Keith,
Could you open the attached pdf file of Windsor Estate drainage sheet and the Deforest Court
give me a call
drainage sheetthen at yourconvenience?
I cannotfigureout what the consultant did between theWindsor Estatesprojectand the second
project Deforest Court with the drainage calculations and the starting HG. Also, it appears to me that
the consultant did not includethe drainage area fromVillages of Coppell Phase 3 “DA area H” and
Villages of Coppell Phase4 “DA areaD”.
My question to you is, does GSWW simply continue with the current36-inch RCP base upon the
existing design or do we need tore-calculate the detention and whole existing system that was just
built?
