will be made to the existing Civic Park adjacent to the proposed parking lot to enhance the trail connectivity as is shown on the color renderings. Comparison to Firehouse Arts Center Corridor Improvements The proposed parking lot between Bernal Avenue and Abbie Street consists of a 56- foot-wide paved parking lot to accommodate 140 perpendicular parking stalls (8.5 feet x 17 feet spaces on the west side; 8.5 feet x 15 feet spaces on the east side), a 24-foot wide drive aisle, a varying width concrete path — with a width of eight feet at four pinch- points, and a landscaped area ranging from zero to five feet wide adjacent to the properties on the east and west sides. The Firehouse Arts Center parking lot consists of a 56-foot-wide paved parking lot to accommodate 91 perpendicular parking stalls (9 feet x 16 feet), a 24-foot, two-way drive aisle, an eight-foot-wide concrete pathway, a six-foot-wide decomposed granite multi- use trail, and landscaped areas and landscaping of varying widths between property lines throughout. While the improvements are similar in design, it is important to note the differences between the proposed corridor improvements between Bernal and Abbie and the Firehouse Arts Center corridor improvements. The transportation corridor at the Firehouse Arts Center is 25 feet wider than the 75-foot corridor width between Bernal Avenue and Abbie Street. While the parking lot dimensions as stated above are nearly identical, and both areas will include a concrete walkway with a minimum width of eight- feet, the additional 25 feet at the Firehouse Arts Center allows for a six-foot-wide multi- use trail and additional landscaping widths within the corridor. Although the FHAC includes both the concrete path and multi-use trail, it is also important to note the FHAC concrete path is only eight feet wide for the entire length of the corridor. The concrete path proposed as part of the current design varies in width from 10 feet (in Civic Center Park) to, generally, nine feet adjacent to the retaining wall, except where it pinches down to eight feet in four locations. How the Challenges Affected the Design 1. The proposed parking lot area is on the east side of the corridor, as compared to it being on the west side at the Firehouse Arts Center. This is because grading on the east side is limited by the Kinder Morgan high-pressure gas pipeline, and the mature trees and improvements that exist on the east side properties. 2. The grade change across the width of the corridor necessitates construction of a retaining wall along about half the length of the corridor. The retaining wall cannot be along the east edge because excavation over the Kinder Morgan line is not permitted. The wall cannot be along the west edge as the adjacent property owners do not desire to be separated from the corridor improvements with a retaining wall right on top of the property line. The retaining wall location was designed to be between the parking lot and the concrete path. This way, the grade change could be accommodated within the corridor and the private property edge conditions could remain relatively unchanged. Page 6 of 10
