t . ri ' .0'1. PUSLit WORKS PUBLIC WORKS DIRECTOR INTERIM POLICY Stormwater Control in the Combined Sewer Area IPublic Works Policy#: 2-11 Supersedes Policy# 1-11 SUBJECT: Stormwater control in the combined sewer area. The combined sewer area shall be that described in the attached map or as updated by City of Everett Public Works Utility Mapping. BACKGROUND: Heavy storm events have caused localized surcharges in the City's combined sewer system,flooding basements and streets in North Everett. This flooding has been disruptive for citizens,causing damage to homes, creating health concerns, ' and imposing a financial burden on the rate-based utility. Controlling stormwater discharges to the combined sewer system would mitigate these impacts. EMC 14.56.020 authorizes the Public Works Director to adopt rules and procedures to implement chapters 14.56, Surface Water System, and 14.28, Surface and Storm Drainage. Pursuant to that authority, this policy modifies the City's Design and Construction Standards and Specifications(Section 4: Storm and Surface Water) and the City's 2010 Stormwater Management Manual by making application of the stormwater manual mandatory in the combined sewer area. EMC 14.08.135.A.3 authorizes the Director to establish rules for the administration of the sewer connection fees established by EMC 14.08.135.A.1. EMC 14.08.135.A.4 1 provides a basis for the exercise of the City's SEPA authority to require mitigation to supplement other code requirements. The Director in this policy exercises the authority granted by EMC 14.08.135.A.1, A.3, and A.4 to provide a credit against the sewer connection fee for the cost of stormwater controls that are in addition to those set forth in the Stormwater Management Manual.
