Franklin staff unveil draft natural‑resource compensation guide; commissioners flag tree replacement ratio

Planning staff presented a draft Natural Resource Impact Compensation Guide at the Parks & Environmental Commission meeting on Nov. 10. The administrative policy was prepared with Birchline Planning and is intended to give applicants clearer expectations for compensating habitat and tree loss required by the city’s Unified Development Ordinance.

Staff told the commission the draft clarifies how to evaluate impacts to trees, wetlands and buffers and what kinds of mitigation — such as replacement plantings and landscaping — the city expects. Staff also acknowledged a discrepancy in the draft’s Table 4 (page 15) that does not match the current UDO ratios and said the document remains a draft for commissioner review.

Several commissioners pressed the commission to consider restoring a more protective tree replacement ratio: under the recently adopted ordinance the replacement factor for a large tree is 0.75 trees; the prior ordinance used a 1.5 replacement factor, which commissioners said better reflects loss of mature canopy. Commissioners also discussed maintenance and financial guarantees, noting the draft’s maintenance surety language and debating whether a three‑year guarantee is preferable to a two‑year term.

Staff asked commissioners to submit written comments before the next meeting so staff can consolidate feedback and prepare a recommendation to the common council for adoption as an administrative policy if the commission endorses it.

Next steps: commissioners will review the draft text and the tree‑replacement math and return comments to planning staff; no policy was adopted at the Nov. 10 meeting.
