6. Climate Risk Detailed Report
6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.
Climate Hazard Result for Project Location Unit
Temperature and Extreme Heat 6.82 annual days of extreme heat Extreme Precipitation 4.00 annual days with precipitation above 20 mm Sea Level Rise — meters of inundation depth
Wildfire 0.00 annual hectares burned
Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.
Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.
Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Core Structure, Inc., 23172 Plaza Pointe Dr., Suite 145, Laguna Hills, CA 92653 949-954-7244 I. Introduction
The project consists of the design and construction of eight new single family houses for BHT Temple Venture, LLC at 2671 Bayshore Dr, Newport Beach, CA 91384. No Infrastructure will be transferred to Public Agencies. No known Significant Ecological Area (SEA).
A. Project Description
The proposed development will drain to underground Cudo to infiltrate.
The proposed project site is approximately 0.598-acres without dedication, with 0.197 acres of impervious area, and 0.401 acres of pervious area.
Total Area = 26,061 SF = 0.598 acres
Building Area = 10,448 SF
Hardscape Area = 1,134 SF
Gravel Driveway = 6,840 SF
Landscape Area = 7,639 SF
This project is a Large-Scale Designated Project, as defined by the County of Los Angeles Department of Public Works low Impact Development Standards Manual, dated February 2014 for the following reasons:
Large-Scale Non-Designated Projects – all residential development and redevelopment of five units or greater and all non-residential development or redevelopment. • Where 50 percent or more of the impervious surface of a previously developed site is proposed to be altered and the previous development project was not subject to post-construction stormwater quality control measures, the entire development site (e.g., both the existing development and the proposed alteration) must meet the requirements of the LID Standards Manual.
• Where less than 50 percent of the impervious surface of a previously developed site is proposed to be altered and the previous development project was not subject to post-construction stormwater quality control measures, only the proposed alteration must meet the requirements of the LID Standards Manual.
B. Drainage Characteristics
The drainage area of the project site is approximately 0.598 acres. The area is on a sloped ground. The area is sloping from north toward the south direction. The drainage area is composed of building, driveway, parking and Landscaping. The existing run off is draining towards to south direction from north direction.
With the construction of building & driveway, the proposed drainage system of the area is described as follows:
All of storm water at the front yard, back yard, side yard and driveway will be collected by area drains. All storm water will go through the drain in the landscaping and then through the CUDO system. If the CUDO system is full, stromwater will overflow from the southeast corner catch basin to the street via parkway drain.
Core Structure, Inc., 23172 Plaza Pointe Dr., Suite 145, Laguna Hills, CA 92653 949-954-7244 C. Pollutants of Concerns
Pollutants of concern include trash and dried leaves, twigs from the trees and shrubs, silt, pesticides and fertilizers in the planter areas.
II. Best Management Practices (BMPs)
The following is a list of all BMPs to be implemented on site:
A. Structural BMPs
1. Kristar FloGard Catch Basin Filter Insert
Kristar Trench Dain Filter Insert, by Kristar Enterprises, Inc. which will be installed in trench drain, are being proposed as structural BMPs for the removal of silt and debris in storm water runoff.
The filter inserts have been selected to accommodate, up to and including, the 85th percentile storm event.
2. Cudo System
The project will propose to install a cudo system to treat stromwater.
B. Non-structural BMPs
1 Open paved areas and planter areas
a. Regular sweeping of all open and planter areas, at a minimum, on a weekly basis in order to prevent dispersal of pollutants that may collect those surfaces. b. Regular pruning of trees and shrubs in the planter areas to avoid formation of dried leaves and twigs, which are normally blown by the wind during windy days. These dried leaves are likely to clog the surface inlets of the drainage system when rain comes, which would result to flooding of the surrounding area due to reduced flow capacities of the inlets. c. Trash and recycling containers shall be used such that, If they are to be located outside or apart from the principal structure, are fully enclosed and watertight in order to prevent contact of storm water with waste matter, which can be a potential source of bacteria and other pollutants in runoff. These containers shall be emptied and wastes disposed of properly on a regular basis.
2. Education and Training
The owner shall be made aware of the structural BMPs installed in the project. Information materials, such as brochures, shall also be provided for their complete information. The Owner shall also be briefed about chemical management and proper methods of handling and disposal of wastes and should understand the on-site BMPs and their maintenance requirements.
3. Landscaping
Minimize the use of pesticides and fertilizers to the maximum extent practical.
4. Monitoring and Maintenance
a. All BMPs shall be operated, monitored, and maintained for the life of the project and at a minimum, all structural BMPs shall be inspected, cleaned-out, and where necessary, repaired, at Core Structure, Inc., 23172 Plaza Pointe Dr., Suite 145, Laguna Hills, CA 92653 949-954-7244 the following minimum frequencies: 1) prior to October 15th each year; 2) during each month between October 15th and April 15th of each year and, 3) at least twice during the dry season (between April 16 and October 14 of each year).
b. Debris and other water pollutants removed from structural BMPs during cleanout shall be contained and disposed of in a proper manner
c. The drainage system and associated structures and BMPs shall be maintained according to manufacturer’s specification to ensure maximum pollutant removal efficiencies.

(Underground Retention / Detention / Infiltration /
Water Reuse Systems)
CUDO® CUBES
Description / Basic Function
CUDO is a modular stormwater system comprised of a grouping of modular polypropylene or concrete cubes that when constructed form an underground storage area for stormwater. This system can be used for infiltration, retention, detention or water reuse. CUDO can help achieve runoff detainment and storage to help attenuate the peak flow to pre-construction levels and can help conform to current Low Impact Development requirements.
Infiltration
The purpose of a CUDO infiltration system is to capture stormwater runoff, store the runoff, and then allow it to percolate into the ground via the open space area of the cubes and perforations in the side wall. The system is backfilled with a Class I material defined by ASTM D2321 as a cleaned open graded rock or a Class II permeable sand. The rock or sand provide additional storage capacity but also allow for a percolation interface with the native material. The ground water is “recharged” with this type of system.
Detention
The purpose of a CUDO detention system is to capture stormwater runoff, store the runoff, and then allow it to be released at a controlled rate through an appropriately sized orifice control. A detention system helps attenuate the peak flow from the site assuring that pre-development runoff flows are not exceeded as a result of the development. A CUDO detention requires the cubes to be encapsulated with an impermeable liner for the polypropylene system or the seams of the concrete system to be sealed with a water proof mastic.
Retention
A CUDO retention system is a hybrid system. It is a combination of a detention system and an infiltration system. A retention system is utilized to attenuate peak flow as well as promote groundwater re-charge. A retention system is outfitted with an overflow pipe at the top of the system which allows the system to fill for infiltration but also outlet if the ground is saturated.
Water Reuse
The purpose of a water-reuse CUDO system is to capture and store water for future use. The system is constructed in a similar fashion to a detention system but instead of a controlled outlet the system is constructed with an emergency overflow. A water reuse system is a Low-Impact Development (LID) device that helps attenuate peak flows as well as conserve water. Water may be reused through an active pump system or passive irrigation.
Inspection/Cleanout Ports
Inspection and cleanout ports are 18-inch diameter vertical risers connected to the uppermost polypropylene CUDO cubes or up to 30-inch manhole access connected to the concrete CUDO. They are used for entrance into the system, or for access to place vacuum truck hoses or water-jetting devices or CCTV equipment. Ports are strategically located near inlet and outlet pipes and in other areas or probable deposition in the system. It is recommended to keep surface level access lids sealed and bolted at all times when the system is in service.
Inlet Bay
Some systems are configured so that pretreatment of the stormwater occurs within the CUDO system. In this case, the CUDO system will house an inlet bay. The inlet bay is separated from the rest of the CUDO system by sidewall plugs and is intended to separate gross pollutants, trash and debris and floatables from the CUDO system and pretreatment device. The bay contains its own sump area and unique access ports.

Maintenance Overview for CUDO
State and Local regulations require that stormwater storage systems be maintained and serviced on a recurring basis.
The purpose of maintaining a clean and obstruction free CUDO system is to ensure the system performs the intended function of the primary design. Trash and debris, floatables, gross pollutants and sediment can build up in the CUDO leading to clogging of the native soil interface or blockage of the inlet or outlet pipes. This can cause the system to function improperly by limiting storage volume, limiting the design percolation rates or impeding flow in and out of the system. Downstream and upstream, areas could run the risk of flooding and deleterious environmental impact.
Recommended Frequency of Service
It is recommended that the CUDO stormwater systems be serviced on a regularly occurring basis. Ultimately the frequency depends on the amount of runoff, pollutant loading, and interference from trash, debris and gross pollutants as well as proper maintenance of upstream pretreatment devices. However, it is recommended that each installation be inspected at least two times per year to assess service needs.
Recommended Timing of Service
Guidelines for the timing of service are as follows:
1. For areas with a definite rainy season the system should be serviced prior to and following the rainy season.
2. For areas subject to year-round rainfall service should occur on a regularly occurring basis. (A minimum of two times per year.)
3. For areas with winter snow and summer rain the system should be serviced prior to and after the snow season.
4. For installed devices that are subject to dry weather flows only (i.e. wash racks, parking garages, etc…) the unit should be serviced on a regularly occurring basis. (A minimum of two times per year.) Inspection
An inspection should be performed when the system is new. This allows the owner to establish a baseline condition for comparison to future inspections. Sediment build up can typically be monitored without entering the system. (No confined space entry.) Initial and subsequent inspection data should be recorded and filed for reference. Some regulatory agencies require that the results of the inspections be documented and reported. Inspection reports should comply with regulatory requirements and be submitted as required.
Inspection Procedures
5. Locate the inspection, cleanout and access ports. Inspection and cleanout ports are typically 18-inch diameter.
Access ports are typically 24-inch or 30-inch diameter. Pictures should be taken to document the location or a site map should be generated to detail the as-built locations of the ports.
6. Unbolt and remove the access port lids.
7. Insert a measuring device into the opening making note of a point of reference to determine the quantity of sediment and other accumulated material. If access is required to measure, ensure only certified confined space entry personnel having appropriate equipment are allowed to enter the system.
8. In addition, for accessible concrete CUDO systems personnel should utilize appropriate confined space entry procedures to enter the system and photograph its condition.
9. Inspect inlet and outlet locations for obstructions. Obstructions should be removed at this time.
10. Inspect the structural components of the system.
11. Fill in the CUDO Inspection/Maintenance Data Sheet and send a copy to the regulatory agency if necessary.
Disinfection of Water Reuse System
Periodic disinfection of water held for reuse may be required to abate bacteria and algae growth. This may be done using calcium hypochlorite tablets or by the addition of an ozone generator in a small recirculation system. 4 Maintenance
Cleanout of the CUDO system should be considered if there is sediment buildup of two or more inches at over 50% of the inspection ports. Cleaning shall be performed if sediment buildup is two inches or more over 75% of the system floor. In the event of a spill of a foreign substance, cleanout of the system should be considered.
Maintenance Procedures
1. Locate the inspection, cleanout and access ports. Inspection and cleanout ports are typically 18-inch diameter. Access ports are typically 24-inch or 30-inch diameter. Pictures should be taken to document the location or a site map should be generated to detail the as-built locations of the ports.
2. Unbolt and remove the access port lids.
3. Measure the sediment buildup at each port. If access is required to measure ensure only certified confined space entry personnel having appropriate equipment are allowed to enter the system.
4. A thorough cleaning of the system (inlets, outlets, ports, and inlet bays) shall be performed by either a vacuum truck or by manual methods.
5. Inspect inlet and outlet locations for obstructions. Obstructions should be removed at this time.
6. Inspect the structural components of the system.
7. Fill in the CUDO Inspection/Maintenance Data Sheet and send a copy to the regulatory agency if necessary.
Inspection / Maintenance Requirements
Below are some recommendations for equipment and training of personnel to inspect and maintain a CUDO system.
Personnel: OSHA Confined Space Entry Training is a prerequisite for entrance into a system. In the state of California personnel should be CalOSHA certified.
Equipment: Record Taking (pen, paper, voice recorder)
Proper Clothing (appropriate footwear, gloves, hardhat, safety glasses, etc.) Flashlight
Tape Measure
Measuring Stick
Pry Bar
Traffic Control (flagging, barricades, signage, cones, etc.) First Aid Materials
Debris and Contaminant Containers
Vacuum Truck
Disposal of Gross Pollutants, Hydrocarbons, and Sediment The collected gross pollutants, hydrocarbons, and sediment shall be offloaded from the vacuum truck into DOT approved containers for disposal. Once in the container the maintenance contractor has possession and is responsible for disposal in accordance with local, state and federal agency requirements.
Note: As the generator, the landowner is ultimately responsible for the proper disposal of the collected materials.
Because the material likely contains petroleum hydrocarbons, heavy metals, and other harmful pollutants, the materials must be treated as EPA class 2 Hazardous Waste. Proper disposal is required. www.oldcastlestormwater.com

Mitigation Measure HAZ-1: Soil Management Plan states, “A Soil Management Plan shall be developed in consultation with the appropriate regulatory authorities and the remedial action agreed action shall be completed.” A SMP alone cannot sufficiently identify and document the potential contaminants that may pose a threat to human health and the environment. DTSC recommends that a cleanup plan, a Removal Action Workplan (RAW) or Remedial Action Plan (RAP), be prepared to adequately address all site impacts after complete characterization.
Comments made on Mitigation measures - RAP or RAW to be used instead of SMP. Signal Hill Development plan states that a soil management plan be developed. This soil management plan is a blanket term used to describe actions associated with any potential remediaion. MM HAZ-1 Notes that " A Soil Management Plan shall be developed in consultation with the appropriate regulatory authorities and the remedial action agreed upon shall be completed. Work shall not resume in the affected area until appropriate actions have been implemented in accordance with the remediation plan." The mitigation measure will be futher clarified to include the SMP and RAP process and applicable oversight agency.
3.10.2 - MM HAZ-1: MM HAZ-1: Soil Management Plan and Remedial Action Plan.
Prior to initiating any ground disturbing activities on the Project Site, the project applicant shall prepare a Soil Management Plan (SMP) that is submitted to and reviewed and approved by the California Department of Toxic Substances Control (DTSC), the Los Angeles Regional Water Quality Control Board (LARWQCB), the Los Angeles County Fire Department (LACFD) Site Mitigation Unit (SMU), or other applicable regulatory agency having jurisdiction to review or approve the SMP. The SMP shall be prepared by a Registered Environmental Assessor or other qualified expert, and shall address the findings previous site investigations and radiation actions conducted at the site, and/or subsequent relevant studies. During construction, the contractor shall implement the SMP. If unidentified or suspected contaminated soil or groundwater evidenced by stained soil, noxious odors, or other factors, is encountered during site preparation or construction activities on any portion of the Project Site, work shall stop in the excavation area of potential contamination. Upon discovery of suspect soils or groundwater, the contractor shall notify the applicable regulatory agency, and retain a Registered Environmental Assessor or other qualified professional to collect soil samples to confirm the type and extend of contamination that may be present.
If contamination is confirmed to be present, any further ground disturbing activities within areas of identified or suspected contamination shall be conducted according to a site-specific Remedial Action Plan (RAP), prepared by a qualified professional. The contractor shall follow all procedural direction given by the applicable regulatory agency, and in accordance with the RAP to ensure that suspect soils are isolated, protected from runoff, and disposed of in accordance with transport laws and the requirements of the licensed receiving facility. If contaminated soil or groundwater is encountered and identified constituents exceed human health risk levels, ground disturbing activities shall not recommence within the contaminated areas until remediation is complete and a “no further action” letter is obtained from the appropriate regulatory agency or direction is otherwise given from the appropriate regulatory agency for a course of action that would allow that construction to recommence within any such areas. The project applicant shall submit the “no further action” letter or notification documenting direction from the regulatory agency to the City prior to resumption of any ground disturbing activity on the relevant portion of the Project Site. If compounds in soil are identified in concentrations that trigger SCAQMD’s Rules 1166 or 1466, the SMP will require compliance with such rules.

The City of Signal Hill and the South Coast Air Quality Management District are indicated as appropriate reporting agencies but are not recognized as appropriate oversight. Consultation should occur with proper oversight therefore, DTSC recommends the City of Signal Hill enter into a voluntary agreement to address contamination at brownfields and other types of properties or receive oversight from a self-certified local agency, DTSC or the Regional Water Quality Control Board. If entering into one of DTSC’s voluntary agreements, please note that DTSC uses a single standard Request for Lead Agency Oversight Application for all agreement types. Please apply for DTSC oversight using this link: Request for Agency Oversight Application. Submittal of the online application includes an agreement to pay costs incurred during agreement preparation. If you have any questions about the application portal, please contact your Regional Brownfield Coordinator.
At this time no remedial action will be required and therefore no oversite will be necessary. In the event of identified soil needing remediation consultation would occur with the DTSC, RWQCB, or a self-certified local agency (Los Angeles County).
Addressed in previous comment, see directly above.

DTSC recommends that all imported soil and fill material should be tested to assess any contaminants of concern meet screening levels as outlined in DTSC's Preliminary Endangerment Assessment (PEA) Guidance Manual. Additionally, DTSC advises referencing the DTSC Information Advisory Clean Imported Fill Material Fact Sheet if importing fill is necessary. To minimize the possibility of introducing contaminated soil and fill material there should be documentation of the origins of the soil or fill material and, if applicable, sampling be conducted to ensure that the imported soil and fill material are suitable for the intended land use. The soil sampling should include analysis based on the source of the fill and knowledge of the prior land use. Additional information can be found by visiting DTSC’s Human and Ecological Risk Office (HERO) webpage.
No soil will be imported as a result of the project. 1,802 Cubic Yards of material will be cut from the Project Site. All cut soil to be used onsite as fill material shall be tested using screening levels as outlined in DTSC's Preliminary Endangerment Assessment (PEA) Guidance Manual before use.
Approximately 1,633 Cubic yards of soil will be exported as a result of grading activities. This clarification will be reflected in the document.
2.2 - Cut material will be stockpiled on site to be used for necessary fill activities, eliminating the need to import soil. All stockpiled soil to be used for “fill” activities shall be tested to assess potential contaminants of concern that meet screening levels as outlined in DTSC's Preliminary Endangerment Assessment (PEA) Guidance Manual before use.

In order for the Districts to conform to the requirements of the Federal Clean Air Act (CAA), the capacities of the Districts’ wastewater treatment facilities are based on the regional growth forecast adopted by the Southern California Association of Governments (SCAG). Specific policies included in the development of the SCAG regional growth forecast are incorporated into clean air plans, which are prepared by the South Coast and Antelope Valley Air Quality Management Districts in order to improve air quality in the South Coast and Mojave Desert Air Basins as mandated by the CAA. All expansions of Districts’ facilities must be sized and service phased in a manner that will be consistent with the SCAG regional growth forecast for the counties of Los Angeles, Orange, San Bernardino, Riverside, Ventura, and Imperial. The available capacity of the Districts’ treatment facilities will, therefore, be limited to levels associated with the approved growth identified by SCAG.
As such, this letter does not constitute a guarantee of wastewater service, but is to advise the applicant that the Districts intend to provide this service up to the levels that are legally permitted and to inform the applicant of the currently existing capacity and any proposed expansion of the Districts’ facilities.
It is noted that service will be provided up to the levels that are legally permitted. No Changes Made.

Caltrans is aware of challenges that the region faces in identifying viable solutions to alleviating congestion on State and Local facilities. With limited room to expand vehicular capacity, this project should incorporate multimodal and complete streets transportation elements that will actively promote alternatives to car use and better manage existing parking assets. Prioritizing and allocating space to efficient modes of travel such as bicycling and public transit can allow streets to transport more people in a fixed amount of right-of-way.
Each residential unit will have a garage in which alternative modes of transportation can be stored.
Several Long Beach Transit routes serve the Project Site, including: Routes 71/72 along Orange Avenue, Routes 21/22 along Cherry Avenue, and Route 102/104 along Willow Street. Per Section
21.48 of the City of Signal Hill Municipal Code, new development projects are required to provide funds for the acquisition, improvement, and expansion of street, parkway, thoroughfare, intersection, and other traffic and circulation improvements. This ordinance is intended to authorize reasonable fees to be collected related to new development so that the burdens of installing public improvements, the need for which is created by certain new development projects and which will benefit certain land in addition to such development projects. In addition to this, measures for construction traffic control must be met to ensure safety during work hours, stating that all work areas, lane closures, and all warning lights, flashers and devices used shall be protected, installed and provided in accordance with the current Caltrans Manual of Traffic Controls and/or Work Area Traffic Control Handbook.

The project’s construction activities are expected to generate a maximum of 60 additional daily vehicle trips (30 round trips) and around 1,163.2 VMT per day, due to the movement of workers and heavy-duty trucks to and from the site. These trips are temporary and will cease once construction ends, without impacting operational traffic. As stated in the OPR Technical Advisory on Evaluating Transportation Impacts in CEQA (December 2018), projects generating fewer than 110 daily trips typically result in less-than-significant transportation impacts; therefore, the project’s impact would be minimal.
This data is consistent with the ISMND as written. It is noted that this is consistent with a less-thansignificant transportation impact.No Changes Made.

Once constructed, the project is expected to generate a maximum of 76.32 trips per day, resulting in approximately 585.71 VMT per day. Per OPR's Technical Advisory on Evaluating Transportation Impacts in CEQA (December 2018), projects generating fewer than 110 daily trips typically pose a less-than-significant transportation impact unless substantial evidence indicates otherwise. Since the project falls well below this threshold, it is anticipated to have minimal long-term impacts on transportation and circulation.
