1. INTRODUCTION

Pinellas County retained Pennoni to prepare a Preliminary Engineering Report (PER) to address roadway, drainage, pedestrian, and bicyclist safety concerns in the Anclote Road corridor between Anclote

Boulevard and Alternate US 19.

1.1 Project Description

The project area currently experiences localized flooding along Anclote Road, Center Avenue, Savannah

Avenue, and other locations along the project limits. The existing roadway pavement in many locations is also in poor condition and requires rehabilitation. The project area has numerous adjacent sites of environmental concern and discharges to the Anclote River.

Anclote Road is a continuous 2.4-mile two-lane collector road serving under-developed industrial and commercial areas, employment centers, and residential areas in unincorporated Pinellas County and the

City of Tarpon Springs. The County has identified this area as a Target Employment Center for economic development, allowing increased density for uses such as manufacturing, office, and research & development. Forward Pinellas Target Employment and Industrial Land Study (TEILS) 2022 update identifies the project area as a "Local" Target Employment Center defined as follows: TEC Local – These areas house smaller scale manufacturers and artisan users with industrial and warehouse space needs.

The TEC Local designation would allow for flex-space and mixed-use in conjunction with local sub-area planning efforts (visioning studies, special area plans, etc.).

The transportation objectives for improving this corridor are to provide multimodal access to industrial, workforce, and residential areas, improve safety, and enhance stormwater management. The project will also provide improved access to Elfers and Coastal Anclote Trails.

1.2 Purpose and Need

1.2.1 Purpose

The Preliminary Engineering Report (PER) addresses pedestrian and bicyclist safety concerns by evaluating a combination of a 10-foot-wide shared-use path, sidewalks, and on-street bike lanes within the project limits. The PER also assesses improvements to the roadway and drainage in the corridor.

The report will assist the County in determining the scope, budget, and schedule of future improvements based on the following factors:

• Safety

• Right-of-way Constraints

• Utility Conflicts

• Drainage and Environmental Impacts

• Floodplain impacts

• Construction Costs

• Long Range Transportation Plan (LRTP) Consistency

1.2.2 Need

The need for improvements focuses on enhancing safety and mobility for all modes of transportation, including motor vehicles, pedestrians, and bicyclists. Residents and corridor users have identified multiple areas of concern:

• Improved corridor safety.

• Enhanced mobility throughout the corridor.

• Enhanced multimodal transportation.

• Improved drainage.

a. Safety

The posted speed limit on Anclote Road is 35 miles per hour. This roadway is a designated unrestricted truck route and an essential east-west collector roadway in Pinellas County's transportation network. There are limited pedestrian and bicycle amenities within the project limits. A total of 20 crashes were reported between 2019 and 2022. The crashes include eight injuries and 12 property damage-only crashes, with no fatal crashes reported.

b. Social and Economic Demands

The established community and businesses surrounding the project corridor have shaped the character of Anclote Road. The poor multimodal levels of service hinder economic development and prosperity in the study area. The County has identified this area as a Target Employment

Center for economic development, allowing increased density for uses such as manufacturing, office, and research & development.

c. Consistency with Transportation Plans

The Forward Pinellas 2045 LRTP identifies a network of sidewalks, bicycle lanes, and trails for

Pinellas County. Enhancing the multimodal accommodations along the Anclote Road corridor will connect multiple non-motorized facilities, and the proposed improvements align with the goals outlined in the 2045 LRTP.

1.2.3 Project Location and Phases

The project location and study phases are shown in Figure 1.

a. Phase Area 1

The limits are from Alternate US 19 to the intersection of Anclote Road and L&R Industrial

Boulevard, including outfalls. It also includes Center Avenue from Anclote Road to Fulton Street.

b. Phase Area 2

The limits are from the intersection of Anclote Road and L&R Industrial Boulevard to the intersection of Anclote Road and Wesley Avenue, including outfalls. It also includes Savannah

Avenue from Anclote Road to Brady Road and Brady Road to the Work Release Center.

c. Phase Area 3

The limits are from the 90-degree bend by Wesley Avenue and Anclote Road Intersection to

Anclote Boulevard, including outfalls.

Figure 1 – Project Location and Phase Areas

1.3 Related Projects, Studies, and Resources

• Anclote River Watershed Management Plan and Watershed Evaluation, 2023.

• Pinellas County and City of Tarpon Springs GIS sources.

