Section 3. Political and Jurisdictional Boundaries

To eliminate potential jurisdictional disputes and to facilitate effective coordination and control of development, the Plan Commission shall be guided by the following policy:

Whenever access to the development is required across land in another local government, the Commission shall request assurance from that local governmental attorney that access is legally established, and from the local governmental engineer that the access road is adequately improved, or that a Performance Bond has been duly executed and is sufficient in amount to assure the construction of the access road.
Lot lines shall be laid out so as not to cross boundary lines between adjacent units of local government which has separate governing bodies for the purpose of regulation and control of land use and development, as well as for tax purposes.

Effective on: 9/24/2013

Section 4. Conditions of Development

Character of Land Suitable for Development
Land that the Plan Commission finds to be unsuitable for subdivision or development due to flooding, improper drainage, adverse earth formations or topography, utility easements, or other features that will reasonably be harmful to the safety, health, and general welfare of the present or future inhabitants of the development and/or its surrounding areas, shall not be subdivided or developed unless adequate methods are formulated by the developer and approved by the Planning Commission, upon recommendation of the Technical Advisory Committee, to solve the problems created by the unsuitable land conditions. Such land shall be set aside for uses as shall not involve any danger to public health, safety, and welfare.

Adequate Public Facilities
No primary plat shall be approved unless the Planning Commission determines that public facilities will be adequate to support and service the area of the proposed development. The applicant shall, at the request of the Planning Commission, submit sufficient information and data on the proposed development to demonstrate the expected impact on and use of public facilities by possible uses of said development. Public facilities and services to be examined for adequacy will include roads, sewerage, schools, and public safety agencies.

Reservation of Land for Public Use

Where a proposed park or other public use is shown on an Official Plan of the City, and said public use is located in whole or in part within a proposed development, sufficient area for the public use shall be dedicated to the public or reserved and offered for public purchase. If within five (5) years of plat recording the purchase is not agree on, the reservation shall be terminated. Space for public uses which is improved per public standards may count towards applicable Impact Fee Requirements.
Where it is deemed essential by the Plan Commission, upon consideration of the particular type of development proposed in the development, the needs for public services that the development will generate, and the policies of the Comprehensive Master Plan, the Commission may recommend and the Common Council may require the reservation of land for public use. Land required for dedication shall be of a location, size, and character consistent with the needs created by the development. Land for public uses which is improved per public standards may count towards applicable Impact Fee Requirements.

Extension Policies
All public improvements and required easements shall be extended through the parcel on which new development is proposed. Streets, water lines, wastewater systems, drainage facilities, electric lines, and telecommunications lines shall be constructed through new development to promote the logical extension of public infrastructure. The City may require the applicant of a development to extend off-site improvements to reach the development or oversize required public facilities to serve anticipated future development as a condition of plat approval. The cost of such extensions or over sizing shall be borne by the developer unless other provisions have been made to cover the cost via impact fee ordinances.

In long blocks the Plan Commission may require an easement through the block to accommodate utilities, drainage facilities, or pedestrian walkways where deemed essential to provide circulation or access to schools, playgrounds, shopping centers, transportation, or other community facilities. ORD. #10-03-13

Where blocks are developed along arterial streets and/or highways that shall contain alleys, those alleys shall run parallel to said arterial and not perpendicular or radial to it so as to create an intersection between the arterial and alley.

Effective on: 9/24/2013

Section 2. Lots

Lot Arrangement
The lot arrangements shall be such that there will be no foreseeable difficulties, for reasons of topography or other conditions, in securing building permits to build on all lots in compliance with the zoning ordinance and other regulations, in providing safe driveway access to buildings on such lots from an approved street, or in providing service to public sanitary sewer or approved sanitary disposal facilities.

Lot Dimensions

The areas of all lots shall not be less than the standards for the zoning district in which they are located.
{Corner lots shall be a minimum of fifty (50) percent larger than the minimum lot area indicated for the zoning district in which it is located.} ORD. #29-9-11
Depth and width of properties reserved or laid out for business, commercial, or industrial purposes shall be adequate to provide for the off-street parking and loading facilities required for the type of use and development contemplated, as established in the Zoning Ordinance.
Adequate depth shall be allotted to new blocks and lots to accommodate landscape buffers, where required.
Where individual septic tanks have been authorized, sufficient area shall be provided for a replacement sewage disposal system.

Lot Lines

The lot line common to the street right-of-way shall be the front line. All lots shall face the front line and a similar line across the street. Wherever feasible, lots shall be arranged so that the rear line does not abut the side line of an adjacent lot.

Lot Lines

1. In general, side lot lines shall be at right angles to street lines (or radial to curving street lines) unless a variation from this rule will give a better street or lot plan.
2. Building setback lines shall be established on all lots, and the minimum building set back line shall be appropriate for the location of the development and for type of development and use contemplated, provided, however, that they shall not be less than the standards established by the zoning ordinance of the City of Noblesville.

Lot Shape
Double frontage and reversed frontage lots shall be discouraged except where necessary to provide separation of residential development from arterial streets or to overcome specific disadvantages of topography and orientation. Flag lots shall be prohibited.
Access to Lots
Single- and Two-Family lots shall not derive access from an arterial or major collector. Multi-family and Nonresidential lots should not generally derive access exclusively from an arterial or major collector street. Where driveway access from an arterial or major collector street may be necessary for several adjoining lots, the Plan Commission may require that such lots be served by a common and combined driveway in order to limit possible traffic hazards on such street. Driveways shall be designed and arranged so as to avoid requiring vehicles to back into traffic on arterials and major collectors.
Water bodies and Watercourses
If a tract being subdivided contains a private water body, or portion thereof, lot lines shall be so drawn as to distribute the entire ownership of the water body among the fees of adjacent lots. The Planning Commission may approve an alternative plan whereby the ownership of and responsibility for safe maintenance of the water body is so placed that it will not become a local government responsibility. No more than twenty-five percent (25%) of the minimum area of a lot required under the Unified Development Ordinance may be satisfied by land that is under water. Where a watercourse separates the buildable area of a lot from the street by which it has access, provisions shall be made for installation of a culvert or other structure, of design approved by the City or County Engineer, as applicable.
Utility Easements
Easements across lots or centered on rear or side lot lines shall be provided for utilities where necessary and shall be at least fifteen (15) feet wide. Easements for streetlights shall be located as approved by the Board of Public Works and Safety.
Drainage
Lots shall be laid out to provide positive drainage away from all buildings. Individual lot drainage shall be coordinated with the general storm drainage pattern for the area.

