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. 2000-0802 ('.l 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 v .J county Planning Dept. 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: 20.1.13.1 Add Section 1806.1.1 Exception 1: The requirements of Section 20.1.13 of this Code shall not be required for an addition foundation to a Group R, Division 3 Occupancy when all of the following conditions are met: 1.

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. 5. The existing foundation is five or more years old and does not consist of caissons and grade beams or any other design that would indicate that the original foundation was designed for expansive soil conditions. 6.

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. Hello
