Witte Road Improvement Project
SE 249th Place to SE 256th Street
T-28b Phases 1, 2, and 3
Phase 1 – Completed in 2018
Phase 2 – Under Construction (July – November 2020)
Travelers should be prepared for construction related delays on Witte Road. Traffic will be controlled by flaggers through the daily construction work zone. No full road closure of Witte Road will be allowed. A suggested detour of commuter traffic will be designated to use Kent Kangley Road and SR 169 for commuter traffic around the construction. All local traffic will be allowed, with delays.
Phase 3 – Under Design (July – December 2020), Construction (Summer 2021)
Witte Road is considered the City of Maple Valley’s signature street corridor. It is one of only two north to south connector roads in the city and is federally classified as a Major Collector. The Witte Road Improvement Project between SE 249th Place and SE 256th Street (T-28b) has been separated into three phases.
- Phase 1 of the Witte Road Improvement Project was completed in 2018 and included the construction of a fish passage concrete box culvert on the South Jenkins Creek crossing with SE 256th Street at Witte Road and improvements to the alignment of SE 256th Street with Witte Road.
- Phase 2 of the Witte Road Improvement Project includes relocation of overhead power and communications to an underground joint utility trench (Schedule B), relocation of water main conflicts with the future road improvement project (Schedule C), and retrofit of a stormwater pond located at the Lake Wilderness Golf Course (Schedule D). This work is scheduled to start construction in July 2020 and be completed in November 2020.
- Phase 3 of the Witte Road Improvement Project includes road widening to accommodate bikes lanes on both sides, a 6-ft wide sidewalk on the west side only, retaining walls, daylighting of South Jenkins Creek at 220th Avenue SE, construction of a two fish passable concrete box culverts, and construction of a roundabout at Witte Road and SE 254th Place. Construction is anticipated for summer 2021.
On June 22, 2015, the City Council approved the professional services contract with Mead and Hunt to provide the preliminary engineering design of the Witte Road Improvement Project. The project specific goals included 1) a non-motorized multi-purpose facility on one side of Witte Road from SE 249th Place to SE 256th Street and 2) enhance traffic safety by improving the intersections of SE 254th Place and SE 256th Street which included the elimination of the intersection of 220th Avenue SE at Witte Road.
At 90% design, construction costs were estimated to be $4.2M. Grants from the Transportation Improvement Board (TIB) and Puget Sound Regional Council (PSRC) were pursued; however, due to the lack of regional or commercial connection by the project, these grant pursuits were unsuccessful. In 2018, the project was phased using grant funds from the King County Flood Control District, and construction was completed with the realignment of the intersection approach of SE 256th Street with Witte Road and the installation of a fish passage culvert (T-28b Phase 1).
At the April 15, 2019 City Council Study Session, direction was given to staff to pursue design alternatives to reduce the construction costs of the project while still maintaining project specific goals.
At the July 9, 2019 City Council Meeting, the City Council approved Resolution R-19-1330, which increased the professional services contract with PBS Engineering and Environmental, Inc. to redesign the Witte Road project and reduce construction costs.
At the October 28, 2019 City Council Meeting, direction was given to staff through Resolution R-19-1391 to include specific design elements to the T-28b project, including the typical road cross section with bikes lanes and sidewalks, left turn pockets at SE 256th Street and SE 254th Place, retaining walls, closure of 220th Avenue SE at Witte Road with the daylighting of Jenkins Creek, undergrounding of overhead utilities with incorporation of decorative street lights, tree planters throughout the corridor, and construction of new Jenkins Creek culvert under Witte Road just north of SE 250th Place.
At the January 13, 2020 City Council meeting, staff presented the feasibility of a roundabout at the intersection of Witte Road and SE 254th Place, the entrance in to the Golf Course Club House and the entrance to the Cedar Downs neighborhood. Council directed staff to further evaluate the level of service at this intersection by updating the Travel Demand Model with current pipeline projects and land uses.
At the May 11, 2020 City Council meeting, staff presented the City Council with two options to proceed with the Witte Road T-28b project. Council directed staff to separate the project in Phase 2 and Phase 3 as described in the Project Description instead of constructing all improvements and utility relocations in 2020. Separating Phase 3 and preparing for construction in 2021, would give the city the opportunity to apply for any federal infrastructure stimulus funding that may be available in the next year.
At the June 15, 2020 Study Session, staff presented the results of the Travel Demand Model which showed that the level of service predicted in 2035 would be LOS F at the intersection of Witte Road and SE 254th Place without a roundabout. Council directed staff to include a roundabout in the Phase 3 project.
At the June 22, 2020 City Council meeting, Council awarded the T-28b Phase 2 construction contract bid to Pivetta Brothers Construction.
This transportation project T-28b has incorporated the following surface water capital projects into the design and construction:
|S-10||Water Quality Retrofits (existing stormwater pond retrofits)|
|S-16||Witte Road Drainage Improvements (water quality improvements along Witte Road)|
|S-18||Witte Road Culvert Replacements (fish passage culvert under Witte Road just north of SE 250th Place)|
|S-19||254th Jenkins Creek Culvert Replacement (fish passage culvert under SE 254th Place)|
Two public outreach meetings were hosted on July 16, 2019 and November 7, 2019.