Effective on: 9/24/2013

Section 1. Streets and Roads

Purpose
In order to provide for streets of suitable location, width, and improvement to accommodate expected traffic and afford satisfactory access to police, fire fighting, snow removal, sanitation, and road maintenance equipment, and to coordinate street development so as to compose a convenient system, avoid undue hardships to adjoining properties and assure compatibility with long range comprehensive plans, all streets shall be designed according to the standards set forth in these regulations.

In designing and approving subdivision streets, the following factors shall receive consideration:

Safety for all vehicular and pedestrian traffic;
Efficient ability of the roadway and related facilities to accommodate the modes of transportation it is anticipated to serve, including but not limited to pedestrians, passenger cars, buses, emergency services, and freight.
Livability or amenities as affected by traffic elements in the circulation system;
Economy of both construction and use of land.

Applicability
Design of major collector and arterial streets shall require special design and approval by the Engineer of the appropriate jurisdiction. The following design guidelines are specifically intended for streets within the subdivision, i.e., minor collectors and locals. Standards for each classification are found in this Part A.

General Provisions

Conformance with Thoroughfare Plan, Existing Development, and Natural Features.
1. All streets shall be properly integrated with the existing and proposed system of thoroughfares and dedicated rights-of-way, as established in the Comprehensive Master Plan.
2. All thoroughfares shall be properly related to special traffic generators such as industries, business districts, schools, churches, and shopping centers; to population densities; and to the pattern of existing and proposed land uses.
3. Minor or local streets shall be laid out to conform as much as possible to the topography, to discourage use by through traffic, to permit efficient drainage and utility systems, and to require the minimum number of streets necessary to provide convenient and safe access to property.
Public Streets {Required} ORD. #55-12-02
1. All arterial and collector streets, as shown on the {Official Noblesville Thoroughfare Plan Map, a part of the Comprehensive Master Plan} ORD. #55-12- 02, shall be dedicated to the public. {Local Streets may be Private Streets and shall meet the current adopted Noblesville Standards for local streets including right-of-way width, pavement width, pavement construction, etc., the Noblesville Standards and additional requirements of the Unified Development Ordinance. All private streets shall be inspected by the Engineering Department for compliance with the Unified Development Ordinance and Noblesville Standards.}. ORD. #89-10-06
Frontage on Improved Roads Required
No subdivision shall be approved unless the area to be subdivided shall have frontage on and access from an existing street or a street shown upon a plat approved by the Plan Commission and recorded in the County Recorder of Deeds’ office. Such street or highway must be suitably improved as required by this Division, or be secured by a performance bond required under the regulations of Article 5, Subdivisions.
Improvement of Noblesville Thoroughfares
Wherever the area to be subdivided is to utilize existing road frontage, the road shall be suitably improved as {required by the City Engineer and approved by the Plan Commission} ORD. #55-12-02. Whenever a proposed subdivision borders an existing {roadway, which is depicted on the adopted Noblesville Thoroughfare Plan, the developer shall be required to improve said roadway(s) in accordance with the Noblesville Standards.. The reconstruction or widening of such street as a condition of plat approval and additional dedication of right-of-way may also be required. Acceleration/Deceleration lanes and passing blisters shall be constructed for all new developments directly adjacent to a primary arterial, secondary arterial, major collector or INDOT right-of-way.} ORD. #55-12-02
Residential Subdivisions Abutting Arterials, Expressways, and Collectors
{Where a subdivision abuts or contains an arterial, expressway, and/or collector thoroughfare, the visual impact of both the rears of residential homes and the backyards of such lots adjacent to these thoroughfares shall be minimized. The minimization must be accomplished by one of the following methods:
1. Applicants may install a significant landscape and mounding treatment in order to visually screen the backyards and the first floor elevation of the exterior of homes on lots which abut such thoroughfares. Applicants shall provide elevation drawings of the typical section of the proposed mounding and landscaping treatment along with the common and scientific names and plant sizes at the time of planting and maturity of the plant species to be provided as a part of the subdivision application. The mound shall be a minimum height at the peak of four (4) feet and shall be planted as per the requirements of Article 12. An opaque fence or wall may be used in combination with the landscaping and mounding subject to the approval of the Noblesville Plan Commission.
2. Applicants may construct frontage roads approximately parallel to and on each side of such above mentioned thoroughfares, thus requiring the applicable perimeter home fronts to face the exterior of the development or the frontage road. Applicants shall be required to install street trees as per the Unified Development Ordinance requirements in Article 6 Site Design and Improvement Standards, Part M Street Trees on both sides of each frontage road. The trees on each side of the frontage road shall be staggered.
3. Applicants may provide other appropriate treatments, as deemed necessary and approved by the Noblesville Plan Commission, in order to minimize the visual impact of the rear façades of residential homes and backyards abutting the above mentioned thoroughfares.

