These initiatives help landowners improve their land management techniques, adopt environmentally friendly practices, and minimize the impact of their activities on local water quality and ecosystems.

Regulations and Permitting for Erosion Control

There are specific regulations and permitting processes in place to ensure that erosion control requirements are met for construction and land development projects. These regulations are designed to maintain consistency and compliance with the National Pollutant Discharge Elimination System (NPDES), the county code, and other relevant local and state environmental laws. The regulatory body in Washington State is the Department of Ecology (DOE); in Oregon State the Department of Environmental Quality (DEQ).

Developers and contractors must obtain the appropriate permits and certifications before beginning a project that involves soil disturbance or has the potential to impact local water quality. For example, large parcel construction projects require certified erosion and sediment control personnel who have completed approved courses through the Washington State Department of Ecology.

Complying with erosion control and soil testing regulations not only helps preserve the county's environmental integrity but also helps developers avoid costly fines, delays, or legal repercussions. Failure to adhere to these requirements can result in penalties, including stop work orders, fines, and even criminal charges in severe cases. Thus, it is vital for any individual or business undertaking construction or land development familiarize themselves with the applicable regulations and permitting processes.

Understanding Clark County's Erosion Control Requirements

Erosion Control Plan Requirements for Projects Over 1 Acre

In Clark County, WA, projects that disturb more than one acre of land are required to have an Erosion Control Plan in place. This is in accordance with the National Pollutant Discharge Elimination System (NPDES) requirements, as well as county code. An Erosion Control Plan lays out the necessary measures to prevent soil erosion, sedimentation, and stormwater runoff. Developers must submit their plans electronically via the ePlan Review platform, as paper submittals are no longer accepted as of September 19, 2022.

The Erosion Control Plan should include detailed information about the construction site, including the location of sensitive areas such as wetlands, water bodies, and critical habitats. It should also outline the proposed erosion and sediment control measures that will be implemented during construction to minimize the risk of water pollution and environmental damage. Examples of such measures include silt fences, sediment basins, vegetative buffers, and mulching.

To ensure compliance with these requirements, developers must have their Erosion Control Plan approved by the Washington State Department of Ecology or a certified erosion and sediment control person. In some cases, Clark County may also require specific certifications such as the Washington State Department of Ecology-approved courses for large parcel construction. Developers can find a certified member by contacting the Building Industry Association of Clark County, which maintains a list of certified erosion and sediment control professionals.

Temporary Erosion Control Measures for Smaller Projects

For smaller projects in Clark County, where less than one acre of land is disturbed, temporary erosion control measures may be sufficient to protect the environment and comply with regulations. These measures are designed to be used during the construction phase to prevent soil erosion, manage sedimentation, and control runoff. Examples of temporary erosion control measures include sediment barriers, construction exits, and temporary stabilization of disturbed areas with straw mulch, gravel, or temporary seeding.

Although these smaller projects may not require a full-fledged Erosion Control Plan, it is still essential for developers to be mindful of the potential impact their activities may have on the environment. Proactively implementing temporary erosion control measures can help prevent costly and time-consuming remediation efforts in the future.

Developers working on smaller projects should consult with the appropriate county officials to ensure they are following all necessary guidelines and regulations for erosion control. In some cases, Clark County may still require a certain level of certification, such as a county certification for single-family permits, or adherence to specific requirements in terms of temporary erosion control measures.

Stormwater Management Best Practices

When it comes to erosion control, stormwater management is a critical component. Developers should implement best practices to effectively manage stormwater runoff and prevent water pollution. Some of these best practices include using permeable pavement or pavers, installing green roofs or rain gardens, and employing bioretention cells to capture and filter stormwater on-site.

Additionally, developers can implement a variety of structural and non-structural measures to control stormwater flow during and after construction. These practices can help to slow down and infiltrate runoff, reducing the impact on the surrounding environment. Examples include creating swales and detention basins for stormwater storage, designing naturalized channels to replace concrete ditches, and establishing vegetative buffers along streams to filter runoff and prevent erosion.

Maintenance is key when it comes to stormwater management best practices. Regular inspections and maintenance of stormwater management systems ensure that they are functioning correctly and meeting regulatory requirements. This includes cleaning out sediment from basins, repairing damaged erosion control measures, and ensuring proper vegetation establishment in buffer zones and stormwater treatment areas.

Erosion Control Inspection and Maintenance

To maintain compliance with erosion control requirements, developers must regularly inspect and maintain erosion control measures throughout the construction and post-construction phases. Inspections should be performed by a certified erosion and sediment control person or other qualified individual, and should focus on verifying the effectiveness of temporary measures and identifying potential issues that need addressing.

During construction, developers should implement a schedule of regular inspections, generally on a weekly basis and following any significant rainfall events. Inspections should assess the condition of erosion control measures and document any maintenance or repairs needed. Prompt action should be taken to address any identified issues, ensuring the continued effectiveness of the erosion control measures and compliance with regulatory requirements.

Once the construction phase is complete, developers should transition to post-construction maintenance of erosion control measures. This phase involves managing any remaining silt fences, mulching disturbed areas, repairing damaged erosion control structures, and ensuring proper establishment of vegetation. Developers should retain records of all inspections, maintenance activities, and repairs, as these may be required as part of ongoing regulatory compliance monitoring by the county or state.
