CHAPTER 1

PURPOSE AND BACKGROUND

The City of Pasadena (City) has prepared this Addendum to the 2015 Pasadena General Plan Environmental Impact Report (GP EIR) (State Clearinghouse No. 2013091009) to address the potential site-specific environmental impacts associated with the update to the North Lake Specific Plan (proposed project or project). This Addendum is prepared in accordance with the California Environmental Quality Act of 1970 (CEQA) (Cal. Public Resources Code Section 21000, et. seq., as amended) and its implementing guidelines (Cal. Code Regs., Title 14, Section 15000 et. seq., 2016). This Addendum has been prepared and will be processed consistent with CEQA Guidelines (Cal. Code Regs., Title 14, Section 15162 and Section 15164).

In 2015, the City updated the Pasadena General Plan and prepared t he GP EIR to analyze potential citywide impacts, broad policy alternatives, and programmatic mitigation measures associated with the update of the Pasadena General Plan and specific plan amendments , which updated development caps within each specific plan area. The changes focused on the Land Use and Mobility Elements and the Land Use Diagram. The update also included the consolidation of optional elements into required elements of the General Plan. The Land Use and Mobility Elements, together with the other General Plan elements, guide the overall physical development of the City through horizon year 2035. The GP EIR is a Program EIR as defined by CEQA Guidelines Section 15161, California Cod e of Regulations, Title 14, Division 6, Chapter 3 and prepared in compliance with CEQA Guidelines Section 15168. The Final GP EIR was certified and the findings, Statement of Overriding Considerations (SOC), and Mitigation Monitoring and Reporting Program (MMRP) adopted by the City Council on August 17, 2015 (Resolution No. 9451).

Following the adoption of the General Plan Update and certification of the GP EIR, future discretionary actions include specific plan updates and amendments and zone changes to provide consistency with the General Plan. Therefore, the City is updating seve n existing specific plans and creating one new specific plan to align with and implement the updated General Plan. The specific plan updates focus on establishing neighborhood-specific design and land -use goals resulting in new development standards and gu idelines that will help shape the City’s major commercial and mixed -use areas. The North Lake Specific Plan (NLSP) is one of the seven existing specific plans to be updated as part of the General Plan Implementation Program.

Per the GP EIR, future discretionary review may rely on analysis provided in the GP EIR for the purpose of tiering and/or streamlining. The purpose of tiering is to use the analysis of general matters contained in a broader EIR (such as the GP EIR) with later CEQA documents on narrower or more site specific projects (CEQA Guidelines Section 15152). Tiering serves to reduce repetitive analysis and provide subsequent site specific analysis at a time when it is meaningful. Tiering is common and appropriate whe n the sequence of analysis is from a General Plan EIR to a program of lesser scope, such as a specific plan (CEQA Guidelines Section 15152[b]). Therefore, CEQA review required for the City’s eight specific plan areas may tier from the GP EIR pursuant to CEQA Guidelines Section 15152.

Chapter 1: Purpose and Background North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

1.1 Applicability and Use of an Addendum
Per the GP EIR, CEQA review required for the City’s specific plan areas may tier from the GP EIR pursuant to CEQA Guidelines Section 15152. In addition, per CEQA Guidelines Section 15152(h), other methods to streamline the environmental review process also exist. These methods include the use of a Program EIR (i.e., GP EIR) for later activities (CEQA Guidelines Section 15168) and preparing an addendum (CEQA Guidelines Section 15164). Lead agencies have discretion regarding which method may apply and should be used.

Under the process described in CEQA Guidelines Section 15168(c), later activities in the program must be examined in the light of the Program EIR to determine whether an additional environmental document must be prepared. No additional documentation is req uired for subsequent proposed actions (e.g., updating of the City’s specific plans to implement the General Plan) if the examination determines that the potential impacts were within the scope of the GP EIR, and subsequent proposed actions implement approp riate feasible mitigation measures identified in the MMRP that accompanies the Final EIR. Whether a later activity is within the scope of a Program EIR is a factual question that the lead agency determines based on substantial evidence in the record. Factors that a lead agency may consider in making that determination include, but are not limited to, consistency of the later activity with the type of allowable land use, overall planned density and building intensity, geographic area analyzed for environmental impacts and covered infrastructure as described in the Program EIR. If the agency finds that pursuant to CEQA Guidelines Section 15162, no subsequent EIR would be required, the agency can approve the activity as being within the scope of the project covered by the program EIR, and no new environmental document would be required.

The conditions in CEQA Guidelines Section 15162 calling for the preparation of a subsequent EIR are:

1. Substantial changes are proposed in the project which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects;

2. Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; or

3. New information of substantial importance which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the negative declaration was adopted, shows any of the following:
a. The project will have one or more significant effects not discussed in the previous EIR or negative declaration;
b. Significant effects previously examined will be substantially more severe than shown in the previous EIR;
c. Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant Chapter 1: Purpose and Background North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 1 ends

effects of the project, but the project proponents decline to adopt the mitigation measures or alternative; or
d. Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative.

Pursuant to CEQA Guidelines Section 15164, the City, as the lead agency, has prepared this Addendum to confirm that none of the conditions identified in CEQA Guidelines Section 15162 and Public Resources Code Section 21166(c) have been triggered. For a proposed modified project or implementing activity, CEQA Guidelines Section 15164 provides that an Addendum to a previously certified Final EIR may be prepared if only minor technical changes or additions are necessary, or none of the conditions described in Section 15162 calling for the preparation of a subsequent EIR or negative declaration have occurred. The City must consider the whole of the data presented in the GP EIR with the information provided in this Addendum and the previously adopted MMRP.

1.2 Format of This Addendum
The previously certified GP EIR serves as the primary environmental compliance document for the project, and this Addendum provides minor changes and additions to the GP EIR. This Addendum should be considered with the full text of the previously certified 2015 GP EIR. All applicable mitigation measures from the GP EIR would be applicable to the proposed project and, therefore, are incorporated by reference into this Addendum. This Addendum relies on the use of an Environmental Checklist Form (Checklist), as suggested in Section 15063(d)(3) of the CEQA Guidelines. Per the CEQA Guidelines, an addendum does not need to be circulated for public review but can be included in or attached to the Final EIR prior to making a decision on the project.

1.3 Summary of Findings
Based upon the Checklist prepared for the proposed project and supporting responses (see Chapter 3), adoption of the update to the NLSP would not result in substantial changes requiring major revisions to the previously certified GP EIR. Further, the proposed project would not result in any new significant environmental impacts that were not discussed in the GP EIR or a substantial increase in the severity of previously identified significant impacts. No new mitigation measures are required for the proposed project. Since only minor changes and additions are required to the GP EIR, and none of the conditions described in Public Resources Code Section 21166 or CEQA Guidelines Section 15162(a -b) or Section 15163 requiring preparation of a subsequent or supplemental EIR have occurred, the City finds that the preparation of an addendum to the GP EIR is the appropriate CEQA documentation for the proposed project and that the proposed project is within the scope of the GP EIR.

1.4 Lead Agency and Discretionary Approvals
This Addendum and the previously certified GP EIR are intended to serve as the environmental documentation for the changes being proposed under the NLSP Update. The City of Pasadena is the lead agency under CEQA and maintains authority to approve the Chapter 1: Purpose and Background North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Addendum for the adoption of the NLSP Update. Discretionary approvals being sought as part of the NLSP Update include the following:
• Acknowledgement of this Addendum to the GP EIR and that no subsequent CEQA document is required;
• General Plan Land Use Map amendment to update the land use categories depicted on the Land Use Diagram as proposed in the NLSP Update. This amendment would also update the Land Use Diagram to reflect the recommended NLSP boundary; • General Plan text amendment to align the plan boundary indicated on the General Plan Land Use Element with the boundary proposed for the NLSP area. Under this amendment, a few areas would be removed from the current plan, while additional parcels would be incorporated into the area;

CHAPTER 2

PROJECT DESCRIPTION

2.1 Introduction
On August 18, 2015, the City certified the Pasadena General Plan (GP) Final Environmental Impact Report (GP EIR). The GP EIR analyzed potential citywide impacts, broad policy alternatives, and programmatic mitigation measures. The GP EIR analyzed the update of the GP and specific plan amendments, which were limited to specific plan boundary changes and updated development caps within each of the City’s eight specific plan areas. The changes focused on the Land Use and Mobility Elements and the Land Use Diagram. The update also included the consolidation of optional elements into required elements of the General Plan.

The Land Use and Mobility Elements, together with the other General Plan elements, guide the overall physical development of the City through horizon year 2035.

The City is updating seven existing specific plans and creating one new specific plan to align with the updated 2015 General Plan. The specific plan updates focus on establishing neighborhood-specific design and land-use goals resulting in new development standards and guidelines that will help shape the City’s major commercial and mixed-use areas. The NLSP is one of the seven existing specific plan s to be updated as part of the General Plan Implementation Program.

The purpose of this Addendum to the GP EIR is to evaluate the environmental effects associated with the proposed NLSP Update and to determine whether these impacts are consistent with the evaluation presented in the GP EIR in compliance with CEQA (Public Resources Code Sections 21000 et seq.) and the State CEQA Guidelines (California Code of Regulations Section 15000 et seq.).

2.2 Project Location
The proposed NLSP area is generally bounded by Maple Avenue and the I-210 Freeway to the south; Elizabeth Street to the north; Catalina Avenue, Mentor Avenue, and Wilson Avenue to the east ; and El Molino Avenue and Hudson Avenue to the west. The existing NLSP boundary extends along a 1.38-mile segment of North Lake Avenue between the I -210 Freeway to the south and Elizabeth Street to the north. The Metro A Line Lake Station is located just outside the existing NLSP boundary to the south.

