West Sandy Lake Road Project
To:
The following is our response to the comments on the schematic submittal that we received
at our meeting on February 28, 2003. We have divided the responses into two categories in
order to eliminate some redundancy. The General Comments section addresses comments
that are recurring throughout the plans and comments that can be addressed with a similar
response. The Individual Comments section addresses any comments that are specific to a
particular sheet in the plans or comment compiled by the City of Coppell review staff.
General Comments
1. Several sheets have comments about sidewalks on the north side of Sandv Lake
Road from S.H.121 to Coooe" Road North.
The sidewalk in this area will be eliminated from this project per discussion at our
February 27, 2003 meeting. This will also eliminate any conflicts of the sidewalk
with the transmission poles on the north side of the road.
2. Several comments were made about sidewalks adiacent to curbs or over/a DinG
recessed curb inlets.
Every attempt will be made to move sidewalks at least two (2) feet from the back of
curb for the entire length of the Sandy Lake Road project. In cases where it is
impractical, the sidewalk width adjacent to the curb will be a minimum of six (6)
feet. Sidewalks will be routed around the inlets.
3. At every left turn median throUGhout the oroiect. a comment indicatinG the use of
oavers was made.
The medians will be enhanced according to the City standards in conjunction with
the landscape/streetscape design. Stamped concrete will be used at all locations
in lieu of pavers.
Page 1 of 16
4. Several comments reaardina the relocation of fire hydrants were made throuahout
the plans and written comments.
Fire hydrant relocation as well as many other utility conflicts will be addressed
during the preliminary design phase of the project.
Individual Comments
Sheet 5.
1." The H. T. ArdinQer. Jr. and Jose A. Esteve tracts are now Amberooint
@Coppell L.L.C.
We will reflect this change in our preliminary plans. We will need to obtain
the construction plans for this development in order to coordinate any
interface of the two projects.
Sheet 6.
1. The Charles Bandemer tract is now Coppell Bible Fellowship.
We have the plat and construction plans for this property and we will
incorporate the proposed improvements for this property (currently under
construction) in our preliminary design phase.
~ Will a sidewalk easement be required at the Sowell Property?
The location of the trail in this area will be further evaluated in the
preliminary design phase and any easement needs will be determined later
in the design process.
;i, Is it State Road or Freeport Parkway?
It is our understanding that Freeport Parkway is the appropriate name for
this road.
4. Is it necessary to acquire 29 SQ. FT. for lot 32 - WindinQ Hollow Lane?
In the schematic submittal we included any possible right-of-way takings
that we had identified. During the preliminary design phase we will evaluate
the necessity of such right-of-way takings
5. Why not acquire more riaht-of-wav to the south of Sandy Lake Road - iust
east of Coppell Road South?
The alignment throughout this area dictated the right-of-way takings. The
alignment was set to limit the impact on trees and the TXU transmission line
poles that are located on the south side of Sandy Lake Road in this area.
Page 2 of 16
---l
6. On the olans there were some hiGhliGhted riGht-of-way takinGS with a
Guestion mark for four (4) oarcels in Oakbend Addition.
We are unsure of the question regarding this matter. Right-of-way will be
needed in this area but the right-of-way shown does not interfere with any
fences or permanent improvements excluding landscaping.
L The Thomas McHale orooerty is marked throuGh with Coooell written beside
it.
This will be changed to reflect just the City of Coppell as the property owner.
Sheet 7
1. Per our meetinG on February 27. 2003 there is oossibly a tract of land
owned by Joan White iust to the north of the GTE orooerty.
The property in question will be researched and evaluated by TNP.
Sheet 8
1." The "6 Lane Divided" roadway section shows 39' for the 3-lane width and 8'
minimum for the back-of-curb to riGht-of-way width. The Coooell standard
roadway section shows 37' for the 3-lane roadway width and 10' minimum
for the back-of-curb to riGht-of-way width.
The additional 2' was added to the outside lanes in order to accommodate
an on-road bike lane per a meeting with City of Coppell staff on June 19,
2001.
2. The "4 Lane Divided" roadway section shows 27' for the 2-lane width and
10' minimum for the back-of-curb to riGht-of-way width. The Coooell
standard roadway section shows 25' for the 2-lane roadway width and 12'
minimum for the back-of-curb to riaht-of-way width.
