Re: Cove of Nantucket Final Plat Comments
Dear Bridgette,
Please find attached with this letter the following:
• 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
• One (1) copy of the digital file of the final plat on diskette
Below are the answers to the Staff Review Comments for the Cove of Nantucket.
ENGINEERING:
Comment: TxDOT made the following comment on this plat: "Access driveways to SH6
must meet TxDOT's current `Regulations for Access Drive -ways to State
Highways.' Regulations are primarily based on posted speed limits and distances
between proposed and adjacent access points. Where posted speed limits are 50
MPH or more the required spacing between access points is 425. Developer
should coordinate construction activities with TxDOT Bryan Area Office for 2005
Nantucket Drive U -Turn Project w /conversion of frontage roads to one -way
traffic. Future development south of this site should consider location of
proposed SH6 ramps associated with the U -Turn Project. Appropriate data will
be required for any future permits at this site.
0 Answer: As mentioned in the Preliminary Plat comment dated March 21, 2005, the
entrance for Parkview Trail has already been constructed. It was constructed
under an old Preliminary Plat scenario. We are simply utilizing the existing
roadway apron. The spacing between Windrift Cove and Parkview Trail is
C r� /�B currently 480 feet. The TxDOT access criterion currently states for a one -way
V � frontage road that the spacing shall be a minimum of 425 feet. For a two -way
( frontage road, the access criterion requires 510 feet spacing. Because the apron is
existing and we will meet the criteria for a one -way frontage road (which is
currently under design and will be under construction within a year) we are
NO 1 'el. requesting that this location be allowed. We have also looked at the new exit
ramp and it exits south of Wayfarer Lane, well south of Parkview Trail and the u-
turn at Nantucket Drive is well north of Parkview Trail.

which lots) on the plat.
Xnswer: There are no lots proposed for zero lot line construction.
V ' omment: The application and FP do not show the same amount of parkland dedication. Are
3.7144 acres of parkland really in detention as shown on the application?
/Answer: Per our discussion on June 28 there are 3.71 acres of parkland dedication, of
4;kti
C which 0.14 acres will be used for detention. The remainder of the detention will
« be located in common areas indicated on the Final Plat.
/Comment: The application asked for a statement addressing any differences between the
Final Plat and the approved Preliminary Plat. The response given on the
application was "Please note that lots 1 -29, Block Two..." Please clarify.
✓Answer: The response should have read, "Please note that Lots 1 -29, Block 2 of the Cove
.0 (k of Nantucket Subdivision have been shifted in order to accommodate the
, in detention in the identified 0.57 acre common area."
n�
v omment: Define PDE. All public drainage easements have to be improved to City
standards.
/Answer: We have provided a legend on the Final Plat indicating what PDE, PUE, etc.
represent. In addition, all public drainage easements (PDE) will meet City of
College Station standards.
/mment: The median shown in the cul -de -sac of Twin Pond Circle will need a PIP if not
/ designated as Common Area on the Plat.
,/Answer: This area has been designated as a common area on the final plat with a 50' ROW
at all locations on Twin Pond Circle.
✓Comment: Is there enough width in the PUE on Lot 58 to allow the sanitary sewer main to be
5.5' from PUE boundary?
✓Answer: We have adjusted the easement to ensure that there is at least 5.5' from the
proposed sanitary sewer to the PUE boundary.
`omment: You will need to dedicate a public drainage easement over the portion of drainage
channel that has been concrete lined and is located on your property.
' 4nswer: A 20' public drainage easement has been dedicated on the Final Plat.
0 Comment: Remove note "Grading by City of College Station" from construction documents.
The City is not prepared to perform this work at this time.
O Answer: While there is no comment on the Final Plat regarding the grading of the drainage
channel adjacent to the Cove of Nantucket property, the City of College Station
Department of Public Works has agreed to fill the existing channel and regrade
the channel in the 50' PDE on the South Hampton property. This discussion is
detailed in a letter to Mark Smith, Director of Public Works dated June 30, 2005.
I have included a copy of the letter for your reference.
