The Zoning Ordinance of the City of South Portland, Maine, §27-1536 defines most of the City-level permit requirements regarding stormwater.
Levels of Permits:
There are three types of stormwater permits in South Portland, depending on what size and type of construction you are planning. From largest to smallest, they are:
- Post-Construction Stormwater Management Plan Covers major development activities that must go before the Planning Board.
- Basic Stormwater Management Plan: Covers minor development that must go before the Planning Board.
- Drainage Plan: This category is for small development activities which are not subject to site plan review.
Additional CSO Area Requirements:
In addition, South Portland’s Sewers and Drains Ordinance §22-24 restricts new connections to combined sewers, where they still exist in the City. Those restrictions help prevent combined sewer overflows (CSO’s).
