Analysis, dated November 14, 2002 and the Supplemental Analysis, dated January 15, 2003;
