Review File: Homestead Road Preliminary Plat Exhibits Engineering Review March 29, 2017 Page 2 of 3 Sheet Specific Comments: Plat Sheet: 1. The plat must be revised in the southeast corner of Lot 3 to remove the note about vacated portion of road easement. The City is not vacating that easement. Additional easement must be dedicated to encompass the 100 year elevation of the existing pond. A portion of the road easement may be vacated with the plat if it is outside of the new pond easement. 2. New road right-of-way indicated as "possible future right-of-way" on the preliminary plat sheet must be dedicated with the plat. Preliminary Plat Sheet S1: 1. The dashed line indicating possible future right-of-way must be changed as noted above. Preliminary Plat Grading Plan Sheet S2: 1. The dashed line indicating possible future right-of-way must be changed as noted above. 2. The lot dimensions must be turned off on this sheet. 3. The line weights must be modified to differentiate between existing and proposed conditions. 4. Consider rotating the sheet and enlarging the scale to show the southern 300 feet of the lots as this is where all of the new work is occurring. 5. The proposed rain garden leader for Lot 1 runs into an existing contour line. Work needs to be done on the plans along 166th Avenue to improve readability. 6. The sanitary sewer labels must be turned off on this sheet. 7. The bottom of the rain gardens must be 3 feet above groundwater level to be considered eligible for infiltration credit. A hand auger boring must be performed in each proposed rain garden. The information from the boring can be shown on the final grading plan, 8. The proposed garage elevation must be listed for lots 1 and 3. 9. The FEMA 100 year flood elevation must be shown on this sheet. The lowest floor elevation of all development, including basements, must be at least 3 feet above the highest anticipated ground water table, 2 feet above the designated or designed 100-year flood elevation, or 1 foot above the emergency overflow, whichever is higher.
