Oklahoma have employed R.D. Flanagan & Associates to coordinate, research and assemble Multi-Hazard Mitigation Plans in accordance with FEMA guidelines. Using the process developed by Ron Flanagan organizations accurately identify hazards, mitigation strategies and develop a plan for implementation and maintenance of mitigation plans. FEMA has reviewed and accepted the Tulsa, Oklahoma Multi-Hazard Mitigation Plan developed by R.D. Flanagan & Associates. Plans have been completed, approved by the State of Oklahoma and submitted to FEMA for Pryor, Bixby, Yukon, El Reno, Calumet, Piedmont, Union City, Mustang, Canadian County, Creek County, Glenpool, Jenks and Sapulpa.
Hazard Mitigation Grant Program Workshops
|At the request of the State of Oklahoma R.D. Flanagan & Associates hosted five workshops at various locations in the state during 2003 and another Workshop was held in 2004 describing what Hazard Mitigation Planning is, why it is important to communities, counties and tribes and options on how to create a plan. Connie Dill, from the Oklahoma Department of Emergency Management, and Ron Flanagan took workshop participants through each phase of creating a Hazard Mitigation Plan, showed examples of successful plans and provided information and resources to participants.|
Central Park, excluding the City's senior citizen recreation center and portions of its parking lot, will serve as a proposed detention facility. Though the facility will be largely excavated, a low-flow channel will contain and fully convey runoff up to the 5-year event. This will preserve the park setting except in extreme storm events. The channel will replace the arch storm sewer within the pond. The final design may incorporate an enclosed conduit instead of the open channel to further utilize park area. The final facility surface area will be 13.5 acres with a peak 100-year storage volume of 129.7 acre-feet. The maximum ponding depths will range from 8.0 feet in the upper reaches of the facility to 18.0 feet at the outlet. Storm runoff will enter the facility from three primary locations; the storm sewer running along Norfolk Avenue, the 6th Street existing culvert and proposed pipe (or equivalent box) located near 6th Street. The outlet control of the facility will be a 160-square-foot restrictive opening situated at the entrance to the arch storm sewer near the intersection of Madison Avenue and 8th Street.
In September 2003 the City of Tulsa was honored by FEMA under the Department of Homeland Security for becoming the first city in the nation to receive a Community Rating System rating of 2. As a result Tulsans in the Special Hazard Flood Areas receive a 40% discount on flood insurance.
R.D. Flanagan & Associates has provided planning consultation to the City of Tulsa's CRS Program since 1990. The City of Tulsa has used R.D. Flanagan & Associates as the primary consultant for their recertification and three-year cycle re-applications / verifications.
The Mingo Creek Stormwater Detention Facilities are designed to serve as park, recreation and space facilities. The project was selected by the National Park Service, Association of State Floodplain Managers, and the Association of State Wetland Managers as one of eight case studies throughout the nation of successful multi-objective river corridor management examples.
The multi-disciplinary team, consisting of Freese and Nichols, Inc., engineering consultants, Jim Richards Studio, landscape architects, Robert Searns, trails planner, Robbin B. Sotir & Assocaties, bioengineering, and Jaster Quintanilla & Associates developed the conceptual plan for the 3.7 mile extension of the famous River Walk. The plan serviced as the basis for subsequent work and detailed plans.
Consultants conducted a national study on the state-of-the-art in developing watershed master drainage planning process and worked with city engineering staff responsible for developing hydraulic and hydrologic models. Consultants in turn developed the study format, identified drainage characteristics, problem areas, conducted the resource inventory, zoning and land-use inventory and full urbanization projections and developed the Vensel Creek park, recreation, and open-space plan.
Consultants were responsible for public information and education, planning and conduct of public input, participation and presentation meetings. The final work product was the development of Tulsa’s first master drainage and trails plan.
Since the Vensel Creek Trail Plan the City of Tulsa has completed master drainage plans on all drainage basins and multi-use trails within its jurisdiction of over 150 square miles. Detailed design and implementation plans were developed for the Brookwood Detention Facility. This plan involved extensive citizen participation and resulted in a park-like facility with a permanent water feature, landscaping and trails.
Each of the eight sites and their greenway corridors were unique and required individual analysis and design treatment. The East Central High School site was located on the site of the community high school and the design had to incorporate a football field and stadium as well as a soccer field and two baseball diamonds. The Wright Middle School site incorporated baseball diamonds, soccer fields and jogging trails into the design.
The Holiday Park site, located at the intersection of two expressways and a major street, was designed to accommodate a City of Tulsa Training Facility.
The Cooley Lake and Sampson Lake sites were designed to serve as passive recreation facilities with a permanent water feature and trail systems. The Tupelo site was a challenging redesign and retrofit of an older existing detention facility. The design team transformed the rather unattractive, single-purpose facility into a multi-use site with a permanent water feature, re-forestation, site sculpting, baseball and soccer fields, and multi-use trails.
The project involved developing multi-use maintenance/recreation trail criteria and standards, which have subsequently been widely adopted throughout the nation as the standard for maintenance trails. The Maintenance Trail Plan was adopted and incorporated into the regional Park, Recreation and Open-Space Plan and various District Comprehensive Plans.
Ron Flanagan’s solution was to create artificial detention sites that imitate nature by ponding runoff during spring and fall rains, but for the rest of the year serve as parks, playing fields and wildlife habitat.
The project involved extensive citizen involvement, interagency inter-governmental cooperation and coordination, extensive inventory, alternative development and refinement of the selected plan.
