§ 26-121. General Requirements.
   1.   No regulated activities shall commence until the municipality approves a plan, which demonstrates compliance with the requirements of this Part.
   2.   Plans approved by the Municipality shall be on site throughout the duration of the regulated activity.
   3.   The Municipality may, after consultation with DEP, approve alternative methods for meeting the State Water Quality Requirements other than those in this Part, provided that they meet the minimum requirements of, and do not conflict with, State law including, but not limited to, the Clean Streams Law.
   4.   For all regulated activities equal to or greater than 1,000 sq. ft. in area, implementa tion of peak rate controls and preparation of a SWM Site Plan are required, unless exempted by § 26-122 of this Part. Please note that a pre-design conference shall be required to discuss the design and implementation of peak rate controls, and the preparation of a SWM Site Plan, unless waived by the Township Engineer. Also note that both the applicant and the qualified professional must attend this pre-design conference. The qualified professional will be provided with a copy of the Municipal ity's applicable stormwater management design manual at this pre-design conference.
   5.   Impervious Areas.
      A.   The measurement of impervious areas shall include all of the imperious areas in the total proposed development even if development is to take place in stages.
      B.   For development taking place in stages, the entire development plan must be used in determining conformance with this Part.
      C.   For projects that add impervious area to a parcel, the total impervious area on the parcel is subject to the requirements of this Part.
   6.   Discharges onto adjacent property. Permission of the adjoining property owner(s) shall be required when a SWM Plan proposes a concentrated discharge where none currently exists. In addition, permission of the downstream property owner(s) may be required by the Township if in the opinion of the Township Engineer, the downstream property owner(s) are being significantly impacted by the proposed SWM Plan.
   7.   All regulated activities shall include such measures as necessary to:
      A.   Protect health, safety, and property.
      B.   Meet State water quality requirements as defined in Part 1B.
      C.   Meet the water quality goals of this Part by implementing measures to:
         (1)   Minimize disturbance to floodplains, wetlands, natural slopes over 15 percent, and existing native vegetation.
         (2)   Preserve and maintain trees and woodlands. Maintain or extend riparian buffers and protect existing forested buffer. Provide trees and woodlands adjacent to impervious areas whenever feasible.
         (3)   Establish and maintain non-erosive flow conditions in natural flow pathways.
         (4)   Minimize soil disturbance and soil compaction. Cover disturbed areas with topsoil having a minimum depth of4 inches. Use tracked equipment for grading when feasible.
         (5)   Disconnect impervious surfaces by directing runoff to pervious areas.
      D.   Incorporate the techniques described in Appendix 26-A of this Part (Low Impact Development Practices) whenever practical.
   8.   The design of all facilities over Karst shall include an evaluation of measures to minimize adverse effects.
   9.   The design storm volumes to be used in the analysis of peak rates of discharge should be obtained from the Precipitation-Frequency Atlas of the United States, Atlas 14, Volume 2, US Department of Commerce, National Oceanic and Atmospheric Administration, National Weather Service, Hydrometeorological Design Studies Center, Silver Spring, Maryland, 20910. NOAA's Atlas 14 can be accessed at Internet address: http://hdsc.nws.noaa.gov/hdsc/pfds/.
   10.   All project sites shall be evaluated for the presence of wetlands. If wetlands are present, then the applicant shall obtain a jurisdictional determination from the USACE.
