INTEROFFICE MEMORANDUM
TO: VILLAGE MANAGER MICHAEL E. JANONIS
FROM: PROJECT ENGINEER
DATE: JULY 31, 2014
SUBJECT: 2014 BACKYARD DRAINAGE PROGRAM
(CONTRACT AWARD NOT TO EXCEED $100,000.00)
Background
Many properties in Mount Prospect experience recurring backyard flooding after any significant rain event. Often
water will pond in their yards and remain there for a considerable length of time. On May 13, 2008, the Village Board
authorized Staff to proceed with the Backyard Drainage Program in an effort to assist residents in reducing the
backyard flooding they experience.
Staff has received requests for assistance through the Backyard Drainage Program for over 200 residential
properties. Staff identified several of the properties experiencing the worst flooding, based upon such criteria as
depth of ponding, area of inundation, number of properties affected, structures impacted, and duration of ponding.
Staff then surveyed the existing conditions, and prepared plans to better drain each of these properties. Each design
includes an inlet in the backyard draining through a pipe connecting to the existing sewer system in the public right of
way. To protect the receiving system from being overwhelmed, each design includes a restrictor that will control and
slow the discharge into the receiving sewers. These restrictors, while serving to protect the Village sewer systems,
may cause water to pond in the backyards during heavy rain events for a short duration. To accommodate this
ponding water, rain gardens will be installed around the inlets. These rain gardens will provide a place for any
ponding water to accumulate, and provide a mechanism for the water to infiltrate into the ground quickly.
Following construction, the property owners will be responsible for maintenance of the storm sewer and rain gardens
on the private properties; however, it shall be the Village's responsibility to maintain the new storm sewer in the
public right of way. Each design is contained on a single property, avoiding the need for easements or agreements
between property owners.
Bid Results
Sealed bids for the 2014 BACKYARD DRAINAGE PROGRAM were publicly opened and read aloud on July 28, 2014
at 1:00 P.M. A Notice to Bidders was published in a local newspaper as required and invitations were sent to
contractors familiar with this program. A mandatory pre -bid meeting was held on July 21, 2014 at 10:00 A.M. to
discuss the intent and specifics of the program, as well as to answer any questions the contractors may have had in
formulating their bids. Six (6) contractors attended the pre -bid meeting.
Three (3) of those contractors submitted bids for this project. The bids ranged from a low of $90,620.00 by Martam
Construction, Inc., to a high of $204,680.00 by Kovilic Construction Company, Inc. The Engineer's estimate for the
project was $99,634.00.
Each of the bidders submitted a bid bond in the amount of 5% of the total bid as required in the bid proposal packet.
All bids were checked for their accuracy. No errors were found. All bidders correctly signed their bids and bid bonds.

Discussion
The low bidder, Martam Construction, Inc., successfully completed work on many Village projects, including the 2009
Backyard Drainage Program.
This is the fourth year of the Backyard Drainage Program. The history of the program is summarized below:
2009 — Completed installation at eleven (11) sites.
2011 — Completed installation at seven (7) sites.
2013 — Completed installation at four (4) sites.
Funds were not available in either 2010 or 2012, so no construction was performed under the Backyard Drainage
Program in those years.
We estimate that installation can be completed on four (4) sites this year. However, because the cost is based on
estimated quantities, the project will be evaluated throughout the course of construction to determine if any sites can
be added, or have to be deferred until additional funds become available. Because of the estimated quantities, and
to have the capability to extend the program to additional sites if the opportunity presents, I recommend that the
contract be awarded to the available budget amount of $100,000.00.
Recommendation
I recommend the contract for the 2014 BACKYARD DRAINAGE PROGRAM be awarded in an amount not to exceed
$100,000.00 to the low bidder, Martam Construction, Inc. There are sufficient funds in the 2014 Budget to cover this
proposed contract.
Please include this item on the August 5 Village Board Meeting Agenda.
I concur with the above reco mendation.
