RE:sICreekview00-01 Drive Extension and Freeport Parkw~...----
Dear Michael:
The following letter is in response to your comments and mark ups dated March 27,
2001.
Provide the new City logo on Cover Sheet.
Response: The new logo is on the Cover Sheet.
Make the changes to the Council members' names as noted on the Cover Sheet.
Response: The Council has been revised on the Cover Sheet.
~. Show the City's project number (ST 00-01 ) on the Cover Sheet.
Response: Project number is shown on the Cover Sheet.
4. Consideration should be made to adjust the grade on Creekview Drive as indicated
on Sheets 2 and 3. If the grade can be raised, it would eliminate the need to grade
on the south side of Creekview and possibly the construction of retaining wall.
Response: By adjusting the grade, per City comments, we would need an
additional 900+- cubic yards of fill. The proposed wall will be 1.5' tall
modular block wall (Pavestone), with the color matching the walls
found at Wagon Wheel Park. Please contact me if you would like to
discuss this in greater detail.

5. Need to verify if the existing inlets on Creekview west of the proposed extension
were designed to handle the additional 6 cfs. If not, then curb inlets may need to
be provided near station 0+50.
Response: This is only an issue if we eliminate the walls and raise the road per
the City comments.
6. The proposed radius for existing driveway on the south side, of the west end, may
be difficult to construct since it may conflict with existing storm drainage junction
box. The junction box may have to be adjusted. Please verify.
Response: According to the survey it appears the $0' radius will work fine, but
we will verify the dimensions in the field. Would it be possible to
adjust the radius in lieu of the inlet? ~
TxDOT pedestrian rails should be used at all locations which will require railing.
~ Response: A permanent barricade (guard fence) has been added to the plans,
per the Std. Construction Details sheet SD3.
~. If a retaining wall is required on the south side of Creekview Drive, then
consideration should be made to stamp and color the concrete retaining wall.
~'"~-'~ Response: We planned on using a modular block (Pavestone) wall that will
match the walls used at Wagon Wheel Park.
Show the location of the proposed driveways on the south side of Creekview
Drive. You can contact Chuck Stark, P.E. with Graham & Associates at metro
81 7/640-8535 for this information.
Response: We contacted Chuck Stark regarding the proposed drives and he said
the driveways were not designed yet. They will be designed in a
future phase of development.
