Tree Cover

The number of trees and the area shaded by them influences many neighborhood factors, such as attractiveness and lower summer temperatures that, in turn, encourage residents and visitors to walk and do other physical activity. “Tree canopy cover” measures the percent of a neighborhood that is covered (or shaded) by trees.

 About the Measure

Tree Canopy Cover – Percent

How Calculated: 

Tree canopy cover represents a ‘top down’ mapping perspective in which tree canopy over-hanging city features (such as sidewalks) is measured. The percent is calculated by dividing the area of tree canopy in km2 within the UHF neighborhood by the total land area (excluding inland water bodies). Higher percentages indicate greater tree canopy cover, with zero representing no tree canopy cover.

Subway Station Density

Many New Yorkers rely on the subway as their primary mode of transportation. Neighborhoods with greater subway access tend to have more foot traffic, making surrounding real estate highly desirable for residents and business. Subway use encourages active transportation (walking, biking), which improves the health of residents.

 About the Measure

Subway Station Density – Number per km2

How Calculated: 

Subway station density measure takes into account multiple route-transfer opportunities at one subway station and each stop is counted only once regardless of how many route-transfer opportunities are available at any given subway station. Density is calculated by dividing the count of MTA subways stations as of 2012 by the total land area in km2 of the UHF neighborhood (excluding inland water bodies).

NYC Water Supply

The DEP publishes an annual report on the quality and safety of New York’s amazing water supply. As you likely know, we get our water mostly from Croton and the Catskills:

The DEP has a number of ways in which you can reduce your exposure to lead:

  • Run Your Tap. for 30 seconds to 2 minutes before using water for drinking or cooking, when your water has been sitting for several hours.
  • Use Cold Water. for cooking, drinking, or preparing infant formula. Hot tap water is more likely to
    contain lead and other metals.
  • Remove & Clean the faucet screen monthly (also called an aerator), where small particles can get trapped.
  • Hire a licensed plumber to identify and replace plumbing fixtures and/or service line that contain lead.

The annual report can be found here:

More on Redlining

The digitized versions of the 1930’s redlining maps are fairly ubiquitous these days.

What is often not discussed is that in the early 20th century the white men who drew these maps predicted that the waterfront of the Upper East Side (then with breweries, warehouses, factories, and a mostly German and Slavic immigrant community) was going to go downhill. We also need to recall that the presence of the 2nd and 3rd Avenue Els were also a source of class-panic in that the depressed land values under the Els and the sorts of businesses that located there, seemed to portend a dark future.

In the illustration, above, you can see the almost complete expectation (by the redlining teams) that the Financial District and the LES + Chinatown, would invariably become ‘hazardous’ investment locations.

Redlining, however, did more than predict a community’s viability as a site of investment, it also determined community’s futures by starving them of capital and slowly consigning any existing property owners in ‘hazardous’ areas to insolvency or bankruptcy.

The Public Health Impacts of PM2.5

The Department of Health and Mental Hygene (DoHMH) has an interesting set of maps showing which communities are most impacted by small particulate matter – PM2.5 – which comes from burning/exhaust.

Fine particulate matter (PM2.5) are tiny airborne solid and liquid particles less than 2.5 microns in diameter. PM2.5 in NYC comes from inside and outside the city from all kinds of combustion activity, including the burning of fuel in vehicles, buildings, power plants, and construction equipment, as well as commercial cooking and industrial activities. PM2.5 can either come directly from these sources or be formed in the atmosphere from other pollutants.

PM2.5 is the most harmful urban air pollutant, small enough to penetrate deep into the lungs and enter the bloodstream, resulting in adverse respiratory and cardiovascular health outcomes and contributing to an increased risk of death and lower life expectancy.

In New York City, current PM2.5 levels contribute to 2300 deaths and 6300 emergency department visits and hospitalizations for respiratory and cardiovascular disease each year. 17% of all emissions come from traffic.

PM2.5 and related health problems from traffic are highest in the poorest neighborhoods in fact, PM2.5 levels from all traffic sources are 50% higher in high poverty neighborhoods relative to low poverty neighborhoods.

As a part of a FOIL request I recently sent to the Department of Homeless Services (DHS), I was given a map illustrating the number of buildings (466 in total) in which DHS provides shelter and services (as of January 31, 2021). The sidebar, next to the map, claims that there were 31% fewer buildings than the 647 buildings reported in DHS’s “Turning the Tide” in February 2017.

On the map, DHS claimed to be working to ensure that shelters are distributed equitably across the five boroughs, including in communities that do not currently have any shelters, and at the end of the text they note that the NYC DHS shelter census stands at less than 53,000.

(note the huge disparity in building totals, above)

What is interesting is that they decided to focus on the number of buildings and not the number of people in the buildings. This is especially interesting given that by including their DHS shelter census total, they’ve indicated that they do know the number of people.

Until DHS replies with the community district population totals (which they have refused to do in response to 4 FOIL requests I’ve made), it is impossible to assess the balance or imbalance, of these facilities, and how they burden some communities more than others.

Below is a close-up of the density of shelters in northern Manhattan and the southern Bronx:

And compare that to Staten Island which has only only 1 shelter (the size of which we don’t know).

Community Districts

East Harlem has many commonalities with the South Bronx in terms of population, history, infrastructure, and governmental relations.

A map of the density of opioid treatment programs (as licensed by OASAS) shows the clear linkage.

Note how CB11 (East Harlem) has the largest opioid capacity in New York City. OASAS has packed programs in East Harlem repeatedly and forced East Harlem to serve addicted New Yorkers who reside in the gray areas on the map.

To view an interactive version of the map (hover over a community district to learn the opioid capacity and district number), see below:

Lost Dog in Haarlem

In 1666, a white dog with a blind red eye was reported lost in Rotterdam. His owner placed an announcement in the “Oprechte Haerlemse Courant” offering a reward for returning the dog.

This is one of the first, published lost dog announcements ever recorded.

Oh, and NYC is How Much of America?

If you take NYC’s population, and you head out west/north to fine 8.4 million people, this is how much land you’d have to encompass:

Mental Health Program Locations

Note that Manhattan and the South Bronx have far more programs than Staten Island, Brooklyn, and Queens.

Keep in mind that both Queens and Brooklyn have larger populations that Manhattan.