Figure 1 shows the general location of the existing NLSP area within the region . Figure 2 shows the NLSP Update area among the general locations of the City’s eight Specific Plans that make up the General Plan Implementation Program.

2.3 Project Objectives
The primary goals and objectives identified in the 2015 GP EIR include:
• Objective 1: Provide a new Land Use Element that targets growth to serve community needs and enhance the quality of life. Direct higher density development away from residential neighborhoods and into the Central District, Transit Villages, and Neighborhood Villages.
• Objective 2: Reduce vehicle miles traveled for the City and the region by providing a diverse housing stock, job opportunities, and exciting districts with commercial and recreational uses, and transit opportunities in the Central District, Transit Villages, and Neighborhood Villages.
• Objective 3 : Ensure new development builds upon Pasadena’s tradition of strong sense of place, great neighborhoods, gardens, plazas, parks, and trees. • Objective 4 : Preserve Pasadena’s historic resources by ensuring that new development is compatible with and differentiated from existing historic resources. • Objective 5 : Achieve economic vitality and fiscal responsibility by providing jobs, services, revenues, and opportunities with a diverse economic base. • Objective 6: Provide a General Plan that establishes the goals and policies to create a socially, economically, and environmentally sustainable community. Provide safe, well-designed, accessible, and human-scale residential and commercial areas where people of all ages can live, work, and play, including neighborhood parks, urban open spaces, and the equitable distribution of public and private recreational facilities. • Objective 7: Create a cultural, scientific, corporate, entertainment, and educational center for the region. Provide long -term growth opportunities for existing institutions and foster a healthy economy to attract new cultural, scientific, corporate, entertainment, and educational institutions.
• Objective 8: Create mobility guidelines and multimodal metrics consistent with Senate Bill (SB) 743. Incorporate new goals, policies, and programs that balance multiple modes of transportation and meet the requirements of the Complete Streets Act. • Objective 9 : Reduce greenhouse gas emissions and encourage walking, biking, transit, and other alternatives to motor vehicles by creating strategies to encourage nonautomotive travel and protect residential neighborhoods consistent with Assembly Bill (AB) 32, SB 375, and SB 743.
• Objective 10 : Reconcile General Plan buildout projections with regional and subregional estimates for growth creating consistency with the Southern California Association of Governments (SCAG).
• Objective 11: Incorporate housing sites identified in the adopted Housing Element Chapter 2: Project Description North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 2 ends

with the Land Use Element.

In accordance with the GP EIR goals and objectives, the proposed NLSP Update includes the following vision statement:

Vision Statement: The vision of North Lake Avenue is a vibrant and visually cohesive corridor, weaving together several distinct pedestrian-oriented districts that complement and build upon the cultural and architectural history of the community and its surrounding neighborhoods.

Vision Objectives:
• Sustainable Growth: A lively mix of new residential and neighborhood -serving retail shops, restaurants and services, close to transit and open space. • A Sense of Place. Places with a unique identity and character that people want to visit, built around engaging gathering spaces and inviting streetscapes. • High-Quality Homes. Well-designed multi -family housing that creates varied and affordable options to fit all kinds of Pasadena residents and families. • Economic Vitality. Small businesses and local institutions that contribute to the area’s economy, providing jobs as well as other benefits to the area. • Walkable Neighborhood. Sidewalks designed for pedestrian comfort, safety, and mobility, with easy connections to people’s daily needs and multimodal transport. • Green Community. Attractive streets lined with consistent, healthy tree canopies and landscaping that will support climate resiliency and improve public health.

2.4 Description of the Proposed Project
The proposed project would update the NLSP to implement the General Plan. As part of the proposed project, a General Plan Land Use Diagram amendment would be adopted so that the Land Use Diagram is consistent with the boundaries and land use categories proposed in the NLSP Update. The purpose of this Addendum to the GP EIR is to evaluate the environmental effects associated with the proposed NLSP Update as compared to the evaluation presented in the GP EIR.

This project proposes to update the following components of the NLSP to bring it into alignment with the General Plan:
• Specific Plan Area boundary
• Vision, objectives, goals and policies
• Zoning districts regulating allowed land uses
• Density and intensity of development
• Height and/or overall scale of buildings and structures • Distance of buildings and structures to the property line (setbacks/stepbacks) • Urban design standards
• Vehicle access and parking standards
• Types and amount of open space and landscaping requirements Chapter 2: Project Description North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 2 ends

• Public realm standards (sidewalks, parkways and street trees) • Implementation programs
Updates to the NLSP primarily focus on refining and/or establishing land uses and zoning districts, as well as objective development standards to achieve the goals and vision of the General Plan. This includes building upon the NLSP area’s existing strengt h as a neighborhood corridor with a mix of uses, walkable areas with shopping, restaurants, offices, and housing. Updates to the NLSP seek to stimulate housing and commercial development, encourage pedestrian-oriented retail and services, support pedestria n mobility, and target housing opportunities in a contextually sensitive manner. Through incremental development, the NLSP would strengthen North Lake’s role as a local “main street”, providing a wider variety of amenities, services, and housing options to residents, employees, and visitors. To support the land use and zoning district updates, the NLSP Update includes urban design standards related to scale, frontages, open space, and parking to encourage quality architecture that enhances the community’s unique character. Standards for the public realm are also included in the NLSP Update to address and regulate pedestrian infrastructure and amenities to support a safe, accessible, and comfortable pedestrian experience, including sidewalks, parkways, and street trees. The NLSP Update does not address public roadway modifications or improvements, which are within the purview of other City documents.

2.4.1 Relationship to 2015 General Plan
The 2015 General Plan represented an update to the City General Plan Elements, including the Mobility Element and the Land Use Element, which guide the overall physical development of the City. The 2015 General Plan also established new development caps fo r each of the Specific Plan areas, including the NLSP. However, the General Plan leaves the more detailed development and design standards to be identified in the Specific Plan. The proposed NLSP Update establishes the regulatory tools needed to implement the General Plan through the identification of development and design standards suited to the NLSP area. As this document compares the environmental impacts of the proposed NLSP Update to those analyzed in the GP EIR, it is important to note the following:
• The proposed NLSP Update does not modify or change the intent of the adopted General Plan. Rather, the updates to the NLSP are being proposed to achieve the goals and vision of the General Plan by adding the necessary regulatory tools for implementation. Additionally, a Zoning Code amendment would be required to incorporate a new NLSP ordinance to regulate zoning consistent with the General Plan, replacing the existing Pasadena Municipal Code Chapter 17.34. • The General Plan established land use and corresponding density and intensity ranges but did not establish development and/or design standards (e.g., height limits, setbacks, etc.). The NLSP Update adds more specific standards to implement the General Plan Land Use categories for the NLSP area. It provides those development and design standards through zoning districts and land use regulations, thereby, further regulating the land uses studied in the GP EIR. • The proposed NLSP Update follows the plan area boundary with minor revisions noted below, and sets densities and intensity standards which are within the General Plan ranges with the exception of the following recommended amendments:
o Update the land use designation for parcels north of Washington Boulevard and west of Washington Theater from Medium Mixed-Use (0-87 du/ac and 0- Chapter 2: Project Description North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

o Update the land use designation for parcels southwest of Washington Boulevard and Hudson Avenue from Medium Mixed-Use (0-87 du/ac and 0-

2.25 FAR) to Low-Medium Mixed-Use (0-48 du/ac and 0-1.75 FAR).

o Remove the area northeast of Hudson and Claremont from the NLSP and update the land use designation from Medium Mixed-Use (0-87 du/ac and 0-

2.25 FAR) to Medium-High Residential for the northernmost three parcels and to Low-Density Residential (0-6 du/ac) for the southernmost four parcels.

o Update the land use designation for parcels southeast of Washington Boulevard and North Lake Avenue from Medium Mixed-Use (0-87 du/ac and 0-2.25 FAR) to Low Mixed-Use (0-32 du/ac and 0-1.0 FAR).

o Update the land use designation for parcels south of Washington Boulevard between Mentor and Catalina avenues from Medium Density Residential (16 du/ac) to Low Mixed-Use (32 du/ac and 0-1.0 FAR).

o Update the land use designation for parcels at North Lake Avenue and Mountain Street south to Orange Grove Boulevard from Low Commercial (0-

1.0 FAR) to Low-Medium Mixed-Use (0-48 du/ac and 0-1.75 FAR).

o Add the parcel at 826 Boylston to the NLSP and update the land use designation from Medium-High Density Residential (0-32 du/ac) to Low- Medium Mixed-Use (0-48 du/ac and 0-1.75 FAR).

o Add the parcel at 840 Earlham Street and change the land use designation from Institutional to Medium Mixed-Use (0-87 du/ac and 0-2.25 FAR).

o Add the parcels at 819 East Villa Street and 812-834 Santa Barbara Street and update the land use designation from Low-Medium Density Residential (0-12 du/ac) to Medium Mixed-Use (0-87 du/ac and 0-2.25 FAR).

2.4.2 Relationship to 1997 North Lake Specific Plan
The existing North Lake Specific Plan was adopted by the City Council in 1997 and amended on June 25, 2007 . The 2015 GP and corresponding GP EIR included some policies carried over from the 1997 North Lake Specific Plan (1997 SP). The purpose of the 1997 NLSP was to provide a safe pedestrian environment, support development near the Gold Line station, and minimize vehicle intrusions and its associated uses such as vehicles sales and drive - through businesses . The 1997 SP explored the relationship between land uses, design standards, and economic strategies to help accomplish the goal of healthy pedestrian - oriented and transit -oriented neighborhoods serving mixed -use business and residential districts. As such, the development and design standards listed in the 1997 SP are applicable to the parcels in the NLSP area until the NLSP Update being analyzed in this Addendum is adopted.

