Grading & Drainage: New Rochelle vs Yonkers

Can I regrade my yard?

Minor regrading typically doesn't need a permit, but you cannot redirect water onto neighbors or into the public right-of-way.

Does my New Rochelle home addition need a drainage plan?

Yes. New construction and major additions trigger Building and Engineering Department review of grading and stormwater drainage as part of the permit process.

What if my New Rochelle neighbor's regrading is flooding my yard?

Report it to the Building Bureau; directing runoff onto adjacent property violates city grading rules. You may also have a private nuisance claim under NY common law.

Can I regrade my backyard without a permit?

Minor landscaping yes; substantial regrading affecting drainage patterns requires Yonkers Engineering Department review.

Do I need a permit for a retaining wall in Yonkers?

Yes if the retaining wall exceeds 4 feet in height or sits adjacent to property lines. Engineered drawings and building permits are required under Yonkers Engineering Department rules.

Can I send my Yonkers stormwater runoff onto my neighbor's property?

No. Under Yonkers Code and NY common law, drainage must be managed on-site or directed to approved municipal storm drains. Discharging runoff onto neighbors or public ways is prohibited.
