About this file

Written by GovTribe AI · Sep 5, 2025

This document is a Natural Resources Conservation Service (NRCS) Emergency Watershed Protection Program project for clearing and snagging stream channels in Telfair County, Georgia, in response to Hurricane Helene. The project involves four specific sites along different highways (117, 149, 160): Fishing Creek, Little Horse Creek, Coffee Branch, and Turnpike Creek. Each site requires clearing and removing storm debris within a 250-foot upstream and 250-foot downstream area, with a 25-foot buffer on each side of the stream channel. The work includes removing fallen trees, leaning trees, storm-related vegetative materials, and potential obstructions that could impede stream flow or damage infrastructure during future flooding events.

The project emphasizes environmental preservation, requiring minimal disturbance to wetlands, riparian areas, and wildlife habitats. Contractors must follow strict cultural resources protection guidelines, including pausing work if any cultural materials are discovered and consulting with the NRCS GA State Archaeologist. Best management practices for erosion control, equipment maintenance, and debris disposal are detailed in the document. The project will be funded through the Emergency Watershed Protection Program, with the county responsible for obtaining temporary easements from affected property owners. Specific requirements include using hand equipment where possible, avoiding unnecessary vegetation removal, and stabilizing disturbed areas with appropriate vegetation and erosion control measures.

CONSERVATION PRACTICE STANDARD

CLEARING AND SNAGGING

CODE 326 (ft)

DEFINITION

Removal of specified vegetation along the bank (clearing) and selective removal of snags, drifts, or other obstructions (snagging) from natural or improved streams (includes channels).

PURPOSE

This practice is used to accomplish one or more of the following purposes:

• Restore flow capacity and direction to prevent and/or reduce ponding and flooding

• Prevent and or reduce excessive bank erosion

• Prevent and/or reduce sediment transported to surface water

• Prevent or reduce debris impacts to infrastructure CONDITIONS WHERE PRACTICE APPLIES: Any natural or improved stream where the removal of vegetation, trees, brush, and other obstructions is needed to accomplish one or more of the listed purposes.

CRITERIA

Site preparation Conduct a site investigation to identify any physical, chemical, or biological conditions that could affect the successful establishment of vegetation.

Clear areas to be planted of unwanted materials and smooth or shape, if needed, to meet planting purpose(s). Prepare a suitable seedbed for all seeded species. Rip compacted layers and re-firm the soil prior to seedbed preparation, as needed.

Location Include the work limits and flow area of the stream in the area to be cleared and snagged. Trees on the bank that are leaning over or other objects that may fall into the stream may be included. Clearing and snagging may also be used for other areas, such as temporary disposal areas or travelways, required for implementation of this practice.

Capacity Determine the capacity of the stream, both before and after modification as needed, using NRCS National Engineering Handbook (NEH) (Title 210), Part 654, Chapter 6, “Stream Hydraulics.” Select a value of Manning’s “n” roughness coefficient to determine stream capacity after modification that reflects the degree of natural changes and maintenance expected to occur in future years. Other capacity analysis may be performed at the discretion of the design engineer, area engineer, or state engineer.

Stability Clearing and snagging activities may affect stream stability. The effect on downstream and upstream reaches due to the removal of obstructions must be analyzed using appropriate stream geomorphologic procedures. Avoid or mitigate activities that negatively affect stability.

Debris disposal Remove cleared and snagged material from the floodplain or deposit in areas or in a manner that will not significantly affect the flow capacity of the floodplain. Designate proper locations to dispose of all debris including invasive species and where the debris will not remobilize during future flood events.

Hazardous materials Hazardous materials such as propane tanks and car bodies may be part of the debris that is to be removed. The contractor will investigate the debris in the work limit area prior to and during removal to ensure that all work is performed in a safe manner and hazardous debris is properly disposed of.

Vegetation Restore all areas denuded and/or disturbed during clearing and snag removal by planting vegetation, unless the disturbance is minimal and conditions are highly conducive for natural regeneration of vegetation. Use native vegetation where practical. Vegetation established as part of this practice should include ecologically suitable species obtained from local sources wherever practical. Take precautions to prevent introduction of invasive species. Minimize disturbance of wetlands, riparian areas, and fish and wildlife habitat sites, and avoid disturbance where possible. The establishment of vegetation on cleared and snagged areas will be in accordance with the criteria contained within NRCS Conservation Practice Standard (CPS) Critical Area Planting (Code 342).

CONSIDERATIONS

Debris in stream systems affects the physical characteristics of the stream as well as the diversity and abundance of its aquatic organisms. Fisheries and/or aquatic biologists can assist in evaluating and incorporating measures to improve aquatic and riparian-wetland habitat.

Incorporate enhancements for fish and wildlife values as needed and practical. Special attention should be given to landscape aesthetics and to protecting and maintaining key shade, food, and den trees. Use NRCS CPS Stream Habitat Improvement and Management (Code 395).

In addition to NRCS CPS Critical Area Planting (Code 342), for areas where it is difficult to establish vegetation consider NRCS CPSs Riparian Herbaceous Cover (Code 390), Riparian Forest Buffer (Code 391), Access Control (Code 472), Mulching (Code 484), Streambank and Shoreline Protection (Code 580), and Tree/Shrub Establishment (Code 612).

Retain habitat-forming elements that provide cover, food, pools, and water turbulence, to the extent possible.

Root balls of fallen trees that are securely anchored in the stream or naturally formed logjams may provide fish habitat and/or stability. The effects of these items should be included in the stream capacity hydraulic analysis. Existing root structure and stumps firmly within the soil should remain to help stabilize the soil and facilitate resprouting of woody vegetation. Erosion rates decline as a percentage of vegetative roots in a streambank increases.

Selection of appropriate riparian vegetation will increase the streambank's ability to resist future erosion.

Clearing and snagging activity may re-suspend sediments in the flow. Consider techniques that promote beneficial sediment deposition and the filtering of sediment. During construction, woody materials may float downstream and cause additional snags and drifts. Incorporate measures as needed and practical to address this concern. Schedule in-stream work to avoid environmentally sensitive periods such as spawning and migration to the fullest extent possible. Incorporate measures and practices, as needed and practical, to address modified flow conditions that adversely affect resources such as—

• A lowered hydraulic gradient that may drain adjacent flood plains more quickly.

• Decreased ground water recharge in water-losing streams resulting from reduced residence time in the stream and adjacent floodplains.

Ground-disturbing activities associated with this practice have the potential to adversely affect protected plant species and may encourage the establishment of invasive plant species. Quickly revegetating disturbed areas can minimize the introduction of nonnative species.

Temporary erosion and sediment best management practices can be used to minimize the delivery of fine sediment to adjacent and downstream reaches.

Incorporate construction methods that enhance fish and wildlife values as needed and practical to include—

• Use of hand-operated equipment, water-based equipment, or small equipment to minimize soil, water, and other resource disturbances.

• Operation of heavy machinery from atop adjacent streambanks to the fullest extent possible.

• After the material has been removed from streambank locations, limiting machinery access to riparian areas to minimize damage to stream habitat.

No special considerations have been identified for this practice.

CONSERVATION PRACTICE STANDARD

MULCHING

CODE 484 (ac)

DEFINITION

Applying plant residues or other suitable materials to the land surface.

PURPOSE

This practice is applied to achieve the following purpose(s):

- Improve the efficiency of moisture management; Reduce irrigation energy used in farming/ ranching practices and field operations; Improve the efficient use of irrigation water; Prevent excessive bank erosion from streams, shorelines, or water conveyance channels; Reduce concentrated flow erosion; Reduce sheet, rill, and wind erosion; Improve plant productivity and health; Maintain or increase organic matter content; Reduce emissions of particulate matter

CONDITIONS WHERE PRACTICE APPLIES

This practice applies to all lands where mulches are needed.

CRITERIA

General Criteria Applicable to All Purposes The selection of mulching materials will depend primarily on the purpose(s) for the mulch application, site conditions, and material availability. The mulch materials may consist of natural or synthetic materials of sufficient dimension (depth or thickness) and durability to achieve the intended purpose for the required time period. Prepare the soil surface to achieve the desired purpose. Apply the mulch material evenly. Use tackifiers, emulsions, pinning, netting, crimping, or other methods of anchoring, if needed, to hold the mulch in place for specified periods.

In cases where furrow erosion may occur due to concentrated flows from mulches(e.g., plastic mulches on beds), take appropriate measures to protect the furrows and the furrow outlets.

Apply manufactured mulches according to the manufacturer's specifications. Remove synthetic mulches from the field prior to the next crop. Do not incorporate (e.g. disk) synthetic mulches a into the soil. When mulching with wood products such as wood chips, bark, or shavings or other wood materials, apply a minimum 2-inch thickness of particles that remain in place during heavy rainfall or strong wind events, or both if applicable. The minimum size of mulching material consisting of gravel or other inorganic mulching is 0.75 inches and applied to a minimum depth of 2 inches. When mulching with cereal grain straw or grass hay, apply at a rate to achieve a minimum 70 percent ground cover. Determine the mulch rate using the current erosion prediction technology for the intended purpose. Do not apply plant-based mulch materials with a carbon (C) to nitrogen (N) ratio of less than 20:1 to watercourses.

Additional Criteria to Improve the Efficiency of Moisture Management, to Reduce

Irrigation Energy Used in Farming/Ranching Practices, and Field Operations or to Improve the Efficient Use of Irrigation Water

Apply mulch materials to cover at least 90 percent of the soil surface to reduce potential evaporation. Fine textured mulches (e.g., rice hulls) which allow less oxygen penetration than coarser materials should be no thicker than 2 inches Additional Criteria to Improve Plant Productivity and Health

When establishing vegetative cover, apply mulch at a rate that achieves a minimum of 70 percent ground cover to provide protection from erosion and runoff and yet allow adequate light and air penetration to the seedbed to ensure proper germination and emergence.

Additional Criteria to Increase Organic Matter Content

Use plant-based mulching materials of suitable quantity and quality to add organic matter, provide food and shelter for soil biota, and protect the soil surface from raindrop impact and crusting, while allowing for adequate soil aeration. An evaluation of the system using the current approved soil conditioning index (SCI) procedure results in zero or higher.

CONSIDERATIONS

Evaluate the effects of mulching on evaporation, infiltration, and runoff. Mulch material may affect microbial activity in the soil surface, increase infiltration, and decrease runoff, erosion, and evaporation. The temperature of the surface runoff may also be lowered.

Mulch materials with low permeability may adversely affect the water needs of plants.

Avoid excessively thick or tightly packed mulches that can result in soggy anaerobic conditions at the soil surface during wet weather, or prevent rainfall or overhead irrigation from reaching the soil during times of moisture deficit.

Organic materials with C:N ratios of less than 20:1 will release nitrate-nitrogen that can cause water quality impairments.

Finely divided plant residues (e.g., sawdust) and those rich in soluble carbohydrates (e.g., fresh green-chopped sorghum-sudangrass, corn, or other grasses) that have a C:N ratio greater than 30 can tie up soil N and necessitate supplemental N applications on crops. Coarser materials such as grain straw and chipped brush usually do not reduce crop-available soil N levels unless and until they are incorporated into the soil by tillage or cultivation.

Mulching may also provide habitat for beneficial organisms and provide pest suppression.

In attempting to provide habitat for ground beetles,spiders, and other predators of weed seeds and crop pests, use mulch of sufficient ground cover and suitable thickness and texture for the targets pecies. Avoid excessively thick or tightly packed mulches, which can interfere with the movement of ground beetles and other beneficial organisms, and may increase the incidence of crop pests and diseases. Consider mulching crops only if the selected mulching materials, and rates of application do not contribute to pest problems.

During the period when weed seed predation is desired and predators are most active, avoid pesticide applications or pesticide exposures that could adversely affect weed seed consumers.

Low permeability mulches (e.g., plastic) may increase concentrated flow and erosion on unmulched areas.

Light-reflecting mulches such as white or aluminized plastic film or bright straw can repel some pests.

Consider potential beneficial or detrimental effects of mulching materials on the biotic community surrounding the crop, including beneficial soil micro- and macro-organisms, as well as plant pathogens and plant pests. These effects are specific to site, mulch, and crop, and may include enhanced soil microbial activity, increased or reduced levels of crop diseases, and toxic (allelopathic) activity against the crop, weeds, or other beneficial or pest organisms.

Keep mulch 3 to 6 inches away from plant stems and crowns to prevent disease and pest problems. Additional weed control may be needed around the plant base area.

Deep mulch provides nesting habitat for ground-burrowing rodents that can chew extensively on tree trunks and tree roots. Light mulch applied after the first cold weather may prevent rodents from nesting.

Some mulch material may adversely affect aquatic environments through changes in water chemistry or as waterborne debris. Consider placing mulch in locations that minimizes these risks. Consider potential effects of soil physical, chemical and biological properties. Refer to soil survey data as a preliminary planning tool for assessment of areas. Consult a resource soil scientist or the Web Soil Survey at: http://websoilsurvey.nrcs.usda.gov/app/ to obtain soil properties and qualities information.

For all organic or transitioning to organic operations, follow all National Organic Program (NOP) rules.

BEST MANAGEMENT PRACTICES (BMP)

HEAVY EQUIPMENT & EARTH-MOVING ACTIVITIES

HEAVY EQUIPMENT OPERATION PROBLEMS

SOIL EXCAVATION AND GRADING OPERATIONS OFTEN CONTRIBUTE TO RUNOFF

POLLUTION. BY LOOSENING LARGE AMOUNTS OF SOIL AND SEDIMENT, EARTH-MOVING

ACTIVITIES CAN CAUSE SEDIMENT TO FLOW INTO GUTTERS, STORM DRAINS, AND

STREAMS. SEDIMENT IS THE MOST COMMON POLLUTANT WASHED FROM WORK SITES,

CREATING MULTIPLE PROBLEMS WHEN IT ENTERS THE STREAM. SEDIMENT CLOGS THE

GILLS OF FISH, BLOCKS THE TRANSMISSION OF LIGHT, AND INCREASES STREAM WATER

TEMPERATURE, ALL OF WHICH HARM LIFE, DISTURBING THE FOOD CHAIN UPON WHICH

BOTH FISH AND PEOPLE DEPEND UPON. SEDIMENT ALSO CARRIES WITH IT OTHER WORK

SITE POLLUTANTS SUCH AS PESTICIDES, CLEANING SOLVENTS, CEMENT WASH, ASPHALT

AND CAR FLUIDS LIKE MOTOR OIL, GREASE AND FUEL. THUS, POORLY MAINTAINED

VEHICLES AND HEAVY EQUIPMENT LEAKING FUEL AND OIL AT THE CONSTRUCTION SITE,

CONTRIBUTING TO POLLUTION.

SOLUTIONS BEST MANAGEMENT PRACTICES (BMP) SUCH AS HANDLING, STORING, AND

DISPOSING OF MATERIALS PROPERLY CAN PREVENT POLLUTANTS FROM ENTERING THE

STORM DRAINS.

GENERAL BUSINESS PRACTICES SCHEDULE EXCAVATION AND GRADING WORK FOR

DRY WEATHER. USE AS LITTLE WATER AS POSSIBLE FOR DUST CONTROL.

CLEAN UP SPILLS NEVER HOSE DOWN "DIRTY" PAVEMENT OR IMPERMEABLE SURFACES

WHERE FLUIDS HAVE SPILLED. USE DRY CLEANUP METHODS (SAWDUST OR RAGS) AND

DISPOSE PROPERLY. SWEEP UP AND DRY SPILLED MATERIALS IMMEDIATELY. NEVER

ATTEMPT TO BURY THEM OR WASH THEM AWAY WITH WATER. CLEAN UP SPILLS ON

DIRT AREAS BY DIGGING UP AND DISPOSING OF CONTAMINATED SOILS. REPORT

SIGNIFICANT SPILLS TO THE APPROPRIATE SPILL RESPONSE AGENCIES IMMEDIATELY.

VEHICLE AND EQUIPMENT MAINTENANCE MAINTAIN ALL VEHICLE AND HEAVY

EQUIPMENT IN GOOD WORKING ORDER AND INSPECT FREQUENTLY FOR LEAKS.

CONDUCT ALL VEHICLE/EQUIPMENT MAINTENANCE AND REFUELING AT ONE LOCATION

THAT IS AWAY FROM STORM DRAINS. PERFORM MAJOR MAINTENANCE, REPAIR JOBS,

AND VEHICLE/EQUIPMENT WASHING OFF-SITE. USE GRAVEL APPROACHES WHERE TRUCK

TRAFFIC IS FREQUENT, TO REDUCE SOIL COMPACTION AND LIMIT THE TRACKING OF

SEDIMENT INTO THE STREET. USE DRIP PANS OR DROP CLOTHS TO CATCH DRIPS AND

SPILLS IF YOU DRAIN AND REPLACE MOTOR OIL, RADIATOR COOLANT, OR OTHER FLUIDS

ON SITE. COLLECT ALL USED FLUIDS, STORE IN SEPARATE CONTAINERS, AND RECYCLE

WHENEVER POSSIBLE. DO NOT USE DIESEL OIL TO LUBRICATE EQUIPMENT OR PARTS.

EROSION PREVENTION AFTER CLEARING, GRADING OR EXCAVATING, EXPOSED SOIL

POSES A CLEAR AND IMMEDIATE DANGER FOR STORMWATER POLLUTION.

REVEGETATION (TEMPORARY OR PERMANENT) IS AN EXCELLENT FORM OR EROSION

CONTROL FOR ANY SITE. AVOID EXCAVATION AND GRADING ACTIVITIES DURING WET

WEATHER. CONSTRUCT DIVERSION DIKES TO CHANNEL RUNOFF AROUND THE SITE. LINE

CHANNELS WITH GRASS OR ROUGHENED PAVEMENT TO REDUCE RUNOFF VELOCITY.

COVER STOCKPILES AND EXCAVATED SOIL WITH SECURED TARPS OR PLASTIC SHEETING.

REMOVE EXISTING VEGETATION ONLY WHEN ABSOLUTELY NECESSARY. LARGE PROJECTS

SHOULD BE CONDUCTED IN PHASES. CONSIDER PLANTING TEMPORARY VEGETATION

FOR EROSION CONTROL ON SLOPES WHERE CONSTRUCTION IS NOT IMMEDIATELY

PLANNED. PLANT PERMANENT VEGETATION AS SOON AS POSSIBLE, ONCE EXCAVATION

AND GRADING ACTIVITIES ARE COMPLETE.

VEHICLE FUELING VEHICLE EQUIPMENT FUELING PROCEDURES AND PRACTICES ARE

DESIGNED TO PREVENT FUEL SPILLS AND LEAKS, AND REDUCE OR ELIMINATE

CONTAMINATION OF STORMWATER. THIS CAN BE ACCOMPLISHED BY USING OFFSITE

FACILITIES, FUELING DESIGNATED AREAS ONLY, ENCLOSING OR COVERING STORED FUEL,

IMPLEMENTING SPILL CONTROLS, AND TRAINING EMPLOYEES AND SUBCONTRACTORS

IN PROPER FUELING PROCEDURES.

SUITABLE APPLICATIONS THESE PROCEDURES ARE SUITABLE ON ALL CONSTRUCTION

SITES WHERE VEHICLE AND SITES WHERE VEHICLE AND EQUIPMENT FUELING TAKES

PLACE. ONSITE VEHICLE AND EQUIPMENT FUELING SHOULD ONLY BE USED WHERE IT IS

IMPRACTICAL TO SEND VEHICLES AND EQUIPMENT OFFSITE FOR FUELING. SENDING

VEHICLES AND EQUIPMENT OFFSITE SHOULD BE DONE IN CONJUNCTION WITH CO,

STABILIZED CONSTRUCTION ENTRANCE/EXIT.

IMPLEMENTATION USE OFFSITE FUELING STATIONS AS MUCH AS POSSIBLE. THESE

BUSINESSES ARE BETTER EQUIPPED TO HANDLE FUEL SPILLS PROPERLY. PERFORMING

THE WORK OFFSITE CAN ALSO BE ECONOMICAL BY ELIMINATING THE NEED FOR A

SEPARATE AREA AT THE WORK SITE. DISCOURAGE "TOPPING OFF OF FUEL TANKS.

Natural Resources Conservation Service

CONSERVATION PRACTICE STANDARD

CRITICAL AREA PLANTING

CODE 342 (ac)

DEFINITION

Establishing permanent vegetation on sites that have, or are expected to have, high erosion rates, and on sites that have physical, chemical, or biological conditions that prevent the establishment of vegetation with normal seeding/planting methods.

PURPOSE

This practice is used to accomplish one or more of the following purposes:

• Stabilize areas with existing or expected high rates of soil erosion by wind or water

• Stabilize stream and channel banks, pond and other shorelines, earthen features of structural conservation practices

• Stabilize areas such as sand dunes and riparian areas

CONDITIONS WHERE PRACTICE APPLIES

This practice applies to highly disturbed areas such as --

• Active or abandoned mined lands.

• Urban restoration sites.

• Construction areas.

• Conservation practice construction sites.

•Areas needing stabilization before or after natural disasters such as floods, hurricanes, tornados, and wildfires.

• Eroded banks of natural channels, banks of newly constructed channels, and lake shorelines. Other areas degraded by human activities or natural events.

CRITERIA: General Criteria Applicable to All Purposes

Site preparation

Conduct a site investigation to identify any physical, chemical, or biological conditions that could affect the successful establishment of vegetation.

Clear areas to be planted of unwanted materials and smooth or shape, if needed, to meet planting purpose(s).

Prepare a suitable seedbed for all seeded species. Rip compacted layers and re-firm the soil prior to seedbed preparation, as needed.

As site conditions dictate, when grading slopes, stockpile topsoil to be redistributed over area to be planted.

Species selection

Select species for seeding or planting that are suited to local site conditions and intended uses, and common to the site or location.

Selected species will have the capacity to achieve adequate density and vigor to stabilize the site within an appropriate period.

Establishment of vegetation.

Plant seeds using the method or methods best suited to site and soil conditions.

Limit sod placement to areas that can naturally supply needed moisture or sites that can be irrigated during the establishment period. Place and anchor sod using techniques to ensure that it remains in place until established.

Specify species, rates of seeding or planting, legume inoculation, minimum quality of planting stock (e.g., pure live seed (PLS) or stem caliper), method of seedbed preparation, and method of establishment before application. Use only viable, high-quality seed or planting stock.

Seed or plant at a time and in a manner that best ensures establishment and growth of the selected species.

Plant during approved times for the species to be used.

Apply soil amendments (e.g., lime, fertilizer, compost) according to the requirements in the local Field Office Technical Guide.

Mulch or otherwise stabilize (e.g., polyacrylamide (PAM)) plantings as necessary to ensure successful establishment.

Additional Criteria to Stabilize Stream and Channel Banks, Pond and Other Shorelines, Earthen Features of

Structural Conservation Practices Bank and channel Slopes

Shape channel side slopes so that they are stable and allow establishment and maintenance of desired vegetation.

A combination of vegetative and structural measures may be necessary on slopes steeper than 3:1 to ensure adequate stability.

Species selection. Plant material used for this purpose must --

• Be adapted to the hydrologic zone into which they will be planted.

• Be adapted and proven in the regions in which they will be used.

• Be compatible with existing vegetation in the area.

• Protect the channel banks but not restrict channel capacity.

Establishment of vegetation.

Specify species, planting rates, spacing, methods and dates of planting based on local planting guides or technical notes. Identify and protect desirable existing vegetation during practice installation.

Use a combination of vegetative and structural practices with living and inert material when flow velocities, soils, and bank stability preclude stabilization by vegetative establishment alone. Use Conservation Practice Standard (CPS) Streambank Stabilization (Code 580) for the structural measures.

Control existing vegetation on a site that will compete with species to be established vegetatively (e.g.. bare-root, containerized, ball-and-burlap, potted) to ensure successful establishment of the planted species.

Plant streambank stabilization vegetation in accordance with the NRCS Engineering Field Handbook Part 650, Chapter 16, "Streambank and Shoreline Protection," and Chapter 18, "Soil Bioengineering for Upland Slope Protection & Erosion Reduction."

Site protection and access control. Restrict access to planted areas until fully established.

Additional Criteria to Stabilize Areas Such As Sand Dunes and Riparian Areas Plants for sand dunes and coastal sites must be able to survive being buried by blowing sand, sand blasting, salt spray, salt water flooding, drought, heat, and low nutrient supply. Include sand trapping devices such as sand fences or brush matting in the revegetation/stabilization plans where applicable.

CRITICAL AREA PLANTING CODE 342 (continued)

Establishment of vegetation.

Site protection and access control.

Restrict access to planted areas until fully established.

Additional Criteria to Stabilize Areas Such As Sand Dunes and Riparian Areas

Plants for sand dunes and coastal sites must be able to survive being buried by blowing sand, sand blasting, salt spray, salt water flooding, drought, heat, and low nutrient supply.

Include sand trapping devices such as sand fences or brush matting in the revegetation/ stabilization plans where applicable.

CONSIDERATIONS

Species or diverse mixes that are adapted to the site and have multiple benefits should be considered. Native species may be used when appropriate for the site.

To benefit pollinators and other wildlife, flowering shrubs and wildflowers with resilient root systems and good soil-holding capacity also should be considered for incorporation as a small percentage of a larger grass-dominated planting. Where appropriate consider a diverse mixture of forbs to support pollinator habitat.
