Review File: Homestead Road <br />Preliminary Plat Exhibits <br />Engineering Review <br />March 29, 2017 <br />Page 2 of 3 <br />Sheet Specific Comments: <br />Plat Sheet: <br />1. The plat must be revised in the southeast corner of Lot 3 to remove the note about vacated <br />portion of road easement. The City is not vacating that easement. Additional easement <br />must be dedicated to encompass the 100 year elevation of the existing pond. A portion of <br />the road easement may be vacated with the plat if it is outside of the new pond easement. <br />2. New road right-of-way indicated as "possible future right-of-way" on the preliminary plat <br />sheet must be dedicated with the plat. <br />Preliminary Plat Sheet Si: <br />1. The dashed line indicating possible future right-of-way must be changed as noted above. <br />Preliminary Plat Grading Plan Sheet S2: <br />1. The dashed line indicating possible future right-of-way must be changed as noted above. <br />2. The lot dimensions must be turned off on this sheet. <br />3. The line weights must be modified to differentiate between existing and proposed <br />conditions. <br />4. Consider rotating the sheet and enlarging the scale to show the southern 300 feet of the lots <br />as this is where all of the new work is occurring. <br />5. The proposed rain garden leader for Lot 1 runs into an existing contour line. Work needs <br />to be done on the plans along 166th Avenue to improve readability. <br />6. The sanitary sewer labels must be turned off on this sheet. <br />7. The bottom of the rain gardens must be 3 feet above groundwater level to be considered <br />eligible for infiltration credit. A hand auger boring must be performed in each proposed <br />rain garden. The information from the boring can be shown on the final grading plan, <br />8. The proposed garage elevation must be listed for lots 1 and 3. <br />9. The FEMA 100 year flood elevation must be shown on this sheet. <br />The lowest floor elevation of all development, including basements, must be at least 3 feet <br />above the highest anticipated ground water table, 2 feet above the designated or designed <br />100-year flood elevation, or 1 foot above the emergency overflow, whichever is higher. <br />
