Environmental Risk Information Services (ERIS) can search the following databases. The extent of historical information varies with each database and current information is determined by what is publicly available to ERIS at the time of update. ERIS updates databases as set out in ASTM Standard E1527-13 and E1527-21, Section 8.1.8 Sources of Standard Source Information:
"Government information from nongovernmental sources may be considered current if the source updates the information at least every 90 days, or, for information that is updated less frequently than quarterly by the government agency, within 90 days of the date the government agency makes the information available to the public."

Federal
National Priority List: rr-NPL-bb
The U.S. Environmental Protection Agency (EPA)'s National Priorities List (NPL) includes the most serious uncontrolled or abandoned hazardous waste sites identified for possible long-term remedial action under the Superfund program, based primarily on the score a site receives from EPA's Hazard Ranking System. A site must be on the NPL to receive money from the Superfund Trust Fund for remedial action. This data includes NPL sites represented as polygons, where available, that can be sourced from the EPA NPL Superfund Site Boundaries dataset, refreshed by the Shared Enterprise Geodata and Services (SEGS). These site boundaries represent the footprint of a whole site, the sum of all the Operable Units (OUs) and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary. As site investigation and remediation progress, OUs may be added, modified or refined. Data provided by external parties is not independently verified by EPA.

This boundary data is made available to the public strictly for informational purposes. Where there is no polygon boundary data available for a given site, the site is represented as a point.

Government Publication Date: Sep 25, 2024
National Priority List - Proposed: rr-PROPOSED NPL-bb
Sites proposed by the U.S. Environmental Protection Agency (EPA), the state agency, or concerned citizens for addition to the National Priorities List (NPL) due to contamination by hazardous waste and identified by the EPA as a candidate for cleanup because it poses a risk to human health and/or the environment. Sites represented as polygons, where available, can be sourced from the EPA NPL Superfund Site Boundaries dataset, refreshed by the Shared Enterprise Geodata and Services (SEGS). These site boundaries represent the footprint of a whole site, the sum of all the Operable Units (OUs) and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary.

Data provided by external parties is not independently verified by EPA. This boundary data is made available to the public strictly for informational purposes. Where there is no polygon boundary data available for a given site, the site is represented as a point.

Government Publication Date: Sep 25, 2024
Deleted NPL: rr-DELETED NPL-bb
Sites deleted from the U.S. Environmental Protection Agency (EPA)'s National Priorities List (NPL). The National Oil and Hazardous Substances Pollution Contingency Plan (NCP) establishes the criteria that the EPA uses to delete sites from the NPL. In accordance with 40 CFR 300.425.(e), sites may be deleted from the NPL where no further response is appropriate. Sites represented as polygons, where available, can be sourced from the EPA NPL Superfund Site Boundaries dataset, refreshed by the Shared Enterprise Geodata and Services (SEGS). These site boundaries represent the footprint of a whole site, the sum of all the Operable Units (OUs) and the current understanding of the full extent of contamination; for Federal Facility sites, the total site polygon may be the Facility boundary.

The U.S. Environmental Protection Agency's (EPA) Superfund Program has deployed the Superfund Enterprise Management System (SEMS), which integrates multiple legacy systems into a comprehensive tracking and reporting tool. This inventory contains active sites evaluated by the Superfund program that are either proposed to be or are on the National Priorities List (NPL) as well as sites that are in the screening and assessment phase for possible inclusion on the NPL. The Active Site Inventory Report displays site and location information at active SEMS sites. An active site is one at which site assessment, removal, remedial, enforcement, cost recovery, or oversight activities are being planned or conducted. This data includes SEMS sites from the List 8R Active file as well as applicable sites from the EPA's Facility Registry Service map tool.

Government Publication Date: Jul 24, 2024
Inventory of Open Dumps, June 1985: rr-ODI-bb
The Resource Conservation and Recovery Act (RCRA) provides for publication of an inventory of open dumps. The Act defines "open dumps" as facilities which do not comply with EPA's "Criteria for Classification of Solid Waste Disposal Facilities and Practices" (40 CFR 257).

Government Publication Date: Jun 1985
SEMS List 8R Archive Sites: rr-SEMS ARCHIVE-bb
The U.S. Environmental Protection Agency's (EPA) Superfund Enterprise Management System (SEMS) Archived Site Inventory displays site and location information at sites archived from SEMS. An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program at this time. This data includes sites from the List 8R Archived site file.

Comprehensive Environmental Response, Compensation and Liability Information System - CERCLIS:
rr-CERCLIS-bb
Superfund is a program administered by the United States Environmental Protection Agency (EPA) to locate, investigate, and clean up the worst hazardous waste sites throughout the United States. CERCLIS is a database of potential and confirmed hazardous waste sites at which the EPA Superfund program has some involvement. It contains sites that are either proposed to be or are on the National Priorities List (NPL) as well as sites that are in the screening and assessment phase for possible inclusion on the NPL. The EPA administers the Superfund program in cooperation with individual states and tribal governments; this database is made available by the EPA.

Government Publication Date: Oct 25, 2013
EPA Report on the Status of Open Dumps on Indian Lands: rr-IODI-bb Public Law 103-399, The Indian Lands Open Dump Cleanup Act of 1994, enacted October 22, 1994, identified congressional concerns that solid waste open dump sites located on American Indian or Alaska Native (AI/AN) lands threaten the health and safety of residents of those lands and contiguous areas. The purpose of the Act is to identify the location of open dumps on Indian lands, assess the relative health and environment hazards posed by those sites, and provide financial and technical assistance to Indian tribal governments to close such dumps in compliance with Federal standards and regulations or standards promulgated by Indian Tribal governments or Alaska Native entities.

Government Publication Date: Dec 31, 1998
CERCLIS - No Further Remedial Action Planned: rr-CERCLIS NFRAP-bb An archived site is one at which EPA has determined that assessment has been completed and no further remedial action is planned under the Superfund program at this time. The Archive designation means that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list this site on the National Priorities List (NPL). This decision does not necessarily mean that there is no hazard associated with a given site; it only means that, based upon available information, the location is not judged to be a potential NPL site.

Government Publication Date: Oct 25, 2013
CERCLIS Liens: rr-CERCLIS LIENS-bb
A Federal Superfund lien exists at any property where EPA has incurred Superfund costs to address contamination ("Superfund site") and has provided notice of liability to the property owner. A Federal CERCLA ("Superfund") lien can exist by operation of law at any site or property at which EPA has spent Superfund monies. This database is made available by the United States Environmental Protection Agency (EPA). This database was provided by the United States Environmental Protection Agency (EPA). Refer to SEMS LIEN as the current data source for Superfund Liens.

PFAS Waste Transfers from RCRA e-Manifest : rr-PFAS E-MANIFEST-bb This Per- and Poly-Fluoroalkyl Substances (PFAS) Waste Transfers dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. Every shipment of hazardous waste in the U.S. must be accompanied by a shipment manifest, which is a critical component of the cradle-to-grave tracking of wastes mandated by the Resource Conservation and Recovery Act (RCRA). According to the EPA, currently no Federal Waste Code exists for any PFAS compounds. To work around the lack of PFAS waste codes in the RCRA database, EPA developed the PFAS Transfers dataset by mining e-Manifest records containing at least one of these common PFAS keywords: • PFAS • PFOA • PFOS • PERFL • AFFF • GENX • GEN-X (plus the Vermont state-specific waste codes). Limitations: Amount or concentration of PFAS being transferred cannot be determined from the manifest information. Keyword searches may misidentify some manifest records that do not contain PFAS. This dataset should also not be considered to be exhaustive of all PFAS waste transfers.

PFAS Industry Sectors: rr-PFAS IND-bb
This Per- and Poly-Fluoroalkyl Substances (PFAS) Industry Sectors dataset is made available via the U.S. Environmental Protection Agency's (EPA) PFAS Analytic Tools. The EPA developed the dataset from various sources that show which industries may be handling PFAS including: EPA's Enforcement and Compliance History Online (ECHO) records restricted to potential PFAS-handling industry sectors; ECHO records for Fire Training Sites identified where fire-fighting foam may have been used in training exercises; and 14 CFR Part 139 Airports compiled from historic and current records from the FAA Airport Data and Information Portal. Since July 2006, all certificated Part 139 Airports are required to have fire-fighting foam onsite that meet certain military specifications, which to date have been fluorinated (Aqueous Film Forming Foam). Limitations: Inclusion in this dataset does not indicate that PFAS are being manufactured, processed, used, or released by the facility. Listed facilities potentially handle PFAS based on their industrial profile, but are unconfirmed by the EPA. Keyword searches in ECHO for Fire Training sites may misidentify some facilities and should not be considered to be an exhaustive list of fire training facilities in the U.S.

This information was taken from report DRXTH-AS-IA-83A016 (Historical Overview of the Nike Missile System, 12/1984) which was performed by Environmental Science and Engineering, Inc. for the U.S. Army Toxic and Hazardous Materials Agency Assessment Division. The Nike system was deployed between 1954 and the mid-1970's. Among the substances used or stored on Nike sites were liquid missile fuel (JP-4); starter fluids (UDKH, aniline, and furfuryl alcohol); oxidizer (IRFNA); hydrocarbons (motor oil, hydraulic fluid, diesel fuel, gasoline, heating oil); solvents (carbon tetrachloride, trichloroethylene, trichloroethane, stoddard solvent); and battery electrolyte. The quantities of material a disposed of and procedures for disposal are not documented in published reports. Virtually all information concerning the potential for contamination at Nike sites is confined to personnel who were assigned to Nike sites. During deactivation most hardware was shipped to depot-level supply points. There were reportedly instances where excess materials were disposed of on or near the site itself at closure. There was reportedly no routine site decontamination.

Database Descriptions: This section provides a detailed explanation for each database including: source, information available, time coverage, and acronyms used. They are listed in alphabetic order.

Detail Report: This is the section of the report which provides the most detail for each individual record. Records are summarized by location, starting with the project property followed by records in closest proximity.

Distance: The distance value is the distance between plotted points, not necessarily the distance between the sites' boundaries. All values are an approximation.

Direction: The direction value is the compass direction of the site in respect to the project property and/or center point of the report.

Elevation: The elevation value is taken from the location at which the records for the site address have been plotted. All values are an approximation.

Source: Google Elevation API.

Executive Summary: This portion of the report is divided into 3 sections:
'Report Summary'- Displays a chart indicating how many records fall on the project property and, within the report search radii. 'Site Report Summary'-Project Property'- This section lists all the records which fall on the project property. For more details, see the 'Detail Report' section.
'Site Report Summary-Surrounding Properties'- This section summarizes all records on adjacent properties, listing them in order of proximity from the project property. For more details, see the 'Detail Report' section.

Map Key: The map key number is assigned according to closest proximity from the project property. Map Key numbers always start at #1. The project property will always have a map key of '1' if records are available. If there is a number in brackets beside the main number, this will indicate the number of records on that specific property. If there is no number in brackets, there is only one record for that property.

The symbol and colour used indicates 'elevation': the red inverted triangle will dictate 'ERIS Sites with Lower Elevation', the yellow triangle will dictate 'ERIS Sites with Higher Elevation' and the orange square will dictate 'ERIS Sites with Same Elevation.' Unplottables: These are records that could not be mapped due to various reasons, including limited geographic information. These records may or may not be in your study area, and are included as reference.

INTRODUCTION
This report includes the preliminary hydrologic analysis completed for Tentative Tract Map for Shea Homes development in the City of Aliso Viejo. The project is located south of Pacific Park Dr and west of Aliso Creek Rd. The project site is approximately 8.5 acres. The general location of the project site is shown on Figure 1, Vicinity Map.

The site is currently zoned professional office and the project proposes residential high density.

Given the existing site is developed with three two story office buildings and associated surface parking, it is not anticipated that the proposed project should greatly increase the runoff from the site.

Figure 1: Vicinity Map
The purpose of this preliminary hydrology and hydraulics report is to evaluate the hydrologic conditions for the proposed site development and identify preliminary storm drain facilities based on the results of the hydrologic analysis.

The primary objectives of this report are as follows:

1. Delineate the tributary drainage areas for the existing site.

2. Delineate the tributary drainage areas for the project conditions.

3. Based on the drainage patterns, ground slope, land use and soil type and using the Orange County Rational Method, perform hydrologic calculations of the on site drainage areas for the existing and proposed condition.

4. Based on the hydrology results, and physical site requirements, identify preliminary storm drain facilities to collect and convey the computed design discharges.

EXISTING SITE CONDITIONS
The existing property contains three two-story office buildings and surface parking. These areas are fairly flat, with a slope between 1-3%. The western edge of the property is an existing landscaped 2:1 slope. The runoff from the slopes is picked up by a series of v-ditches and downdrains which in turn tie into the private on-site storm drain system. There are a series of onsite inlets that take the site surface drainage and run it to the point of connection at the eastern edge.

The 30” RCP runs through the adjacent parcel (existing gas station at the corner of Aliso Creek and Pacific Park). From there the storm drain connects to a catch basin in Aliso Creek Rd and in turn enters an existing 42” RCP in Aliso Creek. That pipe joins an existing 72” RCP in Pacific Park which

SITE

continues down Woodfield. Along Woodfield the pipe upsizes to a 96” RCP and eventually outlets into Aliso Creek Channel.

PROJECT CONDITIONS
The project proposes the redevelopment of three existing commercial office buildings and associated parking lots into 137 town home and garden court condos with associated private streets, wet and dry utilities, landscaping, rec center and amenities. The overall drainage pattern will be very similar, still draining to the east and connecting to the existing offsite 30” RCP. The western landscaped slopes will primarily stay untouched. The grades along the boundaries will not significantly change. The streets will drain at approximately 0.7-2.0% across the site.

Figure 2: Project Location

HYDROLOGY ANALYSIS AND METHODOLOGY
Hydrologic calculations were performed in accordance with the methods described in the Orange County Hydrology Manual. The Rational Method Module of Advanced Engineering Software (AES) Computer Software Version 22.0 was used in performing the runoff calculations. The design discharges were computed by generating a hydrologic “link-node” model that divides the area into drainage sub-areas, each tributary to a concentration point or hydrologic “node” point determined by the proposed layout.

RAINFALL DATA
All precipitation data was based on the AES preset values for rainfall intensity for Orange County.

The intensity values are derived from the intensity-duration curves found on Figure B-3 of the Orange County Hydrology Manual. An antecedent moisture content AMC II condition was used for the 10 and 25 - year analysis.

RUNOFF INDEX AND LAND USE
A land use of open brush was used for the existing 2:1 landscape slopes along the western edge of the project. A land use of commercial was used for the existing parking and office buildings. A land use of apartments was used for the proposed condition given the calculated impervious rate of the site plan.

RESULTS & CONCLUSION
The table below summarizes the 10 & 25 flows at the point of connection.

Table 1 : 10 & 25 yr Existing vs. Proposed Runoff Peak Q (AES) Tributary Area
(ac) 10 Year Peak Flow (cfs) 25 Year Peak Flow (cfs)
Existing Condition 7.4 15.6 18.8
Proposed Condition 7.9 17.2 20.8
See Appendix A for complete 10 and 25 year existing conditions AES results. See Appendix B for complete 10 and 25 year proposed condition results.

From the results you can see the proposed condition has increased the peak flow leaving the site by approximately 11%. The main reason for this increase is the slight change in total tributary area.

The existing condition tributary area is only 7.4 acres compared to the proposed condition 7.9 acres. The main difference in the drainage areas is along the southern boundary. In the existing condition there are parking spaces along the southern boundary that drain away from the project site. In the proposed condition this runoff is captured in the on site storm drain system. There is also a slight increase in drainage area along the eastern edge where retaining walls will be used to increase the flat developable space. Overall the slight increase in flow can be attributed to the slight increase in drainage area and therefore there are no anticipated impacts to the site drainage.

In order to mitigate the peak increase down to the existing peak flow discharge the increase in runoff volume was calculated by running the unit hydrograph in both the existing and proposed conditions (plots can be found on the next page, Figures 3 & 4 and full results can be found in Appendix C). The precipitation losses were calculated following the Orange County Hydrology Manual. The areas with the same land use and soil type were totaled up to simplify the calculations.

The increase in volume was calculated by plotting the unit hydrograph for the proposed condition and drawing a horizontal line across at the existing condition peak flow. The area between the proposed hydrograph and existing peak was calculated and units converted into cubic feet (see Figure 5). This peak volume increase was calculated to be approximately 950 cubic feet. This increased volume will be mitigated by upsizing a sufficient stretch of on-site storm drain pipe and outletting the flow through an orifice to match the existing peak flow. See preliminary orifice calculations in Appendix D. Final sizing and orifice design will be part of final engineering. 1137
