1. Introduction

1.1 Statement of Intent The design and development requirements and criteria described in this document have been written to guide future devel-opment of the Grafton Science Park. Their intent is to facilitate and expedite development by establishing clear expectations, while mitigating the effects of development on the 84-acre site, by respecting its environmental constraints, maintaining its distinctive rural character, and complementing the historic characteristics of the campus.

1.2 Overall Design Policies Accordingly, the overall Development Plan for Grafton Science Park should reflect the following overall design policies:

• Minimize Impacts on Natural Features and Site Character. Locate and design proposed buildings to respect the natural terrain.Mature stands of trees should be preserved if possible. Minimize site disturbance and earthworks. Proposed grading should follow existing grades to the maximum extent practicable. Use underground utilities and screen the necessary aboveground utilities and appurtenances.

• Architectural Continuity with the Adjacent Cummings School CampusDesign buildings to reflect the character, color, and texture of the historic buildings on the Grafton campus.

• Avoid Impacts to Sensitive Environmental Resource AreasLocate and design the development to avoid impacts on the bordering vegetative wetlands.

• Manage Traffic Encourage pedestrian access and the use of the nearby commuter rail station. Keep roadway widths, turning radii and intersections as small as possible to discourage speeding. Create parking lots with trees and internal landscaped islands to reduce their scale. Segregate truck access and service areas to the greatest extent possible. Provide amenities that encourage bicycle use.

• Wayfinding and SafetyMaximize access, visibility and identity by creating distinct signage at the project’s entrance, and using clear directional signage and nightlighting throughout the park. Design the site illumination with the user’s perception of safety in mind, providing adequate levels of lighting in areas of pedestrian activity.

3. Development Land Use and Development Intensity

The Grafton Science Park will be developed for research, development, manufacturing and support services in the fields of: biotechnology, medical, pharmaceutical, physical, biological, and behavioral sciences and technology; environmental science, toxicology, wildlife medicine, genetic engineering, comparative medicine, bioengineering, cell biology, human and animal nutrition, and veterinary medicine, alternative and renewable energy, including offices, administrative and support facilities related to any of the foregoing activities. Facilities supporting these uses are also permitted including: animal and veterinary hospitals and clinics, restaurant and other food service facilities, conference and convention facilities, hotel, motel and other housing accommodations, library, information and telecommunication services, and facilities for banking, postal and delivery services, day care and recreation. (Refer to the Town of Grafton Zoning By-Law regarding all permitted uses.)

The maximum floor area ratio (FAR) on the entire park will be 0.35. Subject to market timing and demand, at least 50% of park uses should be research and development, with the remaining 50% in either in manufacturing uses or support facilities.

7

4. Building Design

4.1 Overall Approach

The architecture and location of new buildings in the park should be sympathetic to its existing context and reflect the character, color, and texture of the historic Grafton State Hospital (see Figure 1 and 2 below). JM Holdings Corpo-ration’s expectation is that all new buildings will be high quality commercial design and materials.

4.2 Sustainable Development

To the extent practicable, the Developer should employ new building “green” design principles and follow LEED standards. The Developer should promote sustainability by increasing energy efficiency and using renewable resourc-es, as well as reducing greenhouse gas emissions and other waste and hazardous material production.

4.3 Building Locations and Envelopes

Building envelopes were created in the approved Grafton Campus Master Plan (June 1999 and as amended), to con-ceptually define the position and extent of future develop-ment of the park. The intent of positioning development in these locations is to contextually relate to the building massing on the existing campus, respect and preserve the natural terrain, and minimize the impact to sensitive envi-ronmental features. These Building locations are illustrated in Figure 3 (Spagnolo/Gisness Conceptual Plan, September 2005). Holdings prefers that the building envelopes be the only areas within which building development shall take place. However, the square footage of development assign-able to each envelope will be a function of market demand, zoning requirements, parcel size, and the amount of parking allocated to surface and structure, if appropriate.

In siting buildings, the Developer shall avoid impacts to sensitive environmental resource areas including bordering vegetative wetlands. No building should occur within the 100- foot buffer zone wherever possible. If construction is unavoidable in the buffer zone, minimum distance from wetlands shall be 50 feet with all parking and other hard surfaces located at least 20 feet from wetland boundaries. Minimum wetlands setbacks must be consistent with Graf-ton Conservation Commission regulations, as amended.

4.4 Building Massing

To the maximum extent feasible, the Developer shall pre-pare plans for individual buildings that reflect the following principles, which are useful in the development of build-ings along the street line:

• All roof structures (including, but not limited to me-chanical equipment and skylights) shall be organized and screened in a manner that is integral to the archi-tectural form of the building.

• Entry canopies and glass shall occur at the main entry points to the building.

• Stepping roof lines and roof lines with horizontal and vertical projections shall be provided in lieu of long horizontal roof lines.

