Correction in Open Records Request To Trinity Watershed Management.
In my September 22 2014 request below, I had identified Borrow Area D AKA Borrow Area 3.
This should be Borrow Area D AKA Borrow Area 4. For further clarification, this is also located on the Burrescia property
noted in maps south of Elam Road.
Please note this correction in my request.

Subject: Texas Public Information Request - Trinity Watershed Management
Greetings,
This is a request under the Texas Public Information Act.
Records relating to Trinity Watershed Management
Reference: Proposal Documents for Simpkins Remediation- Vegetative Support Layer PBSWM007, File NO. 428D-20,
251D-l. A Notice to all Bidders dated April 25, 2014. I have a 186 page set of records relating to this filing. I do not need
an additional copy.
Clarification: Recently, I was told by officials ofthe Trinity Watershed Management that Borrow Area D, AKA Borrow
Area 3, was originally designated for most if not all borrow soil needs for the Simpkins Remediation and additional
facilities needs ( in conjunction with Borrow Area C south of Loop 12). The statements were that the City of Dallas
determined that due to a stand of trees in Borrow Area D, and the desire to protect these trees, Borrow Area A was
designated to provide soil needs for the Simpkins Remediation.
Request:
I request copies of all communications, including emails and communications reduced to writing, relating to the Borrow
Area D, AKA Borrow Area 3, from the date January 1 2013 to date of this request.
This should include all communications between Trinity Watershed Management and the City Arborist relating to
Borrow Area D.
If any contracts were let and signed for removal of soil from Borrow Area D, please provide a copy of the contract.
If you have any questions, please let me know. If this appears overly broad in scope, we can discuss narrowing the scope
of this request.

Than,
Use this file . I think I was looking at your exhibit incorrectly. I believe your Lake A is theE & F areas in this file. Your lake
A (areas E & Fin the attached) is certainly viable but PK should look at all the utilities in this area.

Than,
Here is where we are with the borrow area. Think we 're pretty close but would like to:
1. Maximize Lake A/B excavatron .
2. Stay away from the Horse Park, or any areas not adjacent to the landfills (to minimize haul distances)
3. Explore Lakes C, D and E, or some variant of them .
Thanks,
Jim

Hi Jim,
Long time no hear. I know that the last t ime we met, we discussed the nearby offsite borrow source needed and how
the sand layer at the Burrescia property (5950 Elam Road) was needed for your project as a total of 450,000 cubic yards
of borrow material was needed north of Loop 12.
We discussed this internally and found a solution for this needed dirt as this borrow source will consist of 3 ponds; 2
new ponds (1 northwest of the western end of Elam Road and 1 on the northern portion of the Burrescia property) and
an enhancement of an existing pond near the entrance into the Horse Park; see enclosed figure. Pacheco Koch revised
the hydraulic modeling for the approved fill permit.
Let me know if you agree with the 3 ponds as the sand borrow source is still there.

Than,
The darker blue area should take care of everything. May be less than thls ... JUSt depends upon how deep we can
go. This is less area disturbed than the fill permit plan .
The lighter area south is if more •s needed .

The index cover page was old but has been updated; see enclosed. I inserted an aerial overlay
to help out for Borrow Area A. Below is the tree count and mitigation inches for each Borrow
Area:
Borrow Area A- 'i94 trees- 3511 inches (Selected due to the lower concentrat ion of trees)
Borrow Area B- 172 trees- 2,329 inches (Large and heavily wooded and near abandoned
United Gas line easement). A lot smaller in size than Borrow Area A.
Borrow Area C- "1·.'34 trees - 5,562 inches (lrrigation Pond) Borrow Area D- 14· trees- 31 S
inches (Burrescia Property- small number of trees but they were all very large pecan trees)

