11.2.1.A.

Development planning within the PMUV begins with the creation of the Regulating Plan (see Figure 2-1). The Regulating Plan establishes the general location, size and type of neighborhoods, as well as other important elements that define the overall structure of the proposed development. The Regulating Plan is a regulatory document. Development within the PMUV shall be consistent with the Regulating Plan.

11.2.1.B.

The Regulating Plan shall clearly illustrate the following:

1.

The Primary Urban Services Boundary (PUSB);

General Standards.

1.

Precedent images are for illustrative purposes only to demonstrate the intent of the standards. They are provided as examples, and shall not imply that every element in the image is permitted.

2.

The allocation of Transect Zones and required Civic Open Space by percentage are based on gross area allocated transect zones within each neighborhood. Gross area transect zone allocation within neighborhoods does not include wetlands or areas designated with the T1 Transect.

3.

Minimum residential density is measured for the total net acres allocated to each Transect Zone within each neighborhood. The net acre calculation does not include Right-of-Ways.

4.

Accessory Dwelling Units do not constitute a separate unit for the purpose of calculating residential density.

11.3.13.A.

Overview.

Civic spaces are those areas that serve a public function or are dedicated to preserving and enhancing the public well-being. These areas may contain passive or active civic uses dedicated to arts, culture, education (including public and private schools and colleges), recreation, government, transit, and municipal parking. Reflecting the diverse nature of this Transect Zone, it is divided into two categories: Civic Open Spaces and Civic Buildings. It is difficult to determine beforehand the multiplicity of potential uses that may occupy these Civic spaces overtime. Therefore, greater design flexibility shall be given to these sites with key development standards and guidelines, and buildings are to be subject to a greater degree of design review on a case-by-case basis.

Figure 3-5: Illustrative example of buildings and site arrangement in the Civic Zone.

11.3.13.B

Examples.

 11.3.13.C.

Civic Open Spaces.

(a)

General

Civic Open Space in the form of parks, greens, squares, plazas, playgrounds, pavilions, or recreational fields shall be located in each neighborhood at a minimum area greater than or equal to 5 percent of all land assigned a Transect Zone within the neighborhood.

(b)

Guidelines

Heightened attention shall be paid to the quality of landscape design and function according to the following principles:

1.

All designated Civic Open Spaces shall be shall be accessible to the public.

2.

The landscape design shall support and express environmental, cultural, and historical attributes.

3.

The landscape design shall promote connection with nature, social interaction and mental restoration.

4.

Views of natural features shall be preserved or maximized.

5.

The landscape design shall promote connection to surrounding neighborhood resources, amenities and services, and provide for optimum accessibility, safety and way-finding.

6.

Stormwater management improvements shall be integrated with the final landscape design as aesthetically and visually pleasing design elements.

7.

Whenever appropriate, landscape design shall promote sustainability awareness and education through interpretive signs, demonstrations and other forms of interpretation.

The appropriate arrangements for Civic Open Spaces are described to the right and are permissible within proximity of the Transect Zones indicated in Table 3-4.

(c)

Civic Open Space Types

Expand

Park
	A natural preserve available for unstructured recreation. A park does not need to be fronted by buildings. Its landscape shall consist of paths and trails, meadows, waterbodies, woodland, recreational fields, and open shelters, all naturalistically disposed. Parks may be lineal, following the trajectories of natural corridors.
Green
	Available for unstructured recreation. A Green may be spatially defined by landscaping rather than buildings fronting it along the edges. Its landscape shall consist of lawn and trees, naturalistically disposed.
Square
	Available for unstructured recreation and public gatherings. A Square is spatially defined by building Frontages. Its landscape shall consist of paths, lawns and trees, formally disposed. Squares shall be densely shaded and provide seating. Trees and shrubs shall be of sufficient quantity and located as to define a specific geometry of open space and shall promote security by allowing visibility through all areas.
Plaza
	Available for public gatherings and outdoor markets. A Plaza shall be spatially defined by building Frontages. Its landscape shall consist primarily of pavement. Plazas should use pervious pavers, where feasible. Trees are optional.
Playground
	Designed and equipped for the recreation of children. A playground should be fenced and may include an open shelter. Playgrounds may be interspersed within residential areas and may be placed within a Block. Playgrounds may be included within parks, greens, and squares.

11.4.l.A.

This Division establishes standards for lots and individual buildings within the PMUV. Topics including Building Types, Accessory Units, Building Standards, Façades, Frontage Types, and site standards.

11.4.2.A.

A mix of residential building types creates neighborhoods which allow a diversity of ages and incomes, and permit residents move or downsize their homes without having to move away. Multi-generational neighborhoods create strong social networks, avoid concentrations of poverty or wealth, and lead to safer communities. The residential building types permitted within the PMUV are described textually below and then through illustrations.

