M. Weil NCPC File No. 7290 NATIONAL INSTITUTES OF HEALTH (MAIN CAMPUS) BASE REALIGNMENT AND CLOSURE ACT, MARYLAND STATE HIGHWAY ADMINISTRATION INTERSECTION IMPROVEMENTS 9000 Rockville Pike Bethesda, Montgomery County, Maryland Submitted by the United States Department of Health and Human Services, National Institutes of Health November 22, 2011 Abstract The National Institutes of Health has submitted a proposal for multiple campus improvements to accommodate planned modifications to Maryland Route 355 (Wisconsin Avenue / Rockville Pike), West Cedar Lane, Cedar Lane, and Jones Bridge Road. The planned accessibility and safety improvements are federally-funded to help improve access to the recently expanded Walter Reed National Military Medical Center at the Naval Support Activity - Bethesda Campus. The proposal includes temporary construction and perpetual utility easements on NIH property to facilitate construction activities and to enable utility maintenance after completion of the project. Commission Action Requested by Applicant Approval of preliminary and final site development plans pursuant to 40 U.S.C. § 8722(b)(1). Executive Director’s Recommendation The Commission: Approves the preliminary and final site development plans for improvements to the National Institutes of Health (Main Campus), to accommodate the BRAC-related planned modifications to Maryland Route 355 (Wisconsin Avenue / Rockville Pike), West Cedar Lane, Cedar Lane, and Jones Bridge Road, in Bethesda, Montgomery County, Maryland as shown on NCPC Map File No. 3101.20(38.00)43423. Notes that the applicant and the Maryland State Highway Administration have fully coordinated the proposed campus improvements and roadway modifications with state and local agencies and the surrounding community through presentations made at the BRAC Implementation Committee and NIH’s Community Liaison Council. NCPC File No. 7290 Page 2 * * * PROJECT DESCRIPTION Site The National Institutes of Health (NIH) main campus is located at 9000 Rockville Pike in Bethesda, Maryland, just north of the Bethesda Central Business District. The campus is bounded on the east by Maryland State Route 355 (MD 355), on the north by West Cedar Lane, on the west by Old Georgetown Road (MD 187), and on the south by residential development, as shown in the following graphic. Background As a result of the 2005 Base Realignment and Closure (BRAC) recommendations, the Walter Reed Army Medical Center (WRAMC) located in Washington, D.C. was closed and military medical services in the National Capital Area (NCA) were realigned between two primary facilities. The formerly-named National Naval Medical Center (NNMC) in Bethesda, Maryland was expanded and renovated to serve the northern half of the NCA. At the time of the relocation, recently completed on September 15, 2011, the expanded NNMC became a tri-service facility and renamed, the Walter Reed National Military Medical Center, Bethesda (WRNMMC) and is located on the Naval Support Activity - Bethesda Campus (NSAB). The BRAC action resulted in approximately 10,200 assigned Base personnel at the WRNMMC (+2,200 Base personnel), and will nearly double the annual number of patients and visitors. NCPC File No. 7290 Page 3 The Commission approved the Master Plan Update 2008 for the NNMC at its February 5, 2009 meeting (to reflect the BRAC expansion) as well as several recent gate improvement projects. The following graphic (from the 2008 master plan update) shows the NSAB Campus’s expansion projects and gate improvements. The improved gates are designed to accommodate the projected increase in future local area BRAC-related traffic, for which the project improvements included in this proposal, are designed to accommodate. The MD SHA is planning various infrastructure improvements in a project area shown in the following graphic (highlighted in orange) to help improve local area accessibility and traffic safety. The area extends from north of the MD 355/West Cedar Lane/Cedar Lane intersection, along MD 355, south to the MD 355/Jones Bridge Road intersection, and east-west along West Cedar Lane and Cedar Lane. NCPC File No. 7290 Page 4 Proposal The planned infrastructure improvements will result in a number of physical changes to the NIH campus (their locations shown in the following graphic), which are described in detail in the following sections. The project will occur in two phases during the next three years. NCPC File No. 7290 Page 5 1. Relocated West Cedar Lane Southern Curbline The planned widening of West Cedar Lane (eastbound approach) includes the relocation of the existing south curb-line by up to 25 feet to the south. Approximately 17 feet of the expansion will occur on existing NIH property. The curb relocation will expand the West Cedar Lane eastbound approach from three lanes to five lanes (two left-turn only lanes; two “through” movement lanes; and one right-turn only lane), as shown in the following graphic. In