The proposed updates to the NLSP would build on the progress initiated by the 1997 SP and further the vision set by the 2015 General Plan by establishing land uses and zoning districts for a more cohesive approach to mixed -use development and public realm connectivity to support transit usage. The specific plan land uses organize land use types by zoning districts while development standards such as height restrictions, density limitations, parking requirements, public realm, etc. are regulated by location-based maps. The primary changes between the 1997 SP and the NLSP Update are updated policies and standards that align with the General Plan and address current and future community needs, opportunities, and challenges.

2.4.3 Proposed NLSP Updates
The vision and goals of the proposed NLSP Update are implemented through three sets of tools set forth in the NLSP. These tools include land use regulations, design and development standards, and public realm standards. The unique characteristics of North Lake are articulated through defined subareas. Each subarea is implemented by one or more zoning districts that regulate permitted land use types. Figure 4 shows proposed subareas.

Development standards are regulated by location, not zoning districts, and include standards that improve building design and require site design that complements existing defining features of the neighborhood’s built form, such as consistent setbacks, open space requirements, parking location requirements, and landscaping. General discussions on the development and design standards to be implemented under the NLSP Update are included below.

The zoning district naming conventions reflect their location within a specific plan (NL is used as the zone prefix) as well as the land uses allowed within that zone. The proposed zoning districts would become effective once codified following Council adoption of the proposed NLSP Update. Figure 5 shows proposed zoning districts for the NLSP area.

Specific Plan Boundary
As discussed in Section 2.2, the proposed NLSP area is generally bounded by Maple Avenue and the I-210 Freeway to the south; Elizabeth Street to the north; Catalina Avenue, Mentor Avenue, and Wilson Avenue to the east; and El Molino Avenue and Hudson Avenue to the west. Specific modifications to the proposed plan boundary are described above in the Relationship to the 2015 General Plan section.

Land Use
The proposed updates to the NLSP would update zoning districts tailored to current community needs in alignment with the General Plan vision. The focus of the NLSP Update allows for financially feasible commercial and residential developments, and helps ensure that new buildings, streetscape improvements, and added amenities contribute positively to the pedestrian experience. This updated approach to land use regulation would support a mixed- use area that creates a range of opportunities for higher -density, transit-oriented development, served by multimodal linkage s, and pedestrian open space amenities. The NLSP Update would contain the following zones and corresponding objectives:
• Mixed-Use Core (NL -MU-C) – create mixed -use activity centers that encourage a range of active uses where people can walk to shops, restaurants, jobs, and entertainment in proximity to transit ; s upport projects that are entirely commercial, entirely residential, or mixed -use, with ground floor commercial required at key intersections.
• Mixed-Use Neighborhood (NL -MU-N) – promotes the development of pedestrian friendly neighborhoods with commercial uses that are sensitive to neighboring residents; support projects that are entirely commercial, entirely residential, or mixed- use, integrated either horizontally or vertically consistent with ground floor use requirements.
• Residential Multi-family (NL-RM-48/32/16) – maintain the current uses and protect the existing residential character using City of Gardens standards. • Residential Single -family (NL -RS-6) – provide areas for low density residential neighborhoods and relate new development to the existing environment. • Open Space (OS) – provide opportunities for parks and recreation to residents and visitors.
• Public Semi-Public (PS) – provide for large public or semi -public land uses that may not be appropriate in other base zoning districts.

Mass and Scale, Intensity and Density
The General Plan 2015 Land Use Element designates intensities and density ranges in the NLSP area to support the vision of a series of pedestrian -oriented villages and districts with unique identities, bolstered by their vibrant mix of uses, amenities, and streetscapes. Updates included in the NLSP are intended to:
• Implement the General Plan density ranges , measured as dwelling units per acre (du/ac), and intensity by floor area ratios (FAR);
Chapter 2: Project Description North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 2 ends

• Shape development in a manner that creates a defined public realm and appropriate scale of buildings for a visually appealing community;
• Reduce building massing through setback and stepback requirements that create appropriate transitions to residential neighborhoods;
• Support high-quality architecture and urban design through modulation requirements and a height averaging incentive;
• Require appropriate transitions to designated historic resources; and • Support opportunities to increase housing near transit and require various unit sizes to support individuals and families.

The Specific Plan generally implements the allowed density (du/ac) ranges and intensity (FAR) set by the General Plan Land Use Diagram and regulates density within the maximum density studied by the General Plan EIR.

Urban Design
Design standards for ground floor frontages proposed by the NLSP Update would help refine building mass and scale and support high -quality architecture and urban design. Frontage standards would prioritize pedestrian access by ensuring doorways are open to a public sidewalk or other public space; increase visibility into ground floor uses to create visual interest for pedestrians; promote shade through arcades and shade structures; support a consistent character when different uses are allowed on the ground floor within the same black; and limit blank walls on the ground floor to enhance visual interest and pedestrian comfort. The proposed standards are established for each block and are complementary to the previously discussed land use permissions. In mixe d-use districts, ground floor requirements are regulated by frontage type, with varying setback depths depending on the percentage of commercial or residential ground floor space to allow for common space and other amenities. A successful ground floor design would create an inviting, visually engaging, shaded sidewalk and pedestrian environment that supports the intended commercial, residential, or mixed-use character of each district. Proposed ground floor standards would reflect community interest to improve the pedestrian experience at the street -level based on the following parameters:
• Façade Modulation
• Ground Floor Height
• Location of Primary Entrances
• Amount of Street-Facing Transparency
• Minimization of Blank Walls
Open Space
The proposed updates to the NLSP would include open space requirements that would support high quality, accessible and usable open space across a variety of types that contribute to an active public realm and successful building design. Residential open sp ace would be required based on the number of bedrooms, which would result in larger units having a larger open space requirement. Required open space may be private to individual units or common among tenants. The amount of publicly accessible open space required is also based on the size of a proposed project. These changes are intended to expand the amount of open space available to residents and employees along the corridor.

Chapter 2: Project Description North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 2 ends

Parking
Vehicle parking requirements proposed by the updates to the NLSP would lower the parking requirement for some commercial uses to allow more flexibility for business owners as uses change over time; these modified standards are designed to support economic stability and reduce vacancies through simplified regulation. Residential parking requirements would also be reduced in part of the plan area not exempt from parking requirements by State law. The NLSP further proposes as a future implementation action a Streetscape Program for North Lake Avenue which could study the feasibility of modifying the cross-section of the street and potentially changing its on-street parking.

Public Realm & Setbacks
Public realm requirements proposed by the NLSP Update would improve sidewalk conditions and the pedestrian experience by ensuring that a minimum sidewalk width is achieved by reinforcing existing widths or requiring slight increases in key locations as new development occurs. The NLSP Update builds on the Pasadena Street Design Guide to ensure sufficient widths to create a sidewalk environment that supports functional activities.

The sidewalk width requirements would correlate with the level of activity and surrounding densities, intensities, and uses identified in the NLSP area and address community desire for wider sidewalks. New width requirements for sidewalk zones of at least 12 -feet will support adequate space for street trees, parkways, pedestrian movement, and other amenities. The NLSP Update would require parkways and street trees to be provided by new development, and trees would be required to be planted in larger tree we lls and follow new planting requirements to better support tree health.

As mentioned in the open space sub -section, some developments in the NLSP area are required to provide plazas or paseos, particularly near the major intersections of North Lake Avenue/Villa Street and North Lake Avenue/Washington Avenue, to meet requirements for publicly accessible open space. Proposed requirements and guidelines are intended to increase pedestrian connectivity and visual interest by reducing large block sizes and providing additional publicly accessible open space , improving walkability and creating safe spaces for pedestrian gathering and movement.

CHAPTER 3

EVALUATION OF ENVIRONMENTAL IMPACTS

The following evaluation assesses the environmental impacts of the proposed NLSP Update in relation to the analysis provided in the 2015 GP EIR. Determinations are made as to whether the proposed project would result in new significant impacts or substantially more severe effects, which would trigger the need for a Subsequent or Supplemental EIR.

For each threshold identified below, the following questions are addressed and discussed in the narrative for each issue:

What is the NLSP Update’s impact conclusion?
For each impact identified below, a level of significance of the impact is provided. While criteria for determining significant impacts are unique to each issue area, the environmental analysis applies a uniform classification of the impacts based on the following definitions consistent with CEQA and its implementing CEQA Guidelines:
• No Impact (NI) – A designation of no impact is given when no changes in the environment would occur.
• Less than Significant Impact (LTS) – A less than significant impact would cause no substantial adverse change in the environment.
• Less than Significant Impact with Mitigation (LTS-M) – A less than significant impact with mitigation incorporated avoids substantial adverse impacts on the environment with adherence to identified mitigation measures. For those issue areas where the impact of the NLSP Update would be less than significant with the incorporation of the same mitigation measure(s) identified in the GP EIR, the impact is identified as LTS-M(GP). The number of the mitigation measure from the MMRP will be referenced and summarized in Chapter 4.
• Significant and Unavoidable Impact (S-U) – A significant unavoidable impact would cause a substantial adverse effect on the environment, and no feasible mitigation measures would be available to reduce the impact to a less than significant level.

What is the GP EIR impact conclusion? The issues that were found to be either less than significant or were found to have no impact in the Initial Study prepared for the GP Update and were therefore excluded from further analysis in the GP EIR, are identified with (IS) after the impact conclusion.

Does the NLSP Update involve new significant impacts or substantially more severe impacts than those analyzed in the GP EIR?
Are there any new or changed circumstances involving new significant impacts or substantially more severe impacts than those analyzed in the GP EIR?

The GP EIR concluded that implementation of the approved General Plan Update, specifically including buildout of the NLSP area, would result in less than significant environmental impacts to aesthetics. While buildout of the General Plan would result in redevelopment in the NLSP area, the GP EIR found that development in accordance with the General Plan Land Use Element would not significantly impact views of the San Gabriel Mountains . The GP EIR concluded because the north –south alignment of the street grid and the low -density nature of the neighborhood would be preserved; continued views of the San Gabriel Mountains would be available at buildout.

