Agenda packet — West Sacramento City Council, August 21, 2024 (part 2 of 7)

Tree: Any wooden perennial plant having one or several structural bearing trunk stems commonly achieving nine feet or more in height.

A tree permit is required to perform any work on a street, heritage, or landmark tree, or to trench, grade, pave or park vehicles within the dripline of these trees. Other categories of trees, such as landscaping trees on private property, are not regulated. However, for this project, as specified in the Infrastructure Project IS/MND, the City tree administrator determined that, because of the significance of trees as a key element of the neighborhood’s identity, the requirement under the City’s Tree Preservation Ordinance to replace only heritage, native, and landmark trees and street trees would be expanded to include all trees that require removal.

The Infrastructure IS/MND specifies that trees will be evaluated on a case-by-case basis where construction activities are identified as affecting roots or branches. The City will make every reasonable effort to preserve trees where feasible; however, where tree removal cannot be avoided, replacement trees will be made available to homeowners through the City Parks and Recreation Department’s West Sacramento Tree Program.

MM BIO-3a Minimize Potential Impacts on Trees and MM BIO-3b Implement Mitigation for Removed Trees of the Infrastructure IS/MND minimize potential impacts on trees.

Methods
ESA’s International Society of Arboriculture (ISA) Certified Arborist, Jessica Orsolini (ISA No. WE-7845A; Tree Risk Assessment Qualified), with assistance from biologist Berlin Hernandez, collected field data on December 26th and 29th, 2023. The project design was revised in February 2024 so additional fieldwork was conducted on March 13th, 14th, and 18th, 2024. The trees surveyed for this arborist report include any tree in or overhanging the proposed work area with a minimum 2” diameter at breast height (DBH). The location of each tree was recorded using Geographic Positioning System (GPS) technology. Each tree surveyed was assigned a unique number, though no tagging was conducted. Tree tables are provided in Attachments B and C.

In December 2018, an arborist from West Coast Arborists, Inc. conducted a tree survey which included a portion of the project site. Where those trees overlapped the survey area, ESA updated the relevant information and assessed potential impacts. Numbering of the previously surveyed trees was left the same as the 2018 survey numbering for consistency, though an “E” representing “existing” was added to each number to identify them as the previously surveyed trees and to avoid numbering duplication with the newly surveyed trees. Data for previously surveyed trees is presented in Attachment B, while data for trees not previously surveyed is presented in Attachment C.

The DBH of publicly accessible trees was measured at approximately four and one-half feet above the ground; the DBH of private trees was estimated. The height and dripline of each tree was estimated. Tree condition was judged with respect to structure, vigor, defects, conformance to generally accepted arboricultural standards of care, disease, and danger of falling. Each tree was assigned to one of six categories for tree condition. The six categories were good (G; no defects or minor defects), fair to good (F-G; defects), fair (F; more serious defects), fair to poor (F-P; severe or compounding defects), and poor (P; severe or compounding defects, and short-term death or structural failure of the tree is expected). Condition was judged based on an external inspection of each tree from the ground.

In addition to collection of the basic tree data and the condition assessment, the distance from the edge of each tree trunk to the edge of the proposed work area was recorded to assess the potential for root impacts. Notes were made regarding the potential for tree trimming or removal based on the distance of the tree to the work area and the height of overhanging branches.

Results
Tree locations are shown on the figure in Attachment A and tree data is presented in Attachments B and C. A total of 355 trees were surveyed and assessed for potential construction impacts. This includes 306 newly surveyed trees and updates to 49 trees previously mapped by West Coast Arborists, Inc. (ten trees previously mapped by West Coast Arborists, Inc. in the survey area have been removed, no longer exist, or were recorded as the wrong species and are not counted in the tree total). Due to the project design change in February 2024, 51 trees mapped during the December surveys no longer occur adjacent to proposed work. These trees are still shown on the figure in Attachment A and in the tree tables in Attachments B and C but are shown on the figure with no impacts and noted in the table that the project was redesigned and therefore won’t be impacted.

Of the 355 trees surveyed, 99 are considered heritage trees under the West Sacramento tree ordinance due to their size. A total of 18 trees surveyed were in good condition, 105 were in fair-good condition, 173 were in fair condition, 42 were in fair-poor condition, and 17 were in poor condition. Data collected for each tree is shown in the tables in Attachments B and C.

The assessment of canopy pruning was based on tree condition at the time of the survey. Due to the winter timing of the survey, most of the deciduous trees were without leaves. Additionally, spring growth is expected between the survey and project initiation. Consequently, the assessment of canopy pruning is an estimate and may vary at the time of construction. Based on the height and length of branches overhanging the work areas at the time of the survey, 22 trees are likely to need canopy pruning to provide equipment access and an additional 94 may need pruning depending on the height of the equipment, amount of spring branch growth, and how much the branches are weighed down after they leaf out. Two-hundred and thirty-nine (239) trees had sufficient clearance at the time of the survey that canopy pruning is not anticipated, or they are now located outside the proposed project work area.

Tree roots are typically shallow, spread wide, and horizontally oriented. The portion of the root zone that is essential for tree health and stability is called the critical root zone. The critical root zone varies depending on the species, age, and site conditions around the tree, though a common rule of thumb is to use the dripline to estimate the outer edge of the critical root zone (PNISA, 2022). For the purposes of the analysis in this report, the critical root zone was considered at the edge of the estimated dripline. All but five trees surveyed adjacent to proposed work will likely have some work occurring within the critical root zone. Of the trees with critical root zones occurring outside the work area, three are small, recently planted gingko trees and two are small recently planted crape myrtle trees that have a critical root zone that likely occurs at the very edge of the work area.

Within the critical root zone are the structural roots that help anchor the tree. Structural roots may be estimated at a distance approximately equal to the circumference at breast height measured horizontally from the trunk (Costello and Jones 2003). To determine the area of predicted structural roots around each tree, the circumference of each tree was first calculated based on the DBH measurement. For trees with multiple trunks, the DBH was calculated by taking the square root of the sum of all squared trunk stem DBHs to reach a single DBH that more 200

accurately represents the basal area and thus the estimated structural root area. Using circumference of each surveyed tree, the structural root zone of each tree was calculated and compared to the distance to the proposed work. The structural root zone of each tree was determined to either be outside, inside, or at the edge (within 6 inches) of the proposed work areas. Due to the variability of root systems and variability of construction impacts, trees identified at the edge may or may not have structural roots in the work zone.

The structural root zone of a total of 115 trees occurs within the proposed work area, and a total of 50 trees have a structural root zone that approaches the edge of the proposed work area. The structural root zone of the remaining 190 trees occurs outside the proposed work area. Trees with structural root zones in the proposed work area are labeled on the figure in Attachment A.

The condition of each tree with a structural root zone in or at the edge of the proposed work area was reviewed to further assess potential construction impacts. Trees in fair-poor or poor condition may have a lower likelihood of survival or recovery if structural roots are cut. There are 28 trees in fair-poor condition and nine trees in poor condition with structural root zones occurring in the work area; one additional tree in poor condition and three additional trees in fair-poor condition have structural root zones occurring at the edge of the work area. Of these, 21 are heritage trees (see the tree tables in Attachments B and C).

During the survey, the roots of 26 trees were noted to be lifting or cracking the curb, road, or sidewalk or growing over the curb adjacent to the proposed curb improvement. These trees are: tree 1E – a coast redwood; tree 5E – an English walnut; trees 6E, 53E, and 126 – white mulberries; tree 10E – a Monterey cypress; trees 11E and 263 – silver maples; tree 13E – a deodar cedar; trees 14E, 19E, 25E, 31E, 32E, 33E, 40E, 108, and 160 – London planes; tree 23E a valley oak; tree 26E – a Modesto ash; tree 36E – a silver dollar gum; tree 97 – a Chinese tallow; tree 182 – an ash, tree 197 – a saucer magnolia, and tree 284 – a gingko. The roots of tree 42E, a London plane tree, are growing over the curb.

In addition to trees observed damaging the curb, gutter, road, and sidewalks, another 15 trees were also noted to have roots visible at the curb adjacent to the proposed work area. These trees consist of: tree 8E – a littleleaf linden, tree 20E – a Siberian elm, trees 28E, 211, 212 – a London plane, tree 37E – an American sweetgum, tree 117 – a valley oak, tree 183 – an ash, tree 188 – a silver maple, tree 207 – an eastern redbud, tree 208 – an English walnut, tree 209 – an edible fig, tree 250 – a flowering plum, tree 258 – a Canary Island date palm, and tree 285 – a gingko.

Discussion
Tree roots provide multiple functions, including anchoring the tree and supplying the crown with water and mineral nutrients. Protection of tree roots is one of the most critical aspects of tree preservation during construction. Most tree roots grow within 3 feet of the soil surface and most fine roots (short-lived roots that absorb water and mineral nutrients) are within the top 12 to 18 inches of the soil surface. While the critical root zone is often considered to extend to the edge of a tree’s dripline, tree roots can extend far beyond the dripline and occupy two to ten times the area beneath the canopy. Root growth is highly opportunistic, creating asymmetric forms. They proliferate in areas favorable for their growth, where water, nutrients, and oxygen are abundant (Matheny and Clark, 1998). Tree stability depends on both the root system architecture and the anchorage of roots in the soil. The larger the root plate, the greater the force needed to tip a tree. Uneven 201

distribution of roots and large sections without roots reduces anchorage. Similarly, development of lateral roots increase anchorage of trees subject to wind loading (Watson et al., 2014).

