R <br />eooK 91 FacF101 <br />The comments raised by this memorandum deal with s review of the LACK of design <br />standards that are being utilized for this major driveway to serve the Outlet Mall at Vero <br />Beach, as well as adjacent properties owned by others. The Manual On Uniform <br />State of Florida, even though applicable to public streets and highways in Florida, has <br />been utilized in a number of cases in the State of Florida which indicate that when a <br />roadway, public or private, invites the public to enter and utilize the facilities then the <br />designer and the person that constructs the roadway should, as a minimum, meet those <br />standards as set forth within the manual. <br />Our review of the design dated 1127194 is as follows: <br />P_ <br />The reverse curves at the north end are approximately 112' radii. A radius this sharp <br />would require an 8% cross -slope superelevatlon for a 20 mph design speed, however, <br />because they are so close together it is impossible to develop this cross -slope. <br />Also an 8% cross -slope would require almost a 7 ft. difference between the right and left <br />side of the roadway. <br />PABT 11 <br />The southern most curve appears to be a 180' radius. This sharp of a curve would <br />require a 40A cross -slope. For the same reasons as above, this is not acceptable. The <br />relation of the southern curve to the northern reverse curves is less than sharp <br />(approximately 100). The curves are what Is referred to as broken back curves. Broken <br />back curves are not an acceptable design. <br />Based on our professional review, I would recommend strongly that the roadway to serve <br />the outlet Mall and other properties be designed in such a fashion as to provide safe and <br />adequate access in the future and that any modification to the median on a temporary <br />basis be considered so that ultimately the property to the north of SR 60 develops that <br />everything can be served by one properly designed intersection. My recommendation <br />would be that this roadway needs to be realigned and straightened in order to eliminate <br />the undesirable and unsafe curves that currently exist. <br />Yours truly, <br />AND SCHNARS, P.A. <br />Arnold Ramos, PE., P.L. <br />Executive Vice President <br />8900 North Andrews Avenue - Ft.
