SUBJECT: TPV 18-002 SAWS East Sewershed Large Diameter Package III
SUMMARY:
Request by Mr. Michael Persyn for approval of a tree preservation variance request from Unified Development Code 35-523 (h), "significant trees shall be preserved at eighty (80) percent and heritage trees at one hundred (100) percent preservation within both the 100-year floodplains and environmentally sensitive areas." This project will replace a 50 year old deteriorated sewer main and associated appurtenance within the Rosillo Creek and its floodplain. Due to the proposed scope of work, the project is unable to preserve the minimum 80% of significant trees within the 100-year floodplain and Environmentally Sensitive Area (ESA). The project will meet the required floodplain and Environmentally Sensitive Area mitigation by re-seeding all disturbed areas with a native seed mix to help return the ESA area to pre-development conditions.
