Dr. Evenson said the entire property is approximately 5.01 acres and is in the Canadian River floodplain. Dr. Evenson said the Applicants were proposing to construct an approximately 36’ x 26’ in-ground pool and an approximately 28’ x 14’ concrete deck/patio surrounding the pool. Dr. Evenson said according to the Applicant’s Engineer, total area for the pool and surrounding concrete is 50’ x 32’ and will be located to the southwest of the house. Dr. Evenson reviewed aerial photographs of the property and the location of the proposed pool. Dr. Evenson said according to the engineer’s calculations, approximately 15 cubic yards of fill in the form of concrete will be brought into the floodplain and approximately 15 cubic yards of compensatory storage will be provided in the southwest corner of the property. Dr. Evenson reviewed the applicable floodplain ordinances and confirmed all ordinance requirements have been met. Dr. Evenson said staff recommended approval of Floodplain Permit Application No. 631. Mr. O’Leary asked if there were any comments from the engineer. Mr. Agrawal said the presentation was thorough. Mr. O’Leary asked for questions from the committee or a motion. Ms. Jane Hudson asked if the applicant had submitted the design to Development Servies to obtain a Pool Permit. Mr. Agrawal said that he was unsure of the status of the Pool Permit but that he would check with the builder and follow up with Dr. Evenson. Mr. Sturtz recommended approval of Floodplain Permit Application No. 631 with the condition that an as-built survey of the compensatory storage location be submitted upon completion. Mr. Scanlon seconded the motion. Mrs. Shepard called roll, and the committee voted to approve the application 5-0. Item No. 3, Miscellaneous Discussion: a) Mr. O’Leary stated that there were two applications pending for the May 17, 2021 meeting. Floodplain Permit Committee Meeting May 3, 2021 Page 3 b) Mr. O’Leary said the June 7, 2021 meeting had no pending applications at this time. Mr. O’Leary said the previous week was a great reminder of why floodplain management is so important. Dr. Evenson said the recent rain event was very intense and if it had remained in Norman for an hour it would have been a 7 inch per hour event, thankfully the storm moved out of Norman within half an hour. Dr. Evenson said the northwest side of town in particular experienced intense rainfall and allowed for a visual representation of the floodplain. Dr. Evenson said during site inspections of the Ten Mile Flat Creek floodplain, she identified a location that had been previously granted a floodplain permit that would have been flooded had the structure not been elevated. Mr. Scanlon noted that the recent storm created so much debris that stormwater drains and inlets were quickly clogged and water backed up. Mr. Scanlon said he would like to see neighborhoods assist in clearing those structures because of the limited staff available in the Stormwater Division to address those needs. Dr. Evenson and Mr. Sturtz said residents had called concerned with standing water and drainage concerns. Item No. 4, Adjournment: Mr. O’Leary called for a motion to adjourn. Mr. Sturtz motioned to adjourn and was seconded by Mr. Scanlon. Mrs. Shepard called roll, and the motion was approved 5-0. Meeting adjourned at 3:43 p.m.
