LOW DENSITY
DESIGN REQUIREMENTS FOR LOW DENSITY PROJECTS MOM 02N.1003
1 Is project below density thresholds set forth In the applicable stormwater rule? Yes
2 Does project maximize dispersed flow and minimize channelizatlon of flow? Yes
3 Has the use of piping been minimized per.1003(2)(c)? Yes
4 Side slopes of the vegetated conveyances(H:V) 3:1 Max
5 Maximum velocity in the vegetated conveyances during the 10-year storm? 1.27
6 Are curb outlet swales proposed? No
7 Maximum longitudinal slope of curb outlet swale(s)(%)
8 Bottom width of curb outlet swale(s)(feet)
9 Maximum side slope of curb outlet swale(s)(H:V)
10 Minimum length of curb outlet swale(s)(feet)
11 Are treatment swales used instead of curb outlet swales? No
12 Is stormwater released at the edge of the setback as dispersed flow? Yes
13 Have stormwater outlets been designed to prevent downslope erosion? Yes
14 Are variations to rule.1003 proposed? No
ADDITIONAL INFORMATION
15 'Please use this space to provide any additional information about this low density project
The project has onsite ditches around the parking area access roads which discharge to temporary sediment basins.In the final
grading plan(temporary sediment basins removed)the ditches are widened at the discharge point to disperse the flow to a sheet
flow scenario downstream.
