Rock Creek Regional Park consists of 1,810 acres in Montgomery County, developed in the 1960s for lake-oriented recreation and flood control. Lake Needwood is a 75-acre man-made impoundment lake located along Needwood Drive near Rockville, and according to M-NCPPC, “is one of the crown jewels of Rock Creek Regional Park.” In addition to the picturesque lake on which visitors can boat and fish, the park features a golf course, hiking trails, playgrounds, picnic areas, an archery range, a visitors center, and snack bar.

The Park Development Division (PDD) of the Montgomery County Department of Park and Planning of the Maryland-National Capital Park and Planning Commission (M-NCPPC) has retained URS Corporation (URS) of Gaithersburg, Maryland under Task Order No. MC 2005-03 for the preparation of a Facility Plan for restoration and improvements to the on-site sewer line serving Lake Needwood within the Rock Creek Regional Park system.


The existing on-site sewer system, which was built in the 1960s, serves the visitors center, three bathhouses, and the Maintenance Yard. The system consists of approximately 6,750 feet of gravity sewer, approximately 1,000 feet of force main, 34 manholes, and two ejector-pump stations. The Maintenance Yard is not connected to the sewer line and has its own septic system and drain field.

Project Scope

The goal for this Facility Plan is to generate innovative, economical, and environmentally sensitive options for the restoration or re-design of the existing sewer lines. Ultimately, the Facility Plan will include 30 percent complete construction documents consisting of a design, cost estimate, and determination of regulatory feasibility. Based on detailed site investigations and review of existing data, URS will investigate three alternatives for restoration or replacement of the sewer line, and recommend the most viable alternative to M-NCPPC for more detailed design.

The scope of this project has been delineated into three tasks that will accomplish these goals:

  • Task One – Project Initiation Phase
  • Task Two – Facility Planning Phase
  • Task Three – Facility Plan Approval Phase

The attached Facility Plan summarizes the results of Task One and the design alternatives phase, and permit and approval phase of Task Two. This Plan will be submitted to the PDD Committee for review and selection of the preferred alternative. This Plan will be prepared as a Draft Final and submitted for review by all pertinent M-NCPPC stakeholders. Once reviewed by all M-NCPPC stakeholders, a Final Facility Plan will be prepared and presented to the Planning Board.
