As a result the existing encroachment does not meet the mandatory 500' line of site visual clearance. There is only a 270 foot visual clearance at the present site. It therefore poses a very viable traffic hazard to both north and south bound travel on Centerville Road. Also the existing encroachment erodes directly into the historic pond, contaminating its water quality as seen by the extensive algae bloom since grading operation began. February 1998 pond before any grading February 2007 pond since grading Due to the inaccuracies listed above, we do not feel that the county can come to the conclusions reached in the Mitigated Negative Declaration. We propose that there is a significant Impact to all of the following: Aesthetics — degrading the natural setting of the canyon Biological Recourses — adverse effects to riparian habitat Cultural Recourses — disturbance to Indian artifacts Hydrology/Water Quality — Degradation I siltation of historic pond and Butte Creek Geologic Processes — substantial erosion of topsoil Transportation/Traffic — present encroachment poses substantial traffic hazard. Until these items are address, we challenge the approval of a grading permit.

As a result the existing encroachment does not meet the mandatory 500' line of site visual clearance. There is only a 270 foot visual clearance at the present site. It therefore poses a very viable traffic hazard to both north and south bound travel on Centerville Road. i Also the existing encroachment erodes directly into the historic pond, contaminating its water quality as seen by the extensive algae bloom since grading operation began. t all February 1998 pond before any grading February 2007 pond since grading Due to the inaccuracies listed above, we do not feet that the county can come to the conclusions reached in the Mitigated Negative Declaration. We propose that there is a significant Impact to all of the following: Aesthetics — degrading the natural setting of the canyon Biological Recourses — adverse effects to riparian habitat Cultural Recourses — disturbance to Indian artifacts Hydrology/Water Quality — Degradation / siltation of historic pond and Butte Creek Geologic Processes — substantial erosion of topsoil Transportation/Traffic — present encroachment poses substantial traffic hazard.

The option of other corrective measures will be considered; which may preclude future occurrences of a failure. Regarding the Second problem, materials that have washed down from previous corrective actions have made inoperable the culvert system that existed on the site (years prior to current grading work). The County has agreed to allow replacement of this culvert pipe. Upon completion of that installation, the sediment will be removed and clean straw bales will be secured to the ground, to provide adequate cleansing of the run-off.

Water channels are all flowing and seepage from surface areas is fairly heavy. Conditions are ideal for evaluating the effectiveness of the Storm Water Pollution Prevention Measures and previous corrective actions and repairs. • Erosion of the driveway is near the entrance to the site has been eliminated. • The Storm Water Pollution Prevention Plan and additional implemented solutions, are all functioning as intended, and quality of storm water leaving the site is good. Actions Taken: • Maintenance has been performed at the driveway entrance area to re -direct the run-off from the driveway surface and into the intended drainage swales. Straw bales have been replaced, and grading and compaction have been performed to stabilize the driveway.

As a result the existing encroachment does not meet the mandatory 500' line of site visual clearance. There is only a 270 foot visual clearance at the present site. It therefore poses a very viable traffic hazard to both north and south bound travel on Centerville Road. Also the existing encroachment erodes directly into the historic pond, contaminating its water quality as seen by the extensive algae bloom since grading operation began. February 1998 pond before any grading February 2007 pond since grading Due to the inaccuracies listed above, we do not feel that the county can come to the conclusions reached in the Mitigated Negative Declaration. We propose that there is a significant Impact to all of the following: Aesthetics — degrading the natural setting of the canyon Biological Recourses — adverse effects to riparian habitat Cultural Recourses — disturbance to Indian artifacts Hydrology/Water Quality — Degradation / siltation of historic pond and Butte Creek Geologic Processes —substantial erosion of topsoil Transportation/Traffic — present encroachment poses substantial traffic hazard.

M. GILBERT ENGINEERING adequate, however, unforeseen circumstances (straw bale plugging outfall) result in breeching the system. The option of other corrective measures will be considered; which may preclude future occurrences of a failure. Regarding the Second problem, materials that have washed down from previous corrective actions have made inoperable the culvert system that existed on the site (years prior to current grading work). The County has agreed to allow replacement of this culvert pipe. Upon completion of that installation, the sediment will be removed and clean straw bales will be secured to the ground, to provide adequate cleansing of the run-off.

Water channels are all flowing and seepage from surface areas is fairly heavy. Conditions are ideal for evaluating the effectiveness of the Storm Water Pollution Prevention Measures and previous corrective actions and repairs. • Erosion of the driveway is near the entrance to the site has been eliminated. • The Storm Water Pollution Prevention Plan and additional implemented solutions, are all functioning as intended, and quality of storm water leaving the site is good. Actions Taken: • Maintenance has been performed at the driveway entrance area to re -direct the run-off from the driveway surface and into the intended drainage swales. Straw bales have been replaced, and grading and compaction have been performed to stabilize the driveway. Photographs of SWPPP control measures: The following photographs, taken March 2, 2006, demonstrate the current conditions on the site: This was the condition at the Mitered End Section before corrective action. This is the corrective action completed at the Mitered End Section. Flow is adequate, after maintenance. 01)6- This )s I r�. ���f>rl 'rr 1_�i%jij,1� / i—may► '.� .+ � � _ 4 .. - J y�'P T�,�,. .� _ `I�iil] y '1�1.{'Y i.. �r � ... y„� • � t .y it � ~ Y inKp '0; { �',• 11 r l�f 4...a.t. , � "tyJ -><+ • .:'"jO�.?at }f"'1f4`P�� `�' '::�� �rt` �..t`�frfs �" � r," { L. l4 !. n"r�4^ r`� '� �,�"" fyn . 4 .• ,��,.r1Yd+�... �:�' �,.
