West Orange City Zoning Code
§ 25-29.3
Design and Performance Standards for Stormwater Management Measures.
[Amended 5-20-2025 by Ord. No. 2918-25]
a.
Stormwater management measures for major development shall be designed to provide erosion control, groundwater recharge, stormwater runoff quantity control, and stormwater runoff quality treatment as follows:
1.
The minimum standards for erosion control are those established under the Soil and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules at N.J.A.C. 2:90.
2.
The minimum standards for groundwater recharge, stormwater quality, and stormwater runoff quantity shall be met by incorporating green infrastructure.
b.
The standards in this section apply to all major and minor development and are intended to minimize the impact of stormwater runoff on water quality and water quantity in receiving water bodies and maintain groundwater recharge. The standards do not apply to new major development to the extent that alternative design and performance standards are applicable under a regional stormwater management plan or water quality management plan adopted in accordance with Department rules.
c.
Stormwater management measures for minor development shall be designed to provide erosion control, groundwater recharge and stormwater runoff quantity control through the utilization of green infrastructure techniques as follows:
1.
Stormwater management facilities shall be designated to manage six inches of rainfall on all new impervious surfaces and meet the standards for runoff quantity and green infrastructure.
2.
Soil testing shall be performed in accordance with the current rules at N.J.A.C. 7:8.
3.
The minimum standards for erosion control established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules at N.J.A.C. 2:90 shall be met.
4.
Regular and effective maintenance shall be performed for all stormwater management facilities and shall be protected by the owner.
d.
Note: Alternative standards shall provide at least as much protection from stormwater-related loss of groundwater recharge, stormwater quantity and water quality impacts of major development projects as would be provided under the standards in N.J.A.C. 7:8-5.