Most of the trees surveyed were likely planted after construction of the sidewalks and roads. Roads, sidewalks, and other surfaces often restrict root extension due to compacted soils. Some studies indicate that roots generally don’t extend very far under intact pavement, and sometimes taper off in as little as 4 inches (Day and Wiseman, 2009). While soil under pavement can be difficult for root growth, there are exceptions. For example, some trees can elongate roots through compacted soil when it is softened by moisture and coarse textured soils are less compactable than fine textured clays so roots may penetrate more deeply in these soil types (Day and Wiseman, 2009). Roots often grow in the gap between the pavement and the compacted soil under it. The likelihood of roots in these areas increases with the size, age, and growth rate of the tree, and distance between the tree and area of pavement. Large trees in restricted planting spaces are most commonly associated with pavement damage (Watson et al., 2014).

Work will occur within the critical root zone of nearly all the trees adjacent to the proposed work and within the structural root zone of 115 to 165 trees. Due to the variability of root growth and the anticipated reduction of root growth under the road and sidewalk, it is difficult to predict with certainty the number of roots that may be lost due to construction. Trees that are currently visibly impacting the curb, gutter, and road, or with visible roots adjacent to the work area (listed above) have an increased likelihood of root impact/loss due to excavation required for construction. The amount of root removal a tree can tolerate is dependent on the species and health of the tree. It is commonly thought that a healthy, vigorous tree can tolerate removal of approximately one-third of its roots, and potentially up to 50 percent, although there may be stability problems if all the roots on one side are severed. Old trees and those of low vigor are less tolerant of root impacts. Due to the variability of rooting patterns, it is also difficult to know at what point 30 to 50 percent of the roots have been impacted (Matheny and Clark, 1998).

While canopy pruning for clearance may be needed on up to half of the trees, nearly all branches that may need pruning were small in diameter. The overall foliage and branch removal anticipated to be needed is insubstantial compared with the entire canopies. Impact from canopy pruning is expected to be low.

Recommendations
Roots greater than 4 inches in diameter are usually structural roots. Removal of structural roots may greatly reduce the anchorage of the tree and increase the probability of the tree falling over. Work within the structural root zone should be avoided to the maximum extent possible. Where avoidance is not possible, damage to tree roots should be minimized.

Excavation of soil in the root zone at the limit of construction activities will help determine the extent of root impacts. In many cases roots may grow up to, and parallel immediately behind the existing gutter. The least impactful replacement method may be to 1) remove the existing curb/gutter, 2) expose adjacent roots using hand tools, and 3) build the forms for the new curb/gutter only up to the existing roots (i.e., the back of the existing gutter) without severing any roots. Accomplishing this may require flexibility in construction methods and design.

The following 39 trees are heritage trees in fair or better condition that will have work occurring in the structural root zone: tree numbers 78, 102, and 117 (valley oaks); 1E (coast redwood); 2E, 3E, 7E, 14E, 19E, 21E, 22E, 202

Consideration for construction redesign to avoid impacts in the critical root zone should be given to further preserve these heritage trees currently in fair or better condition.

The following recommendations will help protect trees during construction. These recommendations should be added to the design drawings or bid specifications to ensure implementation and protection of trees during construction.
• The canopy of retained trees that overhang the work area should be pruned to the minimum height required for construction. Pruning should be conducted by an ISA certified tree worker or arborist in accordance with American National Standard Institute (ANSI) A300 Pruning Standard or adhere to the most recent edition of ANSI Z133.1.
• Areas within the critical root zone of retained trees which will not be directly impacted by construction should be avoided. No driving, parking, or storage of equipment or materials should occur within avoided areas of the critical root zone. Entry of construction personnel into the avoidance area should not be allowed except for activities undertaken for the protection of the tree. • Roots should be uncovered using hand tools, air spades, or water spades. After the roots are uncovered, root pruning should be conducted along the limit of work. Roots should be pruned to the same depth, and no more, as adjacent excavation. Roots should be pruned by a method that cuts them cleanly such as a rock saw, vibrating knife, narrow trencher with sharp blades, or hand excavation and sawing. Roots should not be severed with backhoes, excavators, bulldozers, graders, or other rough grading equipment that may pull or shatter tree roots. Where possible, roots may be shaved flat rather than cut. This can be done using a chainsaw or debarking tool.
• Exposed roots should be kept moist to minimize water loss, and the soil should be replaced as quickly as possible. The purpose of root pruning is to remove only those roots that need to be removed to complete construction, without further damaging the root system. • If during project implementation, a root greater than 4 inches diameter is encountered that needs to be cut, the tree should be further evaluated by a certified arborist to determine if the tree should be removed all together to eliminate a falling hazard.

subject Bat Habitat Assessment Results for the State Streets Pavement Rehabilitation Project On behalf of the City of West Sacramento, two Environmental Science Associates (ESA) qualified biologists conducted a habitat assessment for roosting bats at the State Streets Pavement Rehabilitation Project (Project) located in the City of West Sacramento, Yolo County, California. The Project is part of the larger City of West Sacramento States Streets Infrastructure Project (Infrastructure Project) which has been largely completed. The Infrastructure Project included replacement of approximately 9,600 feet of water main and rehabilitation of approximately 36,000 feet of sewer main. The State Streets Pavement Rehabilitation Project will repair and/or remove and replace curbs and gutters and install curb ramps that comply with the Americans with Disabilities Act (ADA) within the State Streets neighborhood. The purpose of the habitat assessment was to comply with Mitigation Measure (MM) BIO-2b of the State Streets Infrastructure Initial Study/Mitigated Negative Declaration (IS/MND) and Mitigation Monitoring and Reporting Plan (MMRP) (Horizon Water and Environment, 2019).

MM BIO-2b requires completion of a daytime bat habitat suitability assessment to determine if any of the trees in the project area that may be removed, trimmed, or pruned contain potential colonial bat roosting or indications of bat use. As required by MM BIO-2b, the habitat suitability assessment was conducted prior to the removal or pruning of trees within the project site. As described in this memo, four trees in or adjacent to the project site were determined to provide potentially suitable bat roosting habitat; only two of those trees may be impacted by construction. No bats or active roosts were observed.
228
Bat Habitat Assessment Results for the State Streets Pavement Rehabilitation Project 2 Location
The project is located in the State Streets residential neighborhood of the City of West Sacramento, Yolo County, and is bounded by Jefferson Boulevard to the east, Park Boulevard to the west, 15th Street to the north, and Stone Boulevard to the south. All pavement rehabilitation work will occur on City property along the sidewalk, curb, gutter, and road. Some pruning of private trees on adjacent parcels may be required.

Methods
ESA biologists, Berlin Hernandez and Jessica Orsolini, conducted the daytime habitat assessment for bats on December 26th and 29th, 2023, and March 13th, 14th, and 18th, 2024. An arborist survey was conducted concurrently to determine the potential for tree pruning and removal. The surveys included an inspection of all trees with a minimum 2” diameter at breast height (DBH) within or immediately adjacent to the project footprint.

The survey was completed outside of the bat maternity season, which is typically May 1st to August 31st, depending on bat species. In accordance with MM BIO-2b, trees proposed for removal or pruning in the survey area were inspected for roosting bats, their sign (e.g. guano, staining, smells, or sounds), and suitable habitat (e.g. large tree cavities, basal hollows, loose or peeling bark, larger snags, and palm trees with intact thatch). Trees rooted outside the project footprint, but within approximately 10 feet of proposed work were also assessed due to the potential for noise and vibration or root pruning activities to disturb roosting bats. Trees in the survey area were examined at close range and from a distance using binoculars for the presence of bats, bat sign, or habitat suitable for roosting. As required by MM BIO-2b, each tree was rated on a scale of 1 to 3 (1 = unsuitable/low suitability; 2 = potentially suitable, and 3 = identifiable roost). The location of all trees in the survey area were recorded using Geographic Positioning System (GPS) technology and the rating and bat habitat notes of each tree were recorded in an ArcGIS Field Maps application.

Results
A total of 347 trees in the survey area were examined by the biologists for signs of bat occupancy, bat sign, and suitable bat habitat. No bats, bat sign, or active bat roosts were observed in any of the trees. Four trees were rated 2 due to the presence of potentially suitable bat habitat. Trees with potentially suitable bat habitat are shown in Figure 1 and described below.

Tree 1, a zelkova (Zelkova serrata), was rated 2 due to a substantial number of deep cavities that could provide suitable habitat. This zelkova is an older tree in fair to poor condition with a DBH of 35 inches and a height of approximately 50 feet. After completion of the survey, the project was redesigned to avoid this tree. No construction impacts are anticipated.

Tree 10, a Mexican fan palm (Washingtonia robusta), was rated 2 due to the presence of intact thatch that could provide suitable habitat for a bat roost. This Mexican fan palm is a two-trunked tree in good to fair condition with DBH’s of 22.5 and 21.5 and a height of 50 feet. After completion of the survey, the project was redesigned to avoid this tree. No construction impacts are anticipated.

