ENGINEERING COMMENTS NO. 3
1. (Repeat) C -OS The retaining wall needs to be removed from the PUE. The landscaping walls are
shorter than 2' and their location has been approved by Gilbert Martinez.
2. (Repeat) C -07 At the north corner of the building a 45° bend is proposed. You may want
to have a cleanout or manhole at that juncture to prevent clogging.
It looks like a 90° bend at the southwest corner of the building. Notations have been adjusted.
You may want to provide a junction box or manhole rather than a tee to prevent clogging. Junction
box added at this location
3. (Repeat) C -08 _A single public waterline should be extended along the northern property line within a
PUE. The fire line, domestic waterline, irrigation line, and meters may then be extended off of a single
tap of this main. Please call to discuss.
The irrigation line should come off of the new public waterline rather than the fire hydrant lead.
Irrigation tap has been relocated.
There should be a TS& V where the 6" ties into the 18" waterline. TS &V added.
Please label the isolation valve on the fire line and place it at the edge of the PUE. Valve has been
labeled and re- located.
4. (Repeat) C -08 _It looks like the waterline and electrical infrastructure will conflict in the 10 -ft PUE. Please
provide additional width for the PUE to support the waterline and meters. Io,I�0
Please show the rerouted electrical lines and proposed PUEs per CSU's comments. Plans are a.a
adjusted to reflect conversations with Gilbert Martinez. 4:

7. (Repeat) C -b You may want to add some hay bales within the bar ditch for additional erosion control.
The silt fence (as well as hay bales within the ditch) should be downstream of all construction
activities. Silt fence and hay bales relocated to include SS construction.
8. (Repeat) Drainage Report _The BCS Unified Stormwater Design Guidelines specifies that the Rational
Method must be used for smaller developments such as this one. As discussed with Erika, the city will
allow the TR55 method for this project.
9. (Repeat) Drainage As previously discussed, an offsite drainage easement from the site to the primary
channel will need to be secured prior to site plan approval. The property owner is working to provide this
document.
10. (Repeat) Cost Estimate The Cost Estimate should only include public infrastructure.
Please revise to reflect the pressure rated sanitary sewer pipe and TS &V. See revised cost
estimate.
11. (Repeat) FYI The plat must be filed and cross access easement dedicated prior to site plan approval.
Noted
12. Please submit offsite PUE dedication applications for the water and electrical infrastructure. Will be
submitted by the surveyor at a later date.

ELECTRICAL COMMENTS NO. 2 REQUIRING IMMEDIATE ATTENTION
1. Developer provides temporary blanket easement for construction purposes and provides descriptive
easements for electric infrastructure as designed by CSU for electric lines. Will be submitted by the
surveyor at a later date.
2. Developer may be responsible for locating easements on site to insure that electrical infrastructure is
installed within easement boundaries. Noted.
3. Transformer location shown on site plan does not provide clear working access required by CSU. The
transformer will need to be relocated next to or possible within the dumpster enclosure if clearance is
available in this area. If clearance is not available the transformer will need to be relocated to a front
parking median. Transformer relocated to other side of dumpster.
4. If the transformer is relocated to a front parking median then the electric service will need to be located
on the south side of the building. CSU will not pull electric service from the front, down the side and
around to the back of the building. N /A.
5. If applicable, the following easements will be required:
I) If transformer is relocated to the front of the property CSU will require 20' PUE's covering the primary
electric route as designed by CSU. N /A.

