1. The curb detail provided is only permitted for temporary curbing. A monolithic curb is
required. Please see the Site Design Standards.
2. The buffer wall is required to extend the length of the property line. Staff cannot allow a
variation to this requirement. The Design Review Board may hear a waiver request, if
you wish.
3. Please include the caliper (min. 1.25") for a single cane for non-canopy trees.
4. Please note that any changes made to the plans, that have not been requested by the
City of College Station, must be explained in your next transmittal letter and "bubbled" on
your plans. Any additional changes on these plans that the City has not been made
aware of will constitute a completely new review.

,i1/ The end island just south of the driveway from Wellborn Road states that it is 275 square
feet in area, but is smaller than islands labeled 180 square feet. Please correct.
v The minimum end island size is 180 square feet.
X Are the number of breaks in the curb shown adjacent to the detention pond needed?
„4 Parking spaces that are only 18' in length require a minimum clear space of 2' at the end
of the space. The parking spaces adjacent to the detention pond will not have the
minimum clear space because screening is required around the detention pond area.
"Compact" parking spaces are not permitted. 18-foot spaces are permitted, but cannot
have a wheel stop and must have 2' clear space at the end of the space.
%,1 Interior parking islands are required in the interior parking rows. 180 sq ft. of area per 15
spaces.

located behind a dumpster enclosure.

ENGINEERING COMMENTS NO. 1
1. Please provide written response to all comments.
2. I am confused by your submittal. You seem to be basing your design with the widening of
Wellborn Road being complete. I do not have start time for TxDOT's project. As proposed,
you will need to wait until the widening project is complete, or design you site on existing
conditions with allowance for their project. How are you coordinating this project with
TxDOT's widening? Also, we need a total of four copies of plans for permit. Please submit
an additional, or four revised to show culvert.
3. Access driveway to Wellborn shall be right-in, right-out only, due to a future raised median at
this location.
4. Are you not proposing a culvert under the proposed driveway off Wellborn? As shown you
will be blocking drainage in the roadside drainage ditch.
5. Provide sizing calculations for the culvert for you proposed driveway.
6. Driveway permit needs to include stormwater discharge and culvert sizing calculation
information which was not provided. Your Driveway Permit will be forwarded to TxDOT
once this information is provided and reviewed for completeness.
NOTE: Any changes made to the plans,that have not been requested by the City of College Station,must be explained in your next transmittal
letter and"bubbled" on your plans. Any additional changes on these plans that have not been pointed out to the City,will constitute a
completely new review. Page 3 of 5
7. Please show all existing and proposed public water mains and sanitary sewer lines in close
proximity to this site.
8. The 6-inch waterline extending from Steeplechase Subdivision Ph.7 already serves one fire
hydrant. We are concerned that an additional fire hydrant may produce excessive
velocities. Please verify.
9. Please show existing and proposed contours on grading plan.
10. Please provide details on storm sewer tie-in in TxDOT ROW. Junction box will be required.
11. What is TxDOT's schedule for the storm sewer installation and your contingency plan since
it appears that your site will be developing before the storm pipe gets there?
12. Please show all easements on utility plan. It's difficult to tell if all of the infrastructure is in
appropriate easements.
13. Provide detail of sump. Structures are not allowed in a PUE.
14. Fire flow report must verify that the proposed fire hydrants will meet minimum flow, velocity,
and pressure requirements as specified in the BCS Unified Design Guidelines. Please
revise.
15. I am assuming there is a fire wall between Space A and Space B from the way the report
provides the information. Please revise report to indicate the construction of fire wall that
allows for the independent fire flow requirements.
16. Address discrepancy between wastewater flows provided in the report (125gpm) and the
Site Plan (1.74gpm).
17. It appears that your pavement and curbing blocks the drainage flow path of the adjacent
property. Please explain in your drainage report any negative impact on the adjacent
property and any necessary mitigation.
18. Please provide drainage report.
19. Please submit erosion control plan.
20. Please provide Engineer's Cost Estimate for public infrastructure.
21. Please submit"Letter Acknowledging City Standards".
22. Include BCS Unified Details with Civil Construction Plans.
23. Additional comments may result from review of required documents not submitted with initial