Tree 256, a Canary Island date palm (Phoenix canariensis), was rated 2 due to the presence of substantial intact thatch that could provide suitable habitat for a bat roost. This Canary Island date palm is in good to fair condition with a DBH of 26 inches and height of 50 feet. Photo 1 below shows the Canary Island date palm. 229
Bat Habitat Assessment Results for the State Streets Pavement Rehabilitation Project 3 Tree 258, a Canary Island date palm (Phoenix canariensis), was rated 2 due to the presence of substantial intact thatch that could provide suitable habitat for a bat roost. This Canary Island date palm is in good to fair condition with a DBH of 29.5 inches and height of 60 feet. Photo 2 below shows the Canary Island date palm.

Data recorded for the trees with potential bat roosting habitat can be found in Table 1. Most of the other trees surveyed were rated 1 due to a lack of snags, cavities, and peeling bark. Several trees rated 1 during the survey did contain cavities; however, due to a lack of depth, and/or poor angle of approach, and/or short distance of the cavity to the ground, these trees were not considered suitable bat roosting habitat. None of these trees had indications of bat use such as guano or staining. Additionally, the entire project area is in a high-density residential neighborhood with limited foraging habitat and frequent disturbance reducing the suitability of the entire area as bat habitat.

Discussion and Recommendations
The surveys conducted on December 26th and 29th, 2023, and March 14th, 15th, and 18th, 2024, satisfy the requirements of MM BIO-2b to conduct a habitat assessment and survey for roosting bats in any trees that are to 230
Bat Habitat Assessment Results for the State Streets Pavement Rehabilitation Project 4 be removed, trimmed, or pruned as part of the Project. Trees rated 1 require no additional measures. Trees rated 2 which will be removed, trimmed, or pruned require completion of an evening emergence survey to determine occupancy status.

Within the survey area, trees 256 and 258, Canary Island date palms, were both rated 2. The trees are about 10 feet apart and are within approximately 4 feet from the proposed curb and gutter improvements. Due to the height of the canopy of these trees, they likely won’t require canopy pruning for construction access. The trees’ roots, however, will likely be impacted by construction of the new curb and gutter. Construction work that directly impacts a tree’s roots or trunk or causes indirect impacts through noise and vibration could result in disturbance of a bat roost if present. Trees 1 and 10, a zelkova and Mexican fan palm, were rated 2 but will not be removed, trimmed, or pruned for construction due to a project redesign.

As required by MM BIO-2b, if construction work will impact the Canary Island date palms that were rated 2, a survey will need to be conducted for bats for a minimum of 2 nights during the maternity season (May 1st to August 31st) using acoustic monitoring and night-vision technology to assess bat use and roosting patterns. If bat roosts are found in any of the trees during the evening surveys, MM BIO-2b requires their rating to be changed to 3 and subsequent implementation of MM BIO-2c to avoid and minimize impacts on bats and bat roosts.

ESA biologists are available to coordinate with Bennett Engineering Services to develop a survey methodology for the City of West Sacramento and the California Department of Fish and Wildlife (CDFW) to review and approve prior to conducting the evening surveys. We appreciate the opportunity to provide services for the City of West Sacramento State Streets Pavement Rehabilitation Project. Please contact me with any questions.

Sincerely,
Berlin Hernandez

SECTION 2

SCOPE OF WORK

2.01. INTENT OF CONTRACT DOCUMENTS
The intent of the Contract Documents is to prescribe the details for the construction and completion of the Work, which the Contractor undertakes to perform in accordance with the terms of the Contract. These General Conditions are meant to replace Division I of the State Standard Specifications for all City public works contracts which incorporate these General Conditions by reference.

Where the Specifications and Plans describe portions of the Work in general terms, but not in complete detail, it is understood that only the best general practice is to prevail and that only materials and workmanship of the first quality are to be used. Unless otherwise specified, the Contractor shall furnish all labor, materials, tools, equipment and incidentals and do all the Work involved in performing the Contract in a satisfactory and workmanlike manner.

The technical provisions are presented in sections for convenience. However, this presentation does not necessarily delineate trades or limits of responsibility. All sections of the Specifications and Plans are interdependent and applicable to the Project as a whole.

The Contract Documents are complementary, and what is called for in any one shall be as binding as if called for in all. Anything shown on the Drawings and not mentioned in the Specifications or mentioned in the Specifications and not shown on the Drawings shall have the same effect as if shown or mentioned respectively in both. Any work shown on one Drawing shall be construed to be shown in all Drawings and the Contractor will coordinate the Work and the Drawings.

If any portion of the Contract Documents shall be in conflict with any other portion, the various documents comprising the Contract Documents shall govern in the following order of precedence: Change Orders; Addenda; Shop Drawings, Drawings, Supplementary and Special Conditions; Designation of Subcontractors; Construction Contract; General Conditions; City of West Sacramento Standard Specifications; State of California Department of Transportation (Caltrans) Standard Specifications 2015.

Detail Drawings take precedence over General Drawings. As between schedules and other information given on Drawings, the Schedules shall govern. If an item is shown on any Drawing and not specifically included in Technical Specifications specific to this project, the Drawing shall govern. Any conflict or inconsistency between or in the drawings shall be submitted to the Engineer for clarification as soon as the Contractor becomes aware of such inconsistency.

2.02. CONTRACTOR’S UNDERSTANDING
It is understood and agreed that the Contractor has, by careful examination, satisfied itself as to the nature and location of the Work, the conformation of the ground, the character, quality and quantity of the materials to be encountered, the character of equipment and facilities needed preliminary to and during the prosecution of the Work, the general and local conditions, and all other matters which can in any way affect the Work under this Contract. No verbal agreement or conversation with any officer, agent or employee of the City, either before or after the execution of this Contract, shall affect or modify any of the terms or obligations contained herein.

2.03. CHANGES IN THE WORK
(a) The City may, at any time, by written order, make changes in the Work as deemed necessary by the Engineer. Such changes include, but are not limited to:
(1) In the Specifications or Plans;
(2) In the sequence, method or manner of performance of the Work; (3) In the owner-furnished facilities, equipment, materials, services or site; and (4) Directing acceleration of the Work.
(b) If such changes cause an increase or decrease in the Contractor’s cost of, or time required for, performance of the Contract, an equitable adjustment will be made and the Contract modified in writing accordingly.
(1) Change Orders
A change pursuant to this section will be in the form of a Change Order, which will set forth the work to be done or the method by which the change and cost adjustment, if any, will be determined, and the time of completion of the work.

Upon receipt of a Change Order, the Contractor shall proceed with the ordered work. If ordered in writing by the Engineer, the Contractor shall proceed with the work so ordered prior to actual receipt of a Change Order. A Change Order executed by the Contractor and approved by the Engineer is an executed Change Order as that term is used throughout this section.
(2) Change Order Protests
A Change Order may be issued to the Contractor at any time. Should the Contractor disagree with any terms or conditions set forth in a Change Order, which he has not executed, he shall submit a written protest to the Engineer within fifteen (15) days after the receipt of such Change Order. The protest shall state the points of disagreement and, if possible, the quantities and cost involved.

If a written protest is not submitted, payment will be made as set forth in the Change Order. Such payment shall constitute full compensation for all work included therein or required thereby. Such unprotested Change Orders shall be considered as executed Change Orders.

Where the protest concerning a Change Order relates to compensation, the compensation payable for all work specified or required by said Change Order to which such protest relates will be determined in the same manner as provided in Section 2.04 of this section. The Contractor shall keep full and complete records of the cost of such work and shall permit the Engineer to have such access thereto as may be necessary to assist in the determination of the compensation payable for such work. Where the protest concerning a Change Order relates to the adjustment of time and for completion of the Work, the time to be allowed therefor will be determined as provided in this section.

The consent of the Contractor’s sureties shall not be required as to any change or Extra Work, and the liability of the Contractor’s Bonds shall be increased or decreased accordingly without notice to the sureties.

2.04. PROCEDURES AND ALLOWABLE COSTS ON CHANGES AND ADDITIONS TO WORK
(a) Forms of Payment
If the change in, or addition to, the Work will result in an increase in the contract sum, the City shall have the right to require the performance thereof. The compensation to be paid for any such work shall, in the City’s sole discretion, be determined in one or more of the following ways:
(1) By extension of agreed unit prices, if unit prices are required by the City’s Bid form and provided with Contractor ‘s bid;
(2) By revision of unit prices;
(3) By proposal and Acceptance of an agreed upon lump sum; and (4) On a force account basis.

Until one of the above methods is agreed on, or if the Work is to be paid for on a time and materials basis, the Contractor shall keep full and complete records of the cost of such work in the form and manner prescribed by the Engineer and shall permit the Engineer to have access to such records as may be necessary to assist in the determination of the compensation payable for such work.
(b) Lump Sum Payment
The City, in its sole and absolute discretion, may request a lump sum proposal by Contractor to perform the change in, or addition to, the Work performed. Such lump sum proposal shall be submitted by the Contractor within ten (10) days of the City’s request therefor.

