All Ayes – Motion Carried Public Hearing – 400 Wilson Variance Request Moved by Commissioner L. Van Lankvelt, seconded by Verboomen to enter Public Hearing at 6:01 PM All Ayes – Motion Carried Director Kittel presented a request to add on to an existing detached garage at 400 Wilson Street. This was posted in newspaper, residents within 100 feet were notified, no questions or concerns were posed to staff from residents. This would exceed size and height permitted in Village ordinance. Staff have reviewed and find no concern with the request. Commissioner Van Lankvelt asked if neighbors were contacted. The applicant, Mr. Marx said it was discussed and questioned had been answered. Mr. Marx stated the larger garage would allow him continue working on his passion, cars. Director Taylor asked about discussion on the curb with the garage. Director Kittel stated no proposed changes to the curb cut. Storm water would run directly to the street. Moved by Commissioner Verboomen, seconded by Commissioner Van Lankvelt to exit Public Hearing at 6:09 p.m. All Ayes – Motion Carried Discussion/Action – 400 Wilson Variance Request Commissioner Moes stated he does not support an addition to the garage over 400 square feet. The request is too large for the lot size, he does support the height increase. The maximum size allowed to stay under 35% would be a 523.75 square foot addition. President Vanden Berg stated he would support a 35% addition. Moved by Commissioner Verboomen, Seconded by Commissioner L. Van Lankvelt to approve the request up to 35% of lot coverage without regard to the height difference. All Ayes – Motion Carried Discussion – Section 8 Update Director Kittel presented the second portion of section 8 for review. Changes are included in the packet for review. Many of the changes simplify the ordinance. Items for Future Agenda Director Kittel stated there is a request for a review of setbacks on fences for commercial properties. More information will be presented in future meetings. Adjournment Moved by Commissioner L.

Over the years there have been some minor updates but, upon recent review there are some needed updates. Due to the size of the Ordinance Staff is breaking up the revisions into smaller segments to present for review. Attached is the third round of updates for Article IV of Section 8, the text highlighted and strike through are deletions Red and Underline are additions to the ordinance. With how the updates are currently proposed in Sec 8-21 the code has been adopted for all trades meaning Article IV is mostly no longer needed and redundant in its current format. The portion discussing HVAC permits and fees will be covered now in Sec 8-20 and 8-32. Section 8 will need to be re-organized and re-number before a final presentation of the updates are presented. The main changes to this portion of Section 8 are: -Removing language referring to the Heatin, Ventilating and Air Conditioning code of the Village of Little Chute -Updating code reference to the new updated building Code - simplifying language and removing unnecessary items, the definitions previously provided are part of the referenced building code. The HVAC code is adopted in updated language -Sec 8-87 through 8-91 and 8-93 through 8-95 are deleted as no longer needed. -Sec 8-92 is to remain for now but, may be combined with Sec 8-20 pending final review Fiscal Impact: None Recommendation/Board Action: Discussion on updates to Sec 8 Respectfully Submitted, Dave Kittel, Community Development Director  - CODE OF ORDINANCES Chapter 8 - BUILDINGS AND BUILDING REGULATIONS ARTICLE IV.

