(District II) [CDD-CP# 06-26] Project No. 0672-686115 DATE: April 11, 2006 PAGE: 2 of 2 FISCAL IMPACT: The project will not impact the General Fund. It will cost approximately $60;000, which will come from Road fluids. REASONS FOR RECOMMENDATIONS AND BACKGROUND: The project consists of re-constructing a failed wing wall which was attached to an existing bridge abutment at 5085 Alhambra Valley Road. The abutment is located downstream of a box culvert that conveys Arroyo Del Hambre Creek under Alhambra Valley Road. The.-new wing wall will tie into the same location of the failed wall, and will continue approximately 12 feet farther along the creek bed,tying into the embankment.Interlocking concrete blocks will be used for the construction(2.5 ft W X 5.0 ft L X 2.5 ft H)to a height of approximately 12 feet. The total length of the repair will be approximately 21 feet. Some excavation will be necessary for building the foundation,which will be built at the same level as the bridge footing,and will be approximately 2.5 ft deep X 5 ft. wide. A minor amount of rock slope protection will be used on the downstream end of the construction to prevent a washout in this location.Minor traffic regulation will'take place to direct equipment to and from the construction site.Flaggers will be used for this purpose to ensure that impacts to traffic are minimized.A dewatering system will be used during construction.The system will be designed to ensure that flow downstream of the construction is maintained at all times during construction. It can be seen with certainty that there is no possibility that the activity may have a significant adverse effect on the environment.. CONSEQUENCES OF NEGATIVE ACTION: Failure to approve the CEQA document will delay the needed repairs and may allow additional damage to occur at the County road facilities.
