1. Conservation Design for Subdivisions

2. 82 Acres of farmland - Growth of nearby city has led to sale for development.

3. Traditional Rural Subdivision
Ordinances often require minimum lot size of roughly 2 acres. Sometimes has to do with septic.
82 Acres subdivided into 32 lots at 2.3 acres (74 acres) leaving about 8 acres for roads.
The entire site is divided and owned individually by residents

4. Traditional layout of the 32 lots

6. Step 1a: Identify primary conservation areas

7. Step 1b: Identify secondary conservation areas

8. Step 2: Identify areas for development

9. House sites selected within area

10. Step 3: Layout roads and trails

11. Step 4: Decide on and draw lot lines

12. Conservation Design
32 lots at .7 acres (22 acres), roads 8 acres, 52 acres of open space
May require a “package plant” for sewer
Example of cluster development - concentrates developed area in favor of a commons or “public space” for amenity value

14. Potential Benefits Economic 1) smoother review process 2) lower costs
Environmental and cultural
Marketing and sales
Community and social
Provides “public” parkland
Greenway connectivity if adjacent properties are developed similarly
