PROJECT NARRATIVE
Project: 4th Dimension Building
Site Location: 4502 NE 4th Street, Renton, WA
APN 1023059068
Site Area: 23,170 SF
The proposed project is to be constructed at 4502 NE 4th Street in Renton. The project will
require a Site Plan Review as well as building permits. The site is zoned CA and all adjacent
parcels are also CA zoned. The existing site has one vacant home which is accessed from NE
4th Street. The site slopes to the north from the rear of the house. The soils consist of ablation
till overlying lodgment till.
The proposed use of the property will be a mixed-use building which will include ground level
commercial uses with residential uses above. The basement level and a portion of the main
level will be parking. Pedestrian access to the project will be from NE 4 th Street and Bremerton
Avenue. Vehicle access will be from Bremerton Ave. Offsite improvements will include
roadway improvements. The estimated cost of the project will be between $8 mil. and $9 mil.
The market value is unknown, but will exceed the costs.
The building is designed to utilize the site topography as much as possible. Estimated quantity
of excavation is 100 cy cut and 4,700 cy fill. There are not significant trees on site. Some trees
within the right of way will be removed in order to widen the road as required. The city has
required a land dedication in order to widen both NE 4th Street and Bremerton Ave. Please see
the site plan for additional information. During the construction phase, a job site trailer is
anticipated. This will be determined in more detail when the project moves nearer construction.
The project is not near any wetland stream, however, there is a drainage pipe which conveys
drainage water from above the property through the site and continues downstream. We
understand the drainage is considered a piped stream. Further, overflow during a 100 year
storm may is currently calculated to use the lowest portion of the site as temporary storage.
The existing 24” diameter drainage pipe is located under the proposed building location.
The proposal includes maintaining the existing drainage way and overflow storage in its current
location and constructing the building above the high water mark. The area below the building
will have access for maintenance and cleanout and pumping access per city specification. The
impact will be to improve the flow of drainage water across the site.
