30 Existing Conditions Grocery stores should also be considered in key destinations 33 Existing Conditions Spring Street going west beyond City limit on to White Sulphur Springs needs to be evaluated and included. 34 Existing Conditions Crossing Assessment should include need for and recently passed state law regarding daylighting. 36 Existing Conditions Key for Bicycle LTS labels roads as “arterial & collector” instead of Low or High LTS 38 Existing Conditions When space gets constrained, the first solution tends to be to downgrade the bike facilities to shared-road facilities, even if that is not the lowest-stress or what is planned for the street – see Oak Avenue Vine Trail alignment, Spring Street discussions, and the Class III portions of South Crane and Grayson for examples. How can the City be better equipped to shift space away from vehicles and to appropriate bicycle facilities when the need calls for it? 38 Existing Conditions Connectivity Needs Assessment should include gaps in bicycle network in its key challenges 39 Existing Conditions Shared micromobility services should be integrated with accompanying education to avoid increasing unsafe road user behavior.
Should also follow infrastructure improvements so that there are safe and comfortable facilities for these users to use to avoid unintentionally increasing road user conflicts (for example, e-scooters on sidewalks because road does not feel safe) 43 Network-wide
Recommendations
Madrona from Hudson to Riesling is narrow. Suggest class III instead of bike lanes (class II) 43 Network-wide
Recommendations
Include application of bike lane buffers and rumble strips on Silverado Trail for any Silverado Trail segment that falls under City jurisdiction where this is feasible
43 Network-wide
Recommendations
Update College Ave to proposed Class I by widening existing sidewalk – the Montessori School has expressed interest in better, more separated bike facilities from Pope to the school and many kids & parents are not going to feel safe/comfortable bike on a Class III to the Montessori during drop-off period
43 Network-wide
Recommendations
Are Class IIs realistic on Allyn & Hudson? With residences, unlikely that parking will be removable to make space. Might be better to make a Class III bike boulevard with traffic-calming. These are neighborhood streets that should be slowed down, especially as both motorists use them as cut-throughs and bicyclists use them to get to quieter side street routes. 43 Network-wide
Recommendations
Elmhurst – Consider a Class II/Class III combo given steep incline, which could benefit from a separated space for bicyclists, especially given connection to Vine Trail
43 Network-wide
Recommendations
Pratt Avenue along the Vine Trail alignment should be Class I, not Class II. 44 Network-wide
Recommendations
Show proposed Class I path on Spring Street on the map and in the list of projects. Do not remove existing Class II bike lanes on Spring Street. If there are verified issues coming up around those bike lanes, try to adjust and problem solve before just removing bike lanes. 44 Network-wide
Recommendations
Entire Pope Street corridor needs improvement, but it is only listed for a Class I from Starr to Silverado Trail and no other upgrades. This plan mentions earlier that bike facilities would be upgraded to Class I for entire corridor, but it isn’t shown in proposed bike facilities.
Also, existing facilities map shows Class II bike lanes where there are Class IIIs. 45 Network-wide
Recommendations
General comment on ADA requirements at crosswalks. The yellow raised bumps are very irritating to those in wheel chairs. There needs to be a smoother alternative to this while keeping it's purpose intact, presumably to help blind folks. 45 Network-wide

#11 crossing at main/1000 main. Why needed. Close to Charter oak crossing 47 Network-wide
Recommendations
Crossing improvements needed at Main & Grayson with Mills realignment, given upcoming Farmstead hotel project and Our Town St Helena affordable housing project going in. Crosswalks needed on all four legs of intersection, as well as sidewalk connection to intersection on south side of realigned Mills (on north end of affordable housing project). 47 Network-wide
Recommendations
I live on Chiles Ave. and the situation the potential for a severe crash is huge when trying to turn left from Chiles Avenue onto Pope Street if there cars parked on Pope Street anywhere near the intersection. I couldn't find any reference to extending the red curbs along this stretch of road adjacent to the intersection even with the 20 feet of it as per the new law. But, quite frankly, 20 feet is not enough given the situation and likelihood of being struck by a car when trying to inch one's way safely from Chiles Avenue onto Pope Street. 48 Network-wide

Recommendations
Adams & Oak should not be listed as not needing any improvements. We hear a lot of concern about this intersection given how heavily travelled it is and its vicinity to elementary school & downtown. Will also be a key intersection in Vine Trail alignment. Frequently hear and see people not stopping at stop signs. Should receive treatment like curb extensions or a raised intersection. 49 Network-wide

