NOW THEREFORE, it is mutually agreed to amend the original Professional Service Agreement as
follows:
I. Project Description
The Dry Run Creek Interceptor Project includes construction of pumping station, force main
and sanitary sewer along the San Marnan corridor. The project will provide capacity for
continuing to expand the area south of San Marnan Drive and also re -direct flow from the
current Tower Park Pumping Station out of Service Area No. 19 to reduce some
overloading in the 9th Street corridor. The new pumping station will replace the Tower Park
Station. The new force main will take flow from the pumping station to the east along San
Marnan Drive (about 2,700 LF) to a gravity sewer system along San Marnan Drive (about
8,500 LF), which will flow east and connect to the existing sanitary sewer along Hess Road.
The project provides numerous benefits for economic development and improves flow
conditions in a portion of the system which currently experiences overloading during wet -
weather flows.
This project was first designed and permitted in 2015. After 2015, the City pursued utilizing
State Revolving Fund (SRF) as the funding source for the project. The project has had
several redesigns since that time that include doubling the capacity of system to allow for
more growth in the area served, adding emergency power to Hawkeye Lift Station,
revisions required to comply with the updated code requirements in later years and SRF
requirements. During the easement acquisition phase, there were a number of items
required by one of the landowners that led to some additional design revisions for the
project. In addition, during the bidding period, additional soil borings were acquired to
further determine the amount of rock removal needed to build the project.
