SCOPE OF SERVICES FOR

PARKING LOT IMPROVEMENTS AND BACKCOUNTRY TRAIL BRIDGE Installation

A. PROJECT OVERVIEW

1. Greenbrier State Park is managed by the Maryland Department of Natural Resources

(DNR), Maryland Park Service (MPS)

2. Greenbrier State Park Address: 21843 National Pike. Boonsboro, MD 21713.

3. Project Site Address: 21338 Greenbrier Road Boonsboro, MD 21713.

4. DNR's Mission:

As part of the Department of Natural Resources, the Maryland Park Service (MPS) manages the natural, cultural, historical, and recreational resources on State lands to provide the best use for the benefit of people.

The primary mission of the MPS system is to manage the natural, cultural, historical, and recreational resources to provide for wise stewardship and enjoyment by people.

5. Facility Background:

Greenbrier State Park was established in 1963 along the spine of South Mountain and adjacent to the historic National Road. Over the next 15 years the park’s core amenities, including a dam/lake, campground, and day-use area, were developed and improved. A highlight of Greenbrier is the Appalachian National Trail, which traverses the park.

Today, Greenbrier is one of Maryland’s most popular state parks, often filling to capacity on weekends.

Natural Resources: Greenbrier State Park is a 1,408 acre natural area managed by the Maryland Park Service. It anchors the larger South Mountain Recreation Area – DNR lands along the ridge of South Mountain over the breadth of the state.

Built Environment: 42-acre man-made lake with 1,000 feet of beach, Visitors Center with historical displays, four reservable gazebo shelters, 164 camp sites and supporting facilities (e.g. bathhouses, etc.) park-wide trail system with connection to the Appalachian Trail.

Current Uses: camping, swimming, picnicking, fishing, hunting, trail-related recreation, nature viewing.

B. PROJECT PURPOSE

This program is to request design consulting services for Greenbrier Road Parking Lot Improvements and Backcountry Trail Bridge over Little Beaver Creek.

C. PROJECT JUSTIFICATION

As Greenbrier primary day-use parking serving the lake has come to fill-to-capacity on weekends, the park’s outlying access points serving the trail system have gained outsized importance for park visitors focused on the area’s backcountry amenities. One of these spots, known as the “Northern Trailhead Lot” is located along Greenbrier Road and connects to the Big Red Trail.

Little Beaver Creek is the primary waterway passing through the park. Growing quickly to sixteen feet in width, it creates a barrier to many park visitors, intimidated by scrambling over slippery unstable rocks and not willing to risk wet feet. This project will improve access from the county roadway by paving the parking area and improving sightlines.

D. PROJECT DESCRIPTION

Scope of Work (SOW) consists of two distinct adjacent elements: 1) Improvements to the existing parking area along Greenbrier Road, and 2) A new trail bridge over Little Beaver Creek, along the connecting spur linking the parking area to the Big Red Trail. As the parking area will serve as staging area and construction access for the bridge project, project sequencing, including stormwater and erosion control features, must be coordinated to achieve maximum value and efficiencies.

A summary of suggested bridge and parking characteristics is provided below. The design tasks to be performed by the consultant are as described under the subsequent scope of work.

1. Backcountry Trail Bridge: The project develops a trail bridge to replace the current ford crossing of Little Beaver Creek. Required bridge length is estimated as 30-feet.

Intended use of new bridge is muscle-powered trail users (walkers/runners, bicycles, horses) Bridge width (clear) shall be 72-inches.

If the bridge deck is greater-than 48” inches, railings are required. Otherwise a curb may be used. If railings are required, their height shall be 54-inches and appropriate for equestrians.

Final bridge location is TBD as part of the design process. Crossing is along an existing trail and DNR’s preference is for the bridge site to be the existing ford. However, if as part of the design process, the A/E determines a different location is superior, DNR will consider alternatives – location options will be presented as part of the Schematic Development submittal.

Regarding form of bridge. Assuming a study of hydrological and other factors confirm a

30-foot span is appropriate, DNR has an existing 30’x6’ timber trail bridge design utilizing engineered beams (PWT Treated LVL or Parallam Plus PSL). Preferred option is for the A/E to develop appropriate abutments at the site to use this span design.

2. Parking Lot Improvement: The existing lot at 21338 Greenbrier Road is a single entrance to one side leading to an unmarked rectangular graveled area accommodating parking on either side separated by a single informal aisle. Project goals include formalizing the lot and entrance and installing a paved surface appropriate for light-duty vehicles.

