PROJECT CONNECT 4 4 of 33B-21CORRIDOR PROGRAM SCALE Corridor Program alone is implementing 50 miles of critical safety and mobility improvements 5 5 of 33B-21CORRIDOR PROGRAM – FOCUSED ON OUTCOMES Corridor Construction Program Map • 10-15% Mode Shift • Average 25% Reduction in Vehicular Delay • 15%+ Reduction in Crashes • Complete Streets/ Complete Communities • 100 bike route connections • 75 miles of sidewalks or shared-use paths • 120 signal improvements • 13 of Austin’s Top Crash Intersections improved 6 6 of 33B-21CORRIDOR PROGRAM - MODE SHIFT The Austin Strategic Mobility Plan’s goal for managing traffic congestion is a 50/50 mode share. This means that we could maintain approximately the same number of cars as we have on the road today, while almost doubling in population by 2039. The Corridor Construction Program will achieve an estimated 10-15% mode shift with a reduction of 4.36 million vehicular trips annually. 7 7 of 33B-21CORRIDOR PROGRAM – CRASH REDUCTION Corridor Construction Program infrastructure is improving safety by an estimated reduction of 200 crashes annually. The Corridor Construction Program is improving 13 of Austin’s Top Crash Intersections across six Council Districts. 8 8 of 33B-21Austin’s average summer temperatures are expected to increase by at least two degrees by 2040. COMPLETE COMMUNITIES INFRASTRUCTURE Corridor Program improvements include rain gardens, landscape buffers, grass, and trees which all help to improve Austin’s quality of life by lessening exposure to heat. • Installing 2000 trees across multiple roadways • Constructing 22+ rain gardens 9 9 of 33B-21CORRIDOR PROGRAM – REDUCED EMISSIONS Transportation produces about 36% of all greenhouse gas emissions in the Austin metro area, with a 178% increase since 1990. “Every transportation decision is a climate decision.” – US Transportation Secretary Pete Buttigieg, SXSW 2022 The Corridor Construction Program is reducing emissions annually along 9 corridors by an estimated 20% or 13,900 tons annually. • Reduced vehicular congestions • Reduced idling at intersections • Multimodal infrastructure and travel choices 10 10 of 33B-21PROJECT CONNECT By expanding transportation options, Project Connect will avert 109 million vehicle miles of travel annually, keeping an estimated 30 tons of NOX and 43,000 tons of CO2 out of Austin’s air every year. 11 11 of 33B-21PUBLIC MOBILITY PROJECTS TYPES OF ROW IMPROVEMENTS • Signal Technology Upgrades Intersection Improvements • • Bicycle and Pedestrian Infrastructure • Pedestrian Hybrid Beacons • Safe Crossings • Multimodal Improvements • Placemaking • Complete Streets • Transit Improvements • Light & Commuter Rail Infrastructure 12 12 of 33B-21CONSTRUCTION IN-PROGRESS 13 13 of 33B-2114 14 of 33B-21PROPOSED CODE AMENDMENTS 15 15 of 33B-21LDC ANALYSIS KEY FINDINGS Current Code does not directly address public mobility projects; treated as commercial development • Department agreements to “translate” code to right-of-way • Variances and waivers from Code and Criteria are common for mobility projects in the ROW • Repeated misinterpretation of Code and Criteria causes (ROW) confusion • Findings cost time and money to resolve LAND DEVELOPMENT CODE 16 16 of 33B-21COLLABORATION Recommendations have been developed through unprecedented interdepartmental collaboration with CPO, ATD, PWD, DSD, WPD, HPD, PCO and more. • Recommendations are consistent with Resolution on Oct. 29, 2021, to create a more efficient and unified framework for all mobility projects.

N. Lamar Blvd. near Kramer Ln. traverses both Urban and Suburban Watersheds with differing Water Quality Impervious Cover requirements • No change to the nature of the roadway • No change to the nature of mobility infrastructure • No visible difference in development intensity • No available land for purchase Urban Suburban 22 22 of 33B-21LDC § 25-8-214 OPTIONAL PAYMENT INSTEAD OF STRUCTURAL CONTROLS Create a Public Mobility Projects Structural Control Fund for payment-in-lieu of built improvements in all watersheds of the City except the Barton Springs Zone. • As funds accumulate, they City can best direct the use of funds for the design and construction of water quality control facilities. Add: (A) The director of the Watershed Protection Department shall identify and prioritize water quality control facilities for the urban, suburban, water supply suburban, and water supply rural watersheds in a [an Urban] Watersheds Structural Control Plan. The Environmental Board shall review the plan in January of each year. (D) The director shall deposit a payment made under Subsection (C) [this section] in the Urban Watersheds Structural Control Fund. (E) A Public Mobility Projects Structural Control Fund is established for use in the design and construction of water quality control facil`ities. (F) For a public mobility project in the right-of-way that is located in an urban, suburban, water supply suburban, or water supply rural watershed, an applicant may request approval to deposit a nonrefundable cash payment with the City instead of providing the water quality controls required under Section 25-8-211 (Water Quality Control Requirement). The payment shall be based on a formula established by the council. The director shall review the request and accept or deny the request based on the standards in the Environmental Criteria Manual. (G) The director shall deposit a payment made under Subsection (F) in the Public Mobility Projects Structural Control Fund. 23 23 of 33B-21LDC § 25-8-262 CRITICAL WATER QUALITY ZONE STREET AND MOBILITY CROSSINGS Clarify that streets, rail lines, and public mobility projects have the same exceptions to develop in all water quality transition zones.
