Included in the Airport's Capital Improvement Program is the Pond C Outfall Improvements Project. As a result of the extreme rainfall events of 2010 and 2011, the Airport has undertaken measures to improve the Airport's storm water detention ponds.  This is the third project the Airport  has undertaken to improve storm detention ponds A, B, and C .  The first two projects increased the capacity of the ponds to hold a 100-year 24-hour rain event and upgraded the dikes around the ponds to withstand the potential impacts of higher pond levels.   The heavy rainfall associated with the Fathers Day storm in 2010 and the record setting May 24, 2011, storm both produced more rain water than the detention ponds were designed to hold, and for the first time since the ponds were constructed in 1976, excess water flowed out of Pond C and into the natural drainage and down into the Moon Valley subdivision.  Working with the current property owner in Moon Valley, where the majority of the water flowed, a Construction and a Maintenance Easement has been negotiated for the construction phase of the project and for its future maintenance, and a copy is available for review at the City Clerk's office.  This project will construct a swale from the outfall of Pond C to the edge of the rims, a plunge pool/energy dissipater at the bottom of the rims to collect the water and reduce its velocity, and a spillway from the plunge pool to the street with three additional energy dissipating baffles to further reduce the water's velocity.  Again, this is an emergency relief system that will hopefully never need to be used, but will be in place should the Airport ever incur another 100+ year storm.  This project was advertised in the Billings Times for three weeks, and was on the City's Website.  At the September 10, 2012 Council meeting, the bid award was delayed until September 24, 2012, to allow time to finalize easement negotiations with the property owner.

On August 28, 2012, the following bids were received for this project:

Contractor	Bid
The Good Earth Works Company, Inc.	$70,100
Donnes, Inc.	$85,050

The City Council may:

• Approve the Easements for the project's construction and maintenance, accept the low bid, and award the contract for the Pond C Outfall Improvements Project; or
• Not approve the Easements, reject all bids, and subsequently delay the project.

The total cost of this project is $70,100.  Funds are available in the Airport's Passenger Facility Charge (PFC) capital  account.

Staff recommends that the City Council approve the Construction and Maintenance Easements and award the Pond C Outfall Improvements Project to the low bidder, The Good Earth Works Company, Inc., for the amount of $70,100.