Minimum requirements for the installation of gas-fired heating equipment and piping. In addition to the standard referred to in section 8-89, which shall be classed as minimum standards of this article, the installation of gas heating equipment shall conform to the requirements set forth in this section: (1) Scope. a. Applicability. The provisions of this article, unless otherwise indicated herein, shall apply only to utilization pressure (not in excess of one-half pound per square inch) gas pumping systems extending from the gas meter outlet connection to the inlet connections of appliances. They are intended to cover the design fabrication, installation and test of gas piping systems for fuel gases such as natural gas, liquefied petroleum gas, liquefied petroleum air, gas or mixtures thereof. They are not intended to cover systems or portions of systems supplying equipment engineering, designed and installed for specific manufacturing, production processing, large power generating application, melting and treating furnaces, production ovens and similar applications. b. Exception. Gas piping and control equipment requirements for systems using gas pressures in excess of one-half pound per square inch: 1. Generally, the valving arrangement shall conform to the American Standards Association (ASA Z21.33—1950). The community development director will recognize as approved valving, arrangements and designs approved by any other nationally recognized approved agency. 2. A safety relief valve shall be placed downstream from a gas pressure regulator where gas is supplied at pressures in excess of one-half pound per square inch. The discharge from the relief valve shall be piped to a safe location outside the building. (Valve setting not to exceed four pounds.) Created: 2023-08-07 10:11:00 [EST] (Supp. No. 15, Update 1) Page 4 of 18  3. Provide a suitable pressure gauge in the gas line located downstream from the pressure regulator. 4. Where a gas supply pressure is higher than that at which the burners are designed to operate, a gas pressure regulator shall be provided to reduce pressure to satisfy design conditions. 5. Where the gas supply pressure is in excess of one-half pound per square inch, the piping system shall be identified indicating the maximum line pressure. It is recommended that the legend "Gas ___ psi." (pressure per square inch to be inserted in the blank) be applied on gas piping near and downstream from pressure regulator at intervals of 50 feet in every room or area which is less than 50 feet. 6. Submit two copies of drawings (schematic is acceptable) and specifications to the community development director for review and approval. (2) Work on gas piping containing unmeasured gas. Disconnecting inlet of gas meter, changing meter location or making connection to gas service pipe shall be done only by gas company employees or others authorized by the gas company to do such work. A pipe fitter shall connect or disconnect the building piping from outlet meter connections when necessary. No person, unless in the employ of the gas company or having permission from the gas company, shall turn on or reconnect gas service in or on any premises where and when gas service is not at the time being rendered. It shall further be unlawful to turn on or supply gas on or at any premises unless at least one gas appliance is connected to the gas piping system and all outlets are properly and securely connected to appliances or capped or plugged with screw joint fittings. (3) Authority to disconnect. The community development director or the gas utility is hereby authorized to disconnect or have disconnected any gas space heating equipment or gas piping which shall be found not to conform to the requirements of this article or which may be found defective and in such condition as to endanger life or property. Where such disconnection has been made, a notice shall be attached to such equipment or gas piping be reconnected until authorized by the community development director to do so. Cost of such disconnect by the community development director shall be paid for by the owner of the premises. (4) General precautions. a. Installation of gas piping. Installation of gas piping shall be performed with the gas turned to off to eliminate hazards from leakage of gas. Connection of the new piping system to the existing system shall be done, if practical, with the gas turned off. b. Burner and pilot valves. Before turning off the gas at the meter, except in cases of emergency, all burner and pilot valves on the premises supplied with gas through the meter shall be turned off and the meter test hand observed for a sufficient length of time to ascertain that there is not gas passing through the meter. When there is more than one meter on the premises, precaution shall be exercised to ensure that the proper meter is turned off. c. Checking for gas leakage. No matches, candles, flame or other source of ignition shall be employed to check for gas leakage from meters, piping or appliances. Check for gas leakage with a soap and water solution. d. Artificial illumination. Artificial illumination used in connection with a search for gas leakage shall be restricted to electric hand flashlights, fixed electric lights controlled only by explosion-proof safety switches or switches remote from the area of the leakage or approved safety lamps. e. Smoking not permitted. When connecting or disconnecting pipe which contains gas, smoking shall not be permitted. Created: 2023-08-07 10:11:00 [EST] (Supp. No. 15, Update 1) Page 5 of 18  f. Electric circuits grounded to gas piping. Except for appliance controls requiring a ground electrical system, including low voltage, circuits shall not be grounded to gas piping. (5) Piping to meter location. a. Piping extended to meter location. Gas building piping shall be extended to the meter location specified by the gas company. The meter location and gas piping connection shall be such that the meter connections are easily accessible