1.0 INTRODUCTION AND SITE SETTING
The proposed project will consist of a neighborhood park to be located on Broad Street, where the Broad Street community garden currently resides, in San Luis Obispo, California (see Figure 1 – Site Vicinity Map in Appendix A). Based on the preliminary plans, the proposed neighborhood park will include new pedestrian flatwork, a new shade structure, new playground structures, decorative fencing, and miscellaneous structures such as picnic bench and table areas.
We understand the new playground and miscellaneous structures as well as the new shade and signage structures will be supported by conventional shallow foundations. We have provided separate shallow foundation recommendations for the playground/miscellaneous structures and the shade/signage structures. Dead plus live column loads were not provided for the shade and signage structures but are anticipated to be on the order of 500 psf. Site improvements will include Portland cement concrete (PCC), exterior flatwork, and landscaping. No stormwater control measures (SCMs), basements, retaining walls or subterranean structures are anticipated.
The site is currently used as a community garden with multiple raised and in-ground garden beds, and a few non-permanent picnic tables. The site is located at the approximate coordinates of latitude 35.2841N and longitude 120.6684W, which were obtained from the Google Earth Website (Google Earth 2022). The site is relatively flat. The site is surrounded by Broad Street to the northeast, residential units to the southwest, and descending slopes leading to creeks on the southeast and northwest bounds of the site.
2.0 SCOPE OF SERVICES
The authorized scope of work included a general site reconnaissance, field exploration, geotechnical analysis of the data gathered, and preparation of this report. The analysis and subsequent recommendations were based on verbal information and a general project location plan provided by the client.
This report and recommendations are intended to comply with the considerations of Sections 1803.1 through 1803.6, J104.3 and J104.4, as applicable, of the 2019 California Building Code (CBC) and common geotechnical engineering practice in this area under similar conditions at this time. The test procedures were accomplished in general conformance with the standards noted, as modified by common geotechnical engineering practice in this area under similar conditions at this time.

Preliminary geotechnical engineering recommendations for site preparation, grading, foundations, flatwork, drainage, and observation and testing are presented to guide the development of project plans and specifications. As there may be geotechnical issues yet to be resolved, the geotechnical engineer should be retained to provide consultation as the design progresses. It may also be advantageous to retain the geotechnical engineer to review project plans as they near completion to assist in verifying that pertinent geotechnical issues have been addressed and to aid in conformance with the intent of this report.
It is our intent that this report be used exclusively by the client to form the geotechnical basis of the design of the project and in the preparation of plans and specifications. Application beyond this intent is strictly at the user’s risk.
This report does not address issues in the domain of contractors such as, but not limited to, site safety, loss of volume due to stripping of the site, shrinkage of soils during compaction, excavatability, dewatering, temporary slope angles, construction means and methods, etc.
Analyses of aerial or site geology, or of the soil for corrosivity, radioisotopes, asbestos (either naturally occurring or in man-made products), lead or mold potential, hydrocarbons, or chemical properties is beyond the scope of this report. Any ancillary features such as flag or light poles, temporary access roads, non-structural fills, and vehicular pavements are not within our scope and are also not addressed. Design and/or suitability of LID features such as retention basins, bio swales, or other improvements are also beyond our scope.
In the event that there are any changes in the nature, design, or location of improvements, or if any assumptions used in the preparation of this report prove to be incorrect, the conclusions and recommendations contained in this report shall not be considered valid unless the changes are reviewed and the conclusions of this report modified or verified by the geotechnical engineer in writing. The criteria presented in this report are considered preliminary until such time as any peer review or review by any jurisdiction has been completed, conditions have been observed by the geotechnical engineer in the field during construction, and the recommendations have been verified as appropriate, or modified by the geotechnical engineer in writing.
3.0 FIELD INVESTIGATION AND LABORATORY ANALYSIS
On August 17, 2022, two exploratory boring was drilled on site to depths ranging from approximately 11.5 feet and 16.5 feet below the existing ground surface (bgs). The boring was drilled with a truck-mounted SIMCO EP200 drill rig equipped with a 4-inch outside diameter solid
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 3 2209-067.SER
stem auger and an automatic hammer for sampling. As the boring was advanced, a soil sample was obtained using a 3-inch outside diameter ring-lined barrel sampler (ASTM D 3550-17 with shoe similar to ASTM D 2937-17). Bulk samples were also obtained from the auger cuttings. The approximate locations of the borings are shown on Figure 2 – Exploration Location Map in Appendix A.
Soils encountered in the borings were categorized and logged in general accordance with the Unified Soil Classification System and ASTM D 2488-17. Logs of the borings are presented in Appendix A, along with a Boring Log Legend. In reviewing the boring logs and legend, the reader should recognize that the legend is intended as a guideline only, and there are a number of conditions that may influence the characteristics observed during drilling. These include, but are not limited to, the presence of cobbles or boulders, cementation, variations in soil moisture, presence of groundwater, and other factors. Consequently, the logger must exercise judgment in interpreting soil and bedrock characteristics, possibly resulting in soil or bedrock descriptions that vary from the legend.
One bulk sample was tested for maximum density and optimum moisture content (ASTM D 1557- 12, modified) and expansion index (ASTM D 4829-11). Three ring samples were tested for bulk density (ASTM D 2937-17, modified for ring liners) and moisture (ASTM D 2216-10). One ring sample was tested for direct shear (ASTM D 3080/D 3080M-11) and one was tested of one dimensional consolidation (ASTM D 2435/2435M-11). The results of the laboratory tests are presented in Appendix B.
4.0 GENERAL SUBSURFACE
Similar conditions were found in both borings. Alluvium was encountered at the surface and extended to the maximum depth explored of 16.5 feet bgs. The alluvium consisted of sandy fat clay to a depth of approximately 14 feet bgs at which point sandy lean clay was encountered. The sandy fat clay had a medium stiff to very stiff consistency; the sandy lean clay was medium stiff.
The alluvium was logged as being slightly moist to very moist. Groundwater was not encountered in the borings. Please refer to the boring logs in Appendix A for a more complete description of the subsurface conditions encountered at the site.
5.0 CONCLUSIONS
In our opinion, the site is suitable, from a geotechnical engineering standpoint, for the proposed project, provided the recommendations contained herein are implemented in the design and
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 4 2209-067.SER
construction. From a geotechnical engineering standpoint, the primary concerns at the site are the potentials for strong ground shaking and the presence of expansive surficial soils. The potential for liquefaction is also discussed below.
Potential Strong Ground Shaking
The site is in a region of high seismic activity with the potential for large seismic events that could generate strong ground shaking. The CBC requires that seismic loads be considered in structural design. A seismic analysis was undertaken to provide seismic acceleration design parameters; the results are presented in the “Foundations” section of this report for use by others in the structural design process.
The 2010 ASCE 7 method with 2013 updates available on the Structural Engineers Associate of California (SEAOC) Seismic Design Map Tool website (SEAOC, 2021) was used for the seismic analysis. The risk category for buildings and structures is assigned by others in accordance with CBC Table 1604.5; however, based on our current understanding of the project, we selected Risk Category II for our analysis. Based upon the subsurface conditions encountered during our subsurface investigation, Site Class “D,” “Stiff Soil,” was used. A general ground motion seismic analysis was performed, assuming that Exception 2 listed in Section 11.4.8 (ASCE, 2017) will apply to the project. We also provided seismic parameters if the Simplified Lateral Force Analysis Procedure from Section 12.14.8 (ASCE, 2017) will be used in structural design.
Presence of Expansive Surficial Soils
Expansion index testing performed on a bulk sample of the near surface soils resulted in a value of 158, which indicates the soils are highly expansive. Expansive soils tend to swell with seasonal increases in moisture and shrink during the dry season as subsurface moisture decreases. The volume changes that these materials undergo in this cyclical pattern can stress and damage slabs and foundations if precautionary measures are not incorporated into the design and construction procedures. Footings are typically deepened, and additional reinforcement is added. Imported non-expansive soils are recommended to be placed beneath exterior flatwork.
Liquefaction Potential
Liquefaction refers to a phenomenon that tends to occur in saturated soils of low density that have grain sizes within a certain range, usually fine- to medium-grained poorly graded sands, silty sands, and sandy silts. A sufficiently strong earthquake is also required to cause liquefaction.
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 5 2209-067.SER
During liquefaction, the energy from the earthquake causes the water pressure within the pores of the soil to increase. The increase in water pressure decreases the friction between the soil grains, allowing the soil grains to move relative to one another. During this state, the soil will behave as a viscous liquid, temporarily losing its ability to support foundations and other improvements. As the pressure is released, the soils typically settle in a process called “liquefaction settlement.” Liquefaction settlement can cause damage to structures and other surface and subsurface improvements if their potential is not addressed. The soils encountered at the site were classified as sandy fat clay and sandy lean clay. Clay soils such as those encountered at the site are unlikely to liquefy if encountered below the groundwater.
Groundwater was not encountered at a maximum depth of 16.5 feet bgs. Although the site is mapped by the County of San Luis Obispo (2013) as being in an area of moderate liquefaction potential, it is our opinion that there is minimal potential for liquefaction at the project site due to the presence of the clay soils and to the lack of groundwater at the maximum depth explored.
6.0 GEOTECHNICAL RECOMMENDATIONS
These recommendations are applicable for the improvements as described in the “Introduction and Site Setting” Section of this report. If other improvements not previously mentioned are included, the geotechnical engineer should be contacted for revised recommendations.
Unless otherwise noted, the following definitions are used in the recommendations presented below. Where terms are not defined, definitions commonly used in the construction industry are intended.
• Foundation Areas – The areas within the footprints of all conventional shallow (individual spread) foundations.
• Pedestrian Flatwork Areas: The footprint on any PCC flatwork that will accommodate pedestrian foot traffic only.
• Grading Area – The entire area to be graded, including the foundation areas, pedestrian flatwork areas, and any other areas to be graded.
• Subgrade: The elevation of the surface upon which a sand cushion/non-expansive imported material or aggregate base will be placed for flatwork or pavement improvements.
• Scarified: Thoroughly plowed or ripped in two orthogonal directions to a depth of not less than 8 inches.
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 6 2209-067.SER
• Moisture Conditioned: Soil moisture content adjusted to just above optimum moisture content prior to application of compactive effort.
• Compacted / Recompacted: Soils placed in level lifts not exceeding 8 inches in loose thickness and compacted to a minimum of 90 percent of maximum dry density, unless specified otherwise. The standard tests used to establish maximum dry density and field density should be ASTM D 1557-12 and ASTM D 6938-17, respectively, or other methods acceptable to the geotechnical engineer and jurisdiction.
Site Preparation
1. The ground surface in the foundation area or foundation area should be prepared for construction by removing the existing flatwork, debris, vegetation and other deleterious materials. Existing utility lines that will not remain in service should be either removed or abandoned. The appropriate method of abandonment will depend upon the type and depth of the utility. Recommendations for abandonment can be made as necessary.
2. Voids created by the removal of materials or utilities described above should be called to the attention of the geotechnical engineer. No fill should be placed unless the underlying soil has been observed by the geotechnical engineer.
Grading
Foundation Areas
1. Following site preparation, soils within the foundation areasshould be removed to a level plane at a minimum depth of the planned bottom-of-footing elevation. The exposed surfaces should then be scarified, moisture conditioned and recompacted.
Pedestrian Flatwork Areas
2. The soil in the exterior pedestrian flatwork areas should be overexcavated to a minimum depth of 2 foot below planned finished surface elevation. The soil surface exposed by overexcavation should be scarified, moisture conditioned, and recompacted. Imported non-expansive soil should then be placed in compacted lifts to subgrade elevation. Once subgrade is established and compacted, the placement, moisture conditioning, and compaction of aggregate base and any non-expansive soil can proceed. Non-expansive material is described below in paragraph 3.
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 7 2209-067.SER
3. Non-expansive soils are defined as falling into the GP, GW, GM, GC, SM, SC, SP, or SW categories (ASTM D 2487-17) and having an expansion index of 10 or less (ASTM D 4829- 19). Imported non-expansive soils used in the flatwork areas should have strength qualities equal to or better than the site soils. All proposed imported fill should be approved by the geotechnical engineer before being transported to the site and periodically during construction.
Grading – General
4. In the remainder of the grading area, prior to placement of fill or filling excavations to grade, the existing or excavated soil surfaces should be scarified, moisture conditioned, and recompacted.
5. Voids created by dislodging rocks and/or debris during scarification should be backfilled and compacted, and the dislodged materials should be removed from the work area.
6. All materials used as fill should be cleaned of all debris and any rocks larger than 6 inches in maximum dimension. When fill material includes rocks, the rocks should be placed in a sufficient soil matrix to ensure that voids caused by nesting of the rocks will not occur and that the fill can be properly compacted.
7. If the soils become unstable, or if the recommended compaction cannot be readily achieved, drying the soil to just above optimum moisture content may be necessary.
Placement of gravel layers or geotextiles may also be necessary to help stabilize unstable soils. If such conditions are found, the geotechnical engineer should be contacted to assist the contractor in selecting appropriate measures for stabilization of unstable soils.
8. The recommended soil moisture content should be maintained during construction and throughout the life of the project. Failure to maintain the soil moisture content can result in cracks and disturbance, which are an indication of degradation of the soil compaction.
If cracks are allowed to develop, or if soils near improvements such as foundations, flatwork, pavement, curbs, etc. are otherwise disturbed, damage to those improvements may result. Soils that have been or are otherwise disturbed should be removed, moisture conditioned, and compacted.

