Address of Work Location (Figure 1)

Magee Marsh Visitor Center (Ottawa County)

13229 West State Route 2

Oak Harbor, OH 43449

Scope of Work:

1. Site Preparation and Clearing:

o Current shrubs (viburnums and hydrangeas) have recently been cut back to approximately 2’ above ground, but have begun to fill out. Contractor will need to shape shrubs to facilitate placing geo-textile fabric and rock. Special care shall be taken to not damage the roots or plants.

o Contractor will need to install edging or create a ledge to prevent rock from sliding off the fabric where landscaping is sloped.

o Contractor will need to remove mulch/topsoil and obstructions along the proposed walking pathways, river stone features, and four garden areas.

o Excavate and prepare the walkway to ensure proper drainage.

o All cleared vegetation, topsoil, and debris will need to be disposed of offsite.

o Geo-textile fabric will be placed under all areas that call for rock or stone.

2. Gravel Walkway Installation (Figure 2):

o The walkway will consist of a 4’ wide path composed of 6-inches of compacted limestone gravel creating a winding path along the pond and visitor center.

o Removal of approximately four inches of topsoil along the path. Compact subgrade and walkway base layer a full width until no visible evidence of further consolidation.

o Place geo-textile fabric across the entire landscaped area prior to any stone being placed.

o Install gravel, ensuring a level and secure pathway.

2. Hardscape Installation (Figure 3):

o River Stone will be composed of 2–6-inch washed river stone and similar to existing stone placed around the north side of the visitor center. Five fieldstone boulders will be incorporated into river stone borders around garden beds in zones A and B (provided by the contractor).

o Excavate & remove the topsoil and prepare the ground for installation. Create or install edge to prevent river stone from falling down the slope.

o The contractor is responsible for placing the geo-textile fabric across the entire rocked area prior to any stone being placed, including pond edges. The fabric is to be placed in a manner that is continuous with no breaks or tears.

o Riverstone shall be thick enough to cover geo-textile fabric.

o Arrange river stones aesthetically, incorporating them into the landscape design as decorative elements.

o Hardscape landscaped Zones (Figure 3) o Zone A – Includes area south of visitor center between entrance bridge and back parking lot. This area will include the walkway and three pollinator gardens.

o Zone B – Includes approximately 275-foot western edge of pond starting at the back parking lot and ending at the main parking lot.

o Zone D - Includes the 155-foot eastern edge of the pond following the visitor center walkway.

o Zone E – Includes the 220-foot northern edge of the edge of the pond between the entrance bridge and the back parking lot.

o Arrange river stones in a uniform manner around shrubs, building and walkway.

o Riverstone around the pond (zones B, D, and E) will be from the sidewalk or blacktop to approximately 1’ past the shrubs.

o Riverstone in Zone A will be placed according to drawing and tapered to edge of pond.

3. Softscape Installation:

o Zone A will be planted in accordance with attached PDF drawing using the plants on the plant list.

o Prepare the soil for planting by amending it with organic matter to enhance fertility and drainage.

o Zone A - All beds will be covered with high-quality landscape fabric in the prepared areas. This fabric needs to prevent weeds from growing through the mulch while allowing water to drain. Mulch will only be used in the three pollinator gardens and the grass edging along deck.

o Zone C will consist of preparing the soil to seed a mixture of coreopsis, beebalm, aster, milkweed, and butterfly weed. This area to be re-sloped and soil added to create an even slope for planting. Approximately 9’ of sod will remain from the blacktop to planting to create a clean mowed edge along the parking lot.

o In Zones B, D, and E between the river stone and pond soil will be prepared to seed to a mixture of prairie dropseed, purple coneflower, and black-eyed Susan.

4. Safety and Accessibility:

o Ensure that all pathways are ADA-compliant and accessible to visitors of all abilities.

o Implement safety measures during the construction phase to protect both workers and visitors.

o Adherence to all environmental regulations and best practices during construction to minimize disturbance to the surrounding ecosystem.

o Implementation of sediment and erosion control measures to prevent runoff into water bodies.

5. Quality Assurance:

o Regular quality checks during construction to ensure that specifications and engineering standards are met.

Project Timeline: The construction is scheduled to commence with approval of the project purchase order and is anticipated to be completed by April 15, 2026. Seeding will take place between September

15 and October 31 or March 15 and April 15. Potted plants will need to be planted between September

1 and October 15 or March 15 – April 15.