As detailed in Section 2.4, proposed updates to the NLSP primarily focus on refining and/or establishing land uses and zoning districts, as well as objective development standards to achieve the goals and vision of the General Plan.

districts that allow for the development of higher intensity mix of retail, office, and multi -family housing uses in proximity to the Metro A Line station that expand the customer base for local businesses. Updates included in the proposed NLSP are intended to implement the densities and intensities analyzed in the GP EIR, shape development in a manner that creates a defined public realm and appropriate scale of buildings for a visually appealing community, reduce building massing through setback and stepback requirements that create appropriate transitions to residential neighborhoods, support high-quality architecture and urban design through modulation requirements and a height averaging exception , and require appropriate transitions to designated historic resources. To accomplish this, the NLSP Update generally implements the allowed density ranges and intensity set by the General Plan Land Use Diagram and regulates density within the maximum density studied by the General Plan EIR. Overall, the GP EIR concluded that proposed land use changes in the General Plan Update, and specifically as they pertain to the NLSP area, would not adversely impact visual and scenic quality, but would instead ensure that established residential neighborhoods would not be adversely affected by new mixed-use and commercial projects.

As the proposed NLSP Update would align with and implement the General Plan, buildout of the NLSP Update would not significantly impact visual character or quality.

Additionally, as discussed in the GP EIR, there are no designated state scenic highways located within the NLSP area. Although permitted development under the approved General Plan Update could result in increased light and glare, the NLSP area is primarily developed, Chapter 3: Evaluation of Environmental Impacts North Lake Specific Plan Update

Furthermore, the current CEQA Guidelines Appendix G checklist also recommends considering a project’s potential to conflict w ith applicable zoning and other regulations governing scenic quality if the project is located in an urbanized area. As discussed, the proposed NLSP updates include additional land use regulations and establish development/design standards. Similar to the General Plan Update, these NLSP updates would not significantly impact views of the San Gabriel Mountains and would improve the aes thetic quality of new development as well as help refine the existing character within the NLSP area through enhancements to the public realm . Therefore, impacts related to scenic quality would be less than significant with implementation of the NLSP Update.

No new significant impacts and no substantial increase in the severity of previously identified impacts associated with the p roposed project would occur. Likewise, there is no new information of substantial importance requiring new analysis or verification. The project does not propose substantial changes that require major revisions to the GP EIR, and no new mitigation measures are required.

The SCAB is designated a nonattainment area (i.e., an area that does not meet the ambient air quality standards) for ozone (O3), fine inhalable particulate matter (PM2.5), and coarse inhalable particulate matter (PM10) under the CAAQS, and a nonattainment area for O 3, PM 2.5, and lead (Los Angeles County only) under the NAAQS.3 The GP EIR concluded that buildout of the General Plan Update would increase employment and population beyond current SCAG forecasts and contribute to cumulative SCAB nonattainment designations. While certain aspects of the General Plan Update Land Use Plan would lead to improvements in transportation and thus decrease emissions from that source, the GP EIR found that even with implementation of Mitigation Measure 2 -1, requiring the preparation of a technical assessment evaluating potential project construction-related air quality impacts to the City Planning Division prior to issuance of construction permits, and Mitigation Measure 2-2, requiring the preparation of a technical assessment evaluating potential project operation-related air quality impacts to the City Planning Division prior to project approval, construction and operation impacts would not be reduced below the required SCAQMD thresholds, and that future impacts could be significant and unavoidable. The GP EIR stated that although submission of a technical assessment for possible construction related impacts required by Mitigation Measure 2-1 could reduce criteria air pollutant impacts for individual projects, the cumulative impact of all future construction emissions would result in sig nificant and unavoidable impacts. In relation to the operation of buildout, the GP EIR stated that future activity would exceed SCAQMD thresholds

The HRA prepared for those projects identified under Mitigation Measure 2 -3 would identify project -specific measures to minimize health risk and individual projects would be required to achieve the incremental risk thresholds established by SCAQMD, thus reducing impacts to less than significant. This, however, would only reduce the impact on a project-by-project basis, and the GP EIR concluded that the future buildout of the General Plan Update would result in cumulative impacts to sensitive recept ors that are significant and unavoidable. The GP EIR found that Mitigation Measures 2 -4 and 2 -5 would require that major sources of air pollutants achieve incremental risk thresholds when placed near a sensitive receptor, as well as practice measures to minimize od ors, reducing both impacts to a less than significant level.

No land use changes were proposed in these areas; however, the GP EIR states that buildout of the General Plan Update could have potentially significant impacts to sensitive species, sensitive natural communities, and jurisdictional waters and/or wetlands.

Mitigation Measures 3 -1 through 3 -6 would ensure that a qualified biologist would be involved in the assessment, mitigation, and monitoring of all projects occurring on land where impacts to biological resources could be potentially significant; impacts would then be reduced to a less than significant level following implementation of the mitigation measures. The IS prepared for the GP EIR found that development projects approved under the GP Update, including within the City’s eight specific plan areas , would be required to comply with the City’s Master Street Tree Plan, Chapter 17.44 (Landscaping) of the City’s Zoning Code, and the Migratory Bird Treaty Act (MBTA), as applicable. As such, the General Plan Update’s impact on overland wildlife movement and m igration would be less than significant and the General Plan Update would not conflict with the City’s tree protection ordinance.

The GP EIR found that, while the General Plan Update did not propose the alteration or demolition of any historic landmarks, any development under buildout of the General Plan Update could potentially impact a historic resource, as the GP EIR lists 7,440 historical resources throughout the City which meet at least one state or national criteria. The GP EIR states that the likelihood of encountering and impacting a historical resource is greater within a historic district, and that any specific plan area tha t is within or adjacent to a historic district has a greater likelihood for impacting historical resources. The Central District, North Lake, and Fair Oak s/Orange Grove Specific Plan Areas contain and/or are adjacent to historic landmarks and/or historic distri cts. The GP EIR states that future projects under the buildout of the General Plan Update can avoid significantly impacting historical resources by adhering to the Pasadena Municipal Code 17.61.030 design review, to state and federal regulations, and to the policies of the City’s Land Use Element, including Policy LU 8.5, Scale and Character of New Construction in Designated Landmark and Historic Districts.

The proposed NLSP Update is located within the boundaries of the area that was captured under the IS and GP EIR. New developments in the NLSP area would be required to comply with the California Energy Code, Part 6 of the California Building Standards Code (Title 24), CALGreen standards, the City’s Climate Action Plan, and the City’s Green Building Standards Code, which collectively would increase efficiency and decrease consumption levels. Any new developments in the NLSP area would require lateral connections to mainlines in coordination with existing utility service providers. While the land use types under the proposed NLSP Update would encourage multifamily residential and mixed -use zoning, and thereby potentially increase demand in energy over existing conditions, the proposed NLSP area is largely developed and urbanized under existing conditions, and this increase in

respectively. All active faults could experience a surface rupture in the lifetimes of development resulting from buildout of the General Plan Update. The Safety Element, California Building Code, the City’s Building and Safety Division, and the City Build ing Code would require all new development to comply with policies and regulations surrounding surface ruptures and would be required to con duct and submit engineering geology and soils reports prior to permit approval. Policies within the above stated regulatory setting would also enforce specific building standards related to seismic ground shaking, as the soil in the City is either sandy, stony, or gra velly loam formed on the alluvial fan adjacent to the San Gabriel Mountains, which are soil types charac terized as loose and porous and thus susceptible to seismic ground shaking. Geotechnical investigations be required for all new development approval as the City contains zones where liquefaction could occur near Arroyo Seco, in the San Rafael Hills, and ne ar Eaton Canyon and Hastings Canyon. State and City building codes contain standards that new development must comply with pertaining to liquefaction as well. Geotechnical investigations would also be required to investigate and recommend measures to reduce the potential for landslides and building designs would be required to comply with slope standards, as the City is susceptible to earthquake -induced landslides originating in the San Gabriel Mountains and San Rafael Hills. The IS concluded that natural water soil erosion potential in the City is low, that future construction has the possibility to expose soil to erosion, and that all construction activity would be required to practice soil erosion mitigation practices and adhere to a transport and grading control plan as required by the Los Angeles County Stormwater Program.

The above-mentioned potential for landslides and liquefaction in addition to the susceptibility to lateral spreading and/or collapse due to the project location and quality of the soil would need to be included in each geotechnical investigation.

The proposed NLSP falls within the same City boundaries as were analyzed in the IS, and therefore is subject to similar risks and associated potential impacts related to geology and soils. Therefore, the NLSP Update would not cause significant impacts beyond those analyzed in the IS for the GP EIR. Additionally, buildout of the proposed NLSP Update would be required to adhere to the same regulations, policies, and standards pertaining to geology and soil s impacts, both during construction and operation, including the preparation of project-specific geotechnical investigations for individual development projects.

The GP EIR concluded that while certain improvements under the buildout of the General Plan Update would reduce Greenhouse Gas (GHG) emissions per service population, the buildout would still create more GHG emissions than existing conditions and would not achieve long-term GHG reduction goals under Executive Order S -03-05 and target levels of AB 32; after implementing Mitigation Measure 5-1, which required the City to prepare a community climate action plan/greenhouse gas reduction plan, the impacts related to GHG emissions would remain significant and unavoidable. Forecasting tools to measure future emissions from transportation, energy, waste, water/wastewater, and other sources (landscaping equipment, light commercial equipment, and construction equipment) provided a short -term projection for future levels; however, these projections were found to be insufficient given the uncertainty of how the General Plan Update buildout would be phased. The GP EIR found that without implementation of a community climate action/GHG reduction plan and under current state and federal regulations, the population growth that would result from buildout of the General Plan Update would prevent the City from meeting AB 32 targets for emissions. While buildout would imp rove transportation by creating a live/work environment, offering options for alternative and multi-modal mobility, and utilizing energy efficient design and technology, the GP EIR stated that the population growth would still create more emissions than existing c onditions. The community climate action plan/greenhouse gas reduction plan would establish community -wide targets, monitoring , and inventory reporting standards. The GP EIR established that the community-wide GHG emissions inventory would be updated every five years, and additional programs would be established to work in conjunction with the initial community climate action plan/greenhouse gas reduction plan (programs specific for building energy, transportation, waste, water, wastewater, agriculture, etc. ).

