About this file
This document is a Ground Penetrating Radar (GPR) and potholing utility investigation report prepared by Aragon Geotechnical, Inc. for the San Bernardino County Department of Public Works, Special Districts in support of the proposed Wildland Firefighting Helitanker Station project located at Glen Helen Regional Park Well 5 (Glen Helen Road and Forest Lane, San Bernardino, California 92407). The investigation was conducted on July 9 and 10, 2026, by 3 Thirteen Subsurface using GPR utility locating and potholing services. The scope of work identified the existing water service line's alignment, depth, size, direction of travel, and lateral connections. Six pothole locations (P1 through P6) were excavated to verify and document subsurface utilities, with depths ranging from 2.32 feet to 3.54 feet below existing ground surface. The water line was identified as a 10-inch diameter pipe constructed of both PVC and concrete thrust block materials, running in multiple directions (NE/SW, N/S, and NW/SE) across the project site. All potholed locations have been documented with photographs, cross-section diagrams, and precise GPS coordinates referenced to the ASCE 38-02 Standard Guideline for utility data classification.
The report classifies utility information using Utility Quality Level A (QL-A) for physically exposed utilities at pothole locations, providing the highest level of confidence for horizontal and vertical positioning. The investigation was performed under strict compliance with California Government Code Section 4216-4216.9 regarding safe location of underground utilities. The report includes a partial underground utility map with six sheets showing pothole locations, utility alignments, and related infrastructure features. The document explicitly disclaims that 3 Thirteen Subsurface provides utility mapping services only and does not offer engineering consultation, design, or construction services. Clients are advised to seek licensed engineering professionals for design and engineering-related inquiries and to conduct independent verification of utility locations, particularly for critical construction or excavation areas. The investigation deliverables support the design and construction planning phases of the helitanker station project by providing documented subsurface utility information to prevent damage during future excavation and construction activities.

UNDERGROUND UTILITY MAP
WITHIN THE CITY OF SAN BERNARDINO, COUNTY OF SAN BERNARDINO, CALIFORNIA
Reference: American Society of Civil Engineers (ASCE) Standard 38-02 The utility information depicted on this map is classified in accordance with the ASCE 38-02 Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data. The quality levels defined below describe the method used to obtain the utility information and the relative reliability of the depicted data.
UTILITY QUALITY LEVEL A (QL-A)
Utility Quality Level A represents the highest Level of confidence for utility information. Information is obtained through the physical exposure of a utility at a specific location using non-destructive excavation methods such as vacuum excavation. This process confirms the precise horizontal and vertical position of the utility at the point of exposure.
Measurements are typically taken from the exposed facility and referenced to visible surface features. QL-A data represents conditions observed only at the exposed point and may not represent conditions between exposure locations.
UTILITY QUALITY LEVEL B (QL-B)
Utility Quality Level B information is obtained through the use of surface geophysical locating methods, such as electromagnetic locating equipment and ground penetrating radar, to determine the approximate horizontal position of subsurface utilities. The resulting markings represent the interpreted path of utilities based on instrument response and field conditions. These utilities are then transferred to the map based on surface markings and field observations. QL-B data represents approximate horizontal alignment only and should not be interpreted as precise excavation coordinates.
UTILITY QUALITY LEVEL C (QL-C)
Utility Quality Level C information is derived from visible above-ground utility features, such as valves, pedestals, meters, risers, or other surface indicators. These features are correlated through professional judgment and field interpretation to infer possible subsurface utility QL-C information is approximate and interpretive in nature.
UTILITY QUALITY LEVEL D (QL-D)
Utility Quality Level D information is obtained from existing records, drawings, maps, or verbal recollections. These sources may include utility owner records, as-built drawings, or other historical documentation. Accuracy and completeness may vary. QL-D information should be considered for reference purposes only.
IMPORTANT NOTICE
Conditions may vary, and additional utilities or variations in location may exist. This map does not guarantee the presence or absence of utilities and should not replace proper notification of utility owners or compliance with local excavation notification requirements.
