Nashua, NH Tree Protection: Tree Removal Permits (2026)

There is no general private-lot tree-removal permit in Nashua's Revised Ordinances. The four regulatory triggers above operate through Chapter 190 (Land Use) and the City Charter. Article XI (Wetlands) imposes a Conservation Commission review for any tree removal in a wetland or buffer, with buffer widths of 20 feet (other wetlands), 50 feet (critical), 75 feet (prime), and 100 feet (vernal pool); the Conservation Commission submits recommendations to the Zoning Board or Planning Board on any wetlands application. NH DES wetlands review under RSA 482-A is independent of City review and is triggered by excavation, removal, filling, dredging, or construction in or adjacent to waters of the state. Article XXVII (Landscaping) governs trees required by approved site plans — removal requires Planning Department approval, and any dead or diseased required tree must be replaced in the next planting season. Trees designated for retention on an approved site plan, plat, or rezoning condition may not be removed without Planning Department approval. Trees standing in a Nashua street or public way fall under the full control of the Board of Public Works per the City Charter; removal requires Board approval. NH RSA 231:145 governs declaration and removal of hazardous highway trees and allows emergency removal without notice when delay would pose an imminent threat.
