PART 3 EXECUTION

3.01 SURFACE PREPARATION
A. Allow new pavement surfaces to cure for a period of not less than 14 days before application of marking materials.

B. Thoroughly clean all surfaces to be marked before application of paint. Remove dust, dirt, and other granular surface deposits by sweeping, blowing with compressed air, rinsing with water, or a combination of these methods. Completely remove rubber deposits, existing paint markings, and other coatings adhering to the pavement with scrapers, wire brushings, sandblasting, mechanical abrasion, or approved chemicals as directed by the Owner’s Representative. The application of paint conforming to Fed. Spec. TT-P-1952D is an option to removal of existing paint markings on asphalt pavement. Apply the black paint in as many coats as necessary to completely obliterate the existing markings.

Where oil or grease are present on old pavements to be marked, scrub affected areas with several applications of trisodium phosphate solution or other approved detergent or degreaser, and rinse thoroughly after each application. After cleaning, seal oil-soaked areas with cut shellac to prevent bleeding through the new paint. Pavement marking shall follow as closely as practicable after the surface has been cleaned and dried, but do not begin any marking until the Owner’s Representative has inspected the surface and gives permission to proceed. The Contractor shall establish control points for marking and provide templates to control paint application by type and color at necessary intervals.

The Contractor is responsible to preserve and apply marking in conformance with the established control points.

3.02 APPLICATION

Apply uniformly painted and reflective pavement marking of required color(s), length, and width with true, sharp edges and ends on properly cured, prepared, and dried surfaces in conformance with the details as shown and established control points. The length and width of lines shall conform within a tolerance of plus or minus 3 inches and plus or minus

SECTION 32 17 23 PAVEMENT MARKINGS
PAVEMENT MARKINGS 32 17 23 - 3 of 3
1/8 inch, respectively, in the case of skip markings. The length of intervals shall not exceed the line length tolerance. Temperature of the surface to be painted and the atmosphere shall be above 50 degrees F and less than 95 degrees F. Apply the paint at a wet film thickness of 0.015 inch. Disperse reflective glass beads evenly on the wet paint at a rate of 6 pounds per gallon of paint. Apply paint in one coat. At the direction of the Owner’s Representative, markings showing light spots may receive additional coats. The maximum drying time requirements of the paint specifications will be strictly enforced, to prevent undue softening of asphalt, and pick-up, displacement, or discoloration by tires of traffic. If there is a deficiency in drying of the marking, discontinue paint operations until cause of the slow drying is determined and corrected. Remove and replace marking that is applied at less than minimum material rates; deviates from true alignment; exceeds stipulated length and width tolerances; or shows light spots, faulty distribution of beads, smears, or other deficiencies or irregularities. Use carefully controlled sand blasting, approved grinding equipment, or other approved method to remove marking so that the surface to which the marking was applied will not be damaged.

3.03 PROTECTION
A. Conduct operations in such a manner that necessary traffic can move without hindrance.

Protect the newly painted markings so that, insofar as possible, the tires of passing vehicles will not pick up paint. Place warning signs at the beginning of the wet line, and at points well in advance of the marking equipment for alerting approaching traffic from both directions. Place small flags or other similarly effective small objects near freshly applied markings at frequent intervals to reduce crossing by traffic. Efface and replace damaged portions of markings at no additional cost to the Owner.

3.04 DETAIL PAVEMENT MARKING
A. Use Detail Pavement Markings, exclusive of actual traffic lane marking, at exit and entrance islands and turnouts, on curbs, at crosswalks, at parking bays, and at such other locations as shown. Show the International Accessibility Symbol at indicated parking spaces. Color shall be as shown. Apply paint for the symbol using a suitable template that will provide a pavement marking with true, sharp edges and ends. Place detail pavement markings of the color(s), width(s) and length(s), and design pattern at the locations shown.

