CITY OF COLTON ITEM #10 AGENDA REPORT FOR THE CITY COUNCIL MEETING UY NUVEM1SER 6, ZUU7 TO: HONORABLE MAYOR AND CITY COUNCIL MEMBERS FROM: AMER JAKHER, P.E., PW DIRECTOR / CITY ENGINEER SUBJECT: APPROVE CHANGE ORDER AND AUTHORIZE FILING AND RECORDATION OF THE NOTICE OF COMPLETION FOR THE 10TH AND G STREET TRAFFIC SIGNAL IMPROVEMENT PROJECT. DATE: OCTOBER 29, 2007 BACKGROUND: The Colton -San Bernardino Bikelane Project is a multi jurisdictional project between the cities of Colton and San Bernardino, located within the abandoned Union Pacific Railroad right-of-way adjacent to Colton Avenue. The approximate length of the proposed project is 2.25 miles. The Project starts at Valley Boulevard in Colton moving north along 9t' Street, then eastward on "G" Street connecting to the Union Pacific Railroad corridor on the west side of Colton Avenue, and then extending northeasterly to the City limits and onto Inland Center Drive in the City of San Bernardino. The bikeway travels along Inland Center Drive over the I-215 interchange and continues northeasterly terminating at "G" Street in the City of San Bernardino. Staff applied for and was awarded a $245,000 grant to signalize one of the intersections along the Colton Bike Lane Project, the 10th Street /G Street and Colton Avenue intersection. This intersection existed as a "4 way STOP," where 10'x' Street runs north and south connecting to G Street on the south side only; l0a' Street terminated in the northern direction before it reached the G Street/Colton Avenue intersection. On August 1, 2006, Council amended the city's Capital Improvement Program to include the 10'h and G Street Traffic Signal Improvement Project. It is important to note that this signal project is not a direct part of the Colton Bike Lane Project, but that the proximity of the signal to the Colton Bike Lane Project required the two projects to be coordinated. ANALYSIS/DISCUSSION: The awarded Article III Grant provided funds for installation of a traffic signal at the intersection of 10' Street/ G Street / Colton Avenue. To install this traffic control improvement it was necessary to eliminate a low spot existing at the intersection of F Street and 10' Street. As originally designed, the Engineer's Estimate submitted by Fraco Enterprise for the 10' and G Street Traffic Signal Improvement Project was $604,090. Due to limited funding for this project City staff revised the plan by eliminating the proposed underground storm drain system. To avoid losing the grant funding, City staff formally bid the traffic -signal component of the project and Council action awarded the construction agreement to New West Signal in the amount of $230,304 on May 15,
