Form-based codes, which regulate urban development by form and density, show promise for improving water quality. Effective implementation requires strong regional planning and experienced local government staff.
Area of Science:
- Environmental Science
- Urban Planning
- Environmental Policy
Background:
- Existing stormwater discharge regulations often fail to meet water quality standards.
- Land use planning and development regulations are crucial but often overlooked for stormwater management.
- Rapid growth in regions like the Jordan Lake Watershed exacerbates water quality challenges.
Purpose of the Study:
- To explore the role of form-based codes in achieving urban planning and water quality objectives.
- To assess the feasibility of form-based codes for reducing development impacts on water quality in the Jordan Lake Watershed.
- To examine legal feasibility, barriers, opportunities, and implementation challenges of form-based codes.
Main Methods:
- Exploratory case study in the Jordan Lake Watershed, North Carolina.
- Analysis of existing programs and regulations.
- Conducting interviews with relevant stakeholders.
Main Results:
- High-quality data and modeling are essential for consensus on water quality impairment.
- Experienced regional planning bodies with regulatory authority facilitate implementation.
- Local governments with experienced staff in complex ordinance implementation are better equipped.
Conclusions:
- Form-based codes offer a viable approach to integrating urban planning with water quality improvement goals.
- Successful implementation hinges on robust data, strong regional governance, and capable local administration.
- Addressing development impacts requires a shift towards regulating urban form and density.
