**Abstract Text**
Oklahoma City's historic 16-acre Memorial Park was established in 1902 and in 1920, remade and rededicated to honor "soldiers of all wars and those of future wars." Winding concrete pathways bear the 1941 seal of the Works Progress Administration. The Memorial Park Recreation Center, built in 1954, became home to the Boys & Girls Club of Oklahoma County in 1995. Memorial Park was transformed in 2007 when Oklahoma City voters approved a $1.9 million revitalization package that funded improvements such as tennis and basketball courts, inclusive playground equipment, and upgrades to the small parking area on the north side of the park.  Construction of the new parking lot introduced pervious pavers and bio-infiltration to better manage storm water runoff quality and quantity. 
After construction, staff monitored the site to ensure the new features had the capacity to efficiently drain runoff accumulations. Staff observations indicated that excessive runoff from the lot caused scouring of the ornamental gardens on the south side of the parking lot. Staff developed a retrofit design and received funding from an AARP Community Challenge Grant in 2021 that partially funded upgrading the existing ornamental gardens with bio infiltration features. City staff labor and private donations provided the remaining project work which was not funded through the grant.
This presentation will highlight the unique features and park history, the improvements that were funded in 2007, and describe the bio infiltration upgrades completed in 2021.

The International Low Impact Development Conference highlights interdisciplinary practice, research, and implementation of Low Impact Development (LID), Green Infrastructure (GI), Sustainable Urban Drainage Systems (SUDS) and Water Sensitive Urban Designs (WSUD). The focus will be on using our past and present understanding of LID to tune management programs, design practice, and operation and maintenance into the future.
