3FOREWORD: THE IMPORTANCE OF THE STREET

Hobe Sound is a wonderful place to live, work, shop and relax. Bridge Road, its main commercial street, offers businesses great exposure, convenient access and alocation that is hard to match. Nevertheless, this road remains inconvenient for pedestrians because of its narrow and interrupted sidewalks, and the speed atwhich cars travel along it.

The memorable character of Hobe Sound, as well as in other communities, is established in its streets and public spaces. Main streets, like A1A and Bridge Roadshape the impression that many people have of Hobe Sound. Therefore, these streets should be comfortable, safe, pleasing and even enlightening in terms of theexperience they offer of the area.

Living, working and shopping in downtown Hobe Sound should be one of the delights of the community. Healthy neighborhoods and charming community lifeshould be blooming around this downtown area. In order to accomplish this vision, Martin County, working closely with the Neighborhood Advisory Committee,recently adopted a master plan and an overlay zoning code to allow for development in the residents’ terms, by encouraging parking lots to connect, maintaininguniform setbacks and building heights, and defining permitted uses in downtown.

Additionally, the Hobe Sound Neighborhood Advisory Committee (NAC), together with Treasure Coast Regional Planning Council and Martin County staff,have developed this report which contains Architectural Design Regulations for buildings along the community’s downtown streets. These regulations, togetherwith the recently adopted master plan, should be used as a means to achieve the community’s positive lasting impression.

HOW TO USE THESE GUIDELINES:

Section I - General Urban Guidelines: The regulations and control elements for development and new construction along Bridge Road and A1A are incorporated in aStreet Type Regulating Plan and a code sheet for each street type; containing information regarding building siting, height and use. Additionally, street sectionsand specific recommendations for each street type are included in this section.Section II - TThe Elements of Safe and Healthy Streets: describes street furniture, sidewalks and general urban considerations.Section III - Building Types: identifies preferred building types and their requirements.Section IV - Architecture and Character: contains information regarding architectural styles, proportions and preferred materials.The outline below describes how to use these regulations.1- Determine the location of the parcel by using the regulating plan on page 5.2- Buildings are regulated by building type and are restricted by the street type they enfront. All buildings shall be designated as one of the types described inSection III. To determine which building types are permitted on what types of streets, see the Street Type regulating plan. If the building site is on a corner, thestreet of greater hierarchy controls.3 - Refer to the Mixed-Use Overlay tables on pages 7 and 10 for regulations that apply to each building and its site.4- Select architectural style and refer to Section VI for proportions and description of architectural elements.

REGARDING THE STREET: BRIDGE ROAD 6

Proposed Changes:

- Convert the existing two-way street with no parking to two 10' travel lanes with 8’ parallel parking on both sides. Narrowing the roadway will allow for wider side-walks. This will cause auto traffic to move at slower, safer speeds and will invite pedestrians to spend more time on it. It will also make for a better transition betweenthe commercial area on US 1 and A1A and the surrounding neighborhoods.- Shield parking lanes on both sides of the street and add bump-outs in the middle of the block. As part of the sidewalk widening program, bump-outs should beadded at intersections and every three to five parked cars. These extensions of the sidewalk will cut pedestrian time crossing, reduce traffic speed and create a senseof enclosure. These bump-outs also serve as planting areas.- Additional parking should be accommodated behind the buildings and in designated shared parking areas.- New construction should be built to the property line and should have awnings to protect pedestrians from sun and rain.

Existing Condition:

Two travel lanes, no on-street parking and little or no landscaping. Allof these factors encourage high speed and damage the pedestrian qual-ity of the environment. The vehicular predominance of this street isfurther enhanced by nonexistent sidewalks or in many cases, sidewalksinterrupted by head-in parking.

Buildings along Bridge Road are generally pushed back from the streetline. Setbacks are large and uneven.This creates an ambivalent zonealong the street which only continues to blur its structure. This lack ofstructural clarity is enhanced by the lack of trees and disparity in build-ing types and placement.

BRIDGE ROAD LOOKING WEST: EXISTING CONDITION 8




BRIDGE ROAD LOOKING WEST: CHANGE OVER TIME 9
















BRIDGE ROAD: POTENTIAL ULTIMATE BUILD-OUT AS PROPOSED BY OVERLAY ZONING CODE 13


Existing Condition:

One very wide, southbound travel lane, with angled on-street parking on the east, opposite to the retail.This condition again gives supremacy to the car over the pedestrian. Visitors find themselves constant-ly crossing a vehicular way to access retail.

