Walls The Environmental Impact Statement requires the placement of sound absorbing walls that are at least six -feet high on the rear edge of the parcels abutting residential areas. The layout guidelines for the walls as described in the Bristol Street Widening Project should be maintained, with additional considerations as follows: • The walls should be divided in three sections: straight runs, ornamental runs, and end runs. The purpose is to adjust the design of the walls according to their proximity to pedestrian activity, which increases towards the side streets. c The "straight runs" occupy the mid -sections of the wall between street intersections. These runs should be plain and simple, constructed of a single material and without excessive ornamentation. The walls should be planted with vines to eliminate the opportunity for graffiti and to soften the wall and add to 'green environment'. o The "ornamental runs" extend 100 feet from a side street right-of-way, and, owing to their proximity to pedestrian activity, should offer more visual interest. Espalier vines, colorful tiles, decorative caps and piers should be considered as integral elements of the wall. o The "end run" corresponds to the terminal sections of the wall as they meet side streets. These sections should be "opened -up" or perforated, allowing for wrought iron or other see -through ornamentation, including shrubbery, to soften their appearance as they meet the side streets. The length of the "end runs" should match adjacent building setbacks or be about 20 feet in length, whichever is greater. The wall ends should also act as "gateways" into the residential areas. Pylons, posts, trellises or other similar features should be considered, possibly incorporating neighborhood identification signs and logos. The "end runs" should be designed in pairs -two per side -street - with each pair assuming a distinctive character Figure 5-13 depicts the above concepts. Figure 5-14 and Figure 5-15 depict the treatment at the end of cul-de-sac streets. Architectural Character The commercial sites within the corridor are for the most part small in area and therefore will be occupied by moderately sized retail or office buildings. Following the land use concept, these buildings will be spaced along the corridor rather than grouped to form long, "hard" edges; they will appear more like "structures in a park" than as a continuous urban frontage, For this reason, the buildings should be designed so that all of their visible sides display a reasonable architectural interest and fagade articulation. Exposed, blank walls should be avoided. The emphasis should be on breaking the regularity of buildings, on treating them like ornaments in the landscape, with as much fagade interest and articulation as possible within the limits of feasibility. On long buildings (over 50 feet in length), roof lines should be continuous but interrupted, either by breaks in the roof lines or by wall extensions or parapets; smaller buildings should be treated like pavilions, with continuous parapet ornamentation or sloped roofs on all side. In all cases, buildings should blend with the landscape Bristol Street Corridor Specific Plan March 2018 and the surrounding homes and businesses. Colors should be soft and muted rather than bright and contrasting. An emphasis on high quality design, materials and architecture is recommended, with additional guidance available through use of the City of Santa Ana's Design Guidelines and Development Standards. However, in as much as the Specific Plan dictates a specific approach to the corridor's architecture, it must not preclude variety and/or refinements to the design intent. In this vein, the design guidelines are purposefully wide in scope, focusing not on the detail of the buildings but rather on the broad issues of scale, massing and facade articulation. They thus guard against possible gross misinterpretation of the stated aesthetic objectives while leaving ample room for creative and ingenious solutions. Page 151
