Robert Posthumus, Lots 58 & 59, orse Island Par). January 19, 1988 Page 2 of 3 b) For the mound systems, t), : setbacks are 75' from the lake, 75' from the pond, 20' from any structure, 75' from any well. c) For the well the required setbacks are 75' from the lake, 5' from the prope _ ty line, 3' from any portion of the house or overhang, 75' irom any portion of the d.rainfield system, and 50' from the septic tanks (note that the State of Minnesota Standards allow the well to be 50' from the shoreline and 50' from any portion of tha septic system or tanks). 9. Haviazg drawn all of those constraints onto a copy of your proposed site plan, with your proposed house location and size, in my opinion the required primary and alternative sites cannot be fitted within the property boundaries. 5. Howe% , it is also my opinion that with a number of variances and careful ..ite planning, perhaps in addition to a reduction in the size of the proposed house, this lot may in fact 1)e suitable as a building site. The revisions that I see being potentially feasible are as follows: a) Place t;,e well at a location 5' f the southern side lot: line and 50' from the lakeshore (this z ..ires a conditional use permit and variance approval from the City Council). b) Move the hLise nearer to the southeasterly lot line to a point as near as 10' from that lot line (this also requires a viriL cc approval from the City Council). ,,) Reduce the footprint area of the structure so that setbacks of 20' from the mound systems ^an be maintained. The :sigr.ate:d primary and alternate drainfield sites then world be on the f'_at portion of the top of the hill, and near the base o;` the hill -year the lot corner as shown (-z the attached conceptua:_ diagram. .used on my discussion with Dr. Machme , the point from which moun system setbacks are measured would be defined by the required bas. 1 dimensions of the mound syste - (i.e. for the primary site on top of the hill for z 21 minute p-r inch pert: rate and slopes lest- than 3%, the defined edge of the tree* ment area is 5' outside :he rock bed, and we would still expect to see a 10' side lot line tback and 20' house setback from that be ndary). Also, for th iternate site downhill, wi,ich because of a s .e.:�per slope and faste_ pert rate has a defined tr- :tment area u• --ath and downhill f i o,n the rock bed, we would again expect that prop?rty line setback be maintained along with the 20' house s,. k. Thesn are also show; on the attached diagram. This configuration would appear to meet the re-,, :red setbacks from property l iaes ..id from the lakeshore and tho pond. In this configuration we would al.loa addition of fi11 material,; outsi,'e • e . esian,+ed treatment area up to the lot 1 ines (but no-_ outside them).
