Existing radius is 350 feet.

power lines, etc.
3. Provide names of streets.
4. Provide a street lighting plan and a streetscape (landscaping) plan
along with details of brick pavers at entranceways to development.

6. Verification that storm sewer was designed using T?-40, for 100-year
storm frequency.

shall be 25' minimum.
