Editor's Note: See 42 U.S.C. § 12101 et seq.
The following parking requirements shall be applicable in the MSHD. The purpose of these parking requirements is to encourage the MSHD to be pedestrian-friendly, with alternative travel modes encouraged, including the use of bicycles and automated electric vehicles (AEVs), as appropriate. Parking requirements within the MSHD are as follows:
A. 
Location and landscaping. Parking areas and lots should be landscaped and dispersed throughout the MSHD as outlined in the Medfield State Hospital Strategic Reuse Master Plan. Parking lots should be connected with pedestrian walkways and the sidewalk and trail system. Parking lots in the Core Campus Sub-Zone shall be minimized.
(1) 
Low impact design (LID) landscaping is required for each parking area. LID landscaping plans shall denote a drainage design where 75% or more of the first 1/2 inch of stormwater runoff from impervious surfaces is treated for water quality by a combination of LID techniques in accordance with the most recent version of the Massachusetts DEP Stormwater Management Manual. Acceptable LID techniques shall include vegetated swales, rain gardens or bioretention facilities, permeable pavers, infiltration facilities and constructed wetlands. Cisterns and grey water systems that recycle stormwater runoff may also be included in these calculations. Native plants shall be used whenever possible. Invasive species shall be avoided.
(2) 
With respect to parking areas that will contain fewer than 10 spaces, compliance with respect to the design standards set forth in this article shall be determined by the Zoning Enforcement Officer.
B. 
Minimum parking space requirements. Table 2 contains the minimum parking requirements for the MSHD.
C. 
Handicap access parking. All off-street parking areas with eight or more parking spaces shall contain spaces designed for handicapped access. In addition to the regulations herein, all off-street parking facilities must comply with the currently applicable Rules and Regulations of the Architectural Access Board of the Commonwealth of Massachusetts to the extent the same are in force and effect.
D. 
Shared parking. The use of shared parking to fulfill parking demand for uses with demands at different times of the day may be permitted by the plan approval authority if the applicant can demonstrate that shared parking spaces will meet parking demands by using accepted methodologies (e.g., the Urban Land Institute Shared Parking Report, ITE Shared Parking Guidelines, or other approved studies).
E. 
Reduction of parking requirement. The required amount of parking may be reduced at the discretion of the plan approval authority upon a showing that the lesser amount of parking will not cause excessive congestion or endanger public safety and that the lesser amount of parking will provide positive environmental or other benefits. The plan approval authority may consider:
(1) 
Shared use parking spaces serving uses having a peak user demand at different times;
(2) 
Age, income or other characteristics of the likely occupants that are likely to result in lower motor vehicle usage;
(3) 
Such other factors as may be considered by the plan approval authority, including whether the reduction of parking requirements is likely to encourage the use of public transportation; shared transport services such as taxicabs, ride-sharing or short-term vehicle rentals; or encourage the development to be more pedestrian-friendly;
(4) 
Impact of the parking requirement on the physical environment and historic resources of the affected lot or the adjacent lots, including reduction in green space, destruction of significant existing trees and other vegetation, significant negative impact on historic resources or impairment of the integrity of the historic MSH landscape.
F. 
Off-site parking. Required parking may be located at nearby sites within the MSHD District.
G. 
Parking maximums. The proposed amount of parking to be provided shall not exceed 180% of the minimum parking requirements set forth in Table 2.
H. 
Electric vehicle charging stations. Electric vehicle charging stations shall be provided at a ratio of one charging station per 35 vehicles.
I. 
Bicycle parking. In addition to motor vehicle parking, bicycle parking shall be provided. One bicycle parking space per seven residential dwelling units shall be provided. For non-residential uses, one bicycle parking space per 10 motor vehicle parking spaces shall be provided.

Any proposed project undergoing the plan approval process shall be subject to design guidelines as set forth in this article. The purpose of the design guidelines is to ensure that new development shall be of high quality, and shall be compatible with the character of building types, streetscapes, and other community features traditionally found in the area of the MSHD. The design guidelines may be supplemented from time to time by the plan approval authority.
A. 
Campus character and context. The Medfield State Hospital campus is a unique setting both for its historic buildings and its natural features. Characterized by a clear campus "quadrangle" atop a hillcrest, the main campus offers views of rolling hills, forested areas, and the Medfield Charles River Gateway to the west. Maintaining these viewsheds is a top priority for the site, and has informed strategies for renovation and new construction, parking and landscape planting.
(1) 
Campus setting.
(a) 
Medfield State Hospital Campus. New construction on the main campus area is limited in order to maintain consistent rhythm of perimeter buildings and views between the buildings to the surrounding landscape. New development shall be compatible in relationship to the campus context and surrounding structures in terms of solid to void massing, rhythm and spacing between buildings, setback patterns of buildings and porches, overall building massing and form.
