ACTION: APPROVE PROGRAMMING $1.5 MILLLION FOR NBSSRs
Heading
RECOMMENDATION
Title
PROGRAM $1,500,000 to Caltrans to prepare Noise Barrier Scope Summary Reports (NBSSRs) for three soundwall segments identified as follows: Westbound I-210 from Orcas Ave to Foothill Blvd (Lake View Terrace), Eastbound I-210 from Yarnell St to Roxford St (Sylmar) and Northbound I-405 north of Devonshire St to the I-405/SR-118 connector crossing (North Hills).
Issue
ISSUE
The proposed soundwalls have been deemed eligible for implementation by Caltrans. Caltrans will seek funds under SB-1 for the design, right-of-way and construction of those soundwalls but needs assistance with funds for the NBSSRs.
Discussion
DISCUSSION
Preparation of NBSSRs entails assessment of the feasibility of soundwall projects and defines the project scope by recommending the locations, lengths and heights of soundwalls; identification of the right-of-way needs; and development of cost estimates for proposed projects. Upon completion of NBSSRs, soundwalls meeting all thresholds of eligibility will be designed in accordance with the parameters set in the NBSSR. For the referenced projects, Caltrans will fund the design, right-of-way and construction of the proposed soundwall projects. Metro's contribution toward preparation of the NBSSRs will leverage a larger amount of State funds. The cost of design, potential right-of-way and construction of those projects will be estimated by the NBSSRs.
The I-405 soundwalls are continuation of walls built under Phase 1, Priority 2, Package 5. The eligibility of the proposed extension will be determined by the NBSSR.