3.05 FINAL CLEAN-UP
A. Remove all debris, rubbish and excess material from the site.

C. Color: Yellow conforming to Federal Color No. 33538. Color shall be homogeneous throughout the tile.

PART 3 EXECUTION

3.01 INSTALLATION
A. During Cast In Place Detectable/Tactile Warning Surface Tile installation procedures, ensure adequate safety guidelines are in place and that they are in accordance with the applicable industry and government standards.

B. Prior to placement of the Cast In Place Detectable/Tactile Warning Surface Tile system, review manufacturer and contract drawings with the Contractor prior to the construction and refer any and all discrepancies to the Engineer.

C. The specifications of the structural embedment flange system and related materials shall be in strict accordance with the contract documents and the guidelines set by their respective manufacturers. Not recommended for asphalt applications.

D. The physical characteristics of the concrete shall be consistent with the contract specifications while maintaining a slump range of 4 - 7 to permit solid placement of the Cast In Place Detectable/Tactile Warning Surface Tile system. An overly wet mix will cause the tile to float.

Under these conditions, suitable weights such as 2 concrete blocks or sandbags (25 lb) shall be placed on each tile.

E. The concrete pouring and finishing operations require typical mason’s tools, however, a 4’ long level with electronic slope readout, 25 lb. weights, and a large non-marring rubber mallet are specific to the installation of the Cast In Place Detectable/Tactile Warning Surface Tile system. A vibrating mechanism such as that manufactured by Vibco can be employed, if desired. The vibrating unit should be fixed to a soft base such as wood, at least 1 foot square.

F. The factory-installed plastic sheeting must remain in place during the entire installation process to prevent the splashing of concrete onto the finished surface of the tile.

G. When preparing to set the tile, it is important that no concrete be removed in the area to accept the tile. It is imperative that the installation technique eliminates any air voids under the tile. Holes in the tile perimeter allow air to escape during the installation process.

Concrete will flow through the large holes in each embedment flange on the underside of the tile. This will lock the tile solidly into the cured concrete.

H. The concrete shall be poured and finished true and smooth to the required dimensions and slope prior to the tile placement. Immediately after finishing concrete, the electronic level should be used to check that the required slope is achieved. The tile shall be placed true and square to the curb edge in accordance with the contract drawings. The Cast In Place

SECTION 32 17 26 CAST-IN-PLACE DETECTABLE/TACTILE WARNING SURFACE CAST-IN-PLACE DETECTABLE/TACTILE WARNING SURFACE 32 17 26 - 5 of 6 Detectable/Tactile Warning Surface Tiles shall be tamped (or vibrated) into the fresh concrete to ensure that the field level of the tile is flush to the adjacent concrete surface. The embedment process should not be accomplished by stepping on the tile as this may cause uneven setting which can result in air voids under the tile surface. The contract drawings indicate that the tile field level (base of truncated dome) is flush to adjacent surfaces to permit proper water drainage and eliminate tripping hazards between adjacent finishes.

I. In cold weather climates it is recommended that the Cast In Place Detectable/Tactile Warning Surface Tiles be set deeper such that the top of domes are level to the adjacent concrete on the top and sides of ramp and that the base of domes to allow water drainage. This installation will reduce the possibility of damage due to snow clearing operations.

J. Immediately after placement, the tile elevation is to be checked to adjacent concrete. The elevation and slope should be set consistent with contract drawings to permit water drainage to curb as the design dictates. Ensure that the field surface of the tile is flush with the surrounding concrete and back of curb so that no ponding is possible on the tile at the back side of curb.

K. While concrete is workable, a 3/8" radius edging tool shall be used to create a finished edge of concrete, then a steel trowel shall be used to finish the concrete around the tile’s perimeter, flush to the field level of the tile.

L. During and after the tile installation and the concrete curing stage, it is imperative that there is no walking, leaning or external forces placed on the tile that may rock the tile causing a void between the underside of tile and concrete.

