Regional Viewof Arroyo SecoRiver Corridor
Proposed Arroyo Seco Highland Park LA-RIO District: ½ mile corridor on each side of Arroyo Seco Stream
THE GOAL
Provide residents and developers an economic and environmental model for revitalization within Highland Park, appropriate to historical community character and sensitive to resident needs.
PROJECT DESIGN ASSUMES THAT:
The Arroyo Seco Highland Park LA-RIO District will be approved under the LA-RIO Ordinance for Los Angeles River tributaries
Highland Park welcomes revitalization
High potential exists for Transit Oriented Development (TOD)
Watershed management is major focus
Holistic strategies are desired Affordable and innovative revitalization
choices must be attractive to both residents and developers

HOUSING GOALS AND OBJECTIVES
A safe, secure and attractive residential environment for all economic, age and ethnic segments of the community (Northeast Los Angeles Community Plan)
Balance growth with housing Encourage pedestrian activity and
use of public transportation Preserve and enhance the
residential character and scale of existing single and multi-family neighborhoods
LA-RIO ORDINANCE Pending Los Angeles City Council
Approval " LA-RIO is established to implement
the urban design goals and principles established in the Los Angeles River Revitalization Master Plan.... The City's vision for the Los Angeles River and its adjacent Greenway emphasizes a livable, walkable, and sustainable community that is oriented to the River and the surrounding streets. The LA-RIO is intended to support this vision through the enhancement of environmental and urban design.“

Elements
Mobility Program Goals
Provide residents with safe, affordable transportation methods other than automobiles
Connect residents with other parts of the city and allow others to easily access Highland Park with multiple modes and routes
CityBike
Provides residents with bicycle renting and buying options at a low cost through grants and donations
Encourages using bikes as a healthier, zero-emissions alternative to automobiles
Helps participants access jobs and opportunities by providing a means of transportation
Supports and lobbies for items like bike paths and amenities that make biking accessible and more comfortable
Temporary Street Closures
Allows street fairs, regular businesses, and markets to operate regularly while offering a safe, comfortable environment for customers . Avenue 58 is ideal initial location for street closures.
StrØget, Copenhagen Denmark is a “walking street” that offers a great model of how street closures can have multiple benefits

Freedom to move further to the left within travel lane, rather than brave the door zone , squeezed between moving and parked cars, without such markings, bicyclists might seek refuge on the sidewalk or travel in the wrong direction.
Reduce aggressive motorist behaviorencourage correct bicycling behavior
Increase the comfort of (and therefore the number of) bicyclists on shared roads

Special Districts Proposed Cooperative Plans Plan 1: Share information and cultivate sense
of stewardship by fostering cooperative learning centered around community heritage, resource conservation, and wildlife & habitat education.
Audubon Center at Debs Park: vital community resource dedicated to resource conservation and preserving habitat and wildlife.
Arroyo Seco Regional Library: community historians as well as modern information disseminators.
Community groups: Arroyo Seco Foundation, Northeast Trees, and others are valuable mentors and educators.
Arroyo Seco Museum Science Magnet School: teachings emphasize preserving, organizing, and communicating information.
Special Districts Proposed Cooperative Plans
Plan 2: Encourage safe access and pedestrian and bicycle pathways between educational and recreational nodes.
• Coordinate the stated goals of Caltrans and the LA-RIO for enhanced safe mobility
• Monitor safe connections to learning centers• Utilize planned dedicated bike/pedestrian paths• Implement LAUSD’s Office of Environmental
Health and Safety recommendation that students cross at signaled intersections, 4-way stops, and crossing guard stations.
