CONSERVATION DEVELOPMENT PRACTICES & STRATEGIES
Neosho Community Workshop
Ronda Headland, Community Conservation Planner January 21, 2012
Conservation Development • Maintain Site Integrity
• Soils • Topography • Hydrology • Flora • Fauna
• Built Environment • Site location • Development patterns • Green buildings
• Green Infrastructure • Open Space
• Greenways/connections • Minimize lot sizes/cluster • Recreation/wildlife
Viewing opportunities
• Sense of Place & Cultural Identity

Conservation Development Practices Site Integrity – Hydrology
• Reduce runoff volume (promote infiltration, harvest rain)
• Slow runoff velocity • Filter pollutants from runoff
(suspended solids, heat)

Conservation Development Practices Site Integrity – Hydrology
Conservation Development Practices Low-Impact Development (LID)
• Reduce impervious surfaces • Avoid soil compaction • Surface drainage instead of
underground pipes • Vegetation instead of paving • Roofs – green and blue • Treatment train • Bio-swales • Bio-retention/rain gardens • Native plants • Tree preservation • Green walls • Water quality basins • Street sweepers

Conservation Development Practices Site Integrity – Flora
• Preservation • Native Plants
• Adapted to the climate • Require less irrigation, pesticides, fertilizers • Adapted to pollinators • Wildlife habitat • Reduce mowing/noise pollution • Improve air quality • Rain water management • Carbon sequestration
• Urban Forests • Social benefits • Reduce energy usage for climate control • i-Tree (U.S. Forest Service)

Conservation Development Practices Built Environment – Green Buildings
• Energy Efficiency • Water Efficiency • Indoor Air Quality • Building Materials
• Local sources • Sustainably harvested
and processed • Low-maintenance • Longevity
• Construction Practices • Recycling • Soils • Plants

Conservation Development Practices Green Infrastructure
Green infrastructure is strategically planned and managed networks of natural lands, working landscapes and other open spaces that conserve ecosystem values and functions and provide associated benefits to human populations. www.greeninfrastructure.net
Ecosystem functions that are integrated into the built environment…
