Service Description:

This GIS dataset contains growth tier maps adopted by local (county and municipal) jurisdictions under SB236. Data are generally collected from county and municipal jurisdictions by the Maryland Department of Planning (Planning) or digitized by Planning in coordination with local jurisdictions. For more information about SB236, see Planning’s Septics Law Implementation Website at https://planning.maryland.gov/Pages/OurWork/SB236Implementation.aspx

This document describes standard operating procedures for aggregating growth tier map GIS data. These procedures may not apply to historical data (i.e. records for which both the SRC_DATE and GIS_SRC fields are blank). For example, Planning may have realigned historical data from local jurisdictions to parcel polygon boundaries or used different procedures to represent municipal tiers when municipalities concurred with county tier maps.

Planning generally requests updated GIS data once a jurisdiction notifies Planning that a growth tier map has been amended. Aggregated data may be outdated or incomplete if Planning has not yet received or processed GIS updates from jurisdictions. Planning generally does not alter geometries received from the local jurisdictions except to divide municipal tiers at the county boundary (see JURSCODE field description). This dataset may contain overlap where multiple jurisdictions designate tiers in the same area.

Fields include:

JURSCODE – MdProperty Viewjurisdiction code (four-letter county or Baltimore City code). For tiers designated by counties, this is the jurisdiction responsible for designating the growth tier. For tiers designated by municipalities, this is the jurisdiction in which the growth tier is physically located. Municipal tiers that cross counties are divided at the county boundary so this field can be populated. See the MUNI field for the municipality responsible for designating a municipal tier.

County – Full name of the jurisdiction represented by the JURSCODE.

MUNI – The name of the municipality responsible for designating the tier. This field will be blank (‘ ‘) if the tier has been designated by a county. The MUNI field is formatted consistently with municipality names in the Planning’s municipal boundary datasets. When municipalities adopt tier maps by concurring with county tiers instead of submitting tier data independently, the MUNI field remains blank within the entire county tier map dataset. Depending on internal needs, an independent municipal tier dataset may or may not be generated by Planning and included within the aggregated tiers.

TIER – Growth tier identifier used by the source jurisdiction and standardized as Tier 1, Tier 1A, Tier 2, Tier 2A, Tier 3, and Tier 4. May include additional alphabetical annotations used by the jurisdictions such as Tier 2B. If the TIER_CODE field is 99, the TIER field retains the descriptor provided by the jurisdiction, which may be a blank or null value.

TIER_CODE – Integer field containing the growth tier standardized by Planning: 1 (Tier I); 11 (Tier IA or any other annotated version of Tier I, such as IB, etc.); 2 (Tier II), 22 (Tier IIA or any other annotated version of Tier II, such as IIB, etc.); 3 (Tier III); 4 (Tier IV); 44 (Areas annotated as Tier IVA for municipal greenbelts or any other annotated version of Tier IV); 99 – Areas included in the jurisdiction’s growth tier GIS data that are not assigned a tier, such as rights-of-way or water.

Adopt_Date – Date growth tier map was adopted or amended. When a local jurisdiction updates its growth tier map, Planning generally requests a comprehensive GIS update to replace all existing data for the jurisdiction.

Acres – GIS acres calculated by Planning in NAD83 Meters (EPSG 26985)

GIS_SRC (GIS Source) – The original source of the GIS spatial and attribute information Planning obtained, which concatenates the JURSCODE field (or MUNI field for municipal tier maps), followed by a space, followed by the name of the shapefile or feature class received from the jurisdiction. Field contains “MDP” if tiers were digitized by Planning, and is blank (‘ ‘) for historical data.

SRC_DATE (GIS Source Date) – The date (YYYYMMDD) the GIS data were obtained by Planning from the local jurisdiction. If the month or day is unknown, the date is YYYY0000. If Planning digitized the growth tier map in coordination with a local jurisdiction, this should be the date Planning’s edits are verified by the jurisdiction. This field will be blank (‘ ’) if Planning’s edits have not been verified or if the dataset is historical and the source is unknown.

NOTE – Text field containing additional notes about the data
