iiilbelink/Vogt - Site Evaluation for Proposed Subdivision <br />December 22, 1987 <br />Page 4 of 5 <br />Lot S, ,Block +1 <br />Both sites need mounds; the boring logs suggest that something <br />other than Hamel soil is present, and some sand pockets were <br />found. <br />Lot ,1, _ Block 2 <br />Primary site proposes trenches in an area mapped as Lester loam, <br />which is consistent with that. soil type. Alternate mound site is <br />in area of deeper topsoil lout probably not a Hamel as mapped, <br />more likely a I.erdal o.- LeSesr 1.oam based on the soils indicated <br />by the boring logs.. <br />Lot__2,,,_§lock. 2 <br />Same comments a, for Lot 1, Filock 2. Primary site - trenches are <br />consistent with soil types mapped anti indicated on borings. <br />Alternate mound site is also consistent for those soils. <br />Lot 1, Block 3 <br />Primary site - trenches. Staff will do confirmative boring; <br />apparent sandy pocket is shown on soil survey. Alternate mound <br />site seems OK and leaves a number of locations for house <br />placemen'-. May be the best lot of the bunch. . . <br />Sua ry: <br />In general, the report provides :he minimum basic information needed <br />to approve the septic sites; however, --hat information is poorly presented. <br />Some of the hole locations are inaccurate based on the site inspection, and <br />dimensioned incorrectly; and no re'ati%e hole elevations were given, which, <br />except for the fact thsc a topographical map is a ✓ai lable, is something <br />that should be provided in every case. I am recommending that the City <br />require that certain lots undergo additional testing to find better <br />alternate sites to free up some res`rictive building envelopes (and in one <br />case to find an alternate site that is on higher, dryer ground). I have <br />also recommended that the east/west road south of Lot 6, Block 1 be moved <br />50' to the south in order to give that lot some flexibility. <br />I have also recommended that this item not be brought to the Council <br />for preliminary plat approval until the changes and additional testing <br />noted a-e complete nor until a copy of the proposed plat (with topography) <br />showing the actual surveyed locations of all boring holes has been <br />submitted. ^ <br />
