Description: <div style="text-align:Left;"><div><div><p style="margin:0;"><span style="font-size:12pt;">This GIS datalayer is a derivation of the </span><a target="_blank" href="https://ftp.granit.unh.edu/resourcelibrary/GRANITresources/standards/ConservationLandsStandard.pdf"><span style="font-size:12pt;"><u>NH Conserved/Public Lands attribute model</u></span></a><span style="font-size:12pt;"> published by NH Granit. In 2014 NRPC began with that statewide dataset and refined the geography of those polygons to coincide with the NRPC parcel dataset. From there, NRPC mapped approximately 400 additional conserved land tracts based upon input from the area's conservation commissions. Using the Hillsborough County Registry of Deeds online database, the NRPC conducted extensive deed research to determine key attributes such as primary protection mechanism(s), managing agency, etc.</span></p><p style="margin:0;">&nbsp;</p><p style="margin:0;"><span style="font-size:12pt;">Relative to parcels, conservation tracts are not 1 for 1. In other words, tracts often cover more than one parcel, some parcels have more than one tract, and non-contiguous areas can be modelled as muti-part polygons.</span></p><p style="margin:0;">&nbsp;</p><p style="margin:0;"><span style="font-size:12pt;">NRPC has added two new protection mechanisms Granit's standard list:</span></p><ul><li><span style="font-size:12pt;"><strong>Town Forests </strong>have a special definition in State Law and must be voted as a town forest at Town meeting</span></li><li><span style="font-size:12pt;"><strong>Set-Aside Open Space Area of Development: </strong>A portion of a development site that is permanently set aside for public or private use</span></li></ul><p style="margin:0;">&nbsp;</p><p style="margin:0;"><span style="font-size:12pt;">NRPC has added the <strong>PROP_TYPE </strong>attribute, which is is NRPC's “plain language” categorization of the land tract, i.e. what is its major defining characteristic or function. Most of these categories are self-explanatory, however the following are the criteria used by NRPC to distinguish between Major Open Space and Parks.</span></p><p style="margin:0;">&nbsp;</p><p><span style="font-size:12pt;"><strong>Major Open Space</strong></span></p><ul><li><span style="font-size:12pt;">Not necessarily town-owned or managed, but if it is, the town considers it a “flagship” or featured property</span></li><li><span style="font-size:12pt;">Exists in a more natural state compared to parks, but is still accessible for hiking and/or other recreation and is considered a destination</span></li><li><span style="font-size:12pt;">Most likely has a notable trail system, which could be a rail trail</span></li><li><span style="font-size:12pt;">Could be a smaller tract adjacent to and/ or tagged with a System Name (e.g. “Joe English Reservation”)</span></li></ul><p style="margin:7 0;">&nbsp;</p><p style="margin:7 0;"><span style="font-size:12pt;"><strong>Parks</strong></span></p><ul><li><span style="font-size:12pt;">In contrast to Major Open Space, Parks are typically characterized by built recreational features (e.g., playground equipment, benches, gazebos) and a more cultivated/manicured landscape</span></li></ul><p style="margin:0;">&nbsp;</p><p style="margin:0;"><span style="font-size:12pt;">NRPC coded the tract as <strong>Other Protected Land</strong> if it does not consider the property to fit neatly into any of the other PROP_TYPE categories.</span></p><p style="margin:0;">&nbsp;</p><p style="margin:0;"><span style="font-size:12pt;">Disclaimer: This dataset is an NRPC interpretation of original source material and maps.
