30.70.310 Started construction – compliance with updated stormwater drainage regulations.
(1) The purpose of this section is to implement the requirement in the county’s National Pollutant Discharge Elimination System (NPDES) Phase I Municipal Stormwater Permit (Permit) that certain permits and permit applications must comply with updated stormwater drainage regulations, per the schedule and standards mandated by the Washington State Department of Ecology in the Permit. In the event this section conflicts with any other provision of Snohomish County Code, this section prevails.
(2) Approved permits and permit applications subject to pre-January 22, 2016, stormwater drainage regulations that have not started construction by July 1, 2021, must be revised by the project proponent to comply with updated stormwater drainage regulations that will be made effective by the county on July 1, 2021. For projects with a phasing plan, compliance with the started construction requirement will be assessed separately for each phase.
(3) Approved permits and permit applications subject to pre-July 1, 2021, stormwater drainage regulations in effect between January 22, 2016, and June 30, 2021, that have not started construction by July 1, 2026, must be revised by the project proponent to comply with updated stormwater drainage regulations that will be made effective by the county on July 1, 2021. For projects with a phasing plan, compliance with the started construction requirement will be assessed separately for each phase.
(4) For purposes of this section, "started construction" means either:
(a) the site work associated with, and directly related to the approved project is at a stage where rough grading is complete or utilities are installed. For rough grading to be considered complete, elevations are within one foot of final design elevations; or
(b) for public works projects performed under the authority of the director of public works or the county engineer which are subject to public bid laws, the project has been advertised per public bids laws, legislatively approved for construction, awarded to contractor, site work has begun, and the contractor has a schedule for completion.
(5) For purposes of this section, "stormwater drainage regulations" are as described in SCC 30.63A.100. (Added by Amended Ord. 21-008, Apr. 7, 2021, Eff date Apr. 22, 2021).
