​​​​​C. Stormwater Management – Programmatic Assessment Outline​

1. Watershed Protection and Planning Tools to Improve Local Stormwater Management Programs

• Model Stormwater Ordinance and Supplement​, Manage stormwater runoff through the use of nonstructural best management practices (BMPs) to the maximum extent practicable (MEP);
• Water Resource Manual and Regulatory Code (Carroll County example​);
• Using Critical Area Commission Intensive Development Guidelines Jurisdiction - wide 10% impervious surface area limitation;
  
• Montgomery County’s Sustainability Approach;
• Frederick County Model Development Principles
  

2. Protection Measures

​a. Streams and water resource protection

• Stream Buffer Plan
• Reforestation and Protection of Contiguous Forests
• Sensitive Areas Protection (see Sensitive Areas Element)

b. Sustainability

• Capturing and Reusing Stormwater Runoff
• ​​Criteria for Stormwater Harvesting, i.e., rain barrels and cisterns
• Design Consideration
• Calculating Stormwater Volume Reduction

• ​Meet Leadership in Energy & Environmental Design (LEED) Stormwater Management, Erosion & Sediment Control, and Landscaping Requirements​ 
  

c. Mapping

• Storm Drain Systems
• Stormwater BMPs
• Forest Coverage
• Streams, Rivers, etc.
• Water Quality Indicators
• Sensitive Areas
• Wetlands
• Endangered Species

3. Development Strategy​

• Avoidance
• Minimization
• Mitigation