(i) 
The viewshed between buildings, especially to the north, west and south, is to be maintained.
(ii) 
The rhythm/spacing of buildings of the Core Campus should be maintained.
(iii) 
Reuse of existing buildings and new construction should orient structures toward the primary street, and main building entries should be from the primary street. (Refer to "Frontage" in Table XII-5 for additional information.)
(iv) 
Appropriately designed additions which respect existing building features permitted at the rear of buildings.
(v) 
Additions linking buildings are permitted on the east side of the Core Campus only, where they least disrupt viewsheds.
(vi) 
Links on the east perimeter of the Core Campus should be set back from the inner street face of buildings and appear to be distinct in materials; glazing is preferred.
B. 
Historic preservation. Adherence to the Secretary of the Interior's Standards for Treatment of Historic Properties with Guidelines for Preserving, Rehabilitating and Reconstructing Historic Buildings is a core part of preservation of the Medfield State Hospital properties. Within the standards, the Secretary of the Interior's Standards for Rehabilitation provide the best guidance for the Medfield State Hospital redevelopment. Principles for preservation include:
(1) 
Removal or alteration of historic features is discouraged; repair is preferred.
(2) 
Replacement of historic materials or features should be based on evidence, and new materials should match those being replaced as best possible.
(3) 
Additions should not impact integrity of the original building if removed in the future.
(4) 
Cleaning, repair and replacement. Specific approaches for dealing with cleaning, repair and replacement of materials are as follows:
(a) 
Retain and repair original materials wherever possible.
(b) 
Replace deteriorated material with matching materials.
(c) 
Match masonry and mortar as closely as possible.
(d) 
Clean masonry with gentlest method possible.

C. 
Buildings. To address how rehabilitation and new construction projects best fit in with the established context of the campus, the design guideline criteria for buildings address massing and form, site relationships, orientation, fenestration and materials.
(1) 
Design and massing.
(a) 
Existing building character. The existing campus buildings on the MSH campus are characterized by:
(i) 
Steep-pitched, slate roofs with dormers, clerestories and chimneys.
(ii) 
A three-part massing consisting of: a base (an exposed basement/lower level), a two-story section with generous floor-to-floor heights, and a steep pitched roof.
(iii) 
Wood porches and entry stairs protrude from the main brick building massing.
(b) 
Building rehabilitation. Effort should be made to rehabilitate existing structures in order to maintain the historic campus setting. To this end:
(i) 
Building features removed over time, such as verandas, porches and entry stoops should be reconstructed or may be integrated into the building as part of new uses.
(ii) 
New construction need not replicate existing buildings, but should reflect the massing, floor heights and character of the existing buildings in order to promote a consistent appearance across the campus.
(iii) 
New construction should match the cornice height and floor-to-floor dimension of existing buildings in order to reflect the scale of the campus setting.
(iv) 
Any new construction should maintain a consistent building line relative to the street in the Core Campus area.
(v) 
New construction should maintain a distance between structures, existing or new, that is consistent with the existing Core Campus building footprints.
(2) 
Windows and doors. Guidelines for window openings and glazing, door openings and doors are as follows:
(a) 
New glazing is acceptable if elements are consistent in scale, rhythm, color, and transparency with campus setting.
(b) 
Existing door and window openings should be retained; do not enlarge or reduce size of existing openings.
(c) 
Replacement windows on existing structures should match original window mullions and details.
(d) 
Rhythm or pattern of door and window openings should be consistent with that of the original buildings.
(3) 
Materials. Material choices for new construction and renovations are important in the context of the historic campus and natural areas of Hospital Road.
(a) 
Character of existing materials in Medfield State Hospital North buildings. The current campus is characterized by brick buildings with slate roofs, and white painted wood window frames, porches and details. The brick construction incorporates detail on the cornice line and eave area, around window openings and at entryways.
(b) 
Materials for rehabilitation and new construction on MSH North. While not limited to the existing palette of existing materials, new construction should reflect the quality of construction and durability of materials in existing historic context. While some new materials may better address maintenance issues, their appearance may not be in keeping with the historic character of the campus. For this reason, materials such as vinyl siding and brick veneer are prohibited.
(c) 
Electric and gas. ENERGY STAR® - conservation-rated lighting, appliances, and heating and cooling systems should be used in both rehabilitation and new construction throughout MSHD. Renewable energy technologies, such as solar energy, geothermal, microgrids and waste heat recovery are encouraged; wind turbines and stand-alone ground-mounted solar arrays are not encouraged.
(d) 
Water. WaterSense - conservation-rated products and services should be used in both rehabilitation and new construction throughout MSHD. WaterSense products include, but are not limited to, low-flush toilets, water-reducing shower heads, and water-conserving appliances. Water-saving methods, such as capturing groundwater runoff and recycling gray water for irrigation, are encouraged.
