Erosion Control Plan for the XYZ Ranch

Ownership in the Garcia River Watershed

Introduction

This Erosion Control Plan is submitted for the 000 acres in the Garcia River watershed. This plan along with a Site-Specific Management Plan is intended to comply with Option 2 of the Action Plan for the Garcia River Watershed Sediment Total Maximum Daily Load. The Erosion Control Plan (ECP) identifies areas of sediment delivery, identifies areas at risk of sediment delivery, and presents a schedule to control all sediment delivery associated with past and present land management activities.

The current land management activities are….. X acres are devoted to high quality timber production and Y acres are devoted to agriculture. The primary agriculture operation involves….

Erosion Control Plan

This plan is outlined into four basic components as detailed in the Action Plan for the Garcia River Watershed Sediment Total Maximum Daily Load: 1) Baseline Data Inventory, 2) Sediment Reduction Schedule, 3) Assessment of Unstable Areas, and 4) Monitoring Plan.

1. Baseline Data Inventory

Table 1  Sediment Delivery Sites

This Sediment Delivery Site Inventory contains a description of all active an potential sediment sources greater than 10 cubic yards resulting from roads, landings, skid trails, timber operations and agricultural operations, and other significant human-caused earth movement activities that have or might have the ability to enter waters of the states.

The Inventory method used for this inventory was…(ex. Sediment TMDL Inventory and Monitoring Worksheet developed by U.C. Davis).

2. Sediment Reduction Schedule

All sediment delivery site mitigation will be completed by January 3, 2015 for timber operations, and January 3, 2025 for agricultural operations. The Sediment Reduction Schedule will control, in order of priority, all Sediment Delivery Sites in such a manner as to reduce the sediment from sites representing 10 percent of the overall volume of inventoried sediment every year for timber operations. For agricultural operations the schedule will control 20 percent of the overall volume of inventoried sediment every four years. A combination of factors will dictate the priority of work. A high erosion hazard classification of a road segment and proximity to a watercourse will make a road a priority. Also, those sites with the greatest potential to discharge sediment to a watercourse that supports fish will make a site a priority.

3. Assessment of Unstable Areas

The assessment of unstable areas identifies through (ex. Field inventory and/or data analysis; or Modeling) areas of instability across the property. Unstable areas are areas with naturally high risk of erosion and areas or sites that will not reasonable respond to efforts to prevent, restore or mitigate sediment discharges. The unstable areas included are all active and potential shall and deep-seated landslides, debris flows, debris slides, debris torrents, earthflows, headwall swales, inner gorge features, and unstable areas. The assessment also includes all known active or potentially active gullies and streambank erosion sites that are not included in # 1 above.

This assessment was done utilizing …(ex. California Department of Conservation Maps, Soils Map, Field Inventory Worksheets, or digital terrain types models)

The soil classification of XYZ Ranch is…

4. Monitoring Plan (Example of only one of many possibilities)

Working with the University of California Cooperative Extension (UCCE) and the Natural Resource Conservation Services (NRCS), XYZ Ranch has located 10 photo point monitoring sites that represent stream and hillslope conditions. Each of these sites will be photographed four times each year according to protocols developed by UCCE and the NRCS. We will also be conducting the following adjunct monitoring to coordinate with the photopoint monitoring. Although the instream and hillslope monitoring are voluntary components of the TMDL Action Plan, other monitoring parameters will be inventoried as a means of improving the scientific understanding of the Garcia Watershed.
