Re: Merrimack College Project Manager Campus Parking Improvements Site Plan Review-Traffic&Circulation Memorandum Merrimack College is planning a rehabilitation and expansion of the existing parking lot along Aherne Road within the Merrimack College Campus, known as Campus Lot C. Upgrades are proposed to repair failing conditions of the existing pavement, revise the parking lot and drive aisle configuration to improve vehicular and pedestrian circulation, and formalize parking for approximately 127 vehicles that consistently park on grassed areas surrounding the current parking lot in this area. Currently, overflow parking consistently occurs during the school years in non-designated grassed areas. The goal of the expansion is to provide proper paved parking spaces for vehicles that are already on campus in a more formalized and safer manner. VHB has prepared this memorandum to summarize the proposed design and discuss access and circulation on the Campus in the area of the Project. Access: Both external access to the College and internal access to Parking Lot C from within the Campus will remain unchanged by the proposed rehabilitation Project. Access is currently provided by existing Campus roadways including Walsh Way via Route 125/114(Turnpike Street) and Medina Drive via the Campus entrance on Elm Street. The Project also proposes to relocate accessible parking spaces to be more centralized to the accessible entrances of the adjacent buildings of Sullivan Hall,the Mendel Science Center, and McQuade Library. Accessible parking spaces are designed in conformance with the American with Disabilities Act (ADA) regulation. On-Site Circulation: The Project provides substantial improvements to circulation of the existing Parking Lot C by establishing a separated parking bay, offset from the reconfigured drive aisle. The improvements include additional head-in parking off of the drive aisle to service the adjacent buildings which is also proposed to be utilized for accessible parking. Attachments A and B have been included for comparison of the existing and proposed lot configurations and circulation. Fire and emergency vehicle access to the existing buildings is improved with the reconfiguration of the lot and 25-ft.wide drive aisles. 20-ft.-wide drives are also maintained on either side of Sullivan Hall as well as through the horse-shoe drop-off loop,and parking adjacent to these drives has been tailored back to ensure sufficient room for fire truck turning movements. A collection of fire truck turning figures is included in Attachment C for confirmation of emergency vehicle access within the Site. 101 Walnut Street PO Box 9151 Watertown, MA 02472-4026 \�vhblprellwat-LD111625,16 Merrimack Parking\docs\mernos\Campus Parking-Traffic,Access&Circulation Mernorandum.dou P 617.924.1770 Ref: 11625.16 June 8,2018 Page 2 The Project also proposes to provide a new pedestrian sidewalk along the campus-side of the parking lot, as well as a mid-block crossing to the new and separate parking bay. Traffic: As noted above, the Project Site is currently utilized for a substantial amount of overflow parking to meet current on-Campus demands. The Project does not propose to introduce any source of traffic generation, merely stabilizing and improving the Site to meet current parking demands by getting parking off grassed areasp. Included in Attachment D is an index plan and associated site photos documenting the current overflow parking conditions. It is the College's intent to formalize this overflow parking and repair the existing lot to improve safety, stormwater management, and aesthetics along the Campus'front door to the Town of North Andover.
