The zoning boundaries map layer is an integral part of the planning data in the City of Worcester Geographic Information System. This data is used by many City Departments in case review, code enforcement, and long range planning. Planning data layers are accessed by personnel in most City departments for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on planning analysis, spatial analysis, presentation output, and review of proposed development. The zoning boundaries data layer is governed by ordinance and is only changed accordingly. The zoning data layer was digitized by L. Robert Kimball & Associates, Inc. as part of a data conversion project in 1995. Further updates have been made by the City of Worcester since that time to reflect ordinance changes.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity, and were defined by local participants as part of the 2020 Census Participant Statistical Areas Program. The Census Bureau delineated the census tracts in situations where no local participant existed or where all the potential participants declined to participate. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Physical changes in street patterns caused by highway construction, new development, and so forth, may require boundary revisions. In addition, census tracts occasionally are split due to population growth, or combined as a result of substantial population decline. Census tract boundaries generally follow visible and identifiable features. They may follow legal boundaries such as minor civil division (MCD) or incorporated place boundaries in some States and situations to allow for census tract-to-governmental unit relationships where the governmental boundaries tend to remain unchanged between censuses. State and county boundaries always are census tract boundaries in the standard census geographic hierarchy. In a few rare instances, a census tract may consist of noncontiguous areas. These noncontiguous areas may occur where the census tracts are coextensive with all or parts of legal entities that are themselves noncontiguous. For the 2010 Census and beyond, the census tract code range of 9400 through 9499 was enforced for census tracts that include a majority American Indian population according to Census 2000 data and/or their area was primarily covered by federally recognized American Indian reservations and/or off-reservation trust lands; the code range 9800 through 9899 was enforced for those census tracts that contained little or no population and represented a relatively large special land use area such as a National Park, military installation, or a business/industrial park; and the code range 9900 through 9998 was enforced for those census tracts that contained only water area, no land area.Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost.

The City's Zoning Ordinance and Map are tools for land-use planning. Each zone and overlay classification guides the physical development of the City through a set of requirements set forth in the City of Worcester's Zoning Ordinance as amended. As part of the planning data layers, the zoning overlay districts map layer is an integral part of the City of Worcester Geographic Information System. Planning data layers are accessed by personnel in most City departments for basic applications such as viewing, querying, and map output production. More advanced user applications may focus on planning analysis, spatial analysis, presentation output, and review of proposed development. This feature class combines the previously separate Mixed Use Districts and Overlay Districts, with the addition of Local Historic Districts.This map data layer represents the zoning overlay districts for the City of Worcester, Massachusetts as defined by the Zoning Ordinance, Article III, as amended.OVERLAY DISTRICTS: MU: Mixed Use Development FP: Floodplain AE: Airport Environs WR: Water Resources Protection AOD: Arts Overlay District AROD: Adaptive Re-use Overlay District SPOD: Shrewsbury Street Parking Overlay District BCPOD :Blackstone Canal Parking Overlay District CPOD: Chandler Street Parking Overlay District GPOD: Grafton Street Parking Overlay District QPOD: Quinsigamond Village Parking Overlay District DSOD: Downtown/Blackstone Canal Sign Overlay District BSOD: Blackstone River Parkway Sign Overlay District USOD: Union Station View Corridor Sign Overlay District Informing Worcester is the City of Worcester's open data portal where interested parties can obtain public information at no cost

The FIRM Database is the digital, geospatial version of the flood hazard information (location and attributes for boundaries of flood insurance risk zones) shown on the published paper Flood Insurance Rate Maps (FIRMs). The FIRM Database depicts flood risk information and supporting data used to develop the risk data. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual-chance flood event, and areas of minimal flood risk. The FIRM Database is derived from Flood Insurance Studies (FISs), previously published FIRMs, flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by FEMA. The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities located or to be located in identified areas having special flood hazards, " Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP. The FIRM Database presents the flood risk information depicted on the FIRM in a digital format suitable for use in electronic mapping applications. The FIRM Database serves to archive the information collected during the Flood Risk Project. This dataset shows flood hazard data from the 2011 FIRM. This data has been superseded by the FIRM effective 7/8/2025.For more information about the FIRM and flood hazards in the city, visit the City of Worcester website. The latest digital FIRM data is available from the FEMA Map Service Center and can be viewed in the Worcester Atlas map viewer.
