The City is exempt from the State's sales and use tax as well as all Federal excise taxes. The City of Portland Public Works Department desires to engage the services of an engineering firm to work with City Water Resources Engineering staff to develop the above referenced project. The engineering firm will be required to provide survey services to develop an existing condition plan for the project area, review the available CCTV and City of Portland record drawings within the project area, develop hydrologic and hydraulic (H&H) models of the existing combined sewer system, and provide recommendations for concept level sewer separation and green infrastructure projects in the watershed. The purpose of the project is to lay the groundwork for future green infrastructure and sewer separation projects in the Maple Street sewershed that will reduce the Citys combined sewer overflow at CSO 26 on the Portland Fish Pier. The Maple Street sewershed is an approximately 130-acre area in Portlands downtown district. It includes over 22,000 feet of sewer pipe, ranging in size from 10-inch to 45-inch diameter. It is a combined sewer area with minimal dedicated stormwater collection. When the capacity of the combined sewer is exceeded, it discharges at CSO 26 on Portland Fish Pier in Portland Harbor. In the past 5 years (2017-2021), annual discharge from CSO 26 has ranged from 4.385 million gallons to 25.719 million gallons. In those same 5 years, there have been 10-19 discharge events per year, and discharge has occurred in storms with as little as 0.09 inches of precipitation. The City of Portland seeks to reduce combined sewer discharges throughout the City, and is looking for opportunities to reduce discharges from the Maple St watershed. The method of contractor selection has not been determined at this time.
