Discussion and consideration of approving a Water Line Development
Agreement, a Sanitary Sewer Impact Fee Credit Agreement between the City of
Coppell and Vista Partners and authorizing the Mayor to sign.
Date: March 18, 1996
On May 9, 1995, Council approved an agenda item authorizing staff to negotiate a drainage
contract with Vista Partners that allowed for a $10,000 up front payment and an additional credit
to the Roadway Impact Fee of $115,000. The agreement entitled "Agreement for the
Acquisition of Alternative Drainage Improvements" is the agreement prepared that would Satisfy
those two items that Council has previously agreed upon. As a reminder, the basis of the
agreement was the ability of the City to reroute water to a drainage system that Vista had built
through their property located north of Denton Creek at a time when the property was
considered to be within the City of Lewisville. By allowing the City to discharge into that
system, there ends up being a savings in excess of the amount offered as credit to Vista to the
overall project that includes the construction of Denton Tap Road from Parkway Blvd. north to
the north city limits.
The second agreement entitled "Agreement for Sanitary Sewer Impact Fee Credit" is an
agreement whereby Vista is requesting reimbursement for the oversizing of various lines within
their property as authorized by the Subdivision Ordinance. The Subdivision Ordinance allows
an oversizing reimbursement for anything over 12" in diameter. Vista is requesting that oversize
reimbursement for the 18" sanitary sewer being constructed that would service not only their
property but also the property referred to as Magnolia Park and the area west of Magnolia Park
all the way to S.H. 121. The approximate amount of the oversizing reimbursement requested
by Vista is $75,150. In lieu of a check being processed to Vista, Vista is agreeable to take that
credit as an offset to their sewer impact fees at such time as the property develops.
The third agreement entitled "Water Line Development Agreement" is a request by Vista to be
reimbursed for the construction of a 12" water line adjacent to and on the south side of S.H. 121
running from Denton Tap eastward all the way to MacArthur Blvd. The approximate cost of
the reimbursement is $304,200. The reason behind this request is that the 12" water line was
used in the calculations of our Impact Fee Schedule for Water Systems. Our Impact Fee
Ordinance states that they can get credit for the construction of that line as long as the credit
does not exceed the dollar amount used in the study for the anticipated cost. The dollar amount
used in the study was $60/per foot, which is referred to in paragraph one. The 79.3 % comes
from the fact that the line from MacArthur to Denton Tap is 79.3 % of the total length of the line
as outlined in the Impact Fee Capital Improvement Plan. Once this line is in the City water
system, we will be connecting the 12" water line currently under construction along North
Denton Tap Road to it. We will then begin seeking ways to construct the missing link south
from S.H. 121 along MacArthur Blvd. to the Peninsulas of Coppell. Once this line is in the
water system, it will provide dual feeds to the north side of Coppell and should increase volumes
and pressures along the northern edge of Coppell.
All three agreements have had extensive legal review by an attorney for Vista Partners and by
Peter Smith. It is my opinion that by signing the drainage agreement the City is gaining an
alternative way to discharge water, thereby, potentially saving a substantial amount of dollars
in the construction of North Denton Tap Road; 2) by approving the water agreement the City
is gaining a valuable link in the water system for the north side of Coppell; and 3) by approving
the sewer agreement the City is basically complying with its Subdivision Ordinance.
Staff recommends approval of all three agreements and recommends that the Mayor sign all
three agreements. Staff will be available to answer any questions at the Council meeting.
