Josephine Woods Tree Preservat t <br />D <br />February 24, 2011 <br />■ Driveway was switched. to low side of lot to avoid. tree. <br />• Tree 4 1292 (32" Red. Of ak) <br />■ Cu.1 -de-sac location was kept southerly to allow for pad. placement south of tree <br />tree. <br />■ Road. grade/profile elevation was desi, ned. to ensure the aqjacent house pad. <br />elevation could. be set at an elevation to avoid. disturbance to tree. The proposed. <br />house pad. now matches right in with existing topography. <br />• Tree 4 1372 (27" Red. Of ak) <br />■ Cu.1-de-sac and. aqjacent house pad. location were chosen to avoid. tree. <br />■ Road. grade/profile elevation was desi, ned. to ensure the aqjacent house pad. <br />elevation could. be set at an elevation to avoid. disturbance to tree. The proposed. <br />house pad. now matches very closely in with existing topography near tree. <br />■ Common lot line, water main and. sanitary sewer routing location desi, ned. to <br />avoid. impact to tree. <br />■ Water main alignment was chosen to be on the south side of the sanitary sewer so <br />that a shallower installation trench would. be required. near the tree. <br />■ The proposed. path alignment was desi, ned. such that the proposed. grades would. <br />not conflict with the existing tree. <br />• Tree 4 1389 (30" White Oak) <br />■ A retaining wall will be constructed. to avoid. disturbance with the tree. <br />• Tree 4 1438 (35" Red. Oak) <br />■ A retaining wall will be constructed. just off the back of the proposed. house pad. <br />to avoid. conflict with existing tree as well as several others. Wall will also help <br />preserve maintain a native buffer to the existing homes. <br />• Tree 4 1440 (28" Red. Oak) <br />■ Same as tree 4 1 43 8. Trees 4 143 8 and. 4 1440 are very close together. <br />Tree 4 1562 (29" Red. Oak) <br />■ Road. grade/profile elevation was designed. to ensure the adjacent house pad. <br />elevation could. be set at an elevation to avoid. disturbance to tree. <br />■ Grading is designed. so that elevations match in area of tree. <br />■ A small infiltration basin is proposed. aqjacent to NE wetland. to meet drainage <br />requirements as a result of maintaining the existing grades by the tree. <br />Please call me at 612-767- with any questions or comments regarding the tree preservation plan for <br />the Josephine Woods pro'ect. <br />9 <br />Sincerely, <br />�« r J <br />Mark Rau.sch, PE (43480) <br />Alliant Engineering, Inc. <br />Alliant Engineering, Inc.