Proposed Changes:

- The one-way street with angled parking is widely accepted by the community. The width of the travellane is such that it is possible to maintain this condition and widen the existing sidewalk in front of thebusinesses along this road.- The depth of the angled parking should be reduced by three feet. The travel lane should be reducedby one foot. These four feet should be added to the existing five feet of sidewalk on the west side of

A1A, increasing its width from 5 to 9 feet.- Shield parking lanes adding bump-outson intersections and in the middle of theblock. Bump-outs reduce the pedestrianexposure to moving vehicles by cuttingpedestrian crossing time by reducing cross-ing areas to 10 feet, and at the same time,maintain a constant, narrow, and trafficcalmed section while cars are not parked.Bump-outs should be also used as planters.

SECTION IITHE ELEMENTS OF

SAFE AND HEALTHY STREETS




17SIDEWALKS

Do Not:- Build commercial sidewalks narrower than 7’ (whenever possible)- Interrupt sidewalks with trees, street lights and other public or

private elements.- Create continuous planting strips next to on-street parking on com

mercial streets.- Allow for head-in or angled parking on the main street (Bridge Road).

This type of parking should be reserved for side streets and A1A.- Interrupt sidewalks with parking, driveways, or large curb-cuts (when-

ever possible or when there is an alley)- Build driveways larger than 30’- Design sidewalks that leave the pedestrian exposed to sun, rain

and moving cars.

Do:- Build sidewalks between 10 and 15 feet in width(for commercial streets,

whenever possible).- Allow for grates or small planting areas (along commercial streets).- Plant and align trees between the sidewalk and the street.- Align street lights at regular intervals between trees.- Keep sidewalks free of obstructions- Incorporate on-street parallel parking.- Build bump-outs at corners to shield parked cars, reduce speed and

maintain a constant, narrow, street section.- Use bump-outs to reduce the pedestrian crossing time and distance.- Use bump-outs as planters.- Use concrete, stamped concrete, or pavers as a finish.

Certain physical qualities are required for great streets. Sidewalks where people can walk easily and safely seem like an obvious and easy goal toachieve. But that alone doesn't create a great street or even a sense of place. Only healthy streets contribute to that sense of place. It is the combi-nation of a number of elements, not just one or two, that contributes to creating unforgettable mental images. These elements and the way theyrelate, are necessary to achieve a sense of place in any street or neighborhood. The pages that follow list and describe these elements and analyzehow they have been incorporated into the streetscape in Hobe Sound.

The images below illustrate a few general rules regarding sidewalks:




18REGARDING SIDEWALKS: BRIDGE ROAD

The images that follow show the condition of sidewalksalong Bridge Road and A1A.

Bridge Road: Existing Condition (Left):

Bridge Road has been dealing with parking in the mostdamaging way both to its image and to the pedestrian.Each business is to provide for its own parking. And this isaccomplished by setting back buildings and paving theirfronts. While doing this, sidewalks have been incorporatedinto the parking lots, making the environment a very dan-gerous one to the pedestrian.Sidewalks that are not affected by parking lots, lack main-tenance, shade and incentives to the pedestrian.

Bridge Road: Proposed Changes (Right):

- Head-in parking needs to be removed and replaced by on-street parallel parking (22’ x 8’) along Bridge Road, andangled parking along side streets.- Bump-outs should be incorporated into the streetscape every three to five parked cars. This will provide an oppor-tunity to plant trees, add street furniture, and reducepedestrian crossings. It will also contribute to the reduc-tion of speed and the creation on a sense of enclosure, allnecessary factors to create a pedestrian friendly environ-ment.

Left: Different views of sidewalks along Bridge Road. Top Right: proposed changes to theexisting section. Right: Different views of sidewalks that contain all the elements to beincorporated along Bridge Road.


T R E A S U R E C O A S T R E G I O N A L

P L A N N I N G C O U N C I L


19SIDEWALKS: A1A

A1A: Existing Condition (Left):

- Extremely narrow sidewalks, frequently interrupt-ed by potted plants, store doors, electric and light-ing poles, signs, trash containers and merchandise.This frequently forces pedestrians to walk on the street.

- Few awnings or protection from sun and rain.- Moving traffic directly adjacent to narrow side-

walk.- Parking on opposite side of retail, forcing pedes-

trians to constantly cross a vehicular way to access the different stores.

A1A: Proposed Changes (Right):

- Trash receptacles, planters and other movable ele-ments should be removed from the sidewalk and relocated where the sidewalk widens or along the edge of buildings (see figure top right).

- Awnings should be incorporated wherever possi-ble

- Pavers or other similar finishes are a nice addition to the sidewalk.

- Trees should be planted. Bump-outs should be used as planters. These should occur every three to five parking spaces. These can also be used as locations for benches, trash receptacles and spe-cial signs.

