The plan proposes to combine the lots and build one new home on the new parcel. We have the <br />following comments with regards to engineering matters: <br />• The proposed grading plan should be revised to show a defined swale along the northwest lot line to <br />convey stonn water towards the lake and away from 1270 Spnicc Place. <br />• Retaining walls that exceed four feet in height require an engineered design and details. <br />• Driveway grades should be noted on the plans and shall not exceed 10%. <br />• 1280 and 1290 Spruce PImc have individual sewer and water services. The new home will require one <br />water and one sewer service. The unused sewer service should be removed to the City right-of-way <br />and sealed to prevent infiltration into the sanitary sewer system. The old water service should be <br />abandoned and the curb stop shut off. Sewer and water removals shall be inspected and approved by <br />the City public works department <br />• There Is an application to improve the adjacent property to the southeast (1300 Spruce Place), grading <br />along the common lot line should be coordinated so drainage fiom both parcels is directed towards the <br />street or the lake. <br />• Erosion control should be instsUed. inspected snd approved by the City prior to any work on the site <br />If you have any questions please call me at (651) 604-4863. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLQC A ASSOCIATES.
