Napa Valley Vine Trail Section 4(f) De Minimis Determination

June 2020

1 INTRODUCTION The purposes of this document are to 1) identify the 4(f) resources that occur in the Napa Valley Vine Trail Project area; and 2) provide the determination that has been made under Section 4(f) of the U.S. Department of Transportation (USDOT) Act of 1966. Under Section 4(f) the California Department of Transportation (Caltrans) has determined this Project will have a de minimis impact on Section 4(f) resources. Section 6009(a) of SAFETEA-LU amended Section 4(f) legislation at 23 United States Code (USC) 138 and 49 USC 303 to simplify the processing and approval of projects that have only de minimis impacts on lands protected by Section 4(f). This amendment provides that once the USDOT determines there will be a transportation use of a Section 4(f) property, and the incorporation of avoidance, minimization, and mitigation or enhancement measures, results in a de minimis impact on that property, an analysis of avoidance alternatives is not required, and the Section 4(f) evaluation process is complete. FHWA’s final rule in Section 4(f) de minimis findings is codified in 23 Code of Federal Regulations (CFR) 774.3 and CFR 774.17.

Responsibility for compliance with Section 4(f) has been assigned to Caltrans pursuant to 23 USC 326 and 327, including de minimis impact determinations, as well as coordination with those agencies that have jurisdiction over a Section 4(f) resource that may be affected by a Project action.

2 PROJECT DESCRIPTION Two Project alternatives are being analyzed under this technical study, including the No Build Alternative and a Build Alternative.

2.1

No-Build Alternative

Under the No Build Alternative, construction of the Napa Valley Vine Trail-St. Helena to Calistoga segment would not occur. This segment is part of the greater Vine Trail, which is envisioned as a 47-mile Class I mixed-use path for pedestrians and cyclists that will run the length of the Napa Valley (Calistoga to American Canyon and connect to the Vallejo Ferry Terminal in Vallejo, California). There would be no change in existing land use or facilities and there would be no cost associated with this alternative.

2.2

Build Alternative

The Build Alternative– St. Helena to Calistoga Segment of the Napa Valley Vine Trail – would consist of two segments of bicycle and pedestrian trail for a total of 7.4 miles within St. Helena, Napa County, and Calistoga. The first segment of the Build Alternative, the St. Helena to Calistoga Segment, would be a 6.8-mile trail within Caltrans right of way (ROW), State Park lands, public property, and easements to be granted from property owners. This segment would begin in St. Helena at the intersection of Pratt Avenue and State Route (SR) 29 at postmile (PM) 29.244 and extend north where it would terminate at Dunaweal Lane east of SR 29 at PM 35.308 near the city limits of Calistoga.

The second segment, called the Fair Way Path Extension, would be comprised of a 0.6-mile bike and pedestrian trail that extends north from Washington Avenue to the intersection of Fair Way and Lincoln Avenue in Calistoga. At this location the trail would be east of SR 29 between PMs 36.45 to 37.22. The Fair Way Path Extension was previously analyzed under the California Environmental Quality Act (CEQA) and a Mitigated Negative Declaration was approved by the City of Calistoga’s Planning Commission (PC Resolution 2014-29; November 26, 2014). However, the Fair Way Path Extension was not analyzed under the National Environmental Policy Act (NEPA), and the proposed Project is subject to federal funds; thus, the Fair Way Path Extension is being analyzed under NEPA as part of this proposed Project. Caltrans is the federal lead agency under NEPA for the proposed Project including the Fair Way Path Extension.

The proposed Project is one part of the Napa Valley Vine Trail, which is envisioned as a 47-mile Class I mixed-use path for pedestrians and cyclists that will run the length of the Napa Valley (Calistoga to American Canyon) and connect to the Vallejo Ferry Terminal in Vallejo, California.

The south end of the Project would terminate in St. Helena at Pratt Avenue at the location of a future segment of the Vine Trail, and the north end would terminate at an existing segment of the Vine Trail at Dunaweal Lane in Calistoga.

Completion of the proposed Project would close a gap in the regional bicycle and pedestrian transportation network, would provide bicyclists and pedestrians with a safe alternative to using Route 29 from the City of St. Helena to Calistoga, and would encourage the use of non-motorized travel, which is described in the policies and objectives of the Napa County General Plan.

With the exception of a portion of Vine Trail through Bothe-Napa Valley State Park (BNVSP) and California Department of Forestry and Fire Protection (CalFire) property, most of the proposed Vine Trail would be on the east side of SR 29. Most of the Vine Trail would be separated from SR 29 though a few portions of the proposed Vine Trail would occur on the shoulder of SR 29. The Vine Trail would cross multiple roads and private driveways and would cross SR 29 in two locations. Pedestrian Hybrid Beacon signal crossings would be installed where the Vine Trail crosses SR 29. Safety improvements and signage would be installed at crossings to conform to applicable local and Caltrans and the California Manual on Uniform Traffic Control Devices (California MUTCD).

