The City's lot grading standards require that all lots in new subdivisions conform to an approved Surface Drainage Plan (Lot Grading Plan).

(Sample Only of an approved Surface Drainage Plan)

Approval for grading must be obtained at two stages during lot development. Generally, the homebuilder is responsible for obtaining Rough Grade Approval, and the homeowner is responsible for the Final Grade Approval.

The following guidelines help to ensure that your lot and building meet the conditions for lot grading approvals:

•  Service Connection
•  Design Grades
•  Minimum Grade from Foundation Walls
•  Drainage Swales
•  Backfill at Back of Concrete Walks or Paved Lanes
•  Downspouts
•  Sump Pump Discharge
•  Splash Pads
•  Discharge Points
•  Grading for Detached Garages or Building
•  Lot Grading Certificates
•  Lake, Ravine, or Top of Bank Lots
•  Sprinkler Systems
•  Grade Differential
•  Maintenance and Enforcement

Note: When purchasing a home, you should check that the lot grading meets approval. Drainage Services will only release this information upon receiving a written request from a law or realty firm.
