Dorchester County is Maryland’s second largest county and includes over 350,000 acres of wetlands, tidal marshes, creeks, and other low-lying lands. Around half of the county’s landscape lies at elevations below 4.9 feet, making it one of Maryland’s most at-risk counties to sea level rise. With financial and technical support from Maryland’s Coast-Smart Communities Initiative grant program, the county developed Sea Level Rise: A Technical Guidance for Dorchester County. This plan covers four planning phases and strategies: Vulnerability and Impact Assessment; Long-Range Comprehensive Planning; Codes, Regulations, and Development Strategies; and Public Education and Outreach. The county reviewed existing plans, development codes, regulations, and laws to ensure the necessary policies and codes were prepared for the reality of the county’s climate future impacts, specifically sea level rise and coastal storms.
