The scope of services is a general guide to the work the City expects to be performed by the Consultant and is not a complete listing of all services that may be required or desired. The City is seeking professional services from a qualified firms for Construction, Engineering and Inspection (CEI) Services related to Phase II of the Southeast Drainage Project (hereinafter “Project” or “Site”). This project consists of various drainage improvement operations to provide relief from flooding to a low-lying area in the southeast section of the City. The Site is a fully-developed neighborhood that consists of approximately 500 single-family homes which appear to have been constructed between 1970 and 1995, with some subsequent renovations and newer construction. Water and sewer service lines are currently located within the front yards of each single-family home within the designated project area. Interruption of the services is to be avoided to the extent possible. The purpose of the Project is to address current flooding issues , Phase II encompasses the neighborhood bounded by SE 4th Street to the north, SE 2nd Avenue to the west, SE 7th Street to the south and SE 5th Avenue to the east. Within these limits, there are priority areas located at the current low spots that result in traffic disruptions and repeated private property losses due to flooding. The Project area is about 49 acres and is in a low-lying area within the basin, which receives runoff from the west. The Improvements should consider a contribution area of approximately 95 acres. The contributing area of 95 acres is bounded by SE 2nd St and SE 3rd Street to the north, state road US-1 to the west, SE 7th Street to the south and SE 5th Avenue to the east. The storm event to be modeled for the proposed solutions will be a storm event of 3-day duration and 25 year return frequency, with flooding duration of less than 6 hours, with less than 2 inches of flooding at the crown of the road. The Municipality is seeking drainage solutions (i.e. replacement of one pump station, drainage wells, exfiltration trenches, stormwater infrastructure, etc.) to reduce flooding, including duration and severity, reduce neighborhood impacts and mitigate project costs.
