The survey shall include the following species: Pepperweed (Lepidium latifolia), Exotic Common Reed (Phragmites australis), and Iceplant (Carpobrotus edelus), Himalayan Blackberry (Rubus armenius), Fennel (Foeniculum vulgare), Giant Reed (Arundo donax), Salt Cedar (Tamarix ramosissima), Star Thistle (Centaurea solstitialis), and exotic species found onsite that are define in the ‘high’ category in the California Invasive Plant Council (Cal-IPC) or plant species not named here that appear to dominate the native species at the project site.

The Cal-IPS website: http://www.cal-ipc.org

The Contractor shall measure the total area of all invasives and exotic weeds indicated in the HRP and create a table showing date sampled, transect identifier, area (in square feet), area as percent of total site, and trends of target plants. The Contractor shall label all of the polygons (GIS instrument) for each of the

P a g e | 12 plant species. The Contractor shall have the polygons identified per each species and have the polygons (shape files) inserted into a Computer Aided Drafting (CAD) program, with an outline of the project site.

An AutoCad version 14 file .dwg AND .kmz format. The polygons generated by the GIS shall include aerial imagery and be submitted to the COR yearly.

Native Water Emergent Plant Survey: Survey shall include the zone that is set aside for Habitat Restoration Salvage (Fig 4E). Within this zone, the Contractor shall identify the water emergent species present within the 1.32 are zone, and record the number of salvaged plant massing’s showing species, original amount transplanted and current survival rates.

6.2.7. Layout: Evenly spaced grid planting of salvaged plant material in area shown in Exhibit B, Figure 4E.

6.2.8. Seeding Grass: Do not disk or disturb the soil in preparation for grass seeding, however, mow all herbaceous growth close to soil prior to seeding. Apply grass seed to the entire upland and buffer area of the project sites. Perform grass seeding using the no-till drill seeding method. To meet SWPPP compliance, reseed as necessary to meet 70% SWPPP vegetative coverage compliance by the end of the first year after seeding. Native grass establishment must comply with the performance standards indicated in Attachment E Section 32 92 33 Grass Seeding and Erosion Control requirements. For grass seed mixtures, see Attachment C Plant Schedule and Exhibit B for seeding locations.

6.2.9. Providing Water: Design, provide, deliver, store, operate and maintain all water components, including water source, electrical power, equipment, and materials. Provide and deliver water to all plants as needed. See Attachment C for Planting Schedules.

6.2.10. Laying out Plant Locations: Prior to planting and/or placing salvage plantings, layout and flag plant locations on the ground for grid planting layout for salvage and intertidal. Evenly space plant locations along within grid. Coordinate and adjust plant locations as per the Contracting Officer and obtain his/her approval prior to installing any plants. See Attachment C, Plant Schedule in conjuncture with Exhibit B, HRP.

6.2.11. Planting Pits: Excavate a plant pit capable of supporting each size of salvaged and/or containerized plant where the flag locations have been placed. Dig each planting pit to the depth of the plant’s root ball and twice as wide. All locations must be pre-flagged and cleared by XO prior to any ground disturbance.

6.2.12. Salvage/Store Water Emergent Plants: Provide and install all container and salvaged plants, at the locations flagged, for the species and at the amounts as indicated within this Contract. Keep woody plants 15 feet from site perimeter and any designated interior maintenance roads. For all woody plants, provide browse guard (1/2 gallon milk carton or similar), gopher cage, stake, geotextile fabric mulch, slow-release commercial grade free-flowing fertilizer appropriate for the plant and soil characteristics with proximity to water. Provide fertilizer product data to Contracting Officer for review prior to work. Place a stake inside the browse guard to keep the guard upright and so that birds can use it to climb out. Water basin are not required, however manipulate soil around plant so that all the water from the emitter is contained and soaks into the soil before it flows away from the root zone of the plant. Water-in all plants within 12 hours of installation. Refer to Attachment F, Submittal Register for plant installation submittal requirements.

See Attachment C, Plant Schedule for plant container sizes, quantities, and densities.

6.2.13. Watering: Hand water in plants after installation. No watering of restoration area or upland/buffer area of site shall occur during establishment period.

6.2.14. Weeding: Within one month of the first herbicide spraying, remove blackberry brambles, Giant Reed, Star Thistle, Salt Cedar, Ice plant, etc. as identified in HRP.

P a g e | 13

Weeding is to occur and generally timed following the latest rains that generate growth. For each Establishment Period year (EP) provide the following:

• Base Year Weeding: 6 times throughout year as needed.

• EP1 Weeding: 4 times throughout the year as needed.

• EP2 Weeding: 3 times throughout the year as needed

6.2.15. Mechanical Vegetation Controls: Cut back weeds, native grasses, and dead plant material. Keep a fire suppressor water system, such as a trailered water tank with a motor-generated water hose, onsite and near the work area wherever mowing and other hazardous activities are being performed. Provide the following:

• Base Contract Mechanical Controls: 6 times, timed and spaced to capture growth throughout the season. Mechanically control target noxious and invasive weeds to promote target species growth.

• EP1 Mechanical Controls: 6 times, timed and spaced to capture growth throughout the season.

Mechanically control target noxious and invasive weeds to promote target species growth.

• EP2 Mechanical Controls: 6 times, timed and spaced to capture growth throughout the season.

Mechanically control target noxious and invasive weeds to promote target species growth.

6.2.16. Herbicide Application: The herbicide application program shall be developed to remove highly invasive species from the project site. All application of herbicide must follow the approved Weed Control Plan. Prevent herbicide overspray and wind drift into non-target and planted areas. Additionally, when spraying herbicide, apply enough to cover plant yet minimize herbicide coming in contact with the soil. Do not spray when wind will carry spray to non-target areas. Do not spray when warm weather can volatilize herbicide and cause damage to non-target areas. Utilize low pressure drift resistant spray nozzles, anti-drift agents, spray shields and any other means necessary to ensure non-target areas are not damaged by overspray and wind drift. To accomplish this, the efforts required herein are to reduce and eliminate the non-native exotic grass and broadleaf herbaceous vegetation and accompanying seed banks while enhancing native species establishment. Select the appropriate herbicide designed to kill all non-native grasses and undesirable exotic growth, including all vegetative growth that occurs onsite, on the maintenance road, and within the staging area and site edges. Prevent annual grasses from setting viable seed, keep broadleaf weeds under 6” in height. When the staging area is removed and no longer in use, seed its entire area and establish native grass prior to leaving. All spraying must be performed by a certified applicator for the type of herbicide used. Place proper notifications at adjacent public roads/trails two days prior to spraying operations. Weed eradication for species indicated in the HRP is required by the contractor to 95% of the total site area.

• All herbicides shall be applied in accordance with local, state, and federal regulations and regulations set by the California Department of Pesticide Regulation and the MOTCO IPMP according to labeled instruction. Care shall be taken to avoid contact with any native vegetation, and foliar applications shall only be employed on calm days when winds are below 5 miles/hour.

If winds above 5MPH, written approval much be given by COR.

• Herbicide treatments shall be conducted under the supervision of a State of California- licensed Pest Control Advisor. Herbicide applications shall be made by a Licensed Pesticide Applicator.

• Herbicide treatments shall be selectively applied to target species to the maximum extent possible.

• Herbicide treatments in the tidal marsh shall be timed to coincide with the ebb tide, and to the extent feasible, shall be conducted during tidal cycles that maximize the area that will not be inundated within 24 hours of herbicide application.

Provide herbicide product and equipment data to COR for review prior to work. Refer to Attachment F, Submittal Register. Spray applications are defined as follows:

6.2.16.1 Spraying: “Noxious / Invasive Herbicide Spraying” is defined as the initial and ongoing site spraying prior to ground disturbance and throughout establishment period. Application of herbicide is designed to kill and reduce the existing non-native, invasive, and exotic competition

P a g e | 14 to preserve and foster growth native and indigenous species. Areas that have abundant amounts of desirable existing natives that are to remain. The goal is to retain the existing natives and remove noxious and invasives to 95% noxious and invasive free. Follow guidance in the HRP, attached.

• “Spot Spraying” is defined herein as spraying and killing targeted undesirable broadleaf vegetation or non-native exotic as defined in the HRP. Prior to spot spraying, coordinate the goals with the Contracting Officer. Spray all targeted undesirable vegetation with a non-selective herbicide designed to completely kill the targeted existing vegetation or a selective herbicide to target specific weed and non-native grass species.

The application quantities for spraying are as follows:

• IP Grass Treatment Spraying: : 6 times; time spraying to capture weed growth over entire site

• EP1 Spraying: timed and spaced to capture growth.

o Rows: 4 times o Middles: 2 times o Pre-seeding spraying: 1 time o Spot Spraying: 8 times

• EP2 Spraying: timed and spaced to capture growth.

o Rows: 3 times o Spot Spraying: 9 time

6.2.17. Surveying Plants: Contractor must provide quarterly survival reports from transects indicated in the HRP along with annual survivorship reports to the CO. Include discussion for success and shortfalls, BMPs implemented, species richness, natural recruitment, and other pertinent site and restoration information critical to projects success. Present the results in each of the subsequent annual reports. See Attachment F, Submittal Register and section 6.2.20 for details.

6.2.18. Replacing Dead Plants & Missing Plants (from tidal and/or waterfowl): At the end of the first and second year establishment periods replace all dead plants, including using new browse guards, fertilizer, and mulch of like material, size and type as was originally installed. Coordinate species with the Contracting Officer prior to ordering plant material. Since some species are not always readily available at a local nursery, anticipate in advance those species that may need to be replaced and pre-grow the plants so they are at the required container size and ready when needed. Due to unavailability or poor species performance, adjustments to replacement species may be desirable and accepted, provided coordination has been performed with the Contracting Officer in advance and a written approval of species substitutions has been issued.

6.2.19. Preparing Activity Records: Prepare activity records, which include monthly records of work performed during each month of the contract, as-built drawings of all installation work, and a weed control plan for each year of the contract.

• Prepare monthly activity records, one for each month of the Contract. Submit the monthly activity record with each invoice, addressing specific tasks billed. Include activities of all installation and maintenance work that is performed throughout each preceding month of the contract. Submit record along with each monthly invoice, within 7 working days following the end of each month.

Each monthly record must not be longer than one page on 8-1/2”x11” format.
