Project Description

This project renovates and replaces the existing playground just north of the intersection of Dennis Avenue and Sligo Creek Parkway, between Sligo Creek and Sligo Creek Parkway. The project seeks to move the playground outside of Sligo Creek’s 100-year floodplain, while still keeping it in close proximity to the Park Activity Building. This project is being coordinated through the Parks Playground Renovation Progam.


The wooden composite play structure, spring rockers and swings adjacent to Sligo Creek are heavily used by neighborhood residents and Park Activity Building users alike. Last renovated in 1990, the play equipment has reached the end of its life expectancy. The playground’s location within Sligo Creek’s 100-year floodplain creates maintenance challenges, as the site floods regularly, washing the engineered wood fiber mulch out of the play area and damaging the equipment.

Parks staff studied several alternate locations for a new playground in the park, including sites on the west side of Sligo Creek. The parking lot immediately south of the Park Activity Building was ultimately selected to be the site of a new playground because of its location outside of the 100-year floodplain and its proximity to the Park Activity Building, parking, and other park amenities. In order to maintain the park’s existing parking capacity, new pull-in parking spaces will be created along the west side of Sligo Creek Parkway, similar to parking configurations elsewhere along the Parkway (e.g. across from the Sligo Creek Golf Course and just north of the intersection with Forest Glen Road).

Local Park Playgrounds are typically around 5,000 square feet in size and include playground equipment to meet the needs of children ages 2 to 12. Typical types of equipment include swings, composite play structures with slides and freestanding pieces of equipment such as spring rockers and spinners. The playground will be compliant with the Americans with Disabilities Act (ADA) and adequate seating will be provided around the playground’s perimeter for caregivers. Construction of the project will likely be phased so that all facilities remain open throughout. Work will be coordinated with ongoing ADA site work.

Status/Project Update

Parks completed a public comment period via the Open Town Hall forum. The public consulted in selecting the best design for the new playground.  Staff is developing the final design for approval.
