4.03–G Definitions. Terms specific to this section are defined as follows:
Frontage Buildout. Frontage buildout shall be calculated based on the widest point of a building between the minimum and maximum front setback lines and the width of the lot at the front lot line.
4.03–H Maintenance Structures
(1) Maintenance Structures, as defined herein, may exist as the sole structure on a lot without meeting the street dimensional and architectural standards that would otherwise apply to principal structures.
(2) Maintenance structures shall be clearly intended to service a recreational amenity or serve as a maintenance storage function on the site.

Table 4-2. A Street Dimensional Standards
A Streets are lined with mixed-use, multi-story storefront buildings that are positioned at the front of each lot. The following standards shall apply to all lots and buildings fronting on an A Street:
1. Setbacks are provided accordingly:
a. 10 feet per additional story over two stories, never to exceed 50 feet from the road right of way.
2. The space within the front setback must be programmed as follows:
a. No parking shall be permitted.
b. No access drives shall be permitted in front of the building unless as a circulation lane required by Town Emergency service directors in consultation with the Director of Planning and Zoning.
c. The space shall serve as a civic amenity for the adjacent buildings and shall be thoughtfully landscaped. The space shall be open and usable to the tenants of the adjacent buildings and shall be attractive, welcoming and inviting. Additional, low-height street trees are encouraged.
d. Year-round, fixed seating shall be provided.
e. The area may be used for outdoor space for the ground-floor non-residential spaces, including café seating and limited, organized retail display areas which do not impede pedestrian movements.
3. The Development Review Board has the ability to grant additional setbacks, with the minimum reasonable relief, where there is substantiated confidence that a near-term future widening of the right-of-way on these named roads will cause reduced setback once built.
