Simultaneously during the 1880s, the quality of Prospect Park had declined through overuse and a corresponding lack of maintenance. After Brooklyn Mayor Alfred C. Chapin walked through the park in 1888, he requested that $100,000 be allocated for improvements. Subsequently, the Brooklyn Parks Commission embarked on a $200,000 program to restore the park. It repaved many of the walkways and drives, as well as replanted flora. The Commission also proposed purchasing the land around the Mount Prospect Reservoir, northeast of modern-day Prospect Park, which had been excluded from the final plan for the park. Instead, this space was developed as the Brooklyn Museum in the 1890s, followed by the Brooklyn Central Library and Brooklyn Botanic Garden in the early 20th century. The reservoir was filled in, and along with Mount Prospect Hill, became the separate Mount Prospect Park in 1940.
