Source context and notes
New impervious surfaces at a development site can have the greatest adverse effect on groundwater recharge and stormwater quality and quantity. This section of the checklist helps identify those nonstructural strategies and LID-BMPs that have been incorporated into a proposed development's design to comprehensively manage the extent and impacts of new impervious surfaces. A. Specify impervious cover at site: Existing: ___________________________ Proposed: ___________________________ B. Specify maximum site impervious coverage allowed by regulations: ___________________________ C. Compare proposed street carway widths with those required by regulations: | Type of Street | Proposed Cartway Width (feet) | Required Cartway Width (feet) | | --- | --- | --- | | Residential access – low intensity | | | | Residential access – medium intensity | | | | Residential access – high intensity with parking | | | | Residential access – high intensity without parking | | | | Neighborhood | | | | Minor collector – low intensity without parking | | | | Minor collector – with one parking lane | | | | Minor collector – with two parking lanes | | | | Minor collector – without parking | | | | Major collector | | | D. Compare proposed parking space dimensions with those required by regulations: Proposed: ___________________________ Regulations: ___________________________ E. Compare proposed number of parking spaces with those required by regulations:2. Table 2¶

| No. | Nonstructural Strategy | Yes | No |
|---|---|---|---|
| 1. | Protect areas that provide water quality benefits or areas particularly susceptible to erosion and sediment loss. | ||
| 2. | Minimize impervious surfaces and break up or disconnect the flow of runoff over impervious surfaces. | ||
| 3. | Maximize the protection of natural drainage features and vegetation. | ||
| 4. | Minimize the decrease in the pre-construction time of concentration. | ||
| 5. | Minimize land disturbance including clearing and grading. | ||
| 6. | Minimize soil compaction. | ||
| 7. | Provide low maintenance landscaping that encourages retention and planting of native vegetation and minimizes the use of lawns, fertilizers, and pesticides. | ||
| 8. | Provide vegetated open-channel conveyance systems discharge into and through stable vegetated areas. | ||
| 9. | Provide preventative source controls. |
