CITY OF RENTON WASHINGTON

Design

The Surface Water Utility contracted with Otak, Inc. for the delivery of the survey, geotechnical, permitting support, stakeholder engagement, civil engineering design, and construction engineering support services required for this project, through final design. The total contract amount is $1,931,554.30.

Construction

The Surface Water Utility solicited bids from contractors in accordance with City policy 252-02.

At its regular meeting on November 13, 2023, the Renton City Council awarded the construction contract, in the amount of $13,225,647, to KLB Construction.

The target 245-acre subbasin located in the Renton Highlands and President Park neighborhoods does not have an adequate connection to a downstream conveyance system or waterbody. Due to this deficiency and the resulting flooding on Monroe Ave NE, the City entered into an agreement with Segale Properties, LLC for a temporary easement that allowed the City to construct and maintain overflow pipes that discharge to their property at 301 Monroe Ave NE. However, the term of that temporary easement is now ending, signifying the loss of a critical overflow path that has played an essential role in preventing flooding on Monroe Ave NE.

Therefore, it is critical for the City to design and construct a permanent system to replace the loss of the existing overflow pipes. As a permanent solution, the Monroe Ave NE Storm Improvement project proposes to design and construct 2.2 acres of infiltration chambers preceded by an enhanced stormwater quality treatment facility. These facilities will be located on the private property at 301 Monroe Ave NE and will be maintained under a permanent utility easement from the property owner.