M. Following tile placement, review installation tolerances to contract drawings and adjust tile before the concrete sets. Two suitable weights of 25 lb each may be required to be placed on each tile as necessary to ensure solid contact of the underside of tile to concrete.

N. Following the concrete curing stage, protective plastic wrap is to be removed from the tile surface by cutting the plastic with a sharp knife, tight to the concrete/tile interface. If concrete bled under the plastic, a soft brass wire brush will clean the residue without damage to the tile surface.

O. If desired, individual tiles can be bolted together using ¼ inch or equivalent hardware. This can help to ensure that adjacent tiles are flush to each other during the installation process.

Tape or caulking can be placed on the underside of the bolted butt joint to ensure that concrete does not rise up between the tiles during installation. Any protective plastic wrap which was peeled back to facilitate bolting or cutting, should be replaced and taped to ensure that the tile surface remains free of concrete during the installation process.

P. Tiles can be cut to custom sizes, or to make a radius, using a continuous rim diamond blade in a circular saw or mini-grinder. Use of a straightedge to guide the cut is advisable where appropriate.

Q. Any sound-amplifying plates on the underside of the tile, which are dislodged during handling or cutting, should be replaced and secured with construction adhesive. The air gap created between these plates and the bottom of the tile is important in preserving the sound on cane audible properties of the Armor-Tile system as required in various jurisdictions.

3.02 CLEANING, PROTECTING AND MAINTENANCE
A. Protect tiles against damage during construction period to comply with Tactile Tile

SECTION 32 17 26 CAST-IN-PLACE DETECTABLE/TACTILE WARNING SURFACE CAST-IN-PLACE DETECTABLE/TACTILE WARNING SURFACE 32 17 26 - 6 of 6 manufacturer’s specification.

B. Protect tiles against damage from rolling loads following installation by covering with plywood or hardwood.

C. Clean Tactile Tiles not more than four days prior to date scheduled for inspection intended to establish date of substantial completion in each area of project. Clean Tactile Tile by method specified by Tactile Tile manufacturer.

D. Comply with manufacturers maintenance manual for cleaning and maintaining tile surface and it is recommended to perform annual inspections for safety and tile integrity.

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 18 of 26
All necessary test equipment shall be in proper working order and tests shall be made in the presence of the Inspector. Test plugs shall be carefully placed at each end of the section of line to be tested. When all necessary test equipment is in place, a compressed air supply shall be attached to the air fitting on the test equipment and the air pressure within the line increased to 4 psi. After the air supply is securely turned off or disconnected, there shall be a 2-minute waiting period to allow stabilization of air within the sewer line before the actual test period begins. In no case shall the air pressure within the line be less than 3-1/2 psi at the beginning of the test period. The allowable air pressure loss shall not exceed 1 psi. When testing side sewers, or portions thereof, the test period shall be 4 minutes and the allowable loss shall not exceed 1 psi. After completion of a test, the air pressure shall be released slowly through the valve, which is incorporated in the test equipment. Air test plugs shall not be removed until the air pressure is no longer measurable.

C. New sewers larger than 16” diameter shall be hydrostatically tested in accordance with the following procedure:

1. After installation, all new trunk sewer pipelines shall be thoroughly cleaned prior to pressure testing. A section of trunk sewer shall be prepared for testing between two structures by plugging the inlet side of the discharge manhole and all openings in the upstream manhole except the discharge opening. All plugs shall be properly braced against the manhole wall to withstand the forces of the test in order to prevent loss in the event of a failure.

2. A section of the trunk sewer prepared as above shall be tested by filling it with water to an elevation 5 feet above the top of pipe at the upstream end of the test section, or 5 feet above the existing groundwater elevation, whichever is greater. The water shall be introduced into the test section at least one hour in advance of the test period and refilled as necessary prior to commencement of the test period to allow the pipe and joint material to become saturated. The loss in water may be determined by measuring the rate of fall of the water level, but the level shall not be allowed to fall more than one foot below the specified head during the test period.

