2. History of Rock Creek Park At approximately 2,100 acres and 125 years old, Rock Creek Park is one of the oldest and largest naturally managed urban parks in the United States; providing protection for a variety of native plants and wildlife. Congress established Rock Creek Park, one of the first national park areas, on September 27, 1890 as a unique natural park, providing a great variety of recreational opportunities for visitors and residents of the Washington, D.C. metropolitan area.

3. Existing Conditions The last rehabilitation of Beach Drive occurred in 1991, and the pavement has surpassed its 20 year service life. It has deteriorated to a point where patching and repairs are no longer cost effective. It is classified as being in poor condition. It no longer provides the level of safety and quality people have come to expect and deserve from the National Park Service E X P E R I E N C E Y O U R A M E R I C A

4. Existing Conditions Continued Beach Drive is 6.5 miles long and bisects Rock Creek Park from north to south between the Maryland state line and Rock Creek and Potomac Parkway.

17. DC Water Sewer line Rehabilitation  DC Water owns a number of sewer assets on National Park Service properties. One of them is the Rock Creek Main Interceptor which runs along Beach Drive in Rock Creek Park.  In the next 3 to 5 years, DC Water plans to install a new liner throughout the entire length of the existing sewer line.  In order to reduce future impacts of the Rock Creek Main Interceptor and the road structure of Beach Drive, DC Water will construct and install additional manhole vaults at strategic locations along Beach Drive starting at Phase 3 and heading north to the Maryland state line.

18. DC Water Sewer Line Rehabilitation Continued  During road rehabilitation, 1 manhole vault will be constructed in Phase 3; 4 manhole vaults will be constructed in Phase 4; and 11 manhole vaults will be constructed in phase 5.  The construction of the proposed manhole vaults during the road reconstruction will allow DC Water to rehabilitate The Rock Creek Main Interceptor and Beach Drive Sewers at a later date without cutting the asphalt of the newly constructed road.  DC Water plans to advertise the manhole vault construction project in Spring 2016.