1. The Noblesville Plan Commission may require such other treatment as is necessary for the adequate protection of the residential lots to separate through traffic from local traffic, and to lessen the visual impact of said development of public streets. Vehicular access from the residential lots to an arterial, collector, and/or expressway shall be prohibited. Any landscaping installed under ‘a’ or ‘c’ above shall be located within a dedicated and maintained easement and not within the public right-of-way.} ORD. #25-06-02

1. Half Streets
  Half streets shall be prohibited except where unusual circumstances make such a facility necessary to the reasonable development of a tract in conformance with these regulations and where satisfactory assurance for dedication of the remaining part of the street is provided. Whenever a tract to be subdivided borders on an existing half or partial street, the other part of the street shall be dedicated within such tract.
2. Continuation of Streets and Dead End-Streets
  1. Continuation of Streets (Stub Streets)
    Streets in new subdivisions should extend to the boundary line of the parcel to provide for the future extension of said streets into adjacent areas when the continuation is necessary for convenient movement of traffic, effective fire protection, for efficient provision of utilities, and where the continuation is in accordance with the Thoroughfare Plan. If the adjacent property is undeveloped and the street must temporarily be a dead-end street, the right-of-way shall be extended to the property line. A temporary T- or L-shaped turnabout shall be provided on all temporary dead-end streets, with the notation on the subdivision plat that land outside the normal street right-of-way shall revert to abutters whenever the street is continued. The Planning Commission may limit the length of temporary dead-end streets in accordance with the design standards of these regulations.
  2. Permanent Dead-End Streets (Cul-de-sacs)
    1. Where a road does not extend beyond the boundary of the subdivision and its continuation is not required by the Planning Commission for access to adjoining property, its terminus shall be in a cul-de-sac turn- around. Permanent dead-end streets (cul-de-sacs) shall not be longer than six hundred (600) feet.
      
      The minimum radii for cul-de-sacs shall be as follows:

Use Type	Right-of-way	{Center of Cul-de-sac} to back of curb ORD. 76-9-05
Residential	Fifty-{four (54)} feet	{Forty (40) feet} ORD. 55-12-02
Commercial Industrial	Sixty (60) feet Sixty (60) feet	Fifty (50) feet Fifty (50) feet

ORD #32-07-19

1. 1. 1. Wherever a minor collector street serves exclusively an industrial or commercial area, a cul-de-sac may be allowed and the length may be increased to 1,000 feet. This special provision shall be allowed only in areas which have a difficult access or are otherwise unsuitable for normal subdividing. However, a 48-foot pavement width shall be required in all cases under this special provision.
    2. All streets to be terminated on a temporary basis shall be constructed with a turnaround. Such turnaround shall be constructed beyond all lots intended for development. In a development which is not phased, the turnaround shall be developed in a way that will not preclude the future extension of the road.

1. Guidelines for Street Location and Arrangement in Commercial/Industrial Areas
  1. Alleys shall be provided in multiple dwelling or commercial subdivisions unless other provisions are made for service access and off-street loading and unloading. Dead-end alleys shall be prohibited.
  2. In business and industrial developments, the streets and other accessways shall be planned in connection with the grouping of buildings, location of rail facilities, and the provision of alleys, truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.
2. Maintenance of State Road 37 Right-of-Way
  For all new development abutting the right-of-way of SR 37, the developer shall request that the Indiana Department of Transportation (INDOT) remove any existing fence in said right-of-way. Thereafter, said right-of-way shall be maintained in good condition, along with other exterior spaces on the premises, by the abutting property owner.
3. {Right of way pavement widths refer to Noblesville Standards Sheet 2 – Right of Way} ORD. #55-12-02

Street Design Standards and Guidelines
1. Design Traffic Volumes.
  The design hourly volume (DHV) or average daily traffic (ADT) is the accepted basis for design. In rural areas, the Engineer of appropriate jurisdiction may amend the design standards as determined by traffic demand analysis. However, the traffic volume does not always determine the type of curves to be used in designing low volume residential local and minor collector streets. Traffic volumes are a major factor to be considered for streets serving commercial and industrial areas, and the Engineer of appropriate jurisdiction is required to give special attention to these areas.
2. Design Speed.
  Design speeds are a factor for urban residential local and minor collector design. In general, the same rule can be applied to rural low volume roads in subdivision design. The sight distances and curve radii are to be commensurate with average acceptable design speeds as indicated by the Indiana Design Manual.
3. Vertical Grades.
  Drainage design may become critical where grades exceed 4%. For this reason, grades lower than the suggested tabular values are encouraged. Commercial and industrial streets shall be held to a maximum grade of 4%. Residential streets shall in no case exceed the tabular values. In order to provide for proper drainage, the minimum grade should be held to 0.5%.
  
  The maximum grade on the approach leg of any intersection shall not exceed 5% in hilly terrain and 2% in level terrain.
4. {Superelevation.
  It should be considered in commercial and industrial areas and for collector streets where operating speeds may exceed 30 to 35 miles per hour. Where superelevation is used, street curves should be design for a maximum elevation rate of:
  1. Urban: 0.04 to 0.06 foot per foot
  2. Rural: 0.08 to 0.12 foot per foot

1. Superelevation shall only be used when the designer has demonstrated that the property horizontal curvature for the appropriate design speed and the regulatory speed limit cannot be attained. Where superelevation is not provided within residential areas, the proper signage shall be provided with the appropriate advisory speed supplemental plaque.} ORD. #95-11-06

1. Horizontal Alignment.
  Minimum centerline radii for horizontal curves shall be
  1. {Arterial/Major Collector: Per Indiana Design Manual
  2. Commercial/Industrial Collector/Residential Minor Collector: 225-FT
  3. Residential Local (serves less than 50 residences): 150-FT

1. The minimum tangent distance between reverse curves shall be
  1. Arterial/Major Collector: Per Indiana Design Manual
  2. Commercial/Industrial Collector: 200-FT
  3. Residential Minor Collector: 150-FT
  4. Residential Local (serves less than 50 residences): zero-FT} ORD. #56-11-07
  5. {Special Design exceptions for these requirements may be granted for roundabout design. Minimum design speeds and regulatory speed limits for the applicable roadway section shall apply. The use of spiral and compound curves is prohibited.} ORD. #95-11-06

1. Intersections.
  Intersections, including median openings, should be designed with adequate intersection sight distance. The recommended minimum {intersection sight distance shall be determined from the Indiana Design Manual related to Intersection Sight Distance based on the roadway design speed or posted speed limit.} In order to maintain these distances, the Engineer of appropriate jurisdiction or the Technical Advisory Committee may recommend regulations to restrict the height of embankment, location of buildings and screening fences and landscaping, and other provisions necessary for intersection sight control. ORD. #56-11-07
  
  The minimum intersection angle shall be 75 degrees.

