Inspection of SWM Practices Associated with Approved Credit
It is an owner's responsibility to inspect and repair their practices to ensure that they are functioning as designed and detailed in the approved credit application. In addition, the County reserves the right to inspect, at any time, stormwater management practices applied toward receiving a credit. Those inspections will be in accordance with an executed Inspection and Maintenance Agreement for Private Stormwater Management.
If there is no executed Inspection and Maintenance Agreement, the County may require the execution of a Right of Entry Agreement upon this issuance of a credit. Complete inspection information is available in the Stormwater Fee Credit Program Policy and Guidance document for Anne Arundel County.
Inspections and documentation are the primary methods employed to monitor approved credits.
Failure to maintain and operate the stormwater management practice in strict compliance with County Approved Plans, Maintenance Agreements, County Standards, Stormwater Management Practices and Procedures Manual
, and/or the 2000 Maryland Stormwater Design Manual, Volumes I and II, and Supplements
will result in the loss of the credit.