1.

Mixed Use Building/Block: This type features shop fronts on the ground floor with space designed to accommodate residential or office on the floors above. Mixed-use buildings often have a parapet with a pronounced cornice.

2.

Apartment Building: This type contains multiple units accessed via a main entrance on the primary frontage. Units may be for rent, or for sale as a condominium.

3.

Mansion Apartment: This multi-family type is designed to look like a large single family house but in fact contains several units. This type usually features a front porch to help it blend in with adjacent single family types.

4.

Live/Work Unit: Buildings or structures used jointly for commercial and residential purposes where the residential use of the space is secondary or accessory to the primary place of work. The commercial function may be anywhere in the unit. It is intended to be occupied by a business operator who lives in the same structure that contains the commercial activity or industry.

5.

Townhouse: This is a single family attached building type. Adjacent dwellings may share a party wall with another unit of the same type and occupies the full Frontage Line. Row Houses typically feature a private yard or patio between the main structure and the rear out-building.

6.

Duplex House: This is an attached single family house type where only two units share a party wall. The duplex can easily blend in with single family houses.

7.

Courtyard House: A dwelling that occupies the boundaries of its Lot while internally defining one or more private patios

8.

Sideyard House: A dwelling that is zero lot line on one side and occupies one side of the Lot with a Setback on the other side. This type can be a single or duplex depending on whether it abuts the neighboring house.

9.

Cottage: The smallest of the single family house types and generally has a small front porch.

10.

House: This single family house is generally two stories in height and often contains habitable attic space. Often shared with an Accessory Building in the back yard.

11.

Villa: This large single family house type is generally two stories in height and often contains habitable attic space. The type is typically located on the edge of a neighborhood and is sited on a very large lot of rural character, often shared by one or more Accessory Buildings.

12.

Accessory Dwelling Unit: Also referred to as accessory apartments, second units, or granny flats—are additional living quarters on single-family lots that are independent of the primary dwelling unit. The separate living spaces are equipped with kitchen and bathroom facilities, and can be either attached or detached from the Principal Building.

13.

Farm Labor Housing: A single family house type intended to be occupied by an occupant(s) who works on the same or adjacent property that contains the agricultural activity. Accessory buildings strictly for vehicular use are not permitted. Accessory buildings such as barns, sheds, and greenhouses are permitted.

14.

Residential Convertible to Retail: A flexible mixed use or live/work building type where the ground floor is initially occupied with residential units that can later be converted to commercial use as the market matures.

11.4.3.A.

Front and Backs.

Buildings and lots have fronts, sides, and backs and how these relate to one another forms neighborhood character.

1.

Front Façades, the main presentation faces of buildings and lots containing the Principal Entrance, should face the Public Realm.

2.

The backs of buildings and lots, which are the private or service side, should face mid-block and be screened from view. Backs of buildings or lots shall not abut the Frontage Line.

3.

Sides of buildings and lots may face either the Frontage Line or be concealed mid-block.

4.

Thoroughfares, with the exception of Alleys, should be faced with the fronts or sides of buildings and lots.

5.

Alleys and mid-block parking areas should be faced with the backs or sides of buildings and lots.

6.

The backs of buildings and Lots shall not be across from, or adjacent to, a Civic Open Space.

7.

The backs of buildings and Lots shall not face Civic Building Frontages.

11.4.3.B.

The table below outlines the range of relationships between the fronts, sides, and backs of buildings/lots.

11.4.4.A.

One Principal Building and one Accessory Dwelling Unit may be built by right on each single-family lot, including townhomes, as permitted by Table 3-3.

1.

Accessory Dwelling Units shall not exceed 900 square feet in Habitable Space, excluding parking.

2.

Each single-family lot may accommodate one Accessory Dwelling Unit in the T3, T4-R, T4-0, and T5 Transect Zones.

3.

Accessory Dwelling Units shall be limited to 2 Stories, including ground floor parking. These units are not computed towards overall density or unit calculations.

(Ord. No. 1235, Pt. III, 11-12-2024)

Buildings shall comply with the following:

11.4.5.A.

Heights.

General building height information is provided below. Refer to the Transect Standards for setback and height information specific to each Transect Zone.

1.

A Story is that part of a building contained between any finished floor and the floor or roof next above. Habitable attics (space within the roof structure) are permitted and are not considered Stories for the purpose of determining Building Height.

2.

Stories may not exceed 14 feet in height from finished floor to finished ceiling, except for a first floor commercial function, which shall be a minimum of 12 feet and may be a maximum of 25 feet. A single floor level exceeding 14 feet, or 25 feet for ground floor commercial, shall be counted as two (2) Stories. Mezzanines extending beyond 33% of the floor area shall be counted as an additional Story.