Section 3. Installation, Responsibility, and Maintenance

Whenever sedimentation is caused by stripping vegetation, regrading, or other development, it shall be the responsibility of the applicant, person, corporation, or other entity causing such sedimentation to remove it from all adjoining surfaces, drainage systems, and watercourses and to repair any damage at his expense as quickly as possible.

Maintenance of all driveways, parking areas, drainage facilities, and watercourses within any development plan area is the responsibility of the applicant, or owner developer.

It is the responsibility of the applicant and any person, corporation, or other entity doing any act on or across a communal stream, watercourse, or swale or upon the flood plain or right-of-way thereof, to maintain as nearly as possible in its present state the stream, watercourse, swale, flood plain, or right-of-way during the duration of the activity and to return it to its original or equal condition after such activity is completed.

No applicant and person, corporation, or other entity shall block, impede the flow of, alter, construct any structure, or deposit any material or thing, or commit any act which will affect normal or flood flow in any communal stream or watercourse without having obtained prior approval from the Hamilton County Drainage Board or the Indiana Department of Natural Resources, Division of Water, whichever is applicable.

Where a Development Plan Area is traversed by a watercourse, the total development of the watercourse shall be considered. There shall be provided a drainage easement or right-of-way conforming substantially to the line of such watercourse, and of such width as will be adequate to preserve natural drainage.

Each applicant, person, corporation, or other entity which makes any surface changes shall be required to:

Collect on-site surface runoff and dispose of it to the point of discharge into an adequate outlet approved by the {City Engineer.} ORD. #55-12-02
Handle existing and potential off-site runoff through his development by designing to adequately handle storm runoff from a fully developed drainage area.
Pay his proportionate share of the total cost of off-site improvements to the common natural watercourse, based on a fully developed drainage area.
Provide and install at his expense all drainage and erosion control improvements (temporary and permanent) as required by the Erosion and Sediment control plan.

It is the responsibility of the applicant or owner to keep all major streams, not under the jurisdiction of another official agency, open and free flowing.

The applicant or owner will assume the responsibility for maintaining an open and free flowing condition in all minor streams, watercourses, and drainage systems, constructed or improved in accordance with City and County design criteria on his property, which are necessary for proper drainage in the discretion of the Director of Planning and Development if adequate right-of-way exists or can be acquired.

1. All arterial and collector streets, as shown on the {Official Noblesville Thoroughfare Plan Map, a part of the Comprehensive Master Plan} ORD. #55-12- 02, shall be dedicated to the public. {Local Streets may be Private Streets and shall meet the current adopted Noblesville Standards for local streets including right-of-way width, pavement width, pavement construction, etc., the Noblesville Standards and additional requirements of the Unified Development Ordinance. All private streets shall be inspected by the Engineering Department for compliance with the Unified Development Ordinance and Noblesville Standards.}. ORD. #89-10-06
Frontage on Improved Roads Required
No subdivision shall be approved unless the area to be subdivided shall have frontage on and access from an existing street or a street shown upon a plat approved by the Plan Commission and recorded in the County Recorder of Deeds’ office. Such street or highway must be suitably improved as required by this Division, or be secured by a performance bond required under the regulations of Article 5, Subdivisions.
Improvement of Noblesville Thoroughfares
Wherever the area to be subdivided is to utilize existing road frontage, the road shall be suitably improved as {required by the City Engineer and approved by the Plan Commission} ORD. #55-12-02. Whenever a proposed subdivision borders an existing {roadway, which is depicted on the adopted Noblesville Thoroughfare Plan, the developer shall be required to improve said roadway(s) in accordance with the Noblesville Standards.. The reconstruction or widening of such street as a condition of plat approval and additional dedication of right-of-way may also be required. Acceleration/Deceleration lanes and passing blisters shall be constructed for all new developments directly adjacent to a primary arterial, secondary arterial, major collector or INDOT right-of-way.} ORD. #55-12-02
Residential Subdivisions Abutting Arterials, Expressways, and Collectors
{Where a subdivision abuts or contains an arterial, expressway, and/or collector thoroughfare, the visual impact of both the rears of residential homes and the backyards of such lots adjacent to these thoroughfares shall be minimized. The minimization must be accomplished by one of the following methods:
1. Applicants may install a significant landscape and mounding treatment in order to visually screen the backyards and the first floor elevation of the exterior of homes on lots which abut such thoroughfares. Applicants shall provide elevation drawings of the typical section of the proposed mounding and landscaping treatment along with the common and scientific names and plant sizes at the time of planting and maturity of the plant species to be provided as a part of the subdivision application. The mound shall be a minimum height at the peak of four (4) feet and shall be planted as per the requirements of Article 12. An opaque fence or wall may be used in combination with the landscaping and mounding subject to the approval of the Noblesville Plan Commission.
2. Applicants may construct frontage roads approximately parallel to and on each side of such above mentioned thoroughfares, thus requiring the applicable perimeter home fronts to face the exterior of the development or the frontage road. Applicants shall be required to install street trees as per the Unified Development Ordinance requirements in Article 6 Site Design and Improvement Standards, Part M Street Trees on both sides of each frontage road. The trees on each side of the frontage road shall be staggered.
3. Applicants may provide other appropriate treatments, as deemed necessary and approved by the Noblesville Plan Commission, in order to minimize the visual impact of the rear façades of residential homes and backyards abutting the above mentioned thoroughfares.