Adams and Kearney – need to improve sightlines at crosswalks across Adams. Right now cars can park in loading zone or curbside too close to crosswalks especially in an elementary school zone. Need to add red curb or bulb-out. 49 Network-wide
Recommendations
Fill bicycle facilities gap between where Class IIs are shown to end on Madrona and Vine Trail access on Fulton 50 Network-wide
Recommendations
More bike traffic should be expected and accommodated crossing Silverado Trail at Pope with Howell Mountain Road segment being converted to bike/ped trail. Especially with plans discussed in Appendix to realign Pope Street to be a single intersection with Silverado Trail and Howell Mountain Road. The trail will not be adding parking so bicyclists will be directly accessing. 57 Implementation Surprised at how low Main at Pratt is on prioritization – maybe this should be re-evaluated given NVTA Michelin Mobility Intelligence Road Safety Risk Report (2025) results, which identify this area as high-risk for vulnerable road users and motorists due to high traffic volumes, unsignalized crossings, and aggressive driving behaviors. They recorded frequent high-speed and severe braking events in this area.
58 Implementation Address how roadway extension projects impact City General Plan goals around reducing VMT. 59 Implementation Why are cost ranges only shown for bicycle facilities and not for other proposed projects in this plan? Show all cost ranges to provide complete context of what potential costs of projects.
59 Implementation Cost ranges for bike facilities way too high, particularly for Class I and Class II. There may be some exceptional projects that are higher than the average cost, but the lower end of the cost range should definitely be lower. 68 Transitioning from a sidepath to slightly wider sidewalks closer to downtown will need to include a transition plan for bicyclists.
Otherwise, bicyclists will continue on the sidewalk because it’s more comfortable and separated and they may not know that it has shifted to a sidewalk rather than a sidepath.
69 Valley View to Hudson – narrow travel lanes to 10.5’ and give that extra foot to the shared-use path. As much space as possible on the sidepath is necessary for safe and comfortable sharing between pedestrians, kids on bikes, and less confident bicyclists. 69 Spring St shared-use sidepath is going to need to be identifed as usable by bicyclists and pedestrians, given the unconventional street design of the corridor with the sidepath and two sidewalks 70 We support the Kearney/Spring intersection improvements – will help calm Spring St traffic and improve pedestrian visibility and safety, as well as removing a parking space that shouldn’t be used due to its visibility obstruction. 70 I live on Spring Street at the Kearny intersection. I disagree with the need to add another crosswalk to the one already existing. I also disagree with the curb extension. That would eliminate a parking spot. Parking is already a 71 The Adams St extension will place a new roadway on top of the city owned and operated levee. So, my questions are 1) If the Adams Extension Project costs $60 million, and the levee fails, who will pay for the road to be replaced? And, who will be liable for the cost of the actual levee failure, levee replacement and property damage to the Hunter proposed project homes, Vineyard Valley and Hunt's Grove. (Presently, the City of St Helena took ALL financial liability for the levee in CA State Assembly Bill 1898). Question 2: The funding St Helena recieved to construct the levee required the City to not use any part of the project for municipal purposes, bc the the funding was granted on the basis of Flood Control Use only. How is the City going to get approval for using part of the levee for municipal purposes? Question 3: What is the process to get the private property owner on the east side of the river to grant right of way for the bridge and how much will that cost the City to purchase it or pay for eminent domain? 77 Plan should make it very clear that the diagrams of the proposed Oak Ave extension project are outdated and should not be used as guidance – 4-foot bike lanes on a street with 12’ travel lanes would NOT be considered best practice today. Strongly oppose suggestions from previous, outdated plans that recommend a 40-mph speed limit; this extension should match the character of the existing Oak Avenue and neighborhoods around it. Plan should also recommend option of making extension a Class I shared-use path only if full road extension is not feasible.

Project: St. Helena Streets Master Plan
Re: Project Prioritization Methodology
All recommendations in the Streets Master Plan will take time and resources to implement. Recognizing funding and capacity constraints, as well as feasibility challenges, recommended infrastructure projects will be prioritized through a data-driven process, informed by public input. Bicycle facility, pedestrian crossing, bridge realignment, and road extension projects will be prioritized based on the criteria summarized in the table below and explained further on the following pages. Each project will receive points based on each criterion, with total points determining their relative ranking. Bicycle/pedestrian projects rely on different criteria than road/bridge projects.
The results of prioritization will help the project team develop an implementation plan and timeline with high, medium, and low priority projects. This process will also enable the team to strategically select a handful of highimpact initiatives to advance into conceptual design. By identifying top-priority projects, the team can focus on those with the greatest potential to benefit the community and achieve key project goals. This approach ensures that resources are allocated efficiently, concentrating efforts on projects that deliver the most meaningful impact and establishing a clear foundation for phased, effective progress.

2 Bicycle and Pedestrian Project Prioritization Criteria The following methodology was developed for ranking bicycle facility and crossing improvement projects.
Access
This criterion scores projects based on how well they improve access to schools, parks, and community facilities.
Score
(Points)
Metric
High (2) Project is directly adjacent to a school, major park, or community center Medium (1) Project is located within walking distance (0.25 mi) of a school, major park, or community center Low (0) Project is not located within walking distance (0.25 mi) of school, major park, or community center Safety
Projects located near recent crash sites (per 2019-2024 crash data) may address key safety issues in St. Helena.
Score
(Points)
Metric
High (2)
Project located within 100’ of the site of:
• One fatal or severe bicycle or pedestrian crash; or
• Two or more bicycle or pedestrian crashes, regardless of severity Medium (1) Project located within 100’ of the site of one non-fatal/severe bicycle or pedestrian crash Low (0) No crashes occurred within 100’ of project site Connectivity
This criterion evaluates whether a project fills a gap in the network (and thus improves bicycle/pedestrian connectivity) or improves the quality of an existing bikeway or crossing. Projects that fill critical gaps in the network receive slightly more points than those that enhance existing infrastructure.
Score
(Points)
Metric
High (2) Project fills a gap in bicycle or pedestrian network (i.e. new bikeway where it does not currently exist or
Medium (1) Project enhances existing infrastructure
Community Support
Projects that address locations identified by community members as top priorities through public engagement receive two points, projects that received some support receive one point, and projects that received no community support receive 0 points. Project support will be quantified based on feedback received on the engagement boards presented to the St. Helena community during October 2024 engagement events.
3 Score
(Points)
Metric
High (2) Project scored among top-priority projects
Medium (1) Project received some support, but didn’t rank among top priorities Low (0) Project received no support
Bonus Point: Activity
Bicyclist and pedestrian count data was collected at select locations throughout the city as part of this planning process. Projects within 100’ of a location with high relative pedestrian/bicyclist counts receive one bonus point as this demonstrates an area where improvements may benefit the most people. This criterion is only worth one point as it is limited only to the places where count data was collected.
Score
(Points)
Metric
Yes (1) Project within 100’ of location with relatively high bicyclist/pedestrian counts No (0) Project not within 100’ of location with relatively high bicyclist/pedestrian counts
4 Roadway Extension and Bridge Realignment Project Prioritization Criteria The following methodology was developed for ranking road extension and bridge realignment projects.
Feasibility
Some of the road extension and bridge projects may require acquisition of privately owned land and therefore may not be realistic options for implementation. Projects that do not require the acquisition of private land receive 1 point.
It should be noted that ultimately all road/bridge projects will involve complexity and will have varying constraints, such as need for an EIR.
Community Support
Projects that address locations identified by community members as top priorities through public engagement receive two points, projects that received some support receive one point, and projects that received no community support receive 0 points. Project support will be quantified based on feedback received on the engagement boards presented to the St. Helena community during October 2024 engagement events.

