ecological r estoration of the b uilt e nvironment

Ecological Restoration of the Built Environment

The proposal: launch a research and education initiative at the Indiana Dunes National Lakeshore linking the economic, social, and environmental aspects of sustainable building removal to ecological restoration and green space management

Indiana Dunes National Lakeshore

The IDNL: an atypical land use legacy for a national park

A substantial portion of the land is comprised of a patchwork of previous homesites that were demolished and restored to a specific habitat.

When the IDNL was authorized in 1966 there were more than 750 residences within its boundaries.

Many homeowners maintained reservation-of-use until 2010.

Indiana Dunes National Lakeshore

The IDNL: an atypical land use legacy for a national park

Prior to restoration activities buildings are typically demolished, the waste sent to a land fill, and then the land is restored to a prescribed habitat (e.g., wetland, forest, upland dunes, savanna/grassland).

Approximately 60 remaining structures are targeted for removal and habitat restoration.

slide4

The IDNL: an atypical land use legacy for a national park

We estimate that the 600+ structures that have been demolished to date represent 32,400 m3 of landfill waste.

This has an enormous metal and carbon footprint on our regional environment.

significance and critical need

Significance and critical need

The U.S. sends ~136 million tons of building-related construction and demolition waste to landfills each year:

25-30% of all waste produced in the nation

China reports even higher numbers

Minimizing resource use is a key approach to a sustainable economy:

Deconstruction of buildings can reduce construction waste and increase efficiency

Demolition or deconstruction by-product synergies can be made with local construction projects.

Ecological Restoration of the Built Environment

This legacy of the built environment and the IDNL’s mission to restore the land and create park space makes this site an ideal test-bed to explore the concepts and methods of ERBE.

specific goals and intermediate milestones erbe
Specific goals and intermediate milestones: ERBE
  • 1) Create new and link existing courses, seminars, special events, and internship opportunities to develop the theoretical, quantitative, and practical training for cohorts of students in ERBE
    • e.g. Senior Design Teams in DEEE and College of Technology
  • 2) Establish a continuing education program for national park staff and city planners
  • 3) Develop best practice manuals for city planners and national park resource managers engaged in or planning ERBE projects
  • 4) Create an online location- based digital database of invasive species, soil properties, and building details at the study site
    • e.g. Collaboration with Purdue’s visual analytics center (VACCINE)
  • 5) Establish integrated ecological, geochemical and soil science, and microbiological research programs to better understand the success of landscape restoration from the built environment.

Proposed Integration and Coordination ofActivities

Phase One (Initial Site Evaluation) begins with a complete assessment of landscape dimensions and access, building composition and projected reuse/recycle value, an ecological survey of native and invasive vegetation and invertebrate, homesite soil analyses, and interviews with park staff, students, and guests. Local citizen scientist teams will be established during this phase.

slide9

Proposed Integration and Coordination ofActivities

Phase Two (Deconstruction or demolition, Sample Collection, Mapping) will initiate the building deconstruction process, the removal of reusable/valuable ornamental plants and lawn, the establishment of long-term monitoring plots and ecological and soil surveys, the mapping of invasive plants and coordinating their removal.

slide10

Proposed Integration and Coordination ofActivities

Phase three (Restoration, Economic Evaluation, Continued Monitoring) completes the deconstruction and resale/recycle/donation activities, generates detailed economic and life-cycle analysis of building materials, finalizes the infill and grading of the homesite, and initiates the replanting of native species.

Typical Approach

New Approach

Indiana Dunes National Lakeshore

Purdue University

Local Communities and National Stakeholders

New frameworks for collaboration

slide13

AUnique Education and Training Platform: the Current Research Permit

  • ~35 acres
  • Sustainably remove buildings and associated infrastructure
  • Restore the land to the upland forest ecosystem
  • Monitor past 20 years of restoration efforts
slide16

Ecological Restoration of the Built Environment

Linking sustainable building removal to ecological restoration and green space management

Problem: Dormitory and lab space is essential for success of this effort.

Solution: Convert selected sites into high energy-efficiency dormitories and research laboratories (an opportunity forPurdue Alumni Donors?)

slide17

Create jobs in new sectors, e.g., deconstruction, ecosystem restoration

  • Minimize new resource extraction through reuse (asphalt, concrete, wood, metals, etc.)
  • Create integrated sustainable development graduate training programs (international focus)
  • Minimize land fill waste/toxic disposal
  • Create green space for improved environment
  • Create green space that promotes resilience
  • Urban agriculture, urban forests
