(CIP 7202044)
INTRODUCTION
The enclosed resolution provides for the acceptance of the construction contract for the
Green Alley Pilot Project (11th - 13th between White & Jackson Streets).
BACKGROUND
The Green Alley Pilot Project involved the reconstruction of two existing asphalt alleys
from 11th Street to 13th Street between White Street and Jackson Street.
Two different pervious pavement surfaces--porous asphalt and interlocking concrete
pavers--were used to evaluate suitable pavement types for future assessable alley
reconstruction projects. The pavement in the alley between 11th & 12th is high-strength,
interlocking concrete pavers. The alley from 12th to 13th streets is porous asphalt. Both
pavement surfaces will allow rainfall from low-intensity storms to pass through the
pavement structure. This, in turn, will recharge the water table and minimize stormwater
runoff.
Both alleys have a concrete border around the pervious surface. This concrete border
serves as transition pavement from the adjoining driveways to the pervious surface in
the alley. At the ends of each alley is a concrete imprint that identifies the alley as a
green alley. This will help identify that these alleys are different from conventional
alleys. The project also included: reconstruction of sanitary sewer manholes; watermain
reconstruction; replacement of private lead services; and the reconnection of copper
water services to the watermain.
Since this was a pilot project utilizing Community Development Block Grant funding, the
project was non-assessable.
DISCUSSION
The Green Alley Pilot Project (11th - 13th between White & Jackson Streets) was
completed by Portzen Construction, Inc. of Dubuque, Iowa, in the final contract amount
of $199,966.88, which is a 7.1 % decrease from the original contract in the amount of
$215,274.25.
RECOMMENDATION
I recommend that the City Council accept the improvements and authorize payment of
the contract amount of $199,966.88 to Portzen Construction, Inc. of Dubuque, Iowa, for
the Green Alley Pilot Project (11th - 13th between White & Jackson Streets).