PER MILE COSTS BY
BICYCLE FACILITY CLASSIFICATION
The following pages provide backup documentation for the calculation of per-mile costs by bicycle facility type. These unit costs were used to develop planning-level estimates for each discrete proposed bicycle facility. For every recommended segment, the appropriate facility type, and corresponding low- or high-cost treatment, was assigned and then multiplied by the relevant per-mile cost to generate a segment-level estimate.

The unit costs and soft costs/contingencies applied to all cost estimates can be found on this sheet. Unit costs are presented in Table 1, and soft costs/contingencies are in Table 2. These values can be updated, as needed.
Opinions of probable cost were developed by identifying major pay items and establishing rough quantities to determine a rough order of magnitude cost. Contingencies are included to cover items that are undefined or are typically unknown early in the planning phase of a project. Unit costs are based on 2024 dollars and were assigned based on historical cost data from the Caltrans Contract Cost Data. Cost opinions do not include easement and right-of-way acquisition; permitting; surveying, geotechnical investigation, environmental documentation, special site remediation, escalation, or the cost for ongoing maintenance. A general cost has been assigned to certain general categories such as utility relocations; however, these costs can vary widely depending on the exact details and nature of the work. The overall cost opinions are intended to be general and used only for planning purposes. TDG Engineering, Inc. makes no guarantees or warranties regarding the cost estimate herein. Construction costs will vary based on the ultimate project scope, actual site conditions and constraints, schedule, and economic conditions at the time of construction.
Soft Costs and Contingencies
As applicable, contingencies for construction, environmental impacts, drainage, utilities, and design are assumed. Contingencies that vary facility type to facility type are based upon our experience with the complexities of implementing them.

Additional pay items have been assigned approximate lump sum prices based on a percentage of the anticipated construction cost. Planning-level cost opinions include a 35% contingency to cover items that are undefined or are typically unknown early in the planning phase of a project. Unit costs are based on 2025 dollars and were assigned based on historical cost data from Caltrans Contract District 4 Cost Data.
Cost opinions do not include easement and right-of-way acquisition; permitting, inspection, or construction management; engineering, surveying, geotechnical investigation, environmental documentation, special site remediation, escalation, or the cost for ongoing maintenance. A cost range has been assigned to certain general categories such as utility relocations; however, these costs can vary widely depending on the exact details and nature of the work. The overall cost opinions are intended to be general and used only for planning purposes. Toole Design Group, LLC makes no guarantees or warranties regarding the cost estimate herein. Construction costs will vary based on the ultimate project scope, actual site conditions and constraints, schedule, and economic conditions at the time of construction.

Subject: St. Helena Streets Master Plan – Adams Street Extension Levee Impact Review This memorandum provides an overview of the proposed Adams Street roadway extension from the existing levee to Silverado Trail N. A proposed bridge and road through the flood plain are required for this roadway extension. Below is BKF’s review including a street design summary, stormwater management, and geotechnical considerations.
OVERVIEW
The Adams Street extension is planned to extend from Starr Avenue to Silverado Trail N including a bridge across Napa River. The roadway coincides with a levee for about 1000 feet, before diverging to cross a Habitat Restoration Area and the Napa River until eventually reaching the Silverado Trail N and Meadwood Lane intersection. A diagram of the road extension is provided below for reference and in the attached markup.
November 25, 2025
STREETSCAPE DESIGN
The of the crown on the levee is 48 feet wide, and the planned Adams Street cross-section is 44 feet which will sit on the crown with an additional 2’ of existing levee on either side. The proposed roadway will consist of two 11’ travel lanes, a 10’ shared-use path, and two 6’ shoulders. Guardrails are expected on either side of the travel lanes since the existing levee slopes are steeper than 4:1.
Below is a June 2025 version of the Proposed Typical Cross Section from the “Adams Street Conceptual Plan”. To match the above plan, the following updates are required:
- The curb and gutter along the shared use path will be removed and the path will be placed atgrade with the travel lanes to allow stormwater sheet flow off the side of the levee - The right-side guardrail will be placed between the shared use path and the travel lane to protect the shared-use path from adjacent traffic
- The right-side shoulder will remain to the right of the shared use path Where the street crosses bridge structures, the cross-section would look similar to the one above consisting of:
- Two 12’ Travel Lanes
- One 12’ Shared Use Path
- Two 3’ Shoulders with Sidewalls/Guardrails
42’ Total Structure Width
The existing top of levee elevation is 221.2 per record drawings, which is approximately 1.2' above the FEMA base flood elevation on the outboard side of the levee. We anticipate that the top of roadway elevation would need to be set at approximately elevation 227 to allow for adequate structure depth and freeboard to the existing FEMA base flood elevation. An embankment should be considered where the viaduct structure connects to the top of levee and to the Silverado Trail/Meadwood intersection.
The extent of the embankment should be minimized to avoid displacement of floodwaters. This
November 25, 2025
embankment would serve as a transition to the viaduct structure and also allow for the roadway to start sloping up to achieve the required top of roadway structure elevation.
Hydrologic and Hydraulic study would be needed to determine allowable extent of embankment and required drainage measures to be implemented such as culverts.
STORMWATER MANAGEMENT
Under California’s Municipal Regional Stormwater Permit, provision C.3 requires stormwater runoff management for roadway projects that produce over 10,000 square feet in impervious surface [Provisions C.3.b.ii.(4)]. C.3 recommends a design strategy of directing runoff from sidewalks, walkways, driveways, and parking lots to vegetated areas [Provisions C.3.c.i.(2)(a)(v)] and that 100% of the amount of runoff identified by Provisions C.3.d be treated via LID, including infiltration, evapotranspiration, and biotreatment measures [Provisions C.3.c.i.(2)(b)].
The surroundings of the levee can be used as an LID self-retaining area, meaning stormwater could be conveyed off the paved areas directly via sheet flow. This should be facilitated by grading impervious surfaces to pervious surfaces at a maximum ratio of 2:1. Flowlines in this area and under the viaduct can be viewed on the attached markup.
Addition of the paved roadway atop the levee will create new impervious surface and result in an incremental increase in stormwater runoff. The rate of runoff should be reviewed to verify that the existing detention basin and pump station on the inboard side of the levee have adequate capacity for the additional runoff.
OTHER CONSIDERATIONS
Other items include geotechnical and environmental design considerations:
- The existing top of levee elevations should be maintained when building the new roadway to avoid compromising the FEMA accreditation for the levee. - Due to asphalt concrete pavement being heavier than existing natural soil, geotechnical review will need to be completed to determine if settlement will become a concern with the additional weight. Vehicular loading (live load) should also be evaluated and added to the dead load of the pavement section. One method to compensate for settlement may be to raise grades for the proposed roadway.
- Where the roadway diverges from the top of the levee and extends toward the Napa River, a viaduct structure is anticipated to be constructed. This structure would pass through a Habitat Restoration area which is permanently preserved by a conservation agreement under the Land Trust of Napa County. Environmental permitting specialists should be consulted to advise on the implications of constructing a roadway structure through this area. A roadway alignment west of the Habitat Restoration area may be considered to avoid the area.

