i .�,. , z The existing channel is only approximately 2 feet wide as it crosses the subject property. Although the subject property is approximately 6 feet higher than the stream, the property immediately to the north is very near stream level and likely floods already. The adjacent homeowner may well claim that future flooding incidents are a result of the construction on the subject property. This makes it critical that the stream channel not be disturbed or filled in any manner. There are a couple of locations where this has appeared to have occurred already. The existing stream channel makes a 90 degree turn just as it enters the subject property. This is a location that will be highly susceptible to bank erosion. The bank erosion, if uncontrolled, may ultimately undermine the foundation. To alleviate these concerns any variance should be contingent upon the following conditions: 1. A filter fabric fence should be installed along the top of the stream bank. This will prevent silt from entering the stream I during construction and form a physical barrier to discourage any � construction activity (such as filling) within the stream channel. i � 2. Any loose fytll material along the stream bank should be removed. 3 . Grass sod should be staked in place along the stream bank �I following construction completion. 4 . Rip rap underlain by filter fabric should be placed along the . stream bank where the stream makes a ninety degree turn. 5. A hold harmless clause for future damage claims resulting from stream erosion or floo3ing should be executed and recorded.