The proposed NLSP Update would further restrict the land uses from those analyzed in the GP EIR and establish additional development/design standards. The proposed NLSP Update would allow for increased intensity within the NLSP area compared to existing conditions; however, proposed density would be equal to or lower than limits analyzed under the GP EIR. Additionally, buildout of the NLSP Update would be within the General Plan buildout analyzed in the GP EIR. The NLSP improvements included in the proposed NLSP Update would create a district that supports a mix of housing and commercial development near transit and existing services to encourage walkability and transit usage, all supported by a public realm that invites residents, employees, and visitors to walk the district, with active streetscapes, open spaces, and rich landscaping that encourages public life and a sense of place. Buildout of the proposed NLSP Update would address the following goals and policies proposed by the General Plan Update for the City’s Land Use Element for North Lake: Goal 36, Policy LU 36.2: Provide for the development of a higher intensity mix of retail, office, and multi- family housing uses in proximity to the Metro A Line station that expand the customer base for local business and support Metro A Line ridership contributing to the reduction of vehicle trips, energy consumption, and GHG emissions; and Goal 36, Policy 36.5: Design Chapter 3: Evaluation of Environmental Impacts North Lake Specific Plan Update

The GP EIR found that buildout in accordance with the General Plan Update would involve the transport, use, and/or disposal of hazardous materials; however, impacts would be less than significant as construction would be short -term and in compliance with California Health and Safety Code, Occupational Safety and Health Administration (OSHA), and SCAQMD regulations; project operations would reduce industrial uses compared to existing conditions and new development would comply with the City’s Safe ty Element. The GP EIR found that 844 hazardous material sites fall within the City or within a 0.25 -mile radius thereof; however, compliance with the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), Resource Conservation and Recovery Act (RCRA), California Code of Regulations, Title 22, and related requirements, as well as adherence to the City’s Land Use Element Policy LU 3.5 Hazardous Uses would bring the impact level to less than significant. The GP EIR concluded that project development could affect the implementation of an emergency response or evacuation plan due to population growth, development intensity, and road closures during construction; however, coordination with the Pasadena Fire Department (PFD) and compliance with the Los Angel es County Operational Area Emergency Response Plan and the City’s Emergency Operation Plan would ensure each project and buildout of the General Plan Update has a less than significant impact related to this topic. Finally, the GP EIR found that areas of the City near very high fire hazard severity zones could expose structures and/or residences to fire hazards during buildout of the General Plan Update. However, compliance with the International Fire Code, California Fire Code, and the City’s Safety El ement would ensure that future development under the General Plan Update would not expose people or structures to substantial wildfire hazards, and impacts would be less than significant.

Similar to the buildout analyzed in the GP EIR, construction under the proposed NLSP Update could potentially involve the transport, use, and/or disposal of hazardous materials. However, the further regulation of land uses under the proposed NLSP Update would reduce industrial uses compared to existing conditions. Additionally, construction associated with individual development projects under buildout of the NLSP Update would be temporary in nature, and development would comply with the California Health and Safety Code, OSHA, and SCAQMD regulations. The NLSP Update is not expected to result in significant impacts related to the transport, use, and/or disposal of hazardous materials. The GP EIR did not list any hazardous material sites in the NLSP area; however, if a site were to be located with a 0.25 -mile radius of the NLSP area, future development would be required to comply with CERCLA, RCRA, California Code of Regulations, Title 22, and related requirements, as well as adhere to the City’s Land Use Element Policy LU 3.5: Haza rdous Uses. As a result, hazardous material-related impacts would be less than significant. Future development under buildout of the NLSP Update could result in temporary road closures. Similar to the GP Update analyzed in the GP EIR, future development under buildout of the NLSP Update would be required to coordinate with the PFD. Additionally, buildout of the NLSP Update would not interfere with the Los Angeles County Operational Area Emergency Response Plan or the City’s Emergency Operation Plan.

The GP EIR found that buildout of the General Plan Update could increase the amount of impervious surfaces in the City of Pasadena resulting in an increase in surface water flows into drainage systems within the watershed, potentially resulting in erosion, siltation, and/or flooding. However, the City is primarily developed and urbanized and development would be required to adhere to applicable local, state, and federal regulations and standards, as well as implement site design measures, low -impact development, and best management practices (BMPs), including infiltration features that contribute to groundwater recharge and minimize stormwater runoff, erosion, siltation, and/or flooding. As such, these impacts would be less than significant. The GP EIR stated that with the implementation of evacuation plans, as required by the City’s Safety Element, the impact to risk of loss, injury, or death in the case of dam failure less than significant. The GP EIR found that during the construction phases of projects developed under the General Plan Update, there is the potential for short-term unquantifiable increases in storm water pollutant concentrations; and during operation of such projects, the quality of storm runoff (sediment, nutrients, metals, pesticides, path ogens, and hydrocarbons) may be altered.

The proposed NLSP Update would further restrict land uses from those analyzed in the NLSP area in the GP EIR and would establish additional development/design standards. The NLSP area is currently developed and urbanized. New development under the buildout of the proposed NLSP Update would be subject to applicable local, state, and federal regulations and standards pertaining to water quality, waste discharges, and hydraulic hazard risk reduction. Impacts to hydrology and water quality would be less than significant.

Furthermore, as indicated in the IS prepared for the GP, no portion of the City, including the NLSP area, is located within a 100 -year floodplain. Therefore, the proposed NLSP Update would not place structures within the flow of a 100 -year flood and no impact would occur.

The current CEQA Guidelines Appendix G checklist also recommends considering a project’s potential to conflict with or obstruct implementation of a water quality control plan or sustainable groundwater management plan.

The GP EIR stated that additional environmental impacts from changes to land use patterns and building intensity and design, such as impacts to air quality, hazards, flooding, and traffic, would be addressed individually in each corresponding section. As such, the GP EIR found that the proposed updates would not conflict with any existing applicable policies or regulations and would be implemented in such a way that creates compatibility within the plan area; impacts to land use and planning were determined to be less than significant in the GP EIR. Additionally, the IS prepared for the GP EIR found that there are no adopted habitat conservation or natural community conservation plans within the City and, as such, concluded that no impacts to such plans would result fr om the General Plan Update.

The proposed NLSP Update would have similar land use objectives as the GP EIR and includes further regulations around land uses and establishment of additional development/design standards to reflect development patterns within the NLSP area that have occurred since adoption of the General Plan Update.

Regarding exposure to long-term groundborne vibration, the GP EIR found that both rail and industrial uses could cause a potentially significant impact. Portions of the City are designated for and operated as industrial uses. Mitigation Measure 9-1 requires all industrial projects to submit a vibration study providing evidence that vibration -causing activity would not exceed levels set forth by the Federal Transit Administration (FTA). The City of Pasadena is served by the Metro A Line. The portion of this line in the City runs north -south parallel to Arroyo Parkway and then turns to an east-west orientation along I-210, with its current terminus in the City of Azusa. Mitigation Measure 9-2 requires all new development within screening distance of the Metro A Line to submit a study conducted by an acoustic engineer to the City’s Planning Division that identifies vibration impacts and possible reduction measures, if needed. Implementation of Mitigation Measures 9-1 and 9-2 would reduce groundborne vibration impacts to a less than significant level.

The GP EIR concluded that short -term impacts from construction vibration would be significant and unavoidable for buildout of the General Plan Update; Mitigation Measure 9-3 would reduce impacts to sensitive receptors within 25 feet of activity by substituting less intensive equipment when possible and utilizing vibration reduction techniques; however, because each new development involved in the buildout is project-specific, the GP EIR determined it is not possible to mitigate this impact below a significant and unavoidable level.

Mitigation Measure 9-5 requires all construction permits to be issued only after submission of a plan for noise and vibration reducing BMPs for all development within 500 feet of a noise-sensitive receptor; nevertheless, the GP EIR concluded that this mitigation measure would not reduce the impacts of construction activities to a less than significant level as the phasing, location, and magnitude of future development under buildout is unknown. Therefore, the GP EIR concluded that construction related noise impacts are significant and unavoidable. The IS prepared for the GP EIR found that no portion of the City is located within an airport land use plan or w ithin two miles of an airport, and no impact would occur. Furthermore, the IS prepared for the GP EIR concluded that noise from helicopter flights would be periodic and, thus, the impact resulting from noise from private use heliports would be less than significant.

