Compliance with Seminole Towne Center Permit No.4-117-0369M2 Dear Rod: Enclosed for .your review is -a General Permit Application Package for.the'above referenced project., The purpose of'.this application is. to. show compliance with an existing Seminole Towne Center Permit No.- 4-117-0369M2. The ACI Income Fund Planned Development in Sanford, Florida was calculated *.as a contributing area to Seminole Towne Center.Pond No. l.in the above referenced SJRWMD permit.- -The ACI Income Fund.P.D.:includes what was referred to as Seminole Towne Center Tract '13 and the. property". This Planned Development includes 'a.total of 5.0236 acres. The following attachments are included -in order to demonstrate that our acreage has been included in Permit No. 4-117-0369M2. 1. , Copy of.letter sent to Mr. Rod Pakzadian for a request for second permit modification. c 2.

As long as the ACI Income Fund P.D. has an impervious percentage.equal to or less than 80 percent of the total site area, it will be in compliance with Permit No. 4-117-0369M2. We have enclosed a set of site plans for your review. As can be seen on Sheet D-2, Site Plan, under landscape areas, the open space provided is 1.057-acres or 21 percent open space. This would equate to 79 percent impervious cover (3.97 acres). This -.site therefore complies with`the individual MSSW permit. We trust that upon your review of the information pro- vided, you will. be able to issue our General Permit. If 'you . have any questions or comments, please do not hesitate to. call.

The purpose of the application is two -fold: 1. To allow for modifications to Stormwater Pond No. 1 to accommodate additional off -site areas; and 2. To provide for off -site mitigation for construction related impacts to on -site wetlands. The following items are enclosed to facilitate your review: 1. MSSW Application (original and 2 copies), including Supplemental Sheet A. 2. Notice of Receipt of Application and attachments thereto (5 copies). 3. Check in the amount of $2000 to cover the permit application/processing fee. 4. Drainage Calculations (3 copies, signed and sealed). 5. Master Drainage Plan -- Exhibit 3 (3 copies, signed and sealed). 6. Stormwater Pond No. 1 Detail Sheet (Sheet 24 of 43) (3 copies, signed and sealed). 7. Legal Description for additional off -site preservation area (2.18 acres) (3 copies). 8. Proposed language concerning Baseline Monitoring/Survey for possible inclusion in the permit "Conditions of Approval" (3 copies). The first aspect of this submittal, i.e., Modifications to Stormwater Pond No. 1, involves modifications that will allow the pond to accommodate stormwater runoff from the off -site Holiday Inn Property" and the "Rife Property," which are contiguous to the Seminole Towne Center Project Boundary. The attached Master Drainage Plan for the Seminole Towne Center Project has been revised to depict the location of the subject properties. Although this application submittal provides for the modification of the Seminole Towne Center Master Drainage Facilities 200 East Rob;nsen Street • Suile 1560 • Orlando. F!crida 32801 • 407.422-8062 - FAX 07 843 ?aJt I Rod Pakzadian October 2, 1995 Page 2 to accommodate the stormwater runoff from the subject off -site properties, it is our understanding that prior to development of either of these properties, separate General Permit Applications for their proposed specific site improvements must be submitted to and approved by SJRWMD. The proposed modifications include lowering the Control Water Level of Pond No. 1 from elevation 27.3 to 26.7 in order to provide the required additional water quality treatment and detention volume, and revising the Outfall Control Structure to effectuate peak stage elevations similar to that previously permitted. Proposed pond modifications also include an adjustment to the pond's west maintenance berm elevation which will provide for containment of the 100 year- 24 hour storm event within the pond. These modifications are depicted on the attached Stormwater Pond No. l Detail Sheet. At the time of development of the Holiday Inn Property, Stormwater runoff will be conveyed to Pond No. 1 by means of a new pipe connection to the pond, which will need to be constructed in conjunction with other development improvements. Stormwater runoff from the Rife Property will be conveyed to the Pond either by means of a new pipe, upsizing of the existing pipe which was constructed to serve Tract 13, or a combined use of the existing pipe and a new pipe, when the property is developed. The enclosed Drainage Calculations have assumed 85 percent impervious surfaces on the 6.90- acre Holiday Inn Property and 80 percent impervious surfaces on the 2.99-acre Rife Property. Also, the enclosed Drainage Calculations have been updated to incorporate the most current data regarding impervious/pervious areas for development tracts within Drainage Basin No. I which have been submitted to, or have obtained a General Permit from the District. Specifically, this relates to "Tract 9" which encompasses the Darden Restaurants site and the Steak 'n Shake site which together total 5.15 acres and provide for placement of 3.66 acres (71 %) impervious surface area. The attached drainage calculations address the additional contributory area to Stormwater Pond No. 1, the adjustments to the above referenced Tract 9 impervious/pervious area ratios, and the hydraulic flood routings for the 10 year-24 hour, 25 year-24 hour, and 100 year-24 hour storm events. These calculations demonstrate that the new post -development mean annual and 25 year- 24 hour peak discharge rates are still less than the previously approved pre -development peak discharge rates for the same storm events. The second aspect of this permit modification submittal pertains to construction related impacts to Wetland Nos. 2 and 3 (Pond No. 3B and Pond No. 2, respectively) for which off -site mitigation is being proposed. As you may know, the recent permit modification (Permit No. 4- 117-0369M) approved on July 11, 1995, provided for the replacement of the on -site wetland mitigation plan by preservation of an off -site regionally significant wetland parcel. The subject permit modification proposes to increase the approved off -site preservation area by 2.18 acres to offset (A) the 0.47 acre overclearing in Wetland No. 3 and (B) impacts to vegetation within Wetlands No. 2 and 3. A copy of the legal description for the 2.18 acre off -site mitigation area is enclosed. The 2.18 acre mitigation area is located adjacent to, and north of, the 25.07 acre off -site preservation area which was approved in conjunction with the recent permit modification 4-117-0369M). It is our understanding that ECOBANK is currently in the process of finalizing V Rod Pakzadian October 2, 1995 Page 3 the conservation easement language covering the combined 27.25-acre off -site wetland preservation area. Once the conservation easement language is agreed upon, the Conservation Easement will be recorded. To clarify the record regarding the conditions of permit approval pertaining to this project, and in consideration of the recent permit modification (4-117-0369M) to allow offsite wetland preservation in lieu of onsite wetland creation for impacted wetlands, we believe the following existing permit conditions (Permit No. 4-117-0369) should be removed: 12. 13, 14, 26, 27, 28, 29, 30, 31 and 33. Also, please consider the attached proposed permit condition language for inclusion in the subject permit modification regarding monitoring requirements for Wetland No. 2 and Wetland No. 3. We trust this information is sufficient for your review of the proposed project improvements. If you have any questions or need additional information, please contact us.

