The City’s certification programs, including the Minority and Women-owned Business Enterprise (M/WBE) Program, the Emerging Business Enterprise (EBE) Program and the Locally-based Business Enterprise (LBE) Program certify, promote, and foster the growth of the City’s minority and women-owned businesses and eligible small construction and construction-related businesses. Companies that become certified obtain greater access to and information about contracting opportunities, receive technical assistance to better compete for those opportunities, and benefit from inclusion in the City’s Online Directory of Certified Firms. This list contains detailed information on certified companies, including a brief description of their work history, contact information, and detailed information about what the companies sell. This data is up to date as of the date reflected in the "About" tab of this dataset.

Larger NYC parks (generally >20 acres) are subdivided into smaller sections that make inspecting these parks feasible and efficient.  These sections are called "zones."   The size and boundaries usually conform to one or more of the following criteria:  Zones should be inspectable in 1-2 hours; zone boundaries should follow the park’s features (paths, tree lines, etc) whenever possible; and/or conform to pre-existing boundaries used to divide the park for maintenance; and/or define a cohesive area within the park (ballfields, wooded areas, etc).  Besides zones, this layer contains a handful of Sitting Areas that are part of larger parks but could not be defined as zones due to their smaller size.

NYC 1foot Digital Elevation Model:
A bare-earth, hydro-flattened, digital-elevation surface model derived from 2010 Light Detection and Ranging (LiDAR) data. Surface models are raster representations derived by interpolating the LiDAR point data to produce a seamless gridded elevation data set. A Digital Elevation Model (DEM) is a surface model generated from the LiDAR returns that correspond to the ground with all buildings, trees and other above ground features removed. The cell values represent the elevation of the ground relative to sea level. The DEM was generated by interpolating the LiDAR ground points to create a 1 foot resolution seamless surface. Cell values correspond to the ground elevation value (feet) above sea level. A proprietary approach to surface model generation was developed that reduced spurious elevation values in areas where there were no LiDAR returns, primarily beneath buildings and over water. This was combined with a detailed manual QA/QC process, with emphasis on accurate representation of docks and bare-earth within 2000ft of the water bodies surrounding each of the five boroughs.

Pursuant to New York City’s Housing Maintenance Code, the Department of Housing
Preservation and Development (HPD) collects registration information from owners of
residential rental units. Owners are required to register if they own residential buildings

Rat Information Portal Data Release Notes April 20, 2015

The Rat Information Portal (RIP) is a web-based mapping application where users can view rat inspection data.

Data sources: NYC Department of Health and Mental Hygiene (DOHMH), Division of Environmental Health Pest Control Database

Notes on data limitations: Please note that if a property/taxlot does not appear in the file, that does not indicate an absence of rats - rather just that it has not been inspected. Similarly, neighborhoods with higher numbers properties with active rat signs may not actually have higher rat populations but simply have more inspections.

New York City school level College Board SAT results for the graduating seniors of 2010. Records contain 2010 College-bound seniors mean SAT scores.

Records with 5 or fewer students are suppressed (marked ‘s’).

College-bound seniors are those students that complete the SAT Questionnaire when they register for the SAT and identify that they will graduate from high school in a specific year. For example, the 2010 college-bound seniors are those students that self-reported they would graduate in 2010. Students are not required to complete the SAT Questionnaire in order to register for the SAT. Students who do not indicate which year they will graduate from high school will not be included in any college-bound senior report.

Students are linked to schools by identifying which school they attend when registering for a College Board exam. A student is only included in a school’s report if he/she self-reports being enrolled at that school.

Data collected and processed by the College Board.

The Bus Breakdown and Delay system collects information from school bus vendors operating out in the field in real time. Bus staff that encounter delays during the route are instructed to radio the dispatcher at the bus vendor’s central office. The bus vendor staff are then instructed to log into the Bus Breakdown and Delay system to record the event and notify OPT. OPT customer service agents use this system to inform parents who call with questions regarding bus service. The Bus Breakdown and Delay system is publicly accessible and contains real time updates. All information in the system is entered by school bus vendor staff.

Property owners are required to obtain bedbug infestation history from tenants or a dwelling unit owner. This dataset captures the bedbug infestation history as reported by the property owner.

Local Law 69 of 2017 requires that all multiple dwelling property owners must attempt to obtain the bed bug infestation history from the tenant or unit owner, including whether eradication measures were employed for a bedbug infestation. The information reported in this file is self-reported information filed annually by property owners. Once the Bed Bug Annual Report has been filed, the property owner is required to either provide the filing receipt to each tenant (upon commencement of a new lease and with each lease renewal) OR post the filing receipt in a prominent location in the building. In addition, the property owner must either distribute to each tenant or post the DOHMH Preventing and Getting Rid of Bedbugs Safely guide, which provides information on the prevention, detection, and removal of bedbugs. Each record in the file represents a filing completed. If a property has submitted two records for the same period, the second filing is the active final submission for the period.

Elevation points were captured for all building footprint features.
