GIS Data Integration & Spatial Analysis

The contract seeks to integrate geographic information system (GIS) impervious area data with the City’s Tyler ERP and Assessor’s database to enable accurate billing and reporting for stormwater management and property-related fees. This integration will align spatial data on impervious surfaces—such as rooftops, driveways, and parking lots—with financial and property records to ensure equitable charge allocation based on actual surface coverage, improving transparency and compliance with regulatory requirements. The work will require precise spatial analysis, data mapping, and system interoperability to ensure seamless data flow and ongoing accuracy between the GIS platform and the core municipal databases. This subcontract is open for bids with a response deadline of June 3, 2026, and falls under NAICS code 541370 for other scientific and technical consulting services. The contracting entity is the Department of Public Works for the City of Portsmouth in New Hampshire, though specific location and point of contact details are not provided. The project is critical for modernizing municipal billing infrastructure and enhancing operational efficiency by automating data synchronization between land use characteristics and financial systems, ultimately supporting better resource management and regulatory reporting.
