Office of the Deputy Mayor
for Economic Development and Rebuilding
Memorandum
Date: April 29, 2002
To: Air Quality Task Force
From: Laurel Blatchford
Re: Indicators
As per our discussion regarding effective indicators to mark our progress, I have
included below a list of economic and quality-of-life statistics that are measured over
time. These are in addition to the scientific indicators that will be used by members
of this task force to measure changes in Lower Manhattan’s air quality environment
over the long term.
Please review these indicators and let me know if you think that they would be useful.
I also welcome any other suggestions for indicators to be added to the list.
There has also been some discussion about the appropriate timing of any progress
measurements. All of the indicators below are gathered at different times, so
synchronizing them in any way would be very difficult. My suggestion would be that
the Task Force decide how regularly it wants to collect information, and then do so
while taking into account the variation in data collection for each of the indicators
below.
• Applications for new business incorporation in Lower Manhattan (available from
NY Department of State)
• Asking rents in Lower Manhattan for residential and commercial space (Cushman
& Wakefield)
• Businesses (number open in each sector now vs. pre Sept. 11^'^ - available from
organizations like the Downtown Alliance that canvass area businesses
(particularly retailers) as part of their service)
• Commutation numbers (Number of bridge crossings, ferry ridership, public
transportation users - available from the MTA, NYS DOT, NYC DOT)
• Food service permits (Available from DOH)
• Hotels open/occupancy rates (Available from NYC & Co.)
• Pedestrian counts along major streets (Available periodically from organizations
such as the Downtown Alliance)