Foundations
Playground and Miscellaneous Structures
1. Conventional shallow continuous and spread footings may be used to support the proposed playground structures, picnic benches and tables. The footing excavations should be constructed with minimum depths of 18 inches below the lowest adjacent firm soil grade. Footing excavations should be cut neat and horizontal.
2. Continuous footings should be reinforced as required by the architect/engineer; minimum reinforcement should consist of one No. 4 rebar top and bottom. Spread footings should be reinforced in accordance with the requirements of the architect/engineer.
3. Footings bearing into native soils may be designed using maximum allowable bearing capacities of 1,000 psf for dead loads and 1,500 psf for dead plus live loads. Using these criteria, maximum settlement is expected to be less than 1 inch.
Shade, Signage, and Fencing Structures
4. Conventional shallow continuous and spread footings may be used to support the proposed shade structure, park entrance signage, and decorative fencing. The footing excavations should be constructed with minimum depths of 3 feet below the lowest adjacent firm soil grade. Footing excavations should be cut neat and horizontal.
5. Continuous footings should be reinforced as required by the architect/engineer; minimum reinforcement should consist of one No. 4 rebar top and bottom. Spread footings should be reinforced in accordance with the requirements of the architect/engineer.
6. Footings bearing into native soils may be designed using maximum allowable bearing capacities of 1,500 psf for dead loads and 2,000 psf for dead plus live loads. Using these criteria, maximum settlement and differential settlement are expected to be less than 1 inch over a horizontal distance of 25 feet.

7. In calculating resistance to lateral loads, a passive equivalent fluid pressure of 150 pcf in the soil may be used. Coefficient of friction for soil of 0.3 may also be utilized. Lateral capacity is based on the assumption that the soil adjacent to the foundation is undisturbed. In the case of foundations adjacent to native soils, the upper 1 foot and 2

305559-001 9 2209-067.SER
foot should be neglected in the design of the playground/miscellaneous structures and the shade/signage/fencing structures, respectively. Allowable bearing capacities may be increased by one-third when transient loads such as wind or seismicity are included.
8. The seismic acceleration site parameters included in the table below have been provided to the design team for use in its analyses. The 2010 ASCE 7 method with 2013 updates, available on the Structural Engineers Association of California website (SEAOC 2021), was used to obtain the parameters. The project was considered to be a “nonessential” facility from the perspective of risk category as described by the CBC. The site coordinates stated in the “Introduction and Site Setting” section were used in the analysis. Based upon the subsurface conditions encountered during our investigation, the site should be classified as Site Class D (Stiff Soil). Foundations may be designed using the following 2019 CBC seismic parameters.

