NYCDCP Manhattan Bike Counts - Off Street

The Transportation Division of the New York City Department of City Planning (NYCDCP) has performed annual bike counts in Manhattan since 1999. The counts have been conducted along designated bicycle routes at 10 on-street and 5 off-street locations during the fall season. These locations have remained generally consistent. The data collected includes cyclist/user volumes, helmet usage, use of bike lane, gender, etc. The bike counts data can offer insights into the overall trends in user demographics and travel patterns over time.

DCM_CityMapAlterations

The Digital City Map (DCM) data represents street lines and other features shown on the City Map, which is the official street map of the City of New York. The City Map consists of 5 different sets of maps, one for each borough, totaling over 8000 individual paper maps. The DCM datasets were created in an ongoing effort to digitize official street records and bring them together with other street information to make them easily accessible to the public. The Digital City Map (DCM) is comprised of seven datasets; Digital City Map, Street Center Line, City Map Alterations, Arterial Highways and Major Streets, Street Name Changes (areas), Street Name Changes (lines), and Street Name Changes (points).

All of the Digital City Map (DCM) datasets are featured on the <a href="https://streets.planning.nyc.gov/about">Streets App</a>

All previously released versions of this data are available at BYTES of the <a href="https://www1.nyc.gov/site/planning/data-maps/open-data/bytes-archive.page?sorts[year]=0">BIG APPLE- Archive </a>

Updates for this dataset, along with other multilayered maps on NYC Open Data, are temporarily paused while they are moved to a new mapping format. Please visit https://www.nyc.gov/site/planning/data-maps/open-data/dwn-digital-city-map.page to utilize this data in the meantime.

HHS Accelerator Prequalified Providers

Provider organizations that have been prequalified to compete for City funding in specific health and human services areas. In HHS Accelerator, the City's system for procuring health and human services, prequalification is based on: experience providing the service; a key staff member able to provide the service; or a capability statement describing the organization's ability to expand into the service area. Prequalification in a service area does not necessarily indicate that an organization currently provides the service at this time. Addresses provided below indicate the organization's administrative office, and may not be the location at which services are provided. For more information on HHS Accelerator prequalification process, visit http://www.nyc.gov/html/hhsaccelerator/html/application/application.shtml

Resident Economic Empowerment and Sustainability (REES) for NYCHA Residents – Council District - Local Law 163

This dataset contains information about the New York City Housing Authority’s (NYCHA) Office of <a href="https://www1.nyc.gov/site/nycha/residents/rees.page">Resident Economic Empowerment and Sustainability (REES)</a>. REES supports NYCHA public housing and Section 8 residents’ increased income and assets through programs, policies and formal partnerships in the areas of employment and advancement, adult education and training, financial literacy and asset building and resident business development. Each row in the dataset represents the number of public housing residents on a City Council District level who receive or utilize this service. Data on interagency collaborations such as Jobs-Plus and Business Pathways are not part of this data but are accounted for in NYC Business Solutions and Human Resources data respectively. As per HUD regulations REES serves NYCHA public housing, NYCHA Section 8 and Section 3 residents.

The dataset is part of the annual report compiled by the Mayor’s Office of Operations as mandated by the <a href="https://legistar.council.nyc.gov/LegislationDetail.aspx?ID=2745761&GUID=2A9FB1D2-A1A8-4484-9D49-6F8332171B66">Local Law 163 of 2016</a> on different services provided to NYCHA residents.
