A. Policy Statement.
| |||||||
In filing an application for general development plan, preliminary major subdivision or preliminary major site plan, the Applicant shall comply with the following stormwater management requirements: | |||||||
Flood control, groundwater recharge, and pollutant reduction through nonstructural or low impact techniques shall be explored before relying on structural Best Management Practices (BMPs). Structural BMPs should be integrated with nonstructural stormwater management strategies and proper maintenance plans. Nonstructural strategies include both environmentally sensitive site design and source controls that prevent pollutants from being placed on the site or from being exposed to stormwater. Source control plans should be developed based upon physical site conditions and the origin, nature, and the anticipated quantity or amount of potential pollutants. Multiple stormwater management BMPs may be necessary to achieve the established performance standards for water quality, quantity, and groundwater recharge. | |||||||
B. Purpose.
| |||||||
To protect the public health, safety and welfare of the citizens of the Township of Roxbury and the surrounding communities by establishing minimum stormwater management requirements and controls for "major and minor developments," as defined in 13-8.401. These provisions are deemed necessary and essential in order to: | |||||||
1. Maintain the adequacy of natural stream channels and prevent accelerated bank erosion by controlling the rate and velocity of runoff discharge to these watercourses.
| |||||||
2. Prevent disruption of the stream vegetation caused by excessive flushing and sedimentation.
| |||||||
3. Prevent degradation of stream water quality due to impairment of the stream's biological function.
| |||||||
4. Enhance the quality of non-point runoff by water detention and/or retention measures.
| |||||||
5. Preserve present adequacy of culverts and bridges by suppressing artificially induced flood peaks.
| |||||||
6. Reduce public expenditures for replacement or repair of public facilities resulting from artificially induced flood peaks.
| |||||||
7. Prevent damages to life and property from flooding resulting from excessive rates and velocities of runoff.
| |||||||
8. Prevent the degradation of property by enhancing the environmental character of the streams of the Township.
| |||||||
9. Provide a means to remove pollutants from stormwater runoff through filtration.
| |||||||
10. Preserve the existing groundwater recharge potential of a site.
| |||||||
C. Applicability.
| |||||||
1. This ordinance shall be applicable to all site plans and subdivisions for the following developments that require preliminary or final site plan or subdivision review:
| |||||||
a. Non-residential major developments; and | |||||||
b. Non-residential minor developments; and | |||||||
c. Aspects of residential major developments that are not pre-empted by the Residential Site Improvement Standards at N.J.A.C. 5:21. | |||||||
2. This ordinance shall also be applicable to all major developments undertaken by the Township of Roxbury.
| |||||||
D. Compatibility with Other Permit and Ordinance Requirements.
| |||||||
Development approvals issued for subdivisions and site plans pursuant to this ordinance are to be considered an integral part of development approvals under the subdivision and site plan review process and do not relieve the Applicant of the responsibility to secure required permits or approvals for activities regulated by any other applicable code, rule, act, or ordinance. In their interpretation and application, the provisions of this ordinance shall be held to be the minimum requirements for the promotion of the public health, safety, and general welfare. This ordinance is not intended to interfere with, abrogate, or annul any other ordinances, rule or regulation, statute, or other provision of law except that, where any provision of this ordinance imposes restrictions different from those imposed by any other ordinance, rule or regulation, or other provision of law, the more restrictive provisions or higher standards shall control. | |||||||
E. Review and Approval.
| |||||||
The Board's consideration of applications may be guided by, but not limited to, the following factors: | |||||||
1. The suitability of the Applicant's proposed Stormwater Management measures, devices and planning techniques, whether involving on-site or off-site measures, or some combination thereof, in respect to the total surface runoff, velocities and rates of discharge which the Applicant's proposed construction or land disturbance may generate.
| |||||||
2. Existing topography, present vegetation and hydrologic soil factors, as shown on maps entitled "Hydrologic Soils, USDA Soil Conservation Service," subject to field verification.
| |||||||
3. Groundwater recharge and discharge areas and wet soils, subject to field verification.
| |||||||
4. Seasonal high groundwater table as determined by on-site soil evaluation and groundwater study.
| |||||||
5. The design storm.
| |||||||
6. Natural drainage flow and patterns throughout the sub watershed(s) affected by the plan.
| |||||||
7. Land uses in both the immediate vicinity and surrounding drainage region.
| |||||||
8. Any other applicable or relevant environmental and resource protection ordinance, statutes and regulations.