2. EXISTING CONDITIONS

Anclote Road is a two-lane roadway and primarily serves as a vital east-west thoroughfare within Pinellas

County's transportation network, connecting Anclote Boulevard to Alternate US 19. The project area's future land uses include industrial, commercial, and residential developments. The project improvements will improve connections to businesses and residents and Alternate US 19. The area is growing, and undeveloped areas will provide additional employment growth opportunities.

2.1 Existing Roadway Characteristics

2.1.1 Location and Functional Classification

The project is in northern Pinellas County, and its limits extend along Anclote Road from Anclote Boulevard to Alternate US 19, covering approximately 2.4 miles with a posted speed of 35 mph and varying right-of-way. Anclote Road is classified as a collector road. The alignment has four 90-degree curves and no signalized intersections within the project limits.

2.1.2 Access Management

Anclote Road is a two-lane undivided roadway. Its layout permits non-restrictive access management, allowing turns at any point to enter side streets, businesses, or residential driveways within the project limits.

2.1.3 Evacuation Route

Anclote Road is not an evacuation route. Alternate US 19 is an evacuation route.

2.1.4 Typical Sections

The existing typical section for the Anclote Road corridor within the project limits consists of two 10-foot travel lanes accompanied by roadside swales and 5-foot non-continuous sidewalks along the roadway alignment (See Figure 2).

Figure 2 – Existing Typical Section. Rural Roadway with Swales and Non-Continuous Sidewalks

2.1.5 Pedestrian and Bicycle Facilities

Anclote Road has non-continuous 5-foot sidewalks with no bike lanes and paths throughout the corridor.

The project's primary goal is continuous connectivity from Anclote Boulevard to Alternate US 19. There are currently limited crosswalks or no signalized intersections within the project limits.

The improvements will allow for potential trial connections as separate projects to the Coastal Anclote

Trail and the Elfers Spur Trail (See Figure 3).

Figure 3 – Potential Trail Connections

2.1.6 Transit Facilities

The Pinellas Suncoast Transit Authority (PSTA) does not serve the Anclote Road study area. The closest transit route is Route 18, which operates on Alternate US 19 at the beginning of the project limits. This route provides bus service and follows Alternate US 19 north and south. PSTA also offers Routes 18, 66L, and JCT approximately 0.33 miles south of Anclote Road and Alternate US 19 (See Figure 4).

Figure 4 – PSTA Route Map

2.1.7 Existing Right of Way

The right-of-way varies from 40 to 73 feet (See Figure 5). Most right-of-way is 66 feet wide for Phase Areas

1 and 2. The right-of-way reduces to 40 feet wide just south of Wacassassa Street in Phase Area 3.

Figure 5 – Existing Right-of-way

2.1.8 Horizontal and Vertical Alignment

The existing horizontal alignment is east-west and north-south through four 90-degree curves starting at

Anclote Boulevard and ending at Alternate US 19. The topography within the corridor ranges from an elevation of 4 feet to an elevation of 14 feet. The vertical datum is NAVD 88. The County Transportation

Manual indicates that the minimum edge of pavement elevation should be five feet above mean sea level.

This requirement will significantly impact wetlands, floodplains, adjacent properties and right-of-way and should be further evaluated during the final design phase.

2.1.9 Geotechnical Data

A Web Soil Survey through the United States Department of Agriculture (USDA) Natural Resources

Conservation Service was utilized to identify the soil types within the project limits. Figure 6 represents the various soil types, organic soils, and seasonal high water table levels within the project limits. Table 1 shows the soil groups within the project limits. Table 2 was created to analyze the soil data further by establishing a 300-foot buffer (150 feet north and south of the Anclote Road centerline). The table indicates the soils within the project area, with the largest percentage comprising Astatula, Tavares Urban, Myakka Urban Land, Matlacha and St. Augustine Urban.

Certain soil types, such as clays, silts, and muck, characterized by poor drainage and organic content, are unfavorable for constructing the proposed culvert crossing before the first curve west of Alternate US 19.

These soils can potentially undergo shrinkage and swelling, posing challenges during construction. If encountered during construction, this soil type should be removed per FDOT Standard Plans Index 120-

002 and utilized per FDOT Standard Plans Index 120-001.

The depths to the encountered groundwater table (when encountered) ranged from approximately 2.5 to 6.4 feet below the existing ground surface at the locations of the borings performed. The groundwater table was not encountered within the depths explored at some of the borings.

Based on a review of USDA soil information and the field exploration, the historical Seasonal High

Groundwater Table (SHGWT) levels within the project limits range from at or above the ground surface to

3½ feet below existing grades. According to the results of the borings performed for the project, the

SHGWT levels range from approximately ½ foot to greater than 5½ feet below existing grades. At the locations of borings SH-4 and SH-7, the SHGWT levels were not determined due to a general absence of geotechnical indicators in the soil samples. Refer to Appendix F for the geotechnical information.

2.1.10 Signalizations and Intelligent Transport System (ITS)

There are no signals within the project limits. Additionally, it is important to note that the Anclote Road improvement corridor currently lacks ITS infrastructure, and the Pinellas County ITS/ATMS Master Plan does not outline any future provisions for ITS infrastructure along Anclote Road.

2.1.11 Pavement Conditions

The geotechnical field exploration encountered asphalt pavement thicknesses ranging from approximately 1.0 to 10.0 inches underlain by base materials consisting of brick and/or limerock of varying thicknesses.

Based on visual observations and core locations, the pavement condition noted along the project alignment is "Fair" to "Poor" condition. The condition at each core location and core photographs are shown in Appendix F.

During the final design, the FDOT Flexible Pavement Design Manual and Pinellas County guidelines for road rehabilitation projects should be utilized to ensure an adequate Structural Number (SN) value is obtained based on the corresponding ESAL value over the design life of the roadway.

2.1.12 Railroads

There are no visible railroad tracks or crossings within the project limits. However, according to the 2009

Pinellas County Railway Network, a railway track that was within the project limits may now be abandoned

(See Figure 7).

Figure 7 – 2009 Pinellas County Railway Network

2.1.13 Utilities

Numerous utilities are located within the Anclote Road right of way from Anclote Boulevard to Alternate

US 19. The following utilities, shown in Table 3, exist within the limits of the Anclote Road Study Corridor.

2.1.14 Bridges and Culvert Cross Drain Structures

There are no bridges within the project limits. Cross drains within the project limits range from 24 inches to 42 inches. Refer to Section 2.1.20 for additional information.

2.1.15 Lighting

The intersections along Anclote Road at Anclote Boulevard, L&R Industrial Boulevard, and Alternate US

19 within the project limits have high-pressure sodium or metal halide lighting.

2.1.16 Land Use

Existing land use in the area varies throughout the project limits. Residential development, including single-family residences and Hickory Point Mobile Home Park, is most common from south of Anclote Blvd to Meyers Cove Drive. Two large undeveloped parcels owned by Stauffer Management Company LLC are located north and south of Anclote Road from Myers Cove Drive to the turn near Wesley Avenue between

Savannah Avenue and Windy Bay.

A recent residential development, with light industrial and commercial land uses, characterizes this section of the project corridor. Residential and commercial development, primarily boat storage and marina services, occur in the remaining section of the project corridor.

Anclote Road provides a key connection for businesses and residents to Alternate US 19. Future land use is consistent with existing land use. Large areas are designated for industrial uses, and undeveloped areas provide opportunities for employment growth in the County.

Tarpon Springs's future land use is shown in Figure 8, and Pinellas County's future land use is shown in

Figure 9.

2.1.17 Target Employment Centers for Economic Development

The project corridor is located within a Target Employment Center for economic development, as shown in Figure 10. This designation permits a 100% floor area ratio intensity bonus for manufacturing, office, and research and development uses.

Figure 10 – Future Land Use (Pinellas County)

2.1.18 Traffic and Levels of Service

According to Forward Pinellas's 2021 Facility Level of Service Report, the Average Annual Daily Traffic for

Anclote Road from Anclote Boulevard to Alternate US 19 is 3,200 vehicles per day. Level of Service (LOS) was calculated using guidelines identified by the FDOT Quality/Level of Service Handbook, FDOT

Generalized Tables, FDOT ArtPlan, and the Highway Capacity Manual. Based on these traffic counts, the current Level of Service (LOS) for Anclote Road is "C." For the Anclote Road and Alternate US 19, the through movements have a LOS from "D" to "F," according to the report (See Appendix G).

2.1.19 Transportation and Traffic Analysis

Field reviews were conducted to observe traffic flow, identify existing traffic control, and note general operations at all roadway segments and intersections within the project limits. A GIS application was utilized to record (and photograph) safety, traffic operations, and design issues associated with the project and to consider incorporating enhanced safety elements for all users along Anclote Road. A link to this field review database and graphical presentation is provided here:

Refer to Appendix G for the project Transportation/Traffic Analysis.

