Dave,
This plan (WPO201500066) is approved. This plan serves as an alternative to the prior approved plan,
WPO201400071. I believe that plan is bonded, and in that case can serve for this alternative also.
Please let me know if I can do something further to help.

Hi Glenn,
Were you able to find the plans we submitted last week? Can we expect a response today?
I greatly appreciate your attention.

Subject: Block 12 pond design
Hi Mark, Doug & Glenn;
On Tuesday we re -submitted the plan to Glenn Brooks for the block 12 pond. The revisions are a modification to our
plan that reflect input from County Engineering, Stantec and RGA to achieve what we hope you will meet both the
County's objectives and to keep us on track for the forthcoming master plan. This plan reflects:
Back slope of dam reduced to 2.5:1 (very near the 3:1 Glenn Desired)
• Inclusion of a Weir wall at the forebay instead of earthen dam. The added expense of this Weir wall helped
lower the dam and permanent pool elevation (achieving Glenn's desires to lower the pond below Old Trail
Drive).
• We contained and passed the 100 year storm thru the pond riser and eliminate the need for a rip -rap or
concrete emergency spillway providing more accurate measurement of flow (achieving one of Glenn's objectives
to both move away and lower this spillway from Old Trail Drive).
• Maintained 65% removal rate (which is in excess of the 50% normally required removal rate).
• Incorporated appropriate 10/10 2/2 storm criteria (a change back to more reasonable criteria that should have
been stated previously).
This pond design has come at an incredible expense to Old Trail Village. It has lasted over 18 months; included a costly
challenge from Engineering to our grandfathering rights that should never been an issue; significantly increased cost and
delays to completing a storm water master plan; added cost for two engineering firms to complete the work of one;
created tension from a changing design criteria through the submittal process; caused financial harm to our builders;
and is frustrating our homeowner who are unable to move into their homes.
I appreciate your effort to expedite the permit approval and bond posting as quickly as possible, so we can get back to
developing the real estate.
Regards,
David Brockman