The additional 2' was added to the outside lanes in order to accommodate
an on-road bike lane per a meeting with City of Coppell staff on June 19,
2001
3. The "4 Lane Divided" roadway section shows 8" of reinforced concrete. The
Coooell standard roadway section shows 7" of reinforced concrete.
This was determined at a June 19, 2001 meeting with City of Coppell staff
based upon information and recommendations in the geotechnical report by
CMJ Engineering, Inc.
4. The "4 lane Undivided" roadway section shows 54' for the 4-lane width. The
Coooell standard roadway section shows 49' for the 4-lane roadway width.
The additional width was added to the outside lanes in order to
Page 3 of 16
accommodate an on-road bike lane per a meeting with City of Coppell staff
on June 19, 2001
5. The "4-lane Undivided" roadway section shows 8" of reinforced concrete.
The Coooell standard roadway section shows 7" of reinforced concrete.
This was determined at a June 19, 2001 meeting with City of Coppell staff
based upon information and recommendations in the geotechnical report by
CMJ Engineering, Inc
6. Two of the roadway sections show lime stabilized subarade and two of the
sections show cement treated subarade. both at an aoolication rate of
39#/S. Y. Were these treatments and rate of aoolication determined by soil
testina?
Yes, the Geotechnical report recommended the use of both lime and
cement treatment. Lime stabilization west of Oakbend Drive and cement
stabilization east of Oakbend Drive was recommended by CMJ
Engineering, Inc.
Sheet 9
L. Need to verify ownershio of the transmission towers alona the north side of
Sandy Lake Road. They are labeled as TXU-they may belona to the Brazos
Electric Power Corooration.
TNP will verify the ownership of these poles as part of the utility
coordination.
Sheet 10
L. Transition rate-lane droos?
The temporary transition was designed based upon design speed and
transition rates recommended by AASHTO. These will be analyzed more
closely during the preliminary design phase. The permanent improvements
to the west of Royal Lane include a free right turn lane from Sandy Lake
Road to Royal Lane based upon our understanding of the City's desired
configuration.
2. Is the amount of asohalt shown in the transition necessary-could it be less?
The temporary transition was designed based upon design speed and
transition rates recommended by AASHTO. These will be analyzed more
closely during the preliminary design phase.
3. Will Royal Lane extend to the north of Sandy Lake?
It is our understanding that Royal Lane to the north of Sandy Lake Road will
not be constructed with this project. However, TNP's design of the
Page 4 of 16
intersection will allow for the future extension of Royal Lane to the north
without the requirement of any significant reconstruction or pavement
removal.
4. A note on the olans indicates to move the inlet on the north side of the
intersection with Royal Lane to the west to accommodate the future
extension of Royal Lane to the north.
This inlet will be relocated.
5. A comment on the olans indicates that 250' left turn storaae lenath is "Iona".
This storage length was extended beyond the City's standard due to
recommendations from the Traffic Study by Lee Engineering.
6. A note on the orofile asks if there is a oroblem with a 3' cut by the TXU oole.
The allowable amount of cut near the poles will be coordinated with the
respective owners of the poles. Adjustments to the profile will be made
accordingly.
Sheet 11
L. Label the transmission tower #3 shown at Station 16+45 Lt.. It is located
within the oroDosed sidewalk.
The proposed sidewalk on the north side of the Sandy Lake Road in this
area is being eliminated from the scope of the project.
2. The manhole at Station 17+00 Lt. is located within the orooosed curb. Will it
need to be relocated instead of adiusted?
The conflict with the manhole will be addressed. An offset manhole may
need to be installed to avoid a conflict.
3. Show the Drofile of the existina 12-inch water line. The fire hYdrant located
at Station 16+00 will need to be removed and relocated.
The approximate location of the 12-inch water line has been shown based
upon plans provided by the City. Additional detailed plan and profile as-built
drawings may be needed from the City in order to help identify the vertical
location of this line. The fire hydrant relocation will be addressed in the
preliminary design phase.
4. Ten-foot left turn lane width does not meet code. What about MTP?
The lanes will be re-configured to have an 11' left turn lane.
5. What about 70-foot riaht-of-way?
Page 5 of 16
It is not clear what is meant by this comment.
Sheet 12
1." The orooosed drive shown at Station 19+30 Rt. mav no lonaer be reauired.
