102-104 Washington Street

HLD provided site civil design for the 102-104 Washington Street project, an abandoned property obtained from the Newburgh Community Land Bank. The property consisted of two buildings sharing a party wall that could not be salvaged. The buildings will be demolished to allow for construction of a 4-story building consisting of 25 residential apartments and commercial space on the ground floor. HLD provided civil engineering support for the project that consisted of design of new water, sewer, gas and electric service lines to the building. The City of Newburgh has a combined sewer and stormwater system which experiences combined sewer overflows (CSOs) during rainfall events. The City of Newburgh required stormwater detention for this project because the combined sewer system experienced CSOs in the vicinity of the project. The building footprint covered the majority of the lot which prohibited any ground stormwater management. Therefore, HLD designed a building roof detention system “blue roof” to temporarily store stormwater before discharging it to the City combined sewer system to help minimize sewer system overflows from stormwater intrusion. HLD also designed a street tree bioswale to provide quality treatment and partial infiltration of street drainage. The site is currently under construction.
