Attached is the inforrration on the Winter Springs Cormerce Center
as was I:eqlERted by the Cbrrmission at the I:ecerrber 13, 1985 neeting.
Staff revie~d the project on I:ecember 24,1985 and recomrended approval
subject to the City Engineers neno of January 10, 1986. Also attached
is a copy of the IIEIID. IXe to the unique problems of the project in
reguard to the changing of an engineer in the middle of a project, the
the plans as revieved will need to be completely revised. 'Ib that end
attached is a letter from the project engineer and a subsequent letter
from the past project engineer.
The City Attorney has drawn up the warrenty deed which has been executed
by Mr. Dittrrer and returned to the city, thus forrrally deeding the 15
feet along the Florida ~r Corporation Easenent to the Wild Vbxl HOA.
The resicEnts are now in possession of the association. 'Ihe deed will be
recorded this week.
Mr. Dittrrer has also filed with the city for the vacation of that
portion of Wild Wood Dri ve ~st of Tanglewood lbad. This does need to
be a joint application between Mr. Dittrrer and the Wild Vbxl Association
and has yet to be reviewed by staff. No problems are anticipated as
long as both Parties agree. The vacation will require a public hearing
as this is public land.
The revised plan is anticipated to be presented to the city in the :ooxt
couple of weeks. Florida Paver Cbrporatian is in the process of developing
a lighting plan to assure all services will be tmdergrotmd, and upon
the City Attorney approving the deed restrictions the project is ready
for approval.

Re: Winter Springs Commerce Center
Final Engineering Review Comments
Dear Mr. Woods:
Your final engineering plan for the Winter Springs Commerce Center
has been received and reviewed. The following discrepancies have been
noted and need clarification and correction.
1. What is the 100 year flood elevation at the site?
e
2. On sheet 2 of 3 of the engineering drawings, the utility
easement in phase II should be fifteen (15) feet wide as per
the Land Development Code, Section 14-97.
3. On sheet 2 of 3 of the engineering drawings, there is no catch
basin shown at the southeast quadrant of the road circle to
receive the stormwater into the storm swale or drainage ditch.
Please clarify.
4. Please provide detail drawings on the type "c" inlets.
5. On' sheet 3 of 3 of the engineering drawings, Sections A-A, B-B,
C-C, and D-D show a design slope of 3:1. FDER Rule 17-25 and the
Land Development Code Section 122 require a 4:1 slope or shallower
to the bottom elevation of the pond. Please provide this adjustment.
This adjustment may affect the volumetric design of the ponds to
accommodate the peak discharge for a 24 hour 25 year storm event.
If it is desired to retain the present slopes at the retention ponds,
then it will be necessary to install fences.
6. On sheet 3 of 3 of the engineering drawings; System Pop-Off Structure;
if reading the drawing correctly the invert of the overflow pipe is
37.92; therefore, what height of water represents the retention of
the first One-Half (~) of water?

7. Please provide a copy of the DER stormwater permit for this project
along with a copy of the DER permit for the drinking water distribu-
tion system.
8. On sheet 3 of 3 of the engineering drawings, it is noted that the
ditch block is constructed of field stones. Are the stones
permeable? If it is highly permeable, then water would move through
it with ease, thus reducing its effectiveness as a block. Please
explain.
9. It was noted on sheet 3 of 3 of the plans, there was a statement that
Final Development/Preliminary Engineering was submitted in January
1985. Bear in mind that the engineering submitted at that time was
preliminary only. The final engineering is now under review. Ther~fore,
the engineering submitted with this final engineering developed by Land
Engineering Company cannot be accepted, since it is not signed, sealed
and dated by the engineer. Please have this engineering signed, sealed
and dated.
10. Is it correct to state that each lot will have septic tanks? Please
clarify.
e
11. On sheet 3 of 10 of Land Engineering Company drawings, the entrance to
the project has a corner radius of 30 feet. It is recommended that a
fifty (50) ft. radius be employed to accommodate fire trucks and,
potentially other large trucks that may enter the complex.
12. On sheet 4 of 10 Land Engineering Company drawing, Sections A-A and
B-B, the width of the street is 18 feet (9' and 9'). The Land
Development Code does not allow streets to be less than 10 feet wide
per lane. Sections 14-126 and 14-95. Please make the necessary adjust-
ments.
13. If the Land Engineering Company plans are to be submitted as part of
the final engineering, whose storm water, control structure and under-
drain design is to prevail? Please clarify. Your plans and Land
Engineering Company plans were both submitted covering this area.
14. On sheet 8 of 10 of the Land Engi?eering Company drawings, standard
paving and drainage details, the typical street section and entrance
section, it is noted Type III asphalt concrete is to be used. The Land
Development Code, Section 14-115 requires Type I asphalt concrete to be
used. Please make the necessary adjustments.
15. On sheet 8 of 10 of the Land Engineering Company drawings, standard
paving and drainage details, the curb inlet Type B-or-R shows one 8
inch support dowell. This is contrary to the Land Development Code,
e

