K Please add/show the sidewalk along Rock Prairie Road. Sidewalks are required on both sides of all streets
having a right-of-way width equal to or greater than sixty feet(60').
Per our discussions at the pre-development meeting and subsequent meetings with Matt
Robinson, we understand that the sidewalk is intended to be constructed as part of the Rock
Prairie Road widening project currently under design. Therefore, we have not included any
sidewalk within the right-of-way with this submittal.
+'� The pedestrian walkway will need to connect to the public street sidewalk.

v1'0. Provide a general note that all signs are permitted separately.
Comment Addressed. See note#15.
11. A 15' buffer yard with a minimum 6' wall will be required along the East/Southeast side of the project. In
addition a buffer will be required along the northern portion of the property when that phase develops.
Please provide a wall and buffer along the eastern portion of the property.
The site plan has been modified to include a 15'buffer yard along the northeast and southeast
property lines. We have applied the standard listed in UDO section 7.6,F,4,a "Minimum Buffer
Standards — Substitutions" and intend to preserve the existing natural vegetation along these
property lines. We have provided a 6'chain link fence inside the property for security purposes.
We have also added a note to the landscape plans which states, "Prior to obtaining a certificate
of occupancy, the City may at their discretion conduct a visual inspection of the preserved
vegetation within the buffer yards. In the event that the existing vegetation is not of sufficient
density to provide 100 percent opacity to a height of 6'above the property line, the contractor
shall install evergreen shrubs of a 15 gallon minimum size in the identified locations within the
buffer yard so as to achieve the previously stated standard."
11'2. As per the phone conversation with Mark Delgado, a Zoning Board of Adjustment application will be
submitted for a variance request to section 7.9.E.4.d, requiring that a 10' sidewalk be placed along the full
frontage of any facade facing a public right of way. Site plan approval will not be able to be granted unless
the request is approved.
The client has decided not to pursue the zoning variance. We have added the required 10'
sidewalk and tree wells to the plans.

International Fire Code.
Comment addressed.
21. Sheet C-11- Hay bales are required than stone overflow.
Comment addressed.
22. Drainage Report- Please includes a drainage area map in the report. The proposed drainage areas listed in
the report do not match those shown on Sheet C-07. Additionally, based on the given information it is
unclear whether post-development flows are less than pre-development flows.
The site is located within an "evaluation" area for the Lick Creek watershed. We have
performed our detention evaluation based on the existing flow at the existing culvert crossing
for Rock Prairie in order to not increase flows at the culvert crossing. The drainage basins in
the HMS modeling reflect the site as a whole for the purpose of the detention pond sizing and
outfall design. We have utilized rational method to size on site storm systems. An additional
drainage area map has been added to the drainage report to clarify the drainage basins utilized
in the HMS model.
23. Drainage Report- Please clarify why the existing and proposed total sub-basin acreage does not match in
the"Drainage Information"table.
The table has been updated to correct this.
24. Drainage Report-Please provide a drawing showing the location, length, and flow lines of conduits R-1 and
R-2.
Conduit R-1 has been removed from the model. Conduit R-2 represents the existing borrow
ditch and has been renamed to "Exist Borrow Ditch".
25. Drainage Report-Please provide sizing information for the proposed discharge pipe from the detention pond
and the two conduits beneath the driveway. The surface treatment should be based on the design velocity
on the downstream side of the conduit.
Comment addressed. Sizing information has been added to the plan set. Culvert calculator
output has been added to "Appendix C"as well as the plans.
26. Drainage Report-Please clarify why a roughness coefficient of 0.15 was used in the"Hydraulic Conduit
Information"table.
The coefficient of 0.15 was taken from Appendix C of the drainage ordinance to represent the
existing grass lined borrow ditch along the road.
27. Drainage Report-A minimum side slope of 4:1 is required for trapezoidal channels.

