SUBJECT: Recommendations for Changes in Refuse Collectlon Ordinance
Introduction
This report recommends that the Refuse Collection Ordinance be modified
to provide that owners of multiple residential unit buildings with SlX
units or more be required to have bin container service. It also
recommends changes which will require that a discharge shutoff system
be installed in all bUlldings with refuse chutes.
Background
At the present time, the City offers refuse service to multiple residential
units, and it is the option of the property owner whether or not they wish
to provide thelr own containers (garbage cans) or if they wish to rent
larger bin containers from the City. For duplexes and residential units
up to approximately $lX units, cans are a satisfactory method of containing
the refuse while it awaits collection. For larger residential complexes,
the number of cans becomes so large that it is inefficient for the City
and unsightly to residents for the property owner to use cans as opposed
to bins. Therefore, it is proposed to establish a limlt on the number of
units where property owners may use cans for refuse and to reaUlre that
the owners subscrlbe for bin service if the number of units is In excess
of this limit. This proposed change will affect approximately 500
residential units (about 70-80 customers). The increased cost to the

owner of a typical 6 - 10 unit building will be the bln rental charge
($4.00 per month for a two-cubic-yard bin).
Many multiple residential and office buildlngs have been and are being
designed with refuse collection chutes. Some of these systems have a
shutoff gate at the bottom which can be closed by the refuse workers when
they come to empty the bin. On the buildings WhlCh do not have these
shutoff gates. the refuse frequently backs up in the chute and falls on
the floor when the bin is removed for emptying. creating a great deal
of extra unnecessary work to clean up the refuse.
There are several manufacturers of these gates and the installed costs for
them dre from $250 to $700 as shown on the attached sheet.
This problem only exists for the Clty when there is on-site refuse
collection. Therefore. it is recommended that such systems be made a
condition of on-site collection by the City.- If the owners of the buildlng
wish to take the responsibility for pushing the bin out to the alley, there
would be no changes required.
Recommendation
It is recommended that the City Attorney be instructed to prepare modifications
in the Refuse Ordinance to require that bins be required for residentlal com-
plexes with six units or more and to require dlscharge shutoff systems for
all new buildings with refuse chutes and for all existing buildings with
chutes within the next six months, as a condition of on-site refuse service.