1. The Noblesville Plan Commission may require such other treatment as is necessary for the adequate protection of the residential lots to separate through traffic from local traffic, and to lessen the visual impact of said development of public streets. Vehicular access from the residential lots to an arterial, collector, and/or expressway shall be prohibited. Any landscaping installed under ‘a’ or ‘c’ above shall be located within a dedicated and maintained easement and not within the public right-of-way.} ORD. #25-06-02

1. Half Streets
  Half streets shall be prohibited except where unusual circumstances make such a facility necessary to the reasonable development of a tract in conformance with these regulations and where satisfactory assurance for dedication of the remaining part of the street is provided. Whenever a tract to be subdivided borders on an existing half or partial street, the other part of the street shall be dedicated within such tract.
2. Continuation of Streets and Dead End-Streets
  1. Continuation of Streets (Stub Streets)
    Streets in new subdivisions should extend to the boundary line of the parcel to provide for the future extension of said streets into adjacent areas when the continuation is necessary for convenient movement of traffic, effective fire protection, for efficient provision of utilities, and where the continuation is in accordance with the Thoroughfare Plan. If the adjacent property is undeveloped and the street must temporarily be a dead-end street, the right-of-way shall be extended to the property line. A temporary T- or L-shaped turnabout shall be provided on all temporary dead-end streets, with the notation on the subdivision plat that land outside the normal street right-of-way shall revert to abutters whenever the street is continued. The Planning Commission may limit the length of temporary dead-end streets in accordance with the design standards of these regulations.
  2. Permanent Dead-End Streets (Cul-de-sacs)
    1. Where a road does not extend beyond the boundary of the subdivision and its continuation is not required by the Planning Commission for access to adjoining property, its terminus shall be in a cul-de-sac turn- around. Permanent dead-end streets (cul-de-sacs) shall not be longer than six hundred (600) feet.
      
      The minimum radii for cul-de-sacs shall be as follows:

Use Type	Right-of-way	{Center of Cul-de-sac} to back of curb ORD. 76-9-05
Residential	Fifty-{four (54)} feet	{Forty (40) feet} ORD. 55-12-02
Commercial Industrial	Sixty (60) feet Sixty (60) feet	Fifty (50) feet Fifty (50) feet

ORD #32-07-19

1. 1. 1. Wherever a minor collector street serves exclusively an industrial or commercial area, a cul-de-sac may be allowed and the length may be increased to 1,000 feet. This special provision shall be allowed only in areas which have a difficult access or are otherwise unsuitable for normal subdividing. However, a 48-foot pavement width shall be required in all cases under this special provision.
    2. All streets to be terminated on a temporary basis shall be constructed with a turnaround. Such turnaround shall be constructed beyond all lots intended for development. In a development which is not phased, the turnaround shall be developed in a way that will not preclude the future extension of the road.

1. Guidelines for Street Location and Arrangement in Commercial/Industrial Areas
  1. Alleys shall be provided in multiple dwelling or commercial subdivisions unless other provisions are made for service access and off-street loading and unloading. Dead-end alleys shall be prohibited.
  2. In business and industrial developments, the streets and other accessways shall be planned in connection with the grouping of buildings, location of rail facilities, and the provision of alleys, truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.
2. Maintenance of State Road 37 Right-of-Way
  For all new development abutting the right-of-way of SR 37, the developer shall request that the Indiana Department of Transportation (INDOT) remove any existing fence in said right-of-way. Thereafter, said right-of-way shall be maintained in good condition, along with other exterior spaces on the premises, by the abutting property owner.
3. {Right of way pavement widths refer to Noblesville Standards Sheet 2 – Right of Way} ORD. #55-12-02

Street Design Standards and Guidelines
1. Design Traffic Volumes.
  The design hourly volume (DHV) or average daily traffic (ADT) is the accepted basis for design. In rural areas, the Engineer of appropriate jurisdiction may amend the design standards as determined by traffic demand analysis. However, the traffic volume does not always determine the type of curves to be used in designing low volume residential local and minor collector streets. Traffic volumes are a major factor to be considered for streets serving commercial and industrial areas, and the Engineer of appropriate jurisdiction is required to give special attention to these areas.
2. Design Speed.
  Design speeds are a factor for urban residential local and minor collector design. In general, the same rule can be applied to rural low volume roads in subdivision design. The sight distances and curve radii are to be commensurate with average acceptable design speeds as indicated by the Indiana Design Manual.
3. Vertical Grades.
  Drainage design may become critical where grades exceed 4%. For this reason, grades lower than the suggested tabular values are encouraged. Commercial and industrial streets shall be held to a maximum grade of 4%. Residential streets shall in no case exceed the tabular values. In order to provide for proper drainage, the minimum grade should be held to 0.5%.
  
  The maximum grade on the approach leg of any intersection shall not exceed 5% in hilly terrain and 2% in level terrain.
4. {Superelevation.
  It should be considered in commercial and industrial areas and for collector streets where operating speeds may exceed 30 to 35 miles per hour. Where superelevation is used, street curves should be design for a maximum elevation rate of:
  1. Urban: 0.04 to 0.06 foot per foot
  2. Rural: 0.08 to 0.12 foot per foot

1. Superelevation shall only be used when the designer has demonstrated that the property horizontal curvature for the appropriate design speed and the regulatory speed limit cannot be attained. Where superelevation is not provided within residential areas, the proper signage shall be provided with the appropriate advisory speed supplemental plaque.} ORD. #95-11-06

1. Horizontal Alignment.
  Minimum centerline radii for horizontal curves shall be
  1. {Arterial/Major Collector: Per Indiana Design Manual

Blocks on local streets in residential areas shall not be more that one thousand (1,000) feet nor less than four hundred (400) feet in length.
Wherever practical, blocks along major arterials and collector streets should be a minimum of one thousand (1,000) feet in length.
Blocks designed for industrial uses shall be of such length and width as may be determined suitable by the Planning Commission for the prospective use.

