A. Is there any indication from historical reconis that sediment transport (including scour <br />and deposition) ean affect the lOO-year waw.r-sw-ll'aee elevations,? <br />DYes [2] No <br /> <br />B. Based on the conditions (such as geomorphology,. vegetative cov.er and development of <br />the watershed and atream bed, and bank conditions), is there a potential for debris and <br />sediment transport (including scour and depoaition) to affect th.. 100-year water-surface <br />elevlltions and/or conveyance capacity through the bridge/culvert? <br />DYes IKI No <br /> <br />2.
