West 32nd Street Detention Basin Bidding Initiation~ Dubuque T~~ cl rY o~ ~~ ..-- - ~j '~j~ ~ AID-an~riaci~ 1..J LJ -~- Masterpiece ot~ the Mississippi 2007 TO: The Honorable Mayor and City Council Members FROM: Michael C. Van Milligen, City Manager SUBJECT: West 32nd Street Detention Basin Project DATE: February 12, 2008 City Engineer Gus Psihoyos is recommending authorization of the public bidding procedure for the West 32"d Street Detention Basin Project and setting a public hearing for March 3, 2008. In December of 2001, the Dubuque City Council formally adopted a stormwater planning study titled "Drainage Basin Master Plan" prepared by HDR Engineering. According to the study, approximately 1,150 homes and businesses in the Bee Branch watershed are at risk of flood damage. The Drainage Basin Master Plan identified three projects with the West 32nd Street Detention Basin that would reduce the threat of flood damage. They are the Carter Road Detention Basin, expansion of the existing West 32nd Street Detention Basin, and the construction of a new open waterway from 15th Street to 24th Street. The Carter Road Detention Basin was completed in the spring of 2004 for $1,100,000. The Drainage Basin Master Plan improvements are funded with a stormwater Fee. With the Fiscal Year 2009 budget recommendation, the fee would be $4.00 per month. In October of 2005, the City (;ouncil endorsed the use of two wet ponds within the proposed West 32nd Street Detention Basin project. With the ability to remove pollutants from stormwater together with the aesthetic, wildlife, and environmental functions they provide, wet p~~nds are one of the most prevalent best management practices throughout the Midwest. According to the U. S. Environmental Protection Agency, tens of thousands e:~cist nationally. They are effective at removing sediment, heavy metals, phosphorus, nitrogen, and pathogens from stormwater. A 2-acre wet pond is included within the proposed 10-acre West 32nd Street Detention Basin to meet the design requirement for a detention basin that incorporates features to minimize maintenance activities required to keep the facility operating at an optimum level and to provide an area to collect sediment and debris for easy removal. As designed, the West 32nd Street Detention Basin will provide the maximum amount of storage possible given the available land area. The principal design event that the basin was sized to control is the 100-yr, 24-hour rain; however, the design ha:> been optimized to reduce discharge rates from events of lesser severity as well. The peak flow of runoff into the detention basin due to a 5-year rain will be 509 cubic feet peer second while the outflow will be only 209 cubic feet per second. That is a 59% reduction. The peak flow reduction for the 100-year rain is almost 70%. The detention t~asin will be able to store in excess of 33.5 million gallons (102.8 acre-feet) of stormwai:er. The design includes the planting and establishment of wild flowers and prairie grass throughout the basin. Construction of the West 32nd Street Detention Basin involves the excavation of approximately 105,000 cubic yards of soil of which about 75,000 cubic yards must be hauled from the site. Work includes the construction of an earthen embankment and installation of large diameter storm sewer: 96 feet of 108-inch diameter, 190 feet of 96- inch diameter, and 235 feet of 66-inch diameter reinforced concrete pipe. It also includes the installation of 328 feet of 24-inch diameter ductile iron pipe sanitary sewer. Finally, it includes the construction of a twin, 9-foot wide by 8-foot high box culvert to replace the bridge just east of Wildwood. I concur with the recommendation and respectfully request Mayor and City Council approval. ~~ ~ Michael C.
