River Precedents
The Brush Creek Greenway in Kansas City was A
concrete channel like the Los Angeles River
10
River Precedents
The San Antonio RiverWalk Is the heart of the City
11
River Precedents
Denvers Platte River has become green and
accessible
12
River Precedents
The Rio Besos in Barcelona was similar to the LA
River
13
River Precedents
The Choenggye Cheon in Seoul, Korea was
completely re-created

River Strategies

• River Channel

Parks and Open Space
Community Development
22
Greening the Los Angeles River
23
Solutions for Greening

• Increase Capacity

• Widen
• Deepen
• Add Box Culverts and Pipes

• Divert and Store Water Off-Channel to Reduce
  Velocities

24
Factors Affecting our Ability to Green

• Must preserve or expand existing channel flood
  capacity
• Greening will require adding channel capacity
• High velocities can tear out vegetation

25
Vegetation Will Require Adding Channel Capacity
to Maintain Requirements for Flood Storage
To achieve 30 Green in Channel
EXISTING
GRASSES
TREES/SHRUBS
26
More Green Requires More Capacity
27
Increase Channel Capacity
28
Channel Velocity is an Important Factor

River Strategies

• River Channel

Green Veil
Green Terrace
Natural Area Restoration
River Parkway
30
The Green Veil

• anchored above design storm

Existing ROW
31
The Green Terrace

• expands parkland where other opportunities are
  limited
• can be feasible within existing ROW
• 30 green target

32
In-Channel Water Quality Terrace

• opportunities for in channel treatment of medium
  sized storm sewer pipes with high discharge
  (30-48)
• can be feasible within existing ROW

Existing ROW

• 30 green target

33
The River Parkway

• opportunities to reshape channel edge to enhance
  park or parkway experience and access, or to use
  utility corridors (such as area at right)
• located where acquiring additional ROW would be
  feasible

• 30 to 50 green target

Existing ROW
34
Natural Area Restoration

• opportunities for reshaping channel edge or areas
  adjacent to the channel to enhance/restore
  natural systems and habitat, provide for water
  quality treatment, and provide for public use
  where appropriate
• located where acquiring additional ROW would be
  feasible

35
Water Quality Considerations and Possible
Treatment Hierarchy
LOCAL
DISTRICT
REGIONAL

• 30 Pipe

• Individual Sites

• Large Culverts and Tributaries

Drainage Area 17.4 AC
Stormwater Gardens

• Green Strips

• Sand and Wetland Filters

• 48 Pipe

Local River Drainage
Drainage Area 42 AC
Consider water quality treatment in a systemic
manner to maximize efficiency
36
Regional Water Quality Treatment

• Divert dry weather flows from large culverts and
  small tributaries through large areas of wetland
  and other natural filters.

• Workgroup Ground Rules
• 1. There are no dumb questions or bad ideas.
  Speak frankly and freely!
• 2. Listen to others points of view. Please dont
  interrupt, or converse amongst yourselves, while
  others are talking you will have time to
  present your opinions too.
• 3. Allow and encourage everyone to speak do not
  monopolize conversations.
• 4. Keep focused on the agenda and on what you as
  a group will ultimately present.
• 5. The planning team is here to facilitate
  discussion, and to draw and record group
  recommendations. The group will choose a member
  or members to present their plan to the entire
  audience at the conclusion of our exercise.

63

• Ground Rules for Developing Your Plan
• 1. The plan is intended to be a long term vision,
  so do not be held back by potential costs of plan
  features.
• 2. The group may divide the river corridor into
  segments and apply different river strategies to
  each segment, however the group must reach
  consensus on the strategies that are seen as
  most appropriate for each segment.
• 3. The group may choose to keep existing
  conditions as is in some segments. If so, the
  group should describe why this is preferable to
  any change.
