Christie Nicklas moved to forward Case Z-532 to the Board of County Commissioners with a recommendation
of denial along with the Planning staffs recommendation for denial as it does not meet the PUD guidelines
and is too urban of a development for the area it is in. Bruce Fitzgerald seconded the motion.
The Chair asked the secretary to poll the members of the Planning Commission for their decision. John
Folsom, yes; Stephen Mokray, yes; Michael Miller, yes; Bryant Gimlin, yes; Bruce Fitzgerald, yes; Christie
Nickles, yes; Fred Walker, no. Motion carried.
After voting was completed Fred Walker further stated that the application is a compatible use of this land as
there are people who want to live on this land and for the Planning Commission to be presumptuous because
it feels there is something wrong with the application, not based on facts, is wrong. The property owner is in
limbo because of the two overlaying districts and his rights need to be addressed.
CHANGES TO SECTION 20 ORDINANCE 119-O
BUILDING OFFICIAL: Dennis Renley
REQUEST: Changes in requirements in the Weld County Building Code Ordinance concerning
engineered foundations.
Dennis Renley, Plans Examiner, Weld County Building Inspection Department, presented the changes to
Ordinance 119-O, the Weld County Building Code Ordinance. Dennis stated that these changes are for minor
changes to the electrical code wording to meet the correct guidelines and to change the requirements for
applications on additions to existing buildings.
Discussion covered whether this would cause a larger financial burden to the public or not. Dennis stated that
the change to the foundation guidelines will actually save most applicants between $300-$800. The current
requirements have all additions needing an engineered soils report with the application, while this change
allows more flexibility in open hole inspections with a Colorado Engineer's stamp and allowing matching
existing foundations.
Bryant Gimlin moved to approve the three changes to Ordinance 119-O. Christie Nicklas seconded the
motion.
The Chair asked the secretary to poll the members of the Planning Commission for their decision. John
Folsom, yes; Stephen Mokray, yes; Michael Miller, yes; Bryant Gimlin, yes; Bruce Fitzgerald, yes; Christie
Nicklas, yes; Fred Walker, yes. Motion carried unanimously.
SUBMITTAL DEADLINES AND FEE SCHEDULE FOR 2000
PLANNER: Monica Daniels-Mika
Monica Daniels-Mika, Director of the Department of Planning Services, presented the Planning Commission
submittal and hearing dates, including a revision to include the correct dates in November and the fee
schedule for the year 2000. Fred Walker asked if the fee schedule had increased any fees. Monica stated
that there were no changes in the fees , that the fees just have to be approved every year.
Stephen Mokray moved to approve the revised submittal and hearing dates and the fee schedule for 2000.
Michael Miller seconded the motion.

BUILDING TRADES ADVISORY BOARD
MINUTES
NOVEMBER 4, 1999 MEETING
Present:
Members:
Commissioner George Baxter
Scott Renfroe
Mark Doty
Jim Morris
James Fassler
Sam Ainsworth
Guest:
Dave Sprague
The meeting was called to order by Scott Renfroe at 7:00 AM
Doug Leafgren from Terracon was invited as a guest speaker. Mr. Leafgren has dealt with
foundation design and issues for over ten years.
One concern the board had was the cost involved in requiring engineered foundations. If a soil's
report is required by an engineering firm prior to foundation design, the cost could increase over
what is presently required. However, in some developments, a soil's report already exists.
Therefore, an open hole inspection may be all that is required by the engineer. This would result
is substantial savings compared to current Weld County requirements. Also, Terracon can do
both a percolation test and soils test at the same time. By making only one trip to the site, a
savings of$400-500 may be realized.
The board also indicated a desire to have an engineer do all the foundation inspections in lieu of
Weld County inspectors. It was felt that this would aid concrete contractors to have more
flexibility in scheduling inspections thus saving them time and money.
One of the provisions of our previous proposal was to allow a foundation for an addition to
match the existing foundation. Engineering would not be required if no structural damage was
detected by the inspector. Mr. Leafgren mentioned that foundation failures may not show up for
a number of years after the home is built. He recommended that we include in our language the
provision that a foundation be at least five years old and indicate no problems.
The Building Trade Advisory board unanimously approved a resolution stating these
recommendations.
The meeting was adjourned at 8:30 AM

RESOLUTION NOV 29 1999
November 4, 1999 RECEIVED
Homes and other structures are becoming more complicated with complex loading conditions. A
variety of soils types and conditions are encountered throughout the county. As a result, the
liability placed upon the building department is increasing. To reduce the risk to the homeowner
and the liability of Weld County we, as members of the Weld County Building Trades Advisory
Board, desire to recommend that all foundations in Weld County be designed and inspected by a
Colorado Licensed Engineer or Architect.
We also recommend the following exceptions to this general rule:

footage of the existing home.
2. The height of the addition does not exceed the height of the
existing home.
3. The existing foundation shows no signs of settling or structural
damage.
4. The addition foundation shall be the same type and dimensions as
the existing foundation.

MEMORANDUM
-
yne To:From Clerk Dave Sprague, Building Official � November 23, 1999'.
COLORADO
Subject: Amendments to Ordinance 119-O
The purpose of this memo is to request that the proposed amendments to Ordinance 119-O be
scheduled at the next public hearing by the Board of County Commissioners.
I'm including three documents. The first are the minutes from the Planning Commission meeting
held November 2, 1999. (The approval and comments by the Planning Commission can be
found on page five.) The second group of papers contain the revision that we presented to the
Planning Commission. We are asking that the entire Section of 20.1.13 be revised.
Since the Planning Commission hearing, we have met with the Weld County Building Trades
Advisory Board. They made two recommendations. One was that engineer or architects be
allowed to perform foundation inspections in lieu of building inspectors. The second was that
foundation of existing homes must be five years old and show no signs of deterioration.
Both of these new changes are underlined and bolded. If these changes are approved, the
underlining and bolding will be removed from the final document.
If you need any further information, please call me.
