Context The subject parcel has two existing residences and several outbuildings facing Avon Street Extended, with the remainder of the lot being wooded. The property is located south of Avon Park I, which includes a mix of detached and attached residential units. Other surrounding uses include single family detached dwellings on residentially zoned lots. Industrial uses are also located nearby along Avon Street. Visibility The development will be visible from the Entrance Corridor. The site currently slopes upward from Avon Street Extended. It is expected that the single family homes will screen the majority of the attached units from view. However, due to the slope of the site, the roofs and some portion of the attached units could be visible, depending on the heights of the structures. A biofilter, recreation shelter and tot lot are located close to the EC and will be readily visible. ARB Meeting Date April 21, 2014 Staff Contact Margaret Maliszewski PROJECT HISTORY This property was originally rezoned in 2007 (ZMA2007 -05) from R1 to R6. The ARB reviewed preliminary and final site development plans (ARB2007 -138 and ARB- 2008 -12) following the approval of that rezoning. The approved site plan had a similar layout to the current proposal, but included more attached units than detached, and it included more landscaping along Avon Street Extended and around the stormwater facility than is shown in the current proposal. A second rezoning on the property, from R6 Residential to Planned Residential Development, was approved by the Board of Supervisors in December of 2013. That rezoning permitted the 32 units as shown on the current plan. ARB staff had no objection to the rezoning. The application plan included more landscaping along the EC and around the stormwater facility than is shown in the current site plan.

Photographs of historic buildings in the area, as well as drawings of architectural features, which provide important examples of this tradition are contained in Appendix A. 9 Building forms and features, including roofs, windows, doors, materials, colors and textures should be compatible with the forms and features of the significant historic buildings in the area, exemplified by (but not limited to) the buildings described in Appendix A [of the design guidelines]. The standard of compatibility can be met through scale, materials, and forms which may be embodied in architecture which is contemporary as well as traditional.

The Guidelines allow in the first phase of Avon Park individuality in design to accommodate varying tastes as well as development. special functional requirements. 5 It is also an important objective of the Guidelines to establish a pattern of compatible architectural characteristics throughout the Entrance Corridor in order to achieve unity and coherence. Building designs should demonstrate sensitivity to other nearby structures within the Entrance Corridor. Where a designated corridor is substantially developed, these Guidelines require striking a careful balance between harmonizing new development with the existing character of the corridor and achieving compatibility with the significant historic sites in the area. 10 Buildings should relate to their site and the surrounding context of buildings. 11 The overall design of buildings should have human scale. Scale should be integral to the building and site design. 12 Architecture proposed within the Entrance Corridor should use forms, shapes, scale, and materials to create a cohesive whole. 13 Any appearance of "blankness" resulting from building design hould be relieved using design detail or vegetation, or both. 14 PIrcades, colonnades, or other architectural connecting devices hould be used to unify groups of buildings within a development.

Lighting The locations of street and path lights are shown on the site plan, but lighting details have not been Provide complete lighting provided. information for review. Add the standard lighting note to the site plan. Staff recommends the following as the primary points of discussion: 1. The appearance /treatment of the stormwater facility at the entrance to the site, adjacent to the EC, and landscaping along Avon Street Extended 2. Anticipated visibility of the proposed attached units on lots 8 -10 and 24 -26 from the EC 3. Type /extent of future ARB review Staff recommends that the ARB forward the following recommendations to the agent: — Regarding requirements to satisfy the design guidelines: o As per § 18- 30.6.4(2), (3) and (5) and Guideline #20, the biofilter has the appearance of an engineered structure and it is not fully integrated into the landscape. Regarding recommendations on the plan as it relates to the guidelines: None. Regarding recommended conditions of initial plan approval: • A Certificate of Appropriateness is required prior to final site plan approval. • Revise the design of the stormwater facility to eliminate the engineered appearance and to make it an integrated landscape element. Regarding conditions to be satisfied prior to issuance of a grading permit: • Provide a conservation checklist on the plan. • Show tree protection fencing on the plan. Staff offers the following comments on the initial plan for the benefit of the applicant's next ARB submittal: 1. Provide architectural elevations and material samples for the attached units. Coordinate building materials with those used in existing buildings in the area. 2. Provide for review an architectural plan and elevations for the recreation shelter. 3. Include on the site plan a detail for the tot lot fence, including notes on colors and materials. Note that chain link is not appropriate in the ECs. 4. Provide details on the plan illustrating the appearance of the maintenance access drive and chained access point. Show how these features will have an appropriate appearance for the EC. 5. Revise the design of the stormwater facility to eliminate the engineered appearance and to make it an integrated landscape element. 6. If biofilter plants are proposed, show them on the landscape plan. 7. Add the standard mechanical equipment note to the site plan and the architectural plans. "Visibility of all mechanical equipment from the Entrance Corridor shall be eliminated." 8. Increase the tree save area. 9. Locate large street trees along Avon Street Extended no more than 35 feet on center. Intersperse ornamental trees among the large trees at a less regular pattern to achieve a more natural appearance. See ARB2008 -12 and ZMA2012 -04 for acceptable landscape design. 10. Provide a complete landscape plan for review, including tree species and sizes. 11. Rearrange utilities to allow for continuous street trees along interior streets. Provide a complete landscape plan for review. 12. Add the standard landscape note to the plan. "All site plantings of trees and shrubs shall be allowed to reach, and be maintained at, mature height; the topping of trees is prohibited. Shrubs and trees shall be pruned minimally and only to support the overall health of the plant." 13. Add trees in an irregular pattern on the new slopes proposed with regular grades. 14. Revise the grading plan to round contours with a ten foot minimum radius where they meet the adjacent condition, for a natural appearance. 15. Provide a conservation checklist on the plan. Show tree protection fencing on the plan. 16. Provide complete lighting information for review. Add the standard lighting note to the site plan.