Above: A one-sided main street facing a railroad line. Sidewalks are proposed onboth sides of the rod. In this case, parking is parallel and on both sides of the road,shielding pedestrians from moving traffic.




20STREET LIGHTING

Do Not:- Use cobra head lighting. Cobra-type lights are too tall for a pedes-trian environment and their lack of design and care for details isevident.- Install fixtures at a height greater than 12’. If they are too high, theyproject light further, which is convenient for automobiles, but do notgive adequate light to the area immediately around it. The higher thelamp, the greater the unlighted area at its base.

Do:Install light fixtures on both sides of the road. Streetlights contributeto the quality of the street. Simple glass globes set on simple darkolive or black poles, about nine feet tall are ideal. Globes should notbe translucent during the day.These fixtures not only functionally light the street, they mark thecenter, and a line for the eye to follow, both day and night. Theyshould be placed at regular intervals, at a height that is convenient forthe eye to follow (9’ to 10’).




SIGNAGE 21

Attached Elements:

Storefront glass shall be clear, as any saturation will cause the display tobecome invisible behind the resulting reflection.Do Not:- Permit reflective (mirror) nor colored glass on any shopfront or windows. Itis important not to break this rule when office space is a permitted groundfloor use. The lack of transparency of reflecting glasses negatively impacts theperception of security in any given area.- Allow blade signs to exceed 4 square feet in area (including mounting hard-ware.- Allow translucent blade signs

Do:

- Request uniform shopfronts, doors, signage and lighting design.- Apply postal number anywhere in the entrance area.- Permit one two-sided blade for each business with a door on the sidewalklevel. The blade sign shall be securely affixed to the façade or storefront andmay project over the sidewalk, so long as it does not interfere with pedestrianflow..- Allow a sign band 60% of the width of the building frontage, with a heightnot to exceed three feet. The sign shall be integrally designed with the buildingor the associated storefronts in material and paint colors. The sign band mayonly be externally lit.- Permit logo including the name of the store inscribed on the storefront glass - Allow inscription on awnings, so long as it doesn’t exceed 6” in height.

Refer to Hobe Sound Mixed Use Overlay zoning for additional regulationsregarding signage.

BUILDING TYPES 26

Single Family House

- Different types of Single Family houses can be identifiedaccording to placement and lot size. Row or town houses,side-yard, rear yard and wide lot house are four of themost commonly found in traditional neighborhoods.- Rowhouses are usually sited at the front of a narrow lot( 16 to 25 feet), have no side setbacks and share one ormore side walls with neighboring structures. Entrances aregenerally elevated from the sidewalk to provide privacy.Porches and stoops are common elements of this type.Parking is generally provided in an outbuilding that is

accessed from a rear alley.- Sideyard houses are usually one room wide, positioned towards the frontand side of the lot with porches generally wrapping around the front andside that faces the open yard. Parking is generally provided in an outbuild-ing that is accessed from a rear alley.- Rear yard and wide-lot houses are generally suited for larger lots and arelocated at the edge of town. The first is generally set back between 5 and15 feet from the property line, may have a porch that encroaches on thissetback, and has a yard in the rear. Wide-lot houses have yards on all foursides and may have out-buildings. Porches could be present along frontand rear elevations or wrapping around the entire structure.

Desirable Non-DesirableYes: Ground floor is ele-vated, good façade articu-lation achieved with frontporch and window place-ment. Good relation tothe public spaceNo: Garage and drive-ways are the predominantelement, leaving thepedestrian on a secondaryplane.

Yes: Private ground floor,public rooms face thestreet creating a sense ofsecurity.No: Garage is main (andonly) feature. Additiona-lly, a large driveway sepa-rates the building from thestreet, again prioritizingthe automobile.

Yes: Wide lot house w/twolevel front porch. Goodconnection to the streetparking in rearNo: House isolated by wallcreating an unsupervisedpublic realm.

BUILDING TYPES 27

Rear Yard House

- Rear yard houses are suitable on all residential streets. Lot sizes (widths) for these types ofhomes generally vary between 35 to 150 feet, with larger homes being closer to the edges ofthe town, along special natural or man-made features and amenities (canals, golf courses, pre-serves, etc.). Maximum lot width is not limited to 150 feet, but lot widths should be suchthat, when combined, do not form blocks that are larger than 600 feet in any of its sides.

- Rear house, single family buildings should house one family.

- Garages should be recessed from the front of the house, and, when an alley is present, theyshould be located in the rear of the property and accessed through the service alley.

