2. The upsizing of the existing 18” X 36” ERCP drainage pipe and outfall to a 38” X 60” ERCP.

3. The removal of the existing 18” reinforced concrete pipe (RCP), and replacing it with 38” X 60” ERCP.

4. The upsizing of the existing inlet structure.

5. The removal and replacement of one (1) existing headwall.
