Re: Tybee Island Maritime Academy
Zoning Application
Dear Mr. Mayor:
April 2, 2014
At a recent meeting held concerning the application by the Tybee Island Maritime
Academy for the ability to locate two (2) modular classroom units on property belonging to the
Diocese of Savannah and St. Michael's Catholic Parish, it was noted that parking might be an
issue on occasion.
At our Parish Council meeting on Thursday, March 27, 2014, the Parish Council
discussed this issued and a motion and vote was made, and it was agreed that if "overflow"
parking was needed on various occasions by the school such would be permitted in our church
parking lot, as long as said parking did not interfere with our regular church services and events.
I hope this information will help the City in reaching its decision.
Sincerely,
Rev. Thomas J. Peyton
Pastor

Engineering Support, Tybee Island Maritime Academy Expansion
Dear Perb:
Thank you for requesting the professional services of Ball Maritime Group, LLC (BMG). We understand that the project
consists of the following for Tybee Island Maritime Academy (Client): Engineering Design and Permitting for the
development of a 6,000-sf facility on 0.76 -acres on Tybee Island, Georgia (Attachment 1 & 2). The proposed effort will be
conducted under the supervision of a professional engineer with a specialty in industrial and commercial site
development. BMG understands that the Client desires to construct a new modular classroom facility with vehicle and
pedestrian access from the existing facility, additional parking spaces, a dumpster pad, and other ancillary utilities. The
project will require provisions for water, sewer, power, communications, stormwater management, and possibly irrigation.
The standards required by the City of Tybee Island will be used for this design and the approval process required to
obtain a land disturbance permit (and other approvals).
Scope of Services
The following is a brief description of our proposed Scope of Services to be provided:
BMG will conduct a field investigation of the property and review any existing information (e.g.: surveys, plans, drawings,
schematics, public data) to gain familiarity with the layout and existing conditions. After this investigation and a review of
the as -built information, BMG will compile all existing information available and develop the conceptual submittal required
for the Land Disturbance Application to the City of Tybee Island (Planning Commission included). This plan in
consideration with the modular building proposal (Attachment 3) will be used to advance the regulatory strategy for the
facility which will include the following key components: 1) National Pollution Discharge Elimination System (NPDES)
permit program and 2) City of Tybee Island Land Disturbance Activity Permitting. The planning effort provided by the
Client (Justification for classroom size) will act as the baseline for the Basis of Design (BOD) developed and used to
develop the Final Engineering Design. BMG will concurrently advance into the engineering design phase which includes
three components: 1) Drawings, 2) Specifications, and 3) Cost Estimate. The deliverables will be as follows:
A. Basis of Design including Conceptual Plan
B. Final Engineering Design for Regulatory Submittal and Construction (Utility Calculations, Stormwater
Calculations, 100% Drawings, Specifications, Cost Estimate)
C. NPDES Submittals
D. Asbuilt Drawings

To Whom It May Concern,
Tybee Island Maritime Academy (TIMA) is a public charter school under the Savannah Chatham County
Public School System We have grown to 295 students and have expanded to utilize every bit of space available
to us. We expect to increase the number of students even more.
In June, the Principal (Mr. Peter Ulrich) and four teachers attended the All Hands on Deck conference in Norfolk, VA.
The conference featured speakers and panel discussions addressing broad areas of maritime workforce training. The two-
day conference addressed opportunities to enhance and expand maritime training, marine technology, ship building and
repair, as well as port management, workforce training, and education throughout the country.
They were able to collaborate with community and technical colleges, K-12 educators, Maritime Administration
(MARAD), US Coast Guard and industry partners to reach the goal of growing and sustaining a world-class maritime
workforce for the years ahead!
For the 2019-2020 school year we will be adding a Makers class and a Coding Class for our students.
Makers create, tinker with old technology, and invent new things. Maker teachers inspire their students to
dream up their own inventions, experiment, fail and experiment again until they've made something personally
meaningful. Maker education is a combination of hands-on learning and project -based learning.
Coding is essential to help students thrive in a future driven by technology. When you teach coding, you
also teach skills like critical thinking and problem solving.
The City of Tybee along with the YMCA has generously allowed us to use the gym for our physical education
classes. Live Oaks Library System has allowed us to use the library and each child has a library card. We have
had to turn part of our gym/cafeteria into classrooms to accommodate the number of students.
To meet the additional space demand due to enhancing our project based learning into STEAM (Science,
Technology, Engineering, the Arts and Math), the additional numbers of students and the need to take back our
gym/cafeteria in full, TIMA needs to add additional classrooms to our campus.
We propose to add a modular building to the lot north of the gym, which would include 4 classrooms, a large
girls' restroom and boys' restroom. This building will be connected to all utilities, internet services, security and
fire alarm services. This will only increase parking space needs by 4 spaces.
We are presenting our request for approval without engineering, surveying and expensive start up costs to
prevent wasting valuable money without approval to move forward. We assure you that we will meet all
ordinance and code requirements once we are approved to start the work as we did in 2014.
We request approval to move forward to add the structure to our footprint.
Sincerely,
CC uri Perb Fortner

Cc: Lisa Schaaf, jason@ballmaritime.com
Subject: Tybee Island Maritime Academy
After reviewing the preliminary documents in your office last Tuesday, Jason contacted me and we
discussed the design requirements. I now have sufficient detail of a drainage design concept (based
on a current topographic survey) to offer the following comments
1. The Engineer is correct that the CSS spreadsheet and related evaluations and documents are
not required based on the scope of this drainage project. Specifically, water quality and runoff
volume reduction exhibits are not required. However, as I advised Jason Ball in our phone
conversation, peak runoff in any direction will not be allowed above the predevelopment rate
for the Type III, SCS 25 -year, 24-hour storm. (Per Article 16 of the Land Development
Code). In this instance, Lovell Ave discharge appears to be the outfall area of
concern. Concrete surfaces referenced in the notes need to be clearly identified on the plan
and accounted for in a simple drainage report.
2. The Engineer is correct that there does not appear to be a dependency on this project area by
the property of others for drainage conveyance. It
does continue to convey minor yard runoff onto the lot to the east, under the same
ownership. This is not a concern of the reviewer.
3. More detail is needed on the proposed drainage pattern. Documentation is to be provided
showing this. There are no proposed elevations to show implementation of the proposed
drainage pattern referenced in phone conversation and indicated by flow arrows. The
exhibit/plan needs to clearly delineate between existing and proposed elevations, contours,
and flow direction arrows.
4. There were no dimensions shown on the lot lines.
5. The ADA ramp indicates a connecting ADA pathway, but no detail is given on the
pathway. The total parking count for this facility with the number of ADA parking spaces
(including van accessible should be noted on the plan or in other documentation acceptable to
the City.
6. If the parking is to be unpaved, the method of stabilization needs to be clarified.
7. With flow continuing beneath the building, the method of stabilizing this shaded/covered area
needs to be addressed.
8. No erosion and sedimentation controls were shown.
9. The final plans will require a signed GA PE Seal with supporting drainage calculations.
This is the same criteria that the previous school buildings were reviewed under approximately 5
years ago.
While the list may appear huge, it's not. The existing topo and the design concept presented verify
that there are no significant obstacles to completion of a full drainage design. There's not a huge
effort needed to provide the additional detail needed prior to the construction phase. I anticipate the
Engineer can address these comments well before the end of the public meetings.

Mr. George Shaw
Planning & Zoning Manager
City of Tybee Island
P.O. Box 2749
Tybee Island, GA 31328
re: PN 19-1000 — TI MA Expansion: Stormwater Management Plan
Dear George:
This submittal has been assembled based on our understanding of the project, the requirements for stormwater
management discussed with Mr. Downer Davis, PE, and the previous responses from the Planning Commission. In order
to meet the requirements for approval, it is our understanding that the proposed site must not increase the impervious
coverage from the pre -developed site and the site must detain the post development stormwater run-off below water is
released from the site currently. Please refer to the submitted plans for information complimentary to this narrative. The
engineering drawings for the project will reflect the actual construction activities proposed below (Attachment D).
Pre -development and Post Development Considerations
The project site is considered to be the property boundaries on the north and east, the north edge of the existing gym, and
the edge of pavement along Lovell Avenue. This is approximately 0.25 -acres. The pre -development impervious coverage
on the site is 0.21 -acres. The post development conditions will include additional impervious area to accommodate the
garbage dumpster pad, but impervious area will be reduced in the existing parking areas along Lovell Avenue to balance
out the net results. The table below reflects this change. The modular building does not count as an increase in
impervious area due to it being elevated and the footprint being used as a gravel infiltration best management practice.
Unpaved parking is currently provided along Lovell Avenue and will remain that way for this project.

