  • Note = be sure to mention that the study is required by the General Plan Update and prompted by active sales of major landholdingsEach circle animated so Tim can bring them up as he mentions them. Revised order as needed
  • Use this to introduce team members present
  • The plan refers to 4 subareas within the Plan Area
  • Key terms attendees will want to know and understand (4-5 terms)Level of Service (street and intersection, queuing, cycle failure etc.) efficiency of intersection based on how it operates and the number of lanes approaching intersection.Multi-Modal How transportation planning is typically addressed and the kinds of issues dealt with (e.g., how does transportation planner do their work and what are the results?)Key issues, for a project of this type, typically confronted (balancing pedestrian friendly corridor while facilitating auto and bicycle, pleasant walking environment vs. ease of auto movement, readily visible and plentiful parking vs. interesting downtown storefronts, travel patterns changes with major improvements, describe “issues confronted” as complementary not competing, discuss synergy, need to accommodate all modes, everybody is welcome by design)

  • In determining context for walkable urban thoroughfares it helps to understand what a walkable urban place is.Walkable places are urban locations that support walking as an important part of people’s daily travel.There is a complementary relationship between transportation, land use, and the urban design character of the place and because of this walking is enjoyable, and walking, biking and transit are viable and efficient forms of transportation.Walkable places typically have the characteristics listed here.

CENTRAL HEALDSBURG AVENUE PLAN Transportation Planning & Traffic Engineering  What we do  Collaborate with team  Plan mobility and accessibility  Analyze effects of land use  Forecast travel “demand”  Assess travel patterns  Assess streets and intersections  Design multi-modal facilities  Estimate parking needs  Assess safety  Conduct impact analyses
    6. 6. CENTRAL HEALDSBURG AVENUE PLAN Transportation Planning Basics  Terms  Level of Service / Quality of Service Automobile Level of Service User Quality of Service
    7. 7. CENTRAL HEALDSBURG AVENUE PLAN Level & Quality of Service  Level of Service  Letter grades A – F  Based on speed and delays for automobiles  Quality of Service  Letter grades A – F  Based on perception of users

    9. 9. CENTRAL HEALDSBURG AVENUE PLAN Multi-modal Streets
    10. 10. CENTRAL HEALDSBURG AVENUE PLAN Complete Streets Reallocating Street Width to Accommodate All Users 4 lane street narrowed to 2 lanes to add bike lanes
    11. 11. CENTRAL HEALDSBURG AVENUE PLAN What is Connectivity? Connectivity refers to the density of connections in path or road network and the directness of links. As connectivity increases, travel distances decrease and route options increase, allowing more direct travel between destinations.
    12. 12. CENTRAL HEALDSBURG AVENUE PLAN Pedestrian Connectivity  Complete sidewalk grid  ADA accessible  Short blocks  Pathways through parking lots to the doors of buildings
    13. 13. CENTRAL HEALDSBURG AVENUE PLAN Pedestrian Capture Zone  ½ mile walk radius to station
    14. 14. CENTRAL HEALDSBURG AVENUE PLAN Bicycle Connectivity  Complete network of bike paths, lanes and wide shoulders  Connects to regional trail system and SMART station  Signed routes and maps for wayfinding  Short-term and long-term bicycle parking at destinations
    15. 15. CENTRAL HEALDSBURG AVENUE PLAN Bicycle Capture Zone  1½ mile bike radius to station
    16. 16. CENTRAL HEALDSBURG AVENUE PLAN Context Sensitive Solutions (CSS)  Harmony  Balance  Compatibility 16 Photo: Community, Design + Architecture
    17. 17. CENTRAL HEALDSBURG AVENUE PLAN  All users  Compact and mixed-use  Varying densities  Pedestrian-scaled:  Blocks  Buildings / signs  Landscape  Streets  Streets complement uses  Streetscapes with interest and amenity Walkable Places 17 Photo: Kimley-Horn and Associates, Inc.
    18. 18. CENTRAL HEALDSBURG AVENUE PLAN All Streets Can Be Walkable  Different functional emphasis  Serve all users  Different approaches to enhance walkablility Low volume main street High volume arterial
