property to the north. The Leslie Tract development shall:

2. Relau concentrated detained drainage flow, calculated to be 85 cis, at
the northeast corner of the Leslie Tract (see attached Exhibit A).

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 for one (1) bom crossing across Bch Line Road in lieu of two (2)
separate bore crossings. 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 1254
GPM from Billingsley and 536 GPM from the Leslie Tract projected to flow
through the proposed 15" line.
Billingsley Company plans to tic 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 treed 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 Lim Road, then bore across Belt Line Road to
an existing manhole at an existing 15" City of Coppell wastewater line (see
attached Exhibit B). Billingsley Company will agree to pay for one - half the
actual coat of this construction downstream of the shared manhole, which total
cost is estimated to be $50,152.50, based on your OPC dated September 2, 2011.
In the event 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 of obtaining permits to allow Billingsley's use thereof.
