Required improvements. All future subdivisions and site plans for development in multiple-family districts shall install the following improvements, designed and constructed to meet the requirements and specifications of the Code of Laws and Ordinances of Indian River County and the State of Florida.

Bikeways. The project developer shall be responsible for providing a bikeway(s) along the project site's frontage on all rights-of-way or easements if such bikeway facility is designated in the Indian River County Comprehensive Bikeway and Sidewalk Plan.

Sidewalks: The project developer shall be responsible for providing a sidewalk(s) along the project site's frontage on all rights-of-way (existing or created via the project plat) and/or street easements (existing or created via the project plat) if such sidewalk facility is designated in the Indian River County Comprehensive Bikeway and Sidewalk Plan or required in the site's applicable zoning district. Five-foot wide sidewalks shall also be required on both sides of all interior streets within rights-of-way and/or easements (existing or created via the project plat). A minimum six-foot strip of irrigated, approved ground cover or sodded landscape area shall be provided between the curb and the sidewalk with canopy trees provided every fifty (50) feet.

*C.

Curbs: Curbing, or other barrier approved by the county engineer, is required to be installed between all sidewalks and adjacent interior roadways and parking areas.

*D.

Green space and/or recreation space: All multi-family developments must set aside a minimum of seven and one-half (7.5) percent of the total project site area as dedicated to green space and/or recreation space. Upland preserve, wetland areas, and created littoral zones may be credited toward this requirement. Recreation tracts shall be located, designed, constructed, maintained and operated in such a manner that minimizes adverse noise and lighting impacts on adjacent or nearby developments. For purposes of this regulation, "recreation space" may include recreational facilities and amenities such as parks, ball courts, and pools. Common spaces credited toward meeting this requirement shall be located and designed to be conveniently accessible to all project residents, and shall be sized, located, and designed to function as a project amenity such as a park, conservation area, open air recreation facility, or other similar type of amenity.

Recreation tracts located within one hundred twenty-five (125) feet of the boundary of the development shall be either:

Designated on a final plat, or other document recorded in the public records, as being used for passive recreation uses: no active uses, such as but not limited to basketball or tennis courts, shall be permitted on these tracts.

Buffered from adjacent development boundaries with a minimum twenty-five (25) foot wide Type B (or better) buffer with a six-foot opaque feature (see Chapter 926).

Any and all lighting used within recreation tracts shall be approved by the county and shall be adequately shielded to prevent lighting or glare from encroaching on to properties adjacent to or nearby the development.

*E.

Stormwater management: Open swales along the sides of internal project streets are not permitted. A stormwater management system shall be constructed in accordance with the requirements of Chapter 930. Stormwater shall be retained in a lake for all multi-family developments. Drainage swales shall be permitted only for conveyance purposes and not for capacity calculations. Dry detention may be used only in circumstances where retention in a lake conflicts with the aquifer recharge criteria, where existing trees and vegetation can be preserved in and around a dry detention area, or where approved by the public works director if warranted by soils or other site characteristics in accordance with Chapter 930 provisions and regulations.

*F.

Dedication of rights-of-way: All right-of-way areas set aside for future roadway improvements shall be landscaped, and irrigated to the edge of the paved roadway by the developer and/or homeowner's associations. Maintenance of the right-of-way areas shall be the responsibility of the developer and/or homeowner's association.

*G.

Internal pedestrian systems: Within projects an internal pedestrian system shall be provided which connects to the off-site public sidewalk/pedestrian system. The internal system shall provide five-foot wide sidewalks, or other surface approved by the county engineer, which serve each unit and internal recreation and amenity area.

* NOTE: The requirements of items C, D, E, F, and G shall not apply to legally established individual lots and parcels of record upon which no more than three (3) residential units are proposed.

RM-8	C—3 ft. Opaque
RM-10	C—3 ft. Opaque
