Quarry Pond Patio to Provide Shady Oasis for Students

Flat Rock Brook is moving forward with an exciting Quarry Pond patio renovation this spring—a project that will ultimately provide a shaded workspace for students attending field trips and summer camp at Flat Rock Brook. Currently, there is no shaded workspace for students to complete studies of water quality and aquatic organisms in the pond. This patio renovation will offer students a comfortable place to immerse themselves in scientific studies and learn to be the STEM professionals of tomorrow.

Our patio renovation will feature a continuation of the blue stone paving that currently welcomes visitors into our Nature Center, seating for students to gather, native plantings acting as borders to the patio space and a retractable awning for sunny summer days. This multi-use space will be renovated up to the standards of the Americans with Disabilities Act (ADA), increasing accessibility at Flat Rock Brook.

This project is made possible by the generosity of the Bergen County Open Space Trust Fund and Trustee Cynthia Sumner. The Bergen County Open Space Grant is a matching grant and they will match us dollar for dollar up to $7,500.  Through the generosity of donors, we have raised the matching funds and plan to break ground on the project in July.

Lillian Pitkin Schenck Fund Awards Flat Rock Brook $5,500

homeschoolThe Lillian Pitkin Schenck Fund has once again committed to  support Flat Rock Brook's Environmental Education Program through a grant of $5,500. Flat Rock Brook has a long history of producing quality environmental education programming.  We have been teaching children and the public about nature and related topics for nearly 45 years. Last year, we reached over 5,100 participants with the message of the value of the natural world and their power to protect it. 

Our environmental education program offers onsite field trips and outreach that serve approximately 40 area schools from nearly thirty separate municipalities in New Jersey and New York.  Flat Rock Brook also offers a highly popular summer nature day camp. Public programs on a variety of natural history subjects are also available and open to the general public.  Our experienced staff, including an education director and staff naturalist, manages a team of volunteer trail guides that assist in delivering programs to students each year.  

Flat Rock Brook thanks the Lillian Pitkin Schenck Fund for its ongoing support that helps make this important program available to the community.
