IN FLINT PEN STRAND

July 2026

This document includes the technical specifications associated with the bid request for the services detailed below at the Southwest Florida International Airport Airport Mitigation Park.

The objective of the work is to treat exotic and nuisance species in the areas identified within Flint

Pen Strand.

1.0 Project Summary

This bid request is for the treatment of exotic and nuisance vegetation species within the

Flint Pen Strand management unit of the Airport Mitigation Park (Exhibit 1). The treatment areas are as follows (Exhibit 2):

• Treatment Area A: 283.62± acres

• Treatment Area B – Spring: 245.85± acres

• Treatment Area C – Winter Mechanical Removal: 7.27± acres

• Treatment Area C – Winter Mow: 43.27± acres

• Treatment Area D – Spring (Post-Mow/Mechanical Removal): 50.54± acres

All treatments are one-time events.

The treatments include all Florida Invasive Species Council (FISC) exotic species within the bid treatment area, including but not limited to species such as melaleuca (Melaleuca quinquenervia), Brazilian pepper (Schinus terebinthifolia), torpedograss (Panicum repens), Wright’s nutrush (Scleria lacustris), West Indian marsh grass (Hymenachne amplexicaulis), caesarweed (Urena lobata), climbing cassia (Senna pendula), Old World climbing fern (Lygodium microphyllum), earleaf acacia (Acacia auriculiformis), cogongrass (Imperata cylindrica), Peruvian primrosewillow (Ludwigia peruviana), natalgrass (Melinis repens), spermacoce (Borreria verticillata), and missiongrass (Cenchrus polystachios). In addition, those species listed in Table 1 will be targeted where found and/or where vines encroach the tree canopy. Bahiagrass (Paspalum notatum) and smutgrass (Sporobolus indicus) are not included in this scope.

-2-

The Notice to Proceed (NTP) for work to be conducted will depend on approval of funding by the Owner (i.e., Lee County Port Authority (LCPA)) for that specific year. The LCPA reserves the right to release a portion of the work, or none of the work, during any given fiscal year, dependent upon the availability of funds for the fiscal year. The contracted work under the bid will be for a one-time treatment event within the bid treatment area.

Provided there are no schedule delays due to weather conditions or other situations outside of the Sub-Contractor’s control, the anticipated start date for the work under the bid will be after the NTP is issued on November 20, 2026. Any work performed under this contract shall follow the schedule in the contract (Table 2). Woody/shrubby vegetation may be treated at any time during the treatment schedule. Any basal treatments of woody vegetation shall be completed early enough in the treatment process to allow the chemicals to take effect before final inspection and sign-off is requested. Herbaceous vegetation should only be treated when actively growing (i.e., non-dormant) and during periods of low or no standing water, thereby maximizing the effectiveness of the applied herbicides. Herbaceous vegetation should be treated only when environmental conditions (e.g., temperature, rainfall, soil moisture) and signs of active growth

(e.g., green shoots, seeds sprouting) indicate that the targeted species are actively growing and can be effectively eradicated. Additional details are provided under Section 4.0.

The treatment schedule depends upon weather conditions and on-site water levels. The treatment schedule may be adjusted upon agreement between the Sub-Contractor and the Owner, provided adequate notice is given before the due date. Successful completion will be determined by the Owner and the General Environmental and Planning Consultant (GEPC). Exotic and nuisance species to be treated, treatment schedules, and other details regarding the work are provided below.

2.0 Project Description

The Flint Pen Strand portion of Airport Mitigation Park is located in Sections 13, 14, and

23; Township 46 South; Range 26 East; Lee County; Florida (Exhibit 1).