9. Foundation excavations should be observed by the geotechnical engineer prior to placement of reinforcing steel. Soils in foundation excavations should be moistened to optimum moisture content, or just above, and no desiccation cracks should be present prior to concrete placement.
Exterior Pedestrian Flatwork
1. PCC pedestrian flatwork should have a minimum thickness of 4 full inches. Reinforcement size, placement, and dowels should be as directed by the architect/engineer; minimum pedestrian flatwork reinforcement should consist of No. 3 rebar placed at 24 inches oncenter each way.
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 10 2209-067.SER
2. Where maintaining the elevation of the pedestrian flatwork is critical, the flatwork should be doweled to the perimeter of adjacent improvements, at a minimum, by No. 3 dowels lapped to the flatwork rebar. In other areas, the flatwork may be doweled to the foundation or the flatwork may be allowed to “float free,” at the discretion of the architect/engineer. Flatwork that is intended to float free should be separated from foundations or other improvements by a felt joint or other means.
3. In addition to the placement of non-expansive material in the pedestrian flatwork areas as described in the “Grading” section, another measure that can be taken to reduce the risk of movement of flatwork due to expansive soils is to provide thickened edges or grade beams around the perimeters of the flatwork. The thickened edges or grade beams could be from 12 to 27 inches deep, with the deeper edges or grade beams providing better protection. At a minimum, the thickened edge or grade beam should be reinforced by two No. 5 rebar, one at the top and one at the bottom. The use of thickened edges or grade beams is left to the discretion of the city and/or architect/engineer.
4. To reduce shrinkage cracks in concrete, the concrete aggregates should be of appropriate size and proportion, the water/cement ratio should be low, the concrete should be properly placed and finished, contraction joints should be installed, and the concrete should be properly cured. Concrete materials, placement, and curing specifications should be at the direction of the architect/engineer; ACI 302.1R-15 is suggested as a resource for the architect/engineer in preparing such specifications.
Drainage and Maintenance
1. Unpaved ground surfaces should be graded during construction and, per Section 1804.3 of the CBC, finish graded to direct surface runoff away from foundations, slopes, and other improvements at a minimum 5 percent grade for a minimum distance of 10 feet. If this is not feasible due to the terrain, property lines, or other factors, swales with improved surfaces, area drains, or other drainage features should be provided to divert drainage away from these areas.
2. All eaves of the canopy should be fitted with roof gutters. Runoff from flatwork, roof gutters, downspouts, planter drains, area drains, etc. should discharge in a nonerosive manner away from foundations and other improvements in accordance with the requirements of the governing agencies. Erosion protection should be placed at all
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 11 2209-067.SER
discharge points unless the discharge is to an improved surface.
3. If soils are disturbed during construction, stabilization of soils by vegetation or other means, during and following construction, is essential to reduce erosion damage. Care should be taken to establish and maintain vegetation. The landscaping should be planned and installed to maintain the surface drainage recommended above. Surface drainage should also be maintained during construction.
4. Maintenance of drainage and other improvements is critical to the long-term stability of the site and the integrity of the structures. Site improvements should be maintained on a regular basis.
5. Finished flatwork surfaces should be sloped to freely drain toward appropriate drainage facilities. Water should not be allowed to stand or pond on or adjacent to exterior pedestrian flatwork, or other improvements as it could infiltrate into the sand/aggregate base or subgrade, causing premature deterioration of flatwork or other improvements.
6. All exterior drains and drain outlets should be maintained to be free-flowing. Care should be taken to establish and maintain vegetation. Vegetation and erosion matting (if utilized) should be maintained or augmented as needed. Irrigation systems should be maintained so that soils around structures are maintained at a relatively uniform year-round moisture content and are neither over-watered nor allowed to dry and desiccate.
7. To reduce the potential for disruption of drainage patterns and undermining of structures, fill areas, etc., all rodent activity should be aggressively controlled.
Observation and Testing
1. It must be recognized that the recommendations contained in this report are based on a limited number of borings and rely on continuity of the subsurface conditions encountered. Therefore, the geotechnical engineer should be retained to provide consultation during the design phase, to review plans as they near completion, to interpret this report during construction, and to provide construction monitoring in the form of testing and observation.
2. At a minimum, the geotechnical engineer should be retained to provide:
• Oversight of soil special inspection
City of San Luis Obispo North Broad Street Park October 4, 2022 San Luis Obispo, California
305559-001 12 2209-067.SER
3. Special inspection of grading and backfill should be provided as per Section 1705.6 and Table 1705.6 of the 2019 CBC. The special inspector should be under the direction of the geotechnical engineer. It is our opinion that none of the grading construction is of a nature that should warrant continuous special inspection; periodic special inspection should suffice. Subject to approval by the Building Official, the exception to continuous special inspection is described in Section 1704.2 of the 2019 CBC and should be specified by the architect/engineer and periodic special inspection of the following items should be provided by the special inspector.
• Conventional foundation excavations
4. A program of quality assurance should be developed prior to beginning construction. At a minimum, the program should include all geotechnical items shown on the testing and inspection schedule of the approved plans. It should also include any additional inspection items required by the engineer and/or the governing jurisdiction. These items should be discussed at a preconstruction site meeting among a representative of the owner, the geotechnical engineer, special inspector, the project inspector, the engineer, and contractors. The geotechnical engineer should be notified at least 48 hours prior to beginning grading operations.
5. Locations and frequency of compaction tests should be per the recommendation of the geotechnical engineer at the time of construction. The recommended test location and frequency may be subject to modification by the geotechnical engineer, based upon soil and moisture conditions encountered, size and type of equipment used by the contractor, the general trend of the results of compaction tests, or other factors.
6. A preconstruction conference among the owner, the geotechnical engineer, the governing agency, the special inspector, the project inspector, the architect/engineer, and contractors is recommended to discuss planned construction procedures and quality control requirements.
7. The geotechnical engineer should be notified at least 48 hours prior to beginning construction operations.

Part III – Site Preparation and System 300 -Installation PLEASE NOTE: In accordance with standard design and construction practices, The Fibar Group LLC and its Representatives recommend using the services of a certified engineer, architect, or landscape architect who is familiar with local soil and climate conditions to evaluate and interpret any information provided by The Fibar Group LLC and its Representatives. The Fibar Group LLC assumes no responsibility for determining the size of the playground or the safety zone between the equipment and the border. Installer must thoroughly examine the site and specifications, carefully checking the dimensions before starting work. All instructions are subject to equipment manufacturers’ installation specifications and in accordance with the licensing requirements of The Fibar Group, LLC, these specifications, and conformance with the dimensions, notes and details shown on the plans. In-Ground Installation (Exiting at Grade Level)
o Excavate area to proper depth, based on Critical Fall Height. o Minimum 1% downward grade to ensure proper drainage to FibarDrain Strip. o On grades of greater than 10% - use of FibarSystems is not recommended. o Remove all roots, stones, and vegetation.
o Accurately grade and firmly compact entire area, especially where fill materials have been utilized. o Excavate trench 2” wide x 6” deep, perpendicular to grade at lowest point of playground area. o Install FibarDrain and connect low end of strip to storm drain or similar device to remove collected water. o Install playground equipment.
o Install retaining border or curb.
o Install FibarDrain strips at 6’ centers in direction of grade. o Cover sub-grade and drainage trench with FibarFelt.
Allowing 3” overlap at all seams.
Slit to fit around footings of equipment.
Overlap all slits with either next piece of FibarFelt or scrap piece, to ensure complete coverage. o Permanently mark, with paint or other type of permanent marker, all the legs of the playground equipment with the compacted system design depth.
o Spread Fibar® Wood Fiber using a Bobcat, small front-end loader or our Express Blower Trucks. Care should be taken when driving over FibarDrain.
Do not make sharp turns on FibarFelt or FibarDrain.
o Install all materials delivered.
Additional materials are supplied to account for natural compaction. Feather edges to make smooth transition to grade or border. o Install FibarMat wear on top of the Fibar EWF.
o Hand-rake for a smooth & level finished surface. Natural compaction will occur over time and is dependent on the amount of playground use and environmental conditions. To accelerate the compaction process, Fibar Engineered Wood Fiber can be mechanically compacted at an additional cost. The Fibar can be compacted in the accessible route to the equipment or the entire surface area. To mechanically compact the Fibar, install in 5” lifts using a plate compactor or other
mechanical device. Change direction 90 degrees between each layer. Optional: Wet the surface before compacting. Repeat these steps until the desired level finished thickness is achieved. This accelerated compaction method, without wetting the surface, was used in the laboratory for the ASTM F1951 test procedure.
o After 2 weeks, surface should be raked and leveled. Continue to rake the surface level as needed. o Consumer Product Safety Commission (CPSC) and ASTM recommends Use Zones of at least 6 feet around all equipment, except:
Swings – Use zone equal to 2 times the height of top rail is needed in front and behind swings. Slides – Use zone equal to height of slide plus 4 feet, extending a minimum of 6 feet, in front of slide exits.
o Complete information on use zones can be found at CPSC and ASTM. Above-Ground Installation (Exiting at Border or Curb Level) o Minimum 1% downward grade to ensure proper drainage to FibarDrain Strip. FibarDrain Strip should be installed so that it discharges outside of playground borders. o On grades of greater than 10% - use of FibarSystems is not recommended. o Remove all roots, stones, and vegetation.

