Please <br />review Exhibits A & B. All ten undeveloped lots are confirmed as meeting <br />required standards. Of the total 20 test areas, 4 tested out as standard <br />systems and the remaining 16 as mound systems. If any members have <br />reservations concerning the use of mound design systems, please contact <br />Mike Gaffron prior to the meeting as he will not be present at the December <br />21st meeting. Staff can confirm that the only known failure of a mound <br />system was a result of faulty installation and had no bearing on the actual <br />design of the system. Standard systems fail when installed incorrectly <br />also. The average cost of installing a mound septic system runs anywhere <br />from $8,000-10,000 and a standard system $4,000-6,000. Review Exhibit F, a <br />memo/packet from Mike Gaffron that reviews mound installations in the City <br />and current level of expertise. <br />In reviev.’irg the Engineer's report. Exhibit D, the wetlands boundaries <br />as shown on Lots 5 and 6 are satisfactory. The Engineer recommends the <br />placement of 15" culverts at 2 designations on the plat (see Exhibit E). <br />Note that we would also recommend that existing drainageway within Lot 2, <br />Block 2 be relocated along the east lot line at the time of site grading.
