1 Los Angeles County Metropolitan Transportation Authority Key Project Elements Status Report presented to the Corridor Advisory Committee August 18, 2016

2 Background Motion 22.1 elements are grouped into four general categories: I. Defines those elements to be included in the technical work scope in the I-710 EIR/EIS process [Technical Work Scope Items] II. III. IV. Identifies elements that Metro and its partner agencies should consider for mitigation during construction, parallel to the I-710 EIR/EIS process Specifies actions Metro and its partner agencies should take, parallel to the I-710 EIR/EIS process Defines a set of bicycle alignments that the technical team is to undertake as a study separate from the I-710 EIR/EIS process 2

Identify as Potential Mitigation III. Additional Studies, Proposals, Policy Criteria II. Develop Detailed Monitoring, Outreach, Safety Plans Specific to I- 710 Construction Plans III. Refinements, Approvals II. Implement Mitigation III. Implement Local/Targeted Hire Policy and PLA IV. IV. IV. IV. Independent Bikeway Projects Studies & Environmental Approval Design Phase Construction Phase Bikeway Projects Open 4

5 I. Technical Work Scope Items Adds the following in the evaluation of Alternatives 5C and 7 within the RDEIR/SDEIS: Right-of-way avoidance designs / evaluation (Alternative 7) Zero Emissions Truck Only Option for Freight Corridor (Alternative 7) Use of best available green construction equipment Maximize drought-resistant greenscape coverage, stormwater best management practices [BMPs] and water quality measures High frequency Express Bus Transit along I-710 Additional transit service analysis Upgrades to the existing LA River Bike Path 5

6 I. Technical Work Scope Items Included in the evaluation of Alternatives 5C and 7 within the RDEIR/SDEIS [Continued] Replacement / enhancement of 28 existing bridges / underpasses to provide access for pedestrians/bikes across the I-710 / LA River Construction of at least five new pedestrian/bike bridges /underpasses [reduce remaining gaps] Complete Streets treatments embedded within freeway design (overcrossings, ramp termini, intersections) Complete Streets treatments for local projects [congested intersections] pursued as part of the I-710 Corridor Project Adding transit service on the bus and rail lines serving the I-710 Project Area Traffic Control Measures [ITS/TSM/TDM] Minimize impacts to LA River 6

7 Zero-Emissions Truck Option (Alternative 7)

8 Technology Neutral Eligible Vehicles Freight Corridor ZE / NZE Trucks Alternative 7 ZE-Only Trucks Alternative 7 (ZE Truck Option) Compressed Natural Gas (CNG) Battery Electric Vehicle (BEV) Range Extended Electric Vehicle with CNG Engine (CNG REEV) Battery Electric Vehicle (BEV) Range Extended Electric Vehicle with Fuel Cell Engine (Fuel Cell REEV) Range Extended Electric Vehicle with Fuel Cell Engine (Fuel Cell REEV) Source: I-710 Project Zero-Emission Truck Commercialization Study (2013) 8

10 Truck Tailpipe Emissions Factors Pollutants of Concern (Heavy-Duty Truck Tailpipe Emissions) Diesel Trucks (in 2035) ZE / NZE Trucks ZE Trucks NO X 0.2 g/bhp-hr 0.02 g/bhp-hr 0.00 g/bhp-hr PM 10 / PM g/bhp-hr 0.01 g/bhp-hr 0.00 g/bhp-hr Major toxics DPM and diesel gaseous toxics NG toxics (gaseous and particulate) 0 DPM: Diesel Particulate Matter NG: Natural Gas 10

11 Approach / Status Estimate Number of ZE Vehicles (Freight Corridor) Estimate Travel: Freight Corridor I-710 / Connecting Freeways Arterial System Emissions Estimates (EMFAC) Dispersion Analysis (AERMOD) Health Risk Analyses (HARP2) Preliminary Findings / Agency Reviews Cost Analysis 11

12 Bicycle / Pedestrian Overcrossings

13 Scope of Study and Approach Baseline Project Features Identify existing and proposed crossings and describe improvements Identify gaps greater than ½ mile between crossings Evaluate and Identify New Crossings Physical feasibility and practicality of freeway and/or river crossings within gaps Consider land uses, bike network and master plans 5 most viable crossing locations Preliminary Design Review locations with City and County public works representatives Establish basic design criteria and applicability to project alternatives Advance plans comparable to baseline features 13

14 Upgrades & Gaps Baseline Project Features 19-mile project divided into 7 sections 5 Sections of I Section of I-405 (crossing I-710) 1 Section of SR-91 (crossing I-710) Crossings: 47 Existing / 29 Upgraded 32 crossing I crossing I crossing SR-91 1 crossing Shoreline Drive 13 gaps greater than ½ mile 14

15 Gaps & Feasible Crossings Section 1: Ocean to I Gaps identified 2 Gaps have feasible crossing locations Section 2: Along I Gap identified 1 Gap has a feasible crossing location Section 3: I-405 to SR-91 3 Gaps identified 3 Gaps have feasible crossing locations Section 4: Along SR-91 No Gaps Section 5: SR-91 to I Gap identified No feasible crossing locations Section 6: I-105 to I-5 4 Gaps identified 1 Gap has feasible crossing location Section 7: I-5 to SR-60 1 Gap identified 1 Gap has a feasible crossing location of 13 gaps have physically feasible crossing locations 1 15
