Rain Garden Installation for Peggy W. Edmiston Administration Building (2015)

On June 20, 2015, the Shelby County Engineering program in partnership with Memphis-Shelby County Office of Sustainability with support from Tennessee Chapter of the American Society of Landscape Architects (TNASLA) installed four green infrastructure demonstration rain gardens at the Peggy W. Edmiston Administration Building (one of the largest Shelby County Government offices) and will offer multiple educational sessions to homeowners in the fall.  A TDEC Green Development Grant was received for $20,000 for this project.  See video of the rain garden as it was installed here and press release here.   Article here.  

Rain Garden Installation for Three Shelby County School Buildings (2015)

City of Memphis Engineering program in partnership with Memphis-Shelby County Office of Sustainability installed three green infrastructure demonstration rain gardens, one each, at Belle Forest Community School, Hickory Ridge Middle, and Kirby High.  In addition to these installations done by Michael Hatcher & Associates and True Green, lesson plans developed by Clean Memphis, were designed for these schools to incorporate rain gardens into the curriculum.  TDEC Green Development Grant was received for $25,180 for this project that was completed in June 2015.   https://news.tn.gov/node/9971 

 

Memphis-Shelby County Low Impact Development Competition (2014)

Memphis-Shelby County Office of Sustainability launched the Low Impact Development Design Competition in April 2014 with completion in September 2014.  This was an opportunity for design firms to showcase their skills with Low Impact Development and the winning teams received $21,000 in awards. 

Low Impact Development (LID) is a way to treat stormwater runoff in a way that mimics the natural hydrology of the site instead of the traditional method of piping the water directly off the site.  The impetus for this competition is the updated regulations that will affect all municipalities as their stormwater permit gets renewed over the next few years. 

A competition is an innovative way to encourage professionals to use Low Impact Development (LID) as a way to treat stormwater on site through natural infiltration.  In 2010, the first LID design competition was launched in Houston, Texas on flat, clay land.  Over the past few years other cities have followed their lead.  Houston’s competition entries showed a 5%-30% reduction in development costs and by 2011 the area saw more than 100 LID-based projects submitted for development up from zero the previous year.  Firms that participated in the competition then became the leaders in the new LID marketplace, changing their previous way of doing business.  Today they continue to foster a long-term collaborative relationship with other team members.  If this same result can be extrapolated to the Memphis-Shelby County area, the movement will also trend toward LID designs.

Background & Funding:

Memphis-Shelby County Office of Sustainability received a $21,900 Green Development Grant from Tennessee Department of Environment and Conservation (TDEC) and their partners Tennessee Stormwater Association (TNSA), Tennessee Valley Authority (TVA) and Tennessee Department of Transportation (TDOT).  With this funding, the office hosted a two-day conference on Low Impact Development (LID), March 6-7, 2014.  Over 100 design professionals in the fields of engineering, landscape architecture, planning, architecture, development, and others attended.  It was a free conference and open to the public.  Presentations from the March 2014 conference can be viewed here:  http://www.sustainableshelby.com/LIDworkshop

The Design Challenge:

The 12.5 acre competition project site is located near the intersection of McLean Blvd. and James Road in Frayser.  It is within United Housing Inc.’s Wolf River Bluffs Planned Development, north of the existing single family units.  Design teams consisted of at least one licensed engineer and one licensed landscape architect, with a minimum of one being local.  Other team members could be architects, planners, developers, construction and homebuilding disciplines, and students.  Using LID techniques for stormwater design, teams submited a site layout of the property for senior living townhomes and a small building for community gathering. 

“United Housing is really excited to be a part of the LID Design Competition,” said Tim Bolding, Executive Director of United Housing.  “Green, sustainable development is the goal for Wolf River Bluffs and this project fits in perfectly by creating quality living spaces, managing stormwater in an environmentally sensitive manner, and meeting a real need for older adults in Shelby County.” 

Round 1 & 2 Judging:

Eleven teams representing 28 firms submitted their designs (each is a link below to their round one submitted design).  The Memphis-Shelby County Office of Sustainability is grateful to all teams for participating in this competition.  By participating, the teams are all helping to advance the practice of Low Impact Development in the region.  At the bottom are the three documents the teams used for this competition: Registration Form, Rules, and Design Challenge Site (containing links to all site documents).  Participating teams included: 

Round one judging was conducted by expert professionals in Low Impact Development that are members of the Houston Land/Water Sustainability Forum.  The top teams received 80% of their score by these judges moved on to the final round of judging for their remaining 20%.  Memphis-Shelby County Office of Sustainability announced on August 11, 2014 the three teams who moved to the second round of judging. In the final round, a local jury of 17 civic leaders, design professionals, developers, and other decision makers judged the teams on their project and overall presentation during a live event.  Final awards event (round two of judging) took place Sept 4, 2014 at the Dixon Gallery & Gardens to a crowd over over 100.  Introductory presentation by Christine Donhardt can be viewed here.  Presentations of the finalists are below (the second round submission):