Parking footprint is currently approximately 90’x45’. Goal for the improvement is to keep the center-aisle configuration with a minimum of 18 and up to 24 10-foot-wide spots. Spaces are for single-vehicles only – no trailer spots are required. The southeast corner of the lot provides trail access, and the update should preserve such an entrance without requiring visitors to thread between parked vehicles to enter the park. The improvements should include wooden traffic barrier to create a division between the parking and roadway.

Regarding ADA access. Lot should include a single ADA spot closest to the trail access point.

Regarding existing conditions. While the current lot is graveled, DNR cannot speak to the depth of the improvement or type of materials. There are similar comments on the entrance – it is existing, but DNR makes no statement as to formal filings with Washington County Public Works for access to Greenbrier Road.

3. Construction Access: Construction access for the project should occur through the existing entrance from Greenbrier Road and along the existing trail spur. The existing gravel lot will provide any required staging of materials for the bridge project.

4. Stormwater Management: The consultant will be responsible for the full SWM design and MDE approval. Specifically for parking elements, while the current lot is graveled, there are no existing stormwater diversions or retention features.

5. Permitting: The A/E shall be responsible for preparing and submitting all necessary documents to secure all applicable permits for this project, MDE Stormwater Management / Sediment Erosion Control, MDE Wetlands and Waterways (as applicable), and any other required permits from Federal, State, and local regulatory agencies. At the proposed bridge site, Little Beaver Creek has an MDE Designated Use Class of III-P.

6. Forest Conservation: The project should not involve the loss of any forested area. To the extent that individual trees might be lost due to the project, the A/E shall solicit comments from the DNR Forestry Division on replacement. All comments shall be addressed and incorporated in the final design drawings. A Forest Conservation Plan shall be included if the project exceeds 40,000 SF of forest disturbance.

7. A/E Services: A/E services will be required to assess, design, and oversee the construction of this project. This work is included as part of this project request.

E. PERMITS AND CODES:

The A/E shall be responsible for securing all permits associated with the proposed work.

Coordination with the Maryland Department of the Environment and the US Army Corps of Engineers will be the responsibility of the A/E. In addition, the design shall comply with US and Maryland Department of Occupational Safety and Health Administration Standards (OSHA & MOSHA), IBC, NFP, NEC, NPC, State and Local Health Department Regulations, and any other applicable codes.

F. SURVEY AND GEOTECHNICAL REQUIREMENTS:

Any site survey work required to complete the design of this project shall be the responsibility of the A/E. The A/E shall be responsible for any boring and geotechnical analysis necessary for the design of the bridge abutments, construction of the bridge, and the parking lot improvements.

The A/E shall be responsible for providing As-Built documentation upon completion of the project.

G. BID DOCUMENTS:

The A/E consultant for this project shall prepare detailed plans, specifications, and cost estimates through the bid document phase and provide professional engineering consulting services during the construction phase of the project as described in the Department of General Services (DGS) “Procedure Manual for Professional Services,” and in the Standard Form of Agreement with Architects and Engineers, (DGS Form 2), latest edition.

H. DESIGN SCHEDULE:

The A/E shall submit their proposed work schedule to DGS and DNR for approval. The A/E shall make document submissions at the schematic, design development, and construction phases for review. The construction phase submissions (50%, 95% and 100% minimum) shall include construction documents, specifications and cost estimates per the DGS Procedure Manual.

I. HARD COPY AND DIGITAL FORMAT SUBMITTAL:

During the design submittals (schematic – 95%) digital documents are desired. However, DNR requires that one (1) half-size set of the drawings accompany each submittal. Upon generating the 100% bid documents hard copy sets shall be provided to DNR for project management during construction:

Three (3) bound copies of each of the following will be required:

• Full scale drawing set (24”x36”)

• ½ scale drawing set (12” x 18”)

• Specifications

In addition to the submittal requirements previously stipulated, 100% Inspection Reports and documents shall be submitted to DNR upon completion in digital pdf and AutoCAD (DWG) data format for archiving and future use by DNR.

J. MISCELLANEOUS REQUIREMENTS

The A/E shall coordinate with the Maryland Park Service management and staff for all data gathering and site inspection within the property. Timely notice must be given to the Park staff so that they are available to meet. At all times DGS and DNR – Engineering & Construction staff must be notified prior to any changes to the A/E’s site visit plans and process. MDE must also be notified for coordination with site visits.