Request for a lump sum proposal by City shall not be deemed an election by City to have the Work performed on a lump sum basis. Costs of preparing the proposal shall not be compensable.
(1) Contents of Lump Sum Proposal
(2) The Contractor’s proposal shall be itemized and segregated by labor and materials for the various components of the change (no aggregate labor total will be acceptable). The proposal shall be accompanied by signed proposals of any Subcontractors, which will perform any portion of the change, and of any persons who will furnish materials or equipment for incorporation therein. The proposal shall also include the Contractor’s estimate of the time required to perform said changes or additional work. (3) Computation of Labor Costs
The portion of the proposal relating to labor, whether by the Contractor’s forces or the forces of any of its Subcontractors, may include the projected wages of the reasonably anticipated Site labor, including foremen, who will be directly involved in the change in the Work.

These projected wages shall not include charges for assistant superintendents, superintendents, office personnel, timekeepers and maintenance mechanics.

Labor costs may also include Contractor’s overhead and profit which shall be computed by adding to the labor costs either up to fifteen percent (15%) of the projected wages, but not payroll costs, or the labor surcharge set forth in the California Department of 277
George Reed, Inc.

CPC24-209 State Streets Pavement Rehabilitation
142 Working Days
Updated 2/17/23
Transportation publication entitled Labor Surcharge And Equipment Rental Rates, which is in effect on the date upon which the Work is accomplished and which is a part of the Contract. The method of computing the overhead and profit shall be solely within the discretion of the City.

The labor surcharge, if used, shall constitute full compensation for all payments imposed by State and Federal laws and for all other payments made to, or on behalf of, the workmen, other than actual wages as defined above. No time or charges will be allowed except when the workers are actually engaged in the proper, efficient and diligent performance or completion of the extra work as authorized. Overtime shall not be worked without prior approval of the Engineer.
(4) Computation of Equipment and Materials Costs
The portion of the proposal relating to materials may include the reasonably anticipated direct costs to the Contractor or to any of its Subcontractors of materials to be purchased for incorporation in the change in the Work. This portion of the proposal may also include transportation and applicable sales or use taxes. Up to fifteen percent (15%) of these direct costs may be included as overhead and profit for the Contractor or any such Subcontractor (such overhead and profit to include all small tools).

This portion of the proposal may further include the Contractor’s and any of its Subcontractors’ reasonably anticipated costs for the rental and operation of prime construction and automotive equipment furnished and used in connection with the change in the Work. The equipment rental and operation rates used shall be the latest edition of the Department of Transportation, Division of Construction, Equipment Rental Rates. These costs shall not include charges for listed equipment or major tools with a new cost of five hundred dollars ($500.00) or less. No time charges shall be allowed except for equipment actually used for the proper and efficient performance or completion of the authorized change in the Work. (5) Subcontractors
The lump sum proposal may include up to five percent (5%) of the amount, which the Contractor will pay to any of its Subcontractors for the change in the Work as allowable overhead and profit to the Contractor.
(6) Failure to Submit Lump Sum Proposal
In the event that the Contractor fails to submit its proposal within the designated period, the Engineer may direct the Contractor to proceed with the change or addition to the Work and the Contractor shall so proceed. The Engineer shall unilaterally determine the reasonable costs and time to perform the work in question, which determination shall be final and binding upon the Contractor.
(7) Failure to Agree on Lump Sum Amount
In the event that the parties are unable to agree as to the reasonable costs and time to perform the change in or addition to the Work based upon the Contractor’s proposal and the Engineer and City do not elect to have the change in the Work performed on a time and material basis, the Engineer and City shall make a unilateral determination of the reasonable cost and time to perform the change in the Work, based upon their own estimates, the Contractor’s submission or combination thereof. In such instances, a Change Order shall be issued for the amount of costs and time determined by the Engineer and the City and shall become binding upon the Contractor unless the Contractor submits its protest in writing to the 278
George Reed, Inc.

Updated 2/17/23
City within thirty (30) days of the issuance of the Change Order. The City has the right to direct the Contractor in writing to perform the change in the Work, which is the subject of the Change Order. Failure of the parties to reach agreement regarding the costs and time of performing the change in the Work and/or any pending protest shall not relieve the Contractor from performing the change in the Work promptly and expeditiously.
(c) Payment by Unit Prices
If any of the items included in the lump sum proposal are covered by unit prices contained in the contract document, the City may, if it requires the change in the Work to be performed on a lump sum basis, elect to use these unit prices in lieu of the similar items included in the lump sum proposal in which event an appropriate deduction will be made in the lump sum amount prior to the application of any allowed overhead and profit percentages. No overhead and profit shall be applied to any unit prices. (d) Payment on a Force Account Basis
If the City elects to have the change or addition to the Work performed on a force account basis, the Work shall be performed, whether by the Contractor’s forces or the forces of any of its Subcontractors or Sub-Subcontractors, and payment shall be made subject to the following provision. The Contractor will be paid the direct costs of the labor, equipment and materials used in performing the force account work determined as hereinafter provided. (1) For labor, the Contractor will be paid the cost of labor for the workers (including foremen when authorized by the Engineer or Project Manager) used in the actual and direct performance of the work. The cost of labor, whether the employer is the Contractor or any or any Subcontractor of any tier, shall be actual wages, including basic hourly wage, health and welfare payments and pension payments incurred in performing the force account work, plus any travel and subsistence payments for the workers performing such work and made necessary thereby. To the actual wages shall be added a labor surcharge as set forth in the State Department of Transportation publication entitled “Labor Surcharge and Equipment Rental Rates”, as in effect on the date the work is performed. The labor surcharge shall be deemed to encompass the City’s entire liability to reimburse the Contractor for workers compensation insurance payments, social security payments, Medicare payments, federal unemployment insurance payments, state unemployment insurance payments and state training taxes, made necessary by the force account work.
(2) For equipment, the Contractor will be paid for the use of equipment at the rental rates listed for that equipment in the State Department of Transportation publication entitled “Labor Surcharge and Equipment Rental Rates”, which is in effect on the date the work is performed, regardless of ownership or any rental agreement entered into by Contractor for such equipment. The rental rate paid in accord with said publication shall be deemed to include the cost of fuel, oil, lubrication, supplies, small tools, attachments, repairs and maintenance, depreciation, storage and insurance for said equipment. Rental time will not be paid when equipment is inoperable due to breakdowns, repairs or maintenance. Payment for loading, transporting and unloading time will be in accordance with the State Standard Specifications applicable to loading, transporting and unloading equipment for force account work, as applicable as of the date the equipment is loaded, transported or unloaded. (3) For materials used in the work, the City will pay for materials furnished by the Contractor and necessarily used in the force account work. Prior to markups as set forth below, the amount paid shall be the price paid by the actual purchaser to the actual supplier plus any necessary actual costs of handling the materials. 279

Contractor may add fifteen percent (15%) to the total labor, equipment and material charges as the total overhead and profit to the entity or entities actually performing the force account work. If the entity or entities actually performing the work are Subcontractors or Sub-Subcontractors, the Contractor shall be allowed five percent (5%) of the total charge of the performing entity or entities (including mark- up) as Contractor’s mark-up. No other mark-ups shall be allowed hereunder.

The Contractor shall submit to the City daily work and material tickets, to include the identification number assigned to the change in the Work, the location and description of the change in the Work, the classification of labor employed (and names and social security numbers), hours expended, the material used, the equipment rented (not tools) and such other evidence of cost as the City may require. The City may require authentication of all time and material tickets and invoices by persons designated by the City for such purpose. The failure of the Contractor to secure any required authentication shall, if the City elects to treat it as such, constitute a waiver by the Contractor of any claim for the cost of that portion of the Change in the Work covered by a non-authenticated ticket or invoice; provided, however, that the authentication of any such ticket or invoice by the City shall not constitute an acknowledgment by the City that the items thereon were reasonably required for the Change in the Work. (e) Limitations on Changes
The Contractor shall not be entitled to any amount for indirect costs, damages or expenses of any nature, including, but not limited to, so-called “impact” costs, labor inefficiency, wage, material or other escalations beyond the prices upon which the proposal is based and to which the parties have agreed pursuant to the provisions of this section, and which the Contractor, its Subcontractors and Sub-Subcontractors or any other person may incur as a result of delays, interferences, suspensions, changes in sequence or the like, for whatever cause, whether reasonable or unreasonable, foreseeable or unforeseeable, or avoidable or unavoidable, arising from the performance of any and all changes in the work performed pursuant to this section. It is understood and agreed that the Contractor’s sole and exclusive remedy in such event shall be recovery of its direct costs as compensable hereunder and an extension of the time of the Contract, but only in accordance with the provisions of the Contract Documents.

It is expressly agreed that Contractor shall not be entitled to claim damages for anticipated profits on any portion of the Work that may be deleted.

The amount of any adjustment for work deleted shall be estimated at the time deletion of work is ordered and the estimated adjustment will be deducted for the subsequent monthly pay estimates. The City reserves its rights under Section 3.20 to audit Contractor’s as-Bid profit in connection with any deductive change, to arrive at a final adjustment. Contractor’s as-Bid profit shall be reduced pro rata according to the proportion of the original contract value less as-Bid profit, represented by the work deleted.

The City reserves the right to contract with any person or firm other than the Contractor for any or all Extra Work.

