1 ENVIRONMENTAL RESOURCE PERMIT INDIVIDUAL - TECHNICAL STAFF REPORT 31-Oct-2017 APPLICATION #: IND Applicant: Agent: Nirav Banker BPS Partners, LLC 504 Parkwood Drive Panama City, FL Bethany Womack Cypress Environmenta P.O. Box Panama City, FL (850) Project Name: Hampton Callaway Acres Owned: Project Acreage: County: Bay STR: Section(s): Township(s): Range(s): 6 4S 13W Receiving Water Body: Name Tributary of Callaway Bayou Class III Fresh Authority (2)(c), (2)(a), (2)(d) Final O&M Entity: BPS Partners, LLC ERP Conservation Easements/Restrictions: No Interested Parties: No Objectors: No Authorization Statement: The construction of a surface water management system associated with a new development located on an undeveloped parcel to the north of 902 Tyndall Parkway, in Callaway, (Bay County). The surface water management system will include the construction, operation, and maintenance of a wet detention pond without a littoral zone, designed to provide treatment and attenuation for approximately 2.63 acres. The new development will include the construction of new commercial hotel building with associated parking area, drive aisles, and two driveway connections to the access driveway associated with the adjacent property to the south of the parcel. Stormwater runoff from the development will be directed toward a series of drainage inlets to be installed throughout the development and piped toward the perimeter of the pond. The wet detention pond has been designed with an interconnected control structure which will include two modified Type E Inlets (DS-10 and DS-11) with DS-10 equipped with a inch orifice set at the permanent pool volume elevation of 31.0 feet, a 4-inch circular weir set at an elevation of 31.8 feet, and an 18-inch by 12-inch rectangular weir set at an elevation of 33.6 feet, and with DS-11 to be constructed with a top of grate set at an elevation of 34.4 feet. The project includes direct impacts to wetlands and other surface waters over an area of approximately 0.12 acres. Impacts to wetlands will be offset through the purchase of wetland mitigation credits from the Sweetwater Mitigation Bank. The surface water management system is in accordance with the approved plans prepared by Panhandle Engineering, Inc.

2 Recommendation: Approval Reviewers: Dana Palermo, P.E.; Ted Reese Engineering Comments: The existing site conditions appear to be suitable for wet detention due to the site having low infiltrating soils, an average onsite groundwater table at or just above existing grade, and a positive discharge offsite. The system consists of a wet detention pond designed to provide treatment and attenuation for the 2.63 acre drainage basin (limits of disturbance). The proposed project consists of the construction of a new commercial hotel building with associated parking area, drive aisles, and two driveway connections to the access driveway associated with the adjacent property to the south of the parcel. The proposed wet detention pond is to be located along the western portion of the project site, with conveyance swales located along the northern and southern portions of the development, which has been designed to provide the same amount of required treatment volume of approximately acre-feet. The proposed wet detention pond has been designed to recover half the required treatment volume within 48 to 60 hours. The wet detention pond has been designed without a littoral zone and will provide 50 percent additional permanent pool volume to meet the requirements of Section 8.6 of A.H. Vol. II. The wet detention pond has been designed with two interconnected control structures to be constructed near the northwestern corner of the pond. The control structures will consist of two modified Type E Inlets (DS-10 and DS-11) with DS-10 equipped with a inch orifice set at the permanent pool volume elevation of 31.0 feet, a 4-inch circular weir set at an elevation of 31.8 feet, and an 18-inch by 12-inch rectangular weir set at an elevation of 33.6 feet, and with DS-11 to be constructed with a top of grate set at an elevation of 34.4 feet. The interconnected discharge structure has been designed to discharge offsite toward the north to daylight into the existing drainage ditch located near the northwestern corner of the project site. The proposed impervious areas were calculated to be more than 50% of the project area, so therefore attenuation for the 2 year/ 24 hour storm event in accordance with Section of Applicant s Handbook Volume II is required. The proposed wet detention pond has been designed to have approximately 0.62 cubic feet per second discharging during the post-development analysis through the control structure for the 2 year / 24 hour storm event which appears to be less than the pre-development discharge rate that was calculated to be approximately 5.40 cubic feet per second. Therefore the proposed pond appears to meet this requirement.

3 The proposed wet detention pond appears to be a suitable Best Management Practice for the proposed development. The surface water management system appears to have been designed in accordance with the requirements of the Northwest Florida Water Management District. The proposed surface water management system will be operated and maintained by the developer, BPS Partners, LLC. Environmental Comments: Wetlands and other surface waters are located on the site, over approximately 0.21 acres which are located along the periphery of the site, as delineated by Cypress Environmental, and verified by District staff on October 12, Wetlands are predominantly hydric pine flatwoods of marginal quality with pockets of hydric pine savanna and mixed forested wetlands. The project has been designed to minimize impacts and includes permanent (fill) impacts to 0.12 acres of wetlands. Remaining wetlands are to be undisturbed with the exception of temporary clearing for the construction and installation of sediment and erosion controls. These areas as well as an additional area of 0.17 acres of adjacent wetlands on the properties to the north and east have been assessed for secondary (indirect) impacts. Mitigation to offset unavoidable wetland impacts is proposed through the purchase of 0.06 mitigation bank credits from Sweetwater Mitigation Bank which services the area. The proposed project with mitigation should not cause an adverse impact to water resources of the District. Upland areas onsite are characterized as mesic slash pine flatwoods with some oaks and other hardwoods. Understory and groundcover vegetation consists primarily of saw palmetto, gallberry, broom sedge, and various grasses. The uplands and wetlands on site appear to have been previously impacted by clearing, and silviculture activities. Wetlands on site are marginal in quality. The location and landscape functions of onsite wetlands are low due to the proximity of the roadway along the western boundary, a large conveyance ditch on the north side, and commercial development to the south. There is a large tract of undeveloped uplands and wetlands to the east which eventually connects through ditches to Callaway Bayou. No evidence of listed species was observed. However, the site has potential habitat for state and federally listed species including: Eastern indigo snake (Drymarchon corais couperi), and Gopher tortoise (Gopherus polyphemus). Also, the site is located within the known range of the statelisted Panama City crayfish (Procambarus econfinea). A site-specific survey for these species was conducted which found no evidence for them within the project site. Notice of the Application was sent to the Florida Fish and Wildlife Conservation Commission (FWC) as well as the Department of State, Division of Historical Resources (DHR) on October 11, A letter was received from DHR dated October 12, 2017, indicating the project was not likely to affect historic properties. No correspondence has been received from FWC regarding the project. Site Description: The approximately 2.63 acre project site consists of an undeveloped property located to the north of 902 Tyndall Parkway, in Callaway, (Bay County). The site is relatively flat

4 with the site primarily sloping toward the north. The site is bordered by Tyndall Parkway along the western side, an access driveway associated with the adjacent commercial development along the southern side, and wetlands along the northern and eastern sides of the project site. The wetlands located along the eastern and northern sides of the project site have been delineated and appear to extend toward the north. There is a drainageway associated with a cross culvert located near the northwestern corner of the project site that appears to drain offsite toward an existing conveyance system directed to Callaway Bayou.