2) Pond C
a) Haul limestone to structural fill area .... add $2.25 per cu. yd. to the fill area #2 quoted unit
price of $2.25 prr cu. yd ...... I 2,200 cu. yds. x S2.25 = $27,450.00 additional cost This is
already paid for in Bid Items 1341, 1342, 1343, and 1344. The Bid Item 1346 is to include survey
staking, compaction, and geotechnical testing. Per Addendum Ill, Note 1115 says "For Bid Alternate 3
(Bid Item 1346- Process/Compact Fill at Structural Fill Locations), payment far this item will include
survey staking, compaction, and geotechnical testing as this will be considered incidental to the bid
item. Additional fill allowance shall be not be stockpiled and bidders are to assume an average haul
distance to the center of each fiJI zone for this additional fill material. All additional fill material shall
be spread by others."
b) Haul approx. I 6,000 cu. yd. of sand from Pond "C" to Fill Area #2 ... .add $2.75 per cu. yd.
= S4.:f,OOO.OO additional cost Per Addendum #1, Note #5 says '7here are 4 identified soil stratums in the
borrow areas; clay, silty clay, limestone, and high quality sands. Landscapes Unlimited would like for soils from
these stratums to be placed in specific areas within the fill areas as they will be spreading of the fill. Due to the
size of the borrow areas and soil stratum depths, the amount of dirt from each stratum of each borrow source
will be substantial sa this will not delay the Contractor's construction schedule. The Contractor will not be
responsible for determining these soil stratums or the associated depths as Landscapes Unlimited will inform the
Contractor on the depth and placement of this material in regions within the fill areas. However, Landscapes
Unlimited requests that the Contractor use best efforts to inform Landscapes Unlimited when contractor observes
a significant change in soil type, stratum, or encounters ground water during eKcavations." If the intended area
for this sand is in another zone not planned, that Fill Zone price will apply.
3) Structural fill a) East parking lor will not be filled to Q l 00. This lot will be filled to a .5% grade from

