Stormwater Management Manual
The 2016 Stormwater Management Manual revisions became effective on February 1, 2016. For projects that applied under the previous regulations, the following deadlines must be met:
- Grading Permit Application submitted to the Metro Stormwater Design Review Section by: 1/29/16, and
- Grading Permit Application passes Sufficiency Review by: 3/31/16, and
- Grading Permit Application passes Technical Review (approved) by: 7/31/16
Reminder: After Technical Review approval, a site will have 6 months to attend a Pre-construction meeting and then 6 months from the date of the Pre-construction meeting to obtain a Grading Permit. Failure to meet those time frames will result in the Technical Review/Plans approval being “expired” (per Stormwater Management Manual Vol. 1 - Section 4.3.4).