o Install all materials delivered.
Additional materials are supplied to account for natural compaction. Feather edges to make smooth transition to grade or border. o Install FibarMat wear on top of the Fibar EWF.
o Hand-rake for a smooth & level finished surface. Natural compaction will occur over time and is dependent on the amount of playground use and environmental conditions. To accelerate the compaction process, Fibar Engineered Wood Fiber can be mechanically compacted at an additional cost. The Fibar can be compacted in the accessible route to the equipment or the entire surface area. To mechanically compact the Fibar, install in 5” lifts using a plate compactor or other mechanical device. Change direction 90 degrees between each layer. Optional: Wet the surface before compacting. Repeat these steps until the desired level finished thickness is achieved. This accelerated compaction method, without wetting the surface, was used in the laboratory for the ASTM F1951 test procedure
o After 2 weeks, surface should be raked and leveled. Continue to rake the surface level as needed. o Consumer Product Safety Commission (CPSC) and ASTM recommends Use Zones of at least 6 feet around all equipment, except:
Swings – Use zone equal to 2 times the height of top rail is needed in front and behind swings. Slides – Use zone equal to height of slide plus 4 feet, extending a minimum of 6 feet, in front of slide exits.
o Complete information on use zones can be found at CPSC and ASTM.

For Agenda of: 2/7/2023
Placement: Consent
Estimated Time: N/A
FROM: Aaron Floyd, Utilities Director
Prepared By: Mychal Boerman, Utilities Deputy Director - Water SUBJECT: ROADMAP FOR MAXIMIZATION OF RECYCLED WATER
RECOMMENDATION
Receive and file an update related to the City’s timing and strategy for maximization of recycled water.
POLICY CONTEXT
Policies and restrictions on delivery of recycled water outside of City limits are outlined in the General Plan Land Use Element Policy 1.13.2 Recycled Water:
Provision of recycled water outside of City limits may only be considered in compliance with Water and Wastewater Element Policy A 7.3.4 and the following findings:
A. Non-potable/recycled water is necessary to support continued agricultural operations.
B. Provision of non-potable/recycled water will not be used to increase development potential of property being served.
C. Non-potable/recycled water will not be further treated to make it potable.
D. Prior to provision of non-potable/recycled water, the property to be served will record a conservation, open space, Williamson Act, or other easement instrument to maintain the area being served in agricultural and open space while recycled water is being provided.
Policy A 7.3.4, referenced above, reads as follows:
Consider the potential to deliver available recycled water supplies to customers outside the City limits, including analysis of policy issues, technical concerns, and cost recovery, provided it is found to be consistent with the General Plan.
Item 6e
DISCUSSION
Background
On November 15, 2022 the City Council held a study session to discuss opportunities for expansion of the use of recycled water in order to maximize the use of this resource. At this meeting, staff provided the City Council with long-term and short-term opportunities for maximization of recycled water. Long-term strategies included utilizing available resources to recharge the groundwater basin, either through injection wells, or percolation, and short-term strategies included expanding in-City recycled water irrigation, exchanging recycled water for a reduction in groundwater pumping by agricultural parties within the SLO Valley Subarea, and selling recycled water outside City limits during periods in which it had no feasible use within the City.
The City Council provided general feedback that staff should continue to pursue longterm use of recycled water for recharge of groundwater or surface water reservoirs and that all three short-term options should be considered in order to maximize supplies. The City Council also provided direction that staff should develop a transparent process and roadmap for recycled water sales that would be legally compliant, recover costs, and be consistent with existing City policies. Additionally, City staff were directed to coordinate with County of San Luis Obispo staff on creation and submission of a grant application that would provide the City and County Groundwater Sustainability Agencies with funding to complete elements of the Groundwater Sustainability Plan that are precursors to delivering recycled water outside of City limits. This grant application was submitted and includes a request for funding to support expansion of the groundwater monitoring network, a groundwater extraction measurement program, a pumping fee program for the Edna Valley, a supplemental water feasibility analysis, and various other activities.
Recycled Water Roadmap
Following the study session and at the direction of Council, staff began developing a Roadmap for Maximization of Recycled Water (Attachment A). This roadmap is a flowchart or process diagram which includes all short-term and long-term maximization options discussed during the study session. The roadmap details the sequential steps that that would be required prior to expanding the use of the City’s recycled water resources, specifically outlining a series of steps that are needed as part of the process to sell recycled water outside of City limits. Because parties that are interested in purchasing recycled water are attempting to understand when recycled water may be available for sale and use, the Estimated Recycled Water Delivery Timeline (Attachment B) provides projected timelines for completion of each step in the sales process, as well as additional narrative.
Previous Council or Advisory Body Action
On March 21, 2017, the City Council approved the 2017 Recycled Water Master Plan which outlined the City’s expansion strategy for recycled water use, including plans to ultimately utilize recycled water as a potable water supply in the future. On November 15, 2022, the City Council participated in a study session to provide staff with feedback regarding long-term and short-term strategies to maximize recycled water use.
Item 6e
Public Engagement
In addition to the November 2022 study session regarding recycled water maximization, staff also met with a County Supervisor, County of San Luis Obispo staff, Cal Poly staff, and the Edna Valley Growers in January 2023 regarding the availability of recycled water for short-term sales. These meetings included details related to the sales process, as well as projected timelines for delivery.
CONCURRENCE
This report has been reviewed by Utilities staff who are involved with the production and delivery of recycled water. As this project is focused within the Utilities Department, and does not impact other City departments, concurrence from other City departments is not required at this point.
ENVIRONMENTAL REVIEW
Receiving an update regarding recycled water maximization does not constitute a “Project” under State CEQA Guidelines Sec. 15378. CEQA may be required for future expansion projects and projects will be analyzed on a case-by-case basis to determine environmental review requirements.
FISCAL IMPACT
Budgeted: NA Budget Year: 2021-23
Funding Identified: NA
Fiscal Analysis:
Updates to the City Council related to recycled water maximization do not directly result in a fiscal impact. Requests for resources associated with maximization of recycled water may be brought forward as part of the 2023-25 Financial Plan. Resources required to complete maximize the City’s recycled water resources are estimated to be less than one FTE.
ALTERNATIVES
The City Council could request that staff modify projected timelines or specific work efforts associated with the Recycled Water Roadmap. Staff believe that the actions shown in the Recycled Water Roadmap and the proposed timeline are feasible for completion by staff and required to meet legal requirements associated with this project.

