Home Browse Search

To the west of Bristol Street, between Memory Lane and Santiago Creek, is an additional area subject overflow from the Santa Ana River; however, Bristol Street in this area is sufficiently elevated allowing avoidance of this potential hazard. Surface drainage aiong Bristol Street flows in a southerly direction, intercepted by catch basins at various locations along the street. It is anticipated that the existing drainage system pattern will not be changed due to the widening of Bristol Street. Therefore, the storm drain improvements will be limited to reconstructing new catch basins at existing locations and any new catch basins as required to eliminate cross gutters at major intersections, 5. Vegetation and Biotic Resources During early consultation efforts for the preparation of this document, contact was made with the U.S. Fish and Wildlife Service, Laguna Nigel Field Office, to determine the presence or absence of any federally listed rare or endangered species within the project area. In a letter dated November 7, 1985, they indicated that no such species were known to exist here (see page IX -30). Since so much time has passed since then, telephone contact was made with the same U.S. Fish and Wildlife Service field office on December 6, 1989. Mr. Jack Fancher of that office confirmed that there are still no known rare or endangered species in the project area, The study area does not contain any indigenous vegetation whatsoever and does not provide a meaningful habitat for any faunal species. Vegetation present consists of urban landscaping limited to lawns, street trees and ornamental plants and shrubs typical of a suburban neighborhood. Landscaped areas along Bristol Street are generally confined to residential yards, perimeter landscaping in some commercial centers, and the grounds adjacent to some public and institutional facilities. Due to the age of most development adjacent to the street, the landscape vegetation in the area is generally quite mature and, thus, many species have attained a large size. The quality of landscaping and level of maintenance deteriorate noticeably moving southerly along Bristol Street as the age of development generally increases and the integrity of former residential districts breaks down due to the encroachment of commercial uses. Landscaping in the public right -of- way is limited to intermittent plantings of street trees, most commonly consisting of queen palm trees which have been reoccurringly planted along the entire length of the street. 1 ' 75C -80
