Interoffice memorandum Walker to Brown 29 June 1999 Page 2 of 6 Pages CHECKLIST FOR SEDIMENTATION POND AS-BUILTS This is a checklist of required and preferred items to be on a sedimentation pond as-built. Technically, an as-built is a representation of all physical features of the structure. Horizontal features of size and configuration (including contour lines) aze shown on a plan view. Vertical aspects aze often, and better, shown on cross-sections or profile drawings. Text specifications often appear on an as-built. Operational features of a pond aze required to demonstrate compliance with the Rules, and these items are best illustrated (operational design requirements) on an as-built drawing. As-builts should confirm that a structure is built according to an approved design. Designs are based on studies, investigations, and demonstrations, and need to demonstrate general compliance with Rule 2.05.6(3). Required design aspects that do not appeaz on an as-built need to be presented elsewhere in the Permit. Inclusion on the as-built often eliminates duplication of information in the Permit by presentation of design, as well as as-built, features on a single drawing. As a matter of practicality, as-built drawings are frequently annotated design drawings. Pond # _015 ,Permit C-_81_ _057_, date:_29 Jun 1999 ITEM REFERENCE PURPOSE COMPLIANCE?