- Garages may have up to two stories, to allow for “granny flats” above the space used forparking. This flat serves as a guest house, or a rental apartment. These flats provide afford-able housing within any given neighborhood, as well as help set-off the cost of the homes’smortgage. The fact that this rental unit is directly adjacent to the landlord’s home, assuresproper keep and surveillance of the tenant.

BUILDING TYPES 28

Side Yard House

- Side yard houses are located close to the street and against one side of the property. Theyare usually one to two rooms wide on the side facing the street. Sideyard houses are suitableon all residential streets. Lot sizes (widths) for these types of homes generally vary between35 to 50 feet. This type is more urban in character, and can be sited along any neighborhoodstreet, around parks, and in locations that call for higher densities. Maximum lot width is notlimited to 50 feet, but lot widths should be such that, when combined, the built protion ofthe block is larger than the open space along it.

- A side porch facing the sideyard is mandatory.

- Side yard houses are to be occupied by one family.

- Garages should be recessed from the front of the house, ideally in rear of the property andaccessed through a service alley.

- Garages may have up to two stories, to allow for “granny flats” in the case of a secondstory.

Row House

- Rear yard houses are sited in the front of the lot, with little or no setback from the proper-ty line. Lot sizes (widths) for these types of homes are very narrow, between 16 to 30 feet.Side walls are common walls shared with neighboring structures. These homes are locatedcloser to teh center of the town, arond neigbhorhood or town centers, along roads that carrya larger amount of traffic as well as close to commercial areas.

- Town house buildings should house one family.

- Garages should be should be located in the rear of the property and accessed through aservice alley.

- Expression lines are required between the first and second floor of the front façade if it isvisible from the street.

SECTION IVARCHITECTURE AND CHARACTER




FLORIDA VERNACULAR ARCHITECTURE 32

General Characteristics

- Roofs of the primary structure are typically gabled with a slope between 6:12 and 12:12

- Roofing materials consist of metal, standing seam or "V" crimp, asphaltic shingles or wooden shakes.

- Roof overhangs are typically deep, between 2'-4', and have exposed rafter tails. Fascias on the gabled ends are deeper than those exposed along the running cave edge.

- When attic spaces are desired, they are vented at the gable ends underneath the ridge and/or where the rafters meet the wall along the running cave edge.

- Generally, the massing of the Florida Wood Vernacular buildings is vertically proportioned and 2 stories.Where possible roof rafters should be exposed to the interior to allow for greater interior volume on the second floor.

- The exterior finishes are almost always horizontal wood lap-siding. The siding should have between 4"-6" exposed to the weather and is terminated with vertical corner boards at building edges. Other siding mate-rials like wood-plank are acceptable.

- Doors and windows are vertically proportioned with wooden surrounds and sills. Horizontally propor-tioned openings are made of a grouping of vertical windows. Windows are usually double-hung with no light divisions in the top or bottom sash.

- Porches are obligatory and in many cases wrap around the front facade and continue at some length along the side facade. The porch roof is supported by posts which are placed to create a vertical or square open-ing between them. Porches in this genre are typically quite deep and occupy a large percentage, if not all,of the ground floor elevation. The porch roof may be of a different slope than that of the primary build-ing however detailing and overhangs should be consistent.

- The entire Florida Wood Vernacular building sits on a continuous, typically skirted, base. The base actually conceals a crawl space to allow for access and ventilation to the underside of the building.

- Other Architectural styles which could be considered in this genre include Victorian, "Carpenter Gothic", Cracker, and Shingle styles.

ARCHITECTURE: MEDITERRANEAN REVIVAL 36


- Roofs of the primary structure can be hipped, gabled, or a combination of both. Roof slopes are some-what shallow and are generally sloped between 3:12 and 6:12.

- Roof materials consist of barrel tile, Spanish "S" tile, or flat concrete tile.

- Roof overhangs can vary from being deep to having no overhang at all. When deep overhangs do exist,they are typically supported by sizable wooden brackets. Roofs that do not have an overhang are usually treated with a molded cornice.

- The Mediterranean Revival house is typified as ornate, asymmetrical, and eclectic. It is not uncommon to have multiple levels, multiple interior and exterior spaces, and even multiple buildings Building mass-ing tends to be irregular with a variety of shapes and heights however, the appearance of solidity and permanence is critical.

- Exterior finishes are almost exclusively stucco and colored with great richness, variety, and multiple methods of application. Brackets, balconies, porches, shutters, and other elements are usually wood or iron. The prolific use of arched openings and windows is also a prominent characteristic.

- Windows and doors are of vertical and/or square proportions with the occasional round, oval or orna-mental window. Openings for doors and windows are deep and cast deep shadows as well as give the impression of thickness and solidity. Windows do usually have divided lights and are commonly double-hung, casement, or jalousie. Window and door surrounds, when they exist, are made of stucco or stone.

