HUSTON, CITY MANAGER PUBLIC WORKS DEPARTMENT/ENGINEERING DIVISION ACCEPTANCE OF THE PROJECT REPORT AND TO FINAL ENGINEERING FOR THE IRVINE BOULEVARD AVENUE INTERSECTION ENHANCEMENT PROJECT (CIP NO. NO. 10 PROCEED ND NEWPORT SUMMARY The attached resolution will approve the final Project Report for the Intersection Enhancement Project and authorize staffto proceed with Boulevard and Newport Avenue engineering. RECOMMENDATION It is recommended that the City Council adopt Resolution authorizing staff to proceed with final engineering f( Intersection Enhancement Project. approving the final Project Report and the Irvine Boulevard and Newport Avenue FISCAL IMPACT The project is being funded with a combination Funds. and Proposition 111 Gas Tax Funds. budget for this project in the amount of $2. M Competitive Funds. Measure M Tumback uate funds have been budgeted in the FY 1999-2000 CIP BACKGROUND The proposed project consists of Avenue from west of Holt Street to First Street along Proposed improvements inch right and leg turn lanes. ~ of each street in the ran: an attached map (color to the intersection of Irvine Boulevard and Nev,'port to west of Charloma Avenue along Irvine Boulevard, and from Wass )rt Avenue. Refer to the fittached location map. marked exhibit A. widening for an additional through lane in each direction and additional the widening, the existing chrb will be moved back on both sides to 10 feet near the intersection. The specific improvements are depicted on Exhibit B and are described below: · · Newport Avem Improvements: Addition of one through lane in each direction through the Irvine Boulevard int extended separate right turn lane for northbound traffic to eastbound Irvine Boulevard. dual left turn lanes (currently single left turn lanes) at southbound Newport Avenue to eastbound Old Irvine Boulevard. new raised median approaching the intersection in both directions, six new bus stop areas.' landscape medians and parkway landscape where feasible, and associated striping and traffic signal modifications. · Irvine Boulevard Improvements: Addition of one through lane in each direction through the Newport Avenue intersection, separate new right turn lanes for eastbound and westbound traffic to Newport Avenue, dual left turn lanes (currently single left turn lanes) for eastbound and westbound traffic onto Newport Avenue, new sidewalk on the north side from Old Irvine Boulevard to Newport Avenue, new raised median approaching the intersection in both directions, landscape medians and parkway landscape where feasible, and associated striping and traffic signal modifications DISCUSSION The final Project Report describes the right-of-way studies and preliminary engineering analysis in the following areas: Six project alternatives were studied during the project development process. The project alternatives considered various impacts to right of way and the traffic improvement to the intersection. Preliminary. layout plans were prepared which detailed the improvement features. Brief overviews of the alternatives are described below. Alternative 1- Widen Irvine Boulevard and Newport Avenue about the centerlines to full width lanes, bike lanes, shoulders and sidewalks. This alternative has the most impact to right-of-way. Alternative 2- Widen Irvine Boulevard to the south side and Ne~a?ort Avenue to the west side using full width lanes, bike lanes, shoulders and sidewalks. Alternative 3- Widen Irvine Boulevard to the north side Newport Avenue to the west side using full width lanes, bike lanes, shoulders and sidewalks. Alternative 4- Similar to alternative 1, except the centerline of Ir,,ine Boulevard is shifted south to allow for added right turn lanes. Alternative 5- Widen Irvine Boulevard and Nevq~ort Avenue about the centerlines using less than full width lanes, reduced bike lanes, reduced shoulders and reduced sidewalks. By taking these reductions, the right-of-way needs were cut in half. Alternative 6- Similar to alternative 5 with the reduced widths described above, and in addition, single left turn lanes for each direction along NeWport Avenue instead of double left turn lanes in the other alternatives. This further reduces impact to right-of-way. The recommended alternative selected was Alternative 6. This selection was based on being the most cost effective means of increasing traffic capacity and at the intersection while minimizing the need for additional right of way. ~ Traffic studies were completed to demonstrate that the intersection capacity and function would significantly improve from construction of the proposed project improvements. 3. The report identified utilities and storm drains which would be impacted by' the project. . The report examined all of the affected property and estimated the property acquisition needed for the project. The report estimated the proposed project would need right of way from 17 properties. A public scoping meeting was held at which adequate response to. public comments was given. Subsequent meetings were held with some of the affected business owners. As a follow-up in July 1999, over 100 letters were sent to all surrounding property owners and affected agencies notifying them of the current status of the project. As a result, staffhas responded to specific questions from many property ovmers. 5. A Mitigated Negative Decla,. on has been prepared pursuant to ti, alifomia Environmental Quality Act (CEQA). The City Council via a separate resolution has considered this environmental document. The current CIP schedule for this project targets final design phase completion in FY 1999/2000 with acquisition and construction phases being completed in FY 2000/2001. It is recommended that the City Council approve the Project Report and direct staff to proceed with final engineering. A copy of the Project Report is available for revieW at the Office of the City Clerk and at the Public Works Department. Tim D.

The report identified utilities and storm drains which would be impacted by the project. A Mitigated Negative Declaration has been prepared pursuant to the California Environmental Quality Act (CEQA). This environmental document was submitted to the CiD' Council ',;ia separate resolution. NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of Tustin as follows: , That a Project Report has been completed and the report has determined that there are significant traffic and safety benefits to constructing the pr°posed intersection enhancement project.