2.05. UNILATERAL CHANGE IN OR ADDITION TO THE WORK
Notwithstanding the above, the City, directly or through the Engineer, may direct the Contractor in writing to perform changes in or additions to the scope of the Contract. The Contractor shall perform such work and the parties shall proceed pursuant to the provisions of Section 2.04.

2.06. DIFFERING SITE CONDITIONS
The Contractor shall promptly, and before the following conditions are disturbed, notify the City in writing of any:
(a) Material that the Contractor believes may be material that is hazardous waste, as defined in Section 25110.02 of the Health and Safety Code, that is required to be removed to a Class I, Class II, or Class III disposal site in accordance with provisions of existing law; or (b) Subsurface or latent physical conditions at the Site differing from those indicated in the Contract Documents; or
(c) Unknown conditions at the Site of any unusual nature, different materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in the Contract.

The Engineer shall thereupon promptly investigate the conditions. If the Engineer finds that they do involve hazardous waste, or do materially differ and cause an decrease or increase in the Contractor’s cost or time of performance, the Engineer will issue a change order as appropriate. Any increase or decrease of cost resulting from such changes shall be adjusted in the manner provided in Section 2.04 for adjustments as to extra and/or additional work and changes. In the event that a dispute arises between the City and the Contractor, whether the conditions materially differ, or involve hazardous waste, or cause and decrease or increase the Contractor’s cost of, or time required for, performance of any part of the Work, the Contractor shall not be excused from any scheduled completion date provided by the Contract, but shall proceed with all work to be performed under the Contract, the procedures applicable to claims for extra costs shall then apply.

2.07. CLAIMS FOR EXTRA COSTS
(a) Notice of Potential Claims
(1) It is hereby mutually agreed that the Contractor shall not be entitled to the payment of any additional compensation for any cause, including any act, or failure to act, by the Engineer, or the happening of any event, thing or occurrence, unless the Contractor provides the Engineer with written notice of the potential claims as hereinafter specified.

Compliance with this section, however, shall not be a prerequisite as to matters within the scope of the protest provisions in Section 2.03.

The written notice of potential claims shall set forth the reasons for which the Contractor believes additional compensation will or may be due, the nature of the costs involved, and, insofar as possible, the amount of the potential claim. The notice as above required shall be given to the Engineer prior to the time that the Contractor commences performance of the Work giving rise to the potential claim for additional compensation, if based on an act or failure to act by the Engineer, or in all other cases within ten (10) days after the happening of the event, thing or occurrence giving rise to the potential claim. (b) Construction Dispute
(1) The Contractor may submit a dispute to the Engineer concerning any matter for which a protest under Section 2.03, or a notice of potential claim, is filed. Such disputes, or potential claims, shall be submitted to the Engineer within sixty (60) days following the submission of said protest or notice, unless, due to the nature of the dispute or the uncompleted state of the Work, it is impracticable to determine the amount or the extent of the 281

claim within such period. In such cases, disputes shall be submitted at the earliest practicable time in which such a determination can be made. In any event, all disputes shall be filed on or before the date of the final release by the Contractor as provided for in Section 7.09. (2) All disputes shall be in writing and shall set forth clearly and in detail, for each item of additional compensation requested, the reasons for the dispute, reference to applicable provisions of the Specifications, the nature and the amount of the cost involved, the computations used in determining such costs, all pertinent factual data and all the documents necessary to substantiate the dispute. The Contractor shall maintain complete and accurate records of the cost or any portion of the Work for which additional compensation is claimed, and shall provide the Engineer with copies thereof, as required. The Engineer shall provide a written decision to the dispute or potential claim as soon as practicable but not later than 30 days following receipt thereof.
(c) Resolution of Construction Claims
(1) To the extent that the Contractor disputes the Engineer’s Written Decision issued pursuant to Section 4.07(b)(2), or to the extent the Engineer fails to issue a timely written decision, the Contractor may file a written claim, as defined by Public Contract Code section 9204(c)(1), with the City including reasonable documentation to support the claim. Upon receipt of the claim, the City shall conduct a reasonable review of the claim, and within a period not to exceed 45 days, the City shall provide the Contractor with a written statement identifying what portion of the claim is disputed and what portion is undisputed. The time in which the City must provide a written statement may be extended by mutual agreement of the parties as specified by Public Contract Code section 9204(d)(1)(C). The City shall pay any undisputed portion of the claim within 60 days after issuance of its written statement. (2) Claims submitted by the Contractor shall be accompanied by a notarized certificate containing the following language:

Under the penalty of law for perjury or falsification and with specific reference to the California False Claims Act, Government Code section 12650, et. seq., the undersigned, (Name)

Failure to submit the notarized certificate will be sufficient cause for denying the claim.

Any claim for overhead type expenses or costs, in addition to being certified as stated above, shall be supported by an audit report of any independent Certified Public Accountant. Any such overhead claim shall also be subject to audit by the City at its discretion.

Any costs or expenses incurred by the City in reviewing or auditing any claims that are not supported by the Contractor’s cost accounting or other records shall be deemed to be damages incurred by the City within the meaning of the California False Claims Act. (3) Meet And Confer Regarding Unresolved Claims. If the Contractor disputes the City’s written statement issued pursuant to Section 4.07(c)(1) or if the City fails to issue a timely written response, the Contractor may demand in writing an informal conference to meet and confer for settlement of the issues in dispute. Upon receipt of a demand in writing sent by registered mail or certified mail, return receipt requested, the City shall schedule a meet and confer conference within 30 days for settlement of the dispute. The meet and confer conference shall be attended by senior executives of the parties who have authority to settle the controversy. Within 10 business days following the conclusion of the meet and confer conference, the City shall provide the Contractor with a written statement identifying the portion of the claim that remains in dispute and the portion that is undisputed. The City shall pay any undisputed portion of the claim within 60 days after it issues its written statement. (4) Mediation. If the Contractor disputes, in writing, any portion of the City’s written statement as issued under Section 4.07(c)(3), the disputed items shall be submitted to nonbinding mediation according to the provisions of Public Contract Code section 9204(d)(2), and any costs of mediation shall be allocated as set forth in that section. Upon receipt of a claim, the City and the Contractor may agree to waive, in writing, mediation. (5) Failure to Respond or Pay. If the City fails to timely respond to a claim from the Contractor or otherwise fails to meet the time requirements of Public Contract Code section 9204, the claim shall be deemed rejected in its entirety. Additionally, amounts not timely paid in the manner required by Public Contract Code section 9204 shall bear interest at 7 percent per annum.
(6) Subcontractor Claims. If a Subcontractor or a lower tier Subcontractor lacks legal standing to assert a claim against the City because privity of contract does not exist, the Contractor may present to the City a claim on behalf of the Subcontractor or lower tier Subcontractor pursuant to Public Contract Code section 9204(d)(5).

SECTION 3

CONTROL OF WORK

3.01. AUTHORITY OF ENGINEER
(a) The Engineer is the representative of the City and has full authority to interpret the Contract Documents, to conduct the construction review and inspection of the Contractor’s performance, and to decide questions, which arise during the course of the Work and the Engineer’s decisions on these matters, shall be final and conclusive. The Engineer has the authority to reject all work and materials, which do not conform to the Contract Documents, and has the authority to stop the Work whenever such stoppage may be necessary to insure the proper execution of the Contract. The Engineer’s failure to stop the Work shall not obligate the City to accept defective or otherwise unacceptable work or otherwise affect the Engineer’s or City’s authority to reject work for any reason set forth in the Contract Documents. (b) If at any time the Contractor’s work force, tools, plant or equipment appear to the Engineer to be insufficient or inappropriate to secure the required quality of work or the proper rate of progress, the Engineer may order the Contractor to increase their efficiency, improve their character, to augment their number or to substitute other personnel, new or additional tools, plant or equipment, as the case may be, and the Contractor shall comply with such order.

Neither the failure of the Engineer to demand such increase of efficiency, number, or improvement, nor the compliance by the Contractor with the demand, shall relieve the Contractor of its obligation to provide quality work at the rate of progress necessary to complete the Work within the specified time.
(c) The Engineer may authorize minor variations in the work from the requirements of the Contract Documents which do not involve an adjustment in the Contract Price or the Contract Time. These may be accomplished by a Field Order. Contractor shall comply promptly with all Field Orders. If the Engineer and Contractor are unable to agree on entitlement or on the amount or extent, if any, of any adjustment in the Contract Price or Contract time, or cost, as a result of a Field Order, a claim may be made therefor pursuant to Section 2.07. (d) Any order given by the Engineer, not otherwise required by the Contract Documents to be in writing shall, on request of the Contractor, be given or confirmed by the Engineer in writing.
(e) Whenever work, methods of procedure, or any other matters are made subject to direction or approval, such direction or approval will be given by the Engineer.

3.02. DRAWINGS
(a) Drawings furnished herewith are for bidding purposes. The Engineer will furnish the Contractor, free of charge, copies of full size Drawings which are reasonably necessary for the execution of the Work. The Contractor shall have no claim for excusable delay on account of the failure of the Engineer to deliver such Drawings, unless the Engineer shall have failed to deliver the same within two weeks after receipt of written demand therefore from the Contractor.

The Contractor shall keep one copy of said Drawings, in good order, available to the Engineer and the Engineer’s representatives, and convenient to the working site. (b) If the Contractor, in the course of the Work, finds any discrepancy between the Drawings and the physical condition of the locality, or any errors or omissions in the Drawings, 285
George Reed, Inc.