3. For RCP, the pressure shall be maintained for not less than 4 hours and the leakage rate shall not exceed 200 gallons per inch of diameter per mile of pipe for 24 hours (ASTM C 969-02). For VCP, the pressure shall be maintained for not less than one hour and the leakage rate shall not exceed 200 gallons per inch diameter per mile for 24 hours (ASTM C 1091-03a). For DIP, the pressure shall be maintained for not less than one hour and the leakage rate shall not exceed 70 gallons per inch diameter per mile of pipe of 24 hours (AWWA C600-54T).

D. When leakage exceeds the amount allowed by the specifications, the Contractor shall locate the leaks, submit a repair procedure for the Inspector’s review, and make the necessary repairs.

3.05 MANHOLE TESTING:

A. Hydrostatic Testing: Central San may require hydrostatic testing for leakage after installation and prior to backfilling. Prior to hydrostatic testing, all manholes shall be visually inspected. All defects shall be repaired by the Contractor, with non-shrink grout, to the satisfaction of the Inspector. All pipes entering the manhole shall be sealed at a point outside the manhole walls to include testing of the pipe/manhole joints. Safety lines shall be secured to all plugs utilized. The manhole shall be filled with water to a level 2” below the top of the frame. After a period of at least one hour to allow the water level to stabilize, the manhole shall be refilled and the water level shall be checked. The water level shall again be checked after a period of 4 hours. If the water level drops by more

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 19 of 26
than 1”, the leakage shall be considered excessive, and the Contractor shall make necessary repairs and retest the manhole.

B. Vacuum Testing: As an alternative to manhole hydrostatic testing, the Inspector may allow the use of vacuum testing. A vacuum of 10” of mercury shall be drawn on the manhole, the valve on the vacuum line of the test hood closed and the vacuum pump shut off. The manhole shall be deemed to have passed the test if the vacuum drop is less than 1” of mercury during a one-minute test period.

3.06 CCTV INSPECTION:

A. Central San will perform a CCTV inspection of the sanitary sewer upon substantial completion of the work.

1. The Contractor shall coordinate with the Inspector to arrange for an acceptable time to conduct the inspection.

2. Defects discovered by the CCTV inspection shall be corrected and the line reinspected at the Contractor’s cost.

3. If a portion of an entire job is to be CCTV inspected, a separate fee will be due as established by Central San. Inspection fees are payable prior to the date of the partial CCTV inspection.

4. The Contractor shall request CCTV inspection once the following have been completed:
a) Sewer pipelines are installed, backfilled, and compacted. b) Structures are in place, channeling is complete, and pipelines are accessible from structures.
c) All other underground facilities, utility piping, and conduits in the vicinity are installed.
d) For street locations, placement of aggregate base has been completed. e) Pipelines to be inspected have been cleaned and flushed. f) Final pressure test has been completed.
g) Mandrel testing is complete.

B. The procedure outlined below will be repeated until all deficiencies observed by CCTV inspection have been corrected to the satisfaction of Central San.

1. The Contractor shall request Central San to schedule the CCTV inspection. a) If Central San's CCTV crew arrives at the jobsite and the work is not ready or accessible, the Contractor will be billed the cancellation fee payable to Central San prior to the date of rescheduled CCTV inspection. The Contractor shall reschedule CCTV inspection as outlined above.

2. Central San will televise the job.

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 20 of 26

A. Temporary Plugs

1. Mechanical expanding-type temporary plugs shall be installed and removed, as specified below, in the presence of an Inspector. Plugs shall be secured by tethering with a ¼” nylon rope attached to the top of a wood 2’x4’ of sufficient length to extend from the shelf to a point in the throat within 6” of the underside of the cover.