The proposed path would be 10 feet wide with 2-foot shoulders for a total width of 14 feet in most locations, narrowing to a lesser width (minimum 8 feet) in constrained locations or to avoid tree removals. In most locations the Vine Trail would be an asphalt trail installed over aggregate base, with gravel shoulders. Permeable asphalt may be used in some locations (e.g., along vineyard edges or aisles). In most locations, the existing surface would be excavated to a depth of 1.5 to 2 feet to install the Vine Trail surface, except within the BNVSP where the trail would partially be placed on fill, and in other areas which coincide with sensitive archaeological resources. Within the BNVSP, most of the trail would be located on existing paved roadway surface. Where the trail would be located off paved surfaces, the trail would be placed on fill to

ensure native subgrade is undisturbed. Grading would occur beyond the shoulders of the trail to conform the Vine Trail to existing grade up to a maximum slope of 2:1.

The Vine Trail would be on the road shoulder of the existing SR 29 bridges at York and Mill creeks.

SR 29 would be restriped along the approaches to these bridge crossings to accommodate the trail. Signage, striping, and barriers along the shoulder would be installed for the bike path at these bridge crossings, in accordance with local and state standards.

Retaining walls would be constructed where the Vine Trail alignment is constrained either by existing physical or topographic features, property lines, or easement boundaries. Most retaining walls would be no higher than 3.5 feet. However, in a few locations the elevation changes between the proposed Vine Trail and adjacent areas would require taller retaining walls (up to 8 feet tall). These taller retaining walls would be located within Caltrans’ ROW (at Trinchero, near the entrance to BNVSP, and at the Petit Rouge LLC property) and on private property (at Sterling Vineyards and Twomey Cellars). Excavation depths for the retaining walls would be approximately 1.5 to 3.0 feet below existing grade in areas up to 25 ft2 in size.

Free span, pre-fabricated bridges are proposed in three locations: one to span an existing wetland and drainage feature on private property near PM 31.57; one to cross an existing drainage ditch located on private property south of Twomey Winery at PM 35.282; and one to span the Napa River on Dunaweal Lane near Sterling Vineyard. Each of these bike and pedestrian bridge structures and abutments would be installed in upland areas and outside of waters and wetland features (i.e., free span).

The proposed Project would include new culverts or culvert extensions with headwalls. The type, size and material of the extended culverts would match existing conditions. Box and pipe culverts would be installed. Two existing box culverts would be extended, one at Nash Creek; one to cross an agricultural drainage ditch that discharges to Hirsch Creek; and one to extend the existing culvert crossing of Hirsch Creek at SR 29. The existing box culvert at Nash Creek would be extended by removing and replacing the existing headwall and installing up to approximately 30 linear feet of new culvert.

Underground utilities would remain in place. Utility poles in conflict with the Vine Trail would be moved in coordination with utility owners prior to construction of the Project. Other utility adjustments would include relocation of fire hydrant wharfs in a few locations. No additional or expanded use of water or wastewater facilities are proposed as part of this Project. New storm drain infrastructure manholes and junction boxes would be installed in some locations. This would be done where the trail crosses existing roads, to convey road and Vine Trail runoff away from the trail surface to culverts and adjacent drainage features. With exception of the storm drain infrastructure mentioned above, stormwater runoff from the Vine Trail would be conveyed to adjacent non-paved surfaces where it would slowly drain into the ground.

The Build Alternative is shown in Figure 1 below.

3 METHODOLOGY 3.1

Determining Section 4(f) Resources

There are two steps in determining whether Section 4(f) applies to a Project: 1. The Project must involve a resource that is protected by the provisions of Section 4(f).

2. There must be a “use” of that resource.

Protected resources include the following: • • • • 3.2

Public parks Recreational areas of national, state, or local significance Wildlife or waterfowl refuges Historic sites of national, state, or local significance 1 Definition of Section 4(f) Use

As defined in 23 CFR 774.17, a “use” of a protected resource occurs when any of the following conditions are met: • • •

Direct Use: Land is permanently incorporated into a transportation facility.

Temporary Use: There is a temporary occupancy of land that is adverse in terms of the statue’s preservation purpose as determined by the criteria in 23 CFR 774.13(d).

Constructive Use: There is a constructive use of Section 4(f) property as determined by the criteria in 23 CFR 774.15.

Section 4(f) applies to archaeological sites only if the preservation in place is warranted and sites are eligible for the National Register of Historic Places (NRHP) for reasons other than their potential to yield information (eligible for Criteria A, B, or C)

De Minimis Impacts

3.3

3.3.1 Determining De Minimis Impacts to Section 4(f) Resources A de minimis impact to a Section 4(f) resource is a nominal Project impact that would not be adverse to the activities, features, or attributes that qualify the property for protection under Section 4(f). A de minimis impact finding can be made for some direct uses and temporary uses; however, a de minimis impact finding cannot be made for constructive uses.

