The MOA identifies specific costs that will be split 60/40 and anything not covered in the agreement will be the City's expense, for example trenching and backfill. The Committee requested the following additional information: • Cost of trenching and backfill • Cost of schedule delay due to the fish window • Cost to Seattle City Light of pipes over the culvert • Cost to the City of the culvert UNANIMOUS APPROVAL. FORWARD TO AUGUST 7, 2017 REGULAR CONSENT AGENDA. F. Grant Submittal Request: Transportation Improvement Board Staff is seeking Committee approval to apply for a Washington State Transportation Improvement Board grant to fund the West Valley (1-405 to Strander Boulevard) Project. Tukwila applied for this grant for this project last year, and while it was not awarded it was the highest scoring project not selected. The new application will incorporate suggestions from the TIB staff. If awarded, matching funds will be available from federal grant funds, traffic impact fees, and arterial street funds. UNANIMOUS APPROVAL. III. MISCELLANEOUS Staff response to recent public comment The City Council recently heard public comment regarding the safety of the intersection at Tukwila International Boulevard and South 144th St for pedestrians and those with disabilities. Staff responded that a "yield to pedestrian" sign will be installed at eastbound South 1441h Street for those turning right onto Tukwila International Boulevard. This information has been shared with the person who commented. In addition, a resident recently sent the Council a letter expressing concern about pedestrian street crossing times in general. Councilmember Quinn also heard about this at his recent Council Chat at Cascade View Park. Staff responded that pedestrian street crossing times are based upon Manual on Uniform Traffic Control Devices (MUTCD) standards that assume an average walking speed. Certain pedestrian crossing times can be adjusted if there is a demonstrated need at that location. Tukwila has a minimum of 7 seconds at every signal in town. Some people may interpret the flashing signal to be the end of the crossingtime. Extended pedestrian crossing times will also impact vehicle traffic flow, so everything has to be balanced. The City is going to be considering a road diet for Tukwila International Boulevard, and this will create new travel patterns. Councilmember Quinn stressed the importance of data. Chair Kruller asked if extra time could be added at specific times of day, and staff replied that it probably could. Councilmember Duffie noted that crossing times vary widely. There are also new technologies available, such as separate push buttons to request extended time. Staff will follow up with the author of the letterto find out which specific intersection she is concerned about.