(4) 
Roofs.
(a) 
MSH North. The MSH campus buildings are distinguished by steep-pitched, slate roofs.
(i) 
As character-giving elements of the buildings, existing hip roofs, dormers, and clerestories should be preserved.
(ii) 
Details of roof construction such as cornices, brackets, gutters, and cupolas, should be preserved.
(iii) 
Deteriorated roof materials should be replaced with like materials, or if not feasible, with materials that approximately match the existing in size, shape, color, texture, and installation method.
D. 
Infrastructure.
(1) 
Streets and sidewalks. Streets and sidewalks should be compatible with the historic fabric of the MSH campus and in keeping with the Secretary of the Interior's Standards for the Treatment of Historic Properties.
(2) 
Utilities. The impact of utilities on viewsheds and on the historic fabric of the campus should be minimized. To this end:
(a) 
Utilities and infrastructure should be installed underground so as not to impact the character of the campus or disrupt viewsheds.
(b) 
Utility infrastructure elements, such as electrical boxes, standpipes and similar items, should be located to the rear of buildings, out of view from the main campus quadrangle. Utility infrastructure elements should be screened from view with landscape treatment.
(3) 
Lighting.
(a) 
Building lighting, signage lighting and site lighting should adhere to any Dark Sky guidelines adopted from time to time by the Medfield Planning Board.
(b) 
Pedestrian-scaled lighting should be provided at paths and walks in the public areas of the main campus.
E. 
Access and parking.
(1) 
Public parking. Public parking to support public access to site is to be provided. Public parking should also be provided for visitors to residential homes and for customers of commercial and nonprofit uses.
(a) 
The primary public parking areas should be concentrated at the entry road by Building 2, and near the access point to the Medfield Charles River Gateway in the northwest corner of the property. Additional smaller-scale public parking areas should be distributed across the MSH Core Campus, West Slope and Water Tower areas.
(b) 
On-street parking is permissible per the Master Plan.
(c) 
One bump-out with vegetation is required for every 10 or fewer parking spaces.
(2) 
Building entrances.
(a) 
In the Core Campus area, primary building entrances should match the historic pattern of building stoops and porches, and be oriented toward the campus core road.
(b) 
In other areas of the MSH site, primary building entrances should be oriented toward the addressing street.
(c) 
Secondary building entrances from parking areas may be located at the rear or sides of buildings.
(3) 
Garage and parking entrances. Garage and parking entrances should be from the rear of buildings on the Core Campus quadrangle so as to support a pedestrian-oriented walkable core area and not visually disrupt the main campus circulation.
(4) 
Parking areas.
(a) 
Parking should be provided based on the Institute of Transportation Engineers (ITE) Parking Generation, 4th Edition, for average peak period parking demand.
(b) 
Ample storage area for snow removal should be located so as to not damage the campus landscape or impact the natural areas surrounding the campus.
(c) 
Parking should be screened from view and preferably located at the rear of buildings.
(d) 
Parking on the Green is limited to special event parking, if necessary.
(e) 
Shared-use parking with MSH patrons and residents should be developed in conjunction with the prospective siting of municipal recreational facilities or other uses south of Hospital Road.
F. 
Landscape. The essence of Medfield State Hospital's character lies in the contrast between the formality of the hilltop campus and the surrounding pastoral landscape. Development on the campus should respect this framework through contextual siting of buildings and appropriate enhancements to the campus landscape.

(2) 
Buffers and screening. Landscape buffers and quality screening elements consistent with the campus character and the species and variety of trees and shrubs currently in place should be used to minimize disruption of the campus environment and important viewsheds. Buffers and screening are required as follow:
(a) 
Landscape buffers should be provided at utility infrastructure, such as electric boxes, to screen them from view.
(b) 
Landscape buffers and fence screening should be provided at trash areas and maintenance areas.
(c) 
Landscape buffers should be provided between parking lots and residential uses.
(d) 
Parking areas should have tree planting areas. A minimum of one tree planting area for every 10 parking spaces should be provided; if a more restrictive requirement is outlined in any Town-wide design guidelines the more restrictive requirement shall apply.
(3) 
Trees and plantings.
(a) 
Protect and preserve the historic, mature trees that define the spaces and streets of the MSHD.
(b) 
The historic specimen tree collection is to be preserved and maintained throughout the site, and in particular in the Core Campus, the Green and the Cottage Arboretum areas.
(c) 
Invasive species should be removed, and new plant materials should be native species. In the Cottage Arboretum area new specimen plantings are encouraged.
(d) 
Tree plantings along Stonegate Drive should be restored.
(e)
