V. ADDITIONAL REGIONAL STAFF REVIEW ITEMS
The facility has not been constructed. However, it was noted in a 2014 staff report that a pond had been
constructed on this parcel after the issuance of the permit. From the Orange County GIS website it appears
that the pond was constructed sometime around 2007. Based off the submitted engineering drawings,that
RRO has,the permitted drip field is in the southeastern comer of the property. It is unclear if the pond
setbacks will encroach on the permitted drip area. It is suggested that before the construction of the facility
that all setbacks be confirmed to ensure compliance. Modification of the permitted drip area may be
required tprennssuree c�opiplli�ge tlr requi ed sgtbackss.Sp�ge;ted th a permit condition be added to verify
setbacks. ff FF ''JJ11 P a"0yl fro b ^`aJM"IeieUll��n��,
