15 SIDEWALK DESIGN LEVEL I SIDEWALK In this classification, the entire sidewalk is constructed of brick paving, in order to indicate its high level of pedestrian use. These sidewalks offer the highest level of pedestrian enhancement. This design is currently in place on the four blocks facing the Courthouse Square and along Main Street from 5th to 10th Streets. It should be continued along 8th Street from the courthouse to the new library and proposed Municipal Center festival street. KEY FEATURES Brick pavers laid in a herringbone bond Brick paver bands on both sides of central pavers, laid in a stack bond (use of both single and double bands of these accent bricks are seen) Concrete band (curb and gutter) on street side of pavers Tree and flower planters Decorative lights, benches and waste receptacles Level I sidewalk 13

16 LEVEL II SIDEWALK This sidewalk has a band of brick pavers at the outside edge of the walk. The remainder of the walk is finished concrete, scored in 2-foot square modules. This provides texture and interest in a more economical manner, and helps to distinguish these streets from those that are all brick. KEY FEATURES Modular pavers along the sidewalk edge, laid in a common bond Concrete bands (curb and gutter) on street side of pavers Tree and flower planters Decorative lights, benches and waste receptacles LEVEL III SIDEWALK In this classification, the sidewalk is constructed of scored concrete, in the 2-foot square module. Brick pavers would be used for accents, at special seating areas or corner landscape features. These sidewalks can either be installed detached from the street and separated by a landscaped planting strip or attached to the street with a concrete curb and gutter. Installation is dependent upon the existing streetscape character along the block. KEY FEATURES Scored concrete in 2-foot modules Decorative lights, benches and waste receptacles should be installed on the 7th Street route to Southwestern University, which is one route designated for this application. Level II sidewalk Level III sidewalk 14

17 TYPE A INTERSECTION TYPE B INTERSECTION Type A intersection In this classification, the intersection is constructed of decorative paving, in order to indicate its high level of pedestrian use. In some cases, the existing curb line and corner radius should be retained, but in some special conditions, bulb-outs at corners may be expanded to better delineate parking lanes and provide additional area for street furniture and plantings, similar to those around the square. This also increases visibility and decreases pedestrian crossing time, thereby improving pedestrian safety. The radius of the expanded corner should also be designed to facilitate turning for large delivery trucks. KEY FEATURES Decorative paver at corners Decorative paver in center of intersection Scored concrete crosswalks Pedestrian controlled crossing signals Type B intersection In this category, either decorative pavers or scored concrete is used within the sidewalk boundaries at corners. The crosswalk areas are defined by scored concrete. The paver treatment is dependent upon the type of sidewalk designation for the intersection and should be consistent. KEY FEATURES Decorative pavers at corners Scored concrete crosswalk Type B intersections include a band of pavers with scored concrete crossings. 15

18 TYPE C INTERSECTION Type C intersection In this category, scored concrete is used within the sidewalk boundaries at corners only, while the crosswalk areas are defined by conventional stripes. This level of intersection design is appropriate in areas of lower crossing conflict. TYPE D INTERSECTION In this category, intersections appear as conventionally designed. No upgrades or enhancements are necessary. INTERSECTION IMPLEMENTATION ACTIONS A series of intersections should be constructed at one time, as a set, such that one of the key pedestrian routes is completed. These may be financed as a part of the city s capital improvements program, or through a special improvement district. These techniques are described in the appendix. As an initial step, detailed designs must be developed, based on the conceptual sketches provided in the plan. KEY FEATURES Striped crosswalk Scored concrete corners Type C intersections include a striped crosswalk. 16
