Manager's Comments
Drainage Improvement options Proposed by
Connell Development Co. for Woodside Village
We obtained new cost estimates for constructing the draina.ge
structure from the Skaggs property to the southeast corner of the
Coppell High School property. We asked for estimates based on the
"Blow Form" method suggested by Councilman Robertson. The
estimates exceed'the $345,000 allocated for this project because
we do not have the necessary construction easements to eliminate
all of the trench safety requirements. We are attempting too seeun'!
those easements at this time, and if we are successful, we will be
able to further reduce the cost estimates which we have received.
In regard to the escrow of the $345,000 by COlc1ell, if W~ are not:
able to approve this drainage project on Tuesday, we recommend that
Connell be asked to immediately comply with this requirement,

RE: BOX CULVERT & STORM DRAINAGE IHPROVEHENTS
CONNELL SKAGGS ADDITION
COPPELL, TEXAS
Dear Hr. Koch:
Attached is our 3 page proposal to complete the drainage project. We
made several changes to the original plan, as follows:
1. From Station 23+28.06 to approximately Station 3~~lC we plan to
move the culvert to the east side of the drainage easement.
2. The box culvert will be either as designed utilizing 4000 psi
shotcrete walls to 8' in lieu of class 4 concrete, or 10' wide
box with 4000 psi shotcrete walls to 4' with a ~' arch using
4000 psi shotcrete.
3. The transition at Sandy Lake is to be an extension of the two
36" RCP into the box culvert with a 8" shotcrete wall to seal
the end of the \,,1a11 and the pipe, thus eliminating gabions,
fencing, guardrails, headwalls, and slope protection. The
existing ditch could be graded to an inlet at the beginning
of the box culvert.
Engineering calculations will be submitted if we are successful in
obtaining a contract.
Should you desire, the total project can be done for $350,000 on an
unbonded basis. If so, I believe that terms agreeable to both partic3
can be worked out to assure payment of materialmen and subcontractors.
Cordially,

RE: OUR FILE NO: 26
Comnnell Drainage Agreement
Dear i\1 r. Ratliff:
At the last City Council meeting a question was raised concerning the notat>)].
"waived" which was next to Section 4 of the copy of the Connell Agreement include(1
in the packett (see page 3 of Exhibit "A". You have ask me to search my file f.)r an
answer to the question.
It appears from material found in the council packet of June 23, 1987 (See
Exhibit B) that Connell sent a letter to Wayne Ginn on May 20, 1987 indicating that
they would be immediately constructing the box culve,rt at the same time the higl,
school constructed the culvert on the school propmty. In this letter they requestec
that they not be required to put up the escrow ot letter of credit because of ~heir
intent to start construction immediately. Ginn's letter of June 12, 1987 is in respollfl~
to Connell's letter and indicat.es that "the box culvert issue has been resolved." [I
appears that their Final Plat on Lots I, 2 end 3 were approved "with stipulatiori; (Plea~ ~
see attached letter listing the stipulations)". (see Staff Report in Exhibit B)
Exhibit C is a letter from Connell which explains why they did not follow through
with construction simultaneously with the school construction,.
Since they did not construct the box culvert at. the same time the s~hool
constructed it's section, Connell's oblige.tion to escrow the funds 01' p.~ovide .1 ] ,)tt~~
of credit was restored and remains a valid obligation.