3.

Building Height shall be measured as the vertical distance between (1) the lowest permissible elevation above the existing grade which complies with finished floor elevation requirements as established by flood maps, the Health Department, or building code, along the front of a building and (2) either the highest point of the coping of a flat roof, the deck line of a mansard roof, or the mean height level between eaves and ridge for gable, hip and gambrel roofs.

4.

Building Height is limited to 40 feet and four-Stories, with the following exceptions:

(a)

Steeples, spires and belfries on Places of Worship provided such structures do not exceed 60 feet in height, are part of a principal building, and are not used for human occupancy.

(b)

Roof structures including chimneys, parapet walls not over four feet high, tanks and supports, elevator machinery or shafts, penthouses used solely to enclose stairways and air conditioning equipment, provided that such structures do not exceed ten percent of the roof structure measured on a horizontal plane, are not used for human occupancy, and provided that the use of such structure does not exceed the district height requirements by more than eight feet.

(c)

Non habitable structures used exclusively for agricultural or industrial processes or for protective and emergency service uses may exceed the height limitation pursuant to Sec. 3.14 Martin County Land Development Regulations.

11.4.5.B.

Small Footprint Towers/Cupolas.

These features, as well as steeples, spires and belfries on Places of Worship, are designed to extend above the roofline, and are generally intended to be visual landmarks. They are commonly placed to terminate vistas.

1.

Small Footprint Towers/Cupolas with a footprint smaller than 30 feet by 30 feet may extend above the established Transect Zone Building Height, but shall not exceed the 40 foot height limit.

Figure 4-2: Small Footprint Tower and Cupola

11.4.5.C.

Principal Entrances.

The Principal Entrance of every Principal Building must be located along the Primary Façade and directly face a Street or Civic Open Space. Additional building entrances are permitted.

11.4.5.D.

Entry/Exit Doors.

Public entry and exit doors which swing outward shall be recessed into the façade a minimum of three feet where the sidewalk abuts the building.

11.4.5.E.

Window and Door Openings.

1.

Window and door openings in masonry facades should express a structural lintel above to express the conveyance of building weight. A similar method using wood trim can be used on wood-clad facades.

2.

Windows and doors shall be vertically proportioned or subdivided to appear vertical.

11.4.5.F.

Columns/Posts.

1.

The proportion of structural elements such as columns or posts should be appropriate to the weight they appear to be carrying.

2.

Columns and posts shall not be spaced further-apart than they are tall.

11.4.6.A.

Material Changes.

1.

When materials are combined on a building façade horizontally, heavier materials should occur below lighter materials.

2.

For buildings of three stories, the ground floor should be differentiated from those floors above in order to reinforce the pedestrian space.

3.

Changes from one material or color to another along the horizontal direction should occur at "inside corner" transitions.

4.

Changes in material or color along the vertical direction should occur at a hard-edge "bump-out" transition which gives materials a surface to terminate into.

5.

Façades with an overabundance of different materials or colors are generally discouraged.

Figure 4-3: Façade transparency requirements for buildings with shopfront.

11.4.6.B.

Wide façades.

1.

Building facades longer than 50 feet shall be varied with at least one change of architectural expression. These changes in expression may be a vertical element running from the ground plane to the roof, a change in fenestration, color, or texture, or a break in building facade plane or roof line. These changes may be subtle or significant, but should soften the visual effect of very wide buildings, especially those directly across the street from narrower buildings. Strive for an appearance of authenticity when subdividing a large facade into multiple smaller facades resembling distinct buildings.

Figure 4-4: Façade transparency requirements for buildings without shopfront

11.4.6.C.

Façade Transparency.

All building Façades which face onto a Street or Civic Open Space shall meet the minimum transparency requirements outlined herein. The percentage of transparency per Story shall be calculated within the area between finished floor and finished ceiling and shall be a total percentage of doors and windows along that portion of the façade.

1.

Buildings with Shopfront

(a)

Minimum building façade transparency for ground Story: 70 percent and should allow a view of at least five 5 feet of interior space.

(b)

Minimum building façade transparency for upper Stories: 40 percent.

2.

Buildings without Shopfront

(a)

Minimum building façade transparency for ground Story: 30 percent.

(b)

(Ord. No. 1235, Pt. III, 11-12-2024)

11.4.8.A.

Flat Roofs.

1.

Flat roof structures shall be bounded by an articulated parapet design which provides a noticeable "cap" to the building.

2.

The parapet on a single-story façade should express at least six inches in overhang depth, and be at least 18 inches tall. Parapet overhang depth and height for taller facades should be increasingly larger.

