Introduction

Pinellas County maintains the closed Toytown Landfill and as part of this effort maintains the site stormwater and groundwater monitoring system. The site includes stormwater swales and a pond with a pond water level gauge that is read manually to track pond levels. The pond depth varies throughout the year during the dry season and wet season. The County wishes to replace the staff gauge at the stormwater pond and also construct a dock to be able to read and clean a new staff gauge and collect pond water samples as needed. This memo will review the

County minimum requirements for a dock and evaluate the different dock options for the County’s review and selection.

Approach

For this, we determined County requirements, reviewed pond data for range of depths, and evaluated up to four different dock options. Data collected with the existing staff gauge cannot read pond water levels if below an elevation of 2.15 feet. The 10-year average pond water level elevation is 3.38 feet and a maximum water level elevation of 4.23 feet was reached in 2016. Based on data collected, the pond water level elevation varies by 0.2 feet to 1 foot within a year but likely varies even more due to lack of readings below the water level elevation of

2.15 feet. As a result of the variance in pond water level and increased deposit of sediment over the years, the existing staff gauge is tilted and not secured. Pinellas County wants to install and anchor a new staff gauge and a new dock that extends out into the pond for staff to access and clean the gauge and collect water samples. Two locations of the staff gauge were considered: one by the shore near the current staff gauge location and one towards the middle of the pond.

The advantages of installing the staff gauge and dock towards the middle of the pond include:

• Less impact from varying water levels even during the dry season and allowing for staff gauge readings at low water levels as well, when the near shore mounted staff gauge is out of the water.

• Less damage to staff gauge from near shore maintenance activities.

• Less steep slope of gangway to the dock, mitigating concerns of steep gangway from some vendors.

• Less wear and tear to dock as it will lie more evenly during the dry season.

Toytown Landfill Staff Gauge and Dock Option Review

Pinellas County Solid Waste

February 27, 2024

However, the main disadvantage of installing the staff gauge towards the middle of the pond is higher costs due to a longer gangway and larger dock needed to support the gangway as well as feasibility dependent on actual depth of pond at proposed location.

Various vendors were contacted to determine and develop alternative options for a dock at both proposed locations. Capital costs, maintenance required, and useful life for each option as well as some notable advantages and disadvantages are presented below.

Design Criteria

The criteria for the staff gauge and dock include:

• Material of construction – wood and steel are not preferable unless proven to last 30 years. Prefer corrosion resistant materials.

• Capacity – should be able to hold one to two people at a time, approximate weight minimum capacity of

500 pounds

• Handrails – for safety and comfort

• Additional side grating for prevention of alligators and other wildlife climbing on to dock (optional)

• Maintenance – Low maintenance requirements

• Lifespan – 30 years

• Staff gauge – 1-inch incremental elevation measurements with a precision of 0.01 feet up to 8 feet

Other considerations:

• Material and Installation Costs

• Material Lead Time

• Construction of concrete pad for anchoring gangway and dock on the bank

• Clearing vegetation around staff gauge prior to installation of dock and gangway for ease of access

Staff Gauge and Dock Near Shore

In addition to the design criteria listed above, the following gangway and dock size were considered for a shore mounted staff gauge.

• Gangway/walkway: a 10-foot aluminum gangway that extends from the pond bank near the existing weir down the slope to the dock

• Dock Size: a minimum 10-foot-long dock (extends from gangway into the pond a few feet past the new staff gauge)

Staff Gauge Installation

Arcadis and the County discussed different shore-mounted staff gauge mounting methods and locations as well as considering other staff gauge configurations used by the County and their performance. After collaboration, it was determined that the staff gauge will be anchored by a 4x1 inch aluminum channel from the existing concrete weir and further secured on a 4x4 inch aluminum support beam anchored in concrete set into the pond bottom.

There will be an additional 2x2 inch aluminum post between the weir and the staff gauge to stabilize the long arm span. This is a similar configuration to several staff gauges in use at the Bridgeway Acres Site. The detailed vendor cost estimate for materials is included in Appendix A.