Memorandum
To: Matt Robinson
From: Chris Harris
Subject: ADT Self Storage, 7103 Rock Prairie Road
Response to City Comments
Date: November 24, 2008
This memorandum is to address the City of College Station staffs comments on the above mentioned project as
received by Kimley-Horn and Associates, Inc. on November 17, 2008. The following information has been
included in this submittal for your review.
• Eight set of construction documents with revised site plans and landscape plans
• One set of landscape plans
Please find the written responses to staffs comments on the following pages. The original city comment is listed
followed by our response in bold print.
1. Site Plan—Please include the turning radii exhibit as a sheet with the construction documents.
Alternatively,the radii can be shown on the site plan without the outside radii and path being shown.
The fire truck turning radii have been added to the plan set as a separate sheet.
2. The landscape plan is showing trees located in the drive aisle/15' P.U.E. on the eastern side of the
property. Please revise.
The trees that were shown in the drive aisle were existing trees from the tree survey. They have
been erased from the plan.
3. Please revise the acreage description as shown on the landscape plan to match the site plan.
Acreage descriptions have been updated to match the site plan.
4. From speaking with the development engineer, a concrete swale will be built going throught the detention
pond. Please verify that the tree plantings will not interfere.
The proposed swale has been added to the landscape plan. It will not interfere with the
proposed plantings.
5. Staff was only able to count 100 Skyrocket Juniper's. Please revise. As an FYI, not including at least one
additional Juniper will put the proposed landscape plan under the required point requirement.
The additional 11 Junipers are located on the eastern end of the detention pond.
6. FYI, at the northwest corner of the tract two non-canopy trees may be required to be planted to meet
minimum spacing requirements as mentioned in 7.6.F.2.b
A note has been added to the landscape plan to address the possibility that additional plantings
may be required in the buffer area. All existing trees were not surveyed in the buffer yards,
therefore we prefer to address this issue on a case by case basis during construction.

SITE PLAN
1. Please correct note#5.
Note 5 has been revised to state "...0-3 and A-0"
2. The dumpster pad will need to be revised. A single 300-gallon container can use a 10'x10' enclosure, but
will need to be operated from the side. Another option would be to increase the dumpster enclosure to
12'x12' to allow for a single(one eight-yard) dumpster to be used which would allow for the existing
driveway approach. Please contact Wally Urruita at 979.764.3841 if you have any questions.
Dumpster enclosure has been revised to a 12'x12'enclosure.
LANDSCAPING
3. All easements are not being shown on the landscape plan. In addition the proposed 20' PUE as shown
measures 25'.
Easements have been updated to match the site plan.
4. Please show the tree survey/existing vegetation for the buffer areas as shown in the previous submittal.
Tree Survey has been added.
5. As per the Development Engineer, all trees located within a PUE will need to be moved. Shrubs are
allowed to stay within the PUE's. The trees located along Rock Prairie Road will need to be moved to the
detention pond to be able to meet streetscape requirements. In addition there are approximately 4 trees at
the rear of the property that are within a PUE. Note#16 actually states that the trees shall be planted at
least 4 feet outside any utility easement.
Trees have been removed from PUE's.
6. Please proved a general note station that any portion of the existing vegetation buffer not meeting sufficient
density to provide 100 percent opacity to a height of six feel will be require the installation of a solid pant or
hedge wall that is greater than six feet in height with approximately 100 percent opacity. As an FYI, all
shrubs planted for a hedge wall must be a minimum of 15 gallons each and the solid plant or hedge wall
must be evergreen.
General note has been added.
7. The crepe myrtles are listed as a non-canopy tree which earn 40 points per tree. Please revise the point
value,total points for crepe myrtles and total points claimed.
Point totals have been revised.
8. Please note that 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 the plans that the City has not been made aware of will constitute a completely new review.
The 6'CMU wall has been removed from the south east portion of the site and replaced with a 6'
evergreen hedge. 4(01t5

