Holiday Party Cancelled for December 3rd

Due to a booking problem we had to cancel the holiday party for this year. We plan to have a community event this coming spring. We hope you have an enjoyable holiday season.

HCA Membership

Although we do not have mandatory annual dues we are still a very active and busy neighborhood association with a history that goes back decades. Each year we solicit a voluntary $20 dues contribution from all households in the greater Hillandale community. This money goes to cover our basic operating expenses each year and maintain a reserve fund. It also helps to pay for community activities such as the holiday party and National Night Out.