• Buildings that possess transparency (multiple win-dows) vs. privacy shall be provided.

• Exposed concrete foundation walls shall be screened by the grade or landscaping.

• Loading docks shall be concealed from the street. • Setbacks and projections shall be provided in the

building facade in lieu of long unbroken facades. • Punched windows and strip windows broken at column

lines by dissimilar materials shall be provided.

4.5 Building Height

Building heights shall be one to four stories, with maxi-mum building height to be consistent with the CDO (Cam-pus Development Overlay District) Zoning Ordinance of the Grafton Zoning By-law.

4.6 Building Materials and Palette

The primary exterior finish materials on all buildings shall be brick or stone masonry of a scale, color and finish similar to the brick and stone masonry used at the Tufts Cummings School campus. An exterior color rendering and exterior material finish board shall be submitted for Group review as part of the Final Plans and Specifications Submit-tal. The following criteria shall be used in the evaluation:

• The brick, stone, masonry and mortar shall consist of colors that visually recede into the landscape (e.g., non-reflective earth tones of red and brown).

• The contrast between brick, stone and mortar colors shall be moderate to low.

• The brick and mortar colors and textures shall be similar to those used on Cummings School campus buildings.

Secondary exterior finish materials (including, but not limited to window glazing, window and doorframes, roof coping and caulking) shall be evaluated. The following criteria will govern the evaluation of secondary materials:

• Glazing for doors and windows shall be non-reflective• Window frames, doorframes, roof coping and caulking

shall be complementary in hue and intensity with the primary building materials.

5.3 Service Areas

Adequate loading and maneuvering space shall be provided for each use, separated from the parking areas. All exterior service loading, storage, and utility areas shall be located at the rear or side of the buildings and will be screened or sheltered so as to minimize visibility from the street rights of way or from adjacent parcels. Refuse dumpsters will be located in these service areas and shall be screened with fencing or planting in accordance with Section 8.2.6 below. No other material supplies or equipment shall be permitted to remain outside any building without appropriate screen-ing.

5.4 Drainage and Erosion Control

Soil erosion and sediment control measures shall be in-corporated into the site design of individual development parcels in order to minimize erosion, off-site sedimentation and water quality degradation. These mitigation measures, which include construction techniques and design elements, should conform to storm drainage design and mitigation measures described the approved master plan and environ-mental impact report.

6. Lighting

Lighting shall be placed in a logical and appropriate rela-tionship to the site, not only to illuminate but also to pro-vide security. The Developer shall provide lighting in areas that receive heavy pedestrian and vehicular use, and in areas that are dangerous if unlit, such as stairs and ramps, intersections, or abrupt changes in grade.

Prevention of light pollution shall also be considered in the site lighting design, by utilizing semi-cutoff and full cutoff light fixtures.

Consistent use of standard science park light fixtures shall be used to visually unify the development.

The guidelines below are intended to ensure compatibili-ty between lighting schemes for the park, the Cummings School and the lighting along Westboro Road.

6.1 Pedestrian Walkways

Lighting for pedestrian walkways shall be mercury vapor or metal halide from a semi-concealed or visible source.

The lights shall be located either at ground level or on dark colored poles of 12-foot maximum height. Fixtures shall be spaced at intervals that permit a minimum light level of 0.5-foot candles between fixtures. The fixture shall be compatible with that specified for roadway and intersection lighting below. Special decorative fixtures may be used at entry plazas and patios where a special design character is desired.

6.2 Building Exterior

The lighting of building exteriors will not be permitted. There will be no up lit buildings and no lighting off of the buildings except at the loading dock.

Figure 14:

6.3 Parking Lot and Service Areas

Lighting for parking lot and service areas not lighted in Section 6.2 above shall be mercury vapor or metal halide. The fixture shall match or complement those specified for roadway and intersection lighting below. They shall be set on dark poles, 25 feet high. Fixtures shall be spaced at intervals that permit a minimum light level of 0.5-foot candles between fixtures.

6.4 Roadways and Intersections

Lighting for roadways and intersections shall be mercury vapor or metal halide from a concealed source. The fixture shall be set 25 feet high on dark poles. Minimum light level between fixtures shall be 0.5-foot candles. Along public or planned public roadways and at intersections, lighting must be consistent with the requirements of the Subdivision Regulations Section 4.7.5

14

7. Signage

All signs and graphic symbols shall conform to the Grafton Zoning By-law and the standards set forth herein.

7.1 Signs at Entrance

One identification sign containing the building address and tenant names may be erected at the entrance to each parcel at a location deemed to be suitably visible and appropriate by review of the Board. The entrance identification sign shall be fabricated with durable, weather-protected materi-als and finishes, in accordance with the criteria in Section 9.6.4.3 of the Zoning bylaw. Recommended are:

• Posts: Tubular steel or anodized aluminum in square cross-section, not to exceed six inches by six inches.