Need to coordinate with the Amberooint development.
This will be addressed in preliminary design.
2. Label the transmission tower #4 shown at Station 22+10 Lt.. It is located
within the oroposed sidewalk.
The proposed sidewalk on the north side of the Sandy Lake Road in this
area is being eliminated from the scope of the project.
3. There is less than 6 inches of cover between the bottom of the proposed
culvert and the tops of the existina a-inch sewer and 24-inch water lines.
Thev will need to be adiusted. The proposed culvert is constructed over a
valve on the existinq 24-inch water line.
The drainage design shown only represents a schematic level design and
will be evaluated in more detail as part of the preliminary design phase in
order to determine the best place for culvert crossings and culvert depths.
4. Does the 12-inch water line conflict with the oroposed culvert? There is a
fire hvdrant on the 12-inch water line at Station 22+00 that will need to be
removed.
The drainage design shown only represents a schematic level design and
will be evaluated in more detail as part of the preliminary design phase in
order to determine the best place for culvert crossings and culvert depths.
The fire hydrant relocation will be addressed in the preliminary design
phase.
5. Where does the 24-inch waterline turn south?
At Station 18+32+/- the 24-inch water line turns to the south.
Q" A question was asked about anv trees in the median beinq saved.
It was determined that any trees that fell within the median would most likely
be lost. Therefore, they were shown as trees that would be removed. As
discussed in the meeting on February 28, 2003, it is believed that these
trees have already been removed by the Amberpoint Development. TNP
will confirm what trees have been removed.
Sheet 13
1." Northpoint Drive will intersect Sandv Lake Road at aoproximate Station
Page 6 01 16
27+50 Rt.. This needs to be coordinated with the Amberooint development
and a median openinq will be reGuired on Sandy Lake Road. The road
should be completed within 60 days.
This development and its associated improvements will be included with the
preliminary design phase of the project.
2. There is an existinG Gravel drive on the north side ofthe street that serves
as the primary access to an existinG mobile home. Show this drive and
provide access from the new pavement.
The property owner at this location has not allowed our survey personnel
access to obtain detailed survey information. We understand that the City is
seeking permission from the owner to access the property.
3. A comment on the plans states to move inlet at approximatelv Station 26+80
left to keep from relocatinG fire hydrant.
This will be addressed in the preliminary design phase.
Sheet 14
1" Where does the low point fall at the curb inlet at approximate Station
28+90?
The curb inlet locations will be evaluated more closely in the preliminary
design phase.
Sheet 15
1" On the plans there is a comment about relocatinG the proposed drainaGe
system out of median in order to save trees.
The existence of the trees will be verified and the location of the proposed
drainage system will be re-evaluated in the preliminary design phase.
Sheet 16
1" Show the existinG Gravel drive on the north side of the street. Will an
approach be provided for this drive?
The gravel drive will be shown on the plans and access will be provided.
2. The mark-up plans show a comment for a stamped concrete band around
the intersection with Freeport Parkway.
This intersection will be designed with the appropriate pavement
enhancement according to the City's standards and the
LandscapelStreetscape plan.
Page 7 01 16
Sheet 17
L The mark-up plans show a new median openinG servinG the Droperly to the
south.
It is our understanding that this median opening is intended to serve the
Coppell Sible Fellowship Church. We will include this median opening in
our design and show a left turn lane for westbound traffic with as much
storage as possible. Also, any formal drainage system from the Coppell
Bible Fellowship Church will be addressed in the preliminary design phase.
Sheet 18
1. The left turn storaGe lenGth for Oakbend Drive is shown as 50'. The Coppell
standard minimum for low volume streets is 60'.
The length of the left turn storage can be lengthened by shrinking the
median just to the east. This entire median will be re-configured to
maximize the left-turn storage for both Oakbend Drive and Coppell Road
North.
2. The desiGn speed for a 4-lane divided roadway is 50 MPH and the minimum
radius for a horizontal curve is 800'. The curve at Station 51+45.90 has a
desiGn speed of 40 MPH and a horizontal curve lenGth of 565'.
Due to physical horizontal constraints both the minimum design speed and
curve length were not met. Superelevation was used to increase the design
speed but the 50 MPH minimum could still not be achieved. This issue will
be discussed further between TNP and the City, prior to completing the
preliminary design.
3. The top of curb left and riGht are shown at the same elevation. What about
the superelevation?
For ease of display on the schematic plans, only one curb line was shown.
Depending on the final design, the appropriate curbs will be shown
accurately in the profile.
4. There is a note 27" RCP on the Dlans.
TNP is unsure about this comment. There is an existing 27" RCP shown in
the plans but it is unclear what is meant by this comment.
5. The mark-up plans indicate extendinG the sidewalks for both Oakbend Drive
and Branchwood Drive.
These sidewalks will be extended as noted.
6. A note on the plan indicates usinG a recess curb inlet alonG the norlh side of
the median instead of a Grate inlet.
Page 8 01 16
------------- ----- --- ----- ---- ----------- ------
-- ------------ --- ----- -------- -- - --- ------ -
TNP will evaluate the inlet options along the medians.
This median will be redesigned to optimize the left turn storage for both
Coppell Road North and Oakbend Drive.
Sheet 19
J.." There is not an ADA ramp shown on the west sidewalk alonG the
intersection of Coppell Road north.
The intersection and sidewalk/trail configuration will be re-evaluated. ADA
ramps will be provided where needed at the intersection.
g, The left turn storaGe lenGth for Coppell Drive North is shown as 135'. Is
135' of left storaGe at Sta. 53+00 adeGuate in lenGth for the traffic volumes
at this intersection? Does this need to be increased to 150'?
3. The 12' tall fence alonG the north side of Sandy Lake Road from station
55+00 to 59+00 is sittinG on top of 10' to 12' stacked retaininG wall. This is
not labeled or shown in the cross-sections. Special care will need to be
taken durinG construction to maintain the inteGrity of the wall.
This wall will be completely evaluated during the preliminary design of
Sandy Lake Road. TNP now has the plans for that retaining wall and will
use those to evaluate the impacts that the proposed changes to Sandy Lake
Road may have on the existing wall.
4. What are the limits of the a-inch water that is abandoned? It is not labeled
as abandoned on sheet 20.
TNP will check the existing plans for the utilities within this area for
accuracy.
5. At what anGel does Coppell Road tie into SandY Lake Road?
The angle at the intersection of the centerlines for Coppell Road North and
Sandy Lake Road is approximately 90 degrees.
6. The mark-up set of plans show to remove the islands in the intersection of
Coppell Road North and SandY Lake Road.
The intersection will be redesigned to eliminate the islands by reducing the
radii of the curb returns. Median noses will also be redesigned to allow for
traillsidewalk crossings.
7. There is an existinG drainaGe system from a Cul-de-sac iust east of Coppell
Road North that is not proposed to be collected.
Page 9 of 16
This system will be addressed in the preliminary design phase.
Sheet 20
L. Show the 8-inch water line in the orofile.
The locations of existing utilities will be confirmed and reflected in the plans.
2. A note on the orofile reGuests that the road be raised in elevation from
station 57+00 63+00.
This may not be possible due to sight distance calculations and K values
associated with the vertical curves. During the preliminary design phase,
TNP will evaluate adjusting the roadway profile where possible.
3. A comment in the olan asks for the trail to be moved away from the curb.
By moving the trail away from the curb, the retaining walls in this area may
increase. However, the trail may be moved away from the curb by reducing
the width form 10 feet to 8 feet without increasing any retaining walls. This
will be evaluated more thoroughly in the preliminary design phase.
Sheet 22
L. The too of curb left and riaht are shown at the same elevation. What about
the suoerelevation?
For ease of display on the schematic plans, only one curb line was shown.
Depending on the final design, the appropriate curbs will be shown
accurately in the profile.
2. Where is the adverse crown? Make sure that it is not in the flatter section of
the vertical curve. Prefer it not to be in the vertical curve at all.
It appears that in the flatter portion of the vertical curve, the cross slope on
the south side of the road is almost at its 2% superelevation. However, this
will be evaluated more closely in the preliminary design phase.
Sheet 23
L. The desiGn soeed for a 4-lane divided roadway is 50 MPH and the minimum
radius for a horizontal curve is 800'. The curve at Station 69+20.37 has a
desiGn soeed of 45 MPH and a horizontal curve lenGth of 570. 76'
Due to physical horizontal constraints both the minimum design speed and
curve length were not met. Superelevation was used to increase the design
speed, but the 50 MPH minimum could still not be achieved. This issue will
be discussed further with the City prior to completing the preliminary design.

