What is the subdivision process?
Fact Sheet – The Subdivision and Land Development Ordinance is the most widely-used development control mechanism in Pennsylvania and has been in effect in Mercer County since its adoption by the Mercer County Commissioners December 4, 1958. The Ordinance regulates, as the title suggests, a subdivision and land development within Mercer County excepting subdivisions in those municipalities which have elected to adopt and administer their own local standards of control. The Subdivision and Land Development Ordinance does not control what uses are established within the County or municipality, rather it controls how a use or activity relates to the land upon which it is located.
The subdivision ordinance offers the County and the municipality a degree of protection against unwise, poorly planned development by insuring through the proper provisions of good subdivision design that includes such necessities as properly constructed streets, adequately designed storm water systems, prevention of conflicting deeds and assurance that properties being subdivided and conveyed are acceptable in size, and are properly placed on legal record with the Mercer County Recorder of Deeds.
A “subdivision” is defined as the division or re-division of a lot, tract or parcel of land by any means into two or more lots, tracts, parcels or other divisions of land including changes in existing lot lines for the purpose, whether immediate or future, of lease, partition by the court for distribution to heirs or devisees, transfer of ownership or building or lot development. Provided however, that the subdivision by lease of land for agricultural purposes into parcels of more than ten (10) acres, not involving any new street or easement of access or any residential dwelling shall be exempted.
Land development is defined as (1) The improvement of one lot or two or more contiguous lots, tracts or parcels of land for any purpose involving: (i) a group of two or more residential or non residential buildings, whether proposed initially or cumulatively, or a single non-residential building on a lot or lots regardless of the number of occupants or tenure; or (ii) the division or allocation of land or space, whether initially or cumulatively, between or among two or more existing or prospective occupants by means of, or for the purpose of streets, common areas, leaseholds, condominiums, building groups or other features. (2) A subdivision of land. (3) Development in accordance with Section 503 (I. 1) of the MPC.