SUBJECT: FISCAL YEAR 2022-23 MID-YEAR BUDGET REVIEW
RECOMMENDATION
1. Receive and discuss the Mid-Year Budget report based on revised projections for all major funds at the mid-point of the 2022-23 fiscal year; and
2. Adopt a Draft Resolution entitled, “A Resolution of the Council of the City of San Luis Obispo, California, approving amendments to the adopted 2022-23 Budget Appropriations” and approve the one-time allocations as stated in the Mid-year Budget Report; and
3. Provide direction on whether the one-time budget allocations from the 2021-23 Financial Plan listed in Attachment A – Appendix B should be considered as ongoing expense and included in the base budget for 2023-25.
POLICY CONTEXT
The City’s budget policies require that the City Council review the City’s budget and financial condition at least every six months. The mid-year review is part of the ongoing quarterly reporting process and fulfills that purpose. The review allows the Council to adjust revenue and expenditure assumptions should the need arise. The accompanying Mid-Year Budget report for 2022-23 provides a comprehensive overview of the City’s financial condition half-way through the fiscal year and summarizes current financial trends since the adoption of the 2021-23 Financial Plan Supplement in June 2022.
DISCUSSION
Mid-Year Report Organization
The report’s focus is on the General Fund and each of the City’s enterprise funds. The mid-year budget report also provides an update on departmental performance measures, work programs, the Capital Improvement Plan, and Major City Goals. The report (included as Attachment A) includes the following sections:
Item 7a
Section A – General Fund Summary: This section provides a narrative overview of the City’s current General Fund financial condition and current revenue and expenditure trends as of December 31, 2022. In summary, major tax revenues are exceeding projections and have been adjusted upward accordingly. Expenditures are on track with where they should be at this point in the year; however the recent storm expenditures are not included in the mid-year financials. The revised five-year forecast is also provided and includes the estimated cost for the projected $9 million in storm expenditures and the anticipated amount and timing of reimbursement under state and federal programs.
Section B –Mid-Year Recommendations: This section outlines the proposed mid-year expenditure budget changes as well as one-time allocations of the FY 2021-22 unassigned fund balance. All of the budget changes are administrative or mission critical in nature and no new programs or services are being recommended. The recommended additional discretionary payments (ADP) to CalPERs are discussed in the next section of this Council Agenda Report and detailed in the fiscal impact section.
Section C – Enterprise Fund Summary: This section provides a narrative update of the City’s enterprise funds’ financial conditions, including any recommended budget changes.
Year-to-date expenditures and revenues are on track for all funds. Revised long-term forecasts are included.
Section D – Department Performance Measures and Work Program Updates: This section provides an evaluation on the performance measures and an update on core objectives of each operating program. All of the 74 total operating programs manage workload within budget and meet core objectives.
Section E – Capital Improvement Plan (CIP) Update: This section provides an update on active and ongoing CIP projects.
Section F – Major City Goal Update: This section provides an update on Major City Goal tasks that were either scheduled for completion in 2022-23 or are listed as “ongoing”.
Several tasks were delayed, but most were completed or are scheduled to be completed before year end.
Appendix A – Detailed Financials: This section provides a closer look at year-to-date actuals for the major funds and the recommended revenue budget adjustments.
CalPERs Additional Discretionary Payments (ADP)
With the 2018-19 Budget Adoption, Council adopted the “Fiscal Health Response Plan” to help balance the long-term forecast and begin an ambitious schedule to pay down the City’s pension obligations over 20 years instead of 30 years. This was based on the commitment to use available unassigned fund balance mainly for this purpose. In addition to the planned payment of $2 million (General Fund portion) for FY 2022-23, staff recommend allocating an additional $1.3 million of unassigned General Fund balance (due to over realized revenue) which will help offset the 6.1% investment losses that CalPERs experienced last year. For future planned payments above the regular CalPERS contributions, see the updated long-term forecasts.
Item 7a
Storm Response and Activation of the Fiscal Health Contingency Plan The City has done initial damage assessments related to the storms, but identification of the scope of the repairs needed is still in the beginning stages. Staff estimate there will be at least $2 to $3 million of operating costs associated with staff overtime, supplies, and contracted services. On top of that, Public Works continues to estimate the cost for Capital repairs which are likely to exceed $5 to $8 million. Given the magnitude of damages, the City Manager has activated the Fiscal Health Contingency Plan (Attachment C). The Fiscal Health Contingency Plan is not intended to be a specific “recipe” for expenditure cuts or revenue increases, but a framework in responding to adverse fiscal circumstances, such as natural disasters.
Since the storm related costs were unbudgeted, the City Manager requests authorization through the attached resolution to use the General Fund reserve to pay for storm-related costs through the end of the fiscal year. Given the updated revenue projections, there will likely be revenues over expenditures available at year-end to reimburse the reserve; however these revenues have not yet been realized.
Staff will continue to provide Council with storm-related updates and the broader fiscal impacts will be considered during the 2023-25 Financial Plan development. 2022-2023 One Time Expenses
As part of the development of the 2021-2023 Financial Plan, the City allocated one-time budget to fund critical services in support of Major City Goal objectives. The total amount of expenditures and the details are included as Attachment A – Appendix B. Staff has reviewed the list and reduced it to what staff believes are essential and critical items that support operations and Major City Goal objectives. Staff recommends that the Council provide direction on whether to add some or all of the costs to the ongoing budget.
Approximately $1.8 million has been assumed in the forecast for ongoing expenses related to these or other ongoing needs. Determining whether to include these specific one-time costs in the budget or whether to leave a budget “placeholder” to fund potential other needs will be useful in terms of how to weigh other competing expenditures. If Council elects to put the identified list of costs into the ongoing budget, staff will return with a budget resolution on consent at a future meeting to memorialize Council’s action.
Public Engagement
Public comment on the item can be provided to the City Council through written correspondence prior to the meeting and through public testimony at the meeting. The Mid-Year Report will also be posted on the City’s website for public review.
CONCURRENCE
The City’s internal Financial Plan Steering Committee has met on multiple occasions and concurs with the recommendations included in this report.

Mid-Year Budget Review
FISCAL YEAR 2022-23
The City’s Budget and Fiscal Policies (Financial Plan Purpose and Organization, G – Mid-Year Budget Reviews) call for a formal financial status report to the Council based on the first six months of each fiscal year. The Mid-Year Budget Review fulfills this requirement and allows the Council to take a broader look at the City’s financial picture and progress on Major City Goals or strategic initiatives shortly after the midpoint of the fiscal year.
The mid-year budget review is particularly important during a financial planning year because it gives Council a first look at the five-year fiscal forecast which will be used to help staff in developing the preliminary budget for the 2023-25 Financial Plan.
This report focuses on the current fiscal year and provides an analysis of adopted budget revenues and expenditure appropriations. It also outlines the achievements and the potential challenges for each department and the City organization as a whole and provides an update on adopted Major City Goals.
Based on the review and accompanying analysis, the City remains financially sound with most revenues tracking ahead of budget and operating program expenditures remaining within budgeted allocations.

The table below shows the updated revenue forecast for the General Fund (all revenue consolidated).
Detailed year-to-date actuals and mid-year changes by revenue type can be found in Appendix A.
Table 1 – General Fund Revenue
Sales Tax revenue remains incredibly strong through the first half of FY 2022-23, particularly in the restaurants and hotels category. The updated budget for FY 2022-23 is based on the City’s sales tax consultant, HdL’s forecasts. Growth factors reflect ongoing pandemic dynamics on sales plus inflationary pressures on the prices of goods. Based upon projections from HdL, no recession is included in the forecast. The Bradley Burns assumption includes a negative $600,000 adjustment to account for a misallocation of revenue by the California Department of Tax and Fee Administration (CDTFA) that should have been allocated to another County agency. However, this administrative adjustment is not reflective of the sales tax performance and the 4.9% increase forecasted in FY 2023-24 will return the tax revenue back to “normal” levels. The Local Revenue Measure, not impacted the administrative adjustment, is expected to see 3.9% growth in FY 2022-23. The majority of this growth coming from the “Restaurants and Hotels” and “General Consumer Goods” industry groups.
Property Tax forecasts have been increased by about $700,000 to reflect the latest forecast (September 2022) from the County Assessor’s Office. Although the housing market shows signs of cooling, it is General Fund Revenue FY 2021-22

General Fund Summary
expected that property tax will remain one of the City’s most stable revenue streams with 2-3% annual growth over the next five years.
Transient Occupancy Tax (TOT) revenue continued to hit record highs for the first half of the fiscal year; however, things are starting to level out. Based on forecasts from Visit SLO Cal, the City’s FY 2022-23 forecast has been revised upward significantly compared to the original budget. Occupancy rates are expected to stay flat however a slight dip in the Average Daily Rate (ADR) will likely result in a flattening or slight decline in TOT revenue over the next several years.
Business Tax has been adjusted upward to account for the actual revenue received this year. Business Licenses are renewed at the beginning of the fiscal year; therefore, all the revenue for FY 2022-23 has been collected.
Cannabis Tax and Operator License revenue has been adjusted downward based on delayed opening of businesses.
Gas Tax and SB1 forecasts have been adjusted based on the State’s forecast from May 2022.
Fees for Service have been marginally adjusted to account for actual year-to-date revenue or trends identified over the last six months. Specific revenue budget changes can be found in Appendix A.
Other Revenue has been adjusted downward by $1.5 million to account for a reduction in interest earnings due to the Fair Market Value (FMV) of the City’s financial assets.
Grants and Subventions are trending high because of Mutual Aid Reimbursements. This revenue helps offset expenditures and is not budgeted for.
Development Services Designation1
Based on 2021-22 audited financials and usage during the current fiscal year, the following table shows the current balance of the development services designation:

Current Balance $ 464,136
1 On June 17, 2014, the City Council revised the fiscal policies to provide for the City Manager to allocate up to 75% of Development Services over-realized revenues to acquire temporary resources for the timely processing of development applications and other permit processing activities. The policy calls for the allocated revenues to be reported to the City Council on a semi-annual basis as part of the mid-year and annual budget presentations.

