Kevin Lindley, P.E. <br /> Staff Engineer <br /> Planning & Inspections Department <br /> Orange County <br /> 200 S. Cameron Street <br /> PO Box 8181 <br /> Hillsborough, NC 27278 <br /> Via email: klindley @orangecountync.gov <br /> Re: 2015 Inspection of Lake Orange Dam <br /> Dear Mr. Lindley: <br /> At your request, Hazen and Sawyer is pleased to submit this proposal to Orange County <br /> for professional engineering services to complete a reconnaissance-level inspection of <br /> Lake Orange Dam. The level of effort that we propose is consistent with our 2009 <br /> inspection. The purpose of the 2015 inspection is to make a general assessment of the <br /> condition of the dam and appurtenances based on a visual inspection and to identify any <br /> potential areas of concern that might warrant closer examination and/or remedial <br /> attention. <br /> The scope of service that we propose for this assignment is as follows- <br /> 1. The undersigned or other qualified engineer will complete what is expected to <br /> be a one (1) day reconnaissance-level inspection of the dam and <br /> appurtenances. <br /> 2. Physically inspect the dam embankment and abutment contact areas to identify <br /> any indicators of excess seepage or unusual embankment performance. As in <br /> the 2009 inspection, we would prefer to make this inspection soon after the <br /> embankment has been mowed to improve our opportunity for detecting any <br /> embankment deficiencies. Our inspection will include a visual assessment of <br /> the "bowls" that your contract mower has observed on the downstream dam <br /> slope. Although, we expect that these will be ready detectible in the field, to <br /> make sure that we do not miss any of these areas, we recommend that the <br /> mower flag the individual "bowls" and/or that you or another knowledgeable <br /> person from your office attend the inspection. <br /> 3. Physically inspect the intake structure and related equipment to identify any <br /> unusual conditions or areas of concern. <br />