Buildout of the proposed NLSP Update could have potentially significant noise impacts due to construction-related noise and vibration, as the phasing and location of future projects are currently unknown. However, similar to the updates analyzed under the GP EIR, the proposed NLSP Update would implement GP EIR Mitigation Measures 9-3 through 9-5 to ensure activity within the vicinity of sensitive land uses, receptors, and architectural structures is compliant with FTA criteria and that BMPs are utilized throughout the construction Chapter 3: Evaluation of Environmental Impacts North Lake Specific Plan Update

The GP EIR concluded that, while population, housing, and employment growth induced by buildout of the General Plan update would likely surpass SCAG’s forecast, the impact of buildout would be less than significant. The General Plan Update accommodates growth in all sectors; it permits new housing opportunities and it opens more opportunities for employment. The GP EIR found that th e City- wide utilities and infrastructure required to service the projected buildout population would be sufficient, and each service is discussed in more detail within its individual section of this document ( i.e., Hydrology and Water Quality, Public Services, Transportation and Traffic, Utilities and Service Systems). One of the central objectives of the General Plan Update is to create a housing/job balance within a more work/live environment; the GP EIR found that buildout would achieve this goal, which would offset the detrimental impacts that growth would have. The IS prepared for the GP EIR found that the General Plan Update would increase the number of dwelling units by allowing higher intensity residential uses and mixed -use development and that growth in accordance with the proposed General Plan Update was not expected to displace existing housing or people, as the General Plan Update would increase the number Chapter 3: Evaluation of Environmental Impacts North Lake Specific Plan Update

The NLSP area previously analyzed by the GP EIR shares the same objective of creating a more balanced housing/job ratio. Since the GP EIR was certified, changes in development patterns within the NLSP have resulted in more opportunities for multifamily residential uses and mixed-use development, further achieving this goal. The NLSP area is primarily built out under existing conditions and buildout of the proposed NLSP Update would not exceed the projected growth analyzed in the GP EIR. Additionally, buildout of the NLSP Update would be within the General Plan buildout analyzed in the GP EIR , with some residential capacity transferred to a new mixed-use area that is currently a commercial-only zoning district. Therefore, similar to the GP EIR, the NLSP Update would not displace substantial numbers of housing or people, and the impacts would be less than significant.

The GP EIR found that, while population growth and increased infrastructure from buildout of the General Plan Update would result in higher demand for service from the PPD and possibly require new or expanded facilities, compliance with existing regulation s would ensure impacts remain less than significant. The GP EIR concluded that while population growth from buildout of the General Plan Update would create new students in the population, the majority of which would be concentrated in three specific plan areas including the NLSP area, it is unlikely that forecasted growth would exceed the capacity of existing facilities; additionally, per SB 50, all new development in the City is subject to a School Impact Fee to ensure that school services continue to meet the needs of the population.

The PPL operates 10 facilities, all within 1 mile or walking distance of each residence. The GP EIR found that while buildout of the General Plan update would induce population growth, the estimated growth would not exceed the PPL’s capacity to serve the Chapter 3: Evaluation of Environmental Impacts North Lake Specific Plan Update

The proposed NLSP Update would further restrict land uses from those analyzed in the GP EIR and establish additional development/design standards. The NLSP area is primarily built out under existing conditions and buildout of the proposed NLSP Update would not exceed the projected growth analyzed in the GP EIR. Additionally, buildout of the NLSP Update would be within the General Plan buildout analyzed in the GP EIR. Therefore, the proposed NLSP Update is not anticipated to increase demand for public services beyond the level analyzed in the GP EIR, and impacts would be less than significant.

No new significant impacts and no substantial increase in the severity of previously identified impacts associated with the proposed project would occur. Likewise, there is no new information of substantial importance requiring new analysis or verification. The project does not propose substantial changes that require major revisions to the GP EIR, and no new mitigation measures are required.

The City’s Municipal Code does not dictate a resident/acreage ratio for parkland and open space. While buildout of the General Plan Update would induce population growth and likely increase demand for parkland and open space and potentially result in the deterioration of existing facilities, the GP EIR found that improvements to existing and development of new open space and recreation amenities included in buildout, in conjunction with the Residential Impact Fee that each new development would be subject to as well as other in-lieu fees, impacts would be less than significant. The GP EIR concluded that the increase in population projected by buildout of the General Plan Update would increase demand for parkland, open space, and recreational facilities; increased use could deteriorate existing facilities or require the development of additional facilities. The GP EIR found that land uses permitting parkland, open space, and recreational activities would not be converted and that there would be opportunities for additional facilities to be built.

All residential development under the buildout of the GP would be required to pay a Residential Impact Fee; any type of project that acquires open space would also be subject to in -lieu fees. As such, the GP EIR found that impacts to recreation would be less than significant with adherence to existing regulations, including payment of applicable fees.

The GP EIR analyzed the General Plan Updates for impacts to traffic and transportation based on calculations for vehicle miles traveled (VMT) per capita, vehicle trips (VT) per capita, proximity and quality of bicycle networks, proximity and quality of transit networks, and pedestrian accessibility, as well as compatibility with the City’s Mobility Element. The GP EIR concluded that implementation of the General Plan Update would not conflict with the City’s plans, ordinances, or policies establishing measu res of effectiveness for the performance of the complete circulation system, and complies with adopted policies, plans, and programs for alternative transportation.

It found that transportation performance would improve, and pedestrian and bicycle accessib ility would increase from buildout of the General Plan Update, which would satisfy Mobility Plan goals around livability, non-motorized transit, and economic viability. The GP EIR stated that all improvements within the City are funded through the City’s transportation fee program with the exception of bicycle and pedestrian improvements. The proposed General Plan Update included Policy 2 .10, requiring the City to amend the existing transportation impact fee to include pedestrian and bicycle improvements.

However, these intersections and CMP Freeway Mainline Segments on Route 210 are not within the NLSP Update area.

The GP EIR also concluded that there was no feasible mitigation to reduce CMP impacts to a less than significant level, as improvements to road capacity would require changes to road infrastructure, which would have secondary impacts such as loss o f bicycle lanes, parking, sidewalk space, etc. that would conflict with General Plan goals and policies and would cause other impacts to traffic and transportation. As such, this impact was determined to be significant and unavoidable.

Roadways and mobility within the proposed NLSP area were analyzed within the GP EIR; the proposed NLSP Update does not include modifications to roadways and infrastructure outside of the project area analyzed in the GP EIR. While the modifications within the proposed NLSP would permit more residential units and uses, thus accommodating population growth, like the GP EIR concluded, the circulation improvements to which the proposed NLSP would contribute – improved sidewalk zones, bicycle and pedestrian accessibility, parking, proximity to live/work/shop for residents, allowing more residential and mixed use development in close proximity to the Metro A Line station – would be beneficial for the community and City as a whole. Further, per GP EIR Mitigation Measure 13- 1, each project developed under buildout of the proposed NLSP Update would be subject to whatever transportation impact fee is in effect at the time of permitting, thus ensuring that funds for future improvements would be available.

Additionally, the proposed NLSP Update would support the Department of Transportation’s Bicycle Transportation Action Plan by reinforcing pedestrian-friendly design and development and requiring bicycle parking.

The current CEQA Guidelines Appendix G checklist also recommends considering a project’s potential to conflict or be inconsistent with CEQA Guidelines Section 15064.3, subdivision (b), which requires the use of VMT as the updated measurement of traffic impacts, replacing the level of service (LOS) method previously used. As discussed, the GP EIR included a City-wide VMT analysis for impacts to traffic and transportation based on calculations for VMT per capita and VT per capita. The analysis used the City of Pasadena Travel Demand Forecasting (TDF) Model, which was validated to 2013 traffic conditions and later updated to reflect 2017 conditions. Both the 2013 and 2017 models assumed that the I -710 extension would be constructed by 2035, which is no longer a valid assumption.

As such, an assessment was conducted to update the model to reflect the 2035 horizon year without the I -710 extension.12 This assessment concluded that there were no substantial deviations from the VMT and VT analyses with the removal of the I-710 from the

Regarding other utilities, including electricity, natural gas, and communications, the GP EIR concluded that future development under the General Plan Update would be accommodated by existing service providers, and the impact would be less than significant. The GP EIR found that the project satisfied and complied with the City’s adopted General Plan Open Space and Conservation Element pertaining to water conservation, General Plan Safety Element pertaining to continued earthquake strengthening for utilities and protection of water supply, and state codes and regulations pertaining to utility services, and that the proposed updates to the General Plan Land Use Element regarding energy and water efficiency and conservation and solid waste reduction would create more sustainable standards for the future of the City. The IS prepared for the GP EIR found that buildout of the General Plan Update would be required to comply with all applicable solid waste regulations, including the California Integrated Waste Manage ment Act and the City of Pasadena Zoning Code Section 17.40.120 (Refuse Storage Facilities) and, as such, no impact related to compliance with solid waste regulations would occur.

Similar to the General Plan Update, future projects implemented under the NLSP Update would be required to adhere to all applicable solid waste regulations. Therefore, implementation of the proposed NLSP Update would have no impact related to compliance with solid waste regulations.

The current CEQA Guidelines Appendix G checklist also includes assessment criteria for potential impacts related to the relocation or construction of new or expanded electric power, natural gas, or telecommunications facilities. Similar to water, wastewater, and solid waste facilities, existing service providers would manage electricity, natural gas, and telecommunications services for projects under the proposed NLSP Update. As discussed, the NLSP area is primarily built out under existing conditions. Thus , it is anticipated that any new development in the NLSP area would require lateral connections to mainlines in coordination with utility service providers, similar to what occurs under existing conditions. Therefore, the NLSP Update would result in less than significant impacts related to the relocation or construction of new or expanded electric power, natural gas, and telecommunications facilities.

CHAPTER 4

MITIGATION MEASURES

The mitigation measures listed below are from the Pasadena General Plan Final Environmental Impact Report and would be applicable to the proposed project. No new mitigation measures are required as a result of implementing the proposed project. The City, as the CEQA lead agency, is responsible for monitoring the implementation of the adopted mitigation measures.

Air Quality

2-1 Prior to issuance of any construction permits, development project applicants shall prepare and submit to the City of Pasadena Planning Division a technical assessment evaluating potential project construction -related air quality impacts. The evaluation shall be prepared in conformance with South Coast Air Quality Management District (SCAQMD) methodology for assessing air quality impacts. If construction -related criteria air pollut ants are determined to have the potential to exceed the SCAQMD - adopted thresholds of significance, the City of Pasadena Planning Division shall require that applicants for new development projects incorporate mitigation measures to reduce air pollutant emi ssions during construction activities. These identified measures shall be incorporated into all appropriate construction documents (e.g., construction management plans) submitted to the City and shall be verified by the City’s Planning Division. Mitigation measures to reduce construction -related emissions include, but are not limited to:
• Requiring fugitive-dust control measures that exceed SCAQMD’s Rule 403, such as:
• Use of nontoxic soil stabilizers to reduce wind erosion. • Applying water every four hours to active soil-disturbing activities. • Tarping and/or maintaining a minimum of 24 inches of freeboard on trucks hauling dirt, sand, soil, or other loose materials.
• Using construction equipment rated by the United States Environmental Protection Agency as having Tier 3 (model year 2006 or newer) or Tier 4 (model year 2008 or newer) emission limits, applicable for engines between 50 and 750 horsepower. • Ensuring that construction equipment is properly serviced and maintained to the manufacturer’s standards.
• Limiting nonessential idling of construction equipment to no more than five consecutive minutes.
• Using Super -Compliant volatile organic compound ( VOC) paints for coating of architectural surfaces whenever possible. A list of Super -Compliant architectural coating manufactures can be found on the SCAQMD’s website at http://www.aqmd.gov/prdas/brochures/Super-Compliant_AIM.pdf.

2-2 Prior to future discretionary project approval, development project applicants shall prepare and submit to the City of Pasadena Planning Division a technical assessment evaluating potential project operation phase-related air quality impacts. The evaluation shall be prepared in conformance with SCAQMD methodology in assessing air quality impacts. If operation -related air pollutants are determined to have the potential to exceed the SCAQMD -adopted thresholds of significance, the City of Pasadena Planning Division shall require that applicants for new development projects incorporate mitigation measures to reduce air pollutant emissions during operational activities. The identified measures shall be included as part of the Standard Conditions of Approval. Below are possible mitigation measures to reduce long-term emissions:
• For site-specific development that requires refrigerated vehicles, the construction documents shall demonstrate an adequate number of electrical service connections at loading docks for plug-in of the anticipated number of refrigerated trailers to reduce idling time and emissions.
• Applicants for manufacturing and light industrial uses shall consider energy storage and combined heat and power in appropriate applications to optimize renewable energy generation systems and avoid peak energy use. • Site-specific developments with truck delivery and loading areas and truck parking spaces shall include signage as a reminder to limit idling of vehicles while parked for loading/unloading in accordance with California Air Resources Board Rule 2845 (13 California Code of Regulations Chapter 10 § 2485).
• Site-specific development shall demonstrate that an adequate number of electrical vehicle Level 2 charging stations are provided onsite. The location of the electrical outlets shall be specified on building plans, and proper installation shall be verified by the Building Division prior to issuance of a Certificate of Occupancy. • Applicant-provided appliances shall be Energy Star appliances (e.g., dishwashers, refrigerators, clothes washers, and dryers). Installation of Energy Star appliances shall be verified by the Building & Safety Division during plan check. • Applicants for future development projects along existing and planned transit routes shall coordinate with the City of Pasadena, Metro, and Foothill Transit to ensure that bus pads and shelters are incorporated, as appropriate.

2-3 Prior to future discretionary project approval, applicants for new industrial or warehousing land uses that 1) have the potential to generate 100 or more diesel truck trips per day or have 40 or more trucks with operating diesel -powered transport refrigeration units, and 2) are within 1,000 feet of a sensitive land use (e.g., residential, schools, hospitals, or nursing homes), as measured from the property line of the project to the property line of the nearest sensitive use, shall submit a health risk assessment (HRA) to the City of Pasadena Planning Division. The HRA shall be prepared in accordance with policies and procedures of the state Office of Environmental Health Hazard Assessment and the South Coast Air Quality Management District. If the HRA s hows that the incremental cancer risk and/or noncancer hazard index exceeds the respective thresholds, as established by the SCAQMD at the time a project is considered, the applicant will be required to identify and demonstrate that best available control technologies for toxics (T -BACTs), including appropriate enforcement mechanisms, are capable of reducing potential cancer and noncancer risks to an acceptable level. T-BACTs may include, but are not Chapter 4: Mitigation Measures North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

limited to, restricting idling onsite or electrifying warehousing docks to reduce diesel particulate matter, or requiring use of newer equipment and/or vehicles. T -BACTs identified in the HRA shall be identified as mitigation measures in the environmental document and/or incorporated into the site plan.

2-4 Prior to future discretionary approval, the City of Pasadena Planning Division shall evaluate new development proposals for sensitive land uses (e.g., residences, schools, and day care centers) within the City for potential incompatibilities with regard to the California Air Resources Board’s Air Quality and Land Use Handbook: A Community Health Perspective (April 2005). In addition, applicants for siting or expanding sensitive land uses that are within the recommended buffer distances listed in Table 1-1 of the California Air Resources Board ( CARB) Handbook shall submit a HRA to the City of Pasadena. The HRA shall be prepared in accordance with policies and procedures of the state Office of Environmental Health Hazard Assessment (OEHHA) and the SCAQMD. The latest OEHHA guidelines shall be used for t he analysis, including age sensitivity factors, breathing rates, and body weights appropriate for children. If the HRA shows that the incremental cancer risk and/or noncancer hazard index exceeds the respectiv e thresholds, as established by the SCAQMD at the time a project is considered, the applicant will be required to identify and demonstrate that mitigation measures are capable of reducing potential cancer and noncancer risks to an acceptable level (i.e., below the aforementioned thresholds as established by the SCAQMD), including appropriate enforcement mechanisms.

Measures to reduce risk may include but are not limited to:
• Air intakes oriented away from high-volume roadways and/or truck loading zones. • Heating, ventilation, and air conditioning systems of the buildings provided with appropriately sized maximum efficiency rating value (MERV) filters. • Heating, ventilation, and air conditioning systems for units that are installed with MERV filters shall maintain positive pressure within the building’s filtered ventilation system to reduce infiltration of unfiltered outdoor air.

Mitigation measures identified in the HRA shall be identified as mitigation measures in the environmental document and/or incorporated into the site development plan as a component of the proposed project. The air intake design and MERV filter requirements shall be noted and/or reflected on all building plans submitted to the City and shall be verified by the City’s Planning Division. The intent of this mitigation measure is to reflect current CARB and SCAQMD Guidance/Standards as well as CEQA legislation a nd case law, and the City implementation of the measure shall adhere to current standards/law at the time such analyses are undertaken.

2-5 Prior to future discretionary approval, if it is determined that a project has the potential to emit nuisance odors beyond the property line, an odor management plan shall be prepared by the project applicant, subject to review and approval by the Planning & Community Development Director or their designee. Facilities that have the potential to generate nuisance odors include but are not limited to:
• Wastewater treatment plants
• Composting, green waste, or recycling facilities
• Fiberglass manufacturing facilities
• Painting/coating operations
Chapter 4: Mitigation Measures North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 4 ends

• Large-capacity coffee roasters
• Food-processing facilities
The odor management plan shall show compliance with the South Coast Air Quality Management District’s Rule 402 for nuisance odors. The Odor Management Plan shall identify the T-BACTs that will be utilized to reduce potential odors to acceptable levels, including appropriate enforcement mechanisms. T -BACTs may include but are not limited to scrubbers (i.e., air pollution control devices) at the industrial facility. T-BACTs identified in the odor management plan shall be identified as mitigation measures in the environmental document and/or incorporated into the site plan.

Biological Resources

3-1 The City of Pasadena shall require applicants of future development projects that disturb undeveloped land in the San Rafael Hills and tract of land at the northwest intersection of Crestford Drive and Florecita Drive, to prepare a biological resources survey. The survey shall be conducted by a qualified biologist and shall be a reconnaissance level field survey of the project site for the presence and quality of biological resources potentially affected by project development. These resources include, but are not limited to, special status species or their habitat, sensitive habitats such as wetlands or riparian areas, and jurisdictional waters. If sensitive or protected biological resources are absent from the project site and adjacent lands potentiall y affected by the project, the biologist shall submit a written report substantiating such to the City of Pasadena before issuance of a grading permit by the City, and the project may proceed without any further biological investigation. If sensitive or pr otected biological resources are present on the project site or may be potentially affected by the project, implementation of Mitigation Measure 3-2 shall be required.

3-2 A qualified biologist shall evaluate impacts to sensitive or protected biological resources from development. The impact assessment may require focused surveys that determine absence or presence and distribution of biological resources on the site. These surveys may include but are not limited to: 1) focused special status animal surveys if suitable habitat is present; 2) appropriately timed focused special status plant surveys that will maximize detection and accurate identification of target plant species; and 3) a delineation of jurisdictional boundaries around potential wetlands, riparian habitat, and waters of the United States or State. The results of these surveys will assist in assessing actual project impacts, and with the development of project - specific mitigation measures. Alternatively, the project applicant may forgo focused plant and animal surveys and assume presence of special status species in all suitable habitats on the project site. The qualified biologist shall substantiate the impact evaluation or the assumed presence of special -status species in all suitable habitats onsite in a written report submitted to the City of Pasadena before issuance of a grading permit by the City.

3-3 The City of Pasadena shall require applicants of development project to avoid potential impacts to sensitive or protected biological resources to the greatest extent feasible.

Depending on the resources potentially present on the project site, avoidance m ay include: 1) establishing appropriate no-disturbance buffers around onsite or adjacent resources, and/or 2) initiating construction at a time when special status or protected animal species will not be vulnerable to project-related mortality (e.g., outside the avian nesting season or bat maternal or wintering roosting season). Consultation with Chapter 4: Mitigation Measures North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 4 ends

relevant regulatory agencies may be required in order to establish suitable buffer areas. If the project avoids all sensitive or protected biological resources, no further action is required. If avoidance of all significant impacts to sensitive or protecte d biological resources is not feasible, the project shall implement Mitigation Measure 3-

4. 3-4 The City of Pasadena shall require applicants to design development projects to minimize potential impacts to sensitive or protected biological resources to the greatest extent feasible, in consultation with a qualified biologist and/or appropriate regulatory agency staff. Minimization measures may include 1) exclusion and/or silt fencing, 2) relocation of impacted resources, 3) construction monitoring by a qualified biologist, and 4) an informative training program conducted by a qualified biologist for construction personnel on sensitive biological resources that may be impacted by project construction. If minimization of all significant impacts to sensitive or protected biological resources is infeasible, the project shall implement Mitigation Measure 3-5.

3-5 A qualified biologist will develop appropriate mitigations that will reduce project impacts to sensitive or protected biological resources to a less than significant level, if feasible. The type and amount of mitigation will depend on the resources impact ed, the extent of the impacts, and the quality of habitats to be impacted. Mitigations may include, but are not limited to: 1) compensation for lost habitat or waters in the form of preservation or creation of in-kind habitat or waters, either onsite or offsite, protected by conservation easement; 2) purchase of appropriate credits from an approved mitigation bank servicing the Pasadena area; and 3) payment of in-lieu fees.

3-6 Applicants of projects developed pursuant to the General Plan Update shall obtain appropriate permit authorization(s) for impacts to jurisdictional waters, wetlands, and/or riparian habitats. The types of permits potentially required for impacts to jurisdictional waters are a Clean Water Act (Section 404) permit issued by the US Army Corps of Engineers, a California Water Certificate or Waste Discharge Order issued by the Regional Water Quality Control Board, and a Stream Alteration Agreement issued by the California Department of Fish and Wildlife.

Cultural Resources

4-1 If cultural resources are discovered during construction of land development projects in Pasadena that may be eligible for listing in the California Register for Historic Resources, all ground disturbing activities in the immediate vicinity of the find shall be halted until the find is evaluated by a Registered Professional Archaeologist. If testing determines that significance criteria are met, then the project shall be required to perform data recovery, professional identification, radiocarbon dates a s applicable, and other special studies; and provide a comprehensive final report including site record to the City and the South Central Coastal Information Center at California State University Fullerton. No further grading shall occur in the area of the discovery until Planning Department approves the report.

4-2 The City shall require applicants for development permits that involve grading in areas within the paleontologically sensitive Topanga formation to provide studies by a qualified paleontologist assessing the sensitivity of the project for buried paleontological resources. On properties determined to be moderately to highly sensitive for paleontological resources, such studies shall provide a detailed mitigation Chapter 4: Mitigation Measures North Lake Specific Plan Update

Addendum to the Pasadena General Plan EIR September 2025

Page 4 ends

plan, including a monitoring program and recovery and/or in situ preservation plan, based on the recommendations of a qualified paleontologist. The mitigation plan shall include the following requirements:
• A paleontologist shall be retained for the project and will be on call during grading and other significant ground -disturbing activities more than six feet below the ground surface.
• Should any potentially significant fossil resources be discovered, no further grading shall occur in the area of the discovery until the Planning and Community Development Director concurs in writing that adequate provisions are in place to protect any significant resources. Work may continue outside a minimum radius of 25 feet from the discovery pending review by the Director. • Unanticipated discoveries shall be evaluated for significance by a qualified paleontologist. If evaluation determines that significance criteria are met, then the project shall be required to perform data recovery, professional identification, radiocarbon dates as applicable, and other special studies; and provide a comprehensive final report, including catalog with museum numbers.

Greenhouse Gas Emissions
5-1 Within approximately 18 months of adoption of the proposed General Plan Update, the City of Pasadena shall prepare and present to the City Council for adoption a community climate action plan/greenhouse gas reduction plan. The Plan shall identify strategies to be implemented to reduce GHG emissions associated with the City and shall include as one alternative a program that achieves the AB 32 targets. In addition, the City shall monitor GHG emissions by updating its community-wide GHG emissions inventory every five years upon adoption of the initial Plan. Upon the next update to the community climate action plan/greenhouse gas reduction plan, the inventory, GHG reduction measures, and GHG reductions shall be forecast to year 2035 to ensure progress toward achieving the interim target that aligns with the long -term GHG reduction goals of Executive Order S-03-04. The Plan update shall take into account the reductions achievable from federal and state actions and measures as well as ongoing work by the City and the private sector. The 2035 Plan update shall be completed by January 1, 2021, with a plan to achieve GHG reductions for 2035 or 2040, provided the state has an actual plan to achieve reductions for 2035 or 2040.

New reduction programs in similar sect ors as the proposed Plan (building energy, transportation, waste, water, wastewater, agriculture, and others) will likely be necessary. Future targets shall be considered in alignment with state reduction targets, to the maximum extent feasible, but it is premature at this time to determine whether or not such targets can be feasibly met through the combination of federal, state, and local action given technical, logistical and financial constraints. Future updates to the community climate action plan/greenhouse gas reduction plan shall account for the horizon beyond 2035 as the state adopts actual plans to meet post - 2035 targets. In all instances, the community climate action plan/greenhouse gas reduction plan and any updates shall be consistent with state and federal law.

The study shall be prepared by an acoustical engineer and be submitted to the City of Pasadena Planning Division. The study shall evaluate the vibration levels associated with operation of project-related equipment and activities experienced by nearby sensitive receptors. If it is determined that vibration impacts to nearby receptors exceed the Federal Transit Administration (FTA) vibration -annoyance criterion, the study shall recommend and the applicant shall implement the identified measures with the purpose of reducing vibration impacts to a less than significant level. The City of Pasadena shall verify implementation of all identified measures.
9-2 Prior to issuance of building permits for the new construction of habitable area, applicants for development projects shall adhere to the appropriate Vibration Category 2 and Vibration Category 3 screening distances for light rail transit as recommended in Table 9-2 of FTA’s Transit Noise and Vibration Impact Assessment (FTA 2006) in evaluating vibration impacts related to trains on the Metro Gold Line. Applicants for development projects that fall within the screening distances shall prepare and submit to the City of Pasadena Planning Division a study evaluating vibration impacts to the proposed development from train operations. The study shall be prepared by an acoustical engineer who shall identify measures to reduce impacts to habitable structures to below the FTA vibration annoyance criterion. The identified measures shall be incorporated into all design plans submitted to the City of Pasadena.

9-3 Prior to issuance of any grading and construction permits, applicants for individual projects that involve vibration -intensive construction activities, such as pile drivers, jack hammers, and vibratory rollers, within 25 feet of sensitive receptors (e.g., residences and historic structures) shall prepare and submit to the City of Pasadena Planning Division a study to evaluate potential construction -related vibration impacts. The study shall be prepared by an acoustical engineer and shall identify measures to reduce impacts to habitable structures to below the FTA vibration annoyance criterion. If construction-related vibration is determined to be perceptible at vibration-sensitive uses, additional requirements, such as use of less -vibration- intensive equ ipment or construction technique, shall be implemented during construction (e.g., drilled piles, static rollers, and nonexplosive rock blasting). Identified measures shall be included on all construction and building documents and submitted for verification to the City of Pasadena Planning Division.

9-4 Prior to issuance of any construction permits, applicants for individual projects that involve vibration-intensive construction activities, such as pile drivers, jack hammers, bulldozers, and vibratory rollers, within 25 feet of sensitive receptors (e.g., residences) or 50 feet of historic structures, shall prepare and submit to the City of Pasadena Planning Division a study to evaluate potential construction-related vibration impacts.

The vibration assessment shall be prepared by an acoustical engineer and be based on the FTA vibration-induced architectural damage criterion. If the study determines a potential exceedance of the FTA thresholds, measures shall be identified that ensure vibration levels are reduced to below the thresholds. Measures to redu ce vibration levels can include use of less -vibration-intensive equipment (e.g., drilled piles and static rollers) and/or construction techniques (e.g., nonexplosive rock blasting and use Chapter 4: Mitigation Measures North Lake Specific Plan Update

of hand tools) and preparation of a preconstruction survey report to assess the condition of the affected sensitive structure. Notwithstanding the above, pile drivers shall not be allowed within 150 feet of any historic structures. Identified measures shall be included on all construction and building documents and submitted for verification to the City of Pasadena Planning Division.

9-5 Prior to issuance of construction permits, applicants for new development projects within 500 feet of noise -sensitive receptors shall implement the following best management practices to reduce construction noise levels:
• Consider the installation of temporary sound barriers for construction activities immediately adjacent to occupied noise-sensitive structures. • Equip construction equipment with mufflers.
• Restrict haul routes and construction-related traffic. • Reduce nonessential idling of construction equipment to no more than five minutes.

The identified best management practices shall be noted on all site plans and/or construction management plans and submitted for verification to the City of Pasadena Planning Division.

Transportation and Traffic

13-1 The City of Pasadena shall update its existing transportation impact fee program by 2020. The City shall prepare a “Nexus” Study that will serve as the basis for requiring development impact fees under AB 1600 legislation, as codified by California Code Government Section 66000 et seq. The established procedures under AB 1600 require that a “reasonable relationship” or nexus exist between the traffic improvements and facilities required to mitigate the traffic impacts of new development pursuant to the proposed project. After approval of the Nexus Study, the City shall update the transportation impact fee program to fund all citywide circulation improvements, including the pedestrian and bicycle network. The fee program shall stipulate that fees are ass essed when there is new construction or when there is an increase in square footage within an existing building or the conversion of existing square footage to a more intensive use. Fees are calculated by multiplying the proposed square footage or dwelling unit by the rate identified. The fees are included with any other applicable fees payable at the time the building permit is issued. The City will use the development fees to fund construction (or to recoup fees advanced to fund construction).