CPC24-209 State Streets Pavement Rehabilitation
142 Working Days
Updated 2/17/23
or in the layout as given by points and instructions, it shall be the Contractor’s duty to inform the Engineer in writing, and the Engineer will promptly verify the same.

Any work done after such discovery, until authorized, will be done at the Contractor’s risk. All Drawings, Specifications, and copies thereof furnished by the Engineer are the property of the Engineer and shall not be reused on other work and, with the exception of the signed Contract sets, are to be returned to the Engineer, on request, at the completion of the Work. All models are the property of the City.
(c) The Drawings shall be supplemented by such Shop Drawings prepared by the fabricator and/or supplier and Working Drawings prepared by the Contractor as are necessary to adequately control the Work. No changes shall be made by the Contractor in any Shop or Working Drawings after they have been reviewed by the Engineer, if the Engineer deems that no further submittals are necessary. The Contractor shall not commence the layout, purchase, fabrication, or construction of any work for which Shop or Working Drawings are required until Engineer has reviewed the specifications and drawings and has indicated in writing no further submittals are required for compliance with the Contract Documents. (d) Shop and Working Drawings for any structure shall include, but not be limited to, detail design calculations, fabrication and installation drawings, lists, graphs, operating instructions, etc., which shall be reviewed and accepted by the Engineer before any such work is performed.
(e) Shop and Working Drawings will be required for cribs, cofferdams, falsework, centering and form work and for other temporary work and methods of construction the Contractor proposes to use. Such Drawings shall be subject to the review and Acceptance of the Engineer insofar as the details affect the character of the finished work, but details of design will be left to the Contractor who shall be responsible for the successful construction of the Work.
(f) Contractor agrees that Shop and/or Working Drawings processed by the Engineer are not Change Orders; that the purpose of these Drawings submitted by the Contractor is to demonstrate to the Engineer that the Contractor understands the design concept, that the Contractor demonstrates its understanding by indicating which equipment and material the Contractor intends to furnish and by detailing the fabrication methods it intends to use. It is expressly understood, however, that favorable review of the Contractor’s Shop and Working Drawings shall not relieve the Contractor of any responsibility for accuracy of dimensions and details, or for mutual agreements of dimensions and details. It is mutually agreed that the Contractor shall be responsible for agreement and conformity of its Drawings with the Specifications. Contractor further agrees that if deviations, discrepancies or conflicts between Shop and/or Working Drawings and Specifications are discovered either prior to or after the Drawings are processed by the Engineer, the Specifications shall control and shall be followed.
(g) Unless otherwise stated, the Engineer shall have thirty (30) days from the date of receipt of Shop and/or Working Drawings for review.
(h) Full compensation for furnishing all Shop and/or Working Drawings shall be considered as included in the prices paid for the Contract items of work to which such drawings relate and no additional compensation will be allowed therefore. Any cost related to the Engineer’s review of any particular set of Shop and/or Working Drawings more than twice, due to incompleteness or unacceptability, shall be borne by the Contractor, and the City reserves the right to withhold such costs from payments due the Contractor. 286

than that resulting from the Contractor’s fault or negligence. Such taking of possession by the City shall not relieve the Contractor from any provisions of this Contract regarding such structure, other than to the extent specified in the preceding sentence, nor shall such taking constitute a final Acceptance of such structure or facility. (c) If, following installation of any equipment or facilities furnished by the Contractor, defects requiring correction by the Contractor are found, the City shall have the right to operate such unsatisfactory equipment or facilities and make reasonable use thereof until the equipment or facilities can be shut down for correction of defects without injury to the City.

4.02. STORAGE OF MATERIALS
Articles or materials to be incorporated in the Work shall be stored in such a manner as to insure the preservation of their quality and fitness for the Work, and to facilitate inspection.

4.03. TRADE NAMES AND ALTERNATIVES
Whenever a material, article, system or sub-system is specified or described by using the name and/or model of a proprietary product or trademark or the name of the manufacturer or vendor, the specified item shall establish the type, function, and quality required. It shall be understood that the words “or approved equivalent” are implied whether or not they follow the proprietary enumeration.

The City reserves the right to determine when proprietary items have no equivalency, and when uniformity of operations, interchangeability of parts, standard parts inventory, etc., are in the City’s best interest.

Requests for review of equivalency will be considered upon submission of sufficient information as described herein, to allow complete review. Such requests shall not be accepted from anyone other than the Contractor. Such submission must be made prior to purchase, fabrication, manufacture or use of the equivalent items under consideration. (a) Contractor’s Risk. If the Contractor includes in its Bid or later proposes any material, product or equipment that the Contractor considers equivalent to that specified, the Contractor assumes all risk of any sort associated with Acceptance or rejection of proposed equivalent items. The Contractor shall have no right to make claim based upon Contractor’s Bid that includes a proposed equivalent item(s) of work which resulted in a lower Bid amount for said item(s) or lower total bid.
(b) Submission Requirements. Each submission for equivalency review shall include:
296
Updated 2/17/23
(1) Justification for use of the proposed equivalent item(s), including evidence, as applicable, that Contract specified material, product or equipment is unobtainable or unobtainable within an acceptable time for contract completion; (2) A description of the difference between specified item(s) and proposed equivalent item(s) and the comparative advantages and disadvantages of each; (3) All relevant data addressing each specified parameter to show equivalency;
(4) A prediction of any effects the proposed change will have on operation and maintenance costs where applicable.
(c) Equivalency. An item will be considered equivalent to the item specified if it is equal to or better in:
(1) Design and strength in all sub-parts, quality, reliability and durability, operation, maintenance and serviceability, as applicable; and (2) Specified parameters in performance in all respects for the specific function(s) indicated in the contract.
(d) Supplemental Requirements. Any tests required by the City to establish quality and performance standards shall be promptly conducted by or through the Contractor at no additional cost to the City. In addition, the Contractor shall:
(1) Submit any additional data requested by the Engineer for the equivalency review; and
(2) Satisfactorily accomplish all changes, including any Engineering associated with use of equivalent items, at no additional cost to the City. (e) Equivalency Determinations. The Engineer shall be the sole judge as to equivalency determinations. The Engineer’s decision shall be final. The Contractor shall have no right of appeal to any decision rejecting the equivalency of any item. (f) Procedure.
(1) Data substantiating a request for a substitution of “an equal” item shall be submitted prior to the Award of the Contract pursuant to Section 3400 of the latest edition of the Public Contract Code.
(2) After the Bid opening, the apparent three low bidders shall have seven (7) calendar days to provide complete substantiating data for all product, material or system substitution requests. After this seven (7)-day period, the City may award the Contract to the apparent low bidder. In no event will product, material or system substitution requests submitted after the Award of Contract be considered. Failure to submit such substantiating data will result in the automatic rejection of the proposed substitution request. The City will have thirty (30) days to review the first ten (10) proposed substitution requests. For each additional five (5) product, material or system substitution requests over and above the initial ten (10), the City will have ten (10) additional days to review the proposed substitution requests. (3) Each substitution request may include one alternate substitution. All alternate substitutions shall be submitted concurrently with substitution requests. Upon review 297
Updated 2/17/23
by the City, proposed substitutions shall be returned to the Bidder marked either “accepted” or “rejected”. The City shall only review alternative substitution requests if the primary substitution request is rejected. If a substitution request, and its alternative, is returned “rejected”, no further substitution requests for that product, material or system will be allowed and the Bidder will provide the specified product, material or system.
(4) If, after all substitution requests have been processed, substitution requests by the apparent low Bidder are rejected by the City, the apparent low Bidder may elect not to execute the Contract. Under no circumstances, will bidders be allowed to alter their Bid Price as originally submitted. This election shall be made in writing no later than five (5) days following the receipt of the reviewed substitution requests. An election by the Bidder not to execute the Contract will result in the forfeiture of the bidder’s Bid bond. If the apparent low Bidder elects not to continue, and the second low Bidder is awarded the Contract, the second low Bidder may then elect not to execute the Contract for the contract price shown on its Bid Form. Subsequent bidders shall have five (5) days following the receipt of the reviewed substitution requests and the Notice of Award in which to make their election. This process shall continue until one Bidder decides to continue with the Award of Contract process. (5) The City may award the Contract at any time after the time for submitting substitution requests expires pursuant to subpart (2), above. In the event the Contract is awarded prior to acceptance/rejection of substitution requests, all outstanding substitution requests shall be reviewed by the City as provided above. If the apparent low Bidder elects not to execute the Contract, the Award of Contract to the apparent low Bidder shall be rescinded and the Contract awarded to the next apparent low bidder. All bidders electing not to execute the Contract expressly agree that the City shall incur no liability for such rescissions. As provided herein, “apparent low bidder” means the lowest responsive and responsible bidder.