Under the Federal Highway Administration (FHWA) regulations (23 CFR Section 774.13(d)), temporary occupancy, including temporary construction easements, and other temporary Project activities are typically considered de minimis impacts if they satisfy specific criteria.

In the case of historic properties, a de minimis determination can only be made when there are “no historic properties affected” or the Project would have a “no adverse effect” under Section 106 of the National Historic Preservation Act (NHPA). For other Section 4(f) protected resources, including publicly owned parks, recreational areas, and wildlife and waterfowl refuges, de minimis impacts are defined as those impacts that do not adversely affect the activities, features, or attributes of the Section 4(f) resource.

The de minimis impact finding is based on the level of impact, including any avoidance, minimization, and mitigation or enhancement measures that are included in the Project to address the Section 4(f) use. A de minimis impact finding is expressly conditioned upon the implementation of measures that are relied on to reduce the impact to a de minimis level.

To reach a de minimis impact finding for properties where a use would occur, following an opportunity for public review and comment, the official(s) with jurisdiction over the Section 4(f) resource must provide written concurrence to Caltrans that the Project would not adversely affect the activities, features, or attributes that qualify the property for protection under Section 4(f).

3.3.2 Coordination and Concurrence on De Minimis Findings Coordination with officials who have jurisdiction over park and historic resources is required prior to approval of the Section 4(f) impact findings. For parks, recreational areas, and wildlife and waterfowl refuges, the officials with jurisdiction over the property must be informed of the intent to make a de minimis impact determination, after which an opportunity for public review and comment must be provided. Written concurrence from these officials is required in the following situations: • • •

Napa Valley Vine Trail Section 4(f) De Minimis Determination

June 2020

3.3.3 Public Notice to Disclose Section 4(f) De Minimis Finding After initial formal consultation is conducted with the official representing each potentially impacted resource, a meeting must be held to provide the public with an opportunity to review and comment on the Section 4(f) findings. To facilitate public disclosure, notice of the public meeting must be circulated informing agencies and the general public of the time and place of the meeting, Project description, and proposed de minimis findings. During the public meeting, the public must be afforded the opportunity to review the Section 4(f) document, as well as comment on the effects of the Project Section 4(f) resources.

After considering any comment received from the public, and whether the official concurs in writing that the Project will not adversely affect the Section 4(f) activities, features, or attributes, then Caltrans finalizes the de minimis impact determination.

3.4

Section 6(f) Resources

In addition to identifying resources protected under Section 4(f), potential impacts to properties protected or enhanced with Land and Water Conservation Fund (LWCF) grants must also be reviewed as part of this Project. Section 6(f)(3) of the LWCF Act (16 U.S.C. Section 4601-4) contains provisions to protect federal investments in park and recreational resources and the quality of those resources. State and local governments often obtain grants through the LWCF Act to acquire or make improvements to parks and recreational areas.

Section 6(f) of the LWCF Act prohibits the conversion of property acquired or developed with LWCF grants to a non-recreational purpose without approval of the U.S. Department of Interior’s National Park Service (NPS). Section 6(f) further directs DOI to assure that replacement lands of equal value, location, and usefulness are provided as conditions to such conversions.

Consequently, where conversion of Section 6(f) lands are proposed for roadway and highway projects, replacements will be necessary.

To determine whether LWCF funds were involved in the acquisition or improvement of Section 4(f) resources, database records of all LWCF-funded parks within Napa County were consulted in December 2019 to determine properties pursuant to Section 6(f). Additionally, NVTA coordinated with BNVSP to understand any historical LWCF funding. This research revealed that LWCF funds were utilized for improvements within BNVSP. Specifically, the LWCF funds were utilized for the development of yurts at the park, outside the boundaries of the Project area. Therefore, there would be no effect on LWCF-funded parks or recreational resources as a result of this Project.

4 IDENTIFICATION OF SECTION 4(F) PROPERTIES WITHIN 0.5 MILE OF PROJECT AREA Research was conducted to identify publicly owned parks, recreational areas, wildlife and waterfowl refuges, and historical sites within 0.5 mile of the Project area. There are eight Section 4(f) public park resources within 0.5 miles of the Project area, as described below. A map of the Section 4(f) resources for which the Project would pass through is shown in Figures 2 and 3.

Built Historic Resources

The Bale Grist Mill Archaeological Site is a separate Section 4(f) resource from the Bale Grist Mill State Historic Park.

The Bale Grist Mill Archaeological Site has a larger boundary than the Bale Grist Mill State Historic Park and has been listed on the NRHP because of historical archaeological resources known to occur within the Bale Grist Mill Archaeological Site.

Resources marked as “Unevaluated*” in Table 2 have not yet been evaluated for eligibility of listing on the NRHP. To be conservative, this Section 4(f) analysis assumes that these resources could be potentially eligible for listing.

4.4.1 Archaeological Resources One of the listed archaeological resources, Bale Grist Mill Archaeological Site 3, is located within 0.5 mile of the Project area and qualifies as a Section 4(f) resource because it is listed as an archaeological resource on the NRHP. Locations of archaeological resources are protected from public view to protect the integrity of the resources. As such, archaeological resources are not mapped.

4.4.2 Built Historic Resources The first listed built historical resource, the Beringer Winery Historic District, is located within 0.5 mile of the Project area and qualifies as a Section 4(f) resource.

The second listed built historical resource, the Napa Valley Railroad Calistoga Depot, located within 0.5 mile of the Project area and qualifies as a Section 4(f) resource.

The potentially eligible built historical resource, The Cavanaugh/Wright House, is located within 0.5 mile of the Project area and for the purposes of this analysis is considered to qualify as a Section 4(f) resource.

The Bale Grist Mill State Historic Park is a public park, the Bale Grist Mill Archaeological Site is an NRHP-listed archaeological site (P-28-000240). The public park has a separate and distinct boundary from the archaeological resource and are considered as two separate Section 4(f) resources. Notably, the Bale Grist Mill State Historic Park is located across SR 29 and does not directly interface with the Project area. The Bale Grist Mill Archaeological Site boundary is larger than the park’s boundary and is directly within the Project area.

5 POTENTIAL SECTION 4(F) USES 5.1

No Build Alternative

There would be no uses of park, recreational, or historic resources subject to Section 4(f) provisions with the No Build Alternative. No direct use, temporary use, or constructive use of Section 4(f) resources would be required for the No Build Alternative.

5.2

Build Alternative

The Build Alternative would result in direct effects on Section 4(f) resources. However, as discussed below and summarized in Section 6, the Build Alternative would not require temporary occupancy use, or constructive use of any Section 4(f) resource. A permanent incorporation use would occur at BNVSP. An analysis of the Project’s potential to impact and use each Section 4(f) resource within the Project area is below.

5.2.1 Bothe-Napa Valley State Park The Build Alternative would require an approximately 1.5-acre permanent easement from BNVSP. The Build Alternative includes construction of a bike and pedestrian trail and almost one mile of the Build Alternative is proposed to pass through BNVSP. Figure 3 depicts the proposed trail alignment within BNVSP, and notes where the Vine Trail would be placed on existing paved roadway, previously disturbed areas, or on undisturbed areas.

The Build Alternative would require an additional 0.7 acre of land from BNVSP for use as a temporary construction easement. However, the work would be minor in scope, typically including grading and landscaping, and there are no anticipated permanent adverse physical effects on the activities or functions of the resource due to this easement. Temporarily disturbed areas would be restored to pre-Project conditions following construction. In addition, public access to BNVSP would not be reduced as a result of construction of the Project, and any minor effects on the resource would be minimized, mitigated, and avoided.

The majority of the trail through BNVSP was sited to avoid and minimize the extent of tree removals and would be constructed on existing roads, areas that are partially disturbed, and previously undisturbed areas (See Figure 3). Where the trail would be located outside the existing roadway, the trail would be constructed on fill and excavation into native subgrade would be avoided to ensure the Project would not disturb any archaeological resources.

Moving north in the park, the trail would continue on existing paved areas up to the existing park entry kiosk. In this section there would be no ground disturbance. Work would be limited to striping and signage installation. Within the park there are cultural resources that are currently under evaluation for eligibility for listing on the NRHP (see Section 4.4.1 for a list of these resources). In the areas where the trail coincides with or within 50 feet of these historic resources, no signage would be installed in a manner which would require excavation into native subgrade and the trail would be constructed on fill to ensure no excavation beyond native subgrade would occur.

Beyond the entry kiosk to the park, the asphalt trail would be constructed between the park entrance road and SR 29. As the trail approaches the north end of the park, it would cross an existing ditch. Retaining walls would be installed along the west shoulder of the trail, south of the park entry road and within Caltrans’ ROW. In constrained areas, the trail narrows to 8 feet without shoulders but remains 14 feet where feasible.

A bus stop located just north of the park entrance would be relocated nearby prior to operation of the trail. The second, at-grade trail crossing of SR 29 would occur near the intersection of the road at the park entrance and SR 29 but would occur outside of the park boundary.

The portion of the Build Alternative that is proposed to pass through BNVSP constitutes a 0.1 percent of the total park acreage, and the existing use and access to the BNVSP would not be adversely affected. Temporary traffic controls would be implemented during Project construction consistent with applicable state standards to ensure that access to the park is not adversely affected. Neither the physical facilities, nor the functions, or activities conducted in BNVSP would be adversely affected.

Access to BNVSP is anticipated to be maintained at all times during Project construction and operation. The work would be minor in scope and there are no anticipated permanent adverse physical affects or other interferences with the activities or function of the resource. Temporarily disturbed areas would be fully restored to pre-Project conditions once temporary impacts are complete. Following completion of the trail, the BNVSP property would remain as publicly owned land by California State Parks. The Build Alternative would be a public outdoor recreational resource, which is consistent with the purpose and current uses of BNVSP. In addition, any minor effects on the resource would be minimized, mitigated, and avoided. Thus, characteristics and features that make the property eligible for Section 4(f) protection will remain.

5.2.1.1 Section 4(f) Determination The Build Alternative would result in direct effect of BNVSP. The improvements provided by the proposed Project would include a permanent easement of approximately 1.5 acres of BNVSP. No constructive use of this resource is anticipated under the Build Alternative. The BNVSP property on which the proposed trail would be constructed would remain as publicly owned land by California State Parks. The Build Alternative would be a public outdoor recreational resource, which is consistent with the purpose and current uses of BNVSP and would be a recreational benefit to the park.

According to FHWA guidance provided in the Environmental Review Toolkit for Section 4(f) Evaluations, to be considered a de minimis impact, the amount of land to be acquired from any Section 4(f) site must not exceed 10 percent of the site. Given that the Build Alternative’s direct use is below the threshold set forth in the statute, the proposed 1.5-acre easement (0.1 percent of the land) at BNVSP satisfies the criteria to be considered a de minimis impact.

Temporarily disturbed areas would be fully restored to pre-Project conditions once temporary impacts are complete. The Build Alternative would result in a direct effect of approximately 1.5

acres of BNVSP. However, the effect is minor in scope, and there are no anticipated permanent adverse physical effects or other interference with the activities or functions of the resource.

Temporarily disturbed areas would be fully restored to pre-Project conditions once temporary impacts are complete. In addition, public access to the Park would not be reduced as a result of operation of the Project, and any minor effects on the resource would be minimized, mitigated, and avoided. This easement would not adversely affect or interfere with the activities, features, or attributes of BNVSP. In summary, the Build Alternative would affect the Section 4(f) resource; however, the impact is considered de minimis for BNVSP. Therefore, no avoidance alternatives are required.

5.2.2

Tedeschi Field

The Build Alternative would include the Fair Way Path Extension. The Fair Way Path Extension would be a 0.6-mile Class I trail that extends north from an existing segment of the Napa Valley Vine Trail, from Washington Avenue in Calistoga to the intersection of Fair Way and Lincoln Avenue in Calistoga. The Fair Way Path Extension was previously evaluated under CEQA, and it was identified that the path would be located entirely within public ROW. For the purposes of this analysis, it is conservatively assumed that an approximately 0.04-acre temporary easement for the Build Alternative would be required at Tedeschi Field.

The portion of the Build Alternative adjacent to the Tedeschi Field would not affect the existing use and access to the field. Neither the physical facilities, nor the functions, or activities conducted at Tedeschi Field would be adversely affected. Access to Tedeschi Field is anticipated to be maintained at all times during Project construction and operation of the trail. There are no anticipated permanent adverse physical effects or other interferences with the activities or function of the resource. Temporarily disturbed areas would be fully restored to pre-Project conditions following construction. In addition, public access to the field would not be reduced as a result of the operation of the Project. Thus, characteristics and features that make the property eligible for Section 4(f) protection will remain.

5.2.2.1 Section 4(f) Determination The Build Alternative would not result in any direct effects on Tedeschi Field, a City of Calistoga public recreational facility. For the purposes of this analysis, it is conservatively assumed that an approximately 0.04-acre temporary easement for the Build Alternative would be required at Tedeschi Field. However, access to the field and function of the field would not be interrupted by this temporary easement, and no constructive use of this resource is anticipated under the Build Alternative.

Given that the Build Alternative’s direct effect is below the threshold set forth in the statute, the proposed 0.04-acre temporary easement (0.03 percent of the land) at the Tedeschi Field satisfies the criteria to be considered a de minimis impact.

The trail, within the Tedeschi Field boundary, occurs outside the ballpark fence line, and construction would be considered minor in scope, typically including minor grading and paving.

There are no anticipated permanent adverse physical effects on the functions of the resource.

Temporarily disturbed areas would be fully restored to pre-Project conditions once construction is complete. In addition, public access to the Field would not be reduced as a result of construction or operation of the Project, and any minor effects on the resource would be minimized, mitigated, and avoided.

In summary, the Build Alternative would affect the Section 4(f) resource; however, the impact is considered de minimis. Therefore, no avoidance alternatives are required.

Documentation of Consultation and Coordination 5.3.1 Bothe-Napa Valley State Park

Both the Napa Valley Vine Trail Coalition and Napa Valley Transportation Authority (NVTA) have met with California State Parks to discuss the need to use a small portion of BNVSP to accommodate the proposed Vine Trail: • •

•

•

•

In 2007, a meeting was held to outline a plan for a multi-use trail from Calistoga to Vallejo, which would have a preferred alignment along SR 29 and BNVSP. In February 2011, Supervising Rangers attended a Vine Trail Engineering meeting to discuss the trail alignment through BNVSP. In 2015, more meetings were held to discuss the Vine Trail alignment through the park, and staff from State Parks; Napa County Regional Parks and Open Space District; Vine Trail Coalition and Bay Area Ridge Trail were in attendance.

Also, in 2015, a meeting was held with The Nature Conservancy (at the time the current property owner of the buckeye grove), California State Parks and Napa County Regional Parks and Open Space District to discuss the portion of the trail formerly planned to exist within the buckeye grove (the trail design was subsequently revised so the trail would not go through the buckeye grove).

There has been additional coordination with California State Parks regarding potential Project impacts, Project features, and potential avoidance and minimization measures to be implemented throughout construction of the Vine Trail. The California State Parks approved the request to dedicate a portion of the Vine Trail through BNVSP as a segment of the Bay Area Ridge Trail 4 system, on April 30, 2014.

In 2016, meetings were held to discuss State Park’s concerns regarding the Vine Trail/Ridge Trail access at the Larkmead Lane entrance to BNVSP. The Napa Valley Vine Trail Coalition described the proposed designs and the proposed Project impacts, and prepared Project details for construction work that would occur within BNVSP. The Project development team described the proposed designs and potential Project impacts that would occur in BNVSP. 5.3.2 Tedeschi Field

A portion of the proposed Fair Way Path Extension would coincide with Tedeschi Field. The Fair Way Path Extension was subject to environmental review and was subject to public comment in order to comply with CEQA. The CEQA document was reviewed and approved by the City of Calistoga Planning Commission, as referenced above in the Project description.

The Bay Area Ridge Trail system is a regional plan to connect hiking, cycling, and equestrian trails on the ridgelines around the San Francisco Bay. Various trails are dedicated to the Bay Area Ridge Trail, with the goal to create contiguous trails.

Specific Measures to Minimize Harm by Specific Section 4(f) Property

During Project design and engineering, consideration was given to avoiding and minimizing impacts to Section 4(f) properties, and how to incorporate mitigation and enhancement measures into the proposed Project plans. Along with incorporating standard measures, impacts would be reduced to de minimis levels through implementation of specific measures at potentially impacted Section 4(f) resources, as discussed below.

5.4.1 Bothe-Napa Valley State Park The Napa Valley Vine Trail Coalition has incorporated avoidance and minimization measures inherent to the design of the Vine Trail. These measures include, but are not limited to the following: •

•

•

The Project would avoid excavation into native subgrade. On existing roads, no excavation would occur; work would be limited to signage and striping.

No signage would occur in areas where the trail coincides with archaeological resources.

Further, signage would not be installed within 50 feet of any known archaeological resources in a manner that would require excavation into native subgrade.

In locations where the trail is not on existing roads, the trail route was designed to minimize tree removal. Mitigation measures would be implemented to address tree removals and related requirements (e.g., protect nesting birds).

Where required to meet applicable standards (e.g. California MUTCD), safety improvements and signage would be constructed at the intersection between the trail and the entrance road to BNVSP so that the trail would not adversely impact visitor access to the park. To fulfill all requirements of the Section 4(f), California State Parks as the agency of jurisdiction, will provide written concurrence with the de minimis finding following the public comment period.

5.4.2 Tedeschi Field

The proposed Project has incorporated avoidance and minimization measures inherent to the design of the Vine Trail at this location. Some of these measures include, but are not limited to the following: •

•

The proposed Project would not occur on or within the Tedeschi ball field. The Project is proposed to occur on property owned by the City of Calistoga between the City Corps Yard to the north, and the Tedeschi ball field fence line to the south.

Where the trail coincides with the Tedeschi field boundary, the Project would require minimal excavation to install the trail. The trail would be installed at grade with existing bare and compacted dirt areas.

6 SECTION 4(F) DE MINIMIS DETERMINATION A summary of potential effects to Section 4(f) properties is provided in Table 3. Additional analysis for the resources with a potential to be impacted by the Build Alternative is included in 19

Napa Valley Vine Trail Section 4(f) De Minimis Determination

7 RESOURCES EVALUATED RELATIVE TO SECTION 4(F): NO-USE DETERMINATION Section 4(f) of the USDOT Act of 1966, codified in federal law at 49 USC 303, declares that “it is the policy of the United States Government that special effort should be made to preserve the natural beauty of the countryside and public park and recreation lands, wildlife and waterfowl refuges, and historic sites.�

This section of the document discusses parks, recreational facilities, wildlife refuges, and historic properties found within or next to the Project area that do not trigger Section 4(f) protection because: 1) they are not publicly owned, 2) they are not open to the public, 3) they are not eligible historic properties, or 4) the Project would not permanently use the property and does not hinder the preservation of the property.

7.1

Public Parks 7.1.1 Lyman Park

Lyman Park, located at 1498 Main Street, is an approximately 1-acre park owned by the City of St. Helena. Lyman Park is located 0.35 mile from the Build Alternative and the Project would not directly affect the park. There would be no indirect uses as a result of construction and operation noise, traffic, and other potential indirect impacts. Construction of the trail would entail minor excavation, grading, and paving and these impacts would be temporary and would not directly affect the Lyman Park. Construction would occur during the daytime and would not result in significant noise effects in exceedance of established standards. Similarly, temporary construction traffic would not result in any degradation of the Lyman Park facilities, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network.

20

Napa Valley Vine Trail Section 4(f) De Minimis Determination

June 2020

Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the park.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.1.2 Bale Grist Mill State Historic Park Bale Grist Mill State Historic Park, located at 3369 St. Helena Highway, is a 5-acre State Park owned by California State Parks. Bale Grist Mill State Historic Park is located approximately 50 feet from the Build Alternative, across SR 29, and would not directly interface with the Build Alternative. Thus, the Project would not directly affect the resource. In addition, there would be no indirect impacts to the resource as a result of operation of the project because the Project would not create noise or traffic impacts in exceedance of established standards. Similarly, temporary construction traffic would not result in any degradation of the Bale Grist Mill State Historic Park, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. As such, the Build Alternative would not impact the park.

The property is a Section 4(f) property, but no “use” will occur. Therefore, the provisions of Section 4(f) do not apply.

7.1.3 Napa Valley Vine Trail The existing Napa Valley Vine Trail, located on Dunaweal Lane, Calistoga, east of SR 29, is a 1mile trail segment maintained by the City of Calistoga. The Build Alternative would enhance the function of the existing trail, by creating a longer, contiguous trail.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.1.4 Logvy Park Logvy Park, located at 1745 Washington Street, is a 10.5-acre local park owned by the City of Calistoga. Logvy Park is located 0.30 mile from the Build Alternative and would not overlap with the Build Alternative. Thus, no direct uses are anticipated as part of the proposed Project.

Additionally, no indirect impacts are anticipated, including those as a result of construction and operation noise, traffic, and other potential indirect impacts. Construction of the trail would entail minor excavation, grading, and paving activities during daylight hours. Construction would be conducted during daytime hours and would not generate significant amounts of noise that would be in exceedance of established standards. Similarly, temporary construction traffic would not result in any degradation of the Logvy Park, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the park.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.1.5 Pioneer Park Pioneer Park, located at 1308 Cedar Street, is an approximately 2-acre local park owned by the City of Calistoga. Pioneer Park is located 0.20 mile from the Build Alternative and does not overlap with the Build Alternative, thus would not result in any direct uses. Additionally, no indirect uses are anticipated, including those related to construction and operation noise and traffic.

Construction of the trail would entail minor excavation, grading, and paving during daytime hours and would not result in noise effects in exceedance of established standards at the Pioneer Park.

Similarly, temporary construction traffic would not result in any degradation of the Pioneer Park, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the park.

The property is a Section 4(f) property, but no “use” will occur. Therefore, the provisions of Section 4(f) do not apply.

7.1.6 Calistoga Community Garden The Calistoga Community Garden, located at 204 Washington Street, is an approximately 1-acre garden owned by the City of Calistoga. The Calistoga Community Garden is located roughly adjacent to the Build Alternative, but does not directly interface with the Build Alternative, thus would not result in any potential direct uses of the garden. In addition, there would be no indirect uses as a result of construction and operation noise, traffic, and other potential indirect impacts.

Construction of the trail would entail minor excavation, grading, and paving activities during daytime hours and would not result in significant noise effects in exceedance of established standards. Similarly, temporary construction traffic would not result in any degradation of the Calistoga Community Garden, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the park.

The property is a Section 4(f) property, but no “use” will occur. Therefore, the provisions of Section 4(f) do not apply.

7.2

Historic Sites of National, State, or Local Significance 7.2.1 The Beringer Winery Historic District

The Beringer Winery Historic District is located at the north end of St. Helena in Napa County, along the west side of SR 29. The character defining features of the historic district include the architecture and design of individual contributors, along with circulation routes and significant landscape elements. The historic district is easily identified by an alley of elm trees lining SR 29, the St. Helena Historic Elm Tunnel, which is a distinct boundary marker for the Beringer property.

The Build Alternative would be located approximately 20 feet east of the St. Helena Historic Elm Tunnel and would not result in any direct or indirect uses of the site.

22

Napa Valley Vine Trail Section 4(f) De Minimis Determination

June 2020

The majority of the trail adjacent to the St. Helena Historic Tunnel would not include any tree removals and would be constructed in the location of an existing pedestrian path, which would be removed and replaced as part of the Project. Further, the proposed Project would be constructed outside of the dripline of the trees that comprise the Elm Tunnel. Interlocking pavers installed in the 1980’s immediately east of the Elm Tunnel would be removed and replaced with permeable pavement or similar design to meet ADA requirements. The existing path is constructed on an easement granted to the City of St. Helena by Beringer Winery for the purposes of a recreational path. The proposed Project would be installed within the limits and in accordance with the existing easement.