General Fund Summary
Table 4: General Fund Operating Expenditures by Type
At Mid-Year, departmental budgets should typically be about 50% expended, though this can vary for departments that budget for significant non-salary expenditures that do not always follow even expenditure patterns throughout the year. Overall, the General Fund is on track with its expenditure budgets at both the department and the category level. Some notable variances include:
Non-Departmental/Support Services are cost centers for expenditures that are not department specific.
The majority of this budget includes the contingency budget for estimated wage increases based on approved Council parameters. This budget is historically kept separate because negotiations are not finalized before budget development. Based on year-to-date actuals, staff expect the entire FY 2022-23 contingency budget to be used by year end.
The Solid Waste division has significant savings due to vacant Solid Waste Manager and Coordinator positions and carryover contract services budget that has not yet been used.

General Fund Summary
Revised General Fund Long Term Forecast
The long‐term forecast is an essential planning tool for the City and its ongoing service delivery. While the City adopts a two‐year Financial Plan that must be balanced, the outer years of the forecast are presented to show the City’s financial condition and availability of resources into the future. The forecast is updated every six months which gives staff the opportunity to alert Council of looming imbalances and strategize proper actions to be taken.
Key takeaways
Overall, the General fund is in a good financial condition and stays balanced throughout the five‐year forecast at current service levels. Current assumptions are conservatively optimistic, and the forecast only assumes a cooling of the current economic activity (not a recession). The impacts of high inflation on the City’s forecast are still not entirely known.
Revenue forecasts can be very volatile but are easy to update every six months based on the latest economic data or trends. Expenditure budget forecasts are usually less volatile but only updated on an annual basis for a number of reasons: (1) not all expenditures increase at the same rate, (2) staffing costs can fluctuate based on the incumbents within the roles, and (3) CIP project budgets require significant staff time to re‐estimate. Departments will begin preparation of base budgets for the 2023‐25 Financial Plan this month; however, staff have included some assumptions for expenditures in order to provide Council with a realistic outlook.
Assumptions
1. Tax revenues have been updated as noted in the revenue section of this report and fees for service are inflated by 3% in FY 2023‐24, followed by 2% annually after that.
2. The Capital Budget allocation was increased 19% in FY 2023‐24 to account for construction cost index (CCI) increases, followed by 2% annual increases. Additionally the forecast assumes an estimated $5.2 million one‐time allocation towards the Infrastructure Investment Fund to repay potential use of funds in the current year to acquire office and future public facilities space for organizational needs. The source of this repayment is use of an unassigned balance in the debt service fund that is not needed to service debt, and projected one‐time revenues over expenditures from FY 2022‐23.
3. High level estimates for staffing from FY 2023‐24 through FY 2026‐27. These numbers will be refined with the 2023‐25 Financial Plan.
4. One‐time budget allocations have been removed with the exception of a placeholder (i.e. $1.822 million) to account for staff’s estimate of items that Council will choose to make ongoing with the 2023‐25 Financial Plan.
5. A 3% inflator included for non‐staffing budgets in FY 2023‐24, followed by 2% annually after that.
This is subject to change during base budget development.
6. The City will use part of its operating reserve in FY 2022‐23 and FY 2024‐24 to offset storm costs but will replenish it back to the 20% reserve level, consistent with policy requirements, in FY 2024‐25.
Looking Forward
The forecast is an important planning tool (i.e. it is not a budget) to consider during the 2023‐25 Financial Planning process; however, the February 11, 2023 goal setting workshop should not focus on specific numbers. Council should assume that the forecast is going to be very tight and in order to fully fund the CIP and existing operating services, there will be minimal, if any, available fund balance. Staff will take the feedback from the goal‐setting workshop and work with program managers to determine how Major City Goal work programs can be incorporated into the big picture. The preliminary budget presented in April will include the updated expenditure forecasts and outline all new budget additions or changes.

Table L1: General Fund Long Term Forecast
Long Term Forecast Footnotes:
1 – Unplanned storm response expenditures will be paid for out of the General Fund reserve with the assumption that any revenue above expenditures will be used to replenish the reserve. The forecast also assumes that 93.5% of costs will be reimbursed by FEMA (cell D21 & E21). This amount is merely an estimate. Staff will provide an update with the third quarter budget report. 2 – FY 2022-23 includes the additional discretionary payment of $1.3 M recommended in the Mid-Year Report (See cell A35).
3 – In the revised Mid-Year Column “C”, ARPA funds are removed from both the revenues and expenditures. Since the revenue was actually received in FY 2021-22, it was deposited directly into the corresponding funds as allocated by Council (R-11333). This is an administrative accounting adjustment and has no impact on the General Fund balance.

B. Mid-Year Expenditure Budget Changes
This section includes any changes to expenditure budgets, including:
1. Updated Transportation Development Act (TDA) Bikeways allocation for FY 2022-23

3. Appropriation of one-time CalPERS Additional Discretionary Payments (ADP)
4. General Fund Operating Budget Changes
5. Enterprise Fund Operating Budget Changes
1. Transportation Development Act (TDA) Article 3 Funding The State of California has designated 1/4% of the sales tax levied statewide for local transportation purposes. Funding for this program was provided during the 1971 legislative session with the enactment of the Transportation Development Act, which extended the State sales tax to include purchases of gasoline. Revenues allocated to the City of San Luis Obispo under this program are divided into two categories: Article 3 funds, which are restricted for the improvement and maintenance of street systems including pedestrian and bicycle facilities; and Article 4 funds, which are restricted for public transit systems and are recorded directly in the Transit Fund. Under the City’s Financial Plan policies, all TDA Article 3 revenues are allocated for alternative transportation purposes.
During budget development, staff include a conservative TDA revenue forecast which is then programmed towards an eligible capital project. The purpose of this adjustment is to update the revenue and expenditure budgets based on the actual 2022-23 TDA allocation.

2. SB1186 CASP Certify Funding (CASp)
The CASp fund was established by Senate Bill 1186 (2012) which requires local agencies to collect an additional fee when issuing a permit for the purpose of increasing certified access specialist (CASp) services and compliance with construction-related accessibility requirements. The first priority is to spend the funds on the training and retention of CASps in order to meet the needs of the public in the jurisdiction. The funds may also be spent on activities or programs that facilitate accessibility compliance.
The City’s Deputy Building Official is CASp certified and has been expanding the City’s CASp program. In reviewing the fund and current budget allocations, the Deputy Building Official identified that the FY 2021- 22 budget allocation was not in line with the Department of the State Architect (DSA) 2 recommendations.
These funds have not been spent and staff recommend removing them from the project budget in order to facilitate accessibility compliance programs and trainings more in line with the bill language. Some 2 The Department of the State Architect (DSA) does not advise the use of funds from the SB 1186 fee by local jurisdictions to directly fund construction projects, nor accessibility work that is not construction-related, as these activities are not clearly permissible in law (see Government Code Section 4467).

3. CalPERs Additional Discretionary Payments (ADP)
With the 2018-19 Budget Adoption, Council adopted the “Fiscal Health Response Plan” to help balance the long-term forecast and begin an ambitious schedule to pay down pension obligation over 20 years instead of 30 years. This was based on the commitment to use available unassigned fund balance mainly for this purpose. In addition to the planned payment of $2 million (General Fund portion) for FY 2022-23, staff recommend allocating an additional $1.3 million of unassigned General Fund balance (due to over realized revenue) which will help offset the 6.1% investment losses that CalPERs experienced last year.
For future planned payments above the regular CalPERS contributions, see the updated long-term forecasts.

C: Enterprise Funds
The City’s financial structure is separated into governmental funds and business activities or Enterprise funds. Business activities are distinguished from governmental funds by their similarity to private sector enterprises and are financed largely through user service charges. The City has four unique funds that fall into this category:
WATER FUND SUMMARY________________________________________________________ Revenue
Water sales are trending on track with revenue projections and revenues in prior fiscal years. At the time of writing this report, revenues only reflect four months (or 33%) of water sales because of the timing of billings. Water sales, base charges, salesto Cal Poly, and other miscellaneous utilities set up fees comprise over 90% of anticipated revenues.
Table 10: Water Fund Revenue
Typically, water consumption trends higher in the summer months, due to increased irrigation demands caused by hotter, drier weather. During the first few years of drought, water consumption usually starts high, then tapers off when the public becomes more aware of drought conditions. While water supplies are secure in the City, per-capita residential water use has decreased slightly in comparison with the first two years of the current drought (2020 and 2021) as residents and businesses have complied with the Governor’s Orders on this topic.