4.04. CERTIFICATES OF COMPLIANCE
(a) A Certificate of Compliance shall be furnished prior to the use of any materials for which the Technical Specifications require that such a certificate be furnished. In addition, when so authorized in the Specifications, the Engineer may permit the use of certain materials or assemblies prior to sampling and testing if accompanied by a Certificate of Compliance. The Certificate of Compliance shall be signed by the manufacturer of the material or the manufacturer of assembled materials and shall state that the materials involved comply in all respects with the requirements of the Contract. A Certificate of Compliance shall be furnished with each lot of material delivered to the Work and the lot so certified shall be clearly identified in the Certificate.
(b) All materials used on the basis of a Certificate of Compliance may be sampled and tested at any time. The fact that material is used on the basis of a Certificate of Compliance shall not relieve the Contractor of responsibility for incorporating material in the Work which conforms to the requirements of the Contract Documents and any such material not conforming to such requirements will be subject to rejection whether in place or not. (c) The City reserves the right to refuse to permit the use of material on the basis of a Certificate of Compliance.
(d) The form of the Certificate of Compliance and its disposition shall be as directed by the Engineer.

(a) The Engineer may at any time, by notice in writing to the Contractor, suspend any part of the Work for such period of time as may be necessary to prevent improper execution of the Work on the project by the Contractor, its Subcontractors or agents, and the Contractor shall have no claim for damages or additional compensation on account of any such suspension.
(b) The City may at any time suspend any part or all of the Work upon ten (10) days written notice to the Contractor, who shall thereupon discontinue all work suspended except for all operations to prevent loss or damage to work already executed as may be directed by the Engineer. Work shall be resumed by the Contractor after such suspension on written notice from the City.
(c) In the event of any suspension of the Work in whole or in part under subsection (B) above, the Contractor shall be entitled to an extension of time wherein to complete the Work to the extent of the delay caused to the Contractor thereby. (d) In the event the entire work shall be suspended by order of the City, as herein above provided, and shall remain so suspended for a period of sixty (60) consecutive days, through no fault of the Contractor, and notice to resume the Work shall not have been served on the Contractor as herein above provided, Contractor may, at its option, by written notice to the City, terminate the Contract in the same manner as if the termination had been initiated by the City, and the City shall have no claim for damages because of such termination of the Contract.

6.04. DELAY IN THE WORK – TIME EXTENSIONS
The Contractor shall at all times employ such force, plant, materials, and tools as will be sufficient, in the opinion of the Engineer, to prosecute the Work at not less than the rates fixed under the terms of the Contract and to complete the Work thereof within the time limits fixed therein. If the Contractor refuses or fails to prosecute the Work, or any separable part thereof, with such diligence as will ensure the completion within the time specified in the Contract, or any extension thereof, or fails to complete said work within such time, the City may exercise the termination provisions set forth in Section 6.05, below. (a) Excusable Delays. Excusable delays shall be delays in the controlling operation of the Contractor’s work due to strikes, lockouts by others, fire, unusual delay in transportation, unavoidable casualties, adverse weather conditions which could not have been reasonably anticipated, or any other act(s) of God beyond the Contractor’s control, or by delay authorized by the City, or by any cause which the City shall decide to justify the delay. Except as provided in Section 6.04(f), below, in the event of an excusable delay, the time of completion shall be extended for such reasonable time as the City may decide. The Contractor’s right to an extension of time for an excusable delay is expressly subject to Contractor’s giving written notice of such claim within ten (10) days following the date the Contractor knew or should have known of the delay. Failure to give such notice shall be construed as a waiver of such right. It is understood and agreed that extensions of time shall be the Contractor’s sole and exclusive remedy for excusable delays.
316
Updated 2/17/23
(b) Compensable delays. Compensable delays shall be delays in the controlling operating of the Contractor’s work due to acts or neglect of the City, its employees or those under it by contract or otherwise, or by changes ordered in the work. In the event of a compensable delay, the time of completion shall be extended for such reasonable time as the City may decide. In addition, the Contractor may recover its direct costs as provided in Section

6.05. The Contractor’s remedies for compensable delays are expressly subject to Contractor’s giving ten (10) days written notice of such claim from the date the Contractor knew or should have known of the delay. It is understood and agreed that the Contractor’s sole and exclusive remedies for compensable delays shall be an extension of the time and recovery of its direct costs as compensable hereunder, but only in accordance with the provisions of the Contract Documents.
(c) Contractor and City understand and agree that the Contract time for the completion of this project is a very important part of the contract. Extensions of time will only be granted as provided above when events actually cause the Contractor to be delayed in the performance of that schedule activity which is the controlling operation as of the time of the delay. When acts or omissions occur which could cause delay, Contractor will take all reasonable means in order to be able to continue to work as scheduled without any delay, or as short a delay as possible. Additionally, if inclement weather causes accumulation of standing water on the work site or other conditions which might cause delay, Contractor shall take all measures reasonably necessary to permit work to continue as quickly as possible. (d) If adverse weather conditions are the basis for a claim for additional time, such claim shall be documented by date substantiating that weather conditions were abnormal for the period of time and could not have been reasonably anticipated, and that weather conditions had an adverse effect on the scheduled construction. Adverse weather conditions shall be considered only as those conditions that exceed the average annual number of rain days and rain quantities as established by the Annual Local Climatological Summary and NOAA National Technical Memorandum NWS WR-65 (Revised) as published by the United States Government, National Weather Service, National Climate Center, Asheville, North Carolina. (e) The Engineer shall be responsible for determining when adverse weather conditions result in non-workable days. It shall be the Contractor’s duty to stay informed of such determinations by the Engineer. The Contractor may object to such adverse weather determinations by filing with the Engineer a written notice of objection. The notice of objection shall state the basis of the objection and provide supporting documentation, which substantiates that weather conditions were abnormal for the period of time and could not have been reasonably anticipated, and that weather conditions had an adverse effect on the scheduled construction. All such notices of objection shall be filed within three (3) days of the day in dispute. It is hereby agreed that the Contractor’s failure to submit a written notice of objection within three (3) days of the Engineer’s adverse weather determination shall constitute a waiver by the Contractor of all its rights to further protest, judicial or otherwise. (f) The Engineer will, within a reasonable period of time, issue a ruling on the Contractor’s notice of objection. All such rulings by the Engineer shall be final, unless the Contractor files a written protest within fifteen (15) days of the Engineer’s ruling. This protest shall clearly state the basis of the dispute. Such protest will be forwarded promptly to the City, which will issue a decision on each such protest. The City decision will be final. Pending the City decision, the Contractor shall proceed with its work in accordance with the Engineer’s ruling and/or instructions. It is hereby agreed that the Contractor’s failure to file a protest within fifteen days (15) of the Engineer’s ruling shall constitute a waiver by the Contractor of all its rights to further protest, judicial or otherwise.

Updated 2/17/23
(g) The number of days that are anticipated to be non-workable due to adverse weather conditions shall be as set forth in Section 4.0 of the Special Conditions. Days deemed non-workable by the Engineer in excess of such anticipated number shall be considered excusable delays.
(h) Unexcused delays shall be delays in the Contractor’s work due to acts or neglect of the Contractor, its employees, Subcontractors or those under it by contract or otherwise. In the event of an unexcused delay, the Contractor expressly agrees that it shall not be entitled to either an extension of time or recovery of its costs.
(i) A request for an extension of time, or the granting of an extension of time, shall not constitute a basis for any claim against the City for additional compensation or damages unless caused by the City or another Contractor employed by the City.

6.05. DAMAGES FOR DELAY
In the event of compensable delay, the City shall only be liable for idle equipment, idle workers and the necessary costs of transporting equipment. The City shall be liable to the extent that the compensable delay is concurrent with excusable delays or Contractor caused delays to the controlling operation. The allowable costs shall be as for force account work under Section 2.04 with the following exceptions:
(a) The Delay Factor in the Labor Surcharge and Equipment Rental Rules applies to each equipment rental rate;
(b) The daily number of payable hours shall equal the normal working hours during the delay, not to exceed eight (8) hours per day; and

Upon service of such notice of termination, the Contractor shall discontinue the Work in such manner, sequence, and at such times as described below. The Contractor shall have no claim for damages for such discontinuance or termination, nor any claim for anticipated profits on the Work thus dispensed with, nor any other actually performed up to the time of discontinuance, including any Extra Work ordered by the Engineer to be done, nor for any claim for liquidated damages.

7.04. PROGRESS PAYMENTS
(a) The City will pay the Contractor ninety-five percent (95%) of the amount of each progress estimate within thirty (30) days after receipt of an undisputed and properly submitted progress estimate from the Contractor, unless the City has made a finding prebid pursuant to Public Contract Code section 7201(b)(4) justifying a larger retention. If the City fails to pay an undisputed progress estimate within the allotted thirty (30) days, the City shall pay interest to the Contractor equivalent to the legal rate set forth in subdivision (A) of section 685.010 of the Code of Civil Procedure. Five percent (5%) of the amount of each estimate shall be retained by the City until final completion and Acceptance of all work under the Contract. (b) Upon receipt of a payment request, the City shall act in accordance with both of the following:
(1) Each payment request shall be reviewed by the City as soon as practicable after receipt for the purpose of determining that the progress estimate is a proper payment request.
(2) Any payment request determined not to be a proper payment request suitable for payment shall be returned to the Contractor as soon as practicable, but not later than seven (7) days, after receipt. A request returned pursuant to this section shall be accompanied by a document setting forth in writing the reasons why the payment request is not proper.
(c) The number of days available to the City to make a payment without incurring interest pursuant to this section shall be reduced by the number of days by which the City exceeds the seven-day return requirement set forth in paragraph (2) of subdivision (b). (d) The Contractor may, in accordance with the provisions of Public Contracts Code section 22300, substitute securities for any monies which the City may withhold to insure performance under the Contract.
(e) When, in the judgment of the Engineer, the Work is not proceeding in accordance with the provisions of the Contract, or when in the Engineer’s judgment the total amount of the Work done since the last estimate amounts to less than one thousand dollars ($1,000.00), no pay estimate will be prepared and no progress payment will be made. (f) No progress estimate or payment shall be considered to be an approval or Acceptance of any work, materials or equipment. Estimated amounts and values of work done and materials and equipment furnished will be conformed with actual amounts and values as they become available in subsequent progress estimates, progress payments and the final estimate and payment. All estimates and payments will be subject to correction in subsequent progress estimates and payments and the final estimate and payment. (g) It is mutually agreed between the parties to the Contract that no payments made under the Contract, including progress payments and the final payment shall be evidence of the performance of the Contract, either wholly or in part, and no payment shall construed to be an Acceptance of any defective or incomplete work or improper materials. 324

333
State Streets Pavement Rehabilitation Project

3.09 BAT HABITAT ASSESSMENT
The Contractor shall refer to the Bat Habitat Assessment Results Report found in the Appendix.

Mitigation Measure (MM) BIO-2b requires trees rated as 2 to go under a survey for bats for a minimum of 2 nights during maternity season (May 1st to August 31st) if bat roosts are found in any of the trees during the evening survey, MM BIO-2b requires the rating to be changed to 3 and subsequent implementation of MM BIO-2c to avoid and minimize impacts on bats and bat roosts.

3.10 ARBORIST REPORT
The Contractor shall refer to the Arborist Report found in the Appendix.

Roots greater than 4 inches in diameter are usually structural roots. Removal of structural roots may greatly reduce the anchorage of the tree and increase the probability of the tree falling over. Work within the structural root zone should be avoided to the maximum extent possible.

Where avoidance is not possible, damage to tree roots should be minimized.

The following recommendations will help protect trees during construction.

The canopy of retained trees that overhang the work area should be pruned to the minimum height required for construction. Pruning should be conducted by an ISA certified tree worker or arborist in accordance with American National Standard Institute (ANSI) A300 Pruning Standard or adhere to the most recent edition of ANSI Z133.1.

Areas within the critical root zone of retained trees which will not be directly impacted by construction should be avoided. No driving, parking, or storage of equipment or materials should occur within avoided areas of the critical root zone. Entry of construction personnel into the avoidance area should not be allowed except for activities undertaken for the protection of the tree.

Roots should be uncovered using hand tools, air spades, or water spades. After the roots are uncovered, root pruning should be conducted along the limit of work. Roots should be pruned to the same depth, and no more, as adjacent excavation. Roots should be pruned by a method that cuts them cleanly such as a rock saw, vibrating knife, narrow trencher with sharp blades, or hand excavation and sawing. Roots should not be severed with backhoes, excavators, bulldozers, graders, or other rough grading equipment that may pull or shatter tree roots.

Exposed roots should be kept moist to minimize water loss, and the soil should be replaced as quickly as possible. The purpose of root pruning is to remove only those roots that need to be removed to complete construction, without further damaging the root system.

If during project implementation, a root greater than 2 inches diameter is encountered that needs to be cut, the tree should be further evaluated by a certified arborist to determine if the tree should be removed all together to eliminate a falling hazard. 334

SPREADING AND COMPACTION EQUIPMENT
337
State Streets Pavement Rehabilitation Project
After compaction, the asphalt concrete shall have a density of not less than 95 percent of the relative compaction of the Laboratory Tested Maximum Density (LTMD), as determined in the field by California Test Method 375 or in a method as approved by the City Engineer.

Spreading and compacting equipment shall be as specified in Section 39-2 of the State Standard Specifications. In addition, pneumatic-tired rollers shall be required to be used on all types of asphalt concrete paving unless otherwise approved by the City Engineer. The Contractor shall furnish a sufficient number of rollers to obtain the specified compaction and surface finish required by these specifications.

All rollers shall be equipped with pads and water systems which prevent sticking of asphalt mixtures to the pneumatic- or steel-tired wheels. A parting agent, which will not damage the asphalt mixture, as determined by the Engineer, may be used to aid in preventing the sticking of the mixture to the wheels. Asphalt concrete and asphalt concrete base shall be compacted by any means to obtain the specified relative compaction before the temperature of the mixture drops below 150°F. Additional rolling to achieve the specified relative compaction will not be permitted after the temperature of the mixture drops below 150°F or once the pavement is opened to public traffic. When vibratory rollers are used as finish rollers the vibratory unit shall be turned off.

If the test results for any lot of asphalt concrete indicate that the relative compaction is below

95.0 percent, the Contractor will be advised that he is not attaining the required relative compaction and that his materials or his procedures, or both, need adjustment. Asphalt concrete spreading operations shall not continue until the Contractor has notified the Engineer of the adjustment that will be made in order to meet the required compaction. The test results for any lot of asphalt concrete indicate that the relative compaction is less than 93.0 percent, the asphalt concrete represented by that lot shall be removed, except as otherwise provided below.

Asphalt concrete spreading operations shall not continue until the Contractor makes significant adjustments to his materials or procedures or both in order to meet the required compaction.

The adjustments shall be as agreed to by the Engineer. However, if requested by the Contractor and approved by the Engineer, asphalt concrete or asphalt concrete base with a relative compaction of 89 percent or greater may remain in place and the Contractor shall pay to the City an amount of reduced compensation for such lot with low compaction. The City may deduct the amount of reduced compensation from any monies due, or that may become due, the Contractor under the contract. The amount of reduced compensation the Contractor shall pay to the City will be calculated using the total tons represented in the lot with low compaction times the contract price per ton for the contract item of asphalt concrete involved times the reduced compensation factors per Section 39-2 of the State Standard Specifications.

Care shall be exercised to avoid raking and spreading asphalt concrete at joints; instead, asphalt concrete shall be pulled back and formed a ridge for rolling by compacting equipment.

The area to which paint binder has been applied shall be closed to public traffic. Care shall be taken to avoid tracking binder material onto existing pavement surfaces beyond the limits of construction.

PAVEMENT STRUCTURAL SECTION
Where the existing pavement is to be reconstructed by constructing a new pavement structural section adjacent to the existing pavement, the edge of the existing pavement section shall be saw-cut on a neat line down to the bottom of the existing pavement, prior to excavation and placement of new full pavement structural section as shown on the plans. All patch backs shall be completed by 2” T-Grind and completed within (5) five days of removing pavement. 338
State Streets Pavement Rehabilitation Project
Full pavement structural section shall be considered as included in the price for other items and no additional compensation will be allowed therefore.

Preparation of roadway, concrete curb, gutter, sidewalk, and driveways, including saw cut, excavation, fill, and disposing existing materials shall be considered as incidental to the Contract unit prices for other items and no additional compensation will be allowed therefore.

MEASUREMENT AND PAYMENT
Payment of hot mix asphalt includes full compensation for furnishing all labor, materials, tools, equipment, and incidentals for performing all work involved in placing asphalt concrete (Type A, 1/2” and ¾” aggregate). HMA to be placed in three, two- inch lifts with the two bottom lifts to be Type A, ¾” maximum aggregate, asphalt concrete and the top lift to be Type A, ½” maximum aggregate, asphalt concrete. This item shall include placing hot mix asphalt at areas where pavement was sawcut and removed for installation, hand working around existing appurtenances or obstructions, adjustment of castings, tack coat, temporary pavement delineation, temporary tapers, and hot mix asphalt required for placement of speed humps.

6) Authorize the City Manager, or his designee, to execute amendments to extend the term of these contracts, if necessary.

BACKGROUND
In the course of implementing City infrastructure projects and other initiatives, staff engage in real property transactions requiring professional real property services. These properties require a wide range of services including but not limited to, acquisition and relocation assistance, appraisal, appraisal review, environmental site assessment Phase I & II escrow and title services, property management, property maintenance services, as well as issuance of a variety of real property permits. The City’s Real Property Asset Management Division is responsible for ensuring that these real property activities are performed in accordance with Federal, state and local policy guidelines and procedures.

In July 2023, the Real Property and Property Management Division was tasked with maintaining non-operating City vacant properties. The division initially collaborated with Public Works and Parks Department staff to maintain parcels. However, the scope of work exceeded eligible fund sources and charter requirements for designated tasks. Thereafter, the Property Division solicited independent licensed landscape contractors to provide, weed abatement and debris removal services to the City. Only two (2) qualified, licensed landscape maintenance companies responded, BrightView Landscaping Services, Inc., and Scott & Sons.

On August 23, 2023, the City of West Sacramento entered into a contract for services with BrightView Landscaping Services, Inc., for the purpose of providing weed abatement and debris removal services for specific non-operating city properties identified in a scope of services and a set fee schedule. The contract provided a not to exceed limit of $50,000 for the term of the contract (October 2, 2023, through October 1, 2025.) The contract has reached its not to exceed limit and additional non-operating parcels requiring weed abatement and debris removal services have been identified.