2.1.20 Existing Drainage

The project area currently experiences localized flooding along Anclote Road, Center Avenue, Savannah

Avenue, and other locations along the project limits.

The existing rural roadway drains via roadside swales, storm pipes, and outfalls (See Figure 11).

a. Phase Area 1

Anclote Road and Highland Avenue intersection is the high point elevation of 14.07 feet along the eastern portion of Phase Area 1. To the east of Highland Avenue, the drainage flows along the edge of the roadway and shallow swales to the intersection of Alternate US 19. There is a low point just west of Alternate US 19, and the water is ponding on the south side of Anclote Road at

Station 424+50. Alternate US 19 is an FDOT roadway with a storm system discharging to Outfall 1 that drains south to the Anclote River.

To the west of Highland Avenue, the drainage flows via inlets, side drains and swales to the wetland area east of Outfall 2 at Station 404+75.

From the Anclote Road and L&R Industrial Boulevard intersection, the drainage flows south via inlets, side drains and swales to a 24-inch cross drain at Station 210+10 and discharges to the tidal wetland area on the east side.

https://gis.pennoni.com/portal/apps/webappviewer/index.html?id=482c6c0fe7a44203b2ba546c79b86025 https://gis.pennoni.com/portal/apps/webappviewer/index.html?id=482c6c0fe7a44203b2ba546c79b86025

The segment from Station 400+26 to 407+23 will drain to Outfall 2 at Station 404+75 via inlets, side drains and swales.

Outfall 2 is a 42-inch corrugated metal pipe, and the area to the north is a tidal wetland. The outfall area also has organic soils based on the geotechnical investigation that need consideration when replacing the corrugated metal pipe.

Center Avenue is experiencing localized flooding between Anclote Road and Fulton Street due to depressional areas at Station 12+79 and a lack of drainage inlets and pipes.

Figure 11 – Drainage Flows and Outfalls

b. Phase Area 2

From north of the Anclote Road and Wesley Avenue intersection at Station 47+69, the drainage flows south via roadside swales, inlets, and storm pipes to Outfall 3 at Station 71+58.

From west of the Anclote Road and L&R Industrial Boulevard intersection at Station 92+12, the drainage flows west via roadside swales, inlets, and storm pipes to Outfall 3.

Outfall 3 is a 60-inch reinforced concrete pipe draining south to the Anclote River.

Savannah Avenue is experiencing localized flooding between Anclote Road and Brady Road due to the lack of drainage inlets and pipes. The flow is from Brady Road to Anclote Road and discharges to Outfall 3.

c. Phase Area 3

This Phase Area has an inadequate drainage system and narrow right-of-way. The drainage from the Anclote Road and Anclote Boulevard intersection at Station 11+13 drains southeast along the roadway edge to a depressional area at the Wacassassa Street intersection at Station 17+30. The roadway from approximately Station 27+72 also drains northwest along the roadway edge and shallow swales to the Wacassassa Street intersection.

The drainage from the 90-degree bend just north of Wesley Avenue at Station 47+69 drains west via shallow swales to Outfall 4.

Outfall 4 consists of triple 24-inch reinforced concrete cross drains (Station 30+75) and a single

24-inch reinforced concrete cross drain (Station 30+90) discharging south to the Anclote River.

Existing cross drains within the project limits are listed in Table 4.

2.1.21 Existing Floodplains

The Anclote Road corridor is within a designated Federal Emergency Management Administration (FEMA)

100-year flood zone. Figure 22 illustrates that a significant portion of the study corridor falls under the

Special Flood Hazard Area (SFHA) classification, specifically identified as "AE." SFHAs represent areas prone to flooding, with a 1-percent chance of being equaled or exceeded in any given year. The FEMA

100-Year Base Flood Elevation (BFE) varies within the corridor, ranging from approximately 10 ft at Anclote

Boulevard to 8 ft at Alternate US 19.

Figure 22 – FEMA 100-Year Flood Plain

2.1.22 Impaired Water Body

The project area has numerous adjacent sites of environmental concern and discharges to Anclote River.

The project area water body is identified as WBID 1440 by the Florida Department of Environmental

Protection (FDEP). This waterbody is not impaired for nutrients because the annual geometric means did not exceed the nutrient threshold more than once in a three-year period. However, it will remain in category 4e (Ongoing Restoration) because it has not attained the magnitude of the criterion for the three most recent consecutive years. It is assessed in category 4e because there are ongoing restoration activities to address the nutrient impairment. The Anclote River Watershed 4e Plan includes pollutant control measures to address the nutrient impairment in the Anclote River Estuary. This parameter will remain on the 303(d) List.