2. Are crosswalks required at Coppell Road South?
Yes, and they will be provided with a new configuration of the intersection.
3. A note on the plans state that we may not encroach the trail in a common
space easement.
The trail location in this area will be revised depending on the coordination
between the City and the HOA's in this area.
4. Another note requests flush medians with stamped concrete and the ramps
to be relocated.
The intersection will be reconfigured to show the City's recommendations
during the preliminary design phase.
Sheet 25
L. Show the 8-inch sanitary sewer in profile
The locations of the existing utilities will be confirmed and reflected in the
plans.
2. Do Gas substation relocation issues exist?
All efforts will be made to avoid any conflicts with Lone Star Pipeline.
3. The plans show a need for a drive access to the Gas sub-station.
Access will be provided for the gas sub-station.
4. A comment was made about conflicts with the 24" Qas main that crosses the
proiect near Station 84+25.
This item was discussed during the February 27, 2003 meeting and TNP will
adjust the grades of the roadway in order to avoid any conflict with this gas
line._
Sheet 26
L. Plan comments indicate movinQ an inlet location to the west and a auestion
about a new driveway at approximate Station 90+00.
Inlet locations will be re-evaluated and placed in locations which minimize
impacts on properties. On this sheet and several that follow the drainage
pipes were not shown in the paving sheets. They can be found in the
drainage sheets later in the plan set. The new driveway will be added to the
plans.
Page 11 of 16
Sheet 27
L. Is the left-hand turn storaae lenath of 150' excessive for a turn into
Whisoerina Hills Drive?
The left turn storage length is based on the storage length recommended in
the Traffic Study by Lee Engineering.
2. Prooosed riaht-of-way on north side of road (Station 91 +00 to 92+00) -
reo/at as current - may not be the best solution.
TNP is not aware of any re-platting of this property but will obtain copies of
the latest filed plat for future design.
Sheet 28
L. Is a 60' storaae lane sufficient for Shadydale Lane?
A 60' storage length is the City standard length and the Traffic Study by Lee
Engineering did not indicate that additional storage was required.
2. Do crosswalks need to be orovided at Shadydale Lane for the school?
TNP will investigate this issue and discuss with the Landscape/Streetscape
consultant for this project.
3. Plan comments indicate that the trail is on private orooerty east of Georaian
Drive.
TNP will investigate the property information with regards to the trail
location. Any adjustments needed in the trail alignment will be determined
in the preliminary design phase.
Sheet 29
1. The orofile does not exist for the road into "Everybody Fits".
This is an existing access drive, not a public street, and will be profiled in the
preliminary design phase.
2. Does the 10' bike oath need to stay within the riaht-of-way at aooroximate
Stations 102+00 to 103+00?
TNP will investigate this with the Landscape consultant during the
preliminary design for Phase II.
~ The mark-uo o/ans indicate oossibly relocatina the Verizon driveway to
correlate with the drive on the north side of SandY Lake Road in order to
orovide common median openina that would serve both drives.
Page 12 01 16
Suzan Taylor-
TNP will look at some options that would satisfy this request and investigate
the implications associated with this change. At that time the City and TNP
can approach Verizon concerning the impacts.
Sheet 30
L. More detail is needed for the four drives shown on this sheet since there is
no profile.
The preliminary design will include profiles of all drives intersecting Sandy
Lake Road.
.f.." Need to label "end of existinG concrete" at approximate Station 110+10.
This will be shown more clearly on the preliminary plans for Phase II.
3. The plans indicate movinG an inlet at approximate Station 106+75 for a
future drive.
The inlet will be adjusted as indicated.
Sheet 31
L. How much of the existinG concrete roadway will remain?
The limits of demolition will be further defined with the preliminary design.
2. There are some construction lines and notes reGardinG the layout of the
intersection with Denton Tap road on plans.
The recent improvements on the east side of the existing intersection are
not reflected in this set of plans. The intersection work has since been
completed and TNP will survey this intersection prior to completing
preliminary plans for Phase II to see that the intersection functions as
desired by the City.
3. The 10' Bike Path note is circled and Guestioned on this sheet in the mark-
UP set of plans.
TNP is not sure what is meant by this comment.
