Lois Rem, 1670 Glenview Court, reported that a stray cat had recently been diagnosed as having a highly infectious disease and cautioned all cat and dog owners of the dangers ofletting their animals run at large. She urged animal owners to have their pets checked for this disease. There were no other public comments. UNFINISHED AND NEW BUSINESS A. Lift Station #11, BRW Options . Mr. Dwayne Stafford, Public Works Superintendent, explained that with the upcoming reconstruciton of Highway 96, a feasibility study has been done on eliminating Lift Station #11 at Arden Manor. This station serves all of the triangle area surrounded by Highways 10,96 and 1- 35W and all of the existing Round Lake commercial and industrial properties. With the upcoming reconstruction of Round Lake Road, staff felt it was an appropriate time to look at all options, including the elimination of Lift Station #11. Mr. Stafford advised that the City Engineer was asked to look at this and BRW has determined it would be possible to eliminate this lift station, but with significant project costs. He stated that while he would like to eliminate this lift station, he does not know if the project cost can be justified. Mr. Stafford reviewed the efforts of other neighboring communities in eliminating the number of lift stations they maintain and operate. . Mr. Greg Brown, City Engineer, used an overhead map to identij'y the location of this lift station and the three alternates as identified in the feasibility report. Alternate A maintains the current lift station in place and indicates the costs associated with daily and periodic maintenance, periodic capital improvements, construction of a complete new lift station in the first year of the analysis and that the pump station controls would be replaced at year 30 of the analysis. The total capitalized cost for Alternate A is $211,564.05. Alternate B includes the construction ofa gravity sanitary sewer main extending from the current location of Lift Station # 11 south approximately 4, I 00 feet to connect to an existing 21-inch City interceptor sewer which was recently constructed along 14th Street. The sewer would require casing pipe under Highway 96 in order to allow for future maintenance without disruption to the highway. The pipeline would then run along the east side of Round Lake Road and connect to an existing manhole at the intersection of 14th Street and Round Lake Road. The total capitalized cost for Alternate B is $358,780.10. Alternate C includes the construction of a gravity sanitary sewer main extending from the current location of Lift Station #11 south approximately 3,700 feet to connect to an existing City interceptor sewer recently constructed along 14th Street. The pipeline would run along the west side of Round Lake within a proposed easement to be dedicated along the eastern edge of the Gateway Business District properties and the U.S. Fish and Wildlife property surrounding Round Lake. The alignment would then run between the proposed Welsh Companies Phase III and Phase IV developments before connecting to the sewer in 14th Street. The total capitalized cost for Alternate C is $373,358.42.