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 23 of 26
a) When a manhole exists or a new manhole is constructed at the beginning of a new main extension, a temporary plug shall be installed at the inlet of the new pipe at the existing manhole or new manhole.
b) When a new main extension begins at an existing rodding inlet or stub, a temporary plug shall be installed on the outlet of the first manhole upstream from the beginning of the new main extension.

B. Cast-in-Place Manhole Bases

1. Cast-in-place manhole bases over existing sewers shall be poured against undisturbed native soil, which has been excavated to the dimensions shown on the Plans. For new sewer installations, the cast-in-place manhole base shall be poured over 6” Type 1 Backfill. See DWG 19-01 through 19-08. If the excavation extends beyond the dimensions shown on the Standard Drawings, the Contractor shall construct forms and pour the base to the specified dimensions.

2. If water or soft ground is encountered at the bottom of the excavation, a minimum lift of 9” of coarse-bedding material in a geotextile wrap shall be used as shown on DWG 19-01.

3. A joint forming ring shall be used to form a level joint groove in the manhole base while the concrete is fresh to receive the first precast barrel section. The metal forming ring may be removed as soon as the concrete has set sufficiently to eliminate any slump in the joint groove.

4. Manhole channels shall be shaped to form a smooth transition from inlet pipes to the outlet pipe, both horizontally and vertically.

C. Precast Manhole Bases (on all new main sewer extensions)

1. Precast manhole bases shall be placed to the lines and grades shown on the Plans as an integral part of the pipe laying operation on a minimum thickness of 6” of Type I Bedding and Backfill Material compacted to 95% relative compaction. Where soft ground or water is present, a minimum thickness of 9“ of Coarse Bedding Material in a wrap of geotextile, per the requirements of Section 31 05 19 - Geosynthetics for Earthwork, shall be placed below the course of Type I Bedding and Backfill Material.

2. Inlet and outlet pipe connections at precast bases shall be pipe bells cast into the base by the manufacturer.

3. All precast concrete manholes shall be installed in strict conformance with the manufacturer's written instructions on a well-compacted foundation.

D. Setting Precast Barrel and Cone Sections

1. All joint surfaces of precast manhole bases, barrel and cone sections shall be thoroughly cleaned and dried prior to setting, and shall be sealed with a preformed plastic sealing gasket listed in the Approved Materials List at each joint as follows:
a) Remove the paper wrapper from one side of the gasket, retaining the outside paper in place to protect the gasket and assure against stretching. b) Place the plastic gasket strip in the joint, forming a continuous gasket around the entire circumference of the manhole joint.

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 24 of 26
c) Remove the paper wrapper from the exposed side of the gasket and place the next manhole component.
d) Care shall be taken in the handling of barrel and cone sections after the plastic gasket has been affixed to avoid displacing the gasket or contaminating the joint or gasket with dirt or other foreign material. Any displaced or soiled gaskets shall be removed and replaced.
e) Care shall be taken to properly align the manhole section with the previously set section before it is lowered into position.
f) During cold or wet weather, the joint surfaces shall be heated with hot air until ice, frost, and moisture are removed and surface to be primed is dry and warm.

Hot air shall also be passed over plastic gasket strips immediately prior to attaching them to joint surfaces and immediately prior to setting the section.

E. Manhole frames and covers shall not be set to final grade until the pavement has been completed, unless otherwise approved by Central San. Precast concrete grade rings shall be installed as shown in the Standard Drawings. Paving around the manhole shall be in accordance with local jurisdiction requirements. Openings in manholes shall be protected from construction loads, debris and unauthorized entry.

F. When new piping is installed in existing structures, the Contractor shall accurately position core-drilled openings in the concrete as shown on the job Plans and Standard Drawings or otherwise directed by the Inspector. Openings shall be of sufficient size to permit a final alignment of pipelines and fittings without deflection of any part and to allow adequate space for satisfactory placement of mechanical seals or packing with nonshrink grout where the pipe passes through the wall to ensure the resulting structure is watertight. Before placing the non-shrink grout, concrete surfaces shall be sandblasted, thoroughly cleaned of sand and any other foreign matter, and coated with epoxy bonding compound. After connection of the new inlet pipe, the Contractor shall re-channel the inside of the existing manhole base to provide a smooth flow channel to the new exit pipe.