Metal Supermarkets Price

Aluminum Square tube and Channel $315

Miscellaneous $100

8’x4.875” aluminum staff gauge (oregonrule.com) $120

Total $535

The staff gauge near the shore was installed by Arcadis staff on February 5th and 6th of 2024. Photos of the newly installed staff gauge are shown below.

TTLF Staff Gauge and Platform Options Review Memo Final - Client Issue 2-27-24

Staff Gauge and Dock Towards Middle of Pond

In addition to the design criteria listed above, the following gangway and dock size were considered for a staff gauge anchored towards the middle of the pond, which would be approximately 50 feet away from the pond bank.

• Gangway/walkway – a 50-foot aluminum gangway that extends from the pond bank near the existing weir structure down the slope to the dock

• Dock Size – recommended size by vendor in order to support a longer gangway. May vary.

Staff Gauge Installation

An 8-foot staff gauge can be mounted on 2-inch x15-foot aluminum post that is driven into the pond bottom by at least 5 feet to anchor it securely. The Staff gauge will be mounted on a 2-inch x 6-inch pressure treated wood plank and attached to the aluminum post with U-bolts. This design allows for easy adjustments during surveying and easier maintenance. Feasibility of this option is also dependent on actual depth of pond at proposed location.

Market Price

Aluminum post $150

Pressure treated wood plank $11

304 SS U-bolts with mounting plates (4) $9/each ($36)

8 foot x 4.875 inch aluminum staff gauge

(oregonrule.com) $118

Total $315

Dock Options Reviewed

Three dock options were considered:

1. Fixed dock – composite decking

2. Prefabricated floating dock of composite material

3. Prefabricated floating dock of aluminum material

Feasibility of this option is also dependent on actual depth of pond at proposed location, as all options will be anchored at the proposed location and poles or piles will need to be of adequate length. Vendor estimates for a

50-foot gangway for options 1 and 2 have not been received at this time but will be included in the final technical memo submittal. The cost will be higher than the near shore options as more materials and potentially more complex construction due to location of anchor poles are piles will be required.

Option 1: Fixed dock – composite decking

Dock contractors such as Gulf and Bay Dockworks provided a quote based on the design criteria and considerations listed above. A 50-foot fixed walkway and 12-foot x 12-foot main fixed dock of composite decking was quoted for. The detailed quotes provided can be found in Appendix A.

Summary and Conclusion

While the original scope of work included reviewing four options for a gangway and dock to access a shore mounted staff gauge, Arcadis also reviewed options if the staff gauge were to be installed in the middle of the pond. The final location of the staff gauge will be decided based upon the County’s review and consideration.

Regardless of the staff gauge location, the floating dock options will likely be most functional for staff gauge reading, cleaning, and pond sampling as they will rise or fall with the pond water level. The floating dock options are also most cost effective and have a longer general lifespan than the fixed dock option.

For a shore mounted staff gauge, of the floating dock options, the modular plastic floating dock (Option 4) is the lowest cost option, even for a larger dock. The best durability option is the prefabricated floating dock provided by

Trident Marine Construction or Accu Docks (Options 2 or 3). The cost-effective option with most of the desired features is option 2, prefabricated floating dock of composite material, as it includes aluminum railing on 3 sides of the dock to deter wildlife from loitering on the dock. But it must also be noted that this option did not include installation costs. Installation costs have been requested but has not yet been received. Based on other quotes received, the estimated installation cost could be around $700 - $1200, resulting in an estimated total for option 2 of about $9,900.

For a staff gauge installed towards the middle of the pond, further review of the options is required as vendor quotes are received, and this option is discussed further with the County to ensure it meets their needs and potential site limitations.

Based on comments received from the County after reviewing the draft memo, the County has decided to move forward with a shore mounted staff gauge anchored by an aluminum channel from the existing concrete weir and further secured by an aluminum support beam anchored in concrete set into the pond bottom. The County has decided to move forward with a modular floating dock such as EZ Dock with a 6-foot x 10-foot floating dock for increased stability.

The next steps include installing the shore mounted staff gauge as described above and purchasing a modular floating dock through the County Purchasing Department.
