~l~nment A As shown on the attached, Alignment A provides for a gentle sweeping alignment that, from an engineering standpoint, is preferred. This alignment provides for a greater capacity due to increased design speeds. In addition, the bridge alignment is a simpler design and the bridge location allows for the possible future construction of a light rail system along the existing railroad alignment. As with Alignment B, the removal of the railroad allows the construction to occur along existing grades and excessive filling/raising of the roadway is not required. The negative aspects of this alignment focus primarily on the proximity to the residents on Lingate Court and Lingate Creek. The residents are concerned 'that the construction of the roadway within approximately 80 ft. of two homes will create an intolerable situation and decrease their property values. One other aspect is that a small portion of the park strip between the existing railroad right-of-way and Lingate Street will be used for the roadway right-of-way for Alignment A. A!i~nment B As shown, Alignment B tightens the curves along the alignment. While still acceptable from an engineering standpoint, the design speed of the roadway will. be decreased. The bridge design, due to the angle across the Arroyo Mocho and the sharp curves, becomes more difficult to design and more expensive to construct. In addition., this bridge location necessitates removing the railroad trestle prior to construction as well as the relocation of S.P. pipeline's 16 in. high pressure oil line. In addition, this align~nent, while not precluding a light rail system, makes locating a satisfactory alignment more difficult. Hcwever, this alignment more evenly splits the distance between all residents in the area, maximizing the distance for each homeowner and thereby reducing the impact to all residents. In addition, with the proper locating of the soundwalls, the usability and enjoyment of the existing park strip will increase. This project has been budgeted within NPID 82-4. An agreement will be worked out with Prudential for the reimbursement to the Distric't of all costs associated with the design and construction of this project within Hacienda Business Park. The remainder of the project wi!] be at District expense. With this in mind, a contract with Bisseil and Earn, Inc. has been prepared for your review and approval. The contract provides for this project to be under construction by the late summer 1986 with all work within the Arroyo Mocho completed by October 15, 1986 in order to meet Zone 7's requirements. Should any portion of the approvals or design be delayed, work on the bridge may be delayed until April 1987 to comply with Zone 7's requirements with regard to working within the Arroyo Mocho.
