Agenda Number:
Title: Consider executing Supplemental Contract No. 1 with Kimley-Horn and
Associates, Inc. for the Lake Creek 10 & Lake Creek 11 Wastewater
Improvements Project.
Type: City Manager Item

Agenda Date: 2/1/2019

Text of Legislative File CM -2019-0036
In the City's Wastewater Master Plan, it identified two line sections of the Lake Creek 10 and
Lake Creek 11 wastewater interceptors which need to be upsized to meet the needs for this
interceptor at buildout. The construction of a few higher density developments have resulted in
the need to upsize these line sections of the interceptor at this time. The Lake Creek 10
wastewater line improvements will upsize approximately 1,400 linear feet of existing 10 -inch
wastewater line to 12 -inches in diameter and Lake Creek 11 wastewater line upsize
approximately 2,700 linear feet of existing 8 -inch wastewater line to 10 -inches in diameter.
Supplemental No. 1 is needed to re-route approximately 700 linear feet of the proposed 1,400
linear feet of 12 -inch wastewater line identified as Lake Creek 10. It has been determined that
enlargement of a portion of the existing wastewater line could potentially cause damage to
existing nearby structures. The associated cost includes surveying, geotechnical, design, and
TCEQ permitting.
Cost. $21,300