11.4.8.B.

Sloped Roofs.

1.

Sloped roof structures are encouraged to maintain a pitch between 6:12 minimum and 12:12 maximum for all primary roof areas (not including dormers, entry canopies, or similar accessory elements.)

2.

Roof overhangs are encouraged to be at least 6 inches deep.

3.

Dormers and Gables are encouraged along front facades to help maintain a prominent façade, reduce the scale of long runs of roof, and divert rainwater from entry areas.

11.4.9.A.

Service Areas & Loading Docks.

4.

Trash and recycling dumpsters or similar collection areas shall be located in the rear or to the side of buildings and screened from view from adjacent public Right-of-Ways, properties, and pedestrian walkways (not including Alleys).

11.4.9.B.

Mechanical Equipment.

1.

For the purposes of these standards, mechanical equipment includes any heating, ventilation, and air conditioning (HVAC) or electrical machinery as well as air compressors, hoods, mechanical pumps, exterior water heaters, water softeners, utility and telephone company transformers, meters or boxes, garbage cans, storage tanks, generators, electric vehicle (EV) chargers, geothermal wells, and similar elements.

2.

If mechanical equipment is located at-grade, and is visible from an adjacent street or sidewalk, it shall be screened by a fence or Streetscreen.

3.

All mechanical equipment or penthouse screening placed on a roof shall be set back from the roof line by a distance at least equivalent to the height of the screening in order to minimize visibility from surrounding streets.

Within the T5 Center and SD-W Zones, some automotive-oriented uses and large footprint buildings may be provided to serve the daily needs of residents. The following criteria shall be used to ensure these uses and buildings do not detract from the overall walkability of the neighborhoods.

11.4.10.A

Gas Stations.

1.

A ground-floor shopfront shall face the Primary Street and define the Frontage of the lot. All pumps, parking, and drive-through areas must be located behind the shopfront building toward a mid-block location.

11.4.10.B

Drive-through.

1.

A ground-floor shopfront shall face the Primary Street. All parking shall be located in the rear and accessed from an Alley when present. Drive-through windows shall be located to the side or rear of the building and accessed from mid-block or Alleys, where existing. Where no mid-block or Alley access exists, access from a Secondary Street frontage is permitted, but shall not substantially disrupt pedestrian activity or surrounding uses

11.4.10.C

Large Footprint Buildings

Large Footprint Buildings are those with footprints greater than 30,000 sq. ft. Examples may include a grocery store, large-format retailer, or theater. Lots may exceed the dimensions set in the Transect Zone Standards provided such buildings comply with the following provisions:

1.

Habitable frontages (as part of the building or a separate liner building) that provide doors and windows facing the Public Realm shall be provided along Façades that face Civic Uses or Streets.

2.

To encourage use by pedestrians and decrease the need for solely auto-oriented patronage, Large-Footprint Buildings must reinforce the urban character of the neighborhood and shall therefore continue a connected system of walkable blocks/street frontages (including sidewalks and street trees) through the site as part of the design of parking and drive aisles.

3.

Building footprints may not be larger than a single block.

4.

Loading docks, service areas, and trash disposal facilities shall not face streets or Civic Uses.

The purpose of the Thoroughfare Standards is to provide guidance to create an interconnected network of streets that can accommodate all modes of travel, including vehicular, pedestrian, and bicycle. The function of streets within the PMUV is to handle multimodal forms of traffic by providing a memorable experience by persons using the Street network. The streets will work together with the trails network to provide multiple options for moving throughout the neighborhoods and around the PMUV The function of each street will guide the design in concert with its context. The context is determined by the character of its Transect Zone.

The location, Street type, and hierarchy of proposed new or improved corridors are identified in the Streets Atlas (Sec. 11.5.7). Typical street sections illustrating the key characteristics of each proposed new or improved street are provided in the following section. The conditions illustrated in the typical sections may be interrupted for intersections, bump-outs, central greens, or other traffic calming devices depending on the context details of the final neighborhood designs.

On each parcel that has multiple street frontages (e.g., corner lots), the street hierarchy will determine the highest priority (Primary) street frontage, where the Front Build-to-Zone or Setback shall apply. Along the lower priority frontages, the Side (Secondary) Build-to-Zones or Setbacks shall apply. The designated street hierarchy is as follows:

(Ord. No. 1235, Pt. IV, 11-12-2024)

The precise location and alignment of new streets may be adjusted to allow flexibility in the design of the site plan; however, the intended purpose and network connectivity of each new street shall not be compromised. Proposed improvements to Citrus Boulevard shall be permitted by Martin County.

11.5.3.A.

Street design.

The design of new streets and modifications to existing streets shall adhere to the following requirements:

1.

