About this Presentation
Introduces conservation subdivision as one option for managing growthSteps before implementationReviews implementation process
Options for Managing Growth
Option 1: Large minimum lot size
Option 2: Purchase of development rights/conservation
Option 3: Conservation subdivision
Assumptions of Conservation Subdivision Process
Growth will continue.
Communities want to protect open space of natural
and historical significance.
Current subdivision process doesn’t adequately
protect open space
Need a process which is fair and equitable to
landowner and developers
What are Conservation Subdivisions?
Creative grouping of new homes onto part of a development parcel so that the remainder is preserved as open spaceProtects important natural, historical, & cultural resources through a community resource inventoryPart of a regional vision: Creates an interconnected network of protected lands. Attempts to balance growth with protection of resources and community identity
Conventional Subdivision
No attention to off-site impacts and viewshedsLittle regard for social aspects of designRigid and traditional application processMinimal design flexibilityTypically strive for maximum density
Why Conservation Subdivisions?
Balances conservation and developmentEquitable to property owners and community membersPreserves rural qualitiesRespects property owner’s right to developConsiders need for new housingAccommodates newcomers without unduly affecting our communitiesMinimizes residential sprawl
Environmental
Protects open space and natural featuresReduces pollutionBuffers sensitive areasProtect wildlife habitat and corridorsHelps maintain biodiversity
Economic
Reduces infrastructure costs. Quality of lifeReduces need for public acquisition of landsCan streamline review process Home valueProperty value remains consistent (Arendt)Helps minimize sprawl
Steps Before the Conservation Subdivision process
I. Evaluate Current Situation2. Develop a Detailed Resource Inventory3. Update Master Plan4. Update Zoning and Site Plan Regulations
1. Evaluate Current Situation
Map land unprotected and undevelopedMap future development under current zoning Review current ordinances and zoning
2. Develop a Detailed Resource Inventory
Identify all natural and cultural resources including
Wetlands and floodplainsSlopesSoilsSignificant wildlife habitatsWoodlands and vegetationFarmlandHistoric, archaeological featuresViewsGroundwater recharge areas
3. Update Master Plan
VisionGoals, Objectives and PoliciesLand UseConservationAdoption by the community
4. Update Zoning and Site Planning Regulations
Options offering a variety of densities and conservation requirementsDensity zoningConservation design
Arendt’s 4 Step Process
1. Identification of critical areas2. Determine and arrange the number of
houses3. Link houses and roads and paths4. Define individual lots and commonly
held land
1. Identification of critical conservation areas including areas that are undevelopable (wetlands, steep slopes)= Development areas
Implementation
What to aim for:– Protected natural
and historic resources
– Subdued entrances
– Neighborhood feel– Interior open space– Protected