Effective on: 9/24/2013

Section 2. Lots

Lot Dimensions

The areas of all lots shall not be less than the standards for the zoning district in which they are located.
{Corner lots shall be a minimum of fifty (50) percent larger than the minimum lot area indicated for the zoning district in which it is located.} ORD. #29-9-11
Depth and width of properties reserved or laid out for business, commercial, or industrial purposes shall be adequate to provide for the off-street parking and loading facilities required for the type of use and development contemplated, as established in the Zoning Ordinance.
Adequate depth shall be allotted to new blocks and lots to accommodate landscape buffers, where required.
Where individual septic tanks have been authorized, sufficient area shall be provided for a replacement sewage disposal system.

Lot Lines

The lot line common to the street right-of-way shall be the front line. All lots shall face the front line and a similar line across the street. Wherever feasible, lots shall be arranged so that the rear line does not abut the side line of an adjacent lot.

Lot Lines

1. In general, side lot lines shall be at right angles to street lines (or radial to curving street lines) unless a variation from this rule will give a better street or lot plan.
2. Building setback lines shall be established on all lots, and the minimum building set back line shall be appropriate for the location of the development and for type of development and use contemplated, provided, however, that they shall not be less than the standards established by the zoning ordinance of the City of Noblesville.

Lot Shape
Double frontage and reversed frontage lots shall be discouraged except where necessary to provide separation of residential development from arterial streets or to overcome specific disadvantages of topography and orientation. Flag lots shall be prohibited.
Access to Lots
Single- and Two-Family lots shall not derive access from an arterial or major collector. Multi-family and Nonresidential lots should not generally derive access exclusively from an arterial or major collector street. Where driveway access from an arterial or major collector street may be necessary for several adjoining lots, the Plan Commission may require that such lots be served by a common and combined driveway in order to limit possible traffic hazards on such street. Driveways shall be designed and arranged so as to avoid requiring vehicles to back into traffic on arterials and major collectors.
Water bodies and Watercourses
If a tract being subdivided contains a private water body, or portion thereof, lot lines shall be so drawn as to distribute the entire ownership of the water body among the fees of adjacent lots. The Planning Commission may approve an alternative plan whereby the ownership of and responsibility for safe maintenance of the water body is so placed that it will not become a local government responsibility. No more than twenty-five percent (25%) of the minimum area of a lot required under the Unified Development Ordinance may be satisfied by land that is under water. Where a watercourse separates the buildable area of a lot from the street by which it has access, provisions shall be made for installation of a culvert or other structure, of design approved by the City or County Engineer, as applicable.
Utility Easements
Easements across lots or centered on rear or side lot lines shall be provided for utilities where necessary and shall be at least fifteen (15) feet wide. Easements for streetlights shall be located as approved by the Board of Public Works and Safety.
Drainage
Lots shall be laid out to provide positive drainage away from all buildings. Individual lot drainage shall be coordinated with the general storm drainage pattern for the area.

Effective on: 9/24/2013

General Provisions

Conformance with Thoroughfare Plan, Existing Development, and Natural Features.
1. All streets shall be properly integrated with the existing and proposed system of thoroughfares and dedicated rights-of-way, as established in the Comprehensive Master Plan.
2. All thoroughfares shall be properly related to special traffic generators such as industries, business districts, schools, churches, and shopping centers; to population densities; and to the pattern of existing and proposed land uses.
3. Minor or local streets shall be laid out to conform as much as possible to the topography, to discourage use by through traffic, to permit efficient drainage and utility systems, and to require the minimum number of streets necessary to provide convenient and safe access to property.
Public Streets {Required} ORD. #55-12-02
1. All arterial and collector streets, as shown on the {Official Noblesville Thoroughfare Plan Map, a part of the Comprehensive Master Plan} ORD. #55-12- 02, shall be dedicated to the public. {Local Streets may be Private Streets and shall meet the current adopted Noblesville Standards for local streets including right-of-way width, pavement width, pavement construction, etc., the Noblesville Standards and additional requirements of the Unified Development Ordinance. All private streets shall be inspected by the Engineering Department for compliance with the Unified Development Ordinance and Noblesville Standards.}. ORD. #89-10-06
Frontage on Improved Roads Required
No subdivision shall be approved unless the area to be subdivided shall have frontage on and access from an existing street or a street shown upon a plat approved by the Plan Commission and recorded in the County Recorder of Deeds’ office. Such street or highway must be suitably improved as required by this Division, or be secured by a performance bond required under the regulations of Article 5, Subdivisions.
Improvement of Noblesville Thoroughfares
Wherever the area to be subdivided is to utilize existing road frontage, the road shall be suitably improved as {required by the City Engineer and approved by the Plan Commission} ORD. #55-12-02. Whenever a proposed subdivision borders an existing {roadway, which is depicted on the adopted Noblesville Thoroughfare Plan, the developer shall be required to improve said roadway(s) in accordance with the Noblesville Standards.. The reconstruction or widening of such street as a condition of plat approval and additional dedication of right-of-way may also be required. Acceleration/Deceleration lanes and passing blisters shall be constructed for all new developments directly adjacent to a primary arterial, secondary arterial, major collector or INDOT right-of-way.} ORD. #55-12-02
Residential Subdivisions Abutting Arterials, Expressways, and Collectors
{Where a subdivision abuts or contains an arterial, expressway, and/or collector thoroughfare, the visual impact of both the rears of residential homes and the backyards of such lots adjacent to these thoroughfares shall be minimized. The minimization must be accomplished by one of the following methods:
1. Applicants may install a significant landscape and mounding treatment in order to visually screen the backyards and the first floor elevation of the exterior of homes on lots which abut such thoroughfares. Applicants shall provide elevation drawings of the typical section of the proposed mounding and landscaping treatment along with the common and scientific names and plant sizes at the time of planting and maturity of the plant species to be provided as a part of the subdivision application. The mound shall be a minimum height at the peak of four (4) feet and shall be planted as per the requirements of Article 12. An opaque fence or wall may be used in combination with the landscaping and mounding subject to the approval of the Noblesville Plan Commission.
2. Applicants may construct frontage roads approximately parallel to and on each side of such above mentioned thoroughfares, thus requiring the applicable perimeter home fronts to face the exterior of the development or the frontage road. Applicants shall be required to install street trees as per the Unified Development Ordinance requirements in Article 6 Site Design and Improvement Standards, Part M Street Trees on both sides of each frontage road. The trees on each side of the frontage road shall be staggered.
3. Applicants may provide other appropriate treatments, as deemed necessary and approved by the Noblesville Plan Commission, in order to minimize the visual impact of the rear façades of residential homes and backyards abutting the above mentioned thoroughfares.