Some dimensional flexibility is permitted for street types to account for varying Right-of-Way widths, however they shall be designed to have all the basic functional characteristics including roadway width, on-street parking/Curb side Flex Zones, sidewalks, trails, street trees, and landscaped areas shown for their type, and be appropriately sized for the Transect Zones in which they are located.

2.

New street types (with new sections) shall be permitted with approval by the Settlement Architect and Martin County. The Martin County Engineer may approve new street types administratively without requiring an amendment to this Article.

3.

Each Neighborhood shall demonstrate appropriate provision for street connectivity and integration with adjoining neighborhoods. Connections to future development is required. When a Sub-district Site Plan, consisting of one or more neighborhoods, is submitted for approval, the street network contained in those neighborhoods should connect to stub-outs of adjacent neighborhoods or other rights-of-way that form the edge of the neighborhood(s).

4.

All non-pedestrian only Streets shall accommodate two-way traffic with the exception of streets adjacent to squares and plazas and Alleys, which may have 1 travel lane with one-way traffic.

5.

All Streets shall connect to other Streets, except that dead-end streets with cul-de-sacs or T-turnarounds may be permitted only when necessitated by environmental constraints, provided the Street terminus provides adequate maneuverability for public services.

6.

Curbside Flex Zones replace the traditional on-street parking lanes with zones for a variety of uses, depending on the adjacent Transect Zone, on the following Street Types: Citrus Boulevard side access lanes, Urban Streets, Workplace Streets, and Main Street. The zones can vary along the length of the curb and/or throughout the time of day or year. Permitted zones may include: parking, transit stops, ride share passenger pick-up/drop-off, delivery, vendors, and shared-mobility stations.

7.

Where possible, there should be parking lanes/Curbside Flex Zones on one or both sides of a Street, depending on need.

8.

On-street parking lanes/Curbside Flex Zones shall not be closer than 25 feet to intersections measured from the curb line.

9.

All streets shall have sidewalks which are a minimum width of 6 feet, and have a continuous unobstructed path of a width no less than 60 inches. This path shall be unobstructed by utility poles, fire hydrants, benches, street signs, or any other temporary or permanent structures. A shared-use path having a minimum width of 8 feet may take the place of a sidewalk.

10.

At-grade pedestrian crossings should be used where possible, eliminating the need for curb ramps. Bollards should be used at such crossings for pedestrian and vehicle separation.

11.5.3.B.

Curb Radius.

Several walkability benefits can be gained by decreasing the radius of curbs at intersections. These benefits include the following: decreased crossing distances for pedestrians, greater visibility of pedestrians by motorists, and traffic calming, enhancing safety for pedestrians.

Corner curb radius designs fall into two distinct categories: corners with and without on-street parking.

1.

Corners with on-street parking shall have curb radii of 15 feet maximum. The effective turning radius is larger than the curb radius when parking is present. Thus, the effective turning radius can be 30 plus feet when the curb radius is 15 feet.

2.

Corners without on-street parking require the curb radii to be similar to the turning radii, with the curb radius between 20 feet and 30 feet maximum.

3.

Curb radii may be larger, up to 40 feet, within the SD-W Transect Zone at larger intersections to accommodate the more frequent movement of large trucks.

4.

Curb radii may be smaller, 9 feet to 15 feet, for Alleys.

11.5.3.C.

Alleys.

A continuous network of Alleys is desirable to serve as the primary means of vehicular ingress to individual lots. Such networks are mandatory in the T5, T4-0, T4-R, and T3 Transect Zones.

1.

Alley entrances should align so as to provide ease of ingress for service vehicles.

2.

Alley entrances shall not face Civic Open Spaces or Civic Buildings.

3.

Internal deflections or variations in the Alley network are encouraged to prevent excessive or monotonous views of the rear of structures resulting from long stretches of Alleys.

4.

Alleys should meet streets with a mountable gutter pan, allowing the sidewalk to continue uninterrupted across the Alley pavement. The use of curb cuts, ramps, and marked crosswalks should be avoided for Alleys.

11.5.3.D.

Intersection Design/Size.

While intersection design shall accommodate larger vehicles, the safety of pedestrians and bicyclists shall be the highest priority.

1.

The majority of intersecting streets shall meet at approximately a 90-degree angle. Angles of intersection less than 60 degrees should be avoided.

2.

Offset intersections in close proximity to one another (220' for Urban Street Types, 150' for other Street Types) are prohibited.

3.

The use of auxiliary turn lanes at intersections for traffic movement shall be carefully weighed against the impact to pedestrian and cyclist movement at the intersection, and the use of such lanes shall not be determined by traffic analysis alone. The final decision on whether an auxiliary turn lane is required shall be made by the County Engineer with agreement from the Settlement Architect.

