Planned Unit Development Overlay
Aquifer Recharge Protection Overlay	Not large impact on buildability: .Acceptable Range: 9 - 1.0
Farmland Conservation Overlay	Not large impact on buildability: .Acceptable Range: 9 - 1.0
Infill Zones	Temporary Placeholder
Flood Prone Conservancy	Although an overlay, not included in this list.  Constitutes absolute constraint in entirely of area.
