Plat/Construction Plans
Dear Mr. Doyle:
We have reviewed the
following comments.

Regarding the Zoning Change Request from Retail to Commercial-
Special Use Permit with Drive-Thru, we suggest the monument sign
not be indicated on the Site Plan at this time under the SUP but
rather be handled as a separate issue. Also, a Variance Request
should be added on the Site Plan for a north-drive access to be
allowed off of Denton Tap Road. These Site Plan revisions can be
made conditions of any motion when considering this issue at the
Planning & Zoning meeting with the revisions being requested to
be made prior to the Zoning Change Request going forward to city
Council.
Regarding the Final Plat we have the

following comments.

Per the city's Comprehensive Floodplain Management
Ordinance, paragraph 4 o~ page 34, a Floodplain Permi~ note
needs to be added to the plat. This site, however, is not
within the limits of any existing floodplain or floodway,
therefore, a permit number for development would not be
applicable.
Any proposed fire lanes outside the limits of the platted
site need to be dedicated by separate dedication
instruments. These instruments should be executed,
notarized and provided to the city prior to the Final Plat
being submitted to the city Council for consideration.
The floodplain note shown on the Final Plat is not required
to be on the plat, and thus, can be deleted.

The need for the Variance Request for a north-drive is due
to the Sub-Division Ordinance requiring, for a 35 mph
roadway, 100 feet be provided between drives and for a 40
mph roadway 120 feet be provided. Approval of the variance
would allow a driveway spacing of only 72 feet
approximately. Circulation will still exist without this
drive via the common access drive between McDonalds and this
site. Please reference the attached excerpts from the Sub-
Division Ordinance.
Regarding the Construction Plans we offer the following comments.
1. Power feed from TU Electric should be an underground feed
from Denton Tap.
Site should 'sewer (sanitary) from the rear as per the
original Preliminary Engineering plan. This will alleviate
the need for the applicant to open cut approximately 65 feet
across the new Denton Tap Road pavement (3 southbound lanes,
median and i northbound lane). Public safety and reduced
liability will be better assured for both the applicant and
the City with this requested revision.
The 2" domestic water tap should be in the same trench as
the fire hydrant lead tap if the new Denton Tap Road
concrete pavement is existing at the time the site develops.
This will alleviate the need for 2 street cuts or tunnels
(whichever is required by Public Works) and only require 1.
Ail pavement shall be required to be 6" thick, 3000 psi at
28 days with a 6" lime stabilized subgrade (6%). This
includes any drives. Also, no cushion sand is allowed
between the subgrade and the pavement.
Applicant must submit written permission from the property
owner prior to the City allowing any pavement to be placed
outside either the platted area or outside any fire lane
easement boundaries. This shall be required prior to
approval of the construction plans.
Please call if you have any questions.

DRIVEWAY RADIUS
All d~tveways tnte~sec%lng dedicated streets shall be built with o
cJ~culo~ curb =odtus connecting the six-inch ~oised curb of the ~oodwoy
to the destgn wtdth pavement o¢ the d~iveway, D~tveways shall be located
fo~ enough f~om the tnte~o~ p~ope~ty line to permit the curb ~odtus to
fall entirely in f~ont of the sub~ect p~ope~ty. ?he City Engtnee~ she]!
approve the d~tveway widths and d~tveway ~adlus at the time of site plan
~evtew p~ev~ous to issuance of any building permit. ]n o~de~ that the
definition of the location of the edge of pavement fo~ the thoroughfare
may be maintained, d~tvewoy ~adti sha]! always be designed to become
tangent to the street curb line. ~wo-woy d~tveways shall always be
designed to intersect the street at o 90-degree angle. One-way d~iveways
may be designed to intersect a street at o minimum 4S-degree angle.
D~]VEWAY SPACING AND LOCA?ION
The spacing and location of d~tveways shall be ~elated to
ad)acent d~iveways and nearby street intersections. The spacing
between d~iveways shall be dependent upon the speed limit of the
thoroughfare and a~e ~ecommended as follows: (see Figure 2l