1. The Noblesville Plan Commission may require such other treatment as is necessary for the adequate protection of the residential lots to separate through traffic from local traffic, and to lessen the visual impact of said development of public streets. Vehicular access from the residential lots to an arterial, collector, and/or expressway shall be prohibited. Any landscaping installed under ‘a’ or ‘c’ above shall be located within a dedicated and maintained easement and not within the public right-of-way.} ORD. #25-06-02

1. Half Streets
  Half streets shall be prohibited except where unusual circumstances make such a facility necessary to the reasonable development of a tract in conformance with these regulations and where satisfactory assurance for dedication of the remaining part of the street is provided. Whenever a tract to be subdivided borders on an existing half or partial street, the other part of the street shall be dedicated within such tract.
2. Continuation of Streets and Dead End-Streets
  1. Continuation of Streets (Stub Streets)
    Streets in new subdivisions should extend to the boundary line of the parcel to provide for the future extension of said streets into adjacent areas when the continuation is necessary for convenient movement of traffic, effective fire protection, for efficient provision of utilities, and where the continuation is in accordance with the Thoroughfare Plan. If the adjacent property is undeveloped and the street must temporarily be a dead-end street, the right-of-way shall be extended to the property line. A temporary T- or L-shaped turnabout shall be provided on all temporary dead-end streets, with the notation on the subdivision plat that land outside the normal street right-of-way shall revert to abutters whenever the street is continued. The Planning Commission may limit the length of temporary dead-end streets in accordance with the design standards of these regulations.
  2. Permanent Dead-End Streets (Cul-de-sacs)
    1. Where a road does not extend beyond the boundary of the subdivision and its continuation is not required by the Planning Commission for access to adjoining property, its terminus shall be in a cul-de-sac turn- around. Permanent dead-end streets (cul-de-sacs) shall not be longer than six hundred (600) feet.
      
      The minimum radii for cul-de-sacs shall be as follows:

Use Type	Right-of-way	{Center of Cul-de-sac} to back of curb ORD. 76-9-05
Residential	Fifty-{four (54)} feet	{Forty (40) feet} ORD. 55-12-02
Commercial Industrial	Sixty (60) feet Sixty (60) feet	Fifty (50) feet Fifty (50) feet

ORD #32-07-19

1. 1. 1. Wherever a minor collector street serves exclusively an industrial or commercial area, a cul-de-sac may be allowed and the length may be increased to 1,000 feet. This special provision shall be allowed only in areas which have a difficult access or are otherwise unsuitable for normal subdividing. However, a 48-foot pavement width shall be required in all cases under this special provision.
    2. All streets to be terminated on a temporary basis shall be constructed with a turnaround. Such turnaround shall be constructed beyond all lots intended for development. In a development which is not phased, the turnaround shall be developed in a way that will not preclude the future extension of the road.

1. Guidelines for Street Location and Arrangement in Commercial/Industrial Areas
  1. Alleys shall be provided in multiple dwelling or commercial subdivisions unless other provisions are made for service access and off-street loading and unloading. Dead-end alleys shall be prohibited.
  2. In business and industrial developments, the streets and other accessways shall be planned in connection with the grouping of buildings, location of rail facilities, and the provision of alleys, truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of movement between the various types of traffic, including pedestrian.
2. Maintenance of State Road 37 Right-of-Way
  For all new development abutting the right-of-way of SR 37, the developer shall request that the Indiana Department of Transportation (INDOT) remove any existing fence in said right-of-way. Thereafter, said right-of-way shall be maintained in good condition, along with other exterior spaces on the premises, by the abutting property owner.
3. {Right of way pavement widths refer to Noblesville Standards Sheet 2 – Right of Way} ORD. #55-12-02

Street Design Standards and Guidelines
1. Design Traffic Volumes.
  The design hourly volume (DHV) or average daily traffic (ADT) is the accepted basis for design. In rural areas, the Engineer of appropriate jurisdiction may amend the design standards as determined by traffic demand analysis. However, the traffic volume does not always determine the type of curves to be used in designing low volume residential local and minor collector streets. Traffic volumes are a major factor to be considered for streets serving commercial and industrial areas, and the Engineer of appropriate jurisdiction is required to give special attention to these areas.
2. Design Speed.
  Design speeds are a factor for urban residential local and minor collector design. In general, the same rule can be applied to rural low volume roads in subdivision design. The sight distances and curve radii are to be commensurate with average acceptable design speeds as indicated by the Indiana Design Manual.
3. Vertical Grades.
  Drainage design may become critical where grades exceed 4%. For this reason, grades lower than the suggested tabular values are encouraged. Commercial and industrial streets shall be held to a maximum grade of 4%. Residential streets shall in no case exceed the tabular values. In order to provide for proper drainage, the minimum grade should be held to 0.5%.
  
