1.0 LA CES-HSW CEH
The course describes the restoration of the Hendrix Creek Preserve (HCP). The site created an 18-acre multi-functional environment in the form of a conservation easement. The primary purpose of the HCP is to provide stormwater management to prevent flooding within a 500-acre watershed area in the City of Conway. Through selecting plantings and controlled stream flows, water leaves the environment cleaner than when it enters. The Watershed also collects and retains storm events to recharge ground water. In addition, the HCP redirects and improves a pre-existing overburdened stream to create a natural public recreation area that is a cornerstone to The Village at Hendrix’s sustainable community development. Southwestern Energy also benefits from the HCP as it teaches their employees the value of ecological restoration and how the environment can be affected in a positive way. The series of trails and boardwalks that wind through the HCP provide a tranquil place for public recreation. The constructed wetlands in the watershed promote habitat for aquatic life, migratory birds and waterfowl. Additionally, the improved habitat functions as an outdoor classroom to encourage the study of the natural systems inherent in the HCP. The HCP was a collaborative project involving the landscape architect with the leadership of The Village at Hendrix, Southwestern Energy, environmental studies and biology faculty, environmental engineers, and the US Army Corps of Engineers. The landscape architect lead a design team that included stream and wetland delineation and mitigation reports, Corps 404 permitting, HEC-RAS modeling, traffic engineering and structural engineering. The landscape architect was responsible for construction documents, bidding and negotiation, construction administration and project inspections.
The HCP creates a natural environmental machine that handles with rainwater collection, cleansing, purification and distribution. The Army Corps of Engineers is the representative of the governmental body to which is held accountable, permitted only native trees, shrubs, and herbaceous species that are currently adapting to the existing climate and micro-climate. These plant species were purchased with the same geographic region that they were planted. Additionally, turtles and fish now inhabit the creek, and the new wetlands serve as migratory resting points for waterfowl.

1.25 LA CES-HSW CEH
Heifer International Martin L. Smith, PLA, EDG
The course describes the site design for the Heifer International World Headquarters. This site could not be initiated without consideration of Heifer’s unqualified commitment to sustainability, conservation and education. The site design of the campus speaks their issues and demonstrates their reality through the following objectives: Integration of conservation and educational elements, reclamation of an industrial brownfield, leadership in energy and environmental design, constructed wetland the serves global-education, as well as being practical, environmental purposes, and a sustainable parking field that will positively impact the Arkansas River watershed.
The site design is conceived as a series of concentric rings that expand out from a central commons, much like a drop ripples water or passing of the gift creates ever-expanding circles of hope in a village. One of these rings consists of a constructed wetland which creates and educational conservation experience with a global context. The wetland promotes biodiversity in a natural ecosystem. This is aided by planting of indigenous plant material to wetland in Arkansas in a unified structured form reflective to the architecture. The intent is to draw native Arkansas wildlife back to the former industrial site while providing an educational campus for the surrounding urban environment and retreat for the employees of the campus. The site design and structured landscape forms represent the diversity and necessity of human communities, as well as good ecology. With the first rule of ecology in mind “everything is connected to everything else” the parking field serves as an environmentally protective storm water filter and harvesting system. Like the wetland, the open-space bio-swales support native grasses, forbs and wildflowers. The bio-swales offer food and shelter to the native wildlife. Because everything is environmentally connected to everything, the effects will multiply as they ripple through the watershed.
From start to finish the Heifer International site presented many challenges which were transferred into unique opportunities. The existing site was an industrial Brownfield with 95% pervious surface. The solid materials such as concrete were crushed and used as base material for the parking field. Brick pavement was recycled and used as entry paving and sidewalks. The heavy clay soils dug out of the basin area were utilized to line the constructed wetland around the office building, therefore eliminating the need to haul this material off site. The project construction was completed in 2004 as the public truly first Platinum LEED project certified in the State of Arkansas and has had its 10th year anniversary recently. The public truly sees the global ripple landscape architects have the ability to create.
Dan Beranek, P.E. LEED AP, President Little Rock, McClelland Consulting Engineers, Inc., the Civil Engineering Firm on the project, and Cinde Bauer Drilling, PLA, Landscape Architecture, Inc., will lead a joint discussion on the value of collaboration between Civil Engineers and Landscape Architects on the Clinton Presidential Library.
In addition, Ms. Drilling will review particularly the Integration of Planting Design with Site Design: A discussion of the development of the planting design for the William J. Clinton Presidential Center & Park. Participants will: Understand the process for developing the planting design within the context of the overall project; Understand the design goals for integrating the planting design within the site design; and Comprehend the reasons for selections of specific plant materials.
Little Rock Creative Corridor Steve Luoni, Director, University of Arkansas Community Design Center
The Creative Corridor retrofits a four-block segment of a neglected historic Main Street in downtown Little Rock, a small city with 200,000 residents. The proposal is based on place-based economic development driven by the introduction of an arts economy rather than resuscitation of the street’s traditional retail base that decamped to the suburbs fifty years ago. The project approach is premised on the role of the street in capturing value through townscaping strategies that feature low impact development landscapes, architectural frontages, public art, signage, and shared street geometries. Working with the mayor as the client was especially helpful since most of the recommendations in thei Complete Street proposal were non-conforming with current municipal codes.
The presentation will address four general insights gained from working with the mayor. First, streets are political projects more than they are technical projects. Second, the mayor’s office is the only resource capable of organizing otherwise fractured interests. Third, only a mayor can mobilize the public works department to rethink its practices in the commissioning and administration of street projects. And fourth, despite seemingly strong executive personalities, mayors need positive feedback as to what they are doing right and why.
All presentations have been registered and will be recorded through the Landscape Architecture Continuing Education System. Professional Development Hour (PDH) is the term that LA CES uses to measure how much credit a course carries. Arkansas jurisdiction uses Continuing Education Hour (CEH) to identify instruction for continuing education. PDH hours = CEH hours. Health Safety and Welfare (HSW) applies to those courses meeting HSW requirements. See https://laces.asla.org for definitions of HSW and calculations used for continuing education hours.