St. Helena Streets Master Plan
Re: Oak Avenue Extension Acquisition Estimate
1. Assumed land values on a per-acre basis are informed by the Economic & Planning Systems (EPS) analysis memorandum delivered on December 17, 2025, and are used as inputs for planning-level cost estimation rather than site-specific appraisals.
2. The assumed right-of-way (ROW) width of 60 feet reflects the conceptual design identified in the 2001 Highway 29 Specific Plan and is used as a consistent planning assumption for estimating potential acquisition needs.
3. Where the proposed alignment is anticipated to divide a parcel such that the remaining portion would likely not support development or economically viable use, the estimate assumes acquisition of both the ROW area and the additional remainder area that is presumed to be unviable for development.
4. Where the alignment is not expected to impair the parcel’s ability to support reasonable economic use, the acquisition estimate assumes only the land area within the conceptual 60-foot ROW, calculated based on the length of the alignment through the parcel.
5. Judgments regarding the potential viability of remainder parcels are made at a conceptual, planning level for the purpose of estimating costs only and do not constitute legal determinations.
6. Land values reflect prevailing market conditions for broadly comparable properties in St. Helena at the time of analysis and are presented in current (noninflated) dollars.
7. The acquisition estimate includes land acquisition only and excludes improvements, relocation assistance, utility relocation, environmental mitigation, legal costs, and construction-related expenses.
Memorandum
To: Anjulie Palta, Toole Design Group
From: Jason Moody and Rosanna Ren, Economic & Planning Systems Subject: St. Helena Right-of-Way Land Acquisition Cost Estimates EPS #251075
Date: December 17, 2025
This memorandum summarizes the methodology and resulting estimates for right-of-way land acquisition costs needed for the Oak Avenue extension project proposed in the St.
Helena Streets Master Plan. The analysis has been prepared by Economic & Planning Systems (EPS) as part of a consultant team led by Toole Design Group and retained by the City of St. Helena to prepare the Streets Master Plan.
The proposed Oak Avenue extension improvements included in the Plan would connect Mitchell Drive to Grayson Avenue, running parallel to Highway 29, and require the acquisition of several largely undeveloped land parcels. EPS estimated the likely land acquisition costs based on readily available data of comparable sales in the region. The information is designed to support the planning process and does not constitute a formal appraisal for any specific site.
Summary of Results
Table 1 below summarizes the sites used as comparables for the cost estimate and their approximate land sale value in 2025 dollars. On average, land value is estimated at $2,254,000 per acre, with a likely range of $2.1 million to $2.4 million per acre. The estimates are based on 33 land sale comparables going back to 2020 but have been adjusted for inflation and are reported in 2025 dollars.

Data Sources and Methodology
EPS evaluated property sales data from available data sources to estimate the likely “arms-length” purchase price to acquire the necessary right-of-way for the Oak Avenue extension project. Based on the City’s zoning map, the proposed Oak Avenue extension runs through land zoned High-Density Residential, Service Commercial, Public/QuasiPublic, Industrial, and Mixed-Use. As a result, EPS considered property sales covering agricultural, commercial (including mixed-use), and residential land uses, from the following sources:
• CoStar Data: EPS reviewed property sales from the CoStar Group, a subscriptionbased commercial real estate database covering both residential and commercial transactions. CoStar identified 26 land sale transactions in St. Helena from 2020 to 2025.
• Recently Completed Appraisal Reports: The City provided EPS with two land appraisal reports, which included a sample of six comparable sales in Sonoma County and Napa County.1
To ensure “apples-to-apples” comparison of land sales of different sizes and across different years, EPS converted all sale prices to 2025 dollars (adjusted using the Consumer Price Index) and presented values on a per-acre basis. Recognizing that several of the transactions included sites with structural improvements that likely affected the sale value, EPS made further adjustments to estimate the portion of the sale price that accounts for the land value only. This was estimated using assessed value data from the Napa County Assessor’s Office, by taking the percentage of the AV that is the land value for each parcel and applying it to the sale price.
1 EPS removed two additional sites from analysis: One outlier which estimated a land value of $12.7 million per acre and another site for which assessed value data was not available.

