Capital Improvements Program
Engineering staff manages the City's Street Capital Improvements Program (CIP) and the Water & Wastewater CIP. The Street CIP consists of bond programs that the voters and/or City Council approve.
The Water and Wastewater CIP is developed from the City's water and wastewater master plans. Bond programs follow a one or two year cycle. Projects include water mains, sewer mains, elevated water storage tanks, and pump stations. Water treatment plant expansions are managed by the Director of Water Utilities. Follow this link for the Water Master Plan and the Wastewater Master Plan, both were completed in 2019.
There is not a prequalification process for contractors to bid CIP projects. However, the City will investigate a contractor's financial stability, experience, and ability to perform upon successful bid.
Residential & Commercial Development
The Engineering Department oversees all public works infrastructure on private development projects. Staff reviews plans and inspects construction for streets, drainage, water and wastewater. All building permits are reviewed by the Engineering Department for compliance with public works standards. Mansfield collects Roadway Impact Fees, and Water and Sewer Impact Fees for new developments. In accordance with the Subdivision Control Ordinance, financial surety must be submitted for all public infrastructure on development projects before a final plat will be recorded. Prior to beginning construction of public infrastructure the following must be submitted to the Project Manager:
- Executed copy of contract including itemized proposal for public infrastructure
- Performance and Payment Bonds naming the City of Mansfield "dual obligee" (if public infrastructure exceeds $25,000)
- Two-year 100% Maintenance Bond on City's form

The Engineering Department also inspects underground private fire lines in cooperation with the Fire Department. Fire Protection System work may require a separate permit from the Fire Marshal's office. Engineering staff also inspects private water and sewer systems for projects such as apartment complexes or office parks in cooperation with the Building Safety Department.
