Editor's Note: See Ch. 230, Zoning.
B. 
No stormwater will be permitted to drain across a street or across an intersection.
(1) 
The stormwater management system shall be designed to accommodate upstream drainage, accounting for existing conditions and approved or planned developments not yet built, and shall include a surplus design capacity factor of 25% for potential increases in upstream runoff. If evidence establishes that the stormwater system serves only the upstream area of a watershed, no more than 10% surplus design capacity is required.
(2) 
The storm drainage shall not be permitted to overload existing or future planned storm drainage systems downstream from the subdivision. The applicant shall be responsible for financing any improvements to existing drainage systems required to handle the increased storm flows.
C. 
Drainage plan. A drainage plan within the perimeter of the proposed subdivision shall be drawn to a scale of one inch equals 100 feet (1:1,200) and shall show the incremental areas contributing runoff to each catch basin, ditch or watercourse. The runoff plan shall also show existing and proposed contours at two-foot intervals. The contributing watershed areas outside the perimeter of the subdivision shall be drawn to a scale of one inch equals 200 feet (1:2,400) and shall be included in the calculations.
D. 
Design criteria. Refer to TDCSM for design criteria.
E. 
Erosion control.
(1) 
Except for surplus topsoil from roads, parking areas, and building excavations, topsoil is not to be removed from the site.
(2) 
Except for normal thinning, landscaping, and cutting of trees to provide access to direct sunlight, existing vegetation shall be left intact to prevent soil erosion on lots.
(3) 
To prevent soil erosion of shoreline areas, tree cutting in a strip paralleling the shoreline and extending 50 feet inland from all points along the normal high-water mark shall be limited in accordance with the following provisions:
(a) 
No more than 30% of the length of the strip shall be clear-cut to the depth of the strip.
(b) 
No clear-cut openings shall be greater than 30 feet wide.
(c) 
In the remaining 70% length of the strip, cutting shall leave sufficient cover to preserve natural beauty and control erosion.
F. 
Water quality. Any subdivision that will result in the creation or redevelopment of more than 10,000 square feet of impervious area such as roads, drives, walks, and roofs or one or more acres of disturbed area shall manage the quality of the stormwater runoff to meet the standards of Maine Department of Environmental Protection Chapter 500[3] and City of Saco Chapter 230, Zoning. Stormwater best management practices appropriate for the site and type of activity must be used to meet the standards specified in this section. Preference shall be given to use of nonstructural BMPs where feasible. The standards must be met at the property line or before the runoff enters a water body, whichever point is first reached by the runoff:
(1) 
Any subdivision located in the portions of the watershed of the Saco River that are upstream of the public water supply intake of Maine Water Company or that are located in the watershed of the Scarborough River, including tributaries of the Nonesuch River, Nonesuch Brook, Ricker Brook, Boynton Brook, Merrill Brook, Mill Brook, Stewart Brook, and Goosefare Brook, shall comply with the following additional requirements:
(a) 
Ditches, swales, and other open stormwater channels must be designed, constructed, and stabilized using erosion and sedimentation control best management practices that achieve long-term erosion control, and must receive adequate routine maintenance to maintain capacity and prevent or correct any erosion of the channel's bottom or side slopes.
(b) 
Gravel roads must be designed and constructed with crowns or other measures, such as water bars, to ensure that stormwater is immediately delivered to adjacent stable ditches or vegetated buffer areas. Grading of gravel roads, or grading of the gravel shoulders of gravel or paved roads, must be routinely performed to ensure that stormwater drains immediately off the road surface to adjacent buffer areas or stable ditches, and is not impeded by accumulations of graded material on the road shoulder or by excavation of false ditches in the shoulder.
(c) 
The project site must be maintained to prevent or correct erosion problems.
(2) 
Responsibility for subdivision drainage. The responsibility for adequate drainage shall rest with the developer. This shall include connection with existing drainage facilities, if any, provided by the City. When private drains are connected to City drainage, the City will not be responsible for any damage.
(3) 
All open and closed drainage systems shall be designed and installed in conformance with the TDCSM.