Enterprise Funds: Water
Graph A: Residential Gallons per Capita per Day (RGPCD) Other major sources of revenue in the Water Fund include $697,500 received through the Cal OES Hazard Mitigation Grant Program and $265,949 received through the Tetrachloroethylene Plume Characterization Planning Grant. The Water Fund has not received these funds yet because they are contingent on project timelines for the Water Treatment Plant Emergency Power (Public Safety Power Shutoff) project and the Groundwater Contamination Characterization Project.
The fund remains on track to meet revenue targets and short-term operational, capital expenditure, and reserve needs.
Operating Expenses
As projected in the Adopted Supplemental Budget 2022-23, costs related to chemicals, electricity, and capital project delivery continue to increase. Industry-specific increases have exceeded general inflation and are not anticipated to normalize this fiscal year. Chemical and electricity cost increases will continue to impact the Water Fund, as these expenses amount to more than 15% of the annual operating budget.
The City’s Water Treatment Plant and reservoirs are located in the unincorporated area and are currently not subject to Central Coast Community Energy (3CE) pricing. The recent compensation study also contributed to higher expenditures. Operating expenses are on track with appropriated budget allocations.

Additionally, deferral of rate increases has resulted in substantial reduction in revenues. Early analysis indicates that proposed rate increases in the next financial plan may exceed historic averages.
Industry-Specific Increases
Some of the most substantial increases in cost of operations were industry-specific increases in capital projects, electricity, and chemicals. For capital projects and electricity, costs have risen as much as 20%.
Chemicals are more variable and extreme, with some chemicals exceeding 100% cost increases.
Table 13: Chemical Cost Increases
Chemical 2021-22 Contract 2022-23 Contract8 % Increase
Alum $336 ton $450 ton +34%
Fluoride $1,760 ton $3,211.40 ton +82%
Chlorine (Cl2) $0.68 gal $1.40 gal +106%
Sodium Hydroxide (NaOH) $0.76 gal $1.28 gal +68%
Polymer $0.68 lb $0.95 lb +40%
Liquid Oxygen (Lox) $1.28 gal $1.30 gal +2%
For FY 2022-23, budgets have been approved contingencies that are anticipated to be sufficient to accommodate these increases. It is uncertain when these cost increases will stabilize, and it is unlikely that costs will return to historic averages.
General Inflation
Several indices corroborate what the Utilities Department is seeing reflected in the cost of operations.
The Municipal Cost Index (MCI), an index designed to reflect the effects of inflation on providing municipal services, peaked at a 12.51% annual increase in April 2022. For comparison, the year-over-year percent changes for MCI as of September for the last seven years are in the table below.

7 The initial amount was only a partial amount of the bargaining parameters and was insufficient to meet negotiated parameters.
8 One-year contract with an option to re-negotiate in 6 months due to volatile markets.
Budget Report Pg. 13
Enterprise Funds: Water
Increased Staffing Costs
The completion of the Benchmark Compensation Study resulted in more competitive salaries for City staff.
While this helps with recruitment and retention of qualified staff, it results in increased costs to provide water services. In addition to increased compensation of direct Utilities staff, the Utilities Department expects substantial increases in contributions to the Cost of Service and Cost Allocation Plan, due the expansion of internal services provided by the City. The full impact of related salary increases will be better understood once the Cost of Service and Cost Allocation Plan are completed.
Deferred Rate Increases
On June 18, 2019, Resolution No. 11023 was approved by the City Council, authorizing annual water rate increases of 5.5% , effective July 1, 2019 and July 1, 2020 respectively. The July 1, 2020 water rate increase was deferred to February 1, 2021 and reduced to 3.6% (Resolution No. 11202). The deferral and reduction of the proposed rate increases was enacted to accommodate community members who had been economically impacted by the COVID-19 pandemic.
Through four months of billings in FY 2022-23, it is estimated that revenues are $175,000 less than anticipated due to the deferred and reduced rate increase outlined in Resolution No. 11202. Cumulatively, since the deferral occurred on July 1, 2020, Water Fund revenues are estimated to be $1.58 million less than originally anticipated.

SEWER FUND SUMMARY___________ _____________________________________________ Revenue
Sewer sales are trending on track with revenue projections and revenues in prior fiscal years. At the time of writing this report, revenues only reflect three months (or 25%) of sewersales because of billing timing.
Sewer service charges, base charges, sales to Cal Poly, and other miscellaneous utilities set up fees comprise about 95% of anticipated revenues.
Table 15: Sewer Fund Revenue
Sales to Cal Poly is trending lower after inflated September 2021 billings, when Cal Poly drained a tank that resulted in 1.48 million gallons of billable outflow. Sales to Cal Poly also tends to have higher billings in the last half of the fiscal year because during the beginning of the fiscal year Cal Poly is not in session.
Other major sources of revenue in the Sewer Fund include $728,888 through the Cal OES Hazard Mitigation Grant Programs and $657,265 through the Proposition 1 Integrated Regional Water Management Implementation Grant. The Sewer Fund has not received these funds yet because they are contingent on WRRF project (SLO Water Plus) timelines.
The fund remains on track to meet revenue targets and short-term operational, capital expenditure, and reserve needs.
Operating Expenses
As projected in the Adopted Supplemental Budget 2022-23, costs related to chemicals, electricity, and capital project delivery continue to increase. Industry-specific increases have exceeded general inflation and are not anticipated to normalize this fiscal year. Chemical and electricity cost increases will continue to impact the Sewer Fund, as these expenses amount to more than 18% of the annual operating budget.
The recent compensation study also contributed to higher expenditures. Operating expenses are on track with appropriated budget allocations.

The Sewer Fund Long Term Forecast: Challenges and Considerations Industry-specific increases, general inflation, and increased staffing costs continue to impact the Sewer Fund. Additionally, deferral of rate increases has resulted in substantial reduction in revenues. Early analysis indicates that proposed rate increases in the next financial plan may exceed historic averages.
Industry-Specific Increases
Some of the most substantial increases in cost of operations were industry-specific increases in capital projects, electricity, and chemicals. For capital projects and electricity, costs have risen as much as 20%.
Chemicals are more variable and extreme, with some chemicals exceeding 100% cost increases.

General Inflation
Several indices corroborate what the Utilities Department is seeing reflected in the cost of operations.
The Municipal Cost Index (MCI), an index designed to reflect the effects of inflation on providing municipal services, peaked at a 12.51% annual increase in April 2022. For comparison, the year-over-year percent changes for MCI as of September for the last seven years are in the table below.
Table 19: Municipal Cost Index (MCI) Year-over-year
Increased Staffing Costs
The completion of the Benchmark Compensation Study resulted in more competitive salaries for City staff.
While this helps with recruitment and retention of qualified staff, it results in increased costs to provide wastewater services. In addition to increased compensation of direct Utilities staff, the Utilities Department expects substantial increases in contributions to the Cost of Service and Cost Allocation Plan, due the expansion of internal services provided by the City. The full impact of related salary increases will be better understood once the Cost of Service and Cost Allocation Plan are completed.
Deferred Rate Increases
On June 18, 2019, Resolution No. 11023 was approved by the City Council, authorizing annual sewer rate increases of 5.5% and 5%, effective July 1, 2019 and July 1, 2020 respectively. The July 1, 2020 sewer rate increase was deferred to February 1, 2021 and reduced to 3.6% (Resolution No. 11202). The deferral and reduction of the proposed rate increases was enacted to accommodate community members who had been economically impacted by the COVID-19 pandemic.
Through four months of billings in FY 2022-23, it is estimated that revenues are $93,000 less than anticipated due to the deferred and reduced rate increase through Resolution No. 11202. Cumulatively, since the deferral occurred on July 1, 2020, Sewer Fund revenues are estimated to be $950,000 less than originally anticipated.