advance of the roadway widening, Montgomery County is constructing a new 10-foot wide, shared-use, concrete path to accommodate pedestrians and bicyclists on an easement on NIH property. The pathway was approved byway of delegated A\action of the Executive Director in April 2011. The roadway expansion will require the subsequent relocation of underground utilities and removal of approximately 30 trees in the vicinity of the intersection, as shown in the following graphic. The trees to be removed are reported to be approximately 15-20 years in age. NCPC File No. 7290 Page 6 The existing photograph, below left, and renderings (looking southbound along MD 355, at the MD 355/West Cedar Lane/Cedar Lane intersection) illustrate the visual impact of the proposed tree removal in the area, located within an existing 250-foot landscape buffer. The NIH campus is seen on the right side of each image. The existing photograph, below left, and renderings (looking southeast, across the northeastern corner of the NIH campus) illustrate the visual impact of the proposed tree removal from another perspective approximately 100 feet to the west of the previous vantage point, along the north side of West Cedar Lane. 2. New Shared-Use Path Segment The following graphic shows the planned new shared-use, 10-foot wide, concrete path, which will be aligned across the northeastern part of the NIH campus. Currently, pedestrians and bicyclists must utilize a narrow concrete sidewalk located directly adjacent to MD 355 and West Cedar Lane, near fast-moving MD 355 traffic. The new path alignment will provide a more direct, safer route for pedestrian/bicycle traffic across the NIH campus, both during the construction phase and after the planned infrastructure improvements are complete. In addition, the existing sidewalk located directly adjacent to the MD 355/West Cedar Lane corner will be expanded to a 10-foot width as part of the project. NCPC File No. 7290 Page 7 The new shared-use path segment across the NIH campus will utilize a re-located pedestrian bridge (presently located on the NIH campus) to traverse an existing stream, as shown in the following graphic. The existing bridge will be refurbished and relocated as part of project mitigation efforts by the MD SHA. NCPC File No. 7290 Page 8 3. Enlarged New Stream Culvert The project will construct a new enlarged storm-water culvert that is designed to accommodate a 100-year storm event, an increase from the existing culvert’s 10-year storm event capacity, to convey water under the expanded MD 355/West Cedar Lane/Cedar Lane intersection. The new facility will be primarily located on property under the jurisdiction of the MD SHA, hidden from a street-level perspective due to its 20-foot lower elevation than the street. A new safety fence/wall will be installed along the top of the culvert to prevent accidental falls, and will be partially obscured once the natural buffer vegetation has had time to mature (shown in the previous renderings). 4. Relocated MD 355 Western Curb The planned one-lane widening of southbound MD 355 will require the relocation of the existing western curb-line by approximately 10 feet to the west, three feet to the west of the existing NIH property line. The curb relocation will allow the expansion of southbound MD 355 from its current three lane configuration, to four lanes (one right-turn only lane and three “through” traffic lanes), as shown in the following graphic. The relocation will be done in part during the first phase of the project to form a bus-bay, and then completed during the project’s second phase to form a continuous turn lane between the MD 355/West Cedar Lane/Cedar Lane and MD 355/Wilson Lane intersections. NCPC File No. 7290 Page 9 5. New Shared-Use Path There is an existing eight-foot wide, asphalt, shared-use path, aligned north-south along the west side of MD 355 (shown in the following graphic). The existing path is straight, between the MD 355/North Drive and MD 355/Commercial Vehicle Inspection Facility (CVIF) driveway intersections, and meanders between the MD 355/CVIF driveway and MD 355/Wilson Lane intersections. The path will be removed and reconstructed as a new, 10-foot wide, concrete shared-use path (intermittent yellow line) to accommodate the MD 355 widening and utility relocation. The new path will be re-aligned along the inside of the North Drive and straightened between the Commercial Vehicle Inspection Facility driveway and Wilson Lane. NCPC File No. 7290 Page 10 6. Relocated Guard Booth The existing guard booth along North Drive will be relocated to the east side of North Drive, approximately 40 feet to the south of its present location. The move is necessary to accommodate the planned MD 355 widening, and will improve pedestrian safety in the area with better sight lines for both drivers and pedestrians. The new guard booth will look similar to the existing booth shown in the previous photographs.
