Title
Authorizing the Mayor and the City Clerk to execute Amendment No.1 to the existing Purchase of Services contract between the City of Madison and Carollo Engineers for engineering services for the Campus, Downtown, and East Washington Ave Sanitary Sewer Study (District 2, District 4, District 5, District 6, District 8, District 12, District 13, District 15, District 17).
Body
The City of Madison is experiencing rapid population growth and redevelopment of properties throughout the City, particularly along its major transit corridors. This rapid increase in population density has increased demand on the wastewater collection system, operated and maintained by the City of Madison Sanitary Sewer Utility, within the Engineering Division. Portions of the system have known capacity limitations and increased population further increases demands. Each new large-scale residential redevelopment project requires extensive review and analysis to understand what system improvements are needed to accommodate the additional wastewater.
The City Engineer selected Carollo Engineers to complete a sanitary sewer study of the UW Campus, Downtown, and East Washington Ave areas of the city (RES-26-00087, Legistar #91577).
Engineering has requested additional services to support the study and recommends work be completed under the existing contract. These services include extending the sanitary sewer monitoring period to a period of three months to capture a wider range of system operating and weather conditions.
NOW THEREFORE BE IT RESOLVED that the Mayor and City Clerk are hereby authorized to execute an Amendment 1 to the contract between the City of Madison and Carollo Engineers, Inc for additional engineering services for the Campus, Downtown, and East Washington Ave Sanitary Sewer Study.
