East Orange, NJ Environmental Rules: Stormwater Management (2026)

East Orange City Code § 51-200A states the City's stormwater policy: flood control, groundwater recharge and pollutant reduction are to be achieved through green infrastructure best management practices (GI BMPs) and nonstructural stormwater management strategies, developed based on a site's physical conditions and the anticipated quantity of pollutants, sized to meet water quality, quantity and groundwater recharge performance standards. Subsection C(1) applies the article to nonresidential major developments and to the aspects of residential major developments not preempted by the state's Residential Site Improvement Standards at N.J.A.C.

5:21, and Subsection D(2) applies the same rules to the City of East Orange's own projects. Section 51-201 defines a 'major development' as one or more acres of land disturbance since February 2, 2004, a quarter acre or more of new regulated impervious surface since that date, a quarter acre or more of new regulated motor vehicle surface since March 2, 2021, or a combination of the two surface categories reaching a quarter acre. The article, which replaced a 2012 version adopted under Ordinance No.

4-2012, requires applicants to submit maintenance and inspection plans for their stormwater facilities under § 51-209 and lets the City require a performance or maintenance guarantee under N.J.S.A. 40:55D-53. A separate section, § 51-211, requires retrofitting existing private storm drain inlets that connect to the municipal separate storm sewer system whenever repaving, repair or reconstruction work touches them, to keep solids and floatables out of the system.
