Recommended Action Adopt a Resolution authorizing the appropriation of additional construction contingency on the El Camino Real Road Widening, Median Improvements, Undergrounding Utilities, and Upgrading Traffic Signals, Project Nos. 3957, 3643, 6302 & 6303. Executive Summary On Aug. 26, 2014 the City Council approved Resolution 2014-205 to award a Contract of $8,930,590 with a construction contingency of $1,339,589 to Los Angeles Engineering, Inc. Los Angeles Engineering, Inc. began work on Dec. 4, 2014. The original construction contingency was insufficient given the widely variable existing conditions and the amount of time which had elapsed between initial design and commencement of construction. Discussion The subject project is widening El Camino Real from Tamarack Avenue to Chestnut Avenue. The project will provide three lanes of travel in each direction, bike lanes, a new raised median, curb, gutter and sidewalks, providing operational improvements and enhanced mobility. Additionally, this project will remove the existing utility poles and place the facilities underground as part of the Underground Utility District No. 19, which was formed by City Council on April 27, 2010. Both traffic signals along El Camino Real at the intersections of Tamarack Avenue and Chestnut Avenue will be upgraded. This project obtained easements from adjacent property owners, environmental clearance, and regulatory agency permits to construct these improvements. The project began design in 2005 pursuant to a contract with Berryman & Henigar, Inc. The start of construction was delayed until 2014 because Berryman & Henigar, Inc. was purchased by Bureau Veritas which slowed the completion of the design, as well as staff turnover. During the nine year design period, the asphalt pavement deteriorated prior to the start of construction, discovery of culturally significant artifacts, existence of unidentified subgrade deficiencies, as well as a multitude of design issues that required changes to nearly every element of the project. Project contingencies, by nature, are intended to facilitate the real-time mitigation of constructability issues typical of roadway construction via minor revision, adjustment, and Item #3 September 27, 2016 Page 1 of 13 modification of project plans, and are inadequate to support the design revisions determined to be necessary during the execution of this project. Drought requirements initiated a necessary change to the landscaping irrigation originally designed for the project. City staff completed the design and received a proposal from Los Angeles Engineering, Inc. to install the recycled water line as a change order to their existing contract. On Jan. 12, 2016 City Council authorized a Change Order and additional contingency of $447,529 for the installation of the recycled water line by Resolution No. 2016-010. Culturally sensitive material was encountered during the initial grading and excavation of the project. Staff worked in conjunction with the designated Most Likely Descendent, represented by Saving Sacred Sites, to assess and determine the necessary efforts consistent with Council Policy 83 (Tribal Cultural Resource Protection). Staff prepared a Request for Proposals outlining the scope of work necessary for the archeological recovery and processing of material. A Professional Services Agreement was awarded to Atkins North America, Inc. and additional funds were appropriated in the amount of $662,633 by City Council via Resolution 2016-054. The culturally sensitive material encountered during exploratory excavation of the project caused several delays to the progress of the project. Additional excavation and sorting of the material was required prior to completing the necessary improvements. The project impacts have not been fully realized because there are several more weeks of processing material that need to be completed. Unacceptable subsurface conditions were encountered during construction of the drainage systems along the eastern boundary of the project. The unsuitable material had to be removed and disposed of causing increased construction costs and schedule impacts. Undocumented fill containing large amounts of debris were encountered during the grading operations of the slope in the northeast portion of the project. Geotechnical reports identified debris up to 15 feet in depth. However, debris was encountered more than 30 feet in depth. The discovery of the additional debris caused increases in cost and construction time. Traffic had to be diverted onto the existing paved median area in order to construct the eastern half of the roadway. The existing paved median immediately failed under traffic because it was not originally constructed to withhold a traffic load. The contractor was required to perform emergency repairs in order to maintain traffic. The repairs caused increases to cost and construction time. Additional appropriations are required to perform additional roadway subgrade analysis, and perform additional work to construct the roadway to be stable enough to perform under heavy traffic loads for the anticipated life expectancy. Due to the number and extent of unforeseen changes to the project there have been large expenditures to the construction contingency and extended the schedule of the project. Therefore, staff is requesting additional construction contingency to complete the project. Item #3 September 27, 2016 Page 2 of 13 Fiscal Analysis This project is funded with Traffic Impact Fees, TransNet funds, Public Facilities Fee funds and Infrastructure Replacement funds. The project budget and current expenditures and encumbrances are shown in the table below. An additional appropriation of $600,000 is being requested from the Traffic Impact Fees at this time to fund the required increase of construction contingency. Funds are available in the Traffic Impact Fees to support this request.

Environmental Evaluation (CEQA) A Mitigated Negative Declaration (MND) and Mitigation Monitoring and Reporting Program were prepared for the El Camino Real Road Widening project (CDP 07-22 / HDP 07-02 / SUP 07-04 / HMP 07-08) and this project is within the scope of the MND. The Notice of Intent to adopt an MND was published in the newspaper Nov. 1, 2007, and sent to the County Clerk's Office for a 30-day public period. The MND was adopted by the Planning Commission on June 3, 2009 in compliance with the California Environmental Quality Act (CEQA) Guidelines Section 15074. Item #3 September 27, 2016 Page 3 of 13 Climate Action Plan Consistency This project/action is a continuation of a project/action started prior to CAP adoption in September 2015. However, several features of this project will help decrease GHG emissions such as improved traffic flow and congestion relief, as well as installation of new LED lights. The project will also increase water quality with the installation of several storm water treatment structures. Public Notification None Required. Exhibits 1.
