Previous Questions

1. Proposed pump station location – Easement along Girl Scout Property

2. Sewer Connections made at time of project completion

3. Sewer fee charges start once property is connected to the system

4. If presented “street design” approach is accepted, trees, fences, etc. do not need to be removed. May need to temporarily remove some fencing then put back.

5. Spring Lane walking path – will work with Streets Dept. for best material
