This is Part 3 of our conversation about Hurricane Harvey with the design team at Studio Outside in Dallas, which has won a 2017 ASLA Professional Award for Analysis and Planning for its work on Galveston Island State Park. Part 1 and Part 2 can be found below. Correction appended below on August 28.

Studio Outside’s resiliency plan for Galveston Island State Park earned a 2017 ASLA Professional Award for Analysis and Planning, drawing praise from the jury for its comprehensive and forward-looking anticipation of the havoc a hurricane could release. But Studio Outside’s Andrew Duggan and the design team, led by principal in charge Mike Fraze, knew they were pondering ironclad eventualities, not hypothetical disasters.

Over the weekend, the city of Galveston and Galveston Island State Park to its southwest found themselves in the path of Hurricane Harvey, which made landfall on Friday night, a Category 4 storm that has prompted mass evacuations of the Houston region.

Studio Outside’s project, “Storm + Sand + Sea + Strand: Barrier Island Resiliency Planning for Galveston Island State Park,” tracks the loss of habitat and land as perpetuated by sea-level rise, encroaching development, and hurricane flooding. It prescribes soft and green natural barriers to storm surges, assisted by flexible infrastructure. As a barrier island bordered by Texas’s West Bay to the northwest and the Gulf of Mexico to the southeast, there are few places to hide from floodwaters or to absorb them, and even less given that this part of the island was partially paved over to accommodate RVs in the 1970s. On Friday and over the weekend, Duggan (based safely in Dallas) and members of the design team (Fraze and Duggan of Studio Outside, and Jennifer Dowdell and Ed Morgereth of Biohabitats) emailed LAM some thoughts on how the storm might play out for Galveston Island State Park.

The compensatory mitigation mandate opens a dynamic arena for landscape architects.

From the August 2015 issue of Landscape Architecture Magazine.

 

“Konk-la-ree!”

Or,

“O-ka-lee!”

The song of the red-winged blackbird, although instantly recognizable, is hard to put to words, as even Roger Tory Peterson, author of A Field Guide to the Birds, found. These syllables are his best efforts. The trilling, almost metallic-sounding warble evokes summertime, cattails, and the watery landscapes where Agelaius phoeniceus goes to breed.

But at this moment I’m not seeing cattails. I’m at the edge of a parking lot behind a pizza restaurant in a suburb north of Boston, looking at a large pit, about 10 feet deep, filled with Phragmites australis, the infamous invasive species that, along with purple loosestrife (Lythrum salicaria), is the scourge of wetlands in the Northeast, choking out cattails and other native species that provide food to the bird population. A few spindly red maples have colonized the embankment, along with some riverbank grape (Vitis riparia), Virginia creeper (Parthenocissus quinquefolia), and Rosa multiflora, a pretty though sprawling shrub introduced to America in 1866 to provide rootstock for hybrid roses and now classed as a pest in many states. Despite the red-winged blackbird’s bright song, this is a dismal place, especially in the fading afternoon sunlight, a bit of wasteland left behind by development, one of millions of similar places across the country.

This blighted spot, however, is a mandated compensatory wetland mitigation under (more…)