3. The tree wells along the front of Building A are required to have one canopy tree for every 6' in length. Non-
canopy trees can be substituted provided that the number is doubled. Currently as shown there are 8 non-
canopy trees. 7 canopy trees are required, please add an additional 6 non-canopy trees in tree wells or
show 7 canopy trees in the tree wells on the landscape plans.
Plan revised to show 7 canopy trees in tree wells.
4. FYI, the calculation for the streetscape requirements is (393.25 L.F./50) X 300. So the required number of
streetscape points is 2,360. The streetscape points do not need to be doubled. Please revise the number
of required streetscape points and the required total points. The total required points are 12,895.
Point totals have been revised per comment.
5. For the buffer requirement on the southeastern edge of the site, a minimum of one 2-inch caliper canopy
tree per 25 linear feet of landscape buffer is required. By my calculation, 6 trees are needed.
Additional 6 canopy trees have been added to buffer area per comment. V"
6. The 44 "Indian Hawthorne" shrubs along the southeastern buffer will not count towards meeting the
landscape point requirements as per section 7.6.0 of the Unified Development Ordinance.
The shrub points previously calculated for the 44 Indian Hawthorne shrubs have been removed.
7. Which shrubs are being utilized to meet the buffer requirement of the detention pond? All shrubs are being
counted towards the landscape point requirement.
The shrub points previously calculated for the 44 Indian Hawthorne shrubs have been
removed from the point total. An additional 155 Indian Hawthorne shrubs have been
proposed in an effort to provide an evergreen screen surrounding the detention pond.
Of the total 220 Indian Hawthorne shrubs, only 21 are calculated towards the total site
point requirements.
8. As shown, the berm does not appear to rise above the visible perimeter of the detention pond's finished
grade. It would need to rise to an elevation of 273.5 and then slope back down if using the Skyrocket
Juniper as the buffer shrubs. If not using shrubs toward buffer requirement, the height of the berm would
need to rise to an elevation of 276. The maximum slope is 3:1.
The comment has been addressed. The berm rises to a minimum elevation of 273.50.
9. With right-of-way dedication, the property line will shift back to the edge of the new right-of-way boundary.
As such the streetscape plantings can be moved back, but the plantings will still need to be placed within 50'
of the new property line. As an FYI, plantings can occur within the detention pond itself. Since there is a 20'
P.U.E. along the front of the property, the canopy trees might be better served in the detention pond.
10. FYI, note#16 may need to be changed if planning to put non-canopy trees in the 20' P.U.E.

The top of the weir has been set to 272.37 equal to the 100-year water surface elevation for the
emergency overflow. The 100-year plugged orifice water surface elevation is 272.71', therefore,
the grades surrounding the pond are set at a minimum elevation equal to or greater than the
100-year water surface elevation assuming a plugged orifice plus 6" of freeboard (27321
minimum).
10. Sheet C-08 — We typically do not permit restrictor plates on outfall pipes for maintenance and safety
reasons. Please explain the purpose of the proposed restrictor plate and how you propose attaching it to
the outfall pipe. Additionally, please verify that the"Storm Drainage Calculations" table takes the steel plate
into account.
Details for permanently attaching the restrictor plate are included on sheet C-08. The restrictor
plate is utilized to limit the flow from the orifice in the lower year event storms. The plate is
accounted for in the hydraulic calculations. The restrictor plate controls the maximum
discharge into the pipe. The downstream pipe is in partial flow and does not create a tailwater
effect on the orifice.
11. Sheet C-08 — Please include velocity and sizing calculations for the outfall from the western side of the
property and the emergency spillway in the"Storm Drainage Calculations"table.
Velocity and sizing calculations have been included on Sheet C-08.
12. Sheet C-08 — Junction boxes are required at points of pipe realignment rather than manholes. Please
revise.
All manholes have been replaced with junction boxes. See sheet C-08.
13. Sheet C-08 — Please show the proposed surface treatments on the storm sewer plan in addition to the
erosion control plan.
Proposed surface treatments have been shown.
14. Sheet C-09—Please adjust the meter boxes so they are within the revised PUE.
Comment Addressed. See sheet C-09.
15. Sheet C-09 —The steel waterline encasement pipe is required to have a 16-in. minimum diameter for an 8-
inch waterline. Please revise on profiles as well.
Pipe diameter has been updated. See sheets C-09 and C-10.
16. Sheet C-10—Please verify that the minimum 4-ft cover is provided at approximate Sta. 0+79.
Cover has been verified to be 4ft minimum. See sheet C-10.

of required streetscape points and the required total points. The total required points are 12,895.
Point totals have been revised per comment.
5. For the buffer requirement on the southeastern edge of the site, a minimum of one 2-inch caliper canopy
tree per 25 linear feet of landscape buffer is required. By my calculation, 6 trees are needed.
Additional 6 canopy trees have been added to buffer area per comment.
6. The 44 "Indian Hawthorne" shrubs along the southeastern buffer will not count towards meeting the
landscape point requirements as per section 7.6.0 of the Unified Development Ordinance.
The shrub points previously calculated for the 44 Indian Hawthorne shrubs have been removed.
7. Which shrubs are being utilized to meet the buffer requirement of the detention pond? All shrubs are being
counted towards the landscape point requirement.
The shrub points previously calculated for the 44 Indian Hawthorne shrubs have been
removed from the point total. An additional 155 Indian Hawthorne shrubs have been
proposed in an effort to provide an evergreen screen surrounding the detention pond.
Of the total 220 Indian Hawthorne shrubs, only 21 are calculated towards the total site
point requirements.
8. As shown, the berm does not appear to rise above the visible perimeter of the detention pond's finished
grade. It would need to rise to an elevation of 273.5 and then slope back down if using the Skyrocket
Juniper as the buffer shrubs. If not using shrubs toward buffer requirement, the height of the berm would
need to rise to an elevation of 276. The maximum slope is 3:1.
The comment has been addressed. The berm rises to a minimum elevation of 273.50.
9. With right-of-way dedication, the property line will shift back to the edge of the new right-of-way boundary.
As such the streetscape plantings can be moved back, but the plantings will still need to be placed within 50'
of the new property line. As an FYI, plantings can occur within the detention pond itself. Since there is a 20'
P.U.E. along the front of the property, the canopy trees might be better served in the detention pond.
10. FYI, note#16 may need to be changed if planning to put non-canopy trees in the 20' P.U.E.

