Kaka'ako Makai Gateway Park (also known as Improvement District 5) is a major public works undertaking that created an attractive six-acre park that now serves as a visible "gateway" to, and extension of, the Kaka'ako Waterfront Park.  This park is a very important component of HCDA's plans to transform Kaka'ako's Waterfront into a people-oriented center of activities to be enjoyed by Hawaii's families and visitors.  Kaka'ako Makai Gateway Park forms a dramatic view corridor from Ala Moana Boulevard to the waterfront.  Large landscaped lawns and festival grounds provide space for recreation and social activities.  Gateway Park includes a two-acre passive park and a four-acre playing field with a comfort station.

The $6.7 million project also included significant roadway and utility systems improvements on Cooke Street, between Ala Moana Boulevard and Ilalo Street.  New ater, sewer and drainage systems were installed and new driveways, sidewalks, walkways, curbs, gutters and streetlights were constructed.  The existing overhead utility lines were relocated underground.