Subject: Saint Helena Streets Master Plan Roadway Project Alternatives Analysis Executive Summary
This technical memorandum presents the transportation operations analysis for the proposed roadway project alternatives (hereafter referred to as “study alternatives”) under the Saint Helena Streets Master Plan. The Streets Master Plan project team considered three roadway project alternatives for transportation operations analysis. The goal is to reduce congestion along State Route 29/State Route 128/Main Street (hereafter referred to as “Main Street”), provide additional connections within the City, and support the other goals of the Streets Master Plan. The additional connections will enhance emergency response by providing additional access routes and adding redundancy for emergency vehicle routing. The dispersal of motor vehicle volumes will improve the multimodal environment and provide a more comfortable experience for all users. The roadway project alternatives will incorporate traffic calming measures and signage to reinforce the intended functions of the new connections per the Streets Master Plan.
The study alternatives include the following:
• Adams Street extension from its current eastern terminus at 899 Adams Street to Silverado Trail via a new bridge over the Napa River
• Oak Avenue extension between Mitchell Drive and either Grayson Avenue or Charter Oak Avenue (two southern terminus options), including a new bridge over Sulphur Creek • Pope Street Bridge improvements across the Napa River, which also includes realignment of Pope Street to meet Silverado Trail and Howell Mountain Road at a single intersection Fehr & Peers performed operations analysis using the Synchro 12 software, which considers traffic volumes, lane configurations, signal timings, and other pertinent design, traffic volume, and operational parameters contributing to intersection operations. Study intersections were analyzed using procedures and methodologies contained in the Highway Capacity Manual, 7th Edition (Transportation Research Board, 2022). Intersection operations Levels of Service (LOS) during the weekday morning (AM), weekday evening (PM), and weekend midday (MD) peak hours were evaluated to assess each study alternative’s effect on intersection operations across the City. More detailed information is presented in the Procedures and Methodologies section.
Results show that, as the new street connections and improvements provide alternative routes for travelers, providing varying levels of congestion reductions on Main Street and throughout the City.
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 2 Among the alternatives, the Oak Avenue extension (Grayson Avenue terminus) alternative offers the greatest benefit in traffic operations, followed by the Adams Street extension alternative and Oak Avenue extension (Charter Oak Avenue terminus) alternative as they offer similar congestion reduction benefits. The Pope Street Bridge improvement alternative provides more modest benefits along Main Street. Table 1 is organized into two parts that summarize the LOS results at key intersections. Table 1A presents the LOS results under Existing Conditions, Cumulative No Project, Adams Street Extension Alternative and Pope Street Bridge Improvement Alternative. Table 1B summarizes the LOS results under Oak Avenue Extension Alternative (Grayson Avenue terminus) and Oak Avenue Extension Alternative (Charter Oak Avenue terminus).

Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 5 The Adams Street extension alternative would make the Silverado Trail and Adams Street route combination a more attractive route versus No Project conditions. As shown in Table 1A, it would result in a rerouting of traffic volumes and provide congestion reductions at key intersections along Main Street, including Main Street/Pope Street-Mitchell Drive and Main Street/Grayson Avenue. While traffic volumes would increase at locations such as Main Street/Adams Street and Silverado Trail/Pope Street, these intersections are generally expected to operate at a LOS similar to the No Project scenario. The new Silverado Trail/Adams Street intersection meets traffic signal warrant requirements and is expected to operate at LOS B with traffic signal installation, and would operate similarly well if a roundabout is implemented in lieu of a traffic signal. In addition to the congestion reduction benefit, the extension is envisioned to include a shared-use path for pedestrians and bicyclists to support bicycle and pedestrian connectivity throughout the City.
The Pope Street Bridge improvement alternative would improve motorists’ driving experience on the Pope Street Bridge; therefore, it is assumed this alternative will entice more drivers to use the Silverado Trail and Pope Street route. However, because these travelers would still need to navigate existing intersections that are congested, the diversion potential is smaller than the Adams Street alternative. As shown in Table 1A, the Pope Street Bridge improvement alternative would provide modest congestion reductions at key intersections along Main Street including Main Street/Pope Street-Mitchell Drive and Main Street/Grayson Avenue. While traffic volumes would increase at intersections along Pope Street, these intersections are generally expected to continue to operate at a LOS similar to No Project conditions. However, it is noted some intersections, such as Pope Street/Starr Avenue, will need complementary improvements (e.g., traffic control configurations such as all-way stop-control) to operate at LOS C or better. The Silverado Trail/Pope Street-Howell Mountain Road intersection meets traffic signal warrant requirements and is expected to operate at LOS D or better with traffic signal installation, and would operate similarly well if a roundabout is implemented in lieu of a traffic signal. In addition to vehicle circulation improvements, the Pope Street Bridge improvement would provide upgrades to pedestrian and bicyclists facilities to strengthen the multimodal network.
The Oak Avenue extension alternative would provide a new roadway connection parallel to the most congested segments along Main Street. As shown in Table 1B, both the Grayson Avenue terminus and the Charter Oak Avenue terminus alternative would reduce traffic volumes at key intersections along Main Street, including Main Street/Pope Street-Mitchell Drive. While traffic volumes would increase at intersections along Oak Avenue, the affected intersections are expected to operate at LOS C or better. Specifically, key intersections along the extended segment of Oak Avenue, including Oak Avenue/Grayson Avenue and Oak Avenue/Charter Oak Avenue, are expected to operate at LOS C or better with side-street stop-controlled configurations. The intersections along the existing segment of Oak Avenue between Madrona Avenue and Grayson Avenue are expected to operate at LOS C or better with their existing stop control configurations (i.e. all-way stop-controlled and side-street stop-controlled). Under the Charter Oak Avenue terminus alternative, the Main Street/Charter Oak Avenue intersection meets traffic signal warrant requirements and is expected to operate at LOS C with traffic signal installation. While the traffic volumes would increase at locations along Oak Avenue, the overall volume along the corridor is expected to remain low to moderate. Wayfinding signages would be provided to improve driver awareness of the connection to key community locations, and the corridor would incorporate traffic calming measures to manage operating speeds and support a livable, multimodal street environment.
All study alternatives would allow drivers to utilize alternative routes and thus reduce congestion along Main Street within the City of Saint Helena. The Oak Avenue extension (Grayson Avenue
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 6 terminus) alternative provides the highest congestion reduction benefits across the study alternatives, as it provides the shortest re-route from Main Street, and enables drivers to travel on a route directly parallel to Main Street. The Oak Avenue extension (Charter Oak Avenue terminus) alternative also provides congestion reduction benefits. However, compared to the Grayson Avenue terminus alternative, the congestion reduction benefits are more modest because the extension will be shorter distance and drivers would still experience delays south of Charter Oak Avenue along Main Street before turning on to Oak Street. The Adams Street extension alternative provides the second highest congestion reduction benefits, as it provides a high-quality route to directly bypass congestion along Main Street. The Pope Street Bridge alternative offers a more comfortable driving experience for drivers willing to take the combination of Silverado Trail and Pope Street; however, drivers would still experience delays north of Pope Street along Main Street. By reducing vehicle demand and providing congestion reductions along Main Street, the study alternatives would also improve the multimodal environment, making the travel experience for all users more comfortable and safer.
Additional descriptions are provided in the Operations Assessment section. Appendix A presents the delays and LOS for all study intersections for reference. Appendix B presents the collected counts.
Appendix C presents the calculations worksheets.
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 7 Introduction
This technical memorandum presents the transportation operations analysis for the street extension and/or improvement study alternatives under the Saint Helena Streets Master Plan. The operations assessment for the City’s General Plan Update 2040 was completed in 2018; the Saint Helena General Plan Update 2040 (hereafter referred to as “General Plan”) was adopted in 2019. The analysis builds upon the transportation operations analysis and traffic operations analysis models prepared for the adopted General Plan and has been prepared in a manner consistent with the traffic operations analysis for the adopted General Plan and Environmental Impact Report (EIR). The work updated the Synchro traffic operations analysis model developed for the General Plan, incorporates revised traffic volume forecasts reflecting the roadway project build-out scenarios, and summarizes the traffic operations results of study alternatives.
Project Description
The existing transportation infrastructure and development pattern in the City of Saint Helena supports a walkable community and provides access to local and regional destinations. However, the City faces challenges including congestion along Main Street, limited low-stress multimodal options for residents and visitors, and intersection LOS grades that frequently fall below the standards set forth in the General Plan. The Saint Helena Streets Master Plan (hereafter referred to as “Streets Master Plan”) project aims to produce a conceptual design plan for the transportation network throughout the City, except for the Downtown Specific Plan (“DSP”) area. The Streets Master Plan will enhance and supplement the City’s circulation element goal of encouraging development of a multimodal transportation network and supportive land use decisions to boost alternative modes of transportation.
At the direction of the City, the Streets Master Plan project team considered three street extension alternatives for transportation operations analysis. The goal is to reduce traffic demand on Main Street and provide additional connections within the City. The additional connections will enhance emergency planning and response by providing additional access routes and adding redundancies for emergency vehicles. The study alternatives include the following:
• Adams Street extension from its current eastern terminus at 899 Adams Street to Silverado Trail via a new bridge over the Napa River
• Oak Avenue extension between Mitchell Drive and either Grayson Avenue or Charter Oak Avenue (two southern terminus options), including a new bridge over Sulphur Creek • Pope Street Bridge improvements across the Napa River, which also includes realignment of Pope Street to meet Silverado Trail and Howell Mountain Road at a single intersection Figure 1 presents the study intersections and proposed extensions.

Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 9 Procedures and Methodologies
The study intersections were analyzed using procedures and methodologies contained in the Highway Capacity Manual, 7th Edition (Transportation Research Board, 2022). These methodologies were applied using Synchro 12 software, which considers traffic volumes, lane configurations, signal timings, and other pertinent design, traffic volume, and operational parameters contributing to intersection operations.
The following describes specific inputs, model parameters, and other aspects of Synchro modeling based on data collection efforts.
• Peak hour volumes collected at the study intersections in 2024 and 2025 were used for Existing Conditions. Local schools were in session and weather conditions were clear when the data was collected. Appendix B presents the collected counts.
• Volume forecasts were based on the General Plan transportation operations analysis buildout forecasts. For the study alternatives, forecasts were developed using output from the most appropriate version of the Solano-Napa Activity Based Model (SNABM). Specifically, the output was used to determine shifts in traffic volumes throughout the City resulting from the study alternatives, along with manual adjustments informed by travel time and traffic volume elasticity assessments.
• Intersection configurations were entered based on aerial imagery and anticipated complementary improvements.
• The observed existing conditions weekday morning, weekday evening, and weekend midday peak hour factor (PHF), which is a measure of peaking of traffic volumes during the busiest 15- minutes of the peak hour (lower values represent more peaking) at each intersection, was used. • The observed weekday morning, weekday evening, and weekend midday peak hour heavy vehicle percentage (HVP) at each intersection was used. Observed bicycle and pedestrian volumes were used. However, in cases where the HVP was two percent or less, a minimum of three percent was applied to account for potential variations in vehicle composition.
Level of Service Definition
This study analyzes intersection operations using automobile delay and LOS as the primary measure of performance. Automobile LOS is a qualitative description of traffic flow from the perspective of motorists. The Highway Capacity Manual, 7th Edition (HCM) defines six levels of service, from LOS A representing the least congested traffic conditions to LOS F representing the most congested traffic conditions. These grades represent the perspective of drivers and are an indication of the comfort and convenience associated with driving, as well as speed, travel time, traffic interruptions, and freedom to maneuver.
The HCM methodology determines the LOS at intersections by calculating the weighted average delay per vehicle. At unsignalized side-street stop-controlled intersections, LOS is also reported for the worst approach. Table 2 displays LOS criteria for both signalized and unsignalized intersections.

