Pothole Procedures and

Site Specific Details

DESCRIPTION OF POTHOLE PROCEDURES

AIRX Utility Surveyors performs a full range of specialized engineering services including Underground Utility Location and Vacuum Excavation (to verify depth and alignment of underground utilities).

Underground Utility Location employs sophisticated electronic locating devices to trace the route of an underground utility; then the route is marked on the surface with marking paint in paved areas, or with 60 penny nails and feathers in unpaved areas.

Vacuum excavation employs a vacuum truck in conjunction with high-pressure air or water to excavate material and expose an underground utility. A 10 to 12-inch diameter hole is first cored or chiseled through the pavement so that the vacuum hose and high-pressure air or water hose can be inserted.

Utilities found during potholing are located on the surface by placing two reference points (typically 36” apart) on either side of the pothole along the centerline (or edge) of the utility, using paving nails or 60 penny nails as appropriate. Depth measurements (to the nearest ½ inch) are taken midway between the two reference points.

Utility alignment, depth, and other data is marked with pink paint (on pavement), or on wood lath (unpaved areas).

SITE SPECIFIC DETAILS

AIRX was contracted by the County of San Diego to perform utility locating and potholing services in Ramona, California. A total of 8 potholes were excavated to establish conflicts and connection points on a variety of utilities.

The results of the data are contained in the attached spreadsheet and data sheets.

In preparation of these excavations, AIRX marked out the dig locations and called in for USA (Underground Service Alert). All traffic control plans and permits were drawn and applied for by AIRX and all traffic control was set up by

AIRX.

All the excavations and discovery went without any incident except for pothole 111, where an additional pothole was added in order to locate the desired water utility. Any changes and adjustments are mentioned in the Pothole Tabulation Report and the Pothole Data Sheets. All the results were annotated on the ground and in this report.

All Pothole and utility geographical locations were collected using the Trimble Catalyst DA1. The Trimble Catalyst DA1 uses RTK GNSS precision when collecting points. GPS locations are collected for GIS Map packages and are not to be used for Final Design. It is AIRX’s recommendation that all pothole locations and the active mark out should be surveyed to aid in the adjustment of utilities on the final plan and profile.

At each pothole location, the utility alignment was marked with pink paint, as well as paving nails or feathers. AIRX used potable water acquired offsite for excavation and all water and material vacuumed was disposed of off-site. No water was allowed to flow into storm drains or natural drainages. The potholes were covered with clean backfill material and compacted to 95% density in 3” lifts. The pavement was patched with Aquaphalt. All field work was performed between August 18, 2022, and August 24, 2022.

Temporary Traffic Control Devices shall comply with section 12-3 of Caltrans Standard Specifications unless otherwise noted.

All advance-warning signs for night closures shall be illuminated.

Placement of all signs shall not interfere with sight distance at driveways and intersections.

Position of post-mounted signs may be adjusted as necessary to optimize visibility or sign and/or obtain suitable placement area.

W20-1 signs and all other yellow or orange signs shall have a reflective background constructed of at least high-intensity (Type III) retroreflective sheeting.

All signs shall be equipped with orange flags and signs mounted on barricades shall have flashers on roads posted 50 MPH or higher.

PORTABLE CHANGEABLE MESSAGE SIGNS (PCMS)

PCMS shall comply with Section 6F.60 of the CA MUTCD.

Minimum of Two PCMS shall be considered when Road Closures (Partial or full) are necessary with detours.

STRIPING

No striping changes will be allowed to start on a Friday, unless otherwise noted and approved by the County Traffic Engineer.

Contractors shall layout and stripe all interim and final striping.

Contractor shall install all interim and final pavement markers, temporary tabs, and channelizers.

All striping changes shall be the responsibility of the Contractor. Striping modifications (due to construction), which exceed one (1) week in duration, require sandblasting. All sandblasting required by said striping changes shall be completed within 24 hours of that change.

All obliterated striping, raised pavement markers, pavement paint legends and markings, shall be reflectorized and replaced by the Contractor. Markings in thermoplastic shall be replaced in kind.

TRAFFIC SIGNAL LOOP DETECTORS

Signal equipment, such as loop detectors, damaged by the Contractor shall be replaced by the Contractor within 48 hours from time of damage.

DEVICES

Actual work area shall be protected with either orange reflectorized channelizing devices or by barricades equipped with type “A” flashers sufficient in number to prevent entry of both vehicles and pedestrians except as may be noted elsewhere. At no time shall a continuous row of flashers be used adjacent to a lane of traffic. Only steady-burn type “C” lamps shall be used under these circumstances.

All cones and/or post delineators shall be fitted with reflective sleeves of the appropriate color.

If used, all type “B” flashers shall operate 24 hours a day.

FLAGGING

Flagging operation shall use alternate one-way movement to pass traffic through the construction area.

Traffic shall be controlled at all times by flaggers. Flaggers shall be in constant communication with each other during the flagging operation. Advance flaggers shall be positioned upstream to warn traffic when queues develop. Additional flaggers may be required at intersections.

Where the one-lane section is short enough so that each end is visible from the other end, traffic will be controlled by means of a flagger at each end of the section. They should be able to communicate with each other verbally or by means of signals. These signals should not be such as to be mistaken for flagging signals. Where the end of one-way section is not visible from the other end, the flaggers shall maintain contact by means of radio or field telephones so that a flagger may know when to allow traffic to proceed into the section.

Flaggers shall be positioned near crest of hill allowing flaggers sufficient visibility of approaching traffic.

Flaggers shall be positioned so that they are easily visible to approaching traffic.

Flagger stations for work at night shall be illuminated as referenced in Part 6 of the “California Manual on Uniform Traffic Control Devices for Streets and Highways” (CA MUTCD), latest edition.

Where a one-lane temporary traffic control zone is short enough to allow visibility from one end to the other, traffic may be controlled by a single flagger. When a single flagger is used, the flagger shall be stationed on the shoulder opposite the obstruction or work space, or in a position where good visibility and traffic control can be maintained at all times.

If unable to utilize an alternate one-way flagging operation, Contractor shall contact Department of Public Works, Roads Division at (858) 694-3850 three (3) weeks prior to the proposed closure to determine its appropriateness. If a road closure is deemed appropriate, proper advanced notification (information signs, mailed and verbal notifications) is necessary to the emergency services, police services, businesses, residents and school districts.

ACCESS

Emergency vehicle access shall be maintained at all times.

Mail service, trash service, and school bus access shall be maintained at all times.

Motorist delay time shall not exceed 15 minutes unless otherwise approved by the County Traffic Engineer.

Contractor shall maintain access to all private driveways within the construction area at all times. If continuous access cannot be maintained, access must be provided as needed.

Adequate provisions shall be made for pedestrian traffic.

Adequate sight distance shall be maintained at all intersections in the vicinity of the work zone. If sight distance is affected by the traffic control, the contractor shall provide adequate distance per the County of San Diego Public Road Standards. Flaggers may be needed. The use of mirrors is not permitted as an alternative to providing adequate sight distance.

GENERAL

The Contractor shall be responsible for supplying, installing and maintaining all traffic control devices as shown on the plan along with additional traffic control devices that may be required to ensure safe movement of traffic and pedestrians through work area.

The Contractor shall be responsible for coordinating with any Special Events that will be affected in the area of the impending work and the Contractor shall be responsible for coordinating with other traffic control work zones, unless approved by County Inspector. The Contractor shall maintain 500 feet between beginning and end of work zone signage. Updated Special Event and Temporary Traffic Control information within the County may be found at the following link:

https://www.sandiegocounty.gov/content/sdc/dpw/roads/roadclose.html http://www.sandiegocounty.gov/content/sdc/dpw/roads/roadclose.html

The provisions of this section may be modified or altered if, in the opinion of the engineer, public traffic will be better served, and the work expedited. Said modifications or alterations shall not be adopted until approved in writing by the engineer.

The Contractor shall minimize the active construction zone to 250 feet to 500 feet unless approved by County Inspector.

The Contractor shall maintain maximum closure length based on work that can be completed at the end of the workday.

During non-working hours, the Contractor shall provide the full road width, which existed prior to the start of construction.

Bore shall offset 24” minimum from any streetlight and signal foundation and shall not occur beneath any streetlight and signal foundation.

All dirt and debris shall be removed from the roadway each day before completion of work. Street must be maintained in drivable condition at all times. Contractor shall not use the County right of way for storage of materials and equipment.

All Traffic Control devices, including advance warning signs, delineators, and barricades shall be removed from the roadway at the end of work each day (except W20-1 signs, if plate-bridging overnight.)

The Contractor is to restore roadway and all signing to prior conditions at the completion of work.

The Contractor shall coordinate their work with impacted agencies, San Diego Metropolitan Transit System (MTS), private road owners and/or Home-Owner Associations (HOA). Some agencies may require up to two weeks lead time.

Unless the work is specifically requested by the Engineer, or is Emergency in nature, no work will be performed on the following, County observed holidays:

New Year’s Day Independence Day Martin Luther King Jr. Day Labor Day President’s Day Veteran’s Day Cesar Chavez Day Thanksgiving Day Memorial Day Day after Thanksgiving Day Juneteenth Day Christmas Day
