benefits spectacular new coastal trail, continuous pedestrian connection enables significant retreat from coastal erosion more flexible infrastructure protection major improvements to sloat blvd design, with green infrastructure elements

constraints some traffic impacts, likely minor requires reconfiguring zoo access cost of roadway and intersection improvementsoutstanding questions nature of traffic impacts? configuration of sloat blvd? funding sources?

KEY MOVE 2 :introduce a multi-purpose

coastal protection /

restoration / access system

2.1 withdraw from bluff edge,

incrementally demolish roadway,parking, restroom at sloat

2.2 reinforce the lake merced tunnel inplace with a low profile structure or

internal ballast, remove revetmentsand fill

2.3 sand nourishment via armycorps,develop and pursue best

practices for beach nourishment

2.4 cobble berm over lm tunnel covered

by sand (via army corps sand

nourishment) serves as wavedissipation zone; overwash occursduring severe storm events

benefits incorporates significant coastal retreat protects costly infrastructure in place for decades a softer approach to coastal protection, that can work with coastal processes restores ecological and recreational function

constraints significant up-front investment from multiple agencies challenging to maintain sand cover and surface restoration depends on careful integration with army corps beach nourishment new approach requiring careful study and monitoringoutstanding questions can the tunnel be protected at a low enough profile for a reasonable cost? how will wave action interact with cobble and sand to shape the beach and

berm?

how will protection measures be phased to prevent spills, protect habitat, andmanage cost?

KEY MOVE 3 :reduce the width of great highway to provide amenities / managed retreat

3.1 reduce great highway from 4 lanes to 2 at balboa-sloat, including wide shoulder for cycling/emergency access; use

current south-bound lanes and median for dune restoration, amenities

3.2 reconfigure great highway/sloat intersection slightly inland, following transport box to avoid erosion

3.3 introduce small pockets of parking distributed at key access nodes

3.4 powered by wind and solarrestore existing restrooms; introduce 3 new off-the-grid restrooms

3.5 improve access at judah, taraval, rivera and noriega with trailheads/info, bike parking, vertical elements, etc

benefits a restored dune system is given space to migrate landward, allowing a

wider beach as sea-level rise sets in. allows space for additional amenities, improved beach access favors pedestrians, bicycles, beach access, and wildlife over traffic flow

constraints traffic impacts, which may be significant, in adjacent neighborhoods limited space gained at substantial cost potential to bring more users to plover habitat areas some redundancy between recreational trailsoutstanding questions what will traffic impacts be and to what degree can they be mitigated? how much additional beach width will result in the long run?

benefits ecological restoration and improved aesthetics removal of non-native species lower profile will allow more visual access to the ocean potential for improved sand management with lower profile

constraints significant cost challenge of fully removing non-native grasses access to dunes limited to protect restorationoutstanding questions would a native dune form offer comparable coastal protection? to what degree would management of windblown sand be improved how can sand placed through beach nourishment best feed the dune

system?
