Construction is expected to be completed by the end of October 2018. Construction activities will be restricted to the hours of 7:00 am to 8:00 pm Monday through Friday. Any work on Saturdays will be limited to the house of 9:00 am to 8:00 pm. No work will occur on Sundays. All hauling will be limited to 8:30 am to 3:30 pm Monday through Friday. For this small compact site one construction entrance is proposed. The entrance will be shown on the TESC plan, which will be included in the building permit submittal. Construction traffic is expected to approach site from either Washington State Route 167 or Interstate 405. The map below shows a route to and from the north and one to and from the south; both traveling primarily on major arterials. No truck compression brakes or Jake brakes are to be used. Proposed Construction Transportation Routes to and from Construction Site 2 The construction entrance will be stabilized with 4” to 8” quarry spalls with a depth of 12. If dust from construction traffic is not minimized sufficiently through the use of quarry spalls, a wheel wash will be installed. To minimize other impacts from construction activities standard TESC measures will be implemented such as a temporary construction fence surrounding the property and a silt fence to control erosion. More detail on TESC measures will be included in the building permit submittal. No special hours for construction or hauling are proposed. Much of the proposed construction activity is expected to occur directly on the site and not in the public way. For activities that impact the public right of way, such as the construction of a new sidewalk and connections to utilities, the general contractor will submit a detailed traffic control plan to the City’s Public Works Department. Detailed traffic control plans will be submitted to the City a minimum of three working days before any work in the public way is scheduled to occur. If the work impacts a school bus route, the contractor will notify the Renton School District. Work zone traffic control shall follow the standards of the Manual on Uniform Traffic Control Devices. If a sidewalk is impacted by the work, assistance and accommodation of pedestrian traffic shall be provided.