PN 19-1000: TIMA Expansion Page 2
BMG/GS
Based on a topographic survey performed for the site in July 2019 by Gammon Surveying (Attachment A), there is no run-
off through the site from the adjacent properties. The run-off generated from the impervious surface of the modular
building rooftop in a 25 -yr 24 -hr storm event will be pitched to eastern side into a 6" gutter. The run-off will be conveyed
downward through four 4"x4" downspouts to the ground level into energy dissipators. The run-off will then drain from the
east to the west over the re -graded site, traveling through the gravel base installed beneath the footprint of the building. It
is anticipated that no drainage will leave the site under these design conditions.
The volume of run-off generated from the roof top will be approximately 114 -cubic feet using a 25 -year 24-hour storm
event with an intensity of 0.33 -inches (from GSMM Volume 2 for Savannah). A gutter sizing spreadsheet was used to
confirm the minimum number of downspouts and gutter size required (Attachment B). This will be used for the design of
the modular building. The volume of storage provided by the 6" gravel base beneath the building is approximately 870.4 -
cubic feet using a porosity factor of 0.4 for gravel. Since the soils are Group A (Attachment C — Web Soil Survey), it
assumed that the infiltration rate is 6"/hour or 2,176 -cubic feet per hour. This means the infiltration practice will drain in
approximately 30 -minutes or less. The site will effectively accommodate the 25 -year 24-hour storm event onsite without
contributing to any conditions downstream of the site.
We look forward to any questions you may have after reviewing this submittal. Please contact our office if you have any
questions, concerns, or desire additional information.

1
ABC = Inputs XYZ = Results
Determine the rainfall intensity for a 5 -minute duration storm for a given return period(2).
Frequency = 25 years
Amount, P = 0.33 inches
2
Compute the capacity of the selected gutter size.
Gutter dimensions:
tw = 6.0 in
bw = 4.600 in
d = 4.600 in
fb = 0.5 in
Qg = 0.01184 x Ag x r^0.67
Qg = 0.35 cfs, capacity of gutter
Ag = 21.42 sq in, cross-sectional area of gutter
wp = 12.99 in, wetted perimeter of gutter
r = 1.65 in, Ag/wp, hydraulic radius
3
4
Compute the capacity of the selected downspout.
Downspout dimensions:
W = 4.000 in
L = 4.000 in
Qd = 0.010457 x Ad x h"0.5
Qd = 0.34 cfs, capacity of one downspout
Ad = 16.00 sq in, cross sectional area of downspout
h = 4.10 in, head (generally the depth of the gutter minus 0.5 in)
Comparing the above calculated capacities, Qg and Qd, Downspout capacity controls
5
Determine roof area that can be served per downspout.
The area of a roof that can be served by a gutter and downspout system is controlled by either capacity of the gutter (channel
flow) or bv the capacity of the downs out orifice flow as shown in 2 and 3 above.
Q = 0.34 cfs, capacity of single downspout system (smaller of Qg and Qd)
Ar = 3,696 sq -ft of roof area that can be served by this single downspout with P =
0.33 inches/ 5 min.
6
Determine the number of downspouts necessary to control the water from the entire roof area.
In a multiple downspout system, the number of downspouts is determiend by dividing the entire roof area draining into the gutter,
Atotal, by the roof area that can be served by one downspout, Ar, as follows:
Total roof area to be served by this gutter system, Atotal = roof length x roof width.
Roof Dimensions
T
�"
6" K SI }.fit
a
rr•
length = 64 ft
width = 68 ft
Atotal = 4,352 Sf
Number of downspouts, Nd = Atotal / Ar = 1.18
so use 2.00
Total downspout(s) capacity = 0.68 cfs
= 304 GPM
(1) Roof Runoff Management (AWMFH, Chapter 10, pgs. 10-1
thru 10-3)
(2) As an alternative for the Pacific Islands, multiply the amount
for a 15 -minute duration storm by 0.6 for a close approximation
of the amount for a 5 -minute storm.
