SUBJECT: WILLIAMSGATE PH 3 (FP) - Final Plat
Staff reviewed the above-mentioned final plat as requested. The following page is a list
of staff review comments detailing items that need to be addressed. If all comments
have been addressed and the following information submitted by Monday, February 28,
10:00 a.m., your project will be placed on the next available Planning and Zoning
Commission meeting scheduled for, March 17, 2005, 7:00 p.m. in the City Hall Council
Chambers, 1101 Texas Avenue.
Two (2) 24"x36" copies of the revised final plat;
Ten (10) 11"x17" copies of the revised final plat;
One (1) Mylar original of the revised final plat; and
One (1) copy of the digital file of the final plat on diskette or e-mail to
nmanhart@cstx.gov
Please note that Sewer Impact fees ($300/LUE) are due prior to filing the plat (18 lots x
$300 = $5,400). Upon receipt of the required documents for the Planning & Zoning
meeting, your project will be considered formally filed with the City of College Station.
Please note that if all comments have not been addressed your project will not be
scheduled for a Planning & Zoning Commission meeting. Your project may be placed

Project: WILLIAMSGATE PH 3 (FP) - 05-00500015
PLANNING/ENGINEERING
1. Sanitary Sewer and Lift Station Report and Design are currently under review by
City of College Station Water and Wastewater and will return comments as soon
as possible.
2. Fire Flow Report is inadequate. The fire flow report is based on information from
an existing City of College Station water system which will not be connected to
the system supporting this development. Each phase of construction should
stand alone and should be analyzed independently as well.
3. The detention design in the Drainage Report appears to reflect that additional
flows could be released from the pond. Furthermore, the pond volume based on
calculated depths, proposed volume provided, and the volume approximated for
the pre/post flows are not consistent. Please clarify. Common Area "E" is
subject to change based on the final Drainage Report and final Sanitary Report.
4. Site grading must be revised such that there is not a propensity for flooding or
future blocked drainage due to flows across lots and the absence of a drainage
system in these locations. Extensions of drainage systems would require a PUE.
Additionally, please note that approximately 12 lots have over 2ft of fill which will
require either additional beam depths for the house foundations or the fill be
placed, compacted, and tested to satisfy 95% Standard Proctor (ASTM D-698).
5. FYI: This development is located in a sewer impact fee area and a fee of
$300/LUE is due at the time of the filing of each plat (Phase 1: 33 Lots = $9,900;
Phase 2: 31 Lots = $9,300; Phase 3: 18 Lots = $5400).
6. The water lines are located outside of ROW and in some cases located 25ft
away from back of curb. These lines may be relocated within the ROW to
remove or release the adjacent easement.

ENGINEERING REVIEW
COMMENTS No. 2
Construction Plans Comments:
1. Clarify the proposed utility limits of Phase 1.
3. The waterline connection to the Wellborn line requires the gate valve on the
proposed line side, in addition to Wellborn's requirements.
4. Two sets of waterline layers are left "on" throughout the plans.
12. Note and depict that the water and sanitary crossing near Hancock Sta.
9+00 should be in accordance with TCEQ ch.290.44(e)(4)(B)(iv)(II) such
that the encasement should be on the sanitary and separation from the
encasement to the waterline shall be a minimum of 6 inches. Additionally,
depict the storm, water and sanitary in profile at this crossing throughout the
plans. (This appears to apply to Phase 3 as well.)
18. Depict the proposed culverts for each of the two intersections of Hancock
Loop and Rock Prairie Rd and provide associated design calculations in the
drainage report.
19. Site grading at the rear of the lots to provide a swale appears to be graded
backwards. Additionally, a swale is also needed at the rear of lots between
Tony Court and Shelbea Court.
29. Provide the temporary culdesac easement.
30. Provide profile detail of all storm sewer infrastructure leading into the
detention pond past Junction Box 1 and Inlet 3.
32. (C10: This comment appears to apply to Phase 2) extend the sanitary
sewer to approximate Sta. 22+10 to make the last long side service
perpendicular to Hancock Loop.
34. Provide the plan and profile of the 8 in. northern extension out on Shelbea
Drive.
39. (C16) The concrete valley gutter should be 4 ft. wide with 12 in. toes and a
6 in. depression per Figure VII — 1 of the Drainage Design Standards.
Final Plat Comments that apply to the Construction Plans:
1. Sanitary Sewer and Lift Station Report and Design are currently under review
by City of College Station Water and Wastewater and will return comments
as soon as possible.
2. Fire Flow Report is inadequate. The fire flow report is based on information
from an existing City of College Station water system which will not be
connected to the system supporting this development. Each phase of
construction should stand alone and should be analyzed independently as
well.
3. As previously commented, there appears to be an error the detention
analysis in that the proposed detention volume is significantly smaller than
the estimation of the difference of the triangular hydrographs. It may be
worthwhile to meet on this topic.
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 of College Station will constitute a completely new review.
