A justification must be included in the SWM site plan if BMPs other than green infrastructure methods and LID practices are proposed to achieve the volume, rate, and water quality controls required under this chapter, the Township will not approve the SWM site plan unless it determines that green infrastructure and LID practices are not practicable.
A. 
The SWM site plan shall be submitted by the developer to the Township as part of the preliminary plan submission for the subdivision or land development.

If a longer notification period is provided by other statute, regulation, or ordinance, the applicant will be so notified by the Township.

Terms of validity shall commence on the date the Township signs the approval for an SWM site plan. If an approved SWM site plan is not completed according to § 296-35 within the term of validity, then the Township may consider the SWM site plan disapproved and may revoke any and all permits.
