sion street. The residents feel that the volume and speed of the traffic create a danger for the young children in the area as there are no sidewalks along the street. 14th Street is the demarcation line between the single-family neighborhood to the south and the multi -family neighborhood to the north. It is also the Vero Beach/Indian River County interface. ANALYSIS: The continuity of 40th Avenue as a local subdivision road between 12th Street and State Road 60 is not desirable as it does not discourage through traffic or excessive speed. Safe pedestrian travel is also hindered by such a roadway pattern. On January 19, 1983, the County Commission vacated the plat of Ravina Gardens Subdivision which was to be developed immediate- ly west of Phyl-Ann Terrace. The plat depicted a single street (41st Avenue) extending from 12th Street north to 14th Street. 41st Avenue was to continue north to 16th Street through a multi -family development. At the time of vacation of the Ravina Gardens plat, the Commission granted preliminary plat approval for Laurel Court Subdivision. Laurel Court was designed with access off of 12th Street and a cul-de-sac at 14th Street in order to separate the single-family subdivision from the multi -family neighborhood to the north. The approved plat is identical to the situation which the residents of Phyl-Ann Terrace wish to create. Planning principles incor- porated into the Comprehensive Plan encourage the separation of multi -family and single-family neighborhoods. The proposed project will serve as a buffer between the differing high and low intensity uses and decrease the volume of through traffic entering both the single-family neighborhood and multi -family neighborhood, an area populated by even more children than the single-family section. Existing right-of-way on 40th Avenue is 60 feet, which is adequate to construct a cul-de-sac with a 30 foot radius. It will be necessary to obtain additional right-of-way around the cul-de-sac in order to ensure proper drainage. Currently the lots drain towards the front, and miami curbs route the run-off towards 12th Street.. The construction of the cul-de-sac at 14th Street will not inhibit the existing drainage pattern. It is recommended that portions of the pavement in the 13th Street right-of-way be removed in order to allow for an even more improved drainage system. A section of pavement will have to remain as the residence at the northeast corner of 40th Avenue and 13th Street is accessed off of 13th Street. Law enforcement, fire, and ambulance service to the residents of 40th Avenue between 12th and 16th Streets will not be negatively impacted by the proposed cul-de-sac. The multi- family area to the north will be easily accessed via 16th Street and Phyl-Ann Terrace by way of 12th Street. Due to the fact that there are 10 projects on the waiting list for then County Petition Paving Program, the proposed project could not be scheduled for approximately 9 months. It would be preferable for the construction to be done by an outside contractor, although the engineering can be done by the County Engineering Department. It is also recommended that the County not be responsible for maintaining the landscaped area designed as a buffer for the cul-de-sac. RECOMMENDATION: The Planning Staff recommends that the Board grant conceptual approval of the right-of-way abandonment and instruct the Engineering Department to prepare construction drawings of the cul-de-sac and a preliminary assessment. It is recommended that the Engineering Department then advertise a public hearing regarding the abandonment of right-of-way and the retention of easements, approval of which should be followed by the creation of the actual assessment roll. 47 J UN 6 1984 BOOK 57 PAGE 3x,19 f
