There are a number of techniques to conserve critical lands. The matrix below discusses the most common.

PROS |
CONS |
LAND ACQUISITION |
| Fee Simple Acquisition |
Outright purchase of land |
Most complete means of effecting control and preserving land; compensates landowners completely |
Most expensive approach; managed and maintained by government; takes land off of tax rolls; future administrations may sell land |
| Easement |
Agreement restricting land use in order to protect certain characteristics |
Local governments can initiate purchase of development rights; government has only partial rights and interest in land; income tax deductions for landowners |
Program is affordable only when development pressures are low and consequently prices are low; does not provide for the complete control of land |
| Private Land Trust |
Nonprofit organization which assists landowners & agencies with preservation techniques; purchases and holds conservation easements |
Land is owned and managed by a non-profit organization; tax benefits for landowners; can buy and hold property for future government acquisition; cost savings for government |
Public planning objectives must coincide with private land trust objectives to be realized |
| Purchase and Sellback or Leaseback |
Agency buys land, leases to agricultural users |
Enables government to recover a portion of its acquisition costs; government can exercise direct control over development activity |
Higher burden on government to enforce restrictions; does not necessarily provide for public access |
| Purchase Option |
Allows agency the first opportunity to buy land when it goes up for sale |
Gives government flexibility, security while taking time to make purchase decision |
Cost to government; option may expire before sale of land; "ties up" property; government is responsible for exercising the option |
| Purchase Right of First Refusal |
Government agency has right to purchase first; expires only after agency has had option to purchase |
Gives government flexibility and stability, time to raise funds for a specific project |
Cost to government; "ties up" a property; government is responsible for exercising the option |
| Land Banking |
Purchase and reservation of land for future development |
Can lease for immediate use (e.g. agricultural) to recoup part of cost |
Cost prohibitive |
ADMINISTRATIVE |
| Exactions, Dedications, and Impact Fees |
Fees and mandates placed on developers to pay for infrastructure and amenities |
Removes costs of growth from existing residents |
Complicated to establish; high litigation potential |
| Transfer of Development Rights |
Shifts development from sensitive lands, allows higher density development in "off-site" receiving areas |
Focuses development more appropriately; allows use of existing infrastructure |
It is necessary to have another developable area with a strong demand for growth; substantial administrative commitments to address land valuation and transfer |
| Agricultural Protection Area |
Owners of contiguous land form voluntary association establishing agriculture as primary use of the land |
Protects farmland; relieves farmers from nuisance complaints from surrounding development; landowner-initiated |
Only for agricultural lands; non-binding--landowner can pull out at any time |
| Agricultural Land / Open Space Zoning |
Variety of local zoning laws designed to protect certain land characteristics or specific places |
Zoning tool is readily available to local govts.; reduce conflict between agricultural and residential uses |
Large-lot zoning can promote urban sprawl; can stifle economic growth |
| Quality Development Standards |
Regulations protecting certain natural or visual characteristics of a community |
Community has control over the "look" of development; can target specific aspects to preserve/ highlight |
Can raise property rights issues; overregulation |
| Urban Growth Boundary |
Boundary determined by local government beyond which development is discouraged |
Concentrates development where infrastructure already exists; protects rural character of outlying land |
Can be restrictive; raises property rights issues; can promote "leapfrog" development |
| Performance Zoning |
Developer agrees to meet certain impact requirements, such as leaving a specified amount of land in open space |
Can target either single or multiple impacts; can supplement or replace traditional zoning regulations |
Limits development impacts rather than densities or uses; developers must meet a level of performance |
| Cluster or PUD Zoning |
Allows high-density construction on part of a parcel in exchange for leaving other parts in open space |
Allows for open space; minimizes needed roads and infrastructure; provides flexibility for developers to cluster buildings while maintain-ing overall average density restrictions |
Does not provide for complete control or protection of land |
| Sensitive Lands Overlay |
Superimposes additional layers of regulation upon underlying zoning districts; imposes restrictions on special resources, hazards, or sensitive lands |
Identifies sensitive lands; provides guidelines for development site planning |
Does not provide for complete control or protection of land |
| Building Moratorium |
Local government stops reviewing new building permits for a specified time period |
Gives local officials time to catch up or change policies/visions in times of heavy development pressure; future permits are evaluated with clearer criteria |
State law's 6-month moratorium limit may not be enough time; can hurt local economy; does not decrease the number of building permit applications requiring review |
