6. Private pumping systems may be required in buildings to provide adequate water pressure throughout the building. 7. Any impacts during construction may be mitigated with notices to property owners, businesses and residents. Alternate routes and phasing for transportation and pedestrian facilities may be implemented to ensure access on a daily basis. Construction schedules may be altered to occur during off-peak hours. B. Sewer and Stormwater 3.3 Mitigation Required by Existing Regulations 1. Department of Ecology The Washington State Department of Ecology has the authority to implement a water quality discharge permit, known as National Pollutant Discharge Elimination System (NPDES) permits, to regulate water quality. Since the system in the Downtown planning area consists primarily of combined sewers and discharges stormwater and sanitary sewer to the WPCF, the City is responsible for compliance with water quality standards at the facility. 2. City of Everett Similar to the City's regulatory requirements for public water, sewer facilities are regulated under the Municipal Code Title 14. Standards for construction, operation, billing rates and charges, and ownership and maintenance are detailed for stormwater and sanitary sewer facilities. Any work proposed within the City's right-of-way must be approved by a permitting process with the Utilities Department and must comply with the City of Everett's Design and Construction Standards and Specifications for Development manual. Standards for stormwater and sanitary sewer facilities are detailed in Section 4 Storm and Surface Water and Section 6 Sanitary Sewers respectively. 3.4 Mitigation Measures The following mitigation measures would reduce the impacts of development on the sewer system: 1. New developments and expansions must comply with the City of Everett's "Design and Construction Standards and Specifications Manual", Section 4 Storm and Surface Water and Section 6 Sanitary Sewers and NPDES permitting. 2. Stormwater connections associated with future development should connect into the existing trunk lines at the same locations as in the existing condition. 3. If a developer proposes to redirect stormwater connections to a different location it shall be the responsibility of the developer to ensure that there are no adverse impacts to the combined sewer system resulting from redirecting stormwater. 4. Conservation efforts should be implemented to reduce water use and wastewater generation. 5. Sewer modeling and analyses will be completed for each development and expansion project to determine the impact of the project and identify system improvements. 14
