Date of Decision: September 23, 2025
Mitigation Measures:
1. The project construction shall comply with the recommendations found in the submitted Geotechnical
Engineering Report with Infiltration Evaluation, prepared by Geo Group Northwest, Inc., dated May 14,
2018, and future addenda.
2. The applicant’s geotechnical engineer shall review the project’s construction and building permit plans
to verify compliance with the geotechnical report(s). The geotechnical engineer shall submit a sealed
letter to the Current Planning Project Manager stating that he/she has reviewed the construction and
building permit plans submitted to the City and in their opinion the plans and specifications meet the
intent of the report(s).
3. The geotechnical and structural design of the 4th Dimension Building , including the portion of the
building providing compensatory storage, must be prepared in a way that will prevent damage to the
subject building and surrounding properties resulting from seepage of water into the subbase materials,
as well as potential settlement and erosion that might occur. Possible means of accomplishing this
include providing a watertight concrete base slab and/or a waterproof liner beneath the open channel
and compensatory storage area to prevent infiltration of water into the subbase material. The project's
geotechnical and structural engineers must provide the City with a correspondence bearing a

professional engineering stamp stating that in their opinion the project as designed will not result in
property damage caused by settlement or erosion of the subbase material.
4. The applicant shall submit an Inadvertent Discovery Plan (IDP) prepared by a qualified professional with
the civil construction permit for review and approval by the Current Planning Project Manager prior to
permit issuance. In addition, the applicant shall provide notification to the Duwamish Tribe in the event
that archaeological work or monitoring is performed on-site.
5. A prorated share of the traffic signal costs shall be collected from the proposed project, based upon the
ratio of peak-hour vehicle trips that would be added by the project to the total project future baseline
trips at the NE 4th St and Bremerton Ave NE intersection. The fee would be calculated based on the
following formula: (New PM peak-hour trips) / (Total vehicle PM peak-hour trips for the signal) x (Cost of
new signal and improvements). The prorated share of the traffic signal is $15,686.27 ((40/3,060) x
1,200,000 = $15,686.27). The fee shall be paid prior to temporary certificate of occupancy.
The City of Renton Environmental Review Committee has determined that probable significant environmental
impacts from the proposed project can be mitigated. An Environmental Impact Statement (EIS) is not required
under RCW 43.21C.030(2)(c). Conditions were imposed as mitigation measures by the Environmental Review
Committee under their authority of Section 4-9-070D Renton Municipal Code. These conditions are necessary to
mitigate environmental impacts identified during the environmental review process. Because other agencies of
jurisdiction may be involved, the lead agency will not act on this proposal for fourteen (14) days.
Appeals of the environmental determination must be filed in writing on or before 5:00 p.m. on October 7, 2025.
Appeals must be submitted electronically to the City Clerk at cityclerk@rentonwa.gov or delivered to City Hall 1st