4.

Pedestrian and bike crossing infrastructure shall be provided across all intersection approaches, including high visibility crosswalks, sidewalk ramps, and detectable warnings.

5.

Traffic signals shall be timed primarily for the convenience and safety of pedestrians and bicyclists.

6.

To the extent possible, pedestrian exposure to vehicles and crossing distances shall be reduced through the use of refuge islands, bump outs, and pedestrian signals.

11.5.4.A.

General Street Lighting Standards.

1.

All street lighting shall comply with the standards established in Sec. 11.6.4.A and Sec. 11.6.4.B Lighting Standards.

2.

A combination of pedestrian-scaled street light fixtures and intersection street light fixtures may be required to ensure a well-lit street and to establish a unifying element along the street. Pedestrian-scaled fixtures shall be used on all streets, except Alleys. Intersection-scaled lighting may be used in addition to pedestrian-scaled lights where necessary.

3.

Street lights shall be aligned with street tree placement (generally between 2.5 feet and 4 feet from the back of the curb). Placement of fixtures shall be coordinated with the organization of sidewalks, landscaping, street trees, building entries, curb cuts, signage, etc.

4.

The height of light fixtures shall be kept low (generally not taller than 15 feet) to promote a pedestrian scale to the Public Realm and to minimize light spill to adjoining properties. Light fixtures shall be closely spaced (generally not more than sixty (60) feet on center) in T4-R, T4-O, and T5 Zones and eighty (80) feet in the T3 and SD-W Zones to provide appropriate levels of illumination.

5.

Light poles may include armature that allows for the hanging of banners or other amenities (e.g., hanging flower baskets, artwork, etc.).

6.

All street lighting fixtures shall be full cutoff.

11.5.4.B.

Lighting Types And Configurations.

1.

The configuration of street lighting fixtures shall be appropriately chosen for the Transect Zone within which they are located as outlined in the table below. Flexibility shall be permitted to vary from strict compliance with this table to achieve logical uniformity of fixtures within a given thoroughfare segment or Public Realm.

2.

The Settlement Architect shall set a lighting pole and fixture standard for use throughout the PMUV prior to the approval of the first Neighborhood Final Phase Plan for aesthetic conformity and maintenance inventory. Any light pole or fixture to be maintained by Martin County shall be approved by the County Engineer.

1.

All street trees shall comply with the General Landscape Standards in Division 6: Site Development Standards.

2.

Street trees shall consist of shade trees with a minimum 3-inch caliper at time of planting. Other accent plants and trees are permitted in addition to the required street trees.

3.

Street trees shall be provided in a manner and at a spacing as defined by the Street Type standards.

4.

Street trees shall be planted in vegetated Planting Strips or Tree Wells with grates according to Street Types.

5.

Properly designed tree box filters to accept stormwater runoff are encouraged for stormwater quantity and quality mitigation, and shall count towards the street tree requirement as long as adequate maintenance access is provided and the street tree planted meets the requirements of this standard. See the National Association of Transportation Officials (NACTO) Urban Street Stormwater Guide and the Light Imprint Handbook for more information.

1.

Construction shall adhere to the Martin County Standard Details for Road & Site Construction and Public Facilities.

These general standards apply to all Transect Zones, unless otherwise noted, specifying standards that impact walkability and the quality of the Public Realm as well as parking requirements and the design of signage, lighting, landscaping, and utilities.

The intent of the parking standards is to encourage a balance between pedestrian-oriented development and necessary vehicle storage. The goal is to construct neither more nor less parking than is needed.

11.6.2.A.

Parking requirements.

1.

Parking shall be provided for each use based upon the minimum and maximum requirements outlined by use in Table 6-1: Automobile Parking Requirement Chart. Required parking quantities for a parcel may be modified by Warrant.

2.

Parking may be located on the same lot as the use it serves. Required parking may also be located on-street or in a common parking lot, provided the space is within 1/4 mile of the building's Principal Entrance. The required parking may be purchased or leased from a public or private civic parking reserve, the owner of which will manage the purchase or lease.

3.

Parking shall be located behind the Principal Façade of buildings whenever possible. Parking lots shall be masked from the frontage by a Liner Building. Streetscreens, Garden Walls, fences, or hedges are required along all rights-of-way without buildings to shield views to parking).

4.

Shared and Reduced Parking is encouraged in all Transect Zones for more efficient parking solutions. The amount of parking required is calculated by adding the total number of spaces required by each separate function in the Parking Requirement Chart and dividing by the appropriate factor from the Sharing Factor matrix. For example, the residential function requires ten spaces while the office function requires twelve spaces. Independently they would require twenty-two spaces, but when divided by the sharing factor of 1.4, they would require only sixteen spaces. When multiple functions share parking, the lowest sharing factor shall apply.

