Quality of Life

1065 Park Avenue have been given the a light by the city to continue/complete their 5 year plaza restoration and side walk replacement.


For more than a decade, our Streetscapes initiative has been improving the beauty and quality of life for residents of Carnegie Hill.  Our Streetscapes manager walks the neighborhood daily looking for damage, graffiti, potholes and other nuisances that need repair.  CHN regularly repairs all municipal property – from lamp posts to benches – and we work with building managers and property owners to facilitate repairs to private property.  Examples include 3 new trees planted on 95th Street between 5th and Madison Avenues, repainted lamp posts and mailboxes and new tree guards and sidewalks installed along the south side of 90th Street between 5th and Madison Avenues.

If you see an issue that needs resolving, please contact us.  Also, you should contact 311.  By clicking on the link above and you will be directed to the appropriate agency and will receive a code number for the relevant issue.  Please call us with that number and we will work on a resolution.

Tree Care and Tree Guards

The Tree Care committee co-chairs are Julia Bradford, Suzanne Goldstein, and Virginia Pitman. Carnegie Hill residents see their team on Saturday mornings in the spring and fall pruning trees. However, they do a lot more where their hands are not so visible. CHN surveyed empty tree sites in Carnegie Hill as well as on an almost barren Third Avenue and applied for new trees through MillionTreesNYC. As a result, there are more than 180 new trees in the Carnegie Hill area, both in newly created and formerly empty beds. More empty tree beds in Carnegie Hill will be filled in the near future. To report a dead tree, please call 311.

Here is some advice from MillionTreesNYC about planting in street tree beds:

1. Use perennials, annuals and bulbs
2. Tree health comes first
3. Choose plants that require little water
4. AVOID planting bamboo, ivy, vines, woody shrubs or evergreens. They all require a lot of water and can harm the tree

Tree Guards

Tree guards are the best way to protect street trees. The NY Tree Trust, created by the Parks Department in 1997 to foster public/private partnerships, now offers an option to provide guards in our neighborhood through a tax-deductible contribution to the Trust. These guards are attractive, available in both steel and aluminum, are three-sided and slope down on the street side, making them less likely to be damaged by vehicles. Information on how to purchase a guard is available here.

There are 11 designs to choose from, and prices range from $525 to a little over $1,000 for a 5’ x 5’ tree bed. A variety of tree guards available can be viewed here.  Contact James Kaechele of the NY Tree Trust at, who can assist you in choosing your preferred tree guard design. Be a Carnegie Hill Neighbors Tree Guard-ian! CHN will thank you in the Carnegie Hill News.

Park Avenue Malls

Until 1980, the ten Park Avenue median islands in Carnegie Hill were barren dog runs until Carnegie Hill Neighbors landscaped and made them the focal point of the avenue. For more than 30 years, we have engaged gardening professionals to plant and maintain the malls between 86th to 96th streets year-round.
CHN also provides watering to the pocket park on Park Avenue between 96th and 97th streets and a recent significant donation of the hedges along the ends of several medians has further enhanced the malls.

Park Avenue Malls Chair Susan Gottridge monitors the choice and health of the plantings on the malls. CHN administers the planting of the seasonal flowers and maintenance of the grass, hedges, and trees with funds provided by the 30 boards of the cooperatives and condominiums along Park Avenue through a type of “conservancy” fund initiated by CHN in 1979. Since 2008, other buildings on Park Avenue and the adjacent side streets have contributed.

Clean Streets and Green Spaces Initiative

Our CHN Clean Streets initiative began in late 2017 to supplement the NYC Sanitation Department with weekly maintenance including continual sweeping up of street litter and bagging the trash bin overflow on Carnegie Hill’s commercial streets. The program has expanded to a hands-on training program in landscape gardening. We now maintain a once overlooked green gem of Carnegie Hill; the 97th Street mall garden. Under the guidance of our advisors, Lynden Miller Mark Goldsmith and Crista Carmody, the CHN Clean Streets team now cares for the garden with regular planting, watering and weeding.

This inspiring program is made possible through valued community partnerships with:
