Loch Raven Boulevard Streetscape
Baltimore County, Maryland
Wallace Montgomery provided design and construction plans, specifications and cost estimates to reconstruct and improve a 1.3 mile section of Loch Raven Boulevard from Goucher Boulevard to Joppa Road in Baltimore County. The reconstruction was to provide corridor improvements and visual enhancement to this unique area of commercial and residential land use. Work involved reconstruction and resurfacing of streets, median widening, median crossover closure, sidewalk treatment, signal reconstruction, curb and gutter, storm drain inlets, and adjustment to affected utilities. A southbound lane was eliminated – replaced by the widened median and left-turn bays. Improvements included provisions for motorists and pedestrians, particularly through ADA compliance. An important feature of the project was to design a service road to provide adequate MTA bus service access, to buffer the residential area and to allow adequate parking.
Road/Intersection Design: The roadway corridor was rehabilitated to include new curb, gutter, sidewalk and pavement resurfacing. The parallel service road (maintained by Baltimore County) was redesigned to serve parking and bicycle traffic. Pedestrian design was accommodated through a very progressive and creative approach to intersection design, where ADA compliance was achieved. The design included curbline bumpouts, a widened median that served for pedestrian refuge and APS signals. Traffic calming was introduced through reduction of lane width and elimination of a southbound lane.
Landscape Architecture Design: WM worked hand-in-hand with the landscape architects to provide site furniture design at key intersections, public spaces and MTA bus stops, including benches, trash receptacles and more. Brick pavers, sustainable plantings and greening of the corridor were important project elements.
Water Resources Design: The closed drainage system was improved to meet criteria with new inlets and pipe connectors – without the need for replacement of major storm drains. Stormwater Management approval was achieved through practices consistent with an approach ESD including removal of existing pavement. Erosion & Sediment Control features required daily stabilization and routine devices.
Environmental Permitting: Permits for SWM and E&S were through coordination with MDE. The need for extensive H&H computations was avoided by documenting that imperious areas were reduced at points of discharge. DEPS (DEPRM) was also an important project stakeholder since work on County Roads was required.
Utility Design: The project required significant relocation of utility poles because of direct impacts from design and in order to achieve full ADA compliance. Minor impacts to underground facilities were required from storm drain construction. WM coordinated all utility relocations.
Structural Design: Storm drain connections from new pipes to existing facilities required special structures which were detailed and included in construction documents. Retaining walls were studied and avoided through use of slope grading.
The Loch Raven Boulevard project is a true success story, bringing together the values and concerns of six independent community organizations all represented on the Task Force – plus a large business umbrella organization. Additionally, special interests representing ADA, bicycle and commuter traffic were involved in project development. Regular meetings with local merchants, elected officials and business leaders (Task Force) were required to achieve consensus. Coordination of design issues with Baltimore County and the Mass Transit Administration was critical to project success.