5.

Bicycle parking shall be provided in all Transect Zones per Table 6-3: Bicycle Parking Requirement Chart and subject to the two subsections below:

(a)

Anchors: All spaces provided shall include a metal anchor sufficient to secure the bicycle frame when used in conjunction with a user-supplied lock.

(b)

Location: Bicycle parking shall be located in a secure area covered from weather and shall be located as close to a building entrance as the closest on-site automobile parking space.

11.6.2.B.

Parking Access.

1.

Alleys, where proposed, shall be the primary source of access to off-street parking. Parking along Alleys may be perpendicular, diagonal, or parallel.

2.

Alleys may be incorporated into parking lots as standard drive aisles. Access between parking lots across property lines is also encouraged.

3.

Corner lots that have both rear and side access shall access parking through the rear. If no rear access exists, access to on-lot parking shall be provided from the side street.

4.

If no Alley or side street exists, then efforts should be made to demonstrate an attempt to gain access across neighboring properties.

5.

When access to rear parking must be directly from the Primary Frontage, driveways shall be located along the sides of the property lines and designed such that pedestrians crossing on sidewalks always have the right of way.

6.

The maximum width of vehicular driveways are provided in the Transect Zone Standards.

7.

Circular drives are prohibited except for Civic Buildings.

11.6.2.C.

Off-street Surface Parking.

1.

Minimum setbacks for off-street surface parking from all property lines are provided in the Transect Zone Standards.

11.6.2.D.

Garden Walls, Fences, and Hedges.

Garden walls, fences, or hedges may be located along Frontage Lines and other Lot Lines, or parallel with the Façades of buildings. When located along Frontage Lines, garden walls, fences, and hedges are called Streetscreens. Streetscreens may mask a parking lot from the Thoroughfare, provide privacy to a side yard, and/or strengthen the spatial definition of the Public Realm.

1.

Streetscreens shall be a minimum of 3 feet tall in all Transect Zones. Maximum heights shall be:

(a)

T3: 4 feet along Primary Frontage, 8 feet along other Frontages

(b)

T4-0 & T4-R: 4 feet along Primary Frontage, 6 feet along other Frontages

(c)

T5: 4 feet along all Frontages

Lighting fixtures shall be appropriately chosen for the PMUV There shall be consistency in creating a unifying scheme of illumination that is appropriate to the scale of the street and the level of evening activity.

2.

Lamp styles should not be mixed along any one particular block of a street.

3.

Light fixtures shall be downcast or low cut-off fixtures to prevent glare and light pollution.

4.

In order to conserve energy and reduce long-term costs, energy-efficient lamps shall be used for all Public Realm lighting.

11.6.4.B.

Light Levels.

1.

Lighting standards protect against glare, preserve the night sky, and reduce unnecessary energy use from over lighting. Rural zones tend to be darker, while higher levels of outdoor lighting may be more suitable in mixed use urban zones.

2.

It is the intent of this Article to follow Dark Sky provisions as established by the International Dark-Sky Association (IDA). All outdoor lighting within the Public Realm should be IDA-Approved fixtures.

3.

The standards in Table 6-4 maintain the desired general ambient light levels across the Transect. Light levels in the Civic Transect Zone shall be consistent with the intent of this Article and not contribute to excessive light pollution, as determined by the Settlement Architect.

11.6.6.C.

Parking Lot Landscape Standards.

The landscaping requirements in this section are intended to provide a set of standards toward reducing the visual impacts of large areas of pavement, improving the overall environment of parking areas by providing areas for shade and heat reduction, and enhancing the overall aesthetic appeal of parking areas.

1.

Developments with proposed parking areas of 6 spaces or more shall provide a minimum of ten percent of landscaped open space within the area designated for parking inclusive of any landscaped borders surrounding the parking lot. Use of the provided landscaped open space for vegetated stormwater quality management is allowed and encouraged.

2.

Surface parking lot entrances shall be landscaped with a combination of trees, shrubs, walls, and other landscape features. No trees, shrubs, fences, walls, or other landscape feature shall be planted in a manner to obstruct sight lines of motorists.

3.

The ends of parking aisles in surface lots that are more than 15 spaces in length shall incorporate landscape islands at either end of the row. Each island shall include at least one tree. Where the length of a parking aisle exceeds 25 spaces, additional landscaped islands shall be installed at regular intervals. This interval shall not be more than every 13 spaces. The width of landscaped islands perpendicular to adjacent spaces shall be no less than 6 feet.

4.

