Milford Streetscape Phase 2 Concept
Rossi Group is responsible for developing transportation-related infrastructure improvement concept and engineering design to improve bicycle and pedestrian safety and mobility and to enhance aesthetics along Front Street in Milford, Delaware.
The project limits are from the NE 4th Street to North Rehoboth Boulevard for approximately 1,300 feet. The purpose of this project is to implement a ‘road diet’ and to improve bicycle and pedestrian facilities by adding a shared-use path on the north side and a sidewalk along the southside of NE Front Street. The Phase 2 concept aims to be a continuation of Phase 1, a road diet type improvement of NE Front Street Streetscape Improvements from N. Washington Street to NE 4th Street. All proposed improvements are anticipated to be fully ADA accessible.
Project Need and Funding
The increasing number of pedestrians and bicyclists using the street network and shoulders dictate the City’s consideration of walking and bicycling as a significant mode of non-motorized transportation. The purpose of the project was to improve access for pedestrians and bicyclists to downtown businesses and planned shared-use pathways, to provide ADA compliant facilities including sidewalks, a pedestrian and bicycle pathway, and improved intersections crossings that enhance pedestrian and bicycle safety while maintaining vehicular through the corridor.
The project is funded through and managed by the Delaware Department of Transportation, Transportation Alternative Programs grant with funding match by the State and the Town of Milford. All state and federal requirements and processes associated with the grant funding are coordinated to meet eligibility.
Rossi staff conducted field reconnaissance to observe current pedestrian and bicycle facility conditions and challenges; collected information regarding bicycle and pedestrian conditions, available accident and traffic data, existing environmental features (stream crossing), public park land, property and right-of-way mapping, and identifiable utility conflicts. Rossi prepared the highway, property, and environmental base mapping from GIS data and aerial mapping. Additionally, Rossi reviewed previous bicycle and pedestrian studies, traffic counts, accident data, and relevant comprehensive and master plans and proposed development plans to ensure compliance and conformity. Rossi coordinated with the Phase 1 project team to ensure continuity between the design sections.
Concept Development and Engineering Design
Rossi developed a complete streets road diet plan that promotes bicycle and pedestrian safety and mobility for all users and is consistent with applicable comprehensive, strategic, and master plans. Design elements proposed were based on established roadway and urban design best practices and complete streets guidance and followed the local and state design criteria and manuals.
The concept is presented on existing aerial base maps of the project area and shows the tie in to Phase 1. Rossi evaluated the concept with respect to the Americans with Disabilities Act (ADA) standards in an effort to provide feasible design and to meet current regulations. The proposed improvements considered include: new shared-use pathway, new or improved sidewalks, new or improved bicycle facilities (sharrows, bike lanes, signing, markings), crosswalks and ADA ramps, curb and gutter and mountable curb with raised islands, and signing and striping.
The proposed streetscape/landscape elements include: crosswalks in thermoplastic materials and colored pattern; location appropriate native landscaping strip and plantings as a vegetation management practice within the right-of-way to improve roadway safety and aesthetics; bicycle facilities including bike racks and bike parking; stormwater management best management practices (BMPs) to treat highway runoff; materials include permeable materials and planted landscaping and grading areas.
Rossi evaluated an at grade sidewalk/mountable curb to allow for parking lot ingress/egress of trucks at two commercial businesses while ensuring proper delineation of vehicular and pedestrian / bicycle travel. Rossi investigated the feasibility and type of pathway improvements required to accommodate a typical roadway section with specific pathway features (curb backing, railings, visual delineators) at the culvert crossing of the tributary of Mispillion River.
The culvert improvements may include structural design of endwalls and cross culvert and are coordinated with other DelDOT statewide initiatives. Rossi prepared a typical section showing the proposed improvements within the existing right-of-way based on GIS data. Rossi will further investigate and prepare easement and plats (as necessary) during the final design. Rossi prepared an engineer’s construction and Capital Improvement Plan cost estimates for grant funding match. The road diet design utilized AASHTO Guide for Development of Bicycle Facilities, DelDOT Bicycle Policy and Design Guidelines, and the AASHTO Policy on Geometric Design of Highways and Streets. Bentley Microstation V8i was utilized for the engineering concepts following DelDOT CADD standards.
Rossi will coordinate and facilitate a public workshop in conjunction with the Town Council meeting. Rossi will develop various graphic display boards and materials to effectively communicate the proposed enhancements to the general public and Council members. Rossi will present at the public workshop and collect and summarize comments received. Rossi will prepare a project summary report documenting the existing conditions, proposed improvements, community input, and costs.
