The Gotham Gazette is an online publication of the Citizens Union Foundation of the City of New York, a government watchdog group focusing on issues confronting New York City.
 Its purpose is fourfold: it reports daily on New York City news, it provides a digest of news items relevant to New York City, it researches and recommends policies considered by the New York City Government, and it provides reference tools for students of the civic activities of New York.
 Its reference resources range from policy papers to indexes of proposed and passed legislation of the New York City Council.
 The "Gotham Gazette" was founded in 1999.
421-a tax abatement is a property tax abatement in the state of New York that is given to real estate developers for building new multi-family residential housing buildings.
 The program gets its name from being from section 421-a in the New York Real Property Tax Law.
 The 421-a program began in 1971, and has since included provisions in it to mandate the creation of affordable housing units in order to qualify for the program.
 Under the original program, areas in which developers qualified for the tax break included all of Manhattan and portions of the rest of New York City.
 The original program lapsed in January 2016 after disagreements between the state government and the New York City government, but a deal was made in November 2016 between unions, developers, and Governor Andrew Cuomo to bring it back, pending the approval of the New York State Legislature.
 In the April 2017 budget negotiations, the program was officially renewed, with the official new program name being "Affordable New York".
 The program is administered by the New York City Department of Housing Preservation and Development (HPD).
 Under the program, the city government stands to lose billions of dollars in foregone property tax revenue, making this program controversial.

Thomas P. Ryan Jr. (December 3, 1928 – March 14, 2003) was the 63rd Mayor of Rochester, New York.
 Ryan began his tenure as Mayor under the old council/city manager system of government, in which the mayor was selected from among members of City Council to be that body's presiding officer.
 He first was voted to the post by his Council peers after the 1973 election which returned a Democratic majority to office.
 For his first decade as Mayor, a city manager appointed by City Council and accountable to that body handled the day to day administrative duties of government.
 This system had been in place since the late 1920s as a result of government reforms championed by the late industrial magnate George Eastman.
 However Ryan, who had exercised greater de facto influence over city policy than most of his predecessors under this system and functioned in many respects like a chief executive in policy matters, championed a change in the city charter to abolish the post of city manager and return to a "strong mayor" system like that in other major cities of New York State, in which the mayor was directly elected, directly accountable to voters and served as chief executive of city government.
 The charter change was approved by city voters and Ryan served as a "strong mayor" for two terms from 1985 through 1993 before retiring from public life.
 In addition to the revision in city government structure which began during his terms of office and continues in force today, Ryan became known for helping lead significant downtown redevelopment, and operating government on a fiscally conservative basis.
