Sheet G
I, Verify that the hydrant detail/ specs call out the following information:
Fire hydrants shall incorporate an AFC - waterous Storz Nozzle. The hydrant pumper nozzle
shall be of one -piece design, compatible with a 5" Storz hose coupling. The nozzle shall be an
integral part of the fire hydrant and must be furnished by the manufacturer or authorized
distributor designated by the manufacturer. Storz adapters will not be accepted.
2. There appears to be many details missing, including but not limited to, heavy duty pavement
section, concrete sections for side walk and concrete car show pads.
Traffic (
1 . It is recommended that the entrance on Morning Dove Avenue be moved further south to line up
with the customer parking drive aisle. This will facilitate better traffic operations as the future
street is completed. Moving the access point will help maintain the integrity of the intersection of
58t Street and Morning Dove Avenue,
2. The turning radius from the parking lot to Memorial Avenue will need to be increased for the
delivery trucks so that they will not drive over the curb and to minimize the need for the trucks to
encroach into oncoming traffic lanes.
I It is recommended that the south radius at 58"' and Memorial Avenue be increased from 42 feet to
60 feet. Even with the larger radius, trucks turning right from Memorial to 58' will need to drive
into the west bound lane on 58" Street; however they will be able to remain on the pavement.
4. Revisions will be required on the traffic signal and loop detectors at Highway 5 and 58t Street.
M N DOT will need to review and approve these revisions.
5. It is recommended that 58" Street will be widened to four lanes from Highway 5 to Morning Dove
Avenue and then taper back to the existing two lanes on the west side of Morning Dove.
6. For the circulation of traffic future development of the entire Denny Hecker site will require
additional roadway improvements.
MNIF)nT lsri,pr,
I . The developer should contact MNDOT on the following issues;
a. Setbacks from MNDOT's right -of -way for proposed improvements.
b. Modifications 58" Street at H ighwaty 5 within M N DOT's right -of -way.
c. As stated above, any signal modifications at 58t Street and Highway 5.
