Checklist 1: Incorporation of Better Site Design Techniques

Example Checklist for Incorporation of Better Site Design Techniques
in Stormwater Management Plan

Applicant information
- Name, legal address, and telephone number
Common address and legal description of site
Vicinity map
Existing and proposed mapping and plans (recommended scale of 1" = 50'.) which illustrate at a minimum:
- Existing and proposed topography (minimum of 2-foot contours recommended)
- Perennial and intermittent streams
- Mapping of predominant soils from USDA soil surveys as well as location of any site-specific borehole investigations that may have been performed.
- Boundaries of existing predominant vegetation and proposed limits of clearing
- Location and boundaries of resource protection areas such as wetlands, lakes, ponds, and other setbacks (e.g., stream buffers, drinking water well setbacks, septic setbacks)
- Grading plan with location of existing and proposed roads, buildings, and other structures
- Location of existing and proposed utilities (e.g., water, sewer, gas, electric) and easements
- Location of existing and proposed conveyance systems such as grass channels, swales, and storm drains
- Flow paths
- Location of floodplain/floodway limits and relationship of site to upstream and downstream properties and drainages
- Location and dimensions of proposed channel modifications, such as bridge or culvert crossings
- Location, size, maintenance access, and limits of disturbance of proposed structural stormwater management practices
- Location of proposed community recreation/open space areas
- Landscape plan

Narrative and supporting calculations describing:
- Zoning, acreage, types and amounts of land uses (e.g., parking spaces, density, green areas, building footprint areas, etc.)

Traffic analysis estimating average daily trips for street network and parking requirements
Site impervious area
Reforestation and/or resource conservation protection measures
Comparison of proposed development data with allowable density, land use, etc.
Representative low-impact development techniques (with supporting evidence that technique is compatible with site characteristics) such as on-lot bioretention, tree clearing minimization, minimizing directly connected impervious surfaces, open section roads (also called roadside swales), etc.
Development phasing or implementation sequence
