Not quite designing with nature.
Highly engineered, man-made components of an infrastructure network
Engineering approaching that protects, restores, or mimics natural networks

A system of hubs and links, cores and corridors
Examples include local nature reserves, working lands, regional parks, community parks, and conservation areas
Examples include landscaped pathways, conservation corridors, greenways, greenbelts, and eco-trail systems

Structural Storm Water Management
Objective: Provide adequate stormwater drainage from developed land and attempt to control flood flows. Rise of Gray Infrastructure and "vacate water ASAP"
Water Quality as Storm Water Management
Objective: Adequate drainage, but via management of floodplain development, erosion and sediment control, mitigate point source pollution, and detention facilities
Low-Impact Storm Water Management
Objective: Adequate drainage by onsite mitigation of stormwater flows, infiltration, runoff treatment, protect/restore natural drainage channels with non-erosive velocities
Sustainable Storm Water Management
Objective: Use watershed approach to integrate stormwater management, focus on water quality, stream/habitat restoration, and living community design that amenitizes SWM assets
Mitigate flood damage
Prevent groundwater contamination
Prevent pollution of surface waters
Stream restoration
Habitat protection
Better aesthetics, better design, more livable communities
"An approach to land development that works with nature to manage stormwater as close to its source as possible." - EPA, 2013
Applicable to developing watersheds in urban, suburban, and rural settings.
Alachua County provides a number of examples:

Using LID, improve site design. Cluster development in smaller area of site to preserve native vegetation. Minimize impervious surfaces and prioritize tree canopy.

11.5 acre primarily asphalt and concrete parking area. Runoff retrofits proposed via end-of-island bioretention cells, bioretention swales around perimeter, permeable paving, small storage pond