The top of the weir has been set to 272.37 equal to the 100-year water surface elevation for the
emergency overflow. The 100-year plugged orifice water surface elevation is 272.71', therefore,
the grades surrounding the pond are set at a minimum elevation equal to or greater than the
100-year water surface elevation assuming a plugged orifice plus 6" of freeboard (27321
minimum).
10. Sheet C-08 — We typically do not permit restrictor plates on outfall pipes for maintenance and safety
reasons. Please explain the purpose of the proposed restrictor plate and how you propose attaching it to
the outfall pipe. Additionally, please verify that the"Storm Drainage Calculations" table takes the steel plate
into account.
Details for permanently attaching the restrictor plate are included on sheet C-08. The restrictor
plate is utilized to limit the flow from the orifice in the lower year event storms. The plate is
accounted for in the hydraulic calculations. The restrictor plate controls the maximum
discharge into the pipe. The downstream pipe is in partial flow and does not create a tailwater
effect on the orifice.
11. Sheet C-08 — Please include velocity and sizing calculations for the outfall from the western side of the
property and the emergency spillway in the"Storm Drainage Calculations"table.
Velocity and sizing calculations have been included on Sheet C-08.
12. Sheet C-08 — Junction boxes are required at points of pipe realignment rather than manholes. Please
revise.
All manholes have been replaced with junction boxes. See sheet C-08.
13. Sheet C-08 — Please show the proposed surface treatments on the storm sewer plan in addition to the
erosion control plan.
Proposed surface treatments have been shown.
14. Sheet C-09—Please adjust the meter boxes so they are within the revised PUE.
Comment Addressed. See sheet C-09.
15. Sheet C-09 —The steel waterline encasement pipe is required to have a 16-in. minimum diameter for an 8-
inch waterline. Please revise on profiles as well.
Pipe diameter has been updated. See sheets C-09 and C-10.
16. Sheet C-10—Please verify that the minimum 4-ft cover is provided at approximate Sta. 0+79.
Cover has been verified to be 4ft minimum. See sheet C-10.

17. Sheet C-11 — The 20-ft curb break allowing runoff to sheet flow into the detention pond and emergency
spillway are proposed to be partially blocked by landscape. This conflicts with the proposed erosion control
mat shown in your Erosion Control Plan. Please revise.
Landscaping has been revised. Erosion Control Sheet has been revised to show solid sod in
this area. See sheet C-11.
18. Drainage Report— Is the detention pond area factored into the "DA-1" analysis in the "Drainage Information"
table?
The 0.41 acre detention pond is accounted for within the 4.28 acre area DA-1. See "HEC-HMS
Models Drainage Area Maps"sheet in Appendix B of the Drainage Report.
19. Drainage Report — In the "Hydrology Results" tables, please clarify how the JA1 maximum flowrate is
obtained.
The flowrate is obtained by using the SCS Curve Number Method and the Muskingum-Cunge
Routing Method run in HEC-HMS. The numbers in the tables do not directly add sue to the
effects of timing as it relates to each watershed.
20. Drainage Report— Please use Appendix C — Table C-10 of the Unified Stormwater Design Guidelines to
obtain the correct roughness coefficient for use in the "Existing Rock Prairie Road Borrow Ditch Information"
table.
The roughness coefficient has been updated from 0.15 to 0.045, which correlates to a grass-
covered, small channel with shallow depth and no rank growth.
Electrical Comments Requiring Immediate Attention
1. Developer provides temporary blanket easement for construction purposes or provides descriptive
easements for electric infrastructure as designed by CSU for electric lines.
The temporary blanket easement has been included.
2. Developer may be responsible for locating easements on site to insure that electrical infrastructure is
installed within easement boundaries.
