How to implement the plan?




Developing a written plan is an important first step in protecting your community’s open space and natural resources. A good open space plan:

  • formulates protection goals
  • identifies land available for preservation
  • prioritizes available parcels
  • provides implementation strategies, and
  • builds public consensus for land protection.

    A plan sets the stage for future open space financing campaigns, giving voters confidence that their tax dollars will be spent in a rational, publicly-scrutinized manner. Many county and state grant programs require municipalities to adopt open space plans before they are eligible for acquisition dollars. And adopting an open space plan is legally required when municipalities rely on Pennsylvania’s Act 153 to authorize bond issues, property taxes, or earned income taxes for open space purposes. ( See the text of Act 153. )

    This webcast focuses on municipal level plans. Open space plans also can analyze natural resources on:

  • a multi-county basis (Delaware Valley Regional Planning Commission)
  • a countywide basis (Monroe2020) and Chester County Board of Commissioners.
  • watershed or physiographic boundaries rather than political boundaries (See for instance: Schuylkill Watershed Conservation Plan or GIS on QUAKERTOWN , 421K PDF File), and
  • a parcel level, identifying important natural features to be preserved and recommending areas best suited for building envelopes.

    According to professional planners, the most successful plans are written with the following points in mind:

  • the plan needs to take into account your community’s specific needs and interests
  • public participation is important
  • interconnected open space systems should be a goal, and
  • the plan needs to meet the requirements of public funding programs, in order to leverage local dollars.

    Professional planners typically are hired to information-gather and write the document. Consultants typically charge between $15,000 to $25,000 for a municipal open space plan. Adding in traditional park and recreation components (analysis of facilities, programming, etc.) will increase the price significantly.

    The consultant’s work should be supervised by a committee appointed by the township supervisors or commissioners. This committee could be the planning commission, the park and recreation board, or a new committee created for this purpose. Ideally, the municipal Environmental Advisory Council (EAC) will handle the task. EACs are authorized by law to keep inventories of open space, make recommendations for using open lands, and advise elected and appointed officials regarding property acquisition. See Environmental Advisory Council for more information on how to create an EAC. See also Upper Makefield Township Environmental Advisory Council for the various activities an EAC can conduct.

    Although the plan may be prepared by an appointed committee and a consultant, the municipality’s elected officials are the ones responsible for adopting a satisfactory and useful open space plan.

    Geographic Information Systems (GIS) software has become an indispensable tool in creating the maps that are at the heart of an open space plan. Most effective plans now utilize GIS to show different layers of information about a municipality, such as the location of its undeveloped parcels greater than 20 acres, prime agricultural soils, historic resources, steep slopes, forested areas, and wetlands.

    GIS allows you to prepare composite maps that combine multiple natural resource features. These maps show the location of the various landscape features in relation to each other, and can identify critical densities of natural, recreational, and historic features. GIS technology also allows the acreage of individual and multiple parcels to be calculated easily.

    A ranking system provides a basis to explain which properties should be pursued for protection. The protection method may be fee simple acquisition (i.e., outright purchase) or, more commonly, conservation easement (which keeps the land in private ownership but extinguishes agreed-upon development rights).

    The open space law noted above, Act 153, limits a municipality’s acquisition of property interests for open space purposes (as opposed, say, to public recreational purposes) to parcels “designated” for open space uses in an adopted plan. The legislation does not spell out the way that “designation” should be accomplished, but does require municipalities to establish a parcel ranking system.

    Factors typically taken into account in designing an open space ranking system include:

  • whether the property meets one or more plan goals and objectives
  • potential risk of development
  • linkage potential
  • availability of supplemental funding sources, and
  • willingness of landowner to sell easement or fee below fair market price.

    There are a variety of ways that municipalities have set up ranking systems. Some municipal open space plans list or map the tax map numbers of parcels for later ranking by the EAC. Others list the parcels together with their ranking scores, dividing them into levels of priority. Others simply list ranking criteria, leaving parcel identification and actual ranking to a later time.

    See sample municipal ranking criteria:

  • Haycock Twp. Open Space Plan Property Evaluation Form (440K PDF File)

    If, after plan adoption, additional properties are identified and deemed desirable for protection, the open space plan can be amended to incorporate the additional parcels.

    A public hearing will be held to present the plan to the community. Changes can be made if necessary, and the plan will then be adopted by the elected officials.

    Implementation of the action items in the open space plan can be done by the same committee that oversaw its preparation. That committee should sequence and divide up the responsibilities, deciding who will approach and negotiate with which property owner, arrange for appraisals, handle presentations to the governing body, monitor the acquired properties or conservation easements over time, and do the myriad other necessary steps. (See an outline of Bedminster Twp. Land Preservation Program , 260K PDF File)

    Often, a municipality will contract with a local land trust to perform all or some of these tasks. (See pages 20 –21 of Using Conservation Easements to Preserve Open Space: A Guide for Pennsylvania’s Municipalities, for more information on setting up a municipal open space program and working with land trusts.)
