1.0 GENERAL PROJECT INFORMATION

1.1 LOCATION, EXISTING CONDITIONS & PROPOSED PERMIT MODIFICATIONS

The East Naples Mine is comprised of Phase 1 (Permit No. 59.814 – 1) and Phase 2 (Permit No. 59.814 – 2) which are located in parts of Sections 21 and 22, T49 South, R 27 East. Mining began in Phase 1 in 2003 and continues. Mining has not commenced in Phase 2 yet.

Since Phases 1 and 2 have the same ownership, it is proposed that the shared boundary between the two phases be excavated. Setbacks from the wetlands in the northeast and southeast corners of Phase 1 will remain as required. The depth of excavation in the respective Phases will remain as previously permitted for each phase – for Phase 1 see Section F on drawing 936-13 and for Phase 2 see Section E on drawing 4459-8.

2.0 TRIP CALCULATIONS

2.1 ESTIMATION OF TOTAL TRIP COUNT

Approximate volume to be excavated in Phase 1 (Tract 21) = 284,085 CY Approximate volume to be excavated in Phase 2 (Tract 15) = 506,337 CY

Volume moved per truck per trip = 18 CY

𝑃ℎ𝑎𝑠𝑒 2 = 28,130 𝑇𝑟𝑖𝑝𝑠 𝑅𝑒𝑞𝑢𝑖𝑟𝑒𝑑

156 𝑇𝑟𝑖𝑝𝑠𝐷𝑎𝑦≈ 180 𝑑𝑎𝑦𝑠

Phase 1 & 2 = 102 days + 180 days = 282 days

282 days/5 days/week = 56.4 weeks = 14 months

3.0 SIGNIFICANCE ON IMPACTED LINKS

3.1 AFFECTED LINKS

The haul route includes (1) – 5th Street to Golden Gate Boulevard, (2) – Golden Gate Boulevard from Collier Boulevard to DeSoto Boulevard, (3) Collier Boulevard from Vanderbilt Beach Road to Pine Ridge Road, and (4) - Wilson Boulevard from Golden Gate Boulevard to Immokalee Road.

The estimated 14 months of hauling will contribute approximately 156 average daily trips with trip distributions as shown on the attached Haul Road Map.

3.2 TEMPORARY IMPACT TO AFFECTED LINKS

Information provided in Attachment “F” of the Collier County 2017 Annual Update and Inventory Report was used to analyze the impact of the trips on the affected links.

The estimated trips attributed to the hauling operation will contribute less than 1% of total peak-hour peak-direction volume for each affected link. These trips are already part of the existing

traffic volumes. The proposed excavation removal will not have a significant or adverse impact on the surrounding road network.

4.0 EXISTING ROAD CONDITIONS

4.1 OVERVIEW

An examination of the Collier County portion of the haul route was performed on June 12, 2018. The general condition the roadways is good. There are no significant defects in asphalt, curbs, striping or drainage structures to report. The roadway system was observed to have normal wear and tear including chipped curb, weathered thermos-plastic striping and minor asphalt defects. A Collier County FY2018 Capacity Enhancement Project states that Golden Gate Boulevard will be under construction from Wilson Boulevard to DeSoto Boulevard. At present time, Golden Gate Boulevard from Wilson Boulevard to 18th Street has been expanded to a 4-lane road. Also, a Collier County FY2018 Capacity Enhancement Project has Collier Boulevard, from Golden Gate Boulevard to Green Boulevard expanding into a 6-lane road. As of June 2018, all construction along Collier Boulevard has been completed. If necessary, the mine owner will conduct a review of existing roadway infrastructure with Road Maintenance to determine any concerns due to hauling of excavation material. This review will identify any areas of concern. Criteria to be considered include:

1. Current pavement rating; 2. Field review/survey; 3. Current scheduled repairs; 4. Repairs to reduce the likelihood of accelerated damage under the proposed haul trips.
