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. . .~ e ..~~1.."'..:1.1 .;~ ,"INTE.q '. ,;-cj ... ~', :"'tu'~ '\:' III 0 . 1'(; ~ . y. ,,,.... , , .

CITY OF WINTER SPRINGS, FLORIDA 1126 STATE ROAD 434 WINTER SPRINGS, FLORIDA 32708 Telephone (305) 327.1800 January 10, 1986 Mr. W. Ronald Woods, P.E. Woods Engineering Consulting, Inc. 725-E West State Road 434 Longwood, Florida 32750 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? e e Mr. W. Ronald Woods, P.E. January 10, 1986 Page 2 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 - Mr. W. Ronald Woods, P.E. January 10, 1986 Page 3 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. e - Mr. W. Ronald Woods, P.E. January 10, 1986 Page 4 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? e If you have any questions, please contact this office. - e e "/ Mr. W. Ronald Woods, P.E.