The portion of the Build Alternative that is adjacent to the St. Helena Historic Elm Tunnel would not affect the existing uses and access to the tunnel. Neither the physical facilities, nor the functions, or activities conducted in the St. Helena Historic Elm Tunnel would be adversely affected. Access to the St. Helena Historic Elm Tunnel is anticipated to be maintained at all times during the Project’s construction and operation. The work would be minor in scope and there are no anticipated permanent adverse physical affects or other interferences with the activities or function of the resource. Temporarily disturbed areas would be fully restored to pre-Project conditions after construction. In addition, public access to the Elm Tunnel would not be reduced as a result of the operation of the new bike path. The Build Alternative would not impact the listed historical resource.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.2.2 Napa Valley Railroad Calistoga Depot The Napa Valley Railroad Calistoga Depot, located at 1458 Lincoln Avenue, was declared a historical landmark in 1959 and was listed on the NRHP in 1976. The Napa Valley Railroad Calistoga Depot is located approximately 50 feet from the Build Alternative and would not directly interface with the Build Alternative. Thus, the proposed Project would not result in any direct uses. In addition, there would be no indirect uses as a result of construction activities, including via noise and traffic. Construction of the trail would entail minor excavation, grading, and paving activities during the daytime and would not result in noise effects in exceedance of established standards. Similarly, temporary construction traffic would not result in any degradation of the Napa Valley Railroad Calistoga Depot, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the listed historic resource.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.2.3 The Cavanaugh/Wright House The Cavanaugh/Wright House, located at 3107 St. Helena Highway, is a one-and-a-half story residence and is an example of bungalow architecture from the early twentieth century. The Cavanaugh/Wright House is located approximately 100 feet from the Build Alternative and would not directly interface with the Build Alternative, thus would not result in any potential direct uses.

In addition, there would be no indirect uses as a result of construction and operation noise, traffic, and other potential indirect impacts. Temporary construction of the trail would entail minor excavation, grading, and paving activities during the allowed construction times and would not result in significant noise effects. Similarly, temporary construction traffic would not result in any degradation of the Cavanaugh/Wright House, or disruption of functions, as a result of construction vehicles temporarily utilizing the local roadway network. Operation of the trail would not create noise or traffic impacts that would affect the function of the resource. The Build Alternative would not impact the eligible historic resource.

The property is a Section 4(f) property, but no “use” will occur. Therefore, the provisions of Section 4(f) do not apply.

7.2.4 Bale Grist Mill Archaeological Site Bale Grist Mill Archaeological Site, located at 3369 St. Helena Highway, is an NRHP-Listed Archaeological Site. The Bale Grist Mill Archaeological Site is located within the Build Alternative boundaries, however the proposed Project would not result in any potentially direct uses. Where the proposed trail coincides with the known limits of the archaeological resource associated with Bale Grist Mill Archaeological Site, the trail would be constructed on SR 29 or on fill and would not require any excavation into native subgrade. Thus, the Build Alternative would not impact the listed archaeological resource.

The property is a Section 4(f) property, but no “use” would occur. Therefore, the provisions of Section 4(f) do not apply.

7.2.5 Archaeological Sites within Bothe-Napa Valley State Park Within the Project APE, several archaeological sites are located in BNVSP, as detailed in Table 2.

Within BNVSP, the trail would either be constructed on existing paved roadway or on fill, to ensure native subgrade soils remain undisturbed. Further, within BNVSP, any signage would be sited at least 50 feet away from known archaeological resources and placed on fill. Given that no native subgrade would be disturbed, the Project would not have direct or indirect effects on the archaeological sites within BNVSP. These archaeological sites are considered Section 4(f) properties, but no “use” would occur.

Therefore, the provisions of Section 4(f) do not apply.

7.2.6 Remaining Archaeological Sites Remaining archaeological sites within the APE consist of resources identified in Table 2 that are not discussed in Sections 7.2.1 through 7.2.5. Specifically, resources included in this section 24

Napa Valley Vine Trail Section 4(f) De Minimis Determination

June 2020

include unevaluated resources and potentially eligible resources. None of the remaining archaeological resources included in this section were previously listed on the NRHP. Where the trail coincides with the known limits of archaeological resources, the trail would be constructed on fill and would not require any excavation into native subgrade within the limits of those resources. Given that no native subgrade would be disturbed, the Project would not result in any direct or indirect effects on known archaeological sites.

These archaeological sites are considered Section 4(f) properties, but no “use� would occur.

Therefore, the provisions of Section 4(f) do not apply.

8 CONCLUSION In summary, although the proposed Project would require the direct use of BNVSP and Tedeschi Field, both of which are Section 4(f) properties, the effects are considered minimal. Based on the review presented in this document, the proposed Project would not adversely affect any of the activities, features, or attributes that qualify BNVSP and Tedeschi Field as Section 4(f) resources, and the direct use is therefore determined to be de minimis.
