Thia ditch# if cenatructed# would 1 feel# result in the less of several large trees easterly of the proposed house location in the right-of-way of Pemdale Road. A ditch# if conatrueted# would naceasitate tha installation of two cttlvertsi one each under the existing driveway and the proposed driveway. Thaae consequancea of conatructing tha ditch as proposed# lead sm to baliava that this is not the proper solution to this drainage problem• ». ••• .> M h- ■ -.•*» ? K ’ •‘r ; • /.• ••. i - • .«• r- - ^ I would reeessMnd that tha owner be dirseted to retain the low area along Pamdala Road and his north«pasterly property line in ita natural state and to conatruct a flat drainage swale between the two elm trees (to the west of the proposed house) and tha westerly property line. This ditch should have a bottom elevation of 933«. Under this proposal# the minimal amount of water normally entering this drainage «ray trould be percolated into the soil# thereby creating no direct run-off to tha lake. In the event of •1 large rainfall# however# the swale would allow the water which is backed up# to overflow into the lake. If these roeoaBwndations are followed# the low area will function very much aa it does preaently# in that the overflow to the lake at present# occurs when the water reaches 933 elevation. This occurs after the pocketing of water to a depth of roughly S inches. Since the water would not be retained to a lavel higher than is presently the ease# the adjoining property owner to the west should have no cause for alarm.* ■Wfc. t alarm.” ■ x;...
