Swimming pool requirements and placement. All swimming pools, spas, and saunas shall comply with the following requirements: (A) Application for a permit to construct a swimming pool, spa, or sauna must be submitted to the building official. The structural plans must be approved by the building official prior to the issuance of a permit and the beginning of construction and/or excavation. A drainage plan prepared by a registered professional engineer will be required unless the city staff determines that due to the size, method of construction, location, or other characteristics of the proposed swimming pool, spa, or sauna, a drainage plan is unnecessary under the circumstances. (B) Swimming pools, spas, and saunas and supporting electrical and mechanical equipment may be located in either the side or rear yard and shall be at least five feet from the property line. (C) Swimming pool, spa, and sauna construction must meet all requirements of the codes adopted by the City of Tybee Island. (D) Once a swimming pool, spa, or sauna and its accessories have passed a final inspection it shall be a violation of this ordinance to remove or alter any of the equipment that is required by: the International Residential Code — Appendix G, the International Building Code — Section 3109, the National Electrical Code, and the Georgia State Amendments. Failure to maintain the safety related and/or electrical equipment in good and working order shall constitute a violation of this ordinance. (E) No swimming pools, spas, or saunas shall be placed across, on, or beneath any utility easements nor shall any utility easement be granted which bisects a swimming pool, nor be located within five (5) feet of any marsh buffers as delineated by the Georgia Department of Natural Resources. (F) When a swimming pool, its deck, or other accessory to a swimming pool is proposed for construction on a site that has already been improved, the swimming pool plans and permit application will be reviewed by the City Engineer. (a) If there is an approved drainage plan for the site the City Engineer will review the plans for the swimming pool, deck and accessory structure to ensure that the proposed improvements will not materially affect the drainage of the site. If they will materially affect the drainage of the site the applicant will have to have a drainage plan prepared by a design professional before a permit for the swimming pool, deck or accessory will be issued. (b) If the site was improved without a drainage plan, the City Engineer will review the pool plans and permit application to ensure that the swimming pool, deck or accessory structure will not increase the amount of run -off leaving the site. (G) - 'Any permit for a swimming pool is required to contain a soil and erosion plan for the proposed site prior to the issuance of a permit and commencement of any construction related activity.

My review is limited to drainage issues and land disturbing activities. I have not attempted to duplicate the work of the Planning Commission or City staff with regard to setbacks, density or other zoning or subdivision regulation issues. The following comments are offered. 1) The connection from the existing deck to the proposed pool deck is not shown. The drawing indicates there is a small gap of 1 -2' between them. This is minor and I leave this to other City representatives to address unless I am advised my efforts are needed on this issue. 2) Based on past experience, I anticipate the Contractor will prefer to enlarge the area enclosed by the Sd1- Sediment Barrier. This can be a field adjustment but prior agreement from the City is needed. Neither of these comments requires a plan revision for my concurrence. Contingent on these two comments and within the scope of my design review, to the best of my knowledge and belief, it is my opinion that this drainage plan should meet the requirements of the Land Development Code of the City of Tybee Island. Any recommendations do not relieve the project of the requirement to obtain any other required permits, approvals, etc... by any other governmental body or authority having jurisdiction over any portion of this project Please contact me if you have any questions on this matter.

The proposed project will be the demolition of existing features and the construction of a new pool. The total site is approximately 0.50 acres (as per SAGIS) with the new project being approximately 0.03 acres disturbed. Detention will not be required for this project. The soils in this area have been classified by the Soil Conservation Service as being Cuc ( Chipley Urban Land Complex ). PRE DEVELOPMENT SITE CONDITIONS The existing site consists of several drainage areas but for the purpose of this report, only the drainage area that contains the pool is being considered. The existing drainage area consists of 0.21 acres and drains predominantly to the eastern side of the site. POST DEVELOPMENT SITE CONDITIONS The proposed drainage area is the same in size and pattern from the existing drainage area. ANALYSIS METHOD The only analysis method used for this project was to calculate the Cw factors of the existing drainage and pool versus that of the new drainage area and pool. The new Cw factor is less than the existing because the pool deck is being changed from concrete to pavers. Due to this decrease in the Cw factor, the run -off for the new pool will be less than the existing.

The soil surveys that comprise your AOl were mapped at 1:20,000. Warning: Soil Map may not be valid at this scale. Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and accuracy of soil line placement. The maps do not show the small areas of contrasting soils that could have been shown at a more detailed scale. Please rely on the bar scale on each map sheet for accurate map measurements.
