Stonn Drainage:
It is understood that the Leslie Tract plans to drain storm water onto Billingsley's
property to the north. The Leslie Tract development shall:
1. Detain all developed drainage flows to match current undeveloped
conditions.
2. Release concentrated detained drainage flow, calculated to be 85 efs, at
the northeast corner ate Leslie Tract (see attached Exhibit A).
3. It is reeogmized that temporary grading will be required an the
Billingsley property to accommodate that flow, but note that a permanent
easement is not anticipated. You shall comply with the following:
a. Construction will be for grading purposes only. You will
provide appropriate erosion control and restoration of disturbed
ProPertY
b. The temporary grading will follow the limits of grading and the
amount of grading as shown on the Pacheco Koch Consulting
Engineers plan dated September 09, 2011 (see attached Pacheco
Koch plan).

on January 31', 2012, subject to force majeure or delays caused
by the City of Coppel I.

Record Survey of the improvements on Billingsley's property
and upstream 50 fed within your property.
4. Provide an appropriate storm water quality control device via a wet
detention pond for all drainage from gas stations and other individual
developments on the property.
Wastewater;
The City of Coppell is requiring the wastewater flow generated from the Leslie
Tract and from Billingsley Company's property be combined into one (1)
wastewater line fa one (1) bore crossing across Belt Line Road in lieu of two (2)
separate bore ‘rossinp. It is anticipated that Billingsley's property will generate
approximately 1250 GPM and is to discharge into the City of Coppell system in
Belt Line Road According to your Engineer's calculations, it is anticipated that
the Leslie Tract will generate approximately 536 GPM, and is also to discharge
into the same City of Coppell system in Belt Line Road. The Leslie Trace will
retain the right to any excess sanitary sewer capacity above the combined 1250
GPM from Billingsley and 536 GPM from the Leslie Tract projected to flow
through the proposed 15" tine.
Billingsley Company plans to tie its wastewater main into the Leslie Tract
wastewater main at a manhole installed by the Leslie Tract as shown on attached
Exhibit B. The downstream wastewater main after the combined flow of 1250
GPM and 536 GPM will need to be a 15" wastewater main in lieu of the 12"
wastewater main that is currently proposed by you. This 15" wastewater main
will extend 1430' north along Belt Line Road, then bore across Belt Line Road to
an existing manhole at an existing 15" City of Camel' wastewater line (see
attached Exhibit B). Billingsley Company will agree to pay for one-half the
actual cost of this construction downstream of the shared manhole, which total
coat is estimated to be 550,182.50, based on your OPC dated September 2, 2011.
In the even Billingsley has to construct this downstream connection due to
schedule requirements, then Billingsley will utilize the Leslie Tract Engineer's
City approved plans for construction, and you will agree to reimburse, at time of
connection, one -half the cost of actual construction of this downstream
improvement. You will not be responsible for the sanitary sewer design within
Billingsley's property or obtaining permits to allow Billingsley's use thereof.
Regards,
BILLINGSLEY COMPANY Accepted Br