Intersection Substantial Operational Effect Criteria
Intersection operations LOS was evaluated to assess the study alternatives’ effect on intersection operations and identify the potential need for enhancements to the transportation network. Based on the Transportation Performance Measures of the adopted General Plan, the City has augmented performance measures to look beyond the traditional automobile LOS for the purpose of developing a meaningful nexus to improve multimodal circulation and provide congestion reductions. However, for the purpose of evaluating intersection operations for automobile LOS to illustrate the operational effect between study alternatives, thresholds consistent with the Saint Helena General Plan Update 2035 (April 2016), the Saint Helena General Plan Update 2040 Environmental Impact Report (October 2018), and the Napa County General Plan (February 2019) were used to inform if the study alternatives would result in unacceptable operations. In City of Saint Helena, the standard is LOS C for signalized and unsignalized intersections, except along Main Street where LOS D for signalized intersections shall be permitted. For intersections outside the City of Saint Helena boundary, the standard is LOS D at signalized intersections. Complementary improvements (e.g., traffic control configurations such as traffic signal or roundabout) were tested at key new intersections with the study alternatives.
Signal Warrant Analysis
The peak hour signal warrants (Warrant 3A and Warrant 3B) from the Manual on Uniform Traffic Control Devices (MUTCD) were used to determine if a traffic signal is warranted at the new intersections.1
The warrants are based on volumes under cumulative conditions with respective study alternatives.
1 Warrant 3A and 3B are more rigorous than warrant 4C and were therefore selected as the basis for the signal warrant analysis. While the community’s population falls below the typical thresholds for 3A and 3B, applying these warrants at the planning level provides a more conservative analysis. This is especially relevant given the community’s tourist population, where seasonal and visitor traffic can result in volumes that exceed what the resident population alone would suggest.
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 11 Operations Assessment
Existing Conditions
Fehr & Peers performed operations analysis for intersections under Existing Conditions, based on the traffic volumes and lane configurations shown in Figure 2. The analysis found that while most intersections operate acceptably under Existing Conditions, intersections that operate unacceptably during at least one peak hour include the following:
• Main Street/Pratt Avenue
• Main Street/Elmhurst Avenue
• Main Street/Pope Street-Mitchell Drive
• Main Street/Charter Oak Avenue
• Main Street/Spring Street
A summary table presenting the delays and LOS for all study intersections is provided in Appendix A for reference.

Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 13 Cumulative Conditions
Fehr & Peers performed Cumulative Conditions intersection operations analysis based on the traffic volumes and lane configurations shown in Figure 3. Under Cumulative Conditions without study alternatives, the analysis found that, because traffic volumes are expected to grow between Existing Conditions and Cumulative Conditions, several additional intersections operate unacceptably during at least one peak hour.
Intersections that were operating unacceptably during at least one peak hour under Existing Conditions and would continue to operate unacceptably include the following:
• Main Street/Pratt Avenue
• Main Street/Elmhurst Avenue
• Main Street/Pope Street-Mitchell Drive
• Main Street/Charter Oak Avenue
• Main Street/Spring Street
In addition, the following intersections which were operating acceptably under Existing Conditions are expected to degrade to unacceptable operations during at least one peak hour under Cumulative Conditions:
• Main Street/Adams Street
• Main Street/Hunt Avenue
• Main Street/Grayson Avenue
• Main Street/Sulphur Springs Avenue
• Pope Street/Paseo Grande Drive-College Avenue
• Silverado Trail/Pratt Avenue
• Silverado Trail/Pope Street
• Main Street/Mills Lane
• Main Street/Spring Street
As the study alternatives provide new roadway connections, traffic volumes were assumed to reroute and provide various degrees of congestion reductions for Main Street. Figure 4, Figure 5, and Figure 6. Reference source not found. present the expected rerouted traffic volume under each study alternative. Figure 7, Figure 8, and Figure 9. Reference source not found. present the traffic volume and lane configuration under each study alternative. Figures for the Oak Avenue extension alternative are organized into two parts (A and B) for the Grayson Avenue terminus and Charter Oak Avenue terminus alternatives.

Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 23 Adams Street Extension Alternative
The extension of Adams Street from its current eastern terminus at 899 Adams Street to Silverado Trail via a new bridge over the Napa River will provide a new east-west connection between Silverado Trail and Main Street. Because a portion of this new connection extends outside the City boundary, the extension of Adams Street will provide a new connection benefiting both the City and the County.
As such, the extension will result in a rerouting of traffic volumes from Main Street to Silverado Trail and Adams Street because it will provide a new, desirable route to bypass congestion on Main Street.
Additionally, it is also expected to reroute traffic volumes from Pope Street to Silverado Trail and Adams Street.
Intersection operations analysis results with Adams Street extension illustrate that the extension will provide congestion reductions along Main Street. Notably, at Main Street/Pope Street-Mitchell Drive, the LOS is improved from LOS F to LOS E for the weekday AM, weekday PM, and weekend MD peak hours; this indicates that (at the whole-intersection level), the intersection will operate at-capacity instead of over-capacity with the construction of the Adams Street extension. In addition, the following intersections are projected to improve from unacceptable operations without the Adams Street extension to acceptable operations with the extension for at least one peak hour:
• Main Street/Adams Street
• Main Street/Hunt Avenue
• Main Street/Grayson Avenue
The extension of Adams Street will introduce a new intersection at Silverado Trail/Adams Street. The new intersection is expected to operate at LOS B with traffic signal installation, and would operate similarly well if a roundabout is implemented in lieu of a traffic signal.
The rerouting of traffic volumes would increase traffic volume at additional locations, including segments along Silverado Trail between Pope Street and Adams Street, and Adams Street between Silverado Trail and Main Street. As such, traffic volume is expected to increase at intersection locations such as Main Street/Adams Street and Silverado Trail/Pope Street. However, the analysis indicates that these intersections are still expected to operate at a LOS similar to or better than the No Project scenario, with the exception of Silverado Trail/Howell Mountain Road which worst approach delay would degrade from a high LOS C to a low LOS D for the weekday PM peak hour.
In addition to improving vehicular circulation, the extension is envisioned to include a shared-use path for pedestrians and bicyclists to support bicycle and pedestrian connectivity throughout the City.
Oak Avenue Extension Alternative
The extension of Oak Avenue – either between Mitchell Drive and Grayson Avenue or between Mitchell Drive and Charter Oak Avenue - will provide a new north-south connection within the City along with a new crossing of Sulphur Creek. The extension provides a new, desirable route to bypass the most congested stretch of Main Street and balance the existing high demand for Main Street. It will shift traffic volume traveling north and south along Main Street and the Valley View Street-Crane Avenue corridor to the new Oak Avenue extension.
Intersection operations analysis results with Oak Avenue extension alternative illustrate that the extension, with either southern terminus options, will generally provide improved operations along
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 24 Main Street. For example, at Main Street/Pope Street-Mitchell Drive, the LOS is improved from a high LOS F to a LOS E or low F for the weekday AM, weekday PM, and weekend MD peak hours.
This indicates that (at the whole-intersection level), the intersection will operate at-capacity instead of over-capacity with the construction of the Oak Avenue extension.
In addition, the following intersections are projected to improve from unacceptable operations without the Oak Avenue extension to acceptable operations with the extension for at least one peak hour:
• Main Street/Adams Street
• Main Street/Hunt Avenue
• Main Street/Grayson Avenue (Grayson Avenue terminus alternative only) While traffic volumes would increase at intersections along Oak Avenue, the affected intersections are generally expected to operate at LOS C or better. Specifically, key intersections along the extended segment of Oak Avenue, including Oak Avenue/Grayson Avenue and Oak Avenue/Charter Oak Avenue, are expected to operate at LOS C or better with side-street stop-controlled configurations. The intersections along the existing segment of Oak Avenue are expected to operate at LOS C or better with their existing stop control configurations (i.e. all-way stop-controlled and side-street stop-controlled).
Between the Oak Avenue extension (Grayson Avenue terminus) alternative and Oak Avenue extension (Charter Oak Avenue terminus) alternative, the Charter Oak Avenue terminus provides congestion reduction benefits in a similar manner to the Grayson Avenue terminus alternative.
However, compared to the Grayson Avenue terminus alternative, because the Charter Oak Avenue terminus will extend Oak Avenue over a shorter distance, drivers are expected to experience some delays south of Charter Oak Avenue along Main Street before turning on to Oak Street. Therefore, the congestion reduction benefits would be more modest. For example, at Main Street/Pope StreetMitchell Drive, while the delay is expected to improve substantially with the extension, the weekday AM peak hour is expected to operate at LOS F rather than LOS E; however, the average delay is slightly above the LOS E/F threshold of 80 seconds, indicating that the signal operates only slightly over-capacity. In addition, the Main Street/Charter Oak Avenue intersection meets traffic signal warrant requirements and is expected to operate at LOS C with installation of a traffic signal.
It is noted that the rerouting of traffic volumes would affect traffic movements at additional locations including segments along Main Street between the Oak extension southern terminus (Grayson Avenue or Charter Oak Avenue) and Sulphur Springs Avenue, as volumes are attracted from Sulphur Springs Avenue to take the new Oak Avenue extension. While delays are expected to fluctuate given the shifts in turning movements, affected intersections are expected to operate at a LOS level similar to No Project conditions.
While the traffic volumes would increase at locations along Oak Avenue, the overall volume along the corridor is expected to remain low to moderate. Wayfinding signages would be provided to improve driver awareness of the connection to key community destinations, and the corridor would incorporate traffic calming measures to manage operating speeds and support a livable, multimodal street environment.
Saint Helena Streets Master Plan Roadway Project Alternatives Analysis | 25 Pope Street Bridge Improvement Alternative
The Pope Street Bridge alternative includes the improvement of the Pope Street Bridge and the realignment of Pope Street to create a single intersection with Silverado Trail and Howell Mountain Road. Improving the Pope Street Bridge will enhance the driving experience as the widened Pope Street Bridge will be more comfortable to navigate. As such, it is expected to attract drivers traveling north and south along Main Street to use a combination of Silverado Trail and Pope Street. However, because these travelers would still need to navigate existing intersections that are congested north of Pope Street, the diversion potential is smaller than the Adams Street alternative and the Oak Avenue alternative.
Intersection operations analysis results with the Pope Street Bridge Improvement alternative indicate that the alternative will provide modest congestion reductions along Main Street. For example, the delays would decrease at Main Street/Pope Street-Mitchell Drive but the LOS would maintain a grade of LOS F for the weekday AM, weekday PM, and weekend MD peak hour; this indicates that, after construction of the Pope Street Bridge improvement, the Main Street corridor would continue to operate in an over-capacity condition. No intersections are projected to improve from unacceptable operations without the Pope Street Bridge improvement to acceptable operations with the improvement.
The Pope Street Bridge Improvement alternative includes realignment of Pope Street to meet Silverado Trail and Howell Mountain Road at a single intersection. This new intersection will need complementary improvements (e.g., traffic control configurations such as traffic signal or roundabout) to operate at LOS D or better.
While traffic volumes would increase at intersections along Pope Street, these intersections are generally expected to continue to operate at a LOS level similar to No Project conditions. However, intersections such as Pope Street/Starr Avenue will need complementary improvements (e.g., traffic control configurations such as all-way stop-controlled) to operate at LOS C or better.
In addition to improving traffic operations, the Pope Street Bridge Improvement alternative would improve walking and biking infrastructure, supporting an enhanced multimodal transportation network.

Notes: * Silverado Trail/Howell Mountain Road-Pope Street has been modeled as one signalized intersection under Pope Street Bridge Improvement Alternative Scenario as an operational improvement. The County may also consider converting this intersection to a roundabout as described in the Napa County General Plan. ** Main Street/Charter Oak Avenue has been modeled as one signalized intersection under the Oak Avenue Extension (Charter Oak Avenue terminus) Alternative Scenario as an operational improvement. 1. Delay for signalized and all-way stop-controlled intersections presented as whole-intersection average delay. Delay for side-street stop-controlled intersections presented as whole-intersection average delay (delay on worst movement or single-lane approach).
2. LOS per Highway Capacity Manual, 7th Edition
3. Bold indicates unacceptable operations.
4. AWSC = All-Way Stop-Controlled, SSSC = Side-Street Stop-Controlled.