In addition to the requirements above for parking area landscaping, trees shall be planted in buffer areas and along frontage lines at a minimum frequency of one every 30 linear feet measured along the buffer or lot line. Trees shall be selected and placed in landscaped areas so that all parking areas can reasonably be expected to receive 30% Tree Canopy Coverage. The expected canopy radius of each selected tree shall be noted in the required site plan materials.

11.6.6.D.

Street Trees.

See Sec. 11.5.5 Street Trees.

11.6.6.E.

Irrigation Systems.

1.

When irrigation systems are provided, sustainable systems, such as low volume heads, drip irrigation, and other water efficiency methods are encouraged.

11.6.7.A.

General Standards.

1.

The objectives of the stormwater management standards are to reduce water quality impacts at receiving waters, enhance community character in support of compact development, and promote the public health, safety, and welfare. The stormwater management standards include the following goals:

(a)

Manage rainfall as close to where it falls as possible, approximating the natural pre-development hydrology (water quality and water quantity) by using natural, decentralized stormwater management practices that do not impede or negatively alter the historic flow of stormwater runoff.

(b)

Celebrate stormwater as an integral part of the built environment.

(c)

Establish watershed sensitive planning and design criteria at the neighborhood scale of development to support shared flood control solutions.

(d)

Encourage incorporation of Light Imprint Best Management Practices (BMPs) at the Block, street, and site scales of development, appropriate to land use context and site conditions.

2.

A Stormwater Management System shall be developed to manage stormwater in each Neighborhood as whole.

3.

Stormwater management shall be implemented within a Final Site Plan.

4.

Stormwater standards for individual Lots within the neighborhood can assist in meeting the standards of the neighborhood as a whole.

5.

All stormwater shall be managed in accordance with Divisions 9 and 10 of Article 4 of the Martin County Land Development Code.

11.6.7.B.

Light Imprint Storm Drainage Methods.

1.

Table 6-5 provides recommended stormwater management methods as outlined in the Light Imprint Handbook. These methods shall be utilized as the elements of the neighborhood stormwater strategy and the Final Site Plan detailed stormwater management plan. At least one of these methods shall be applied at the neighborhood, corridor, and Lot levels to implement the neighborhood stormwater strategy. Refer to the Light Imprint Handbook for comprehensive descriptions of each method and its application.

2.

The Light Imprint stormwater management methods appropriate for use within the Civic Transect Zone shall be determined by the Settlement Architect and the County on a site-by-site basis based on the use and character of each site.

11.6.7.C.

Design Criteria.

1.

Properly designed Pervious Paving shall be permitted and is encouraged to reduce stormwater runoff volume. Pervious Paving approaches may be technically infeasible where underlying soils are contaminated or other site constraints exist.

2.

Green roofs shall be permitted for all building types.

3.

Roof drains shall not outfall onto impervious pedestrian use areas and should instead be directed to underground storm drainage systems or a vegetated stormwater management system.

4.

Irrigation systems are encouraged to first make use of all available surface stormwater runoff or other retained or detained stormwater as a water supply.

5.

Bioretention systems, rain gardens, bioswales, tree filters, and other vegetated stormwater management systems are encouraged for treatment of stormwater runoff from streets, parking lots, plazas, and other impervious surfaces. These vegetated stormwater management systems can include impermeable liners with underdrains to provide water quality treatment where infiltration is not technically feasible due to site contamination concerns.

6.

Trees should be planted below the grade of the sidewalk and the street. Structural cells should be used for trees planted in tree wells, or in plazas or other paved areas, to ensure sufficient root space for healthy tree growth and to increase the stormwater management potential of the trees.

7.

Special Detention Areas such as parking lots, rooftops ("blue roofs"), parks, plazas, and fields are areas primarily designated for other uses but that may be used for temporary infiltration and/or peak rate mitigation during storm events if the requirements herein are satisfied. Special Detention Areas shall be designed sensitive to land use context and public use requirements and the following conditions:

(a)

Temporary storage areas must be located so that ponding will not significantly disrupt typical traffic (pedestrian/bicycle/vehicle) flow, and areas should be adequately sloped towards outlets to ensure complete drainage after storm events.

(b)

Special Detention Areas shall be clearly identified as such and their use shall be restricted during and after storms.

(c)

Emergency overflows shall be incorporated and designed to prevent excessive depths from occurring during extreme storm events or if the primary flow control structure/structures are clogged. In most cases, ponding depth shall not exceed 12 inches.

(d)

Rooftop storage must consider structural support, HVAC requirements, waterproofing, emergency overflows, and all other building design considerations.

(e)

Landscape or turf Special Detention Areas used for high-intensity public uses (community parks, athletic fields, greens, etc.) shall be located in areas of well-draining soils to guarantee public use is not compromised by excessively wet ground between rain events.