G. The throat shall be constructed using appropriately sized reinforced concrete grade rings to bring the manhole cover to finished grade surface. No plastic sealing gaskets shall be used for jointing grade or extension rings.

H. Manhole top blocks shall be poured against forms constructed to the specified dimensions shown on DWG 19-01.

I. All manholes located on slopes steeper than 3:1 (horizontal to vertical) in easement areas shall be constructed with a reinforced concrete, reinforced concrete masonry unit or interlocking masonry unit retaining wall as shown on DWG 19-11.

J. All manholes shall be tested in accordance with Section 33 01 30.11 - Inspection of Sewers.

K. Temporary covers shall be used during construction until permanent frames and covers are installed.

3.03 RECONSTRUCTION OF EXISTING STRUCTURES:

A. General

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 25 of 26

1. Reconstruction work on any particular structure shall be diligently prosecuted so as to be completed within 3 calendar days after work is begun on that particular structure.

The Contractor shall provide continuous access for Central San maintenance forces to the structure at all times.

2. When removing existing structures, the Contractor shall take precautions to ensure that no foreign material enters the structure or the downstream system. Before any work is started, the base shall be covered with a plywood (“false bottom”) as shown on DWG 19-13, and then the false bottom shall be covered with a drop cloth of heavy canvas. The drop cloth and false bottom shall be kept in place during the work to catch debris, and upon completion, shall be removed with the collected debris. No debris shall enter the downstream system or be allowed to remain in the manhole.

B. Structure Adjustments and Repairs

1. All workmanship and materials for structure adjustments shall conform to the requirements of these Specifications. In the case of existing brick or cast-in-place concrete structures, repair or adjustments shall be accomplished with materials in-kind or with precast elements as detailed on the Plans.

2. Existing structure precast elements, adjustment rings, frames, and covers removed for adjustments and/or repairs may be reinstalled only when such undamaged items are permitted by the Inspector for reuse.

3. Manhole adjustments shall be accomplished by one of the methods specified below or as shown on the Plans:
a) Upward adjustments of manholes to finish grade surface may be accomplished with reinforced concrete grade rings, formed concrete and/or a single cast iron extension ring when the adjusted manhole throat will not exceed 12” in height. In no case shall multiple cast iron extension rings be used in adjustments. When adjustments are made that position the bottom of the cast iron manhole frame above the existing concrete top block, the top block shall be reconstructed in accordance with the requirements of DWG 19-01 through 19-08. b) Whenever upward adjustment of manholes would result in a completed manhole throat section exceeding 12” in height, the upper manhole section, including the top block and cone section, shall be removed and the adjustment shall be made by reconstructing the structure using manhole barrel and cone sections, grade rings and frames and covers in accordance with the requirements of these Specifications and DWG 19-01 through 19-08.
c) Downward adjustments of manholes shall be accomplished by removal of existing grade or extension rings and cone and barrel sections as required, and reconstructing the structure using manhole barrel and cone sections, grade rings and frames and covers in accordance with the requirements of these Specifications and DWG 19-01 through 19- 08.

4. Rodding inlet adjustments shall be accomplished by one of the methods specified below or as detailed on the Plans:
a) Upward adjustments of rodding inlets shall be accomplished with formed concrete or cast-iron extension rings where the extension will not exceed 8”, including any previous adjustments. When adjustments are made that position the bottom of the cast iron frame above the existing concrete top block, the top

SECTION 33 30 00 SANITARY SEWER UTILITIES
SANITARY SEWER UTILITIES 33 30 00 - 26 of 26
block shall be reconstructed in accordance with the requirements of these Specifications and DWG 19-14.
b) Upward adjustments of rodding inlets exceeding 8” shall be accomplished by removing the structure’s frame, cover, and top block, and reconstructing the structure in accordance with the requirements of these Specifications and DWG 19-14. Pipe used for such adjustments shall be as required for pipeline repair and shall be installed to extend the line and grade of the existing pipe. c) Downward adjustments of rodding inlets shall be accomplished by removal and reconstructions of the entire upper section of the structure including the top block.

