Design Considerations for Retrofitting LID and Green Infrastructure Into
Existing Streets and Neighborhoods
9:30 A.M. – 10:00
A.M.
Presenters: Jennifer Belknap Williamson, Brown and Caldwell,
Portland, OR
Description: Two case studies highlight lessons learned during
LID retrofit feasibility studies and design projects. A retrofit project in
Portland, OR, involved 15 LID vegetated stormwater facilities to collect
stormwater from existing streets in a 100-year-old neighborhood. Issues
addressed included facility sizing; integration into street infrastructure;
traffic, pedestrian, and bicyclist safety and accessibility; protection of
potable water and gas lines; relocation of utility meters; tree protection; and
property owner concerns. The city is now planning a large-scale application of
LID retrofits to reduce CSOs and meet NPDES Phase I requirements, involving 600
retrofit LID facilities over 1,500 acres, drawing on lessons from the smaller
project.
LID for—and Greening of—a Beach Parking Lot
10:00 A.M. – 10:30
A.M.
Presenter: Neal Shapiro, City of Santa Monica, CA
Description: The
city of Santa Monica promotes the use of LID design, and a runoff mitigation
ordinance requires runoff from newly constructed or redeveloped buildings to be
reduced through the use of post-construction BMPs. This presentation describes
the Beach Greening Project, a demonstration project in which a completely
asphalted and impervious beach parking lot was converted into a partial green
multiuse space. Benefits
include recreational uses of the space in addition
to parking, capture and infiltration of stormwater, and reduction of pollution
to the bay.
Indianapolis’s Sustainability Pilot Project: Using Green Solutions to
Reduce Long-Term Control Plan Implementation Costs
10:30 A.M. – 11:00
A.M.
Presenters: Jeremy Kosegi, RW Armstrong and Associates, Indianapolis, IN
and John Hazlett, City of Indianapolis Department of Public Works, Indianapolis,
IN
Description: This presentation outlines a procedure to assess the ability
of sustainable approaches to reduce project costs in combined sewer areas. A
preliminary evaluation considered both partial sewer separation and LID
applications for representative areas in Indianapolis’s Fall Creek basin.
Spatial analysis and hydraulic modeling were used to assess which areas were
suitable for LID techniques, and a hydraulic model was used to quantify the
impact each LID technique had on inflow to the combined sewer system. Effects on
the city’s long-term control plan implementation costs were also assessed.
