We have reviewed the preliminary plans and drainage calculations submitted regarding the proposed

submitted.Following are our preliminary comments and recommendations:
Sheet C200—Proposed Site Plan
1. There should be sidewalk along the west side of the property in the boulevard adjacent to the right-
of-way line.
2. Label and reference the improvements to the corresponding details on detail sheets.
3. Provide a detail for the retaining wall.
4. Add a note to the site plan sheet requiring a"butt joint"where the driveways tie in to the City street.
5. Refer to the Fire Department review of fire lanes and circulation.
Sheet C300—Storm Drainage and Grading Plan
1. The southerly elevation note on the northerly driveway is covered by the existing sanitary manhole
note.
2. Label the swale grade on the east side of the building.
3. The riprap shall be installed per City detail plate STO-13. Include plate on corresponding detail
sheet.
4. The storm sewer that serves the site will be private and maintained by the owner.
5. A note should be added to the plans stating any work performed within the infiltration area should
be kept to a minimum.In the event heavy machinery is used within the infiltration area,disk tilling or
other means to loosen the soils may be required to allow for proper infiltration.
Sheet C400—Utility Plan
1. It is recommended that an 8-inch line be considered for the water service to the hydrant and the
building in order to provide the maximum flow possible.
