(1) Construction. All construction and development shall minimize stormwater runoff from the site in excess of the natural pre-development conditions. Where possible, existing natural runoff control features, such as berms, swales, terraces and wooded areas shall be retained in order to reduce runoff and encourage infiltration of stormwaters.

(2) Maintenance. Stormwater runoff control systems shall be maintained as necessary to ensure proper functioning.
 

NOTE: The Stormwater Management Law (38 M.R.S.A. § 420-D) requires a full permit to be obtained from the DEP prior to construction of a project consisting of 20,000 square feet or more of impervious area or five acres or more of a developed area in an urban impaired stream watershed or most-at-risk lake watershed or a project with one acre or more of developed area in any other stream or wetland watershed. A permit-by-rule is necessary for a project with one acre or more of disturbed area but less than one acre impervious area (20,000 square feet for most-at-risk lakes and urban impaired streams) and less than five acres of developed area. Furthermore, a Maine construction general permit is required if the construction will result in one acre or more of disturbed area.

(3) Plan required. When required by the Code Enforcement Officer or the Planning Board, stormwater management plans shall be designed utilizing the most recent approved version of the Cumberland County Soil and Water Conservation District's "Maine Erosion and Sediment Control Handbook for Best Management Practices." Completed plans, when required above, may be reviewed by the Cumberland County Soil and Water Conservation District or other qualified group. Prior to the issuance of a building permit, the Code Enforcement Officer or Planning Board may require the applicant to obtain plan approval from the Cumberland County Soil and Water Conservation District.

(4) General. All activities within the shoreland zone are expected to employ appropriate stormwater management practices regardless of the zone or district they are located in.
