Marley, P.E., Public Works Director SUBJECT: Engineering Services Agreement with Blank, Wesselink, Cook& Associates for Nelson Park Neighborhood Storm Sewer Design City Project 2012-22 SUMMARY RECOMMENDATION: It is recommended that the City Council approve the attached resolution authorizing the Mayor to execute, and the City Clerk to attest, a Professional Engineering Services Agreement between the City of Decatur and Blank, Wesselink, Cook& Associates (BWC) for design services for design of a storm drainage system and sanitary sewer separation project in the Nelson Park Neighborhood for a fee not to exceed $147,000. PRIOR COUNCIL ACTION: May 7, 2012 —City Council approved Resolution R2012-102, authorizing an agreement with BWC to begin the preliminary design for the Nelson Park Neighborhood Storm Sewer Design project for a fee not to exceed$80,513. BACKGROUND: Storm Sewer Priorities The 2009 Stormwater Master Plan addresses three main topics: 1. Stormwater Problem Area Prioritization 2. Regulation, Standards, and Policies 3. Stormwater Expenditures and Funding Mechanisms In April, 2014, the City Council approved a Stormwater Utility to provide a dedicated funding source to improve known drainage problems and to improve maintenance on existing stormwater facilities. The Nelson Park Neighborhood Storm Sewer design project addresses item 1 above by targeting the Nelson Park Neighborhood's ongoing storm drainage problems which were identified as the#2 storm water mitigation priority in the City's stormwater master plan. This project will also separate sanitary sewage from storm water drainage. Separating the two types of sewer flow will reduce or eliminate combined sewer overflows into the Sangamon River. Page � 1
