Growth by Design, Not by Variance: A Proactive Vision for Chatham’s Rural-Urban Edge
Smart Chatham is fundamentally pro-smart growth. We believe Chatham County does not have to choose between unchecked, auto-centric sprawl and economic stagnation. By grounding land-use policy in proven spatial science, fiscal discipline, and conservation design, we can accommodate regional housing needs while permanently protecting our working farms, mature forests, and watersheds.
The Choice at the Rural-Urban Fringe
When high-growth metropolitan pressures meet rural landscapes, conventional zoning defaults to fragmented subdivisions, clear-cut tree canopies, and overburdened two-lane roads. True smart growth—aligned with Plan Chatham’s "Big Idea" to direct 70% of growth into designated centers—flips the script.
Speculative "Sprawl-by-Variance"
Exploiting ordinance loopholes to claim high residential density while waiving the public benefits required to support it.
- Plan the Gray Before the Green: Clear-cutting 100+ acres of mature hardwood canopy and grading over ephemeral streams to maximize lot yields.
- Disconnected Pods: Fragmented residential cul-de-sacs separated by streams and spray fields that force 100% car dependency for every daily errand.
- Waived Commercial & Buffers: Demanding double density while slashing village commercial space and cutting perimeter roadside viewshed buffers in half.
- Taxpayer Subsidies: Overloading rural schools, bridges, and secondary roads without adequate upfront infrastructure capacity.
Authentic Smart Growth & Conservation Design
Directing market forces into fiscally resilient, environmentally restorative, and human-scaled village centers.
- Plan the Green Before the Gray: Mapping and permanently protecting 40% to 70% of contiguous forests, watersheds, and farmland before drawing a single lot line.
- Walkable Mixed-Use Cores: True village centers where commercial, civic, and diverse housing options sit within a 10-minute walk, capturing local retail dollars.
- Context-Sensitive Rural Edges: Deep, undisturbed 100-to-200-foot native perimeter buffers that honor historic viewsheds and neighboring farms.
- Infrastructure Concurrency: Conditioning development approvals on verified school capacity, municipal wastewater reliability, and multimodal road safety.
Three Regulatory Mechanisms That Protect Rural Character
Leading spatial planners and land-use economists rely on three proven regulatory tools to manage peri-urban transition zones without sacrificing private property rights or economic vitality.
Four-Step Conservation Subdivision Design (CSD)
Instead of laying out streets and lot lines first—which chops forests and wildlife corridors into isolated fragments—Conservation Subdivision Design reverses the engineering sequence. Developers achieve their full baseline housing density on 30%–50% of the tract while permanently preserving 50%–70% as unfragmented open space and agricultural land.
Identify wetlands, floodplains, mature forests, and prime farmland as undivided open space first.
Position building envelopes on non-sensitive soils overlooking the preserved green network.
Draw narrow, low-impact rural streets and connected greenway trails linking every home.
Delineate compact individual lot boundaries as the final step of the site plan.
The Rural-to-Urban Transect & Form-Based Codes
Conventional "Euclidean" zoning regulates only abstract land uses, resulting in monotonous subdivisions and strip malls. Form-Based Codes (FBCs) organize the landscape across a clear continuum—from T1 Natural Watersheds and T2 Working Rural Lands to T3 Sub-Urban Edge Hamlets and T4/T5 Town Centers. By regulating building scale, street connectivity, and public space, FBCs ensure that edge growth forms crisp, walkable villages surrounded by intact countryside.
Urban Service Boundaries (USB), PDR & Transfer of Development Rights (TDR)
To keep working farms and forests contiguous, smart-growth counties pair clear Urban Service Boundaries (limiting where public water, sewer, and high-capacity roads expand) with financial equity tools for rural landowners:
Uses matched local, state, and federal conservation funds to voluntarily purchase conservation easements from farmers—providing landowners immediate capital while keeping the land permanently in agricultural production.
Designates rural farm belts as "Sending Areas" and municipal/transit nodes as "Receiving Areas." Developers buy density credits directly from rural landowners to build in designated town centers, preserving rural land at zero cost to taxpayers.
Where Smart Growth Works: Four National Examples
These communities faced the exact same metropolitan growth pressures confronting Chatham County—and used proactive ordinances to protect their rural heritage while building thriving local economies.
Davidson, North Carolina
Located directly in the path of Charlotte’s rapid expansion, Davidson rejected cookie-cutter sprawl by adopting a landmark Rural Area Plan (RAP), form-based village codes, and an Adequate Public Facilities Ordinance (APFO) that ties development approvals to verified infrastructure capacity.
- Permanently protected over 600+ acres of connected rural open space and greenways.
- Enforces a mandatory 12.5% affordable housing requirement integrated seamlessly into neighborhoods.
- Pioneered low-impact agricultural neighborhoods (like Summit Farms) with dark-sky lighting and rural road cross-sections.
Lexington-Fayette County, Kentucky
Established the nation’s first Urban Services Boundary (USB) paired with a 40-acre minimum lot size in agricultural zones and a bipartisan Purchase of Development Rights (PDR) program.
- Over 28,000+ acres of contiguous farmland permanently protected under conservation easements.
- Leveraged $38.4M in local funds to unlock $41.5M in state and federal matching grants.
- Protected a $2.3B annual agricultural and equine economy while directing infill into the urban core.
Serenbe (Chattahoochee Hills, GA)
A 1,000-acre master-planned community on the rural edge of Atlanta that proves developers can earn higher market returns through conservation design than conventional subdivision sprawl.
- Preserves 70%+ of total land area as permanent forest canopy, stream buffers, and working organic farms.
- Clusters cottages, townhomes, and shops along natural ridge lines to leave valley hydrology untouched.
Orenco Station (Hillsboro, OR)
Demonstrates how a 190-acre suburban edge corridor can absorb high density gracefully by building a genuine walkable town center rather than isolated apartment pods.
- Combines live-work lofts, townhomes, accessory dwelling units (ADUs), and single-family homes around a central village green.
- Connects residents directly to regional transit, reducing household vehicle trips and traffic gridlock.