• Panels: Steel or anodized aluminum rectangular face, bracketed by the posts. The panel shall provide for the back lighting of letters.

• Finish color and lettering styles for the signs shall be consistent with the graphic image to be established by the Developer.

7.2 Signs on Building Exteriors

Signs will be permitted on the exterior of buildings in ac-cordance with Grafton Zoning Bylaw Section 9.6.4.3.

15

8. Planting

8.1 Intent

The tree cover of the Grafton Science Park site is one of the primary physical features contributing to its park-like character. It is valuable in establishing a compartmentaliza-tion of the site into a number of separate spaces and serves to partially conceal existing campus buildings. It will also partially conceal proposed buildings, and assist in main-taining a human scale of space between buildings.

Site vegetation should be preserved and enhanced, to retain the unified character of the site, and to compartmentalize space and screen built form to create a humanly scaled setting.

8.2 Design Guidelines and Criteria for Planting

8.2.1 Tree Preservation and Protection

To the maximum extent feasible, mature or healthy trees in wooded areas should be preserved and protected from damage during construction. With Board approval, site improvements are permitted within these wooded areas. These site improvements include pedestrian paths, pedestri-an lighting, site furnishings such as benches, picnic tables and trash receptacles; planting, seeding and sodding; and improvements to existing roads and paths.

8.2.2 New Planting

In general, new planting shall be of a type and arrange-ment that replicates the dominant existing tree and lawn landscape of the site. All unbuilt areas shall be landscaped with a combination of trees, shrubs, herbaceous perennials, and turf grass in accordance with the new planting zone guidelines below.

Figure 15: N ew Planting Layout for Parking and RoadwaysFigure 15: New Planting Layout for Parking and Roadways

16

8.2.3 Area A: New Planting for Road and Driveways

Roadside planting for the site’s main access road and for new interior project roads shall consist of deciduous shade trees. Depending on existing adjacent vegetation, these plantings shall be in either regular linear rows or informal groupings. Regular rows shall be used in cases where the road abuts an open area without existing trees or where one side of the road already has existing regular rows. Infor-mal groupings may be used where the road abuts existing informal groupings of trees. With either roads or informal plantings, trees shall be a minimum of a 3.5-inch caliper and planted in numbers equivalent to one tree per 40-linear feet of road edge. (See also Subdivision Regulations Sec-tion 4.5.1). Surface treatment for all unpaved road edges shall be turf grass.

Planting along driveways on individual development par-cels shall follow the same guidelines as above for project roads; however, the developer shall have the choice of either a regular or informal pattern.

8.2.4 Area B: New Planting for Parking Lots

Parking areas shall include pavement, islands, and sur-rounding edges to a depth of 15 feet, except in those edges between parking lots and buildings. Parking lot islands shall be provided between terraced parking levels and the ends of rows of parking spaces. They shall be a minimum of 10 feet from curb to curb. The Developer shall provide a minimum of one tree per five cars in parking areas. Trees may be planted in regular rows or informal groupings as space permits. The minimum distance from tree to curb shall be five feet in islands, five feet where the curb is adjacent to a building, and eight feet at all other parking lot edges. Minimum tree size shall be a three-inch caliper. Where parking lots abut a public road, shrubs shall also screen the lot. Screening shall be sufficient to effectively screen parked cars as seen from the public road. Surface treatment for all unpaved parking lot islands and edges shall be turf grass.

8.2.5 Area C: New Planting for Building Edges and Entrances

Planting for the spaces between buildings and parking lots and at building entrances shall be selected and arranged with the intent of creating human scale outdoor spaces, which recognize pedestrian activity in this zone and the need to identify building entrances. A full range of ground-covers, shrubs, and trees may be used in this zone to create interest and a degree of landscape detail appropriate to the pedestrian scale. All unpaved surfaces not planted with trees, shrubs, or groundcovers shall be turf grass.

Figure 16: I llustrative Planting at Area B - Parking LotsFigure 16: Illustrative Planting at Area B - Parking Lots

17

8.2.6 Area D: New Planting for Service Areas

All building service areas shall be screened with plantings. Screening shall be sufficient to conceal the service area ac-tivity from off-site view. At installation, the screening shall be effective to a height of four feet. At maturity, the plant screen shall be effective to a minimum height of eight feet.

8.2.7 Area E: New Planting for Edges of Development Abutting Natural Areas

Plantings shall be provided to blend the development edges with the abutting naturalistic areas, to provide not only aesthetic backdrop but also add biodiversity and habitat value. Recommended plants for these areas are native trees, shrubs, and groundcovers that are appropriate to the soil and hydrological conditions of the specific plating site. Special consideration shall be given to areas where the development abuts existing wetland areas and buffers.
