# N.J.A.C. 7:8 — Stormwater Management Rules Source revision: January 20, 2026. (f) The tables below summarize the ability of stormwater best management practices identified and described in the New Jersey Stormwater Best Management Practices Manual to satisfy the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards specified in this chapter. When designed in accordance with the New Jersey Stormwater Best Management Practices Manual and this chapter, the stormwater management measures listed in Tables 5-1, 5-2, and 5-3 shall be presumed to be capable of providing stormwater controls for the design and performance standards as outlined in the tables below. Upon amendment of the New Jersey Stormwater Best Management Practices Manual to reflect additions or deletions of BMPs meeting these standards, or changes in the presumed performance of BMPs designed in accordance with the New Jersey Stormwater BMP Manual, the Department shall publish in the New Jersey Register a notice of administrative change revising the applicable table.

(c) The precipitation depths of the current two-, 10-, and 100-year storm events shall be determined by multiplying the values determined in accordance with (c)1 and 2 below: 1. The applicant shall utilize the National Oceanographic and Atmospheric Administration (NOAA), National Weather Service's Atlas 14 Point Precipitation Frequency Estimates: NJ, in accordance with the location(s) of the drainage area(s) of the site. This data is available at: https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=nj; and 2. The applicant shall utilize Table 5-5 below, which sets forth the applicable multiplier for the drainage area(s) of the site, in accordance with the county or counties where the drainage area(s) of the site is located. Where the major development lies in more than one county, the precipitation values shall be adjusted according to the percentage of the drainage area in each county. Alternately, separate rainfall totals can be developed for each county using the values in the table below. Table 5-5: Current Precipitation Adjustment Factors | County | Current Precipitation Adjustment Factors | | | | --- | --- | --- | --- | | | 2-year Design Storm | 10-year Design Storm | 100-year Design Storm | | Atlantic | 1.01 | 1.02 | 1.03 | | --- | --- | --- | --- | | Bergen | 1.01 | 1.03 | 1.06 | | Burlington | 0.99 | 1.01 | 1.04 | | Camden | 1.03 | 1.04 | 1.05 | | Cape May | 1.03 | 1.03 | 1.04 | | Cumberland | 1.03 | 1.03 | 1.01 | | Essex | 1.01 | 1.03 | 1.06 | | Gloucester | 1.05 | 1.06 | 1.06 | | Hudson | 1.03 | 1.05 | 1.09 | | Hunterdon | 1.02 | 1.05 | 1.13 | | Mercer | 1.01 | 1.02 | 1.04 | | Middlesex | 1.00 | 1.01 | 1.03 | | Monmouth | 1.00 | 1.01 | 1.02 | | Morris | 1.01 | 1.03 | 1.06 | | Ocean | 1.00 | 1.01 | 1.03 | | Passaic | 1.00 | 1.02 | 1.05 | | Salem | 1.02 | 1.03 | 1.03 | | Somerset | 1.00 | 1.03 | 1.09 | | Sussex | 1.03 | 1.04 | 1.07 | | Union | 1.01 | 1.03 | 1.06 | | Warren | 1.02 | 1.07 | 1.15 |7.