2. Budget Schedule Diagram 2025-26 - Council Ready
Summary: The Council will receive and consider the City's operating and capital budget development and adoption schedule for the 2025-26 fiscal year (abbreviated as 2026).

Background: California's law requires that an annually-approved appropriation plan be considered for all local governmental entities. Most produce a budget to satisfy that requirement. The City of Ukiah will develop a budget document for the 2026 fiscal year built on best practices, focused on clarity, and presented at the highest level of quality per the guidelines of the Government Finance Officers Association.

Discussion: A sound, well-managed budget for a governmental entity is a living document. It is subject to regular review and amendment, is clear and understandable, is scrutinized frequently, and its development thoughtfully planned and executed. The City of Ukiah’s 2026 budget will exhibit these characteristics, starting with planning. Attachment 1, Budget Development Schedule 2025-26, outlines the development process, key dates, and milestones. It is principally a management document. A summarized version highlighting the major events by month is attached as Attachment 2.

Note: This schedule is flexible and currently in draft. It may be revised as necessary. Council members should review and hold dates/times on their calendar. Council members should also report any potential conflicts to Dan Buffalo, Director of Finance.

Recommended Action: Receive and consider the City's operating and capital budget development and adoption schedule for the 2025-26 fiscal year.

AGENDA SUMMARY REPORT
SUBJECT: Possible Introduction of Ordinance by Title Only Amending the City Code Provisions Regarding Enforcement of Business License Regulations.

DEPARTMENT: Community
Development PREPARED BY: Darcy Vaughn, Assistant City Attorney PRESENTER: Craig Schlatter, Community Development
Director; Darcy Vaughn, Assistant City Attorney
ATTACHMENTS:

1. Business License Enforcement Authority Ordinance Redline

2. Business License Enforcement Authority Ordinance Clean Summary: Council will consider introducing by title only an Ordinance amending Article 6 in Division 2, Chapter 1 of the Ukiah City Code to allow the Director of Finance to delegate enforcement authority for the City's business license regulations to the Chief Code Enforcement Official, in addition to the Chief of Police.

Background: Division 2, Chapter 1 of the City Code sets forth requirements and regulations for businesses operating in the City of Ukiah to obtain and renew business licenses. The vast majority of these provisions were adopted in 1961 and few have been updated since their adoption. Prudent management practices require a periodic review of these provisions to consider potentially beneficial additions, amendments, or deletions of provisions as may be deemed necessary. As part of the larger review of these provisions undertaken by the Community Development Department, Staff determined that while enforcement authority over the business license requirements and regulations is properly given to the Director of Finance, as business licenses are deemed a tax by case law, the Code Enforcement Division of the Community Development Department may be better equipped to efficiently enforce these provisions as part of their general code enforcement authority.

Article 6 of Division 2, Chapter 1, which contains the enforcement provisions for business licenses, currently authorizes the Director of Finance to delegate enforcement authority only to the Chief of Police and states that assistants of the Director, including police officers, may conduct inspections of businesses to determine whether a place of business is operating with a current and valid business license. Staff recommends that these provisions be amended via ordinance ("Ordinance") to allow the Director of Finance to delegate enforcement authority to the Chief Code Enforcement Official and to authorize code enforcement officers to conduct business license inspections.

