Water Quality Certification Public Notices

Water Quality Certification Actions - Applicants for federal permits that involve dredge or fill activities in surface waters (including wetlands) are required to obtain certification from the state verifying that the activity will comply with state water quality standards. Most of these federal permits are referred to as 404 permits (in reference to Section 404 of the federal Clean Water Act). Applicants for some other types of federal license or permits (ex. FERC licenses) that authorize activities that may result in discharges to waters of the United States are also required to obtain state certification. This state certification is called 401 Certification (in reference to Section 401 of the Clean Water Act). In California, 401 certification actions are the responsibility of the State and Regional Water Quality Control Boards. It is the policy of this Regional Board to provide public notice of pending 401 Certification actions in order to gather comments from concerned agencies and the public. The following list contains notification of pending 401 Certification actions.

Redwood House Road Culvert Replacement Project 1B21057WNHU Humboldt 40.543647, -123.915417 Heavy rains caused high flows and debris within South Fork Yager Creek to damage a 15-ft wide x 8-ft high x 60-ft long steel arch culvert on Redwood House Road PM 7.14. High creek flows along with downed trees and other woody debris blocked the culvert inlet, causing the creek to scour the embankment and partially collapse the culvert inlet. Creek flows also flowed over the roadway causing significant damage. Permanent repair of the culvert is planned for summer 2021 and involves replacing the existing failed steel culvert with a new larger arch culvert (32-ft wide x 12-ft high x 60-ft long) on concrete footings, placing Engineered Streambed Material (rock/gravel weirs) and placing rock armoring at both the inlet and outlet of the new culvert. Once the new culvert is installed, both the inlet and outlet areas will be armored with ¼ -ton rock. Design plans show an estimated 260 tons of RSP and 30cy of Class 2 Aggregated Base being used. Once completed, all disturbed areas will be seeded and straw mulched along with the installation of fiber rolls (wattles) to help prevent erosion. Additionally, willow stakes and several alder trees will be planted along the immediate stream channel. 4/13/2021 - 5/4/2021 Brandon Stevens, brandon.stevens@waterboards.ca.gov, (707) 576-2377

This project will reduce the frequency and severity of collisions by improving horizontal and vertical curves and widening shoulders on a 0.3-mile section of State Route 36 located six miles east of Carlotta, where the collision rate is 3.7 times the statewide average. Two culverts will be replaced and a new Mechanically Stabilized Embankment retaining wall and Midwestern Guardrail System will be constructed. Project construction will cause approximately 0.054 acres of permanent impacts and 0.105 acres of temporary impacts to forested wetlands. Temporary impacts will be restored with erosion control and reseeding. Permanent wetland impacts are proposed to be addressed by offsite Mitigation. Construction will occur over 150 working days from January 2022 to December 31, 2022.

Caltrans will replace or repair eight deteriorating culverts on US Route 101 in Mendocino County within 4 miles north and 18 miles south of the State Route 1 intersection in Leggett. Six of the culverts are jurisdictional under Sections 401 and 404 of the Clean Water Act. Culvert replacement will use cut and cover methods working from the roadway with minimal soil disturbance or impacts to streambeds. Permanent impacts of 2 linear feet will be offset by several shortened culverts of increased diameter. Temporary impacts to streambed amount to 522 linear feet, with no impacts to riparian vegetation or wetlands. Disturbed areas will receive erosion control treatment. In-stream work will be from June 15 to October 15. The Project will begin in June 2021 and be completed in October 2021, with 43 working days of construction.

CDOT Dr. Fine Bridge (Smith River) Highway 101 Bridge Replacement

1A21029WNDN

Del Norte

41.874 °N,
124.138 °W

Caltrans will replace the Smith River Bridge (#01-0020) (Dr. Fine Bridge) to improve safety, connectivity, and reliability of the bridge. The new bridge will be supported by three piers with longer spans and will meet current material, geometric, scour, and seismic design standards. The Project will require temporary stream crossings, construction trestles, and cofferdams to dewater for pier demolition and construction. A temporary gravel pad within the channel will be installed and removed for each of three construction seasons. Work includes vegetation clearing, construction of a temporary bridge and access roads, bridge demolition and construction, and repaving. Water quality impacts include permanent physical loss of 0.012 acres due to pier construction. Permanent impacts to be restored include approximately 1,455 LF of rivers and streams, 0.057 acres of wetlands, and 2.468 acres to riparian. Approximately 1.13 acres of temporary impacts to the river will occur for the gravel work pad. Impacts will be avoided and minimized to the extent possible. All temporary and permanent impacts occurring for the duration of the project, including temporal loss, will be fully mitigated onsite by regrading, restoration, replanting, and wetland creation, and offsite by streambed re-establishment at Dominie Creek and wetland enhancement by invasive plant removal at the 45-acre Hambro Parcel. Construction is planned for 795 working days over four years, from September 1, 2021 to October 15, 2025. Instream work will be from June 15 to October 15. The 5-year restoration mitigation and monitoring period will continue to October 15, 2031.

Baumgardner Ranch Project 1B190131WNSO Sonoma 38.7950575,                         -123.0119234 The Project is a 28.5-acre residential development project creating a “workforce village” that provides
housing for all segments of the income spectrum for the City of Cloverdale. The Project includes the construction of approximately 304 housing units, including 79 single-family homes, 60 row-style homes, 166 multi-family units, and a Community Building encompassing approximately 18.7 acres of the Project Area. The Project would widen Sandholm Lane and Kelley Road along the Project boundary. Widening of Kelley Road includes the replacement of an existing 30-foot culvert with a new 58-foot-long pre-cast concrete crossing. The Project would dedicate approximately 9.8 acres of privately-owned Open Space that encompasses the existing oak woodlands along the western portion of the Project Area, the homestead, and the unnamed drainage to Icaria Creek to the west of the Project. No public access or recreational activities will be allowed within the Open Space. A 10-foot-wide walking trail and associated fencing would be established adjacent the open space area containing the unnamed drainage in the eastern portion of the Project Area. The proposed Project would impact 0.064 acre of seasonal wetlands, 0.030 acre of ditch, and 0.005 acre of an intermittent drainage. Mitigation for these impacts are onsite and include a combination of wetland creation, riparian habitat enhancement, and watercourse crossing upgrade.

Patrick’s Point Drive PM 1.9 Storm Damage Culvert Repair 1B21044WNHU Humboldt 41.08755, -124.14896 Heavy rains caused high flows of McNeil Creek to damage a concrete headwall and inlet area of a 4-ft diameter culvert underneath Patrick’s Point Drive. High creek flows overwhelmed the culvert inlet, causing the creek to flow over, around and behind the headwall. This resulted in excessive scour to the embankment and partial collapse of the headwall. The inlet of the culvert detached from the headwall and became partially buried in the creek substrate. Additionally, subsequent investigations have revealed that a portion of the culvert underneath the road has disconnected and has partially collapsed as well. The culvert is roughly 40 feet underneath the roadway thus making permanent repair necessary to prevent future catastrophic road failure. Immediate emergency work was done to remove the concrete headwall and a portion of the culvert inlet that was damaged. Rock was placed along the scoured embankment along with re-creating a "headwall" with the rock. Work was done to ensure that flows from the creek entered the culvert unimpeded and would not scour behind the culvert inlet again. Permanent repair of the culvert is planned for summer 2021 and involves using a “jack and bore” or “trenchless culvert installation" methodology to “push” a larger 5-ft diameter culvert longitudinally through the existing 4-ft diameter failed culvert. This methodology for replacing the failed culvert was decided as the most feasible option since excavating the existing culvert would require a huge opening in the roadway, temporary placement of excavated fills within the roadway and elsewhere, the removal of several large trees, indefinite road closure for several months, and would result in a much more expensive project overall. 3/30/2021 - 4/20/2021 Brandon Stevens, Brandon.Stevens@waterboards.ca.gov, (707) 576-2377

Redwoods Rising - Greater Prairie Creek Ecosystem Restoration Project 1B190069WNHU Humboldt 41.321006° N, 124.043895° W The purpose of the Greater Prairie Creek Ecosystem Restoration Project is to rehabilitate the Greater Prairie Creek watershed and restore ecosystem processes that have been degraded by historical land use. Rehabilitation would be accomplished through thinning second-growth forests to reduce stand density and alter species composition to promote growth of remaining trees, understory vegetation, and development of multi-story canopy; removing or repairing roads to reduce the potential for erosion and sedimentation into streams; restoring instream habitat complexity; and augmenting riparian corridors by planting native vegetation. These actions are needed to accelerate development of forest characteristics more typical of late-seral forests, prevent chronic and catastrophic sediment inputs to creeks, and enhance habitat for populations of aquatic and terrestrial species.
