Erosion and sediment pollution control plans shall
be prepared in accordance with the applicable BMPs and their design
standards listed in the Erosion and Sediment Pollution Control Program
Manual (E&S Manual), No. 363-2134-008 (March 31, 2012), as amended
and updated.

For example: If a property owner in Bucks County or Montgomery
County proposes a three-hundred-square-foot shed after adoption of
the Municipal Stormwater Management Ordinance, that property owner
would be exempt from site plan and peak rate control requirements.
If, at a later date, the property owner proposes to construct a garage
and driveway adding an additional 1,100 square feet of impervious
surface, the applicant would be required to submit a modified SWM
site plan (or a small project SWM site plan per Appendix 23-A, where
applicable) demonstrating the stormwater control requirements for
the total impervious surface of 1,400 square feet.
