Drainage Assistance


Evaluation Criteria

Response by DTE will begin after receiving your request. After all the necessary information about the request is received, the following steps are taken:

  • Investigate the nature and cause of the problem.
  • Determine if it should be included as a DAR Project, or
  • Refer to another appropriate agency responsible for this issue.
  • If a DAR project, calculate the size of the watershed, where the water originates and surface water flow characteristics.
  • Verify the number of properties being affected and extent of damage being caused by runoff, as well as cost/benefit ratio.
  • Review the existing drainage system in the area and potential needs for upgrades.
  • Determine availability of Right-of-Way or easements and needs for easements.
  • Determine if the problem can have a "spot solution" or a comprehensive Capital ImprovementProject (CIP) is needed.
  • If a "spot solution," develop design and schedule work with a construction contractor.
  • If a CIP, prioritize and include in the list of projects for recommendation as CIP projects for County Executive and County Council approval.
  • Notify the citizen what action is being taken.
