Buffalo Permits and Local Rules

In Buffalo, any development must keep on-site trees of 6 inches DBH or more unless a listed exception applies, and soil disturbance of one-quarter acre (10,890 sq ft) or more requires a SWPPP as part of site plan review.

RuleWhat it means for your projectSource
SWPPP for one-quarter acre of disturbanceUnder Green Code Sec. 7.3.1, any land development that disturbs one-quarter acre (10,890 sq ft) or more, or less if part of a larger plan of at least one-quarter acre, must submit a Stormwater Pollution Prevention Plan prepared to Buffalo Sewer Authority requirements as part of site plan review. Smaller projects must still manage stormwater but do not need a SWPPP.Source
Tree conservation in development (6-inch DBH)Green Code Sec. 7.1.3 requires development to conserve on-site established trees (6 inches DBH or more). One may be removed only if it blocks a structure with no feasible alternative location, is damaging a structure, is diseased or injured beyond restoration, or is dead or hazardous; removed trees trigger replacement requirements.Source
Trees over 10 inches on permitted projectsFor any action requiring a City permit that may destroy live trees, a site plan showing existing trees is required, and removing any tree over 10 inches in diameter needs express written permission from the Parks Commissioner (Sec. 467-8). Replacement trees of equal combined diameter, or a payment to the Buffalo Urban Forest Fund, are required.Source
Public trees and hauling excavated soilCutting or removing any tree on a public street, park or public property needs the Commissioner’s authorization (Sec. 467-3). Hauling excavated material through city streets requires a permit from the Commissioner of Public Works (Sec. 169-6).Source
Call 811 before diggingExcavators and contractors must contact New York 811 (online ITIC or by calling 811) at least two working days but no more than 10 days before digging, not counting weekends and legal holidays.Source
Construction stormwater permitNYSDEC issues SPDES General Permit GP-0-25-001 for construction stormwater (effective Jan 29, 2025, expires Jan 28, 2030). Coverage is required for soil disturbance of one or more acres; 5,000 sq ft or more in the NYC East of Hudson watershed; and, inside New York City, 20,000 sq ft or more (or 5,000 sq ft or more of new impervious area), including smaller parts of a larger common plan of development.Source
Burning cleared brushStatewide, burning trash, leaves and treated or painted wood is banned. Downed limbs and branches under 6 inches in diameter and 8 feet long may be burned on site only in towns with fewer than 20,000 residents, and never from March 16 through May 14. Open fires of organic agricultural waste are allowed on contiguous farmland over 5 acres. The DEC page does not list land-clearing or construction debris as an allowed exception, so large land-clearing burn piles are not authorized by these rules.Source

Confirm requirements for your parcel with the city or county before work starts. See land clearing permits for a full checklist.

How to Choose an Excavation Contractor in Buffalo

Send every bidder the same plans and dimensions. Ask whether the price is per cubic yard, per hour or a fixed total; whether spoil haul-off, imported fill, rock and compaction testing are included; who handles permits and utility locates; and what the finished grade will look like.

For background before you call, read site preparation, excavation cost and land grading. If the site still has trees and brush, start with Buffalo land clearing contractors.

Frequently Asked Questions

What’s the difference between excavation and land grading?

Excavation digs out or moves earth to reach required depths. Land grading shapes the surface to set slope and drainage. Many sitework contractors do both, but quotes often price them separately.

How are excavation contractors priced?

By the cubic yard, by the machine-hour or as a fixed total. HomeGuide lists $2.50 to $15 per cubic yard for soil and $100 to $300 per hour for an excavator with an operator. Ask which unit a quote uses before comparing bids.