Sheet 38
L. Why show the Ground elevation on the left?
This will be re-evaluated during the preliminary design phase.
2. Show top-of-curb from the northbound lanes.
Page 13 of 16
This will be shown in the preliminary plans.
Sheet 39
L Are anv fill or slope easements reauired?
Slope easements will be identified with preliminary design.
Sheet 40
L Show existina arade information from field data and not from A-B.
We are assuming that "A-B" stands for as-builts. TNP surveyed this area
and the survey information is shown.
Sheet 41
L Existina access to future Freeport Parkwav north of Sandv Lake -Iav-down
curb or leave out?
The existing drive on the north side will be provided access but the future
construction of Freeport Parkway to the north will require the removal of
some curb along the north side of Sandy Lake Road.
2. Mav need comer-clip at the southwest comer of Freeport Parkwav.
A corner clip shown as proposed R.O.W should be adequate but TNP will
check to see what was actually dedicated.
3. Show riaht-of-wav dedicated bv Amberooint Development.
The new right-of-way will be reflected in all future design phases of this
project.
Sheet 42
L Oakbend Drive - inlets to be adiusted to an adeauate depth?
During the preliminary design phase the details of the drainage design will
be addressed.
2. Low K values are shown on all intersections.
Since these intersections require slower traffic movements and less sight
distance, lower K values were provided in order to minimize the amount of
reconstruction required on these side streets.
Sheet 43
L Do we real/v want to raise the elevation of Coppell Road North - is this
because ofthe 24-inch water line?
Page 14 01 16
Since this intersection is signalized and the design speeds could be
maintained throughout the intersection, the vertical curves need to be
conducive to the higher speeds. This problem is compounded by the
superelevation of Sandy Lake Road at this intersection.
2. The plans show some comments reoardino the raised medians and the
crossino of Sandv Lake Road with the bike trail.
The intersection will be re-configured to eliminate the raised medians. The
bike trail will also be revised for ADA compliance.
Sheet 44
L. The mark-up plans show a comment on Bricknell Lane reoardino an ADA
route across the intersection.
This will be addressed.
Sheet 45
L. Will this create a future profile problem such as Coppell Road North. except
too hiah?
The final design of Sandy Lake Road will be coordinated with the design of
Coppell Road South.
2. The mark-up plans show a comment reoardino the raised medians at
Coppell Road South.
This issue will be addressed as described earlier. (See comment number 4
from Sheet 23)
Sheet 46
L. The plans have a comment reoardino connectino the sidewalks at Forrest
Bend.
These sidewalks will be connected.
Sheet 47
L. Summer Place - are the orades shown too dramatic considerino that the
inlets are proposed iust upstream on Sandv Lake?
The effects of the drainage on Summer Place will be re-evaluated in the
preliminary design phase and the grades adjusted as necessary to improve
the approach to Sandy Lake Road.
Sheet 48
L. What can be done to discouraoe anv cut-throuoh from Oak Trail to the
concrete drive to the west?
Page 15 of 16
This driveway is a residential driveway that leads to a house. It does
connect back to Sandy Lake Road but is no different than it is today and
should not be conducive to cut-through traffic since there is not a proposed
median opening for Oak Trail on Sandy Lake Road.
Sheet 61
1" Future Northooint Drive aooears to tie into Sandv Lake near Sta. 27+50.
Need to verify location. There is a recessed inlet that may need to be
relocated.
The Northpoint Drive will be located and any proposed improvements will be
adjusted accordingly.
2. There are several existina water lines and valves in this area that are not
shown on the olans.
The existing utilities will be verified and shown accordingly.
Sheet 61 - 70
1" Does Coooell allow the use of RCP storm drain with a diameter smaller than
21 inches?
It is our understanding that for inlet leads 18" RCP can be used.
Sheets 56 - 61
1" The laraest inlet size shown in the Coooell standards is 14 feet. Does
Coooell allow for 20-foot inlets?
It is our understanding that 20-foot inlets are acceptable for use.
Sheet 67
1" The 24" water line at Sta. 62+00 may need to be lowered.
TNP will evaluate this during design.
Sheet 74
1" Two existina sanitary sewer manholes on the north side of the street near
Sta. 101+00 are not shown.
In the set of mark up plans two sanitary sewer manholes are shown on the
north side of the road. TNP will verify that there are no other manholes.