Section 14-126 which requires two 6 inch support dowe11s. Please
make the necessary adjustments.
16. On sheet 10 of 10 of the Land Engineering Company drawings, standard
water detail, the fire hydrant installation, please callout the
installation of a thrust block at the elbow going to the fire hydrant.
17. In the preamble of the drainage calculations, there is mention of
retention areas for individual lots. Where does the individual
retention areas for the lots appear on the engineering drawings?
Please designate. The retention volumes are noted for each lot in
your commentary but nothing is noted as to where the water is to be
retained.
e
18. It is noted in your commentary that individual lots will have retention
areas that will store the difference between pre - and post - develop-
ment runoff from a ten (10) year, twenty-four (24) hour design storm.
It is necessary to calculate this retention for a 25 year, 24 hour
storm event. This is required in the "Applicant's Handbook, Manage-
ment and Storage of Surface Waters, St. Johns Water Management District"
Section 10.3, Peaks Discharge and the Land Development Code, Section
14-122. Therefore, your retention calculations will have to be re-done
and the" retention ponds possibly reconfigured.
19. In the commentary, step 4, is it correct to assume the stormwater from
lots 15, 16, 17 and 18 will flow onto Dittmer Drive to the ditch on the
circle?
20. In your commentary, step 8; is the conveyance system to be used, desig-
nated or classified as a retention pond?
21. In appendix A, Calculations, page 1 of 7, the calculated required
storage in individual lots has been designed for 10 year, 24 hours.
This is not acceptable. The calculations must be recalculated for 25
years, 24 hour storm event (see item 18).
22. In appendix A, Calculations, page 2 of 7, how were the concentration
times derived?
23. In appendix A, Calculations, page 30f 7, the value of 3.592 obtained
by multiplying 3.367 (1.07 ft.) is incorrect in the Cipolletti Equation.
Please make the correction and recalculate.
24. Please show the calculations in deriving the discharge and storage
using the Cipolletti Equation.
25. Please specify the volume that is to be retained in each retention area
and the calculations of how it was derived.

26. On page 3 of 7, Appendix A Calculations, you determined discharge
calculations for the earthen weir structure for individual lot
retention areas; yet from the drawings, lot 2, 12, 16, 11, 17, 15,
13, 14, and 18 do not appear to have any influence on the earthen
weir structure by virtue of the stormwater from these lots goes in
another direction because of their location. Please explain and
make the necessary adjustments.
27. On page 4 of 7, Appendix A Calculations, the discharge calculations
for ditch block in the Main Drainage the stage of 50 has a storage of
.15 AC-ft. (6534 cubic feet). The printout, "Route North Dittmer
Drive Discharge Over Ditch Block" has a stored volume of 0.16 acre-
feet (6969.6 cubic feet). Please explain the discrepancy and make
the necessary adjustments.
28. On page 4 of 7, Appendix A Calculations, the discharge calculations
for system pop-off structure to Rustic Woods Storm Sewer System, the
stage 40.95 has a storage of .42 acre-feet (18295.2 cubic feet). The
printout "Route Final Hydrograph Through System Pop-Off Structure" has
a stored volume of 0.82 acre-feet (35719.2 cubic feet). Please explain
the discrepancy and make the necessary adjustments.
e
29. On page 5 of ~, Appendix A Calculations, the velocity of the swa1e,
section D-D, there was noted a discrepancy in the calculation of 7.78
feet. It was determined to be 7.82 feet. Please make the necessary
adjustments.
30. On 6 of 7, Appendix A Calculations, how was the volume below weir invert
10,-890 C.F. derived? Please show calculations.
31. Please provide a summary of stormwater storage for the 25 year, 24
hour stormwater event, the designed storage capacity of all retention
areas and the dimensions of these retention areas (ponds).
32. In the Universal Engineering Testing Company report dated February 19,
1985, Report Number 8113, Test borings 3 and 4 do not denote the ground
water elevations. Please provide the informat~on as to where these
levels are located.
33. On page 2 of 8 of the Universal Engineering Testing Company report number
8113, it is mentioned Type III asphalt concrete is to be used. The Land
Development Code, Section 14-115 specifies Type I asphalt concrete.
Please make the appropriate adjustments.
34. On page 3 of 8 of the Universal Engineering Testing Company report
number 8113, there is mention that the stormwater will flow laterally
through surficial sand. In which direction is this flow to occur?
