frontage?

Please indicate why two curb cuts are necessary to serve this site.
4. Please indicate 30 -foot minimum return radii at the entrances.
5. 30 -foot is the maximum width for commercial curb cuts.
6. Please confirm if there is curbing along the north side of Northwestern Drive. If there is not

the entrances within the right -of -way be curbed and depressed curbing be installed across each
entrance.

8. Please verify with the DOGS the need for sidewalk or path across the Northwestern Drive
frontage.
9. Please replace Details I and 2 on Sheet CLA with City standard details.

use path across the Northwestern Drive frontage.
14. All BMP's shall be contained in easement per Section 701.07 of the Storm Water Technical

considered when establishing the MFPG and MLAG elevations.
16. Please establish the MFPG and MLAG elevations and include the definitions for each in the plan
set.
17. Please confirm if the building will be a slab on grade.
18. Will the 90- degree turn in the swale at the north end of the eastern parking area be problematic in
the long term?
19. If the detention system is remote, what is the flood route from this property to the detention
facility? Are the pipes under Northwestern Drive sized for the 100 -year storm from the upstream
watershed in the developed condition?