The project consists of the following one-time treatments: Treatment A (of exotic and nuisance species); Treatment B – Spring (of exotic and nuisance species); Treatment C – Winter

Mechanical Removal (of nuisance shrubs and exotic and nuisance species); Treatment C – Winter

Mow (of exotic and nuisance species); and Treatment D – Spring (Post-Mow/Mechanical

-3-

Removal) (of exotic and nuisance species following mowing and mechanical removal). Treatments will include all indicated targeted exotic and nuisance species within the designated treatment areas of Flint Pen Strand. The treatment areas for Treatment A (283.62± acres), Treatment B (245.85± acres), Treatment C (Winter Mechanical Removal) (7.27± acres), Treatment C (Winter Mow)

(43.27± acres), and Treatment D – Spring (Post-Mow/Mechanical Removal) (50.54± acres) are depicted on Exhibit 2. A more detailed description of these treatment areas is provided in

Section 4.0, below.

3.0 Bid Description

The bid is for the treatment of all Categories I and II exotic and nuisance plant species listed on the most current FISC List of Invasive Plant Species (Exhibit 3), where applicable, and those plant species from Table 1 within Treatment Area A (Areas A-1 through A-14, 283.62± acres); Treatment Area B – Spring (Areas B-1 through B-6, 245.85± acres); Treatment

Area C – Winter Mechanical Removal (Area C-1, 7.27± acres); Treatment Area C – Winter Mow

(Area C-1, 43.27± acres); and Treatment Area D – Spring Treatment (Post-Mow/Mechanical

Removal) (Areas D-1 and D-2, 50.54± acres), as described below in Section 4.0.

Melaleuca, Brazilian pepper, torpedograss, Wright’s nutrush, West Indian marsh grass, natalgrass, missiongrass, caesarweed, climbing cassia, Old World climbing fern, Java plum

(Syzygium cumini), earleaf acacia, cogongrass, and Peruvian primrosewillow are the primary exotic species to be treated. Vine species such as Old World climbing fern, greenbrier (Smilax spp.), and grapevine (Vitis spp.) that are observed in dense growths where they encroach the canopy of mature trees shall be poodle-cut and treated as well. Dense growth refers to growth that is encroaching on the tree canopy in such a way that the vine is visible on or through the tree canopy foliage (i.e., the crown) or just below the crown. Except for Old World climbing fern, dense mats of vines growing along the ground are not included in this scope. Bahiagrass and smutgrass are also not included in this scope.

The bid includes all personnel, equipment, chemicals, and any other materials necessary to efficiently complete the contracted work. All bid treatment areas under contract must contain zero percent areal coverage of exotic species, as defined in Section 4.0. Extreme care should be taken to avoid impacts to the existing native vegetation and ground surface from equipment used to perform the treatment and removal work.

4.0 Technical Specifications

The bid consists of one-time treatments of exotic and nuisance species listed in the most current FISC List of Invasive Plant Species (Exhibit 3) and those species listed in Table 1 within

Treatment Areas A, B, and D; a one-time mechanical removal event within Treatment Area C

(Winter Mechanical Removal); and a one-time mow event within Treatment Area C (Winter

Mow). Additional details on the treatment events are provided below in this section.

Treatment Area A

This treatment area includes a higher percentage of exotic and nuisance vegetation that can be treated closer to the NTP than the other treatment areas in this bid (Exhibit 2). As a result, much of Treatment Area A can be treated year-round, and treatment of these areas may begin closer to the NTP in Table 2. Treatment Area A (particularly within areas including, but not limited to, Areas A-1 through A-5) also includes wetland habitats that may not be treated for longer periods of the treatment window due to high water levels. In these areas, herbaceous vegetation should be treated only when low water levels or no standing water is present and vegetation is actively growing (i.e., non-dormant) to maximize the effectiveness of the applied herbicides. Treating these portions of Treatment Area A before water levels recede may necessitate re-treatment, since certain exotics may not be visible or otherwise viable (i.e., of the appropriate height/age) for treatment. However, exotic and/or nuisance vegetation (e.g., Old World climbing fern) may be treated when water levels are high if high water levels will not decrease the efficacy of the treatment. Although Treatment Area A contains some of the same species as Treatment Area B

(described below), the mix of species does not justify a Spring treatment.

Treatment Area B – Spring

Treatment Area B encompasses wetland habitats where exotic and nuisance species (e.g., Wright’s nutrush, torpedograss, and caesarweed) have been documented at varying infestation levels. Treatment B shall occur when seedlings and resprouts of herbaceous species reach a minimum height of four to six inches and per the treatment schedule in Table 2 below. The intended time frame for Treatment B aligns with the spring flush of invasive herbaceous species, such as Wright’s nutrush, which typically occurs between April and June. These species are often dormant between late fall and winter ,when treatment could otherwise begin for this bid, evidenced

-5-only by the presence of dead, senesced vegetation from the previous year. The goal is to treat these species, along with any other invasive species present (i.e., caesarweed, torpedograss, etc.), when the seeds from last year’s plants have sprouted, new growth is observed, and the new plants are tall enough to successfully respond to treatment.

Within Treatment Area B, the diversity of exotic and nuisance species varies depending on site-specific conditions of a particular treatment area (e.g., Area B-1) and the biology of the plant species. For example, the primary exotic species is caesarweed within Area B-5; torpedograss within Area B-6; and torpedograss, Wright’s nutrush, and caesarweed within Area B-4. There are also other exotic and nuisance species present within these and other Treatment B areas, such as climbing cassia, Brazilian pepper, West Indian marsh grass, etc. But overall, the mix of exotic and nuisance species within Treatment Area B is expected to benefit more from a spring treatment versus Treatment Area A.

The Sub-Contractor shall notify the GEPC and the LCPA before beginning Treatment B, and they shall also provide photographic documentation of the height of the species to be treated, such as Wright’s nutrush. The GEPC shall then inspect Treatment Area B to determine if the exotic vegetation is at the appropriate height to begin treatment. These areas may be treated only after the

Sub-Contractor has received approval from the GEPC and the LCPA. Please note that Treatment

Area B consists primarily of herbaceous and forested wetland habitat types (i.e., freshwater marsh and cypress forest).

Treatment B is intended to treat species (e.g., Wright’s nutrush) following the spring flush but before those new plants themselves produce seeds. Due to site conditions and biology, some species (e.g., torpedograss and caesarweed, respectively) may have already gone dormant or to seed before treating at this stage is feasible (i.e., in the fall before NTP). Treatment B represents the next most optimal time to treat, in these cases.

Treatment Area C

Winter Mechanical Removal

Treatment C (Winter Mechanical Removal) will target high concentrations of exotic and nuisance vegetation (e.g., caesarweed) and dense native, shrubby vegetation

(e.g., wax myrtle (Morella cerifera)) that is considered overgrown and may serve as a potential fuel source within Flint Pen Strand (Exhibit 2). This mechanical treatment (i.e., -6-mulching/mowing) is intended to reduce the vegetative biomass of exotic, nuisance, and native shrubby vegetation to allow for a more effective herbicide application (i.e., Treatment D, described below), as well as to reduce the likelihood of damaging wildfires.

Native shrubs to be mechanically reduced primarily include wax myrtle, but other species such as myrsine (Myrsine cubana), cabbage palm (Sabal palmetto), and saw palmetto

(Serenoa repens) may be encountered. Treatment C must be completed a minimum of four weeks before Treatment D, or with adequate time for effective treatment to be observed and regrowth (i.e., seedlings and resprouts) of herbaceous species to reach a minimum height of four to six inches. Similar treatment regimes have proven effective in reducing exotic, nuisance, and native shrubby vegetation cover within Airport Mitigation Park in the past. Because this treatment is intended to reduce shrubby vegetation, native trees (e.g., slash pine (Pinus elliottii) and bald cypress (Taxodium distichum)) shall be avoided to the greatest extent possible. As with the other areas of this contract, the material treated does not need to be hauled off-site.

Use of a dedicated low-impact forestry mulcher or a rubber-track skid-steer with a

Gyro-Trac, FECON®, or equivalent mulching head will be allowed. Mowing is permissible in Treatment Area C (Mechanical Removal), but given the presence of shrubby vegetation, mulching is the preferred treatment. Alternate methods may be used once reviewed and approved by the LCPA and the GEPC. Mechanical removal shall only begin when site conditions are dry enough that mobilizing and using the mower will not cause rutting within the treatment area and surrounding wetland environments.

Winter Mow

Treatment C (Winter Mow) will target high concentrations of exotic and nuisance herbaceous species (e.g., torpedograss and caesarweed) within an area that can more readily be mowed than other areas within Flint Pen Strand (Exhibit 2). Mowing is expected to expose the sprouting portions of the plants (e.g., rhizomes and stolons) and seedlings, allowing for a more effective uptake of herbicide. To increase the efficacy of the treatment, herbicide (i.e., Treatment D, described below) will be applied after mowing. Treatment C must be completed a minimum of four weeks before Treatment D, or with adequate time for effective treatment to be observed and herbaceous regrowth (i.e., seedlings and resprouts) to reach a minimum height of four to six inches. Similar treatment regimes have

-7-proven effective in reducing exotic and nuisance herbaceous vegetation cover within

Airport Mitigation Park in the past. Within Treatment Area C, there are widely scattered sub-canopy (e.g., saw palmetto) and canopy (e.g., slash pine) species that are not to be mowed and shall be avoided to the greatest extent possible. This is because this treatment is intended to mow herbaceous exotic and nuisance species. Mowing shall only begin when site conditions are dry enough that mobilizing and using the mower will not cause rutting within the treatment area and surrounding wetland environments.

Treatment Area D – Spring Treatment (Post-Mow/Mechanical Removal)

Treatment D includes the treatment of exotic and nuisance herbaceous vegetation and shall occur when seedlings and resprouts reach a minimum height of four to six inches and per the treatment schedule in Table 2. Treatment D is intended to occur in spring when plants are actively growing and have reached the appropriate height to be treated following Treatment C (i.e., Winter

Mechanical Removal and Winter Mow). Prior to beginning Treatment D, the Sub-Contractor shall notify the GEPC and LCPA of their intentions to begin and provide photographic documentation of the height of the species to be treated, namely torpedograss and caesarweed. The GEPC shall then inspect Treatment Area D to determine if the exotic and nuisance vegetation is of the appropriate height to begin treatment. These areas may be treated only after the Sub-Contractor has received approval from the GEPC and the LCPA.

Treatments shall be completed within the limits of the treatment area identified in

Exhibit 2. Exotic and nuisance vegetation treatments shall not extend beyond the property limits

(perimeter fence); however, herbicide treatments shall be applied to exotic vegetation growing on the fence as applicable. Where treatment areas abut portions of the perimeter fence near Burgundy

Farms (Exhibit 2), the Sub-Contractor shall not be responsible for the vegetation maintenance in the applicable areas (i.e., within 15 feet of the interior of the perimeter fence). Similarly, treatment shall not occur within 50 feet of either side of the centerline of the existing Airport Mitigation Park trail system, as depicted in Exhibit 2. This work (i.e., maintaining the perimeter fence vegetation and trail system) is described within Technical Specifications provided under separate cover for another project. Targeted plant species to be treated include all observed species listed as Category

I and Category II invasive exotics on the most current FISC List of Invasive Plant Species (Exhibit

-8-

3) and those species found in Table 1 below. Bahiagrass and smutgrass are not included in this scope.

Table 1. Nuisance Plant Species to be Treated

Common Name Scientific Name Cattail Typha spp.

Common reed Phragmites australis Climbing hempvine Mikania scandens Dog fennel Eupatorium capillifolium Grapevine Vitis spp.

