Document Description
Toland Lane is a paved road and access to SMUD’s Solano Wind Project, and critical infrastructure such as PG&E’s gas pipeline and electrical transmission lines and towers. Local farmers also use the roadway. Road damage recently appeared over two (2), side-by-side 48-inch Corrugated Metal Pipe (CMP) culverts due to the combination of heavy traffic loading and heavy rains which eroded portions of the pipes and caused the road to collapse. This pair of culverts collects stormwater drainage from the roadway along with hillside drainage flowing from the west. The portion of the road that collapsed measures approximately 10 feet in diameter and is 2 to 3 feet deep. One of the existing 48” CMP’s had completely corroded along a portion of the southern side of the pipe nearest the inlet, causing erosion of the southern road embankment. The pipe appears to have settled with the soft soil, causing a reduction of flow capacity and inability to provide adequate drainage away from the site. Vegetation and debris were observed along the inlet and outlet of the CMP culvert, contributing to the reduced flow capacity and corrosion.
Due to the likelihood of further deterioration of the roadway caused by future rain events and urgent use of the roadway by PG&E to maintain critical infrastructure, SMUD determined that the culvert should be replaced as an emergency project as soon as possible. Temporary repairs were made between January 20 and 27, 2022. Vegetation near the inlet and outlet was removed. The collapsed asphalt was saw cut and removed. The soft and saturated soil above the collapsed 48” CMP was excavated, removed, until suitable soil was encountered. A cement slurry mix was used for backfill for temporary support of vehicle traffic. Steel plates were laid over the top of the cement slurry mix and will be left in place until a permanent repair can be made in the Summer of 2022.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Categorical Exemption (CEQA PRC §21080(b)(2), CEQA Guidelines §15301 (c) Existing highways and streets & (d) Restoration
Reasons for Exemption
Under CEQA Guidelines § 15062, a lead agency must identify the rationale for making the determination that a project is exempt under CEQA. SMUD has determined that the Toland Lane Emergency Road Repair Project is exempt under CEQA Guidelines § 15269(b) which states that emergency projects are exempt from the requirements of CEQA when “emergency repairs to publicly or privately-owned service facilities necessary to maintain service essential to the public health, safety, or welfare. Emergency repairs include those that require a reasonable amount of planning to address an anticipated emergency,” (c), which reads “Specific actions necessary to prevent or mitigate an emergency…” § 15301 (c) which reads, “Existing highways and streets…and similar facilities (this includes road grading for the purpose of public safety)…” and (d), which reads “Restoration or rehabilitation of deteriorated or damaged structures, facilities, or mechanical equipment to meet current standards of public health and safety…” The Toland Lane Emergency Road Repair Project involves removing debris from the inlet and outlet of the culverts to prevent erosion, placing cement slurry to provide temporary support of vehicle traffic, and placing steel plates over the repaired area until a permanent repair is completed, and therefore is considered exempt in accordance with CEQA Guidelines §15269 and §15301.
