Ocean Park Boulevard Green Street Project Alternatives & Trade - PowerPoint PPT Presentation

Planning Commission March 4, 2009 Ocean Park Boulevard Green Street Project Alternatives & Trade Offs Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

Purpose of Tonight’s Meeting • Review concept plans and options • Provide input on alternatives and trade-offs Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

CORE CITY PRINCIPLES: Open Space, Green Streets & Pathways, Neighborhood Enhancement, Connectivity, City as Park, & Pedestrian Orientation Project Objectives • Prepare conceptual streetscape alternative designs utilizing community input and green street principles. • Improve walkability and bikeability. • Enhance pedestrian safety. • Implement environmental sustainability. • Provide for beautification and enhanced greenery. • Calm traffic and conflicts at intersections. • Maintain views from the 4th Street overpass. • Address noise and vibrations at bus stops (i.e. 4th Street overpass). • Provide gateways, landmarks, and public art (save the whale mural). Project Objectives Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

COMMUNITY PRIORITY: Reclaim Ocean Park Boulevard as Open Space 126’ – 143’ Typ. 65’ – 75’ Typ. Typical curb widths at the 4 th Street Overpass Comparable Curb Widths in Santa Monica • Santa Monica Blvd. between Lincoln & 26 th – 80’ • Wilshire Blvd. between Lincoln & City limits – 100’ • San Vicente Blvd. between Ocean & 7 th – 130’ Typical Curb to Curb Widths Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

EXISTING PEDESTRIAN CROSSINGS 3 RD Street 4 th Street 1 Main St / Neilson Way 2 3 1 2 3 4 5 Note the lack of marked crosswalks between 6 th Street & Lincoln Boulevard 6 th Street 4 5 Lincoln Boulevard Existing Pedestrian Crossings Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

EXISTING CONDITIONS Single-purpose infrastructure to Narrow sidewalks Conflicts between pedestrians , accommodate cars for former density bicycles , and vehicles Unused / underutilized 20’ right-of-way Potential for green relief Narrow sidewalks at overpass Ocean Park Boulevard Today Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

TREE CANOPIES AND OPEN SPACES Limited tree canopy from 12 year old Cassia trees Austere streetscape Missing trees Pocket parks with no amenities & limited landscaping Existing Conditions Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

COMMUNITY OUTREACH 2 Public Workshops 3/3/08 over 60 participants 4/23/08 over 40 participants 4,000 Invitations • Address walkability and • Presentation of three bikeability alternatives; A, B & C • Enhance pedestrian • Residents • Alternative A – based safety upon OPB Task Force • Business community • Implement environmental approach sustainability • Bicycle and pedestrian • Alternative B – maximize • Provide for beautification advocates and enhanced greenery medians approach • School District • Calm traffic and conflicts • Alternative C – grade- representatives at intersections separated bikeway • Maintain views from the approach 4th Street overpass • Presentation of options - • Address noise and 4th Street viewing deck, vibrations at bus stops traffic circles and bus (4 th Street overpass) stops below overpass • Provide gateways, • Alternative C not pursued landmarks, and public art after input (save the whale mural) Community Outreach Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

PUBLIC HEARING COMMENTS CITY COUNCIL (1.27.09) • ‘Mix and match’ best features from both plans • Re-examine issues addressed by public speakers related to additional crosswalks, bike lane features, and traffic circles. RECREATION AND PARKS COMMISSION (2.19.09) • Maximize opportunities to expand green areas: • Expand community forest and increase tree canopy • Maximize landscaping in center medians • Explore hybrid approach to combing both concepts Public Hearing Comments Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

The Alternatives & Trade Offs Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09

Alternative A • Sidewalk extensions • Landscaped medians east of 5 th St. • New crosswalks • Class II bike lanes • Pedestrian lighting • Vehicular turn constraints • Benches, bike racks, trash • Bus stops relocated to 4 th St. overpass • $3.2M – $4.2M construction cost ALTERNATIVE A: Adapted from the OPB Task Force Consensus Plan Ocean Park Boulevard Streetscape Improvement Project Alternatives Presentation | Planning Commission | 3.04.09
