03 C i VZ6 1991 BOOK 85 PA;E9,9 The provision of above -grade crossings eliminates the potential for golf cart/vehicular/pedestrian conflicts which would likely occur given the current nature of traffic and travel patterns in the area. It should be noted that traffic volumes in the area are expected to increase in the future as the surrounding area continues to develop. Therefore, staff recommends that the applicant be required to provide..above-: grade overpass golf cart crossings for the project at 6th Avenue S.W. and 23rd Street S.W. Public Work's golf cart crossing assessment is contained in attachment 4b. The Planning and Zoning Commission's recommendation Incorporated the applicant's request to provide at -grade, non - electronically signalized mid -block cart crossings. Staff does not agree with the Planning and Zoning Commission's recommendation to require non -electronically signalized crossings. In staff's opinion, at -grade electronically signalized mid -block crossing control- (Option- #3) is the minimum acceptable form of crossing control under certain circumstances. Such electronic signals would be self - actualized, activated by the golf cart occupant, which would activate a stop light signal to halt vehicular traffic. Provision of such signalized crossings could provide an acceptable method of formalized crossing control if--area- motorists respect the signal indications and if -the signals are activated only when a cart needs to make a crossing movement.*.The applicant has indicated that provision of at - grade, electronically signalized mid -block cart crossings may be. acceptable in the future should the non -electronically signalized crossings initially proposed by the applicant (Option #5) prove hazardous or ineffective. However, the applicant is reluctant to agree to providing electronic crossings up front. _ Staff recommends that the Board of County Commissioners require that the applicant provide above -grade card crossings. Should the Board determine that above -grade crossings are not necessary, then staff would recommend that the applicant be required to provide at -grade, electronically signalized mid - block cart crossings. 7. ENVIRONMENTAL ISSUES: • Upland Habitat: Since the subject property is greater than 5 acres in size, the project is required to provide for the preservation of on-site upland habitat areas, pursuant to the provisions of Section 929.05. The applicant has determined, and staff concurs, that 74 acres of the site consist of native upland habitat. Compliance with the county's preservation requirement will require that the applicant provide for the preservation of 10 to 15% of the 74 acres of upland habitat. The applicant has acknowledged on the conceptual plan that the project will comply with the preservation requirement. Staff concurs with the applicant that the proposed conceptual plan indicates that the conceptual plan design 'will accomodate satisfaction of the upland habitat preservation requirement on the site. Specific provisions (e.g. delineation of Conservation Easements, etc.) will be addressed during the project's subsequent preliminary PD reviews. • Wetlands: Examination of the subject property indicates that wetland areas exist on the property. The applicant has noted that some wetland areas will be preserved, while othar"s will be altered. The concept plan depicts additional - wetland creation as mitigation for the wetlands alteration. 44 4
