2 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 .

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 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 Campus Design buildings to reflect the character, color, and texture of the historic buildings on the Grafton campus. • Avoid Impacts to Sensitive Environmental Resource Areas Locate 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 Safety Maximize 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.

These Building locations are illustrated To the extent practicable, the Developer should employ in Figure 3 (Spagnolo/Gisness Conceptual Plan, September new building “green” design principles and follow LEED 2005). Holdings prefers that the building envelopes be the standards. The Developer should promote sustainability by only areas within which building development shall take increasing energy efficiency and using renewable resourc- place. However, the square footage of development assign- es, as well as reducing greenhouse gas emissions and other able to each envelope will be a function of market demand, waste and hazardous material production. 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.

It will also and turf grass in accordance with the new planting zone partially conceal proposed buildings, and assist in main- guidelines below. 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.

Depending on existing adjacent vegetation, these and at building entrances shall be selected and arranged plantings shall be in either regular linear rows or informal with the intent of creating human scale outdoor spaces, groupings. Regular rows shall be used in cases where the which recognize pedestrian activity in this zone and the road abuts an open area without existing trees or where one need to identify building entrances. A full range of ground- side of the road already has existing regular rows. Infor- covers, shrubs, and trees may be used in this zone to create mal groupings may be used where the road abuts existing interest and a degree of landscape detail appropriate to the informal groupings of trees. With either roads or informal pedestrian scale. All unpaved surfaces not planted with plantings, trees shall be a minimum of a 3.5-inch caliper trees, shrubs, or groundcovers shall be turf grass. 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.