  The maximum grade on the approach leg of any intersection shall not exceed 5% in hilly terrain and 2% in level terrain.
4. {Superelevation.
  It should be considered in commercial and industrial areas and for collector streets where operating speeds may exceed 30 to 35 miles per hour. Where superelevation is used, street curves should be design for a maximum elevation rate of:
  1. Urban: 0.04 to 0.06 foot per foot
  2. Rural: 0.08 to 0.12 foot per foot

1. Superelevation shall only be used when the designer has demonstrated that the property horizontal curvature for the appropriate design speed and the regulatory speed limit cannot be attained. Where superelevation is not provided within residential areas, the proper signage shall be provided with the appropriate advisory speed supplemental plaque.} ORD. #95-11-06

1. Horizontal Alignment.
  Minimum centerline radii for horizontal curves shall be
  1. {Arterial/Major Collector: Per Indiana Design Manual
  2. Commercial/Industrial Collector/Residential Minor Collector: 225-FT
  3. Residential Local (serves less than 50 residences): 150-FT

1. The minimum tangent distance between reverse curves shall be
  1. Arterial/Major Collector: Per Indiana Design Manual
  2. Commercial/Industrial Collector: 200-FT
  3. Residential Minor Collector: 150-FT
  4. Residential Local (serves less than 50 residences): zero-FT} ORD. #56-11-07
  5. {Special Design exceptions for these requirements may be granted for roundabout design. Minimum design speeds and regulatory speed limits for the applicable roadway section shall apply. The use of spiral and compound curves is prohibited.} ORD. #95-11-06

1. Intersections.
  Intersections, including median openings, should be designed with adequate intersection sight distance. The recommended minimum {intersection sight distance shall be determined from the Indiana Design Manual related to Intersection Sight Distance based on the roadway design speed or posted speed limit.} In order to maintain these distances, the Engineer of appropriate jurisdiction or the Technical Advisory Committee may recommend regulations to restrict the height of embankment, location of buildings and screening fences and landscaping, and other provisions necessary for intersection sight control. ORD. #56-11-07
  
  The minimum intersection angle shall be 75 degrees.
  
  Closely spaced offset intersections are undesirable. The minimum intersection centerline offset (jog) for the following intersections shall be
  1. {Residential - Local/Commercial/Industrial Collectors with Residential – Local/Commercial/ Industrial Collectors: 150-FT
  2. Arterial/Major Collector with any drive, public or private: Intersection Sight Distance (ISD) shall be determined using the design speed for the affected roadways. Intersection Sight Distance shall be analyzed and meet the requirements for Intersection Sight Distance in Chapter 46, Intersections at Grade of the Indiana Design Manual for all driveways and intersections. Vision Corner Clearance for all intersections and drives shall also meet the requirements of Article 9, Part A. Section 8 of the Unified Development Ordinance. The location for all sight distance evaluations shall be from the estimated location of the driver while the design vehicle is stopped at the required yield point. If the location has no defined yield point, the established yield point for the vehicle shall be the right-of-way line. Driveways, entrances, or streets not meeting this section shall have movements restricted or the entrance relocated.} ORD. #56-11- 07

1. To accommodate transitional tapers, turning lanes, and other potential roadway design requirements where needed, the Engineer of appropriate jurisdiction may recommend longer offsets.
  
  {Throating or center median curb may be required for all drives, public or private, which connect to a Major Collector or Arterial to prevent queuing within the right-of- way. If the distance from the edge of traveled way to the nearest edge of drive is equal to or less than the values below, the entry drive of street shall be throated or provided with center curb.
  1. Arterials: 100-FT
  2. Major Collectors: 75-FT
  3. Minor Collector; Commercial/Industrial, Local: zero feet.} ORD. #56-11-07
2. The minimum curb return radius at local streets shall be 15 feet and at residential collector streets 20 feet. The desirable radius is 25 to 30 feet, respectively. On commercial and industrial streets, the radius shall be 30 feet, except where traffic conditions may warrant a smaller radius.

No intersection shall be constructed with more than four approach legs, and the development of three legged “T” intersections is encouraged due to the increased safety of such intersections.

Section 1. General Requirements

{Erosion Control Plans shall be reviewed concurrently with the development plan and become a part thereof.} ORD #32-07-19

Effective on: 7/23/2019

Section 2. Review of Erosion Control Plans

Stripping of vegetation, regrading, or other development shall be done in such a way that will minimize erosion.
Development plans shall preserve salient natural features, keep cut-fill operations to a minimum, and ensure conformity with topography so as to create the least erosion potential and adequately handle the volume and velocity of surface water runoff.
Whenever feasible, natural vegetation shall be retained, protected, and supplemented.
The disturbed area and the duration of exposure shall be kept to a practical minimum.
Disturbed soils shall be stabilized as quickly as practical.
Temporary vegetation and mulching shall be used to protect exposed critical areas during development.
The permanent final vegetation and structural erosion control and drainage measures shall be installed as soon as practical in the development.
Provisions shall be made to effectively accommodate the increased runoff caused by changed soil and surface conditions during and after development. Where necessary, the rate of surface water runoff will be structurally retarded.
Sediment in the runoff water shall be trapped until the disturbed area is stabilized by the use of debris basins, sediment basins, silt traps, or similar measures.
{Development plan design shall strive for cut and fill site balancing with a minimum volume of residual dirt stockpiled.} ORD #25-04-15
{Ordinance No. 24-4-05 “An Ordinance Regulating Storm Water Run-off Associated with Construction and Post Construction Activities in the City of Noblesville” and all amendments thereto. (See Appendix H)} ORD. #32-10-11

Design Standards

Measures used to control erosion and reduce sedimentation and to provide drainage shall, as a minimum, meet the standards and specifications of the Hamilton County Soil & Water Conservