1.0 GENERAL DESCRIPTION OF WORK

In January and February of 2022, Federal Highways rehabilitated the Tennessee Valley Trailhead parking lot in Golden Gate National Recreation Area to provide an all-weather, low maintenance surface that can be delineated for space-efficient parking. The project resulted in the need for revegetation work including removing non-native and invasive species and planting of live native plants that have been propagated in a local nursery. The area needing revegetation is 5500 square feet (0.13 ac). This contract will provide the delivery of native containerized plants, plant installation, mechanical removal of non-native, invasive, and/or undesired species, and maintenance watering of installed plants.

Outplanting of containerized plants is expected to occur in a time window of October 3 to November 18, 2022, based on weather condition. Non-native, invasive, and/or undesired mailto:LJ_Gravelle@nps.gov species removal by mechanical means will occur prior to installation of container plants, and again January 1-31, 2023. Maintenance watering of transplanted plants will occur two times in a window from November 1, 2022 – February 17, 2023, based on weather conditions. Due to high use of this parking lot and trailhead by visitors, all work must be conducted Monday through Friday; no work on weekends or holidays.

Figure 1. Diagram of parking lot with associated area calculations (Table 1) and number of plants by species listed below.

Planting specifications:

• Plant in weed-free prepared planting beds.

• Over-excavate each planting hole by at least 1.5 times the width of the plant and 3 inches deeper than the depth of the plant to be planted.

• Assure planting holes accommodate the full depth of the root mass, no “J-root” planting or twisting of the root mass to accommodate small holes is allowed.

• Pre-water hole to pack and moisten soil before planting plant (per the Quality

Standards below).

• Backfill holes after planting. Pack soils around plants to minimize air pockets.

• Within 6 hours or less after planting, apply water to each plant to provide moisture and to ensure no macro or micro air pockets exist in the planting hole. Watering should be done with several gallons of water per plant, spaced over several time intervals to allow water to penetrate and fill in around the newly planted plant.

• Figure 2 shows where park provided water may be obtained.

• Create a 2-inch-deep ring-shaped depression around each plant to catch water.

• All empty planting containers shall be returned to Marin Headlands Nursery.

• No additional soil can be brought into the park.

• Procure certified weed-free rice straw from a park-approved source.
