PROJECT LOCATION: The Pasadena Non-Potable Water Project is located within the San Gabriel Valley, approximately 10 miles northeast of downtown Los Angeles in Los Angeles County, California. The Study Area includes portions of PWP’s service area and areas outside of PWP’s service area within unincorporated areas of Los Angeles County, La Cañada Flintridge, San Marino, and Glendale.
PROJECT DESCRIPTION: The purpose of the Pasadena Non-Potable Water Project is to meet a portion of PWP’s non-potable water needs using local water sources. The proposed Project involves construction and operation of a new non-potable water distribution system to deliver water from three local supply sources: (1) recycled water produced by the Los Angeles/Glendale Water Reclamation Plant (“LAG”), (2) surface water inflows from two existing tunnels (Devils Gate and Richardson Springs), and (3) water from the Arroyo Seco stream, to customers within the service areas of PWP, Lincoln Avenue Water Company, Foothill Municipal Water District, and California American Water Company, for landscape irrigation, industrial cooling, and other non-potable uses. The three water supplies included in the proposed Project (recycled water, tunnel water, and raw surface water) are collectively referred to as “non-potable water supplies”. Figure 1 , attached to this document, shows an overview of the project study area and the three non-potable water supplies.
Tunnel water and Arroyo Seco water are variable and may not be available for extended periods of time; when those two supplies are not available, the entire non-potable demand would be met with recycled water from LAG. Table 1 shows the estimated volumes of water from each source.

I of the proposed Project would deliver approximately 700 AFY of non-potable water to four Pasadena customers in the area around the Rose Bowl Stadium; the build-out would supply approximately 3,060 AFY of non-potable water to 46 customers for landscape irrigation, cooling and other non-potable uses. As part of the proposed Project, the City of Pasadena would adopt mandatory use ordinances or approve user agreements whereby these customers and others would become obligated to, or commit to, meet an appropriate portion of their non-potable water needs through water supplied by the proposed Project.
The primary and most reliable source of non-potable water is up to 5.4 million gallons per day (“MGD”) tertiary treated recycled water from LAG. LAG is located approximately 6 miles west of Pasadena in the City of Los Angeles and is operated by the City of Los Angeles Bureau of Sanitation. The proposed Project will connect to the Glendale Water and Power (“Glendale”) existing recycled water system at Scholl Canyon. Three new pumping units will be installed in the existing Glendale and LAG pump stations to pump recycled water from LAG to the top of Scholl Canyon, in the City of Glendale. At Scholl Canyon the recycled water will be stored in the proposed Scholl Canyon Recycled Water Reservoir. From the reservoir, the non-potable water will be distributed to users through new dedicated pipelines. A new pressure reducing station will be constructed downhill of the Scholl Canyon Reservoir, in Pasadena at the corner of Washington Boulevard and West Drive to reduce the water pressure. At the same location two other facilities will be constructed: a new pump station to deliver water to the Brookside Golf Course irrigation system and a new hydroelectric generation turbine facility to produce energy from the recycled water.
Up to 430 AFY (about 14%) of the non-potable supply for the project will come from two existing tunnels (Devils Gate and Richardson Springs) that collect subsurface water, which currently drains into the Arroyo Seco Channel. Tunnel water will be pumped into the non- potable system and distributed to customers.
The third non-potable water source, raw Arroyo Seco surface water, originates primarily as rain and snow runoff from the mountains. This source could provide up to 1,180 AFY (about 39%) of the non-potable supply to the project. If available, excess raw Arroyo Seco surface water, currently used to recharge groundwater at the Arroyo Seco spreading grounds, could be captured, pumped into the non-potable system and distributed to customers.
The Pasadena Non-Potable Water Project will be implemented in six major construction phases. As PWP implements each phase after Phase I, more pumping capacity will be required within the Glendale’s system to deliver recycled water to Pasadena. The necessary pumping upgrades would be made within Glendale’s existing pump buildings. New pipelines would be installed primarily under public streets in existing or new rights-of-ways or easements. Construction is anticipated to be completed over a ten-year period.
At various locations along the construction routes, staging areas would be designated to store pipe, construction equipment, and other construction-related material. The staging areas would be located along the routes where space is available, such as vacant lots, roadway turnouts, and parking lots. Typical construction activities include site preparation,

This extension includes pipelines only.
This EIR will address Phase I at a project level and future system extensions at a program level, and will allow PWP to consider the cumulative environmental impacts of full build-out of the Project, and to comply with CEQA and NEPA during construction of Phase I. Additional project-level environmental review would be required prior to approval of the future extensions. POTENTIAL ENVIRONMENTAL EFFECTS: An EIR will be prepared to evaluate the proposed Project's potential environmental impacts and analyze project alternatives. The topic areas anticipated to be discussed in the EIR are listed and checkmarked in the following table and described further below. The EIR will be prepared in compliance with NEPA requirements, because of potential federal funding opportunities. Accordingly, topic areas specific to NEPA, such as Environmental Justice, will also be evaluated with respect to the proposed Project.

PASADENA NON -POTABLE WATER PROJECT NOTICE OF PREPARATION AND SCOPING MEETINGS
Aesthetics – The proposed Project will be analyzed to determine if it would have an adverse impact on scenic vistas, degrade the existing visual character or quality of the site and its surroundings, or create any new sources of light or glare. It is anticipated that new non- potable water facilities would generally integrate with the existing surroundings; however, in some instances their installation would potentially alter the visual character of the site and the need for visual screening or other mitigation measures will be considered.
Agricultural Resources – The proposed Project is not expected to impact farmland, conflict with zoning for agricultural use, forest or timberland, or Williamson Act contracts, or result in the loss of forest land. Air Quality – The proposed Project will be analyzed as compared to applicable air quality plans and its potential to violate air standards or contribute to existing violations, increase criteria pollutants, expose sensitive receptors, and generate odors. Potential air quality impacts from the proposed Project would primarily relate to construction-related emissions and odors. Biological Resources – The proposed Project will be analyzed for its potential effects on sensitive or special status species, riparian habitat or natural communities identified by the California Department of Fish and Wildlife or U.S. Fish and Wildlife, wetlands, or migration of species; and local policies and conservation plans protecting biological resources will be reviewed to determine if conflicts are present. Anticipated impacts to biological resources include impacts to: special status plant and wildlife species north of the Art Center College of Design, Arroyo Seco stream, and pipeline alignments (tree impacts). The need for mitigation measures to reduce impacts to protected species will be considered, such as focused monitoring surveys, restrictions on construction schedules during nesting seasons, a tree inventory and tree protection measures.
Cultural Resources – The proposed Project will be analyzed to determine if it would have any substantial, adverse changes in the significance of historic or archaeological resources; directly or indirectly destroy a unique cultural resources feature; or disturb any human remains. Anticipated impacts to cultural resources include potential changes to the significance of two historic districts (Pasadena Arroyo Parks and Recreation District and the Arroyo Seco Flood Control Channel District), and impacts to currently unknown archaeological and paleontological resources. The need for mitigation measures will be considered, such as compliance with standards for rehabilitation, focused assessments for future extensions, and monitoring and construction restrictions.
Geology and Soils – The proposed Project will be analyzed to determine if it would expose people or structures to substantial adverse effects through seismic movement, shaking, landslides, or liquefaction; result in substantial erosion, be located on an unstable or expansive soil, or have soils incapable of infiltration if required for wastewater disposal. The proposed Project could potentially be impacted by seismic activity; therefore additional geologic assessment for potentially affected facilities is anticipated.
Greenhouse Gas Emissions – The proposed Project will be analyzed to determine if it would result in an increase in greenhouse gas emissions compared to existing conditions or
Page 6 of 8
PASADENA NON -POTABLE WATER PROJECT NOTICE OF PREPARATION AND SCOPING MEETINGS
conflict with plans or policies adopted for the purpose of reducing greenhouse gas emissions. Greenhouse gas emissions from the proposed Project (both temporary and long-term) would likely occur due to the construction and operation of non-potable water facilities associated with the proposed Project. Full build-out of the proposed Project is anticipated to align with provisions of the City of Pasadena’s Green City Action Plan which calls for expanding the use of recycled water.
Hazards and Hazardous Materials – The proposed Project will be analyzed to determine impacts to the public or environment (including nearby schools) from the transport, use or encounter of hazardous substances; analysis of special safety hazards near airports or airstrip; review of potential interference with emergency response plans; and review of exposure to wildfires. The proposed Project is required to comply with applicable standards that regulate hazardous materials, which would reduce the potential for significant impacts related to hazardous materials. Regardless, the need for mitigation measures will be considered, such as actions for possible contamination encounters, access strategies, and fire prevention measures.
Hydrology and Water Quality – The proposed Project will be analyzed to determine impacts to water quality, waste discharge requirements, water supplies, drainage patterns, and increased exposure to flood hazards and inundation. Diversion of tunnel water and surface water flows for beneficial reuse could potentially reduce downstream flows in the Arroyo Seco channel and Lower Arroyo Stream Restoration Project; these potential impacts will be analyzed and potentially addressed through development of a water balance model.
Land Use and Planning – The proposed Project is not expected to physically divide an established community, or conflict with applicable land use or conservation plans.
Mineral Resources – The proposed Project is not expected to result in the loss of mineral resources.
Noise – The proposed Project will be analyzed to determine if it would result in exposure of persons to excessive noise or ground vibrations, either temporary or overall increases in ambient noise levels. Potential noise and vibration impacts are anticipated and the need for mitigation including noise control measures and preconstruction noticing will be considered.
Population and Housing – The proposed Project is not expected to induce population growth, or displace housing or people.
Public Services – The proposed Project will be analyzed to determine if it would result in impacts to government facilities or otherwise impact public services such as fire or police protection, schools, parks, or other public facilities.
Recreation – The proposed Project will be analyzed to determine if it would increase the use of existing neighborhood or regional park facilities that would accelerate deterioration of the facility, or require construction of a facility that would adversely impact the environment, or conflict with established recreational uses of the area. The proposed Project is not anticipated
Page 7 of 8
PASADENA NON -POTABLE WATER PROJECT NOTICE OF PREPARATION AND SCOPING MEETINGS
to increase the demand for or require construction or expansion of recreational facilities; however, use of facilities may be temporarily disrupted due to construction activities. Transportation/Traffic – The proposed Project will be analyzed to determine if it would cause an increase in traffic (temporary or long-term), result in a change in air traffic patterns, increase hazards due to a design feature, result in inadequate emergency access or parking capacity, or conflict with plans or policies supporting alternative transportation. Temporary impacts to transportation/traffic are anticipated due to construction activities and a contractor- led traffic management plan is planned.
Utilities and Service Systems – The proposed Project will be analyzed to determine if it would exceed regulatory wastewater treatment requirements; require new or expanded wastewater or stormwater facilities; have sufficient water supply entitlements, sufficient treatment capacity, and disposal facilities; comply with solid waste regulations, and result in disruption of utilities.
Environmental Justice – The proposed Project will be analyzed to determine if it would disproportionately impact minority or low-income populations.
Mandatory Findings of Significance – The proposed Project will be analyzed in the appropriate sections, above, to determine if it would degrade the quality of the environment including species reduction or adverse effects on human beings, or have impacts that are cumulatively considerable in combination with other projects (current or future). The need to implement mitigation measures to address such impacts will be considered as part of the analysis.
