About this project

ARPA Grant: $275,000 Approved: December 21, 2022 The City of Portsmouth will use ARPA grant funds to increase resilience of the Peirce Island wastewater treatment facility by elevating an approximately 400-foot section of the access road and the adjacent parking area by up to three feet and above the current 100-year floodplain. An overall reduction in impervious surfaces within the floodplain will also be achieved by replacing the packed gravel parking area with grass pavers and vegetation, improving stormwater management.
