ILL <br /> <br />Memorandum <br /> <br />DATE: Mamh 31, lgg7 <br /> <br />TO: Stew Little <br />FROM: Bitt Co~hmn <br /> <br />RE: Darns It Laka Co~¢ord & Frank Nske Park <br /> <br />CC: Tim Lowder, PE <br /> <br />Frank C. Cocldnor,, PE <br /> <br />LAK~ CONCO~O <br /> <br />As you Ire aware ~ am tw~ major concerns at Lake Cor,;ord. The rmopaOo along the toe of <br />the clam must be collected In a drainage flekl alld the broken areas of the lower poRIon of the <br />spillway must be repaired. <br /> <br />I have ~mtacted, an engineering firm in ~, N. C. to asrdst me with the engineering on the <br />project On Mamh 19, lg97 BoMoomftekl (FrankC.

We are In agree'met ~ to the <br />proper approach requlrad to resolve the ~aage pmlNem. Several ldea~ wine e~ <br />regardk~g the repair to the extended spillway, va~ng from d~ng no~lng to a compk~ new <br />concrete IAmctum. We were able to c<~vlnce the Dam SM1Ry er~llneem th~ tt~ Im~illal~ cd <br />a toewall at the end o! the eM~lded spillway shou}d suffme for many ~ara. This will be an <br />expenr~ive job, but it isthe mo~t l~omlcal method. In addition to Ut]l ~ EWIll b/ <br />necasr.~y to bmek up the large pieces of broken ¢Ollcmte0 Idd moI~ Iai'ge Up-rap and di~ltlxlte <br />this broken concta~ and tip-rap around the Ipllllng bi.in ama in ruder to dlio~ the ~ ~ <br />downstream. <br /> <br />The ~ cosl for the ..r~, ~o11~, ~a'uctuml and cml m~linee~ing ~ inotuding <br />Inr~ Is $9,S00.00. <br /> <br />U,~I the Itudlel are complete It h~ Impolalbte to ~ you with In Iccurate col~ll't~-'Iio~ <br /> <br />repair requirements. I beliew that II rea~c~abte figure for the repaJm at Lake Concord will be <br />$00.500 plus the survey and engineering.
