Site Design and Development Standards
Polluted runoff from impervious surfaces in your watershed affects the amount and the quality of water in your streams.





Site plans in residential, commercial, industrial zones, or anywhere else can protect local streams through good design. Site plans approved by local land use planning commissioners must comply with clearly stated development standards. Such standards are usually adopted as zoning, subdivision, or design regulations.When should site plans be used?
  • Preliminary approval or sketch plan
  • Final approvals
  • Stormwater Management Plan Approvals
  • Erosion Control/Grading Plan Approval and Construction Permits
Factoids
Do large lots protect open space and water resources? Large lots, both residential and commercial, and ''business parks' all require road frontage. The larger the lot, the longer the road and thus the more impervious surface. Talk to local real estate market experts: What built parcels hold the most value in your community?

Zoning and Subdivision standards: Learn more about Conservation Subdivision from the National NEMO Network and Natural Lands Trust. Download the NEMO Fact Sheet Many design solutions to protect open space or natural resources are possible: residential clustering, buffering streams, stormwater infiltration, built wetlands to treat wastewater and stormwater. On many sites, these solutions may result in lower net development costs, especially if standards are clear from the beginning or preliminary plan stages. Has your community adopted clear preliminary or sketch plan standards? For example, until recently, few local jurisdictions required wetland delineation at preliminary plan. After significant investments in engineering, local protestors opposed disturbance of such water resources only when they became aware of the proposed site plan at later hearings.


What other design standards protect water resources?
Your community's answer will most likely come from your experts--your local public works engineers, park or conservation staff, state or regional resources, local development professionals--and your citizens. To start, you will need a clearly stated goal: Protect your local waterways. You'll need to implement this goal with an action plan, your regulations, and processes. Here are some of the elements to consider:
  • Communication among the experts.
    Many local decision makers manage polluted runoff: planning commissioners, public works and engineering staff, parks and conservation staff and commissions. Each has a role and must understand how they cooperate to achieve your local goal.
