The pond was <br />installed in 1979 and included a combination primary and <br />emergency spillway. The pond does not match the proposed <br />dimensions, but does exceed the design volumes. The attached <br />diagram shows the plan view of the pond below the emergency <br />spillway and shows the volumes of the pond.

A 6" PVC primary spillway was installed with an 18" <br />P.,DS plastic oil skimmer/trash rack at that time. <br />..,~`N <br />N I. <br />~ !~ <br />~Qy Sr, •• <br />3 '~'` <br />~~ lk~'S9ti ,c'~ L c <br />m,~ ~,~~ <br />;, <br />q~ ~(`e.~ <br />~ yAdir-_~= <br />N.a.. ~..-~'r <br />