Discussion: The Ordinance, attached hereto as Attachment 1 (Redline) and Attachment 2 (Clean) amends Section 2170 of the City Code to state that the Director of Finance has the duty to enforce all provisions of Division 2, Chapter 1 regarding business license regulations, and that the Chief Code Enforcement Official, in addition to the Chief of Police, are directed to assist the Director in enforcement as may be required. This Section is also amended to state that every staff member in the Code Enforcement Division of the Community Development Department is appointed an Assistant License Inspector and directed to assist the Director of Finance in the enforcement of Division 2, Chapter 1.

In addition, the Ordinance amends Section 2171 of the City Code to state that code enforcement officers are authorized to act as assistants of the Director of Finance in fulfilling his duty to examine each business to

confirm compliance with the business license requirements and regulations.

Staff recommends Council introduce the Ordinance in Attachment 2 by title only, which would amend the City Code provisions regarding enforcement of business license regulations.

Recommended Action: Introduce by title only the Ordinance amending the City Code provisions regarding enforcement of business license regulations.

AGENDA SUMMARY REPORT
SUBJECT: New Year Review, Discussion, and Appointments Regarding 2025 Council Assignments; and Consideration of Disbandment and Modification to City Council Committees and Ad Hocs/Standing Committees.

DEPARTMENT: City Clerk PREPARED BY: Kristine Lawler, City Clerk PRESENTER: Mayor Crane and City Manager Sangiacomo
ATTACHMENTS:

1. Draft 2025 City Council Special Assignments
Summary: City Council members will provide reports and updates on their committee and ad hoc/standing committee assignments.

Each year following the rotation of the mayor position, the incoming mayor leads a review of assignments. The Council will also consider modifications, additions and elimination of committee and ad hocs/standing committees.

Background: Local / County / Regional Committees - City of Ukiah Councilmembers take an active role in various commissions and committees that are part of city, county, regional, and statewide governance and interests. Each year, the incoming mayor leads a discussion and makes annual appointments for members assigned to various committee assignments. Committee assignments are organized into Local / County / Regional classifications. Roles on committee assignments will vary from liaison to a voting board seat. Assignments are typically filled by a Councilmember, but in some cases it may be appropriate or desired to appoint a Staff member. In some instances, there might be a primary and alternate designated for assignment.

Ad Hoc and Standing Committees - The City Council may establish and appoint ad hoc and standing committees at any time throughout the year. Ad Hocs are established on an as needed, temporary basis for the purpose of addressing particular issues and will disband once the work is complete. Standing Committees are established for the purpose of addressing broader and/or ongoing issues and are subject to the Brown Act meeting noticing requirements.
***Note: Although the Council Ad Hoc and Standing Committees are a part of the Council Special Assignment List, they are officially appointed by the Council at various meetings, and are subject to Council approval for any changes.

Discussion: Attachment #1 is a draft of the 2025 Council Special Assignment List and Ad Hoc Committees, inclusive of recommended changes - delineated by added text and strike-through edits in red for vacated positions and Council request. Mayor's recommendations are in green. In addition, ad hoc committees highlighted in red are recommended by Staff for disbandment.

The Mayor will lead a discussion with Council regarding Council committee assignments and make any appointments or reassignments per that discussion. In addition, the Council will consider modifications, additions and disbandment of ad hocs and standing committees. Staff recommends directing the City Clerk to

attach the finalized copy of the 2025 City Council Special Assignments List to the January 15, 2025, minutes for recordation.

Note: All subsequent agendas throughout the year will have a continuation item to allow Council to receive reports on committee and ad hoc work and to allow for further modifications (including the addition of any new ad hocs) as warranted.

Recommended Action: 1) Receive report(s); 2) Discuss the Mayor's recommended assignments, making any possible appointments or re-assignments; 3) Consider the possible continuation, disbandment, and addition of City Council Ad Hoc and/or committees; and 4) Direct the City Clerk to finalize and attach the 2025 Council Assignments and Ad Hoc/Standing Committees List to the January 15, 2025, Minutes.
