Setting the Stage

The EWN initiative continually seeks opportunities to provide the public with examples of water resources infrastructure that incorporates innovative designs and measures that are consistent with EWN principles. Our team of scientists, engineers and landscape architects have collaboratively pursued novel ways of approaching USACE infrastructure projects that produce the desired engineering outcomes while also achieving substantially greater environmental and social benefits. This page highlights many of the EWN designs that have been identified for a variety of different USACE activities. Through a series of workshops and other engagements, our team has synthesized EWN ideas and strategies into drawings and renderings for a variety of water resources projects. Ultimately, these exhibits were integrated into reports that offer additional details concerning the applicability of the innovative concepts and how they could be assimilated. We invite you to explore this webpage and the associated reports. It is also our hope that the information presented here will inspire you to pursue your own EWN opportunities.

More designs, renderings and reports will be made available as they are completed. We encourage you to visit this page periodically to view the latest design products.

Teamwork and Collaboration

Engineers and scientists that practice EWN are knowledgeable about natural and engineering processes, and they appreciate the “value added” when integrating the two to support a water-based, infrastructure project. Adding landscape architects to our team resulted in another layer of capability, and therefore, expanded the possibilities to identify EWN options for projects. Landscape architects (LAs) are formally trained to think about how people interact with a design. LAs also translate the conceptual stage of a project directly into a specific drawing by using a visual vocabulary for communicating how natural processes can be integrated into traditional engineering projects. Given the complimentary nature of disciplines that are required, and mutual interest in infrastructure enhancement, a collaborative effort was initiated to further promote those shared design principles and precedent knowledge. Thus, EWN strategies are collaboratively pursued by engineers, hydrologists, biologists, ecologists and landscape architects.

The Value of Renderings

Producing LA renderings is a valuable technique that can be leveraged to convey information about a project and its integration with the surrounding environment. Using standard orthographic and perspectival representation techniques including plan, section-elevation, section-perspective, and aerial perspective, LA renderings can depict the intended conditions of a completed project. Various dimensions of a proposed project, such as how it would be experienced by recreational users, how it would provide engineering benefit, and how it might develop as habitat for plant and animal species, can also be illustrated within renderings and described by annotations layered on top of renderings. LA renderings can also be used to make before-and-after comparisons between existing conditions [captured in photographs] and proposed conditions [shown in the renderings]. Such drawings can offer diverse audiences, which include decision-makers, project planners, and the general public, greater insight into future-anticipated changes to environmental conditions and/or the addition of human-use benefits.

Acknowledgements

The EWN initiative is grateful to the Dredge Research Collaborative (DRC) for their collaboration and partnership in the development of the renderings and reports that are showcased on this page. Collaborations between the DRC’s landscape architects and ERDC’s scientists and engineers began in summer 2017. Since that time, the team has pursued numerous projects that have incorporated EWN concepts into traditional water resources infrastructure.

Reports

S2G report cover

S2G Report - This R&D report offers information on the innovative design concepts that were identified for components of the Sabine to Galveston (S2G) Project, which is a project of the Galveston District (SWG), US Army Corps of Engineers (USACE). These design concepts combine Engineering With Nature® (EWN®) and landscape architectural (LA) approaches to infrastructure design in order to identify opportunities to incorporate "Natural and Nature-Based Features" (NNBF) into proposed S2G Project infrastructure.

Comite Canal Project

Comite Canal Project - In fall 2018, the Engineering With Nature® and Landscape Architecture project delivery team (EWN®-LA PDT) began working with New Orleans District (MVN), USACE to develop recommendations for how the on-going design and construction of the canal might incorporate EWN® principles and NNBF. This R&D report offers information on the innovative design concepts that were identified for Comite Canal.

W.P. Franklin & Moore Haven Lock and Dam

W.P. Franklin & Moore Haven Lock and Dam - In fall 2018, the Engineering With Nature® and Landscape Architecture project delivery team (EWN®-LA PDT) began working with Jacksonville District (SAJ), USACE to develop recommendations for how the W.P. Franklin Lock and Dam project area and Moore Haven Lock and Dam project area might incorporate EWN principles and NNBF. This R&D report offers information on the innovative design concepts that were identified for these two project areas.

Back Creek and Fishing Creek Jetties

Back Creek and Fishing Creek Jetties - In fall 2018, the Engineering with Nature® and Landscape Architecture project delivery team (EWN®-LA PDT) began working with the Baltimore District of the US Army Corps of Engineers to develop recommendations for repairing jetties in Chesapeake Beach, Maryland, at the mouth of Fishing Creek; and in Annapolis, Maryland, at the mouth of Back Creek. This study has examined alternative options, which are intended to both maintain the navigation-related performance criteria for the jetties and to provide enhanced ecological value on or in the vicinity of the jetties.
