Page 2 Response to Comments Application# 2. I will need clarity on the size of the palms to be planted since that was not identified in the new plans. Response: Adjusted landscape schedule for palms at 12" min. caliper. 3. There is now proposed removal in the right-of-way which is calculated at a different rate so those are on a separate sheet. Response: Separated mitigation table and summary for right-of-way. 4. While you are well short on mitigation across all types of trees, it should be noted that you must replace at least 25% of legacy trees removed with new legacy tree species. You are still short of this requirement. Response: Preserved trees are greater than 3" diameter to receive mitigation credit Please see sheet M-1 for preserved trees. Adjusted note and calculations for required mitigation inches and 25% of legacy trees.

PRE-DEVELOPMENT SITE INFORMATION This 0.9 acre piece was previously developed and was occupied by one single family home as well as a triplex residential unit until 2016. The property drained to the public infrastructure along Ahern Street and East Coast Drive. Due to its proximity to the ocean, we have noted through site visits that the soil is very sandy with a low groundwater table. POST-DEVELOPMENT SITE INFORMATION This project will bring 4 townhome buildings with pervious parking and paver courtyards. All stormwater runoff will be collected and taken to two dry swales along the northside of the project. The ponds have been sized to provide treatment to dry retention standards of the F.A.C. and attenuate the 25 year 24 hour and mean annual storm events. Due to the total size of the project (0.90 acres) and with an impervious area less than 2 acres, this permit is being processes as a 10/2 Self Certification through the FDEP website. Maintenance The applicant will be responsible for all maintenance.

S � PROJECT DESCRIPTION Ahern Townhomes Atlantic Beach, Florida The project involves the construction of 4 buildings with 3 townhome units with associated infrastructure at the intersection of Ahern Street and East Coast Drive. PRE-DEVELOPMENT SITE INFORMATION This 0.9 acre piece was previously developed and was occupied by one single family home as well as a triplex residential unit until 2016. The property drained to the public infrastructure along Ahern Street and East Coast Drive. Due to its proximity to the ocean, we have noted through site visits that the soil is very sandy with a low groundwater table. POST-DEVELOPMENT SITE INFORMATION 1 This project will bring 4 townhome buildings with pervious parking and paver courtyards. All stormwater runoff will be collected and taken to two dry swales along the northside of the project. The ponds have been sized to provide treatment to dry retention standards of the F.A.C. and attenuate the 25 year 24 hour and mean annual storm events. Due to the total size of the project (0.90 acres) and with an impervious area less than 2 acres, this permit is being processes as a 10/2 Self Certification through the FDEP website. Maintenance The applicant will be responsible for all maintenance. i T ATTACHMENT A Figures nrrr C kit `J� C. 1 in O 17th St *. u -• o r 1 > C f n _, a ::-Z n Dutton Island Rd W .,h 16th St Dudley St Q. rrY Club Ln t 15th 5 0 Lewis St o r, ora St lath St ^ Robert St fO Q t. o tn rn Edgar St a s 13th St a c o rn 7; Jackson Rd.' 12th Stc eu.

Reeves City of Atlantic Beach 800 Seminole Road Atlantic Beach, FL 32233 Reference: Ahern Town Homes @ Atlantic Beach Application # Prosser# 116073.01 Dear Mr. Reeves, We are enclosing herewith site development/construction plans review of the Ahern Town Homes @ Atlantic Beach submittal. Enclosed you will find: • 4 Sets of Revised Signed and Sealed Plans • Comment Responses Below Public Works Correction Items 1: • Please confirm if these will all be 34" meters or if you are planning to upsize the townhome meter sizes. You essentially have water and sewer System Development Charge credit for six 3/" services (meters), for a total credit of $31,140 and a Meter Connection Charge credit of$1,110. Response: 3/4" meter confirmed, updated callout on plan, see sht. C5.0. • Also, the JEA Plate W-1 is missing from you detail sheet. I will add a comment on the permit review sheet for that, but wanted to let you know. Response: JEA Plate W-1 detail added; see Sht. C6.2. Planning Review Landscape Correction Comments 1. Several trees have already been removed that were not in my initial calculations for the buildable area. I called those out in Red. My original calculations are in Blue. The new requests are in Green. Response: Updated mitigation summary to reflect the original permit, calculations that were not shown previously removed 6/3/17, and the proposed additional inches. Page 2 Response to Comments Application# 2. I will need clarity on the size of the palms to be planted since that was not identified in the new plans. Response: Adjusted landscape schedule for palms at 12" min. caliper. 3. There is now proposed removal in the right-of-way which is calculated at a different rate so those are on a separate sheet. Response: Separated mitigation table and summary for right-of-way. 4. While you are well short on mitigation across all types of trees, it should be noted that you must replace at least 25% of legacy trees removed with new legacy tree species. You are still short of this requirement. Response: Preserved trees are greater than 3" diameter to receive mitigation credit Please see sheet M-1 for preserved trees. Adjusted note and calculations for required mitigation inches and 25% of legacy trees. If you have any further questions or require any additional information, please feel free to contact our office at (904) 739-3655. Sincerely, PF7SrC J. Bradford Davis, P.E.

PROJECT DESCRIPTION Ahern Townhomes Atlantic Beach, Florida The project involves the construction of 4 buildings with 3 townhome units with associated infrastructure at the intersection of Ahern Street and East Coast Drive. PRE-DEVELOPMENT SITE INFORMATION This 0.9 acre piece was previously developed and was occupied by one single family home as well as a triplex residential unit until 2016. The property drained to the public infrastructure along Ahern Street and East Coast Drive. Due to its proximity to the ocean, we have noted through site visits that the soil is very sandy with a low groundwater table. POST-DEVELOPMENT SITE INFORMATION This project will bring 4 townhome buildings with pervious parking and paver courtyards. All stormwater runoff will be collected and taken to two dry swales along the northside of the project. The ponds have been sized to provide treatment to dry retention standards of the F.A.C. and attenuate the 25 year 24 hour and mean annual storm events. Due to the total size of the project (0.90 acres) and with an impervious area less than 2 acres, this permit is being processes as a 10/2 Self Certification through the FDEP website. Maintenance The applicant will be responsible for all maintenance.
