CORRESPONDENCE GATOR ENGINEERING SERVICES, INC. 7289 Garejen Road, Suite 104 West Palm Beach, Florida 33404 (561 ) 841-9990 Fax (561) 841,9991 E.mail: gatoreng@aol.com October 11, 1998 City of Boynton Beach Engineering Department 100 E. Boynton Beach Blvd. Boynton Beach, FL 33435 Attention: City Engineer RE: Drainage statement for Proposed Warehouse/Office Addition for Ridgeway Plumbing at 640 E. Industrial Ave. in Boynton Beach, FL, To Whom It May Concern: l....~~ -r...t.<l rz~/?6 This letter is being written to inform the city of Boynton Beach that the site development for the proposed warehouse/office addition for Ridgeway Plumbing at 640 E. Industrial Ave. in Boynton Beach, FL meets the drainage requirements as outlined in Chapter 4, section 7.F.2 of the City of Boynton Beach's Ordinances. Additionally, per the utility department request, a evaluation of the 25 year - 3 day storm drainage runoff for this site was conducted. Per my review of the drainage calculations, it was determined that the runoff from the post-development (10.66 ac.-in.) condition of this site ~~ .I. the pre-development (11.53 ac.-in.) condition. Therefore, no additional runoff should occur onto E. Industrial Ave. after completion of these improvements. Also, 25 year - 3 day storm calculations were conducted for installation of a future control structure which will be installed after drainage improvements on E. Industrial Ave. are completed. The orifice for this future control structure would be an inverted 6"x6" triangle set at elevation 12.5 feet. Per these calculations, it was determined that the minimum perimeter elevation required for this site would need to be 14.96 feet. The perimeter elevation for this site per the drawings is set at 15.0 feet. A calculation package for this 25 year - 3 day storm is attached to this letter substantiating these findings.