from PUEs. All private utilities have been removed from the PUEs.
2. The FDC appears to be in the middle of the proposed sidewalk. Please move to pervious
area. Symbol adjusted on plan to show correct location
3. (Repeat) All water meters need to be located adjacent to the edge of the PUE (within the
PUE). Water meters moved to the edge of the PUE.
4. Site Plan — Please add a note regarding the property being located within the Harley Water
Impact Fee Area. Please see site plan note #19
5. Site Plan — Please label proposed PUE for waterline with fire hydrant. Proposed 15' PUE
now labeled.
6. Site Plan — Please label sidewalk within PUE and provide a note stating that the sidewalk
shall not be part of the foundation and is removable if necessary for maintenance of utilities
within the PUE. See site plan note #20, referenced on plan
7. Site Plan — Our system shows the following easements on the property:
a. 25 -ft PUE (Vol.961, P.715) Corrected
b. 20 -ft City of Bryan ROW (Vol.30, P.51) Shown
8. Site Plan — Please label the FDC. Now Labeled
9. C -03 — What is the 14'x18' section of pavement at the northwest corner of the building? A
proposed play area. It will consist of flatwork with curb containing soft play yard material. It
will not include any permanent structures within the PUE. Referenced w/ detail.
10. C -05 — The retaining wall needs to be removed from the PUE. The retaining wall has been
reduced to less than 2' tall and is called out on the plan as a "landscape wall".
11. C -05 — Revise the label the reads "ME ? ? ?" in the southwest corner of the detention pond.
Revised to include the existing elevation that should be matched in that location.
12. C -05 — Please provide additional grading information around the detention pond including
top of wall elevations, pilot channel flowlines, and pond slopes. Additional information is
now included.
13. C -07 — At the north corner of the building a 45 bend is proposed. You may want to have a
cleanout or manhole at that juncture to prevent clogging. Cleanout added.
14. C -07 — Please show and label the roof drainage system. This will be shown on the MEP
plans that will be included in the building review.
15. C -07 — How does the 12 -inch HDPE from the rain barrels tie into the outfall? A blow up
view has been provided. The line is not connected to the outfall but empties out behind the
outfall at the rip rap area.
16. C -07 — Please provide a detail of the detention basin and curb break for the pond.
Detention basin detail added on sheet C -07; Curb break detail added on sheet C -11.
17. C -08 — A single public waterline should be extended along the northern property line within
a PUE. The fire line, domestic waterline, irrigation line, and meters may then be extended
off of a single tap of this main. Please call to discuss. The domestic and fire line have been
combined and tap into the main line at the front of the property. The irrigation tap remains
as this location makes the most sense for landscaping purposes.
18. C -08 — It looks like the waterline and electrical infrastructure will conflict in the 10 -ft PUE.
Please provide additional width for the PUE to support the waterline and meters. Based on
the plans provided by Gilbert Martinez, the electrical line will be located on the far side of
the easement. As only a 2' clearance is required by electrical, there will be enough width in
the 10' PUE without conflict.
19. C -08 — Please provide a plan and profile drawing for the proposed public waterline. Profile
now added.
20. C -08 — The private sanitary sewer service line should be at a minimum 1% slope. The pipe
has been increased to an 8" line, which allows for a 0.5% slope. A 0.6% slope will be used -
velocity in the pipe with this slope will be 2.65 fps.
21. C -08 — The sampling well and grease trap were previously labeled incorrectly. Please show
and label their revised location. These will be shown on the MEP plans that will be
submitted for building permit.
22. C -08 — Please follow TCEQ Chapter 217 guidelines for water and sanitary sewer separation
distance of Tess the 9 -ft horizontally. Also, revise Utility Note #9. Additional notation added
in the profile regarding the requirements for lines closer than 9'. Note #9 revised.

flowing to the south.
24. C -09 — Please show the existing 8 -inch sanitary sewer to the south. Included
25. C -09 — The sanitary sewer line needs to be at least an 8 -inch to for future development.
The public SS extension is 8".
26. C -09 — Please label the flowlines of all pipes coming into or out of a manhole. Profiles
adjusted to include existing flowlines.
27. C -10 — You may want to add some hay bales within the bar ditch for additional erosion
control. Additional hay bales have been added.
28. C -11 — It does not look like details for all the items that were referenced Sh. C -07 were
included on this sheet. Please include a detail for the rain barrels, too. These details are
now included.
29. C - 11 — Which sheet shows where Sections A - A and B - are located? Now referenced on
sheet C -05.
30. Drainage Report — The BCS Unified Stormwater Design Guidelines specifies that the
Rational Method must be used for smaller developments such as this one. The UDO states
that the rational method may not be used for detention design. Also, because the TR -55
method is more accurate, we understood it to be allowed for all sites.
31. Drainage Report — The curve numbers don't seem to correlate to Table C -6 and seem high.
Please clarify and /or revise. We have referenced the curve numbers provided in TR -55.
32. Drainage — As previously discussed, an offsite drainage easement from the site to the
primary channel will need to be secured prior to site plan approval. The site owner is
currently pursuing this easement.
33. Drainage — This development was partially included in the original Southside Plaza
development drainage calculations. We also view this as a new phase of that development
and will require that existing issues with site drainage and detention for the original phase of
the project be addressed at this time. The owner has taken this under consideration and
will deal directly with the city regarding this issue.
34. Cost Estimate — The Cost Estimate should only include public infrastructure. Cost estimate
revised.
35. Cost Estimate — There is more than 20 LF on sanitary sewer line proposed across the front
of the property. Cost estimate revised.
36. Water /Sanitary Sewer Report — Please clarify how the water and sanitary sewer demands
were calculated and how the water meters were sized. Water and SS report revised.
37. Fire Flow Report — Please reference the proposed square footage of the building in the
letter. Fire flow letter revised.
38. Fire Flow Report — The minimum required fire flow after the 50% reduction for sprinklered
buildings is 1500gpm. Fire flow letter revised
39. Fire Flow Report — Please provide actual flow test data, if possible. Fire flow letter revised