As you know, the proposed improvements to Pond No. 1 were considered and approved at the December 12, 1995 meeting of the SJRWMD Governing Board. The calculations submitted in conjunction with the Pond No. 1 modification did not address the issue of compensating flood storage volume for the subject properties. However. it is our desire to demonstrate at this time, rather than when the subject parcels apply for the required general permits, that compensating storage for the 10-year and 100-year flood events is provided within Stormwater Pond No. I. The following items are enclosed to facilitate your review: 1. 100-year floodplain storage calculations (3 copies. signed and sealed). 2. "Plat of Survey" Boundary and Topographic Survey for Rife Miller. Inc.. red - lined to indicate 100-Year flood elevation (30.2) (3 copies, signed and sealed). 3. "Site Demolition Plan for the Holiday Inn Property, red -lined to indicate the 100-year flood elevation (32.3) (3 copies, signed and sealed). The 100-year flood studies performed by the Federal Emergency Management Agency FEMA) have depicted isolated areas on both the Rife and the Holiday Inn properties as flood prone. However, the FEMA studies have not defined the elevation of the flood prone areas. Also, based on topographic surveys of the subject properties, the FEMA depicted flood prone areas are not consistent -with the ground topography. A flood study prepared by Singhofen and Associates. Inc. (SAI) for Seminole County, entitled "Lockhart -Smith Canal/Monroe Basin", which was completed in September engineers pla u+enz stiveyors 200 East Robinson Street - Suite 1560 • Orlando, Florida 32801 - 407/422.8062 • FAX 407/849-9401 12/14/95 15:09 TX/RX NO.0248 P.002 0 12i14/% 15:21 SCFRIMSFER - 4078%9949 NO. 415 A Mr. Rod Pakzadian December 13. 1995 Page 2 1992, estimates the 100-year flood elevation on the Rife property to be 30.2. and on the Holiday Inn property to be 32.3. This same Singhofen study was utilized to estimate the 100-year flood compensating storage requirements for the Seminole Towne Center project when permitted In July, 1993 (permit No. 4-117-0369). Based on site topography, the existing 100-year floodplain storage on the Rife property is 0.52 acre- feet; on the Holiday Inn property 1.65 acre-feet. The Singhofen study does not address a 10-year flood elevation for the subject property areas. For the purpose of this submittal, it is assumed that all of the available 100-year flood plain storage on the Rife and Holiday Inn properties is to be removed as the properties are developed. Previously approved calculations for Stormwater Pond No. 1 (permit No. 4-117-W69) accounted for 4.41 acre-feet of 100-year compensating storage volume for the Seminole Towne Center project area. Accounting for the proposed flood storage loss on the Rife and Holiday Inn properties, the total required compensating storage to be achieved in Stormwater Pond No. 1 is 6.58 acre feet (4.41 + 0.52 + 1.65). Stormwater Pond No. 1, as demonstrated in previously approved calculations, has storage capacity to detain the 100-year - 24 hour storm event without exceeding the pond top 'of bank elevations. There are approximately 33.1 acre-feet of storage provided in Stormwater Pond No. 1. therefore, compensating storage for displacement of any flood storage on the subject properties is provided in Pond No. 1. If you have any questions concerning this matter, please contact us. We respectfully request that you acknowledge, in writing, that the Rife property and the Holiday Inn property do not need to submit calculations relating to the issue of compensating flood storage when development occurs on these properties.