- The attached porch is a common element as are balconies and courtyards. Loggias, a porch not attached but located within the volume of the building, are very common and may even serve as outside circulation between rooms.

- Columns, posts, wooden and masonry balustrades, brackets and various ornamentation are all very common elements within this genre. Columns may be rounded, twisted, or detailed as squared masonry piers. Although all of these elements are compatible, it is the delicate composition of a few of them that creates the successful Mediterranean Revival house.

- Variations of this style could include Mission or Santa Fe.

MEDITERRANEAN REVIVAL ARCHITECTURE: DETAILS 42



- Roofs of the Anglo-Caribbean house are made of wood or asphalt shingles,metal, or slate. Roofs slopes are between 4:12 and 8:12 and are typically hiproofs.

- Roof overhangs are typically quite deep with exposed rafter tails and thineaves. Often the overhang will kick out from the beam at a shallower roofslope to give the appearance of a canted roof. This allows for a steeper roofslope and a deeper overhang without covering too much of the elevation withroof.Brackets can be used at the overhang but are not used as extensively as with

the Florida Bungalow house..

- The Anglo-Caribbean house is a hybrid of Wood Vernacular and Spanish orMediterranean detailing and materials. Masonry or stone is used on the groundfloor while wood framing and siding are used on the second floor. The facadecompositions are typically symmetrical with long covered balconies and porch-es. Ground level masonry columns or piers support second level woodenposts.

- Exterior finishes are almost exclusively lower level stucco and upper level sid-ing. Colors tend to be subtle with an emphasis on natural materials and earthtones. There is the extensive use of balconies supported by brackets, two storyporches, louvered openings and shutters. Detailing and ornamentation is very simple and tectonic in its usage.

- Windows and doors are of vertical and/or square proportions. Openings fordoors and windows are deep and cast deep shadows as well as give the impression of thickness and solidity. Windows can have divided lights, single lights, and may borrow lightconfiguration from the Florida Bungalow or Craftsman languages. Windows are most commonly double-hung or casement. Window and door surrounds, when they exist, are madeof stucco, stone, or wood.

- The front porch is a common element and typically supports a second story balcony and is thereby under the primary roof. Loggias, like in the Mediterranean Revival, can befound on either the first or second story. Porches are augmented by bracketed second floor balconies.

- Columns, posts, wooden and masonry balustrades, and brackets are all very common elements within this language. Columns are either smooth and round, or can be detailed assquared masonry piers. The most prominent feature of the Anglo-Caribbean house is the clear distinction between the first and second floors; between the massive and the deli-cate, between masonry and wood.

ARCHITECTURE: FLORIDA BUNGALOW 51


- Roots of the Bungalow are predominantly gabled with shallow slopes 3:12 to 6:12.

- Roofing materials are mostly asphalt shingles although metal is appropriate.

- Deep overhangs are characteristic as well as exposed rafter tails and support joinery. Typically at a gable'send there are substantial wooden support brackets.

- The Florida Bungalow house, like the Mediterranean Revival, is eclectic in its origins and detailing. Generallythe house is one or one and one-half stories tall and maintains a low profile. It is typically moderate in sizeyet delivers a prominent street presence with its porches and detailing.

- Exterior finishes are primarily wood and masonry. Although stucco is a common wall finish, variations ofwood siding and shingles give the bungalow its true Craftsman aesthetic. Masonry and stone are used exten-sively for a building's base, steps, and the pedestal for porch columns. Wooden brackets, railings, balustrades,and tapered columns are all very common elements.

- Windows and doors are square or vertically proportioned and are almost exclusively double-hung. Sharingcharacter with the Craftsman or Prairie style, windows will typically have multiple vertically divided lightsMany times the top sash alone will be divided with the bottom sash remaining whole. Window and door sur-rounds are wood and can be quite elaborate.

- Front porches are a very important element in the whole Bungalow composition. In addition to their use-fulness as an important neighborhood device, the front porch is the opportunity to articulate and ornamentan otherwise straightforward box. The porch, when it is the full width of the house, can share the roof ofthe primary structure. When under the primary roof, typically shed or "sleepy" dormers are provided to addlight into the roof space. This condition occurs when the ridge of the roof is running parallel to the Street.

- The Florida Bungalow house sits on a continuous stone or masonry base which becomes an integral anddefining element throughout the facades. Rarely are rounded columns used. Tapered wooden posts or mason-ry piers are the most common vertical support members.

- Variations of this style could include Prairie, Craftsman or "Stick" style.
