The agency is expected to invest $7m towards the initiative.

PENNVEST executive director Paul Marchetti remarked that works under the agreement will include augmenting the city’s storm water run-off infrastructure.

Lancaster Public Works director Charlotte Katzenmoyer added, "The projects will include porous pavement in parking lots, paths, alleys, and streets; infiltration and bio retention systems; green roofs; rain gardens; and rain barrels.

"Overall the projects will capture storm water runoff from a total of 951,000 square feet of impervious drainage area within the combined sewer district," added Katzenmoyer.

Constructions will be undertaken on public and private property and will collect storm water runoff to prevent it from entering into the combined sewer system.
