Whether or not a project comes within the purview of the MEPA review requirements, the BRA may request all or several of the environmental analyses listed below. The extent of analyses required depends on the size, location, and complexity of the project as defined in the scoping determination issued during Article 80 review.
[Article 80 Scoping. Large Project Review applies to virtually all major projects in Boston, usually defined as projects that add at least 50,000 square feet of gross floor area or rehabilitate at least 100,000 square feet of gross floor area. Through Large Project Review, the BRA, guided by comments from the public, examines a project’s impacts on its immediate surroundings and the city as a whole. Depending on the project’s size, location, and use, the review may address the project’s impacts in a variety of areas, including traffic and parking, environmental protection (wind, shadow, noise, etc.), the design character of the area, historic buildings, infrastructure systems (water, sewer, etc.), and employment. Based on the outcome of the review, the BRA may require the developer to modify the project’s size, mass, or design or take other measures to mitigate anticipated impacts.]

a. Shadow analysis may be required for existing (no-build) and build conditions for the hours of 9:00 a.m., 12:00 noon, and 3:00 p.m. for the vernal equinox, summer solstice, autumnal equinox, and winter solstice and for 6:00 p.m. in the summer and fall. In addition, on a case-by-case basis, analysis for other times of day (e.g., 10:00 a.m.) may be required
b. Shadow analysis shall be conducted using the Sun Altitude/Azimuth Table (see Appendix 6)
c. The shadow impact analysis must include net new shadows as well as existing shadows; net new shadows shall have a clear graphic distinction. For purposed of clarity, new shadows should be shown in a dark, contrasting tone distinguishable from existing shadows
d. Shadow analysis must show the incremental effects of the proposed development on existing and proposed public open spaces and pedestrian areas (including transit stops), including, but not limited to, sidewalks and pedestrian walkways adjacent to and in the vicinity of the proposed project and parks, plazas, and other open space areas. The analysis must clearly label all streets, vehicular paths, public open spaces, and pedestrian areas adjacent to and in the vicinity of the proposed project area. A North arrow shall be provided on all figures.
e. Additional shadow analysis may be required depending on the particular circumstances or physical characteristics of the project site,
