Oneida, NY Environmental Rules: Stormwater Management (2026)

Section 143-22, Stormwater management, sits in Chapter 143's Article V, Special Procedures and Standards, and applies to every development that requires site plan approval under Section 143-9, meaning new construction, qualifying additions, and nonresidential or multifamily projects across the City's zoning districts. (1) ties stormwater design to the City's Comprehensive Plan and to applicable county, regional, and state storm drainage control programs, including Mosquito Commission Control Standards, and requires environmentally sound site planning and engineering techniques. (2) sets the performance standard: the developer must use the best available technology to minimize off-site runoff, increase on-site infiltration, encourage natural filtration, simulate natural drainage, and minimize off-site discharge of pollutants, naming retention basins, recharge trenches, porous paving and piping, contour terraces and swales as acceptable measures.

Subsection B leaves the specific engineering strategy and design to City specifications reviewed by the City Engineer. The Article VI document-specification rules that implement Section 143-22 also require, in the stormwater management report provisions immediately preceding it, storage and discharge calculations sized to two-year, ten-year and one-hundred-year, twenty-four-hour storm events, and a statement of whether a New York State Department of Environmental Conservation dam permit applies. Post-construction peak discharge rates may not exceed pre-construction rates. The Joint Zoning Board of Appeals/Planning Commission reviews these submissions as part of the site plan approval Sections 143-8 and 143-9 require, and the City Engineer signs off on the specific facility design and sizing before a permit issues.
