Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. We evaluated options of sloping down the banks with matting and seeding but the eroded culvert side is too close to W. Friendly Avenue, a major thoroughfare. We determined best solution will be installing boulder toe wall to protect further erosion toward the road. Here is a list of the design options that we evaluated and the reasons why we considered them not feasible. 1. Do nothing — Not an option because of the road. 2. Layback stream bank —There is less space between the road and the stream bank. 3. Install boulder toe wall — This will encroach less space and stabilize bank. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Since the stream is wide (about twenty five feet) in this area we will be utilizing sand bags to divert flow from the work area to reduce impacts upstream and downstream of the construction. We will install a check dam just downstream of the construction to reduce the sediment flowing downstream. Sunset Hill Channel at W. Friendly Drive & W.
