The Owner required a bathhouse and than took the bathhouse out. We have advised him to include the proposed bathhouse in the permit. In addition the boat ramp area was used in the original calculations The ramp is not Included In the revised calculations. The numbers in the narrative have been corrected. The numbers on Sheet 2 of 4 of the application have also been modified 2 Please dar*en up the print on the basin calculations page where the contour elevation and area are shown The pnnting is a very light tan that is almost unreadable The onginat copy was red and pretty I guess you were reading a copy which was not so pretty. Anyways it has been changed per your request. 3 Vincent seems to remember that the proposed basin was located in an area that he thought was determined to be unsuitable for infrlfration He is willing to reschedule the site visit for early in the coming year to confirm, since the completed site investigation farm can not be found Based on Vincent's review and recommendations we raised the infiltration basins so that the inverts of the proposed infiltration basins are at existing grade Vincent Indicated that the first 2 feet of the soil strata were acceptable for use in an infiltration bed.