NOTICE TO ALL BIDDERS
The following constitutes Addendum No. 1 to the Plans, Special Provisions, and Proposal for this
referenced project. This item is provided as clarification and general information, and is hereby
included as part of the specifications for the subject project:
1. Due to the proposed city council approval date of May 14, 2014 for this construction
contract and the City of Dallas's intent to issue a Notice to Proceed (NTP) date within
2 weeks of such approval, the Contracto r shall submit normal Business Inclusion and
Development (BID) forms associated with a city council agenda item as part of their
bid package.
Attached are the forms to be completed as they can be downloaded at:
http://www .dallascitvhall.com/business development/business inclusion forms.htrnl.
Also attached are possible MWBE subcontractors to be considered based on the
scope of work for this project. For any questions about the forms, please contact Lisa
Brough at [email protected] & (214) 670-3335 . If the Contractor does
not meet or exceed the BID goal of 25% for this project, the Contractor will need to
complete the attached MWBE Documentation Form.
2. The bid closing date will remain unchanged, Thursday , May 1, 2014.
3. The structural fill area near the main entrance for South Loop Landfill within Fill Area 2 on
Plan Sheet 13 will require removal of trees not currently identified on the plans as a
tree survey for this area will be done but has not been completed at the time of this
addendum issuance. The winning bidder will be given the completed tree survey in
this area.
No tree mitigation for this area will be needed by the Contractor. Payment for this bid
item includes tree removal (including stumps and root ball) and offsite disposal unless
arrangements are made for on site disposal as no additional payment will be made. All
structural fill areas shall be cleared and grubbed in accordance with the structural fill
requirements for site preparation.
The trees to be removed as part of this project are primarily identified within the
areas identified above. The City of
borrow areas only, with the exception of those
51
Dallas (City) will begin construction on the 1 related project (remediation project Simpkins Remediation [PBSWM0 07]} within the next few weeks. All trees on the
landfill footprint for Elam and South Loop Landfills will be removed as part of that
project. There may be some additional trees to be removed in the identified fill areas
Page 2 of7
Simpkins Remediati on- Vegetative Support Layer (PBSWM007) -Addendum #1
not on the landfill footprint. No payment will be made for additional trees to be
removed for construction access, staging purposes, or not shown on the plans.
As clarification for Bid Items 639A (Remove Trees 6 - 12 inches diameter), 639B
(Remove Trees 13 -24 inches diameter). and 639C (Remove Trees over 24 inches
diameter), payment for these bid items includes tree removal (including stumps and
root ball).
4. The calculated quantity for Bid Item 101 (Clearing and Grubbing) is estimated at 32 .8
acres with a bid quantity of 35 acres as this is estimated for the borrow areas only.
There may be some additional areas to clear and grub in the fill areas .
5. There are 4 identified soil stratums in the borrow areas; clay, silty clay, limestone, and
high quality sands. Landscapes Unlimited would like for soils from these stratums to
be placed in specific areas within the fill areas as they will be spreading of the fill . Due
to the size of the borrow areas and soil stratum depths, the amount of dirt from each
stratum of each borrow source will be substantial so this will not delay the Contractor's
construction schedule. The Contractor will not be responsible for determining these
soil stratums or the associated depths as Landscapes Unlimited will inform the
Contractor on the depth and placement of this material in regions within the fill areas.
However, Landscapes Unlimited requests that the Contractor use best efforts to inform
Landscapes Unlimited when contractor observes a significant change in soil type,
stratum, or encounters ground water during excavations.
6. The estimated amount of dirt to be processed by the Contractor is 5,000 cubic yards a
day as the intent is to place the dirt in front of the earthwork equipment for Landscapes
Unlimited to grade. If the Contractor processes more than 5,000 cubic yards a day (or
more than Landscapes Unlimited can handle), an agreed upon stockpile location will
be given within the fill areas to not slow operations by the Contractor.
7. For Alternate Bid 2 (Bid Item 1345A- Clay Cap for Borrow Areas A, B. and/or D), the
Contractor shall install an 18-inch clay liner using native clay material having a
minimum plasticity index of 25 and compact to 92%-98% at or above optimum
moisture content to all areas under normal water surface elevations. Seal all
permeable areas to restrict seepage from the ponds as no separate payment will be
made .
The City will procure a local geotechnical firm for this testing. The Contractor shall pay
for any retesting fees not meeting these requirements. Payment for Bid Item 1345A
will include unclassified excavation. transport to the fill area, and compaction .
Payment will be based on a ground survey before and after by a Texas Registered
Professional Land Surveyor (RPLS) and a summary report as this will be paid by the
Contractor. Import material can be used and will be paid through delivery tickets.
8. As clarification for General Note #44 on Page 2 of the plans , a trench burn pit will not be
allowed on the landfill footprint due to safety concerns. However, a trench bum pit will
Page 3 of 7
Simpkins Remediation -Vegetativ e Support Layer (PBSWM007) -Addendum #1
be allowed at a minimum distance of 500 feet away from the landfill footprint as the
Contractor will obtain approval from the Texas Commission on Environmental Quality
and Dallas Fire Rescue. The trench burn location must be approved by the Engineer
as a trench burn pit may be allowed near Borrow Areas A. No payment will be made
for removal of additional trees to accommodate this trench burn . The Contractor shall
verify if the trench burn pit is located within the landfill permit.
9. The primary borrow sources (in order of priority) are Borrow Areas A, C, B, and D.
Borrow Area D will only be used is the City decides to not use Borrow Area B or
additional soils are needed. The calculated amount of borrow dirt needed is 625,160
cubic yards as this amount can be obtained from Borrow Areas A and C together. The
City will decide on the borrow areas used for this project as the grading plans for the
borrow areas may change.
10. As clarification for Bid Item 222A (Dewatering for Borrow Area D) -Alternate Bid 1, this
bid item will also apply during the installation of the clay cap until it is completed. No
additional payment will be made for dewatering associated with Alternate Bid 2.
11.As clarification for the cubic yards and bank yards notes shown on the fill area plan
sheets, those 2 numbers reflect the range of dirt volumes that could be brought to that
fill area as the final layout has not been finalized to date. The grading plans are for
information purposes only as Landscapes Unlimited will perform the spreading of the
fill material.
12. This is a closed landfill project as the 40-hour safety trained in accordance with 29 CFR
1910.120 is not required but recommended . Borrow areas are not located within the
landfill footprint.
13. This project will start subsequent to the start of the 1st City project mentioned above but
shall run concurrent with such project. It is recommended that the Contractor follows
51
the same sequencing as the 1 City project.
14.1f there are exposed waste as a result of the Contractor's recent construction activities,
the Contractor shall place at least 2 feet of clay material on top of this area and inform
the Engineer as this will be considered incidental with no separate payment.
15. For Bid Alternate 3 (Bid Item 1346 - Process/Compact Fill at Structural Fill Locations),
payment for this item will include survey staking, compaction, and geotechnical testing
as this will be considered incidental to the bid item. Additional fill allowance shall be
not be stockpiled and bidders are to assume an average haul distance to the center of
each fill zone for this additional fill material. All additional fill material shall be spread
by others.
16. The bid quantities for Bid Items 103 (Unclassified Excavation), 1341 (Transport Dirt to Fill
Area 1), 1342 (Transport Dirt to Fill Area 2) , 1343 (Transport Dirt to Fill Area 3), and
Page 4 of7
Simpkins Remed iation- Vegetative Support Layer (PBSWM007) -Addendum #1
1344 (Transport Dirt to Fill Area 4) will not be renegotiated based on overages or
underage of these bid items.
17. The Engineer (Than Nguyen), or an approved assignee, will sign all offsite waste
manifests.
18. On the plans, there is an existing DWU wastewater easement along Elam Road and a
United Gas easement in Borrow Area B. The Contractor shall pothole and verify the
existence of any existing utility line in both areas as payment will be made through Bid
Item 1652 (Locate Underground Utility Not Under Paving) for each of the 2 lines. Field
verification is needed to determine if existing lines are still present or ever installed.
All bidders shall be required to add the following sentence to the inside of the front cover sheet of
the special Provisions and Proposal with signatures:
