3.14-1h: Participate in Improvements to the Sunrise Boulevard/Douglas Road Intersection (Intersection 9). Improvements must be made to ensure that the Sunrise Boulevard/Douglas Road intersection operates at an acceptable LOS. Specifically, all approaches must be reconfigured to consist of two left-turn lanes, three through lanes, and one right-turn lane. However, with implementation of this improvement, the intersection would continue to operate at an unacceptable LOS E or LOS F.

To further improve operations at the intersection, additional roadway connectivity is required. To achieve this connectivity, the Zinfandel Drive Extension must be implemented (to accommodate traffic generated within the SunRidge Specific Plan area), International Drive must be extended to Sunrise Boulevard and into and through the Rio del Oro project site, and Rancho Cordova Parkway (and its connection to U.S. 50) must be implemented.

Improvements to this intersection are contained within the SunRidge Specific Plan Public Facilities Financing Plan. The extension of Zinfandel Drive is identified as part of the Mather Field Specific Plan Public Facilities Financing Plan. Funding has been identified for Rancho Cordova Parkway and the interchange and for the extension of International Drive to Sunrise Boulevard within the City’s CIP program.

3.14-7g: Participate in Improvements at the Mather Field Road/International Drive Intersection (Intersection 13). Southbound left-turn and westbound right-turn volumes at the Mather Field Road/International Drive intersection are substantial enough that additional lanes at this intersection would not reduce impacts at the intersection; therefore, the intersection would continue to operate at an unacceptable LOS E or LOS F. However, additional roadway connectivity in the area, through measures such as implementation of the Kiefer Boulevard Extension to Sacramento, extension of Routier Road to the south, completion of the International Drive–Old Placerville Road connection, and construction of the potential tunnel under Mather Field, has the potential to shift traffic volumes to reduce traffic impacts at the intersection. These additional roadway connectivity measures are identified in the City’s Circulation Element/Plan and included in the City’s CIP. Implementation of these improvements would assist in reducing traffic impacts on this intersection by providing acceptable operations.

Improvements to this intersection must be coordinated with the County and other regulatory agencies because of the proximity of some of these improvements to Mather Field.

3.14-7h: Participate in Improvements to the Zinfandel Drive/International Drive Intersection (Intersection 14) Improvements must be made to improve LOS at the Zinfandel Drive/International Drive intersection. Specifically, this intersection should be reconfigured to provide three left-turn lanes, four through lanes, and one right-turn lane. Additionally, capacity enhancement is needed for the eastbound right-turn movement.

These improvements would reduce the cumulative impact caused by the proposed project and alternatives under consideration by providing acceptable LOS. However, widening International Drive to four through lanes is inconsistent with the City’s Circulation Element/Plan because City policy requires roadway cross sections of six lanes or fewer.

To be consistent with the City’s Circulation Element/Plan, aggressive at-grade improvements are required, such as partial grade separation, capacity-enhancing right-turn treatments on all approaches, or implementation of a continuous-flow intersection. Additionally, improved roadway connectivity, such as the extension of Kiefer Boulevard, International Drive–Old Placerville Road connection, and/or construction of the tunnel under Mather Field would shift traffic volumes and reduce traffic at the intersection.

The additional roadway connections described above and aggressive at-grade intersection treatments are identified in the City’s Circulation Element/Plan and included in the City’s CIP.

3.15 AIR QUALITY

3.15-1: Implement Measures to Control Construction-Generated Air Pollutant Emissions. To reduce short-term construction emissions, the project applicant(s) for all project phases shall implement the measures described below. In addition to the measures identified below, construction operations shall comply with all applicable SMAQMD rules and regulations. ► Phase 1 of all action alternatives for Rio del Oro would result in construction-generated emissions that exceed the SMAQMD threshold of significance, even after implementation of the SMAQMD “standard construction mitigation.” Therefore, the project applicant(s) shall pay SMAQMD an off-site mitigation fee for implementation of any of these alternatives for the purpose of reducing impacts to a less-than-significant level. The specific fee amounts shall be calculated when the construction emissions can be more accurately determined. This calculation would occur when an alternative has been selected, the project has been approved, and the Phase 1 improvement plans have been prepared. Calculation of fees associated with future, subsequent project phases shall be conducted before the approval of grading plans. It is estimated, based on information available at this time, that the off-site construction mitigation fees would range from $4,404,845 to $5,461,587 for development Phase 1, depending on which alternative is selected.
► The project applicant(s) for all project phases shall pay into SMAQMD’s off-site construction mitigation fund to further mitigate construction-generated emissions of NOX that exceed SMAQMD’s daily emission threshold of 85 lb/day. The calculation of daily NOX emissions is based on the 2006 cost of $14,300 to reduce 1 ton of NOX.

3.15-7c: Incorporate Green Building and Development Measures. Each increment of new development within the project site requiring a discretionary approval (e.g., proposed tentative subdivision map, conditional use permit), shall be subject to a requirement, the details of which shall be established through project-specific environmental review, that GHG emissions from t construction and operation of the increment of development at issue will be reduced by 30% from business-as-usual 2006 emissions. In determining 2006 business-as-usual emissions, the assumptions and analysis regarding traffic and operational conditions of the project used in the EIR/EIS may be utilized.

For each increment of new development, the developer shall submit to the City, prior to the release of any project-specific environmental document, a proposed mitigation plan that lists the measures selected to be implemented as part of the proposed development increment and/or consideration of previously implemented measures in the specific plan area, including analysis demonstrating the associated reduction in GHG emissions. The list shall reflect the then-current state of the regulation of GHG emissions and climate change, which is expected to continue to evolve under the mandate of AB 32.

any changes considered by City staff to be necessary and potentially feasible, as part of the projectspecific environmental review for the proposed increment of new development. After receiving and considering any public input on the proposed mitigation strategy, the City shall ultimately approve the strategy (with modifications, if considered necessary and feasible) prior to granting any requested discretionary approval for that increment of development. In determining what sort of measures should appropriately be imposed by a local government under the circumstances to attain the overall, project-wide 30% emissions requirement, the City shall consider the following factors:
► The extent to which rates of GHG emissions generated by motor vehicles traveling to, from, and within the project site are projected to decrease over time as a result of regulations, policies, and/or plans that have already been adopted or may be adopted in the future by ARB or other public agency pursuant to AB 32, or by EPA;
► The extent to which mobile-source GHG emissions, which at the time of writing this EIR comprise a substantial portion of the state’s GHG inventory, can also be reduced through design measures that result in trip reductions and reductions in trip length; ► The extent to which GHG emissions emitted by the mix of power generation operated by SMUD, that will serve the project site, are projected to decrease pursuant to the Renewable Portfolio Standard required by SB 1078 and SB 107, as well as any future regulations, policies, and/or plans adopted by the federal and state governments that reduce GHG emissions from power generation;
► The extent to which replacement of CCR Title 24 with the California Green Building Standards Code or other similar requirements will result in new buildings being more energy efficient and consequently more GHG efficient;
► The extent to which any stationary sources of GHG emissions that would be operated on a proposed land use (e.g., industrial) are already subject to regulations, policies, and/or plans that reduce GHG emissions, particularly any future regulations that will be developed as part of ARB’s implementation of AB 32, or other pertinent regulations on stationary sources that have the indirect effect of reducing GHG emissions;
► The extent to which the feasibility of existing GHG reduction technologies may change in the future, and to which innovation in GHG reduction technologies will continue, affecting costbenefit analyses that determine economic feasibility; and ► Whether the total costs of proposed mitigation for GHG emissions, together with other mitigation measures, required for the proposed development, are so great that a reasonably

prudent property owner would not proceed with the project in the face of such costs.

In considering how much, and what kind of, mitigation is necessary in light of these factors, the City shall consider the following list of options, though the list is not intended to be exhaustive, as GHG reduction strategies and their respective feasibility are likely to evolve over time. These measures are derived from multiple sources including the Mitigation Measure Summary in Appendix B of the California Air Pollution Control Officer’s Association (CAPCOA) white paper, CEQA & Climate Change (CAPCOA 2008), the California Attorney General’s Office (2008) and the Sacramento Metropolitan Air District Draft GHG Measures (2009).

Energy Efficiency
► Include clean alternative energy features to promote energy self-sufficiency (e.g., photovoltaic cells, solar thermal electricity systems).
► Site buildings to take advantage of shade and prevailing winds and design landscaping and sun screens to reduce energy use.
► Install efficient lighting in all buildings (including residential). Also install lighting control systems, where practical. Use daylight as an integral part of lighting systems in all buildings. ► Install Energy Star compliant highly reflective roofing materials. ► Install light-colored “cool” pavements, and strategically located shade trees along all bicycle and pedestrian routes.

Project developers should be encouraged to incorporate “green building” points into the construction and design of all projects (including additions of 25,000 square feet of office/retail commercial or 100,000 square feet of industrial floor area) for which “green building” points are available. Such points may be achieved through conformity with the checklists identified by New Home Construction Green Building Guidelines available at www.builditgreen.org (which were developed to apply to residential construction, but which include measures that are also pertinent to commercial construction), or through any similar list that distinguishes specific measures targeting efficiencies in energy, resource use, or other measures that would also directly or indirectly result in GHG emission reductions. Specific efficiencies that would reduce GHG emissions shall be implemented where feasible, for all project areas including site design, landscaping, foundation, structural frame and building envelope, exterior finishing, plumbing, appliance use, insulation, heating, venting and air conditioning, building performance, use of renewable energy, finishes, and flooring.

Project developers should be encouraged to incorporate any combination of the following strategies to reduce heat gain of the non-roof impervious site landscape (including roads,

► Shaded (Within 5 years of occupancy)
► Paving materials with a Solar Reflective Index (SRI) of at least 29 ► Open grid pavement system (pavement that is less than 50% impervious and contains vegetation in the open cells)
► Parking spaces under cover (defined as underground, under deck, under roof, or under building). Any roof used to shade or cover parking should have an SRI of at least 29. ► Optional level of LEED certification, such as silver or gold which can allow for further reductions in energy consumption and GHG emissions.

Water Conservation and Efficiency
The Project includes water conservation as part of the project. In addition, the project would comply with Title 22, Chapter 32.180, “Water Use and Conservation,” of the City’s Municipal Code, which specifies design criteria for irrigation systems and requirements for plant selection.

These requirements include but are not limited to: installation of irrigation systems that minimize overspray and runoff, use of control valves to account for different site-specific characteristics and use of rain shutoff systems, and installation of plants that are suited to the local climate and require moderate amounts of water (Sections 22.180.070 and 22.180.080). In addition, the following should be considered:
► With the exception of ornamental shade trees, use water-efficient landscapes with native, drought-resistant species in all public area and commercial landscaping. ► Install the infrastructure to use recycled water for landscape irrigation. (Part of the project) ► Install water-efficient irrigation systems and devices, such as soil moisture-based irrigation controls.
► Design buildings and lots to be water-efficient. Install water-efficient fixtures and appliances. (e.g., Ultra low-flow toilets, no flow urinals etc.)
► Restrict watering methods (e.g., prohibit systems that apply water to non-vegetated surfaces).

Prohibit businesses from using pressure washers for cleaning driveways, parking lots, sidewalks, and street surfaces unless required to mitigate health and safety concerns.

Re: EIR and Emission Reduction Measures Review
Project Sunrise, Rancho Cordova, CA
Dear Mr. Chandler,
As requested, NV5 has carried out a review of the plans for the Rancho Cordova Project Sunrise (Facility), in comparison to Rio Del Oro Air Quality and Emissions Reduction Plan (Plan). The purpose of the review is to compare project elements and to determine if the Facility would be compatible with the measures listed in the Plan. The following documents were reviewed:
• Draft Rio Del Oro Specific Plan (RDOSP), City of Rancho Cordova, California, August 2016;
• Final EIR/Environmental Impact Statement (EIR/EIS) for the Rio del Oro Specific Plan Project, June 2010;
• Rio Del Oro Air Quality and Emission Reduction Plan, November 2006, Updated January 2010;
• Conceptual Site Plan (Concept Plan) for the Project Sunrise Rancho Cordova, June 17, 2021;
• Traffic Data for Entitlement Use- CA Receive Center (Trip Generation Count), August 2, 2021;
• Rancho Cordova Project Zoning Analysis Peer Review, May 28, 2021; and • Sacramento Metropolitan Air Quality Management District (SMAQMD) Recommended Guidance for Land Use Emission Reductions Version 4.3, February 10, 2021.

Project Sunrise Receiving Center Facility
The proposed site is located within the Plan Area of Rio Del Oro. Based on the information provided, the Facility is approximately 82 acres and is composed of a warehouse building, employee parking, trailer storage, loading docks, and stormwater management infrastructure. The building will be approximately 629,190 square feet and will include space for storage and offices.

Loading docks will be located on three (3) sides of the warehouse. The proposed parking includes:

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
2 • 995 Standard Parking;
• 24 ADA Compliant Parking;
• 16 Motorcycle Parking;
• 139 Truck Dock Bays; and
• 686 Trailer Storage.

Per the Trip Generation Count, there will be 2 shifts per day, and the facility is expected to have 732 employees per shift.

The Rio Del Oro Air Quality and Emission Reduction Plan (Plan) The City of Rancho Cordova General Plan Policy AQ.1.2.3 requires all new development projects that exceed the SMAQMD operational threshold of significance to incorporate design, construction and/or operational features that will result in a reduction in emissions when compared to an “unmitigated baseline” project. Per this requirement, the Plan provides a list of emission reduction measures that will be included in the development of the Rio Del Oro project.

As part of this review, the operational data, conditions, and measures for the proposed Facility were compared to the measures listed in the Rio Oro Plan to determine if those are in agreement with measures listed in the Plan.

Review Summary
NV5’s review focused on whether the operations at the Facility would fit within the emission reduction measures listed in the Rio Del Oro Air Quality and Emission Reduction Plan and if there are any glaring environmental items that may result in a significant impact. The following provides a list of measures in the Plan as well as the proposed construction and operational conditions for the Facility and how they compare. Note: Each measure is consistent (in scope and numbering) with the menu of creditable measures for emissions reduction developed by the SMAQMD.

Measure 1 - Bicycle Lockers and Racks:

Commercial uses are required to install bicycle lockers and/or racks, which will provide employees with safe and convenient bicycle storage. The Rio del Oro Development Standards and Design Guidelines (Section 3.4.2) provide that “on-site amenities for bicycle parking shall be provided in a convenient location within each center and designed as an integral part of the site. The City Zoning Code requires one Class I or Class II bicycle storage space for every 25 vehicle parking spaces and one Class II bicycle storage space for every 33 patron vehicle spaces. This measure is intended to reduce vehicle trips and associated emissions by encouraging employees to ride bicycles to work and for services.

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
3 Proposed Facility: 51 bicycle storage spaces will be included in the proposed project. Per the Concept Plan, 1,035 employee parking spaces are provided. The number of bicycle storage spaces in comparison to the employee parking spaces, fulfills and surpasses the 1 bicycle to 25 vehicle parking space requirement. The location of bicycle racks will be clearly identified prior to City approval and per CALGreen requirements 5% of total parking space will be dedicated to covered, secured, bicycle parking.

Measure 2 - Additional Bicycle Parking Facilities:

As described above with respect to Measure 1, the City Zoning Code requires one Class I or Class II bicycle storage space for every 25 vehicle parking spaces, and one Class II bicycle storage space for every 33 patron vehicle spaces. The Rio Del Oro project has stated that it will provide an additional 20% of required Class I and Class II bicycle facilities within each commercial, office and industrial development in the plan area.

Proposed Facility: As described under Measure 1, 51 bicycle storage spaces will be included in the proposed project in addition to the 1,035 vehicle parking spaces. This results in a 23% additional bicycle parking spaces compared to the requirement set by the City Zoning code and described in Measure 1.

Measure 3 - Shower and Locker Facilities:

In accordance with the City Zoning Code Section 330-145, showers for both men and women as well as lockers shall be located at all commercial development sites with more than 200 employees, as support for bicycle use and walking. One (1) shower and eight (8) lockers with minimum dimensions of 12” x 18” x 36” shall be provided for each two hundred (200) employees.

The design and/or management of the shower and locker facilities shall provide for access by both male and female employees. The shower and locker facilities must be located convenient to one another and located within 200 feet of the employee bicycle parking facilities.

Proposed Facility: One (1) large locker room with coat rack and lockers will be provided for all employees. However, the number of lockers for this facility has not been provided at the time this review is being conducted. There are no showers on the Facility. The Facility is currently not in compliance with the City Zoning Code requirements listed in Measure 3.

Measure 5 - Class I and Class II Bicycle Facilities:

The Rio del Oro project include Class II bicycle facilities as part of roadway improvements on some of the main roads in the plan area. These facilities will be constructed to City standards and will include all appropriate signage and striping. Bicycle facilities will be constructed concurrently with parallel roadways through the plan area, connecting with adjacent facilities to become part of the overall bicycle circulation network within the City.

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
4 Consistent with General Plan policies C.2.5, C.2.6, C.2.7 and associated actions, the City will require that Rio del Oro Specific Plan planned Class I and II bikeway improvements and connections be provided concurrent with associated project and roadway development to the satisfaction of the City as part of conditions of approval for tentative map applications.

Proposed Facility: The Facility is located in the Rio Del Oro project area and will benefit from the development of the bicycle facilities and the expansion of the bicycle pathways to the overall bicycle circulation network within the City of Rancho Cordova.

Measure 6 - Pedestrian Facilities:

The design of the Rio del Oro project features pathways and connections between land uses and buildings as well as to and from bus stops that are direct, shaded, and lighted. All pathways will meet ADA requirements for width, slope, grade and access. Per the City Design Guidelines, sidewalks will be designed and maintained at the following minimum width:
• 5 feet where the sidewalk is separated from the roadway • 7 feet where the sidewalk is not separated from the roadway • 8 feet in front of schools and commercial uses
• Sidewalks internal to the site (and not part of a public right-of-way) shall be a minimum of 6 feet in width.

As described in Section 3.2.4 of the Rio del Oro Design Guidelines, highly visible crosswalks will be constructed at each intersection, incorporating changes in paving materials to safety, visibility and aesthetics. Pedestrian pathways will be shown on improvement plans for each use. They will connect adjacent land uses and provide connections to sidewalks and other pedestrian features within the plan area. Consistent with General Plan Policy C.2.3 and associated actions, the City will require that Rio del Oro Specific Plan sidewalks, high visible crosswalks, trails and other associated planned pedestrian facilities and connections be provided concurrent with associated project and roadway development to the satisfaction of the City as part of conditions of approval for tentative map applications.

Proposed Facility: The Facility is located in the Rio Del Oro project area and will benefit from the development of pedestrian pathways within the area of the project and adjacent to the Facility.

Measure 7 - Commercial Uses Proximate (1/4 Mile) to Planned Transit (7):

The Rio del Oro project includes plans for bus stop improvements, bus turnouts and bus shelters to accommodate future extension of bus service to the project site. The exact location of these facilities will be determined in consultation with City staff and transit district staff. Bus stops will be designed in consultation with the transit service provider and are expected to include transit route information, benches, shelter and lighting, electrical connections, easements and pads.

Planned transit stops within the plan area would be located nearby (within 1/4 mile) to high density ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
5 residential and employment-generating land uses along arterial roadways, and these planned uses will be able to easily access transit services when extended to the site. This planning approach is intended to achieve a nucleus of ridership sufficient to warrant transit service at 15- minute headways.

Proposed Facility: The Facility is located in the Rio Del Oro project area and will benefit from the extension of bus services as an employment-generating land use.

Measure 8 - Transportation Information Kiosk:

The Rio Del Oro project will provide a display case or kiosk within each commercial development, displaying transportation information in a prominent area accessible to employees and residents.

The following is a brief list of the potential information that could be available at the kiosk:
• Carpool and Vanpool Matching
• Telecommuting Information
• Transit Schedules
• Emergency Ride Home Programs
• Park and Ride Information
• Air Quality Information
• Bicycle Discount Program
• TMA Meeting Schedule
• Newsletters
Materials within each transportation information kiosk shall be replenished and/or updated by management personnel for commercial, employment and high-density residential uses as appropriate to maintain currency.

Proposed Facility: The Facility is located in the Rio Del Oro project area and will benefit from the displays of transportation information provided as part of this measure.

Measure 17 - Preferred Carpool/Vanpool Parking:

The City Zoning Code, Section 330-144, states that at least 10 percent of employee spaces will be for carpool/vanpool purposes. The Rio del Oro project will comply with the City Zoning Code requirement for employee parking spaces, as well as carpool/vanpool spaces. Designated carpool/vanpool spaces will be located as close to employee entrances as possible. The location of carpool/vanpool spaces shall be identified on improvement plans, to the satisfaction of City staff, and shall be clearly marked when built. All carpool/vanpool spaces shall be covered, shaded, or in some other obvious way be designated as preferential.

Proposed Facility: Of the 1,035 employee parking spaces on the Facility, 83 spaces will be dedicated to carpool/vanpool parking spaces. This fulfills the CALGreen requirement to dedicate 8% of total parking space for Clean Air Vehicle/Vanpool/EV. However, the proposed number of ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
6 dedicated carpool/vanpool spaces is slightly less than 10% of the total employee parking spaces at this time and therefore does not comply with the City Zoning code or the Rio Del Oro Plan.

Measure 21 - Parking Lot Design:

Surface parking lots utilized by non-residential development within the project will include clearly marked and shaded pedestrian pathways between transit facilities and business entrances. The Rio del Oro Design Guidelines Section 3.4.2.8 provide that surface parking lots shall be designed with clear visible access ways to major building entries and shall contain landscaped areas with large shade trees to provide coverage. The Design Guidelines further require a green landscape buffer between parking areas and pedestrian ways. Pedestrian pathways shall be designed to minimize conflicts with vehicular traffic through the use of measures such as changes in paving and lighting to delineate a pedestrian path. Pathways may utilize tree cover or structures for shading purposes, as appropriate. Pedestrian pathways will be shown on improvement plans for each commercial use prior to City approval.

Proposed Facility: The parking lot design aspects were not reviewed as part of this review process. Rio Del Oro design guidelines including parking lot design requirements shall be taken into consideration prior to the construction of the Facility to ensure compliance with the Plan.

Measure 30 - Mixed Use within a Single Site:

The Rio del Oro project includes a mix of land zoned for commercial uses and multi-family land uses within close proximity, providing at least 3 of the following on-site and/or within 1/4 mile:

Residential Development, Retail Development, Personal Services, Open Space, Office.

Approximately 76% of the plan area is within a 1/4 mile walking distance from parks, open space, commercial and office/light industrial employment areas.

Proposed Facility: As an employment area in an Industrial Park Zone in the Rio Del Oro project area, the Facility and its employees can benefit from this measure.

Measure 32 - Bicycle and Pedestrian Paths:

The design of the Rio del Oro project features pathways and connections between land uses and buildings as well as to and from bus stops that are direct, shaded, and lighted as appropriate. All pathways will meet ADA requirements for width, slope, grade and access, and shall be designed in accordance with City Design Guidelines 2:20 to 2:21, which provide for a linked system of bicycle paths through the plan area by:
• Direct connections to regional bicycle systems (streets with bike lanes, open spaces with bike paths, etc.)
ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
7 • Bicycle routes shall continue to the property boundary to connect to existing systems on adjacent development or to allow future connections when adjacent properties develop
• Provide bicycle facilities and part of roadways/driveways with painted lanes and signage or provide a separate bicycle system
Pedestrian and bicycle pathways will connect adjacent land uses and provide connections to sidewalks and other features within the plan area
Proposed Facility: The Facility is located in the Rio Del Oro project area and will benefit from the development and expansion of bicycle and pedestrian paths as detailed in this measure.

Measure 33 - Elimination of Barriers:

The complete elimination of barriers is not practical in a large mixed-use project such as Rio Del Oro, due to the wide variety of land uses. However, in providing a mix of uses within close proximity, greater opportunities are created to promote non-vehicular use. It is understood that barriers such as walls, fences and berms will be necessary in some areas to provide for security, noise attenuation, to maintain compatibility between uses and for aesthetic enhancements.

The key is to ensure that the development pattern facilitates easy access between uses. The following design techniques shall be incorporated into the layout of residential and non-residential sites.
• Placement of physical barriers between compatible land uses, such as walls and fences, shall be limited.
• Residential subdivisions or housing site layouts shall provide a pedestrian/ bicycle access connection to any adjacent non-residential or public/quasi-public use. • The site design for all parcels shall incorporate a direct on-site connection to an adjacent pedestrian or bicycle facility.

As identified in the Rio Del Oro Design Guidelines and as required by the Rancho Cordova Open Space Standards, extensive pedestrian access to open space, parks and neighboring residential and nonresidential uses is required, and the use of walls or other barriers that preclude connection between uses is limited. Project design will create meaningful public spaces and buildings that form a dialogue between uses and promote interactions. The intent of this design feature is to allow pedestrian and bicycle circulation to occur away from public streets as appropriate, and to increase direct internal connectivity. This is contrast to typical suburban site designs where each building or development is sealed off by curbs, walls, fences or other barriers from its neighbors.

The City will condition (consistent with the policy provisions of the General Plan Urban Design Element) subsequent non-residential development that no parcel perimeter walls (except for noise attenuation) or building orientation shall be included in site design without the provision of pedestrian and bicycle access for adjoining residential uses.

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
8 Proposed Facility: The Facility design aspects were not reviewed as part of this review process.

Rancho Cordova standards as well as Rio Del Oro design guidelines shall be taken into consideration prior to the construction of the Facility to ensure compliance with the Plan requirements.

Measure 42 - Energy Star Roofs:

Rio Del Oro Air Quality and Emission Reduction Plan states that the project will install Energy Star labeled roof materials that meet an ASTM emissivity rating of 0.75 or higher.

Proposed Facility: The roofing products that are to be used on the Facility will exceed the emissivity rating of 0.75. Compliance with this measure will require documentation confirming that the products installed are Energy Star certified and shall be verified by a site review and/or consultation with the lead agency.

Measure 43 – Exceed Title 24:

Rio Del Oro Air Quality and Emission Reduction Plan Measure 43 and SMAQMD Guidance for Land Use Emission Reductions Measure BE-1 state that the project shall reduce building envelope energy efficiency standards beyond California’s Title 24. This reduces building electricity use and building natural gas use and associated emissions. To qualify for this measure, the proponent must agree to exceed the Title 24 standard at the time of project approval by a certain percentage.

Proposed Facility: The Facility is expected to exceed Title 24 requirements by about 20%.

Implementation of this measure shall be verified by review and approval of a Title 24 compliance sheet by the lead agency.

Measure LE-1 – Install High Efficiency Lighting:

SMAQMD Guidance for Land Use Emission Reductions Measure LE-1, recommends the proponent install higher efficiency lighting in public areas, such as streetlights, outdoor stairwells, pedestrian pathways, parks, parking lots, other exterior lighting and around public buildings.

Proposed Facility: High efficiency light fixtures will be installed at the Facility and the project area.

Measure LUT-5 - Transit Accessibility:

SMAQMD Guidance for Land Use Emission Reductions states that locating a project with high density near transit will facilitate the use of transit by people traveling to or from the project site.

The use of transit results in a mode shift and therefore reduced VMT. The project description should include, at a minimum, the following design features:

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
9 • A transit station/stop with high-quality, high-frequency bus service located within a 5- 10-minute walk (or roughly ¼ mile from majority of development), and/or • A rail station located within a 20-minute walk (or roughly ½ mile from station majority of development)
• Fast, frequent, and reliable transit service connecting to a high percentage of regional destinations
Proposed Facility: At the time this review is being conducted, a light rail transit station is located to the north of the proposed Facility. The closest available transit route is Route 175 outside of the project area. Due to the lack of development at the project area, there is no immediate available transit routes by the Facility at this time.

Measure TRT-1&2 – Implement Trip Reduction Program:

SMAQMD Guidance for Land Use Emission Reductions states that Research and SMAQMD experience suggest providing commute trip reduction programs increases sustainable mode share for the commute which results in decrease in vehicle miles traveled. A Transportation Management Association (TMA) is a formally incorporated organization applying carefully selected approaches to facilitate the low and zero-emission movement of people within an area.

To successfully achieve the emission reductions assumed in an Air Quality Mitigation Plan (AQMP) a TMA must provide a minimum level of organization and specific Transportation Demand Management (TDM) services. Services may include but are not limited to:
• Guaranteed Ride Home Program
• Trip Planning Assistance
• Bike Support
• Walk/Pedestrian Support
• Employee Transportation Coordinator Support
Proposed Facility: The following is some of the strategies that the proponent is planning to implement in order to reduce traffic and satisfy TDM requirements:
• Carpool Program: If available, the employer will partner with the local Transportation Management Organization (TMO) or transit agency to provide a carpool matching tool to help employees find a carpool partner.
• Guaranteed Ride Home Program: The employer will implement a GRH program, which will provide employees who are utilizing drive alone alternatives with a guaranteed ride home should their alternative commuting option fall through. This guaranteed ride home will be provided through app-based ride-sharing services. • Pre-tax Commuter Benefits.
• Transit Service: The tenant will engage with the local transit agency to request bus service to the site.

ITEM 11.1. ATTACHMENT 11

EIR and Emission Reduction Measures Review
Project Sunrise Rancho Cordova, CA
10 • Transportation Coordinator: The employer will designate a Transportation Coordinator (TC) in charge of implementing and promoting commuter programs on-site • Employee Notification: Each employee at the Facility will be provided information about commute options and amenities available to them. Information will be provided via the benefits website, new hire orientations, newsletters, all-hands meetings, and / or on TV monitors at the site. The goal is to encourage employees to actively pursue commuting alternatives by providing them easy access to materials, information, and resources.
• Information Boards: The Transportation Coordinator will post employee commute information on a bulletin board, TV monitors, and / or flyers posted in the break room or other high-profile location.
• Transportation Fair: If available, employer will partner with the local TMO and / or transit agency to host onsite transportation fairs and promote commute alternatives.

The feasibility of the items listed above is dependent on the availability of local TMAs and similar programs as well as the development of the area surrounding the Facility and lastly the approval of the proponent, therefore the compliance of the Facility with this measure cannot be determined at this time. Measure 51 of the Rio Del Oro Air Quality and Emission Reduction Plan indicates that the project intends to join together with an existing TMA already operating in the area, known as the Folsom/El Dorado /Cordova TMA.

Conclusion
As mentioned above, the proposed site is located within the Plan Area and therefore is included in the RDOSP Project EIR. After the review of the site-specific information provided by the client, NV5 has determined that the Facility’s proposed plans comply with emission reduction measures regarding: bicycle parking facilities, energy star roofing material, building efficiency exceeding Title 24 requirement provided in Rio Del Oro Air Quality and Emission Reduction Plan. It should be noted that compliance with these measures will require documentation and will be verified by the lead agency.

The parking lot design aspects were not reviewed as part of this review process. Rio Del Oro design guidelines including parking lot design requirements shall be taken into consideration prior to the construction of the Facility to ensure compliance with the Plan. See Measure 21 above for more information.

Rancho Cordova standards as well as Rio Del Oro design guidelines require elimination of unnecessary barriers to promote non-vehicular use. The Facility design aspects were not reviewed as part of this review process. This must be taken into consideration prior to the construction of the Facility to ensure compliance with the Plan requirements. See Measure 33 above for more information.

Furthermore, under this measure, eight (8) lockers need to be provided for every 200 employees. The number of lockers for this facility has not been provided, therefore compliance with this segment of Measure 3 cannot be determined at this time. Additionally, the Facility’s current plan does not comply with Measure 17, requiring 10% of total employee parking spaces to be dedicated to carpools/vanpools. The measures pertinent to transportation, such as proximity to easily available and reliable transit, and TMA membership are other measures that need to be addressed prior to project development with the stakeholders as well as the City in order to ensure compliance. The proposed site will then be determined to be consistent with the Specific Plan and the City’s General Plan, and therefore no further Air Quality and GHG study is expected to be required.

No additional issues that would affect the feasibility of the Facility have been identified during this review.

Memorandum

OVERVIEW AND SUMMARY OF FINDINGS
Geosyntec Consultants, Inc. (Geosyntec) was asked by Panattoni Development Company, LLC (PDC) on behalf of Amazon.com Services, Inc. (Amazon) to perform a peer review of the Geotechnical Engineering Study (Report) prepared by Youngdahl Consulting Group, Inc. (YCG) for a proposed warehouse/distribution facility to be located at the terminus of Gold Dredge Way in Ranch Cordova, California (Site).

The following documents were provided for our review:
 Geotechnical Engineering Study (Report) for GEN 4.3 IXD Facility, Rancho Cordova, California by Youngdahl Consulting Group, Inc. dated 22 June 2021; and  Project Sunrise Site Concept Plan Scheme 12 Drawing No. EX12, Rancho Cordova, California by KPFF Consulting Engineers for Panattoni dated 18 June 2021.

Based on review of the Report the proposed facility will consist of about 650,000 square feet (sf) warehouse/distribution facility and associated parking and trailer storage. YCG anticipates that the building will consist of concrete tilt-up exterior walls, a concrete slab-on-grade floor, and a shallow footing foundation.

YCG was contracted by Elliot Homes, Inc. (Elliot Homes) to conduct a subsurface investigation program to supplement existing investigation data and provide geotechnical engineering recommendations to guide the design and construction of the foundations, slabs, and pavements for the potential development of the Site. Geosyntec has peer reviewed the Report by YCG listed above (YCG, 2021) and has prepared this memorandum to document the findings from our review.

Peer Review Sunrise
The peer review, comments, and recommendations presented in this memorandum are based on the data presented in the Report. The Report appears to generally address the scope of work requested by Elliott Homes, Inc. for the proposed facility development. Geosyntec generally agrees with the recommendations made in the Report that overexcavation and replacement can be used as the means to prepare the site for development, following which shallow foundation system may be an acceptable approach to support the proposed structure. However, there are several key items identified during the review of the Report that should be taken into account when selecting path forward for this development:
 The Report states that “Due to the non-uniform nature of soils, other geotechnical issues may become more apparent during grading operations which are not listed above.” Considering that no new explorations have been performed for this study (i.e., YCG relied on existing exploration only) and that existing exploration coverage is extremely limited within the proposed building footprint, the proposed approach appears to leave high level of risk for surprises during construction.
 The site is underlined by remnants of historical mining operations. The Report recommends removal of mining operations remnants and provides preliminary excavation depths. The excavation depth of 25 feet was preliminarily recommended for the building footprint.

However, summary of exploration on Figure A-2 indicates depth of slickens (historical mining operation remnants) of 33 feet in Boring D-2 and 29 feet in Boring BA-10 (a couple of deeper borings adjacent to building footprint area). It is unclear why excavation depth of 25 feet was selected. From this information it is not clear if the intent is to leave some of the mining remnants material in place or remove all of it.  The Report recommends lateral extent of excavation of 10 feet laterally from the building envelope. It is our experience that lateral extent of remedial excavation should extend laterally at the bottom of excavation a minimum distance equal to the depth of excavation.

This extent is typically measured from the outside edge of the footings.  The Report only recommends partial excavation of mining operation remnants under the parking areas. This approach may result in significant differential settlement in the transition area between fully overexcavated and partially overexcavated mining material remnants.

Geosyntec’s peer review comments were prepared in accordance with generally accepted geotechnical engineering principles and practices. The applicability of the Report and this peer review document should be re-evaluated if significant changes were to occur during the final design of the warehouse.

ORGANIZATION OF THIS MEMORANDUM
This memorandum has been organized to present the following: (i) evaluation of the scope of geotechnical services; (ii) review of available information; (iii) subsurface investigation; (iv) subsurface conditions; (iv) Geosyntec’s peer review of geotechnical recommendations; (v) conclusions and limitations; and (vi) references.

EVALUATION OF THE SCOPE OF GEOTECHNICAL SERVICES
The geotechnical engineering services performed by YCG were intended to provide geotechnical engineering recommendations to guide the design and construction of the foundations, slabs, and pavements for the development of the Site.

Based on experience with similar projects, Geosyntec will evaluate whether the Report, at a minimum, addresses the following:
 feasibility of a shallow foundation system to support the proposed facility, and, if required, suitability of mitigation techniques that enable the use of the proposed foundations;  foundation design parameters and slab-on-grade support recommendations;  seismic design parameters;
 earthwork recommendations including site preparation, fill placement, excavation, suitability of soils for fill materials, compaction, and slopes;  estimates of building settlements considering grading and building loads;  design recommendations for retaining walls and other below-grade structures;  storm water management; and
 pavement design and construction recommendations.

The following sections provide a description of the work performed by YCG followed by Geosyntec’s evaluation of the design recommendations.

REVIEW OF AVAILABLE INFORMATION
According to the Report, YCG performed a site reconnaissance, reviewed available geologic literature, historical aerials, and previous exploration data.

Below is a summary of their main findings:

Peer Review of Geotechnical Report

Peer Review Sunrise
 The Site is currently being used for aggregate mining. The Site is located at the east terminus of Gold Dredge Way. The study area encompasses approximately 80 acres.

Industrial development and a large stormwater basin are located immediately east of the project with the remaining surrounding area generally undeveloped.  The Site has been used for dredge mining operations since at least 1957 according to YCG’s review of historical aerial photographs. Floating dredgers and a single stack were used resulting in rows of coarse material (i.e., tailing) and fine materials (i.e., slickens).

The slickens are deposits left from the pond dredge operation. The tailings have been mined for aggregate materials throughout a majority of the Site. YCG reports that it does not appear that mitigation measures to address the historic mining operations have been performed to make it suitable for improvements and development.  Elevation data was not provided in the Report. YCG does report that relative site elevations difference across the site vary on the order of 10 to 15 feet in some locations as a result of the dredge piles and mining activities.
 According to YCG’s review of previous subsurface studies, including test pits, borings, and cone penetration testing (CPT), the appears to have 3 distinct soil areas including native, tailings deposits, and slickens deposits. YCG notes that this is discernable from well defined aerial images. Native grades are present at the north end of the Site only. The remaining portions of the Site are evidently covered with tailings or slickens deposits or other aggregate mining byproducts. Native grade generally consists of sandy gravels with silt and are considered to be relatively dense. YCG reports that the thickness of these materials is not specifically known but are estimated to extend 50 or more feet bgs.  The depth of the mined area is estimated to be approximately 25 to 30 feet bgs in some locations. The tailings areas are generally flat and slightly above the slickens. Tailings are generally medium dense sands and gravels. Surface slickens materials are generally clay and silts. Slickens deposits are on the other of 100 to 150 feet wide and tailings are on the order of 300 feet wide.
 Based on YCG’s review of the California Department of Water Resources, within ½-mile radius of the Site, groundwater has varied from elevation 17 to 132 feet MSL. YCG anticipates that groundwater is relatively deep and will not impact development. However, they noted that the shallow depth to cemented soils could lead to subsurface perched water conditions.
 According to YCG’s review of the Geologic Map of the Sacramento Quadrangle by Gutierrez (2011), the site is underlain by Pleistocene to Holocene Alluvium. This consists ITEM 11.1. ATTACHMENT 11

of undivided alluvium consisting of flat, relatively undissected fan, terrace, basin deposits, and small active streams.
 The Report does not reference the presence or absence of underground utilities.  The Site is not located in an Alquist-Priolo Zone and no known faults run through the Site.

SUBSURFACE INVESTIGATION PROGRAM
According to the Report, YCG performed field investigations at the Site and neighboring sites in 2003, 2005, and 2018. These investigations are supplemented with investigations performed at the Site and neighboring parcels by Wallace, Kuhl & Associates, Inc. (WKA). WKA excavated nine test pits and one boring at or adjacent the Site during their investigation in 1997. YGC excavated six borings and two test pits at or adjacent the Site during their October 2003 investigation. YCG excavated seven test pits and four borings (one within the Site area) for the neighboring stormwater basin area during their June 2005 investigation. YCG performed four borings and four CPTs at or adjacent the Site during their latest field investigation in 2018. A summary of the investigations are presented below.
 2 test pits (TP-18 and TP-13) were completed within the building footprint for a frequency of 1 exploration per 325,000 SF. This is significantly less than the frequency recommended by the BTS Diligence Guidelines suggesting one exploration per 20,000 SF. The test pits within the building footprint were excavated to a depth of 16 feet bgs, which is shallow considering the fact that excavation of 25 feet is recommended in that area. Deeper borings BA-10, B-3, and D-2 are within a 100 to 300-foot radius of the building footprint and appear to be used for extrapolating subsurface conditions beneath the proposed building.

However, due to the historical mining activities at the Site, there is a greater potential for variable subsurface conditions that may need to be further site-specific explorations before final design.
 2 test pits (TP-12 & TP-21), 5 borings (D-2, BA-2, BA-10, B-11, and B-3), and one CPT (CPT-1) were completed within the proposed pavement area to depths range between approximately 16 and 70 feet bgs.
 15 test pits, 8 borings, and 3 CPTs were completed in neighboring properties within a range of 10 to 1000 feet from the Site boundary.
 In-situ standard penetration tests (SPT) were performed to assess density of subsurface materials within the pavement area, however not within the building footprint. Penetration resistance is indicated on the boring logs (BA-2, BA-10, and BA-11) as blows per foot.

Based on review of the boring logs within the Site boundary, stiff to very stiff soils were ITEM 11.1. ATTACHMENT 11

encountered to depths of 25 feet, with the exception of a soft to medium stiff layer between 15 and 20 feet bgs in BA-10.

Representative soil samples were recovered for visual classification/description from three of the explorations performed within the Site boundary. Samples were sent for laboratory testing that included direct shear, particle size distribution, resistance value, unconfined compressive strength, #200 sieve wash, Atterberg Limits, 1-D consolidation, specific gravity, and maximum dry density/optimum moisture.

SUBSURFACE CONDITIONS
According to the Report and Geosyntec’s review of the geotechnical investigations, the general subsurface stratigraphy throughout the Site can be described as following:
 Tailings: The tailings deposits were previously tall piles of rounded cobbles, but most have been mined during recent years and tailings areas are now generally flat and slightly elevated above the slickens. These materials are generally a mixture of sands and gravels in a medium dense condition.
 Slickens: The slickens materials are generally clays and silts with increasing sand content with depth. Based on our review of Figure A-2 in the Report, the depth of slickens at the Site range between 23 and 33 feet bgs. Explorations within the building footprint were not advanced deep enough to estimate the depth of slickens. However, YCG states in the Report that the mined area is estimated to have reached 25 to 30 feet bgs. This is somewhat inconsistent with Figure A-2 in the Report, which shows depths of slickens encountered as deep as 33 feet bgs. Additionally, considering there are not surface elevation data for boring locations, it is challenging to compare depths at various locations to assess the bottom elevation of slickens.
 Native: The native soils are generally reported to consist of sandy gravels with silt. The Report estimates that these materials extend 50 or more feet below grade. Native grade is exposed at the ground surface in the northeast corner of the Site.

YCG Report indicates that groundwater was not observed in any of the explorations. YCG anticipates that groundwater is relatively deep and will not impact development. However, they noted that the shallow depth to cemented soils could lead to subsurface perched water conditions.

PEER REVIEW OF GEOTECHNICAL RECOMMENDATIONS
The following are Geosyntec’s review comments of the geotechnical assessment and recommendations provided in the Report. Emphasis was placed on evaluating that the minimum set of guidelines described in the first section of this memorandum were addressed.  Feasibility of a shallow foundation system and Grading Recommendations: The Report indicates that the proposed building could be supported on shallow foundation system, provided the Site is prepared in accordance with the site grading and earthwork improvements recommendations provided in Section 6 of the Report. YCG recognizes the presence of loose/soft soils and mine deposits associated with the historic mining operations at the Site as a major design constraint. YCG presents a preliminary overexcavation and recompaction site plan on Figure D-1 in the Report, suggesting unsuitable mining deposits and soft/loose soils in the upper 25-30 feet of subsurface may need to be removed and backfilled with engineered fill. For the building area, YCG recommends that all existing fills within 10 feet laterally of the building should be overexcavated down to firm native soils. Geosyntec agrees with the general approach to overexcavate and replace the slickens soils. However, we are of opinion that the available subsurface data is not sufficient to adequately predict necessary depth of overexcavation.

Furthermore, it is our experience that lateral extent of remedial excavation should extend laterally at the bottom of excavation a minimum distance equal to the depth of excavation.

This extent is typically measured from the outside edge of the footings.  Foundation design parameters and load induced settlements: YCG indicates that shallow should be a minimum of 15 inches wide and founded a minimum depth of 18 inches below the lowest adjacent soil grade. Isolated pad foundations should be a minimum of 24 inches.

The Report indicated that bearing pressure 2,100 pounds per square feet (psf) and 2,500 psf could be used for design of footings with dead load and dead plus live load, respectively. These foundation recommendations are provided on the basis that footings bear on engineered fill or firm native soil. YCG indicates that if the recommendations outlined in the Report are followed, then the expected total settlement of less than 1 inch and ½ inch of differential settlement are anticipated. Geosyntec generally agrees with the recommendations, however, in our experience, higher bearing capacity can be achieved on compacted engineered fill. Finally, these recommendations are contingent upon the successful execution of the remedial overexcavation program. As noted by YCG, the overexcavation and recompaction plan should be revisited following final design and a qualified engineer should be onsite to confirm a firm and unyielding base is achieved. The ITEM 11.1. ATTACHMENT 11

settlement and bearing pressure conclusions should be revisited if a different approach is taken to mitigate the mining deposits at the Site prior to construction.  Suitability of On-site Soils for Fill: The Report states that soil generated from excavations on the Site, excluding deleterious material, may be used as engineered fill. Our review of provided laboratory testing data indicates that there are onsite soils with high percent fines (close to 100%) with liquid limit above 50, i.e. Fat Clays (CH) and Elastic Silts (ML).

Based on our review, the Report does not appear to define any fines content or plasticity limits for Engineered Fill. High fines content soils, in our experience, may not be most suitable fill type for this purpose. Based on our review of the limited Atterberg Limits testing, the clays and silts that make up the slickens materials don’t meet the minimum requirements for select import fill in the Report, with Plasticity Index (PI) exceeding the recommended maximum value of 12 (PI range reported as 23 – 39). Materials with PIs in this range are generally considered to exhibit expansion potential. Potentially expansive onsite soils are not recommended for use as engineered fill below slabs and footings but may be suitable for deeper backfill (>5 feet below finished grade) provided they are prepared and compacted in accordance with the grading and earthwork recommendations in the Report.

YCG states that asphalt concrete and concrete materials may also be mixed into the engineered fills provided they are reduced to not greater than 9 inches in maximum dimensions and placed in low concentration to prevent nesting and allow for conventional testing of relative compaction. Geosyntec generally agrees with this conclusions, provided that oversized material (>3 inches) is removed for engineered fill below slabs and footings or retaining wall backfill. .
 Seismic design considerations: Shear wave velocity measurements were not performed at the Site. YCG evaluated the Site Class based on guidance described in American Society of Civil Engineers (ASCE) publication ASCE/SEI 7-16 and general knowledge of the local geology and characterized the Site as Class D. YCG notes that Site Class C has been used for neighboring sites, however the Site was characterized as D due to the presence of mining deposits. Considering that mining deposits will be remove under the building, this statement should be revisited.

Site Class D is described as Stiff Soil with average blowcounts in the top 100 feet in the range of 15 to 50 blows per foot. Based on the review of the boring logs, the blowcounts generally range between 10 and 50+. The deepest boring with a recorded blowcount reached 42 feet bgs, meaning an average blowcount of the top the 100 feet is not available.

Site Class D (Default) may be the more appropriate designation in this case. Geosyntec emphasizes the Default D classification is only acceptable if YCG can provide evidence that the Site could not be downgraded to E or F with further explorations. Information such this may come from a review of local geology or other neighboring site explorations.

YCG provided seismic design parameters using Site Class D and notes that the structural engineer should review the conditions of the exceptions in ASCE 7-16 Section 11.4.8 and select the final choice of design parameters. While the available information is generally consistent with YCG’s assessment, BTS Diligence Guidelines recommend that shear wave velocity measurement be performed to assist site classification, one of the reasons being that change in site classifications could result in significant change in seismic demand.  Design and construction recommendations for concrete flatwork: Geosyntec reviewed the design recommendations for concrete flatwork. YCG recommends that slab subgrade be properly prepared and compacted. Fill should be moisture conditioned and compacted to the 95 percent of maximum dry density. At a minimum slabs should be underlain by 6 inches of Class 2 aggregate base compacted to 95 percent of maximum dry density. For slabs not subject to vehicle loading, a 4-inch section of concrete will be sufficient. For slabs with heavier expected loads (i.e., forklifts), a thicker section of 6 inches is recommended.

YCG recommends that special attention be given regarding the drainage of the Site if contractor intends to grade during the wet season as the presence of shallow cemented soils could impact the subgrade preparation and require alternative subgrade support methods such as geogrid or chemical stabilization. Geosyntec generally agrees with these conclusions provided the subgrade soils are observed by a qualified engineer prior to concrete placement, and water infiltration be prevented during grading and subgrade preparation.
 Design and construction recommendations for pavement areas: Geosyntec reviewed the design recommendations for pavement considerations in the Report. Pavement recommendations are provided based on an R-Value of 15. The tested soils has an R-Value of 17, however YCG anticipates that grading operations would result in a design value closer to 15. The recommended design thicknesses were calculated in accordance with Caltrans Highway Design Manual. A varying range of traffic indices were evaluated. The proposed sections appear to be generally reasonable for the selected R-Value.

YCG also mentioned that areas with existing mine deposits be overexcavated per the Site Plan presented on Figure D-1 and be backfilled with engineered fill. This overexcavation should extend 3 feet laterally beyond the proposed footprint. According to proposed ITEM 11.1. ATTACHMENT 11

Peer Review of Geotechnical Report
Sunrise

Peer Review Sunrise
excavation approach, mining material remnants will be left in place under the pavement area. YCG states that settlement of the underlying mine deposits may follow after placement of the backfill and surface improvements should delay a minimum of 90 days following completion of backfill activities and before pavement construction. We did not identify any specific means (e.g., settlement monitoring) which may be required to confirm that 90 days wait period was sufficient. Furthermore, leaving mining material remnants in place may results in some long term settlements, total and differential, in the pavement areas. No discussion is provided on this topic.
 Design and construction recommendations for below-grade structures: Geosyntec reviewed the design recommendations for lateral earth and hydrostatic pressures for retaining walls. The selected parameters and recommended design values appear to be appropriate for this type of project and follow the standards of geotechnical practice. As noted in the Report, expansive soils should not be used as backfill material behind retaining walls and the reported values reflect walls bearing on firm native soil or engineered fill.

Geosyntec recommends that free-draining soils be used as backfill for retaining walls.  Expansive Soils: Geosyntec reviewed the Atterberg Limits which suggest a moderate to high expansion potential for the clays and silts that make up the slickens materials. YCG mentioned that expansion index testing was performed on the clay materials found within the slickens, however Geosyntec only found Atterberg Limits results in the Report. YCG states that they believe proposed grading operations will prevent clays from being concentrated as they are mixed with onsite non-plastic materials. Geosyntec generally agrees that this achievable provided that subgrade soils are properly compacted and moisture conditioned and observed by a qualified engineer. Geosyntec adds that the use of expansive materials should be avoided for engineered fill beneath slabs, footings, and pavement.
 Stormwater drainage considerations: YCG did not perform infiltration tests for the project Site nor do they comment on the design or feasibility of infiltration for the Site.

Considering that infiltration is generally not recommended due to the presence of shallow cemented soils that may cause perched water conditions, careful attention should be given to stormwater controls during and after construction at the Site.

CONCLUSIONS AND LIMITATIONS

information appears to generally address the scope of work requested. Geosyntec acknowledges that the Draft Report supports the preliminary site concept, and that verification of the recommendations will be required following finalization of grading and foundation plans.

Geosyntec generally agrees with the recommendations made in the Report that overexcavation and replacement can be used as the means to prepare the site for development, following which shallow foundation system may be an acceptable approach to support the proposed structure. However, there are several key items identified during the review of the Report that should be taken into account when selecting path forward for this development:

 The site is underlined by remnants of historical mining operations. The Report recommends removal of mining operations remnants and provides preliminary excavation depths. The excavation depth of 25 feet was preliminarily recommended for the building footprint.

However, summary of exploration on Figure A-2 indicates depth of slickens (historical mining operation remnants) of 33 feet in Boring D-2 and 29 feet in Boring BA-10 (a couple of deeper borings adjacent to building footprint area). It is unclear why excavation depth of 25 feet was selected. From this information it is not clear if the intent is to leave some of the mining remnants material in place or remove all of it.  The Report recommends lateral extent of excavation of 10 feet laterally from the building envelope. It is our experience that lateral extent of remedial excavation should extend laterally at the bottom of excavation a minimum distance equal to the depth of excavation.

This extent is typically measured from the outside edge of the footings.  The Report only recommends partial excavation of mining operation remnants under the parking areas. This approach may result in significant differential settlement in the transition area between fully overexcavated and partially overexcavated mining material remnants.

Geosyntec generally agrees with the recommendations made in the Report, with exceptions as noted in this memorandum.

NV5 conducted a noise impact analysis to evaluate the potential noise impacts and identify possible noise mitigation measures associated with the proposed Receiving Center within the Plan Area of Rio del Oro located at Rancho Cordova Parkway and International Drive in Rancho Cordova, CA. This study evaluates the short-term noise impacts from the construction activities and the long-term noise impacts from the on-site operations of the proposed Receiving Center on the sensitive receptors located near the site.

1.2. Project Description
The proposed site is a Receiving Center located within the Plan Area of Rio del Oro at Rancho Cordova Parkway and International Drive in Rancho Cordova, CA. The proposed site is located south of White Rock Road, east of Luyung Drive, and north of Douglas Road. The site is under the jurisdiction of the City of Rancho Cordova. The proposed project site is bounded by International Drive to the north; Zuke’s Landscape followed by Luyung Drive to the west; undeveloped land followed by Sunrise Boulevard to the south; and more undeveloped land to the east. Exhibit A indicates the location of the facility.

The site is located in Industrial Park (MP) and Business Park (BP) zones. The land use surrounding the property is designated as Residential and School Campus. Currently the areas north, south, and east of the site are undeveloped, and as such the closest sensitive receptors used in this study represent the proposed developments according to the Rio Del Oro Specific Plan. The closest sensitive receptors would be residential homes approximately 220 feet north of the site and 975 feet south of the site, as well as a school campus approximately 825 feet south of the site.

Based on the site Concept Plan (Exhibit B), the facility will consist of a truck entry driveway, truck exit driveway, trailer storage (i.e. truck parking), and employee car parking spaces. Access to the site for cars will be via the northeast driveways on International Drive and the east driveways on Rancho Cordova Parkway. Trucks will enter via the southwest driveway on Gold Dredge Way, and the exit will be via the southeast driveway along Gold Dredge Way.

2. Noise and Vibration Fundamentals

2.1. Sound, Noise and Acoustics
Sound is a mechanical radiant energy that is transmitted by longitudinal pressure waves in a material medium, such as air in the case of traffic and stationary noise, and is the objective cause for human hearing. Sound is technically described in terms of the loudness (amplitude) and frequency (pitch) of the sound. Noise is defined as an unwanted sound.

2.2. Frequency
When sound travels through air, the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound and is measured in Hertz (Hz) which is defined as cycles per second. Our hearing systems are not equally sensitive to all sound frequencies. Thus, not all frequencies are perceived as being equally loud at the same sound pressure level, and when calculating overall environmental noise ratings it is necessary to consider sounds at some frequencies as more impactful than those at other frequencies. Lowfrequency sounds are low in pitch (bass sounding) and high-frequency sounds are high in pitch (squeak). The human ear can hear from a bass pitch starting at 20 Hz all the way to the high pitch of 20,000 Hz.

2.3. Sound Pressure Levels and Decibels
Sound pressure level (SPL or Lp) is a logarithmic measure of the effective pressure of a sound relative to a reference value. The sound pressure levels are measured in decibels abbreviated dB. The human ear is not equally sensitive to sound at all frequencies. The “A-weighted scale,” abbreviated dBA, reflects the normal hearing sensitivity range of the human ear. On this scale, the range of human hearing extends from approximately 3 to 140 dBA. Exhibit C provides examples of A-weighted noise levels from common sounds.

Exhibit C – A-weighted common noise level scale
ITEM 11.1. ATTACHMENT 11

NV5.COM | 8

2.4. Addition of Decibels
Because decibels are on a logarithmic scale, sound pressure levels cannot be added or subtracted by simple plus or minus addition. To add two or more noise levels, if the difference between the highest and next highest noise level is: 0–1 dB then add 3 dB to the higher level to give the total noise level, 2–3 dB then add 2 dB to the higher level to give the total noise level, 4– 9 dB then add 1 dB to the higher level to give the total noise level, 10 dB and over, then the noise level is unchanged (i.e. the higher level is the total level)

2.5. Human Response to Changes in Noise Levels
In general, the healthy human ear is most sensitive to sounds between 1,000 Hz and 5,000 Hz, and it perceives a sound within that range as being more intense than a sound with a higher or lower frequency with the same magnitude. For purposes of this report as well as with most environmental documents, overall sound levels are determined by applying frequency weighted adjustments to spectral sound levels. The A-scale weighting scale is used to mimic human hearing response, so sound is reported in terms of A-weighted decibels (dBA). Typically, the human ear can barely perceive a change in noise level of 3 dBA. A change in 5 dBA is readily perceptible, and a change in 10 dBA is perceived as being twice or half as loud.

2.6. Sound Propagation
Sound is transmitted in air by pressure variations from its source to the surroundings. Sound levels will decrease as the distance between the source and the receptor increases. While absorption by air is one of the factors attributing to the weakening of a sound during transmission, distance plays a more important role in noise reduction during transmission. Depending on the source of the sound for every doubling of distance the level will be reduced between 3 and 6 dB.

The reduction of a sound is called attenuation.

Other factors for noise attenuation are ground absorption and shielding. Noise models use hard site (reflective surfaces) and soft site (absorptive surfaces) to help calculate predicted noise levels. Hard site conditions assume no excessive ground absorption between the noise source and the receptor. Soft site conditions such as grass, soft dirt or landscaping attenuate noise at a rate of an additional 1.5 dB per doubling of distance.

In order to break the line of sight, walls between a noise source and a receptor are often used for noise attenuation to reduce the noise levels at the receptor. Additional barriers such as buildings, hills and heavy vegetations can also reduce the noise levels. Typically, walls will reduce noise levels by 5-10dB. The higher the wall is, the higher the noise reduction will be.

2.7. Measurement of Sound
There are many ways to evaluate noise measured over periods of time. Equivalent continuous sound level (Leq) is the total sound energy measured over a stated period of time. LAs(Max) is the maximum level with A-weighted frequency response and slow time constant. The Community Noise Equivalent Level (CNEL) is the LAeq (equivalent noise level) over a 24-hour period with a penalty of 5dB for noises occurring from 7:00 p.m. to 10:00 p.m. and a penalty of 10dB for noises ITEM 11.1. ATTACHMENT 11

NV5.COM | 9
occurring from 10:00 p.m. to 7:00 a.m. The noise penalty is added to the noise events during the evening and nighttime hours when individuals are more sensitive to noise.

2.8. Ground-Borne Vibration
Vibration is periodic motion of a solid medium in alternately opposite directions from the position of equilibrium in which the motion’s amplitude can be described in terms of displacement, velocity, or acceleration. The peak particle velocity (PPV) or the root mean square (RMS) velocity is usually used to describe vibration amplitudes. The PPV is defined as the maximum instantaneous peak or negative peak of the vibration wave. The RMS is defined as the square root of the average of the squared amplitude of the signal. PPV is the most commonly used descriptor for evaluating potential building damage, whereas RMS is generally used to assess human response. Typically, ground-borne vibration, generated by man-made activities, attenuates rapidly with distance from the source of vibration. Man-made vibration issues are therefore usually confined to short distances (i.e., 500 feet or less) from the source. Tables 1 and 2 display the criteria established by Caltrans for the likelihood of structural damage and human response due to vibration.

Operation of construction equipment, maintenance operations, and traffic traveling on roadways can generate ground-borne vibration. However, if the roadway is smooth, the vibration from traffic is typically not perceptible.

Each of the noise limits specified in Table 4 shall be reduced by five dBA for impulsive or simple tone noises, or for noises consisting of speech or music.

If the ambient noise level exceeds that permitted by any of the first four noise-limit categories specified in Table 4, the allowable noise limit shall be increased in five dBA increments in each category to encompass the ambient noise level. If the ambient noise level exceeds the fifth noise level category, the maximum ambient noise level shall be the noise limit for that category.

Section 6.68.090 states that noise sources associated with construction, repair, remodeling, demolition, paving or grading of any real property, provided said activities do not take place between the hours of 8 p.m. and 6 a.m. on weekdays and Friday commencing at 8 p.m. through and including 7 a.m. on Saturday; Saturdays commencing at 8 p.m. through and including 7 a.m. on the next following Sunday and on each Sunday after the hour of 8 p.m. Provided, however, when an unforeseen or unavoidable condition occurs during a construction project and the nature of the project necessitates that work in process be continued until a specific phase is completed, the contractor or owner shall be allowed to continue work after 8 p.m. and to operate machinery and equipment necessary until completion of the specific work in progress can be brought to conclusion under conditions which will not jeopardize inspection acceptance or create undue financial hardships for the contractor or owner.

3.2. Sacramento County General Plan
The Noise Element of the Sacramento County General Plan provides a basis for comprehensive local policies to control and abate environmental noise and to protect the citizens of Sacramento County from excessive noise exposure.

Traffic and Railroad Noise Sources:

NO1. The noise level standards for noise-sensitive areas of new uses affected by traffic or railroad noise sources in Sacramento County are shown by Table 5. Where the noise level standards of Table 5 are predicted to be exceeded at new uses proposed within Sacramento County which are affected by traffic or railroad noise, appropriate noise mitigation measures shall be included in the project design to reduce projected noise levels to a state of compliance with the Table 5 standards.

Non-Transportation Noise Sources:

NO5. The interior and exterior noise level standards for noise-sensitive areas of new uses affected by existing non-transportation noise sources in Sacramento County are shown by Table 6. Where the noise level standards of Table 6 are predicted to be exceeded at a proposed noise-sensitive area due to existing non-transportation noise sources, appropriate noise mitigation measures shall be included in the project design to reduce projected noise levels to a state of compliance with the Table 6 standards within sensitive areas.

NO6. Where a project would consist of or include non-transportation noise sources, the noise generation of those sources shall be mitigated so as not exceed the interior and exterior noise level standards of Table 6 at existing noise-sensitive areas in the project vicinity.

ITEM 11.1. ATTACHMENT 11

NV5.COM | 12
NO7. The “last use there” shall be responsible for noise mitigation. However, if a noise generating use is proposed adjacent to lands zoned for uses which may have sensitivity to noise, then the noise generating use shall be responsible for mitigating its noise generation to a state of compliance with the Table 6 standards at the property line of the generating use in anticipation of the future neighboring development.

Construction Noise:

NO8. Noise associated with construction activities shall adhere to the County Code requirements. Specifically, Section 6.68.090(e) addresses construction noise within the County.

General Noise Policy:

NO12. All noise analyses prepared to determine compliance with the noise level standards contained within this Noise Element shall be prepared in accordance with Table 7.

NO13. Where noise mitigation measures are required to satisfy the noise level standards of this Noise Element, emphasis shall be placed on the use of setbacks and site design to the extent feasible, prior to consideration of the use of noise barriers.

NO14. Noise analyses prepared for multi-family residential projects, town homes, mixed use, condominiums, or other residential projects where floor ceiling assemblies or party-walls shall be common to different owners/occupants, shall be consistent with the State of California Noise Insulation standards.

NO15. The County shall have the flexibility to consider the application of 5 dB less restrictive exterior noise standards than those prescribed in Tables 5 and 6 in cases where it is impractical or infeasible to reduce exterior noise levels within infill projects to a state of compliance with the Table 5 or 6 standards. In such cases, the rational for such consideration shall be clearly presented and disclosure statements and noise easements should be included as conditions of project approval. The interior noise level standards of Tables 5 and 6 would still apply. The maximum allowable long-term noise exposure permissible for non-industrial uses is 75 dB.

3.3. City of Rancho Cordova Municipal Codes
The site is under the jurisdiction of the City of Rancho Cordova. Per Chapter 23.737 of the Rancho Cordova Municipal Code (RCMC), all permanent and temporary land uses must comply with noise performance standards set forth in Chapter 6.68 to minimize various potential operational impacts. Section 6.68.010A states “excessive, unnecessary or offensive noise within the city is detrimental to the public health, safety, welfare and the peace and quiet of the inhabitants of the city and therefore is declared a public nuisance.” Section 6.68.070A states the exterior noise standards applicable to all properties as follows:

Table 8 – City of Rancho Cordova Exterior Noise Standards Time Period Exterior Noise Standard
7:00 a.m. – 10:00 p.m. 55 dBA
10:00 p.m. – 7:00 a.m. 50 dBA
RCMC 6.68.070B also states that it is unlawful for any person at any location within the city to create any noise which causes the noise levels on an affected property, when measured in the designated noise area, to exceed for the duration of time set forth following, the specified exterior noise standards in any one hour by:

NV5.COM | 16
RCMC 6.68.110 states that it is unlawful for any person to create any noise which causes the noise level at any school, hospital or church, while the same is in use, to exceed the noise standards or to create any noise which unreasonably interferes with the use of such institution or unreasonably disturbs or annoys patients in the hospital. In any disputed case, interfering noise which is 10 dBA or more greater than the ambient noise level at the building shall be deemed excessive and unlawful.

Any violation of the RCMC noise ordinances is unlawful and constitutes a public nuisance. If the Rancho Cordova chief of police or the city health officer have reason to believe there has been a violation, a written notice will be served to the alleged violator. The notice will include dBA readings, time and place of the readings, and may include an order that a corrective action be taken within a specified time. If corrective action is not taken within the specified time, the violation will constitute an infraction. Each day of violation is considered a new and separate offense.

Public nuisances are covered in Chapter 16.18 of the RCMC. Per Section 16.18.205(F)(4) the maximum amount of the fine imposed for each code violation under this section is as follows:
i. $100 per day for a first violation;
ii. $200 per day for a second violation of the same ordinance within one year; and iii. $500 per day for each additional violation of the same ordinance within one year.

RCMC 6.68.070D states that “if the ambient noise level exceeds that permitted by any of the first four noise -limit categories specified in subsection (B) of this section, the allowable noise limit shall be increased in 5 dBA increments in each category to encompass the ambient noise level. If the ambient noise level exceeds the fifth noise level category, the maximum ambient noise level shall be the noise limit for that category.”

1. Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving land use. Where it is not practical to mitigate exterior noise levels at patio or balconies of apartment complexes, a common area such as a pool or recreation area may be designated as the outdoor activity area.

2. As determined for a typical worst-case hour during periods of use.

3. Where it is not possible to reduce noise in outdoor activity areas to 60 dB Ldn/CNEL or less using a practical application of the best-available noise reduction measures, an exterior noise level of up to 65 dB Ldn/CNEL may be allowed provided that available exterior noise level reduction measures have been implemented and interior noise levels are in compliance with this table.

4. In the case of hotel/motel facilities or other transient lodging, outdoor activity areas such as pool areas may not be included in the project design. In these cases, only the interior noise level criterion will apply.

5. The intent of this noise standard is to provide increased protection against sleep disturbance for residences located near railroad tracks.

Note: The City’s General Plan noise limits are defined in dB. However, dBA is the more common unit of measurement for noise because it reflects the normal hearing sensitivity range of the human ear. We therefore advise that noise significance threshold be in dBA.

3.5. Rio del Oro Specific Plan’s (RDOSP) EIR
The proposed site is located within the Plan Area of Rio Del Oro. A background noise study was performed in 2004 and 2005 as part of the Environmental Impact Report (EIR) for the RDOSP.

The following provides a list of proposed measures in the EIR. Note: Each measure is consistent (in scope and numbering) with the mitigation measures listed in the RDOSP Project EIR.

Mitigation Measure 3.16-1: Implement Measures to Prevent Exposure of Sensitive Receptors to Temporary Construction-Generated Noise.

To reduce impacts associated with noise generated during construction activities, the project applicant(s) for all project phases shall conform to the following requirements:
 Noise-generating construction operations shall be limited to the hours between 7 a.m. and 7 p.m. Monday through Friday, and between 8 a.m. and 6 p.m. on Saturday and Sunday.
 All construction equipment and equipment staging areas shall be located as far as possible from nearby noise-sensitive land uses.
 All construction equipment shall be properly maintained and equipped with noisereduction intake and exhaust mufflers and engine shrouds, in accordance with manufacturers’ recommendations. Equipment engine shrouds shall be closed during equipment operation.
 All motorized construction equipment shall be shut down when not in use to prevent idling.
 The following measures shall be required for exterior activities that involve the use of heavy-duty construction equipment (see Table 12) located within 800 feet of occupied noise-sensitive daytime land uses (e.g., school classrooms, childcare and convalescent care facilities, inpatient medical facilities, places of worship):
o Individual operations and techniques shall be replaced with quieter procedures (e.g., using welding instead of riveting, mixing concrete off-site instead of onsite). o Written notification of construction activities shall be provided to all noisesensitive receptors located within 800 feet of construction activities. Notification shall include anticipated dates and hours during which construction activities are anticipated to occur and contact information, including a daytime telephone number, for the project representative to be contacted in the event that noise levels are deemed excessive. Recommendations to assist noise-sensitive land uses in reducing interior noise levels (e.g., closing windows and doors) shall also be included in the notification.
o To the extent feasible, acoustic barriers (e.g., lead curtains, sound barriers) shall be constructed to reduce construction-generated noise levels at affected noise sensitive land uses. The barriers shall be designed to obstruct the line of sight between the noise-sensitive land use and on-site construction equipment. When installed properly, acoustic barriers can reduce construction noise levels by approximately 8–10 dBA (EPA 1971).

Mitigation Measure 3.16-2: Implement Measures to Reduce Potential Exposure of Sensitive Receptors to Stationary Source–Generated Noise.

To reduce potential long-term exposure of sensitive receptors to noise generated by Citycontrolled, project-related stationary noise sources from private activities, the City shall evaluate individual facilities, subdivisions, and other project elements for compliance with the City Noise Ordinance and policies contained in the City General Plan. All project elements shall comply with City noise standards. The project applicant(s) for all project phases shall implement the following measures to assure maximum reduction of project interior and exterior noise levels from operational activities:
 The proposed land uses shall be designed so that on-site mechanical equipment (e.g., HVAC units, compressors, generators) and area-source operations (e.g., loading docks, parking lots, and recreational-use areas) are located as far as possible from or shielded from nearby noise-sensitive land uses.
 To the extent feasible, residential land uses located within 2,500 feet and within the direct line of sight of major noise-generating commercial and industrial land uses (e.g., loading docks, manufacturing facilities, equipment/vehicle storage and repair facilities, and material processing areas such as concrete batch plants) shall be shielded from the line of sight of these facilities by construction of a sound barrier. To be effective, fences ITEM 11.1. ATTACHMENT 11

NV5.COM | 21
or sound barriers need to be continuous or solid, with very few gaps, and must block the line of sight to windows of neighboring dwellings. Achieved noise reductions from fences or barriers can vary, but typically range from approximately 5 to 10 dBA, depending on construction characteristics, height, and location. The developer shall obtain the services of a professional acoustician to determine the design and location of noise barriers to be constructed.

Mitigation Measure 3.16-5: Implement Measures to Improve Land Use Compatibility with Noise Sources.

To meet City noise standards set forth in the City General Plan and Noise Ordinance and improve compatibility between project land uses and noise sources, the project applicant(s) for all project phases shall implement the following for all project phases:
 Implement Mitigation Measure 3.16-2 described above.
 Obtain the services of a consultant (such as a licensed engineer or licensed architect) to develop noise attenuation measures for the proposed construction of onsite noisesensitive land uses (i.e., residential dwellings and school classrooms) that will produce a minimum composite Sound Transmission Class (STC) rating for buildings of 30 or greater, individually computed for the walls and the floor/ceiling construction of buildings, for the proposed construction of on-site noise-sensitive land uses (i.e., residential dwellings and school classrooms).
 When tentative subdivision maps and commercial uses are proposed, the project applicant(s) shall conduct a site-specific acoustical analysis to determine predicted roadway noise impacts attributable to the project, taking into account site-specific conditions (e.g., site design, location of structures, building characteristics). The acoustical analysis shall evaluate stationary- and mobile-source noise attributable to the proposed use or uses and impacts on nearby noise-sensitive land uses, in accordance with adopted City noise standards. Feasible measures shall be identified to reduce project-related noise impacts. Measures may include, but are not limited to, the following:
o construction of exterior sound walls;
o use of increased noise-attenuation measures in building construction (e.g., dualpane, sound-rated windows; exterior wall insulation); and o limiting noise-generating operational activities associated with proposed commercial land uses, including truck deliveries.

3.6. Ground Borne Vibration Standards
The City of Rancho Cordova and the Sacramento County do not have quantitative standards relative to ground-borne vibration. The Rancho Cordova Municipal Code (Section 23.737.050, Vibration Standards), states that uses that generate vibrations that may be considered a nuisance or hazard on any adjacent property shall be cushioned or isolated to prevent generation of vibrations. Uses shall be operated in compliance with the following provisions:

A. Uses shall not generate ground vibration that is perceptible without instruments by the average person at any point along or beyond the property line of the parcel containing the activities.

B. Uses, activities, and processes shall not generate vibrations that cause discomfort or annoyance to reasonable persons of normal sensitivity or which endanger the comfort, repose, health, or peace of residents whose properties about the property lines of the subject parcel.

C. Uses shall not generate ground vibration that interferes with the operations of equipment and facilities of adjoining parcels.

D. Vibrations from temporary construction/demolition and vehicles that leave the subject parcel (e.g., trucks, trains, and aircraft) are exempt from the provisions of this section.

Caltrans has a guidance manual (“Transportation- and Construction-Induced Vibration Guidance Manual” updated April 2020) that provides thresholds for potential impacts on human comfort and damage to buildings that will be used to assess impacts due to ground-borne ITEM 11.1. ATTACHMENT 11

NV5.COM | 23
vibration. In most circumstances, common ground-borne vibrations related to roadway traffic and construction activities pose no threat to buildings or structures.

3.7. Significance Thresholds
For the purpose of this study the following threshold of significance will be used to determine the noise and vibration impact on the nearest sensitive receptors:

Construction Noise
 Construction activities between the hours of 7:00 a.m. to 6:00 p.m. on weekdays and 9:00 a.m. to 6:00 p.m. on weekends, which is within the allowable construction hours set by the City of Rancho Cordova and also within the hours referenced in the EIR (MM 3.16-1).  The City of Rancho Cordova Municipal Code and the Sacramento County General Plan do not have a maximum numeric limit for noise levels related to construction activities at the sensitive receptors. However, the City of Rancho Cordova General Plan mentions that construction activities are exempt from noise standards, provided they take place between 7:00 a.m. to 6:00 p.m., Monday through Saturday, and 9:00 a.m. to 6:00 p.m. on Sunday.

The City of Rancho Cordova General Plan also states that construction activities generate maximum noise levels typically range from 85 dBA to 90 dBA at a distance of 50 feet. The Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment provides an eight-hour construction noise level threshold of 80 dBA Leq during daytime at residential (noise-sensitive) uses, and 85 dBA during the daytime at commercial uses.

Therefore, those thresholds were used to evaluate the need of mitigation measures during construction activities.

Construction Vibration
 0.04 PPV at a residential receptor.

On-Site Operational Noise
 Long-term stationary-source noise levels that would exceed applicable City noise standards (Tables 8, 9, and 10)

4. Environmental Settings
Ambient Noise or background levels are the all-encompassing noises associated with a given environment at a specific time, usually a composite of sound from many sources from many directions, near and far without any particular dominant sound. The primary existing noise sources surrounding the project site are traffic flow along Luyung Drive, White Rock Road, and Sunrise Boulevard. Other noise sources include traffic noise from other roads surrounding the project site and noise from other industrial and commercial properties located west of the site.

The land located north, south, and east of the project site is not yet developed, and as such the current ambient noise levels are lower than the anticipated future ambient noise levels. Once the area is developed, the noise produced from nearby roads that are planned to be built will ITEM 11.1. ATTACHMENT 11

NV5.COM | 24
contribute to the ambient noise levels. Noise from other industrial and commercial facilities that will be built in the area will also increase ambient levels.

Therefore, in order to be conservative, NV5 used the daytime and nighttime noise limits from the Rancho Cordova General Plan (55 dBA for daytime and 45 dBA for nighttime) as the ambient noise levels for the area. Using the City’s noise limits is expected to represent the worst-case scenario as the ambient noise is expected to increase once roads and industrial and commercial facilities are constructed.

5. Environmental Impacts

5.1. Thresholds of Significance
According to the current CEQA Appendix G guidelines, noise impacts are considered potentially significant if they cause:

A. Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies.

Noise levels exceeding the City of Rancho Cordova Noise Standards would be considered significant.

B. Exposure of persons to or generation of excessive ground-borne vibration or groundborne noise levels.

C. A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project.

D. A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project.

E. For a project within an airport land use plan or where such a plan has not been adopted, within two miles of a public airport or public use airport, expose people residing or working in the project area to excessive noise levels.

F. For a project within the vicinity of a private airstrip, expose people residing or working in the project area to excessive noise levels.

5.2. Impact Analysis
A. Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies.

Project Operational Noise
The potential for a substantial permanent increase in noise levels was assessed for mobile and stationary sources.

ITEM 11.1. ATTACHMENT 11

NV5.COM | 25
Operational On-site Stationary Noise
The City of Rancho Cordova’s general plan states that the maximum allowable noise level (defined as hourly Leq) for stationary noise sources is 55 dB during the daytime (7 a.m. – 10 p.m.) and 45 dB during the nighttime (10 p.m. – 7 a.m.). The noise limits are defined in dB in the City document. However, dBA is the more common unit of measurement for noise because it reflects the normal hearing sensitivity range of the human ear. We therefore advise that noise significance threshold be in dBA.

The potential noise impacts on the community would be associated with stationary sources operating on the project site. Motor vehicle noise on public streets is often considered as part of the ambient noise; when vehicles enter a private site, they are considered as part of the site’s noise sources. The trucks and employee cars activities on site could affect the closest sensitive receptors.

The impact evaluation of the project was performed using SoundPlan Essential 5.1, an environmental noise propagation computer program that was developed to assist with noise propagation calculations for major noise sources and projects. The program calculates the sound pressure level at a location utilizing the sound emission properties of the source(s) and environmental propagation factors (sound spreading due to distance, ground affects, barriers, topography, as well as atmospheric attenuation). The program also includes a number of standardized methodologies that can be utilized to quantify the acoustic effect of these environmental factors. The specific standard employed by this program is that described in the ISO standard 9613 “Acoustics - Attenuation of sound during propagation outdoors”. The modeled ambient temperature was 10 degrees C (50 degrees F) and the assumed relative humidity (RH) was 70 percent. The ground absorption value utilized in the model was 0 (for hard ground), which is conservatively representative of the land at the site.

Elevation lines were created using the grading plan. No sound attenuation due to foliage was included in this analysis. A 12-foot concrete sound wall on the north of the site was also included as part of the current concept plan for the site.

This study evaluates the acoustical impact of the proposed facility on the adjacent future sensitive receptors and compares it to the local noise standards to assess if any mitigation measure would be necessary to reduce the noise exposure to the community. Future community noise impacts from the onsite operations were modeled using SoundPlan Essentials

5.1 acoustical modeling software. This study focuses on the daytime and nighttime noise levels in order to determine the acoustical impact of the site on the closest receptors.

Noise Sources
Vehicles Noise Sources
Based on the traffic count provided (Appendix C), the following are the noise sources related to vehicles driving on site:

Daytime (7 a.m. - 10 p.m.):
- Eight hundred and forty-one (841) cars will enter the site and nine hundred and two (902) will leave the site between the hours of 7 a.m. and 10 p.m.
- One hundred and thirty-one (131) line haul trucks will be entering and one hundred and thirtythree (133) leaving the site between the hours of 7 a.m. and 10 p.m.

Nighttime (10 p.m. – 7 a.m.):
- Six hundred and twenty-two (622) cars will be entering and five hundred and sixty-three (563) will be leaving the site between the hours of 10 p.m. and 7 a.m. - One hundred and seventy (170) line haul trucks will be entering and leaving the site between the hours of 10 p.m. and 7 a.m.

Noise sources were entered in the system as octave band sound power levels based on reference noise levels measured at a similar facility. NV5 took sound pressure level measurements with a reference distance of 50 feet in order to represent the noise levels associated with the different noise sources. The measurements included sound pressure levels of one truck driving and parking at the loading docks. This data is used to represent the noise levels associated with a single truck entering the site or being active at the loading dock.

Trucks
Three area sources were placed along the north, south, and west of the proposed building site to represent the truck activities (line haul) at the loading docks and trailer storage.

One line source was placed between the truck entrance and the loading docks to model the noise from trucks queuing and two line sources were placed between the truck loading docks and driveways to model noise from trucks driving on site (i.e. path in and path out).

Each truck will be operating for up to 5 minutes at each area.

Truck activity is expected during the day and at nighttime, therefore, trucks were modeled to be active during the day and at nighttime. Using the maximum hourly count, the maximum amount of time that trucks will be active onsite were calculated. As such, the trucks were modeled to be operating for a total of 20 minutes per hour during the day and 35 minutes per hour at nighttime in each area source and line source.

ITEM 11.1. ATTACHMENT 11

NV5.COM | 27
Employee Parking and Trailer Storage
The employee parking was represented by a parking area in the eastern portion of the property.

Trailer storage was represented by a parking area in the western portion of the property. Due to close proximity of the trailer storage north and south of the site to the north and south loading docks, they were included in the area sources mentioned in the previous section. The noises associated with parking of vehicles that are accounted for in the model include engine ignition, vehicle doors opening and closing. The traffic volume of the parking lot is entered with the number of moves per parking bay (in and out are each considered a single move), the hour (for the time slices day and night) and the number of parking bays.

The model predicted the maximum noise levels produced by the truck and employee car activities using expected noise sources from trucks and employee cars. The sources were modeled as operating at the same time to represent the worst-case scenario.

Tables 13 and 14 list the sources that were considered in the analyses and Exhibit D shows the locations of noise sources and the proposed building.

As mentioned above, currently the areas north, south, and east of the site are undeveloped, and as such the closest sensitive receptors used in this study are based on the proposed developments specified in the Rio Del Oro Specific Plan. Sensitive receptors within the vicinity of the proposed site that may be affected are residential areas north and south of the site and a school campus area south of the site.

A total of eight (8) receptors were modeled to evaluate the proposed project’s operational noise impact. The location of the sensitive receptors is shown in Exhibit D, represented by a yellow dot.

Receptors 1 through 5 represent the single-family residential zone that will be located north of the site and north of greenbelt and International Drive. Receptors 6 and 7 represent the single-family and medium density residential zones, respectively, that will be located south of the site. Receptor 8 represents the school campus zone that will be located south of the site. All receptors are twostories high.

Exhibit D shows the predicted noise level map at the sensitive receptor areas. Exhibits E and F show the estimated noise level contours for the project for the daytime and nighttime, respectively.

Operational noise levels (hourly Leq) are anticipated to range between 39.3-46.0 dBA during the daytime and 40.3-47.9 dBA at nighttime at the nearest sensitive receptors. As part of the development of the Rio del Oro business park, the vacant land south of the site that is in between the site and the south sensitive receptors will be developed and buildings will be built. Additionally, the City requires that any industrial facility that is located within 2,500 feet and within the direct line of sight of a residential land use area to have a sound barrier to help protect and shield sensitive receptors from unwanted noise (see MM 3.16-2). As such, the predicted noise levels for the south receptors will be reduced by a minimum of 15 dBA once the vacant land is developed. The maximum number of trucks and cars at any hour (i.e. peak hour) was used to calculate the predicted noise levels. Therefore, the predicted noise levels of 45.5 dBA for the north receptors represent the noise levels for when the maximum number of trucks and cars are active at the same time. However, based on the Trip Generation Count (Appendix C) the peak hour for trucks is not the peak hour for cars and the car activities will actually be at a minimum. Similarly, during the peak hour for cars, the truck activities will be at a minimum. Therefore, it is unlikely that the predicted noise levels for the north receptors exceed the City limit of 45 dBA. Table 15 shows the results of the noise level predictions.

1) Predicted noise levels represent the noise levels for the peak hours when the maximum number of trucks and cars are active at the same time. However, during the peak hour for trucks, the car activities will be at a minimum and during the peak hour for cars, the truck activities will be at a minimum. Therefore, the predicted daytime and nighttime noise levels for Receptors 1-5 are not expected to exceed the limits set forth by the City. 2) Predicted noise levels for Receptors 6-8 will be attenuated by the buildings and sound barriers that are going to be built as part of the business park development. Therefore, the predicted daytime and nighttime noise levels for Receptors 6-8 are not expected to exceed the limits set forth by the City.

The City of Rancho Cordova has established noise standards relevant to operational activities associated with the proposed site. For this analysis, the numerical standard from the City of Rancho Cordova General Plan was used in order to evaluate the acoustical impact of the site on the nearest sensitive receptors. The City of Rancho Cordova General Plan has a maximum noise level of 55 dBA during the daytime and 45 dBA at nighttime as hourly Leq for new projects affected by or including non-transportation sources (see Table 10). However, The City may impose noise level standards which are more or less restrictive than those specified above based upon determination of existing low or high ambient noise levels.

For the purpose of this study, the noise limits stated in the General Plan (55 dBA for daytime and 45 dBA for nighttime) were used as the ambient noise levels. Predicted noise levels are anticipated to range between 39.3 and 46.0 dBA during the daytime, and between 40.3 and

47.9 dBA at nighttime at the nearest sensitive receptors without any sound attenuation.

However, as explained above, once the vacant land on the south is developed, the predicted noise levels for the south receptors would be reduced by a minimum of 15 dBA. Additionally, because the model calculates the predicted noise levels as if the maximum number of trucks and cars are all active at the same time, the predicted noise levels represent the worst-case scenario, which is unlikely to happen as the peak hour for trucks is not expected to be the peak hour for cars and vice versa. Therefore, the predicted noise levels for the north receptors are not expected to exceed the daytime or nighttime noise limits. Thus, the predicted daytime and nighttime noise levels for all sensitive receptors near the site will be within the limits set forth by the City.

Backup alarms can be a cause of disturbance. Trucks at the Project site would also utilize backup alarms during loading/unloading activities and parking. Backup alarms produce a typical noise level of 97 dBA at 3.28 feet. Based on distance attenuation, at 625 feet (distance from the closest residence north of the site to the north trailer storage), backup alarms noise levels would be approximately 51.4 dBA without any sound attenuation. The proposed sound wall will provide a minimum of 5-10 dBA sound attenuation.

The backup alarms noise levels would be approximately 45.3 dBA at 1,260 feet, where the closest residence south of the site is located relative to the south trailer storage. As discussed above, the Rio Del Oro Specific Plan proposes that buildings will be constructed south of the site and a sound barrier will be installed between any industrial facility that is located within 2,500 feet and within the direct line of sight of a residential land use area. With these in place, the south sensitive receptors will be shielded from the noise and the predicted noise level will be within the noise standards set by the City.

Based on this noise analysis of the operational on-site stationary noise, the acoustical impact of the stationary noise for the proposed project would be less than significant.

B. Exposure of persons to or generation of excessive ground-borne vibration or groundborne noise levels.

Ground-borne Vibration
Ground-borne Vibration During Construction
This section focuses on the assessment of potential impacts associated with construction‐ generated vibration. As mentioned above, the site is currently located on undeveloped land.

Future developments and land usage have been proposed according to the Rio Del Oro Specific Plan. If the proposed residential neighborhoods and school are constructed before the construction of the proposed Receiving Center starts, the nearest sensitive receptors may be impacted.

Neither the City of Rancho Cordova nor the County of Sacramento have adopted significance thresholds for vibration. Vibration may be expressed through a number of parameters that describe the displacement, the vibration velocity, or acceleration experienced by an object. In ambient applications, a root-mean square vibration velocity of 0.04 inches per second is often taken as a possible nuisance level (Caltrans 2020). Project construction vibration levels using the following vibration assessment methods defined by Caltrans. To describe the human response (annoyance) associated with vibration impacts Caltrans provides the following equation:

PPVequip = PPVref x (25/D)1.5
The primary source of vibration during construction would be from the operation of a vibratory roller. As referenced in the Transit Noise and Vibration Impact Assessment (Federal Transit Administration 2018), a vibratory roller would create a vibration level of 0.21 inch per second PPV at 25 feet. Construction equipment are anticipated to be at a minimum distance of 220 feet from the closest sensitive receptor. At 220 feet, where the nearest sensitive receptor would be located, a vibratory roller would create vibration level of 0.008 in/sec, which would be below the nuisance threshold. Other construction equipment expected to be used as part of this project has lower vibration levels and therefore, will not be a nuisance.

Therefore, vibration impacts will be less than significant.

Ground-borne Vibration During Operations
The project is not expected to be operating heavy-duty industrial equipment during the operations phase. Trucks and cars are not expected to generate any perceptible vibration levels outside of the right-of-way. There are no operational sources of vibration that would generate vibration levels that exceed 0.04 in/sec. Therefore, the proposed project would result in a less than significant impact related to operational vibration.

C. A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project.

Permanent Noise Impact Analysis
Traffic Source Permanent Noise Impact
The proposed site is located within the Plan Area of Rio Del Oro. Per the EIR of the Plan Area of Rio Del Oro, because future growth is expected to surround the Rio del Oro with trafficgenerating development by 2030, resulting in greater areawide and on-site noise levels, full buildout of development on the Rio Del Oro itself would not contribute to noticeable (i.e., 3 dBA or greater) increases in ambient noise levels at noise-sensitive land uses that exceed land use compatibility noise criteria. This direct impact is considered less than significant. No indirect impacts would occur. Therefore, no mitigation is required.

Stationary Source Permanent Noise Impact
As described above in the impact assessment for criteria A, increases in noise levels related to stationary noise sources for the proposed project would not substantially elevate the existing ambient noise environment as the predicted noise levels for all receivers expected to be below the ambient noise levels. The noise level increase is expected to be below 3 dB and therefore, would be less than significant in the vicinity of the site.

D. A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project.

Temporary Noise Impact from Construction
The City of Rancho Cordova does not have established maximum allowable noise levels, but the City’s municipal code defines the following hours during which construction activities across the street or right away from a residential area are permitted: 6 a.m. and 8 p.m. Monday through Friday, or between 7 a.m. and 8 p.m. on Saturday and Sunday. The City’s General Plan and RDOSP EIR define the construction hours as 7 a.m. and 7 p.m. Monday through Friday, or between 8 a.m. and 6 p.m. on Saturday and Sunday. Construction of the proposed project is expected to take approximately 12 months to complete. Construction is expected to occur from June 2022 through June 2023, during permissible hours.

The site is currently located on undeveloped land. Future developments and land usage have been proposed according to the Rio Del Oro Specific Plan. If the proposed residential neighborhoods and school are constructed before the construction of the proposed Receiving Center starts, the nearest sensitive receptors may be impacted. Noise impacts form the construction activities were evaluated by estimating the typical noise levels for each type of construction equipment using the Federal Highway Administration (FHWA) roadway construction model (RCNM) and comparing the Leq at the nearest sensitive receptors (Loc 1 ITEM 11.1. ATTACHMENT 11

NV5.COM | 36
through Loc 8) with the acceptable noise standards. Construction of the project would be done in four phases: grading, building construction, paving, and architectural coating. Typical construction equipment described below will be used for the project. Table 17 lists the equipment expected to be used during the construction phase.

Estimated usage was estimated for each expected equipment from the construction activities as shown in Table 16. Each type of construction equipment produces maximum noise levels (Lmax) at a reference distance of 50 feet from the noise source.

Noise levels generated by construction equipment (or by any point source) decrease at a rate of approximately 6 dB per doubling of distance from the source. There are seven residential areas and a school campus area within the vicinity of the site:
 Locations 1 through 4 represent the single-family residential zone (ranging from approximately 220 feet to 655 feet north from the site)  Location 5 represents the medium density residential zone (approximately 1,135 feet north from the site)
 Location 6 represents the single-family residential zone (approximately 980 feet south from the site)
 Location 7 represents the medium density residential zone (approximately 975 feet south from the site)

 Location 8 represents the school campus zone (approximately 825 feet south from the site)
The following map, Exhibit G, shows the location of the nearest sensitive receptors and their distances to the site.

Using the RCNM, the noise levels were calculated for each receptor from the construction equipment, as presented in Table 17.

As described in Table 17, the highest predicted noise level from construction activities is 72.5 dBA measured at the Location 1 SF Home Site during the grading phase. The City does not provide any noise level limits for construction noise levels. The noise levels are expected to be below the 80 dBA threshold from the Federal Transit Administration (FTA).

Therefore, construction noise impacts are expected to be less than significant during all construction phases.

E. For a project within an airport land use plan or where such a plan has not been adopted, within two miles of a public airport or public use airport, expose people residing or working in the project area to excessive noise levels.

Mather Airport is approximately 1.8 miles southwest of the site. The project site is an industrial site with truck activities. The employees are expected to work inside the industrial building and in the yard assisting with trucks. The activity at the project site is not expected to be noise sensitive and therefore, no impact would occur, and no mitigation measures are necessary.

F. For a project within the vicinity of a private airstrip, expose people residing or working in the project area to excessive noise levels.

The project site is not within 2 miles of a private airstrip or heliport. Therefore, no impact would occur, and no mitigation measures are required.

6. Mitigation Measure
No mitigation measures are required for this project.
