Eastside Interceptor Section 2 Rehabilitation Page 5 of 7 June 27th, 2018 K:\Preapps\2018\PRE18-000389_Eastside Interceptor Section 2 Rehabilitation DEPARTMENT OF COMMUNITY & ECONOMIC DEVELOPMENT M E M O R A N D U M DATE: June 27, 2018 TO: Pre-Application File No. 18-000389 FROM: Alex Morganroth, Associate Planner SUBJECT: Eastside Interceptor Section 2 Rehabilitation General: We have completed a preliminary review of the pre-application for the above-referenced development proposal. The following comments on development and permitting issues are based on the pre-application submittals made to the City of Renton by the applicant and the codes in effect on the date of review. The applicant is cautioned that information contained in this summary may be subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner, Community & Economic Development Administrator, Public Works Administrator, Planning Director, Development Services Director, and City Council). Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. The applicant is encouraged to review all applicable sections of the Renton Municipal Code. The Development Regulations can be found online at www.rentonwa.gov. Project Proposal: King County Wastewater is proposing to rehabilitate the Eastside Interceptor Section 2, a 96- inch reinforced concrete pipe used for sewage flow running primarily within the Logan Ave N right-of-way (ROW) between Lake Washington Blvd N and Burnett Ave N. According to the applicant, severe corrosion caused by a hydrogen sulfide gas byproduct has damaged the pipe. The project would include the establishment of two staging areas adjacent to Logan Ave N (one near N 8th St and the other near Garden Ave N, the relining of the entire 3,900 feet long pipe using a Linabond lining system, and installation of a temporary bypass system to reroute flows through during the lining process. The temporary bypass pipe will be installed using a combination of shallow trenching (890 LF), standard trenching (175 LF), overland installation on-grade (1,700 SF), and racked installation (1,425 LF) depending on location. A trenchless method would be utilized for the rehabilitation in order to minimize the impact to the ROW and surrounding properties. The North Bypass System staging area near the intersection of Park Ave N and Garden Ave N would be located on a parcel owned by Boeing and would include as many as eight (8) primary and two (2) backup electric driven pumps to divert the sewage flow from the interceptor pipe into the temporary bypass pipe. Odor at the bypass site would be controlled via a tent structure over the open trench and an on-site modular, prefabricated air extraction and activated carbon odor control system. According to the applicant, construction on the pipe would last approximately eight (8) months. Access agreements with the City of Renton, Boeing, ITF Developments, LLC, and The Landing LLC would be required for project. Current Use: The Eastside Interceptor Section 2 is a portion of wastewater trunk line owned by King County Wastewater. The various land uses impacted by the project including manufacturing (Boeing), commercial, and City ROW. Development Standards: Development standards would not be applicable because of the nature of the subject project. Eastside Interceptor Section 2 Rehabilitation Page 6 of 7 June 27th, 2018 K:\Preapps\2018\PRE18-000389_Eastside Interceptor Section 2 Rehabilitation Zoning: The entire area of work has a Comprehensive Plan designation of Commercial Mixed Use and is zoned UC, Urban Center. The subject pipe is classified as a “major utility” per the Renton Municipal Code. Major utilities are an administrative conditional use in the UC zone. The proposed use (large utilities) would not be changing in capacity and would therefore not require a new or amended conditional use permit. A Tier 2 Temporary Use Permit would be required for the two proposed staging areas. Temporary Use Permit decision are based on consideration of the following factors: 1. The temporary use will not be materially detrimental to the public health, safety, or welfare, nor injurious to property or improvements in the vicinity of the temporary use; and 2. Adequate parking facilities and vehicle ingress and egress are provided to serve the temporary use and any existing uses on the site; and 3. Hours of operation of the temporary use are specified, and would not adversely impact surrounding uses; and 4. The temporary use will not cause nuisance factors such as noise, light, or glare which adversely impact surrounding uses; and 5. If applicable, the applicant has obtained the required right-of-way use permit. Noise Variance: A noise variance is required A public hearing shall be required for all noise variances which are greater than two (2) days in duration. For those variance requests of two (2) days or less in duration, the variance decision shall be made by the Administrator or his/her designee following the public notice process. 1. That the applicant suffers practical difficulties and unnecessary hardship and the variance is necessary because of special circumstances applicable to the applicant’s property or project, and that the strict application of this Chapter will deprive the subject property owner or applicant of rights and privileges enjoyed by others. 2. That the granting of the variance will not be materially detrimental to the public health, welfare or safety, or unduly injurious to the property or improvements in the vicinity of the location for which this variance is sought. 3. That the variance sought is the minimum variance which will accomplish the desired purpose. 4. That the variance contains such conditions deemed to be necessary to limit the impact of the variance on the residence or property owners impacted by the variance. 5. The importance of the services provided by the facility creating the noise and the other impacts caused to the public safety, health and welfare balanced against the harm to be suffered by residents or property owners receiving the increased noise permitted under this variance. 6. The availability of practicable alternative locations or methods for the proposed use which will generate the noise. 7. The extent by which the prescribed noise limitations will be exceeded by the variance and the extent and duration of the variance. Critical Areas: The subject pipeline work is located within a High Seismic Hazard area. As such, a geotechnical report would be required at the time construction permit submittal. It is the applicant’s responsibility to ascertain whether any additional critical areas or environmental concerns are present on the site during construction. Environmental Review: The project is Categorically Exempt from Environmental (SEPA) Review. Per WAC 197- 11-800, the repair or maintenance of public or private utilizes is exempt from SEPA review. Eastside Interceptor Section 2 Rehabilitation Page 7 of 7 June 27th, 2018 K:\Preapps\2018\PRE18-000389_Eastside Interceptor Section 2 Rehabilitation Permit Requirements: The proposal would require a Tier 2 Temporary Use Permit. The applications would be reviewed concurrently in an estimated time frame of 2-3 weeks once a complete application is accepted. Tier 2 Temporary Use Permit fee is $105.00 ($100 plus 3% Technology Surcharge Fee).
