PUBLIC WORKS DEPARTMENT (214) 450-2811 Post Offil:e Box 144 Addison, Tcxns 75001 16801 Westgrove September 6, 1994 MEMORANDUM To: Ron Whitehead City Manager From: John Baumgartner Director
of Public Works Re: Sewer Tunnel and Related Projects In the early 1960's the Town of Addison entered into a fifty year agreement exchanging sewer service for the west side of town;
for land that is currently occupied by a portion of the Brookhaven College Campus. This agreement remained in place until 1986 when the Town's growth started to surpass Farmers Branch's
ability to provide sewer service without major infrastructure improvement. Fanners Branch and Addison litigated the dispute to determine Farmers Branch's responsibility to provide Addison
with sewer service. Addison prevailed in the lower court; but On appeal it was detennined that the original agreement was vague and Fanners Branch was not obligated to provide Addison
with uniimited sewer service. Consequently, Addison and Farmers Branch entered into a series of interim 6 month agreements affectively limiting our sewer flows through their community
to 105 %of the 1986 flow. These agreements work effectively during the slow growth years of the late 80's and early 90's. During tbe initial years of the interim agreements, Addison
and Fanners Branch studied the various methodologies to eliminate the constraints to their sewer systems and provide opportunities for new growth. After looking at the various options,
it was deterroined that a cooperative effort with Farmers Branch to construct a series of sewer interceptors from the North Dallas Tollway to the Trinity River Authority (TRA) interceptor
at the Trinity River and 635 was tbe most cost effective method to meet Addison's needs for sewer. Since 1991, Addison has experienced a growth spurt in the western portion of the community
including K-Mart, Sams, Winn Dixie, several restaurants and the construction of over 500 new homes, additional apartments and retail shops. In an effort to satisfy the demand for sewer,
Addison has borrowed capacity from Dallas on a five year basis. Consequently, we have begun to implement the plan that should provide for Addison's sewer needs well into the 21st century.
The following four pbases represents Addison's commitment to implement the plan necessary to provide sewer service: 
Phase I -Addison/Farmers Branch Sewer Tunnel. 20,500 linear feet of 60 inch sanitary sewer line from the Trioity River at 1635 to Marsh Lane at Farmers Branch Creek. Design -Started
in late 1991 with the bid opening in July 1993. Contract Awarded -September 1993 to Seven K Construction Company, Inc. Construction Started -December 1993 Anticipated Completion -October
1995 Costs -Approximately $13.5 million 57 % Addison $ 7.7 million 43 %Farmers Branch $5.8 million Notes: The contractor continues to have minor difficulties regarding site conditions
and equipment. He is hopeful that they can make up some of the time lost with better production between 135 and Marsh Lane. Schedule has slipped incrementally from August to October.
The project is approximately 25 % complete. Phase H -AddisoniFarmers Branch Sanitary Sewer Interceptor -(Phase II) This phase coosists of a series of smaller diameter (15 inch to 30
inch) lines from Marsh Lane at Farmers Branch Creek to the North Dallas Tollway near Spriog Valley. This This project is almost entirely located within Farmers Branch and provides service
to Addison's south Midway Road/Spring Valley areas and to the south Quorum area. Design -Started in January 1994 Bid opening -Estimated January 1995 Start construction -Estimated March
1995 Completion -Estimated March 1996 Costs -Approximately $2.4 million 38% Addison $0.9 million 62%Farmers Branch $1.5 million Phase ill -Marsh Lane Interceptor -This phase of the project
consists of approximately 8000 l.f. of 24 inch sewer line. When completed it will connect the Addison-Farmers Branch sewer tunnel to Addison's sewer system at Marsh and Belt Line. Design
-Started in January 1994 Bid award -Scheduled for September 13, 1994 Start construction -Estitnated November I, 1994 Completion -Estimated November 1995 for substantial completion with
fmal cleanup by January 1996 Costs-Approximately $3.9 million 100% Addison Notes: This project will be a tunnel project in an effort to minimize disruption to the public and to eliminate
the continual expense of operating a major sewer lift station. 
Phase IV -Midway/BeIt Line Road Sewer Interceptor -This phase ofthe project is approximately 7,500 linear feet and will include a lift station, force main and conventional sewer system.
It provides a method to move Addison's sewer in the northwest part of town from the Carrollton system to the Marsh Lane Interceptor. This is consistent with our commitment to Carrollton
to be off their system when the runnel is complete. Design -The feasibility srudy was completed in August 1994 and the consultant is reviewing site selection for the lift station and
routing of the forcemain and conventional line. Schedule -Depending on the requirements for land acquisition, it is intended to award a construction contract in the spring of 1995 and
complete the project by the spring of 1996. Cost -Estimated at $2.9 million -100% Addison. Summary 1964 -Entered 50 year agreement for Farmers Branch to provide sewer service in exchange
for a favorable Boundary Adjustment. 1986 -Court determines original 1964 agreement is not valid valid and Farmers Branch is not obligated to provide unlimited sewer capacity. 1987 -Town
enters into the first of a series of Ii month agreements with Farmers Branch for constrained sewer service. 1987-90 Various sewer alternatives are studied and it is determined that a
series of sewer interceptors from the North Dallas Tollway to the Trinity River under Farmers Branch is the most cost effective solution. 1991 -The North Dallas County Water Supply Corporation
is created. 1992 -Design begins on the first phase of the sewer interceptor. 1993 -The contractor was issued a notice to proceed on the first phase (sewer tunnel) of the project. 1994
-Design is started on phases II, Ill, IV. 1995 -Estimated completion of phases I and III in the late 1995. 1996 -Estimated completion of phases II and rv in early 1996.

Addison had a sewer line 9Qlnq under Marsh Just south of Beltline Road. It was declded to up size the line to hold future capacity. rhe line would have been about a 30" line. The Branch