PARKING FUND SUMMARY___________ ____________________________________ ______ Revenue
In recent years, Parking revenue has very much been in flux due to the impacts of COVID-19. However, based on revenue data for the first half of FY 2022-23, the Parking Fund is proposing no revisions to its revenue projections as part of the mid-year process. When preparing revenue estimates for the year, staff used a conservative approach considering a return to normalcy following the COVID-19 pandemic, lost parking spaces due to the parklet program, and the impacts of newer bike lanes that reduce or minimize metered parking. Staff also took into consideration rate increases and corresponding revenues, which are effective as of January 1, 2023.
Based upon available information, trends, and financial forecast, the fund is currently positioned to sustain planned operating and capital expenditures, meet reserve requirements, and cover anticipated debt payments associated with the Cultural Arts District Parking Structure. This is attributable to the adoption of additional revenue enhancement strategies and rate increases, additional enforcement staff, and strategic capital project planning. Overall, the Parking Fund has collected approximately 50 percent of projected revenues to date although there will be a dip in revenue during the holiday and spring season.
Based on revenue to date, there is no proposed revenue adjustment as part of the mid-year process.
Table 20: Parking Fund Revenue
Overall, the Parking Fund has realized approximately 56% of its projected revenues. Most revenue items are near or above the 50 percent mark, as anticipated at the mid-year point. Staff will continue to monitor revenues throughout the remainder of the fiscal year with attention to the impacts of rate increases and technology improvements such as gateless entry and exit being made available. It is important to note that some capital projects may have a short-term negative impact on parking revenues, although this revenue loss will be made up for in the long run with the improvements.
Long Term Parking – 40 percent of this revenue item has been collected, which is nearrevenue projections expected to date. This revenue is primarily based on long term parking for City and County employees, which are typically billed quarterly. This also captures downtown residents and employees who pay for monthly parking.
Other Revenue – 64 percent of this revenue item has been collected, which is consistent with revenue projections expected to date. Other revenue includes rent and lease payments, miscellaneous revenue, parking in lieu, and is primarily captured in the beginning of the given fiscal year.
Budget Report Pg. 20
Enterprise Funds: Parking
Parking Fines – 55 percent of this revenue item has been collected, which is consistent with revenue projections expected to date. An increase in enforcement efforts has led to a slight increase in citation revenue but this will likely dip over the holidays and spring seasons.
Parking Meters – 51 percent of this revenue item has been collected, which is consistent with revenue projections expected to date. Staff believes an increase in meter revenue may be realized with the implementation of credit card capable meters throughout the city – rather than coin only meters.
Parking Structures - 47 percent of this revenue item has been collected, which is consistent with revenue projections expected to date. Structure revenue has seemed to return to pre-COVID levels beginning in May 2021 when the Farmer’s Market was reestablished and non-City staff who work in the downtown area began to utilize the long-term parking program. These are positive indicators of a Parking Fund moving toward fiscal sustainability. Revenue close to expected to date.
Transfers In – This revenue item accounts for a one-time transfer of $700,000 of American Rescue Plan Act (ARPA) funds to offset revenue that would have been realized by keeping the first hour or parking free.
Operating Expenditures
The Parking Fund is trending in line with the FY 2022-23 operating budget. Throughout the fiscal year, the Parking Program has been closely monitoring operating expenses to ensure a strong fund balance to support the Cultural Arts District Parking Structure, which is actively seeking a loan in the amount of approximately $47 million. A major piece in securing this loan is meeting debt ratio requirements which considers revenues in relation to operational expenses. To date, the parking fund has been successful in carrying out core services while managing operating expenses.
Table 21: Parking Fund Operating Expenditures
Salaries and Benefits – To date, the program has expended approximately 37 percent and 31 percent of the annual budget on salaries and benefits, respectively, and will likely see salary savings across the year.
There are current vacancies in the Parking Supervisor position, as well as vacancies in the Enforcement Officer classification. Staffing shortages continue to have significant financial impacts on the Parking Fund through unrealized revenues and w a major effort is underway to build out appropriate staffing in combination with new technologies. If salary savings are realized at year end, this funding will help support the fund balance to aid long term debt obligations.

Enterprise Funds: Parking
Contract Services – The Parking Program has been conscious of spending for contract services over the first part of the fiscal year, expending 67 percent of its budget. This amount includes obligated funds that will be utilized for services throughout the remainder of the fiscal year. While still responding to deferred maintenance, repairs, and infrastructure failures, in addition to cost escalation and supply chain issues, the parking fund has balanced immediate needs while maintaining spending.
Other Operating Expenses – To date, the parking fund has expended 67 percent of its annual budget.
Again, this amount includes obligated funds that will be utilized for services throughout the remainder of the fiscal year. Last fiscal year, the program experienced excess spending in contract services primarily due to unanticipated increases in credit card merchant fees around payment transactions, print and reproduction materials for citation and parking receipts, as well as materials and supplies for day-to-day activities. The program also had to address daily impacts of transient activities in the structures including vandalism, graffiti, and debris left behind.

Enterprise Funds: Transit
TRANSIT FUND SUMMARY___________ __________________ ________________________ Revenue
The City secured grant funding from the American Rescue Plan Act (ARPA) for 100 percent of operational costs beginning in FY 2022-23 for three fiscal years that will provide emergency funding to recover from operational impacts from COVID-19. These ARPA funds will supplement driver wages and lost fare revenue. FTA 5307 funds will be used to purchase additional zero emission buses and support other capital projects. The reduction in service levels resulted in cost savings that helped to offset lost revenues.
The unused balance of annual allocations of Federal 5307 and TDA Funds have were deferred for use in FY 2022-23.
Ridership is a critical component of the on-going health of the Transit Fund. Necessary to secure State Transit Development Act (TDA) funds is a requirement that 20 percent of the programs’ operating budget be generated from local revenue – fares, bus passes, and payment for Cal Poly. During the previous fiscal year and into this year, the Transit Program has experienced a dramatic increase in ridership and fare revenue.
Staff have received updated allocation amounts from various sources and as a result, revenues have been revised as outlined below. The increase in revenue now accountsfor new, unanticipated discretionary FTA 5339 Funds that will support six (6) new buses estimated at $4.8 million. In addition, the fund is expected to realize an additional $1 million of STA funds based on updated and actual apportionments. However, there is often a delay in the posting of revenues because much funding is allocated from state and federal programs which have varied funding cycles. At this time, the Transit Fund is on tracking as expected for its annual revenues.
Table 22: Transit Fund Revenue
Operating Expenditures
The Transit Program is realizing savings in staffing as it is temporarily operating with reduced staffing levels. In addition, the program is also operating with reduced service levels due to driver shortages. This has resulted in savings in purchased transportation and maintenance. To date, the Transit Fund has expended approximately 25 percent of its operating budget and as a result, no operating budget changes are being requested. Transit will continue to monitor operations and match expenditures to revenues and take a conservative approach to managing the fund.

Long Term Forecast
There are several large pending items looming in the Transit Program’s future that could have a significant impact to the fund. Staff recently completed negotiations with Cal Poly University for a new long-term Transit Service Agreement reflective of all operational costs, which extended the agreement for a twoyear term. The Transit Program outsources its Operations & Maintenance to a third-party vendor (First Transit) and the current contract extension ends next year. The Transit fleet has six buses at the end of their useful life and the program is focused on electric bus procurement, with delivery of new buses estimated later this year. Federal funds made available via the use of Coronavirus Aid, Relief, and Economic Security (CARES) funds for operating costs were used for the purchase of two electric buses.
The cost hurdle of transitioning to an electric fleet is being addressed with federal and state funding.

Department Updates
D: Department Performance Measure and Work Program Updates Departments constantly operate in an environment of knowns and unknowns and the budget preparation considers that type of environment. Most day-to-day tasks fall into the category of known tasks with known workload associated. In addition to day-to-day activities, departments expect and budget for some level of unknown or emergent priorities. When unexpected issues arise and unknown workload emerges, divisions may experience a resource imbalance and thus slow progress on projects or strategic initiatives.
The workload assessment below took place in advance of the recent storm-related emergencies and as such those impacts are not reflected.
The COVID-19 pandemic greatly increased the number of unknowns while requiring immediate action to respond to the community’s needs. Additionally, retaining and recruiting employees has become progressively more difficult. Almost all departments are experiencing staffing challenges, illnesses and vacancies, which lead to increased workload and re-prioritization of tasks for positions that are staffed.
As part of the mid-year review, departments evaluated the core objectives of each program’s performance on the following scale:
Green indicates that the program is managing workload with the appropriated budget for current work program tasks.
Yellow indicates that a program is managing workload with the appropriated resources but may need additional resources or objective recalibration in the future to maintain long-term work programs. This could be due to higher-than-normal activity and does not necessarily indicate ongoing need. These programs will be monitored closely over the next quarter.
Red indicates that a program is not currently meeting objectives and needs either additional resources or recalibration to manage workload. This could be due to higher-than-normal activity or may indicate ongoing need. Solutions are provided for each of these programs. 83%
