RE: Brooke Bill Viljage -' Preliminary Plat
Dear Lee: ¢
Attached are revised copies of the plans. The following is a summary of the revisions we
have made to address your comments dated September 7, 2004.
Comment. Lot 01, Block A does not include the side yard setback line. It should be
indicated as 20 feet. Also the front yard and rear yard buildings lines should be extended
across the PD portion of the lot.
Response: The building line extends to the PD limit on Lot 1, Block A, since no
commercial buildings are allowed within the P.D.
Comment. The vicinity map should indicate that the site extends from Keaton Road to iH
35. it currently stops about 2/3 the distance.
Response: The vicinity map now shows site extends from Keaton Road to IH 35
service road.
Comment. Since the existing downstream storm sewer system appears to be designed for the.
10 year storm and'.then must demonstrate that the 100 year storm will remain within the right
of way of the downstream streets until it reaches Duck Creek.
Response: See attached drainage report. We do not intend on increasing flow in
Keaton Road between the site and Duck Creek Road.
Comment. Recent storm events have resulted in the flooding of a home on Rising Star,
adjacent to Duck Creek. Please demonstrate that the additional flows to Duck Creek on the
upstream side of the Keaton Road culverts will not further impact the flooding or cause the

home to flood more often. The City is communicating with the county regarding
improvements to the culverts.
Response: See attached drainage report. We do not intend on increasing flow in
Keaton Road between the site and Duck Creek Road.
Comment. Developer originally proposed making downstream drainage improvements in
lieu of detention. These improvements should be identified and resolved prior to approval of
the preliminary plat.
Response: See attached drainage report. We are proposing on -site storm water
management, facilities to be maintained by the homeowner's
association. , • As.` an alternate,: owner. may contribute to the off -site ;
improvement as -discussed.
With the revised drawings and ;:drainage report, ,.we should meet the City of Sanger
requirements and hope that you will be able to recommend approval of the Preliminary Plat.

RE: Brooke Ifill Village .
Dear Lee:
As we have discussed, the City of Sanger does not appear to have specific drainage
requirements (fisted in their Subdivision Ordinance. We have prepared the preliminary
drainaiq computations in accordance with the City of Denton, 1990 Drainage Criteria
Manual. Our preliminary cpmpptations address some of the concerns and some of the
dcvelopment options that might be required on the Brooke Ifill Village project as follows.
• Keaton. Road, in its existing condition, does not have capacity within its curbs and
pipe system to convey th} 10-year storm. Our estimates show that a 100-year storm
will use approximately • 94% of the allowable capacity within the right-of-way.
Development of Brooke ITill Village will increase the 100-year storm by
approximately 15% over existing conditions. This will either overload Keaton Road
or cause additional flow to go down Laney and Benjamin Streets.
• Based on the preliminary flow estimates, we have estimated that approximately 1
acre-foot of detention storage will be required to mitigate the impact of the proposed
develop rent. The , attached on -site Detention Pond cost estimate shows the
anticipatk. cost of confietting a proposed detention pond to the proposed on -site
storm sewer system.
• Our prelimmiry drainage computations indicate that the Laney Street system does not
appear to meet the 1990 City of Denton Drainage Criteria. The attached off -site
storm sewer cost estimate assumes that a storm sewer system be constructed. from
Duck Creek Road along Laney Street to Keaton Road. We have tried to size the

system so that it will provide relief to the Keaton Road system and convey up to the
10-year storm underground along Laney Street.
From our discussions it appears that there is a home near the intersection of Keaton Road and
Duck Creek Road that is already experiencing flooding downstream of Brooke Hill Village.
Either a detention pond to mitigate run-off increases or off -site improvements to mitigate
damage potential appear to be needed to protect our clients from potential litigation due to
the proposed development.
From our discussions, it appears that the Council may be more interested in participating in
an upgrade to the Laney Street system than allowing an on -site detention pond. After your
review of this information we would like to meet with you to discuss your recommendations
to the City, and` see if there is additional information that would assist you with your
recommendation,.
Sincerely,

Re: Item 2 - Copperfield Estates
This item is being placed on the agenda with staff s recommendation to deny it. A plat must be
acted on within 30 days of receipt, unless a waiver has been received from the developer. The
insufficient items on the engineer's letter have not been addressed, and a waiver has not been
received. The surveyor indicated he did not feel the developer intended to proceed with this plat.

Preliminary Plat
Smith:
Wison Engineering recommends &nt'af of the preliminary plat. The site is located in the
mtraterritorial jurisdiction (ETA of the City of Sanger. Therefore Denton County
regulations must be met or exceeded as well.
Dur comments include:
> Provide a turn around at the end of the drive to accommodate emergency and
service vehicles as well as visitors.
➢ The preliminary plat must inc)ade all of tlae tract owned by Thomas J. Zimmerer.
➢ A street variance is needed from the City for a private access in the ETJ. Confirm
Denton County will allow dlw private access easement to serve the proposed 6
ots.
