Olivia,
I have reviewed As -built grading certificates submitted for Lots 5 and 6. The As -built certificates are
in conformance with the approved certificates of survey.
I did visit the site to visually verify, to the extent possible, the drainage patterns. The main issue that
needs to be addressed is located along the south side of Lot 6 as shown on the attached pdf. The
clouded area shown generally indicates the location where the yard was very wet the day I visited
(Wednesday of this week). It is my understanding in speaking with others that it is has been typically
wet in that area.
It was clear from the original grading plan and now is confirmed by observing the constructed
conditions, that the correct grading of Lots 4 and 7 is particularly critical to ensuring that Lots 5 and 6
drain properly.
Let me know if you have any questions.