Greenbrier Smilax spp.

White vine Sarcostema clausum

The most common species identified for treatment include climbing cassia, Brazilian pepper, caesarweed, torpedograss, missiongrass, and Wright’s nutrush. However, all plant species listed in Table 1 and in Exhibit 3 must be eradicated.

The bid treatment area under contract must contain zero percent areal coverage of exotic/nuisance species within the label-specified or industry-standard number of days after treatment, whether calculated as a rounded whole percentage by areal coverage within a single vegetation community type (e.g., freshwater marsh or cypress forest) or within a general area (e.g., 50± acres).

Exotic and nuisance vegetation is to be removed manually or by applying herbicides.

Treatments will consist of foliar applications, cut-stump, basal bark, girdling, and/or hand removal of the entire plant. The Sub-Contractor must minimize non-target damage as much as possible. For species where the cut-stump method is used, the herbicide must be applied within 15 minutes of cutting, with the exception of Brazilian pepper, to which the herbicide must be applied within

5 minutes of cutting. Marker dye that is clearly visible shall be included with the herbicide so that treatment can be confirmed. Cuttings can be stacked in proximity to where the cutting occurred, but in a manner that preserves existing native vegetation. Treated cuttings can remain on-site. Vine species such as Old World climbing fern, greenbrier, and grapevine encountered encroaching the tree canopy shall be poodle-cut and treated in a manner that minimizes non-target damage to the surrounding native vegetation. Except for Old World climbing fern, dense mats of vines growing

-9-along the ground are not included in this scope. Hauling and disposal of cut material off-site is not required at this time.

The Sub-Contractor may suggest an alternate treatment method for any specified site work.

If an alternate method is suggested, the Sub-Contractor shall provide the methodology details to the LCPA and the GEPC for review and approval. The Sub-Contractor may not use an alternate method unless approved by the LCPA and the GEPC. The Sub-Contractor is responsible for using the appropriate treatment method for exotic/nuisance species based on industry standards, applicable local, state, and federal regulations, and label requirements.

Herbicide composition and application rates must be in accordance with current Florida

Department of Agriculture and Consumer Services (FDACS), Florida Department of

Environmental Protection, and U.S. Environmental Protection Agency (EPA) rules and regulations, along with the manufacturer’s label. All chemicals used must be labeled for use in

Aquatic Systems or Natural Areas as applicable. All herbicides must be registered by the EPA and the FDACS for use in Florida. Unregistered and/or experimental products are prohibited on this project. All chemicals must be mixed and applied by an FDACS-licensed applicator with a valid

FDACS-issued Pesticide Applicator License in Natural Areas or applied under the direct supervision of one. All chemicals used must be mixed and applied in accordance with applicable material safety data sheets and label directions. Use of soil-active herbicides containing the active ingredients imazapyr or imazapic, as well as pre-emergent herbicides, is not permitted under this project. Treatment activities should be scheduled during periods of low or no standing water, where possible, to maximize the effectiveness of the applied herbicides.

Treatment of woody/shrubby vegetation may occur at any time during the treatment window. Herbaceous vegetation shall be treated only when actively growing (i.e., non-dormant).

To maximize the effectiveness of the applied herbicides, treatment shall occur with low to no standing water or when enough of the plant is above water for adequate herbicide uptake to kill the plant. Herbaceous vegetation shall be treated only when environmental conditions (e.g., temperature, rainfall, soil moisture) and signs of active growth (e.g., green shoots, sprouting seeds) indicate that these species are actively growing and can be effectively eradicated. Ultimately, treatment must occur in accordance with the treatment schedule below (Table 2).

The Sub-Contractor is responsible for obtaining all applicable permits prior to the applying herbicides. The Sub-Contractor is to provide the LCPA copies of all labels from the actual

-10-herbicides and adjuvants utilized on this project prior to commencing any work within the designated treatment area(s). The treatment of exotic/nuisance species throughout the designated area(s) shall be subject to inspection at any time by the LCPA and/or the GEPC, and local, state, and federal agencies.