in order that the meter be read or changed. b. Piping marked. Piping from multiple meter installations (four or more meters) shall be plainly marked near outlet connection with a permanent tag by the installer so that the piping systems supplied through them can be readily identified. c. Meters supplied by single service pipe. Unless otherwise approved in writing by the gas company, all meters supplied by a single service pipe shall be at the same location. d. Piping systems not interconnected. Unless otherwise approved, where two or more meters are installed on the same premises but supply separate consumers, the piping systems shall not be interconnected on the outlet side of the meters. e. Pipe capacity. Gas building pipe capacities shall be as established by state law and state administrative code standards. (6) Size of piping to gas appliances. a. Sufficient size. Piping shall be of such size and so installed as to provide a supply of gas sufficient to meet the maximum demand without undue loss of pressure between the meter and the appliance. The minimum gas pipe shall be not less than three-fourths-inch. This does not apply to water heaters, space heaters and unit heaters with inputs of less than 50,000 input. The size of the gas pipe to be used depends upon the following factors: 1. Allowable loss in pressure to be provided for. 2. Maximum gas consumption to be provided for. 3. Length of pipe and number of fittings. 4. Specific gravity of the gas. 5. Diversity factor. b. Pressure loss. The pressure loss in any gas piping system from the gas meter to any appliance for the maximum demand shall not exceed 0.3-inch water column. The minimum size of piping required to comply with the 0.3-inch pressure loss limitation shall be determined by the procedure given in subsection (6)c of this section or by standard engineering methods, including use of gas flow computers. c. Size of piping. To determine the size of any section of gas pipe in a system, proceed as follows: 1. Measure the length of pipe from the gas meter to the most remote outlet of the building on that piping system. When separate or individual fuel lines are extended from the meter to one or more appliances, such as an individual gas line to heating plant, each separate fuel line from the meter shall be considered as a separate system. 2. In Table No. 1, select the horizontal line showing the distance or the next longer distance if the table does not give the exact length. 3. Use this horizontal line so selected to locate all gas demand figures for this particular system of gas piping. Created: 2023-08-07 10:11:00 [EST] (Supp. No. 15, Update 1) Page 6 of 18  4. Starting at the most remote outlet, find in the horizontal line just selected the gas demand for that outlet. If the exact figure of demand is not shown, choose the next larger figure in the same horizontal line. 5. Above this demand figure in the first line at the top of Table No. 1 will be found the correct size of pipe required to serve such an outlet. 6. Proceed in a similar manner for each outlet and each section of pipe. For each section of pipe, determine the total gas demand supplied by that section and use the length indicated by subsection (e)(5) of this section, which length is at all times taken as the total distance from the meter to the most remote outlet. 7. The hourly volume of gas required at each outlet shall be taken as not less than the maximum hourly rating specified by the manufacturer of the appliance to be connected to each such outlet. Where the manufacturer's rating of an appliance is given in British Thermal Units (BTU) per hour, this rating shall be divided by 970 to obtain the corresponding gas demand in cubic feet per hour for natural gas. Where BTU rating of gas appliances to be installed has not been definitely specified, estimate of approximate requirements may be based on current typical appliances. d. Extensions to existing piping. Extensions to existing piping shall conform to subsection (6)a of this section. Existing piping, if extended, shall be converted to the proper size of pipe where necessary. In no case shall extensions be made to existing pipe which is smaller than permitted by subsection (6)a of this section. (7) Materials for pipe and fittings. a. Rigid pipe and fittings. 1. Gas pipe shall be black wrought iron or steel pipe complying with the American Standard for Wrought Iron and Wrought Steep Pipe ASA B36 D—1939. All pipe fittings (except shutoff cocks or valves) shall be malleable iron or steel when with wrought iron or steel pipe. In sizes three inches or larger, all piping must be welded. (See subsection (7)a.2 of this section.) Exception: plastic pipe may be used outside of a building only and when it is buried at a minimum depth of 12 inches and when it is used in the sizes of three-eighths- inch outside diameter for gaslights and five-eighths-inch outside diameter for gas grills. The plastic pipe must be an approved type. 2. The use of welded steel fittings, either shop or field fabricated, and jointing of pipe by welding is permissible. 3. Plain end pipe with gland-type couplings shall not be used within or under any building or structure but may be used for exterior or underground installations. 4. Ground joint unions or gasket-type unions with leather gaskets shall be used in gas building piping. 5. Copper or brass pipe in iron pipe sizes when assembled with threaded fittings of the same material may be used. Copper tubing with seat, flared or compression fittings shall not be used for building piping. 6. Aluminum piping in iron pipe sizes may be used provided that no aluminum pipe may be used for underground installations, nor in contact with masonry or concealed in walls or partitions constructed of masonry materials, nor exposed to alkaline chemicals, fumes or materials. Aluminum pipe shall not be extended through walls or ceilings. Created: 2023-08-07 10:11:00 [EST] (Supp. No. 15, Update 1) Page 7 of 18  b. Semi-rigid tubings and flexible metal connectors.
