At that time, profile work sheets for Cedar Creek and <br />Montrose Arroyo with the lOO-year floodplain work maps for <br />Cedar Creek were submitted for review, The Dry Cedar Creek <br />profiles and flooded area maps and a complete set of maps for <br />,Montrose ..Arroyo were subsequently received on November 2, 1978. <br />Revised summary computer printouts and other material fOr reaches <br />re-analyzed due to initialization revisions were received on <br />November 16, 1978. <br /> <br />A. <br />contract <br />to date: <br /> <br />In comparing the Hydraulic ~~echnical Addendum 1.i th <br />specifications, the followinsr deficiencies are noted <br /> <br />he <br /> <br />Ti~.;. <br /> <br />P.L:; ...i.li,;/, <7.,> <br />1.

At th~ <br />conclusion of the project, please submit an album of all origfLnal <br />photos or negatives.