The Sub-Contractor shall be responsible for maintaining daily work logs indicating which specific area was treated, the target species and the chemicals used, quantities, and application method(s). These daily work logs shall be submitted to the LCPA and the GEPC at the end of each following work week, along with a progress map depicting the treated areas for that week in relation to the project area. The weekly progress map may be submitted in any format (e.g., JPG, PDF), but each map must be accompanied by digital data files compatible with Google Earth (e.g., KML, KMZ) and/or ArcGIS (e.g., GDB, SHP).

The storage of chemicals on-site at any time is prohibited. The Sub-Contractor will follow best management practices within any areas utilized for mixing chemicals to prevent spills and soil/water contamination. If a spill takes place, the Sub-Contractor shall be responsible for remediation. Chemical containers shall be properly disposed of off-site on a daily basis, along with any other debris generated by the work performed under this contract.

Except in the specific case of Treatment Area C (as described above in Section 4.0), native vegetation shall be protected to the greatest extent practicable. Broadcast spraying (i.e., boom spraying) is prohibited around native vegetation. However, where there is a monoculture of exotic vegetation, boom spraying may be used in conjunction with best management practices. Examples of where boom spraying may be an appropriate treatment method include open farm field areas

(e.g., Treatment Area D-1). Prior to boom spraying, the Sub-Contractor shall notify the LCPA and the GEPC and provide a map of the areas to be treated. Only after the Sub-Contractor has received approval from the LCPA and GEPC can treatment of these areas commence. Best management practices shall be utilized to avoid and minimize non-target damage and spray drift onto native vegetation. These practices include, but are not limited to, using appropriate pressure and droplet size, avoiding excessive runoff of chemical on treated plants, using appropriately labeled herbicides and adjuvants, using selective treatment methods, avoiding spraying in windy conditions, and allowing enough time for spraying prior to or after rain events. If severe, overspray or damage to non-target species may result in replanting or other remedial actions at the sole responsibility of the Sub-Contractor, if applicable.

The Sub-Contractor’s superintendent and any sub-contractors or suppliers whose presence is necessary or requested by the LCPA shall attend the pre-construction meeting. The Sub-

Contractor shall submit a detailed proposed project schedule at the pre-construction meeting. The schedule shall show a complete sequence of activities and the projected percentage of completion for each item. This schedule will be used to plan, organize, execute, and direct the work. Access to the site will be provided by the existing adjacent road network and through existing locked gates. The access gates are to remain locked at all times after entry and exit. Gate access information will be provided to the Sub-Contractor prior to starting work. The treatment areas shall be accessed through the existing on-site trail system and former farm fields and pastures. The Sub-

Contractor shall not damage existing native vegetation to establish new trails within the treatment areas. The Sub-Contractor shall be responsible for providing the LCPA information to identify who will be on-site and the type(s) of vehicles.

All equipment brought on-site for removal/treatment activities must be cleaned prior to being used at the Airport Mitigation Park to prevent cross-contamination from another site. This includes, but is not limited to, trucks, trailers, all-terrain/utility vehicles, tractors, mowers, and spray rigs. Equipment used on-site must also maintain the current state of the on-site trails. If any

-12-equipment damages the trail system or former farm fields/pastures (i.e., creates ruts), the Sub-

Contractor must restore the affected trails to their original conditions prior to ending work.

The Sub-Contractor is responsible for maintaining quality control over suppliers, manufacturers, products, services, site conditions, and workmanship to produce work of specified quality and to comply with industry standards, except when more restrictive tolerances or specified requirements indicate more rigid standards or more precise workmanship. The Sub-Contractor assumes all liability for any equipment that they store on-site during non-working hours.

