THE PLANNING PROCESS FOR LID - Low Impact Development and Sustainable Stormwater Management - page 89

Table 4-2 ( Continued )
• Special value areas?
• Wetlands?
• Floodplains?
• High-quality woodlands?
• Riparian buffers?
• Naturally vegetated swales, drainageways?
• Special sensitive areas?
• Steep slopes?
• Geologic constraints?
• High water table?
• Aesthetics?
• Air quality, noise, other issues?
• Size and shape of the site?
• Special constraints, opportunities?
• Site border conditions?
• Contiguous parcels?
• Upslope drainage?
• Existing areas of known/suspected contamination?
• Existing development features of site?
• Existing structures, if any?
• Preservation, restoration, historical value?
• Existing land cover?
• Existing impervious areas?
• Existing maintained areas?
• Existing infrastructure (water, sewer, storm drainage)?
• Other infrastructure (power, communication, energy)?
Constraints and Opportunities
• Constraint zones at site?
• Watershed issues?
• Special features?
• Opportunities (well-drained soils, etc.)?
Step 5 . Revision to Development Concept
Step 6 . Nonstructural LID Measures
Lot Configuration and Clustering
• Reduced individual lot size?
• Concentrated/clustered units/lots?
• Lots developed to avoid or preserve sensitive features?
• Lots configured to avoid earthwork, fit topography?
