Title
2017 STORMWATER CODE UPDATE
COUNCIL STRATEGIC INITIATIVE ADDRESSED:
Provide sustainable water quality & environmental infrastructure
SUMMARY STATEMENT:
In order to comply with the City’s NPDES Phase II Municipal Stormwater Permit, staff has prepared an update of the stormwater regulations in Longview Municipal Code (LMC) Title 17, which specifies stormwater requirements for development and land disturbing activities, and prohibits illicit connections and discharges to the municipal storm sewer system.
The City last updated its stormwater codes in 2009 to comply with the 2007 Stormwater Permit. The 2012 Stormwater Permit included new requirements and provisions that require the LMC to be updated no later than June 30, 2017.
Staff reviewed the existing stormwater code in LMC 17.80 and proposes to separate those codes into two chapters, LMC 17.80 and 17.90, and update those sections to comply with the 2012 Stormwater Permit. As required by the 2012 Stormwater Permit and the LMC, these proposed code sections have been prepared in conjunction with the Longview Stormwater Advisory Committee (LSAC).
The 2012 Stormwater Permit also specifies that Low Impact Development (LID) best management practices be considered the preferred and commonly used method to control runoff and water quality at a project site. Staff proposed updates to LMC Titles 12 and 19 to allow greater flexibility for the use of LID practices. The proposed changes in LMC Titles 12 and 19 have been reviewed by the planning commission and are being presented to the city council as a separate item for consideration.