2.1.23 Contamination

A contamination Level 1 evaluation was performed in accordance with Part 2, Chapter 20 of the Florida

Department of Transportation's Project Development and Environment Manual (July 1, 2020). Along

Anclote Road, one site had a high ranking (Stauffer Chemical Co), and two had a medium ranking (Former

Gasoline Station/Tarpon Trading Company and Port Tarpon Marina Associates). Refer to Figure 23 and

Appendix H.

Figure 23 – High and Medium Ranking Contamination Sites

During the final design phase, additional review is recommended in consideration of dewatering operations that may be necessary under the National Pollutant Discharge Elimination System Generic

Permit for Stormwater Discharges from Large and Small Construction Activities. Verification testing may be warranted for contamination issues within 500 feet of the dewatering area.

During construction, if abnormal conditions are encountered or exposed indicating the presence of contaminated materials, these contamination areas should be managed in accordance with FDOT

Specification 120-1.2 Unidentified Areas of Contamination or similar guidelines the County may have in place.

3. DESIGN CONTROLS AND CRITERIA

3.1 Design Criteria

Design criteria were developed for the proposed multimodal transportation improvements based on the

5. PRELIMINARY DESIGN ANALYSIS

5.1 Typical Sections

Refer to Section 4 for a discussion and graphical representation of the No Build and Build typical sections.

Two main alternatives were evaluated for the improvement of the Anclote Road corridor. These alternatives are as follows and shown in Appendices A through D.

• No Build: This alternative involves keeping the two-lane rural roadway section along the project limits and non-continuous sidewalks at various locations.

• Alternative 1 (Phase Areas 1 and 2 and Portion of Phase Area 3): This alternative entails constructing two 11-foot lanes, a 10-foot-wide shared-use path, and a 5-foot sidewalk where feasible.

• Alternative 2 (Phase Areas 1 and 2 and Portion of Phase Area 3): This alternative entails constructing two 11-foot lanes, a 4-foot paved shoulder as an on-street bike lane, and 5-foot sidewalks.

• Alternative 1 (Phase 3): This alternative entails constructing two 11-foot lanes, Type F curb, and a 6 to 8-foot sidewalk from Anclote Boulevard to approximately 290 feet south of Wacassassa

Street.

• Alternative 2 (Phase 3): This alternative entails constructing two 10-foot lanes, Type F curb, 4-foot bike lanes, and a 6-foot sidewalk from Anclote Boulevard to approximately 290 feet south of

Wacassassa Street.

5.2 Bicycle and Pedestrian Accommodations

All alternatives except Alternative 1 (Phase 3) offer cyclists a seamless route on the shared-use path, allowing them to bike from Alternate US 19 to Anclote Boulevard without interruption. Due to the constrained 40-foot wide right-of-way in Phase Area 3, only a wider sidewalk is possible for Alternative 1

(Phase 3). In this segment, the bicyclist can use the sidewalk or share the roadway due to no dedicated bike lanes. A sidewalk is proposed along Savannah Avenue and Brady Road to the work release center.

Pedestrians can use the shared-use path or sidewalk, providing continuous connectivity from Alternate

US 19 to Anclote Boulevard.

5.3 Right-of-Way Requirements

The proposed improvements will have potential right-of-way land acquisition for offsite facilities to meet roadway standards, floodplain compensation and water quality requirements. The existing right-of-way within the project limits varies from a width of 40 feet to 73 feet. Refer to Figure 29 and Appendix N for additional right-of-way and offsite pond requirements and probable costs. Table 7 summarizes the potential right-of-way land acquisition requirements and probable costs for the project improvements.

Note: Includes estimated property cost only.

5.4 Drainage Analysis for Treatment and Attenuation

Rule 62-330.051(4)(c) of the Southwest Florida Water Management District (SWFWMD) regulations exempts the proposed shared-use path, sidewalk addition, and milling/resurfacing. These improvements are expected to meet the criteria outlined in Rule 62-330.451, eliminating the need for formal peak rate attenuation or formal water quality treatment.

The Pinellas County Stormwater Manual 2021, specifically Section 1.5.1 Exemptions, lists the following activities exempt from the manual's performance standards:

• Minor roadway safety construction, alteration, or maintenance, including road widening and shoulder paving that does not…
