(b) The following design standards shall apply to new construction and to additions to existing structures. Except as otherwise provided, an existing building that is altered or moved to accommodate an AHO Project shall not be subject to the following standards, provided that such alterations do not create a condition that is in greater nonconformance with such standards than the existing condition. 11.207.7.2 Site Design and Arrangement (a) The area directly between the front lot line and the principal wall plane of the building nearest to the front lot line shall consist of any combination of landscaped area, hardscaped area accessible to pedestrians and bicyclists,

and usable spaces such as uncovered porches, patios, or balconies.

Such projecting or recessed elements shall not be required on the lowest Story Above Grade or on the highest Story Above Grade, and shall not be required on the highest two Stories Above Grade of a building containing at least six Stories Above Grade. The intent is to incorporate elements such as bays, balconies, cornices, shading devices, or similar architectural elements that promote visual interest and residential character, and to allow variation at the ground floor and on upper floors where a different architectural treatment may be preferable. 11.207.7.4 Ground Stories and Stories Below Grade

(e) Ground Stories shall be designed to accommodate at least one space, with a total frontage equaling at least fifty percent (50%) of the existing retail frontage, for an active non-residential use, which may include retail or consumer establishments as well as social service facilities supporting the mission of the owner of the AHO Project, on sites that are located in a Business base zoning district, and where the project site contains or has contained a retail and or consumer service use at any point within the past two years prior to application for a building permit for an AHO Project. (f) Private living spaces within dwelling units, including bedrooms, kitchens, and bathrooms, may only be contained within Stories Above Grade. Stories Below Grade may only contain portions of dwelling units providing entries, exits, or mechanical equipment, or common facilities for residents of the building, such as lobbies, recreation rooms, laundry, storage, parking, bicycle parking, or mechanical equipment 11.207.7.5 Mechanical Equipment, Refuse Storage, and Loading Areas (a) All mechanical equipment, refuse storage, or loading areas serving the building or its occupants that are (1) carried above the roof, (2) located at the exterior building wall or (3) located outside the building, shall meet the requirements listed below. Mechanical equipment includes, but is not limited to, ventilation equipment including exhaust fans and ducts, air conditioning equipment, elevator bulkheads, heat exchangers, transformers and any other equipment that, when in operation, potentially creates a noise detectable off the lot. The equipment and other facilities: (a) Shall not be located within any required setback. This Paragraph (a) shall not apply to electrical equipment whose location is mandated by a recognized public utility, provided that project plans submitted for review by the City identify a preferred location for such equipment.

The screening shall consist of a dense year-round screen equal or greater in height at the time of installation than the equipment or facilities to be screened, or a fence of equal or greater

height that is comparable in quality to the materials used on the principal facades of the building, with no more than twenty-five (25) percent of the face of the fence open with adjacent planting. (c) When carried above the roof, shall be set back from the principal wall plane by a dimension equal to at least the height of the equipment and permanently screened from view, from the ground, from adjacent public streets and any abutting residentially used lot or lots in a residential zoning district. The screening shall be at least seventy-five percent (75%) opaque and uniformly distributed across the screening surface, or opaque to the maximum extent permissible if other applicable laws, codes, or regulations mandate greater openness.

(c) An AHO Project shall be subject to other applicable laws, regulations, codes, and ordinances pertaining to environmental standards. (d) New outdoor light fixtures installed in an AHO Project shall be fully shielded and directed to prevent light trespass onto adjacent residential lots. 11.207.8 Advisory Design Consultation Procedure Prior to application for a building permit, the developer of an AHO Project shall comply with the following procedure, which is intended to provide an opportunity for non-binding community and staff input into the design of the project.

(a) The intent of this non-binding review process is to advance the City’s desired outcomes for the form and character of AHO Projects. To promote the City’s goal of creating more affordable housing units, AHO Projects are permitted to have a greater height, scale, and density than other developments permitted by the zoning for a given district. This procedure is intended to promote design outcomes that are compatible with the existing neighborhood context or with the City’s future planning objectives for the area. (b) The City’s “Design Guidelines for Affordable Housing Overlay,” along with other design objectives and guidelines established for the part of the city in which the AHO Project is located, are intended to inform the design of AHO Projects and to guide the Planning Board’s consultation and report as set forth below. It is intended that designers of AHO Projects, City staff, the Planning Board, and the general public will be open to creative variations from any detailed provisions set forth in such objectives and guidelines as long as the core values expressed are being served.