The Sub-Contractor shall notify the LCPA and the GEPC of any wildlife encounters (i.e., alligator burrows and holes, bird rookeries, etc.) that may directly impact the successful treatment of the contracted work area. If such conditions are deemed limiting to the successful execution of the contracted work, alternatives will be discussed between the Sub-Contractor, the LCPA, and the GEPC, provided adequate notice is given. Wildlife avoidance and encounters will be discussed in more detail as part of the pre-construction meeting.

6.0 Treatment Schedule

The Treatment Schedule for the bid is summarized below. The NTP for work to be conducted will depend on approval of funding by the LCPA for that specific year. The LCPA reserves the right to release a portion of the work, or none of the work, during any given fiscal year depending on the availability of funds for the fiscal year. Treatment shall begin based on the LCPA

NTP and follow the schedule (Table 2) below.

Woody/shrubby vegetation may be treated any time during the treatment window.

Herbaceous vegetation should only be treated when actively growing (i.e., non-dormant) and during periods of low or no standing water to maximize the effectiveness of the applied herbicides.

Herbaceous vegetation in Treatment Area A shall be treated only when environmental conditions

(e.g., temperature, rainfall, and soil moisture) and signs of active growth (e.g., green shoots, sprouting seeds) indicate that these species are actively growing and can be effectively eradicated.

Herbaceous vegetation in Treatment Areas B and D shall be treated when seedlings and resprouts reach a minimum height of four to six inches. Treatment C shall only begin when site conditions are dry enough that mobilizing and using the mower will not cause rutting within the treatment area and surrounding wetland environments. Additional details on the timing of Treatments A, B, C, and D are outlined in Section 4.0 above.

-13-

The treatment schedule depends upon weather conditions, signs of active growth in herbaceous vegetation, and on-site water levels. The treatment schedule may be adjusted upon agreement between the Sub-Contractor and the LCPA, provided adequate notice is given before the due date. Successful completion will be determined by the LCPA and the GEPC. Provided there are no schedule delays due to weather conditions or other situations outside of the Sub-

Contractor’s control, the anticipated project schedule is as follows:

-14-

7.0 Acceptance and Payment

All areas must be verified for treatment completion by the LCPA environmental consultant

(i.e., GEPC) before the invoices can be processed on a monthly basis. No project summaries or work reports, as required by the contract documents, shall be outstanding at the time of invoicing.

All herbicide treatment shall result in mortality of all target species with minimal non-target damage. If the treated vegetation is not killed within the label-specified or industry-standard number of days after the treatment, as confirmed by the GEPC, the contractor shall be responsible for re-treating the area at no expense to the LCPA. The time frame will start from the date the contractor notifies the LCPA that the work is completed. If the contractor does not notify the LCPA of the completion date, the time frame will start when the GEPC performs the oversight inspection and confirms the area has been treated.

To be deemed substantially complete, the bid item under contract must contain zero percent areal coverage of exotic species, as defined in Section 4.0. Seedlings that grow after the treatment period (i.e., regrowth) are excluded from the areal coverage calculation. Payment will be tied to the completion of the entire area or the percentage of work completed as estimated by the GEPC.

Invoices will be approved, less five percent retainage, upon verification of treatment effectiveness, with approval of retainage upon final project completion. Any work performed under this contract shall follow the schedule in the contract (Table 2). Final acceptance of the contract efforts will be determined at the conclusion of all treatment events.

Upon completion of all treatment events, the Sub-Contractor shall request an on-site meeting with the LCPA and the GEPC for the purpose of having the work accepted. If additional work is necessary to satisfy the contract documents, a completion punch list will be prepared by the LCPA and the GEPC and issued by the LCPA. Upon completion of corrective work addressed within the punch list, the Sub-Contractor shall request a second meeting to have the work accepted.

If further work is necessary to satisfy the contract documents, the Sub-Contractor shall request a third meeting when they feel the work is complete and in conformance with the contract documents.
