Shaping our Future Transportation Transportation trends Influencing trends through land use decisions Alternative futures: Base Case and Scenario Complementary transportation decisions
2
Contra Costa has longest commutes in Bay Area: 34 minutes, compared to regional average 28 13% higher than next highest (Solano) Highest growth rate over last 20 years Source: 2000 Census
3
Under trend growth, travel in Contra Costa will grow faster than population : Population growth … 29% Employment growth … 46% Growth in vehicle trips … 40% Growth in miles of travel … 39%
4
Under trend growth, roads will become considerably more congested: 20002020 % of Arterial Miles Congested 21% 34% (Peak hour LOS E or F) % of Freeway Miles Congested 65%90% (Peak hour LOS F in at least 1 direction)
5
Under trend growth, travel will become significantly slower: Increase in congested miles of road … 40% Increase in vehicle hours of travel … 91% Increase in hours spent in congestion … 140%
6
Aside from I-80 Through Traffic is Minimal
7
Almost half of Contra Costa BART rides begin and end in East Bay:
8
Influencing Future Trends through Land Use Decisions (How “6D’s” affect transportation demand)
9
Development Form Compact uses Synergy through mix of use Trip linking opportunities Pedestrian, bicycle oriented Interconnected multimodal streets Walkable destinations
10
Downtown Neighborhood center Infill development projects Large or small-scale activity center Main street Transit station area Urban or suburban neighborhoods Development Location
11
Influencing Future Travel Trends through Land Use Decisions Development Density Diversification of Uses Traditional Neighborhood Design Accessibility to Regional Destinations Distance to Transit Demand Management Policies
12
Higher development densities reduce trip lengths and vehicle travel
13
Scenario increases development density for new growth, both on-average and near transit : Total development density 11% higher for Scenario than for Base Case
14
Diversifying local land uses reduces vehicle trips and lengths
15
Scenario increases local diversification of new growth Development mixing at local level 130% better for Scenario than for Base Case
16
Traditional Neighborhood Design reduces vehicle trips and lengths
17
Travel Reducing Aspects of Design: Dense, Interconnected Street and Sidewalk System Traditional Grid Typical Cul-de-sac
18
Scenario increases amount of TND by new development Scenario has 25% to 30% greater potential for TND than Base Case
19
Dense, diverse, well-designed development is more effective at infill or close-in locations
20
Residents who live and work near transit, ride transit
21
Scenario focuses growth around BART stations and other transit nodes
22
Scenario places more population and employment near transit Under Scenario: 9% of new residents live within ½ mile of transit (compared with 3.5% under Base Case) 12.5% of new jobs are within ½ mile of transit (approximately the same as the Base Case)
23
Projected Differences in Travel Base Case versus Scenario East County West County Central County Lamorinda South Central
24
Change in Person Trips from Base Case
25
Change in Vehicle Trips from Base Case
26
Complementary Transportation Decisions Regional and local modal emphasis and planning guidelines.
27
Programmed Regional Improvements
28
Proposed Regional Improvements
29
Direct next increments of transportation funds toward: Increased Capitol Corridor commuter rail service to Richmond, Hercules/ Rodeo, Martinez eBART through Pittsburg, Antioch, Oakley and Brentwood Express bus on HOV lanes and BART feeder service on I-80 and I-680 north and south. Bus Rapid Transit to Hilltop, Clayton, Oakley Ferry service to Richmond, Hercules/Rodeo, Martinez, Pittsburg/Antioch
30
Recommended Transit Emphasis
31
Recommended Local Emphasis Livable streets.. Context Sensitive Design Multi-modal corridors Balanced LOS standards Speed management Urban Network
32
“It is important that we work proactively with State and local transportation colleagues for designs that preserve the character of this Nation's communities.” (FHWA) Context-Sensitive Corridor Design
33
Context Sensitive Design Goals Change street design from sole emphasis on motor vehicles to: –Multi-modal –Safe and convenient for pedestrians, bikes –Center of community activity rather than barrier Protect adjacent neighborhoods Create economic benefits
34
Context Sensitive Design Objectives Provide balance for all modes Design to encourage driving at the speed limit Improve ability to cross the street
35
Urban Network
