inches. As stated in Section 4.7.4. of the ESCS, the minimum orifice size is 0.5 inches due to
clogging concerns. Always be sure and download the latest version of WWHM2012, the
program has MANY bugs. The Clear Creek Solution has the latest free downloads available
(http://www.clearcreeksolutions.com/SearchResults.asp?Cat=17 ). While this website says

10. 5/28/15 Control Structure Detail – The riser is modeled as an 18 inch pipe, The detail shows 12
inch pipe, please reconcile. Also, this detail shows a shear gate which is in conflict with City of

(http://www.edmondswa.gov/engineering-standards/section-5-storm-drainage.html ).
The east inlet to the vault have a invert elevation of 397.0, only 1 foot above the bottom of the live
storage. The pipe also has a 10.71% slope. Making the inlet at a higher elevation would reduce
backup in the pipe.
The Flow Control Structure detail on Sheet C8.0 needs elevations for the office(s), top of the
riser and the notch match that the modeling so it can be constructed properly. Also, make
the notch a rectangular notch to match the modeling.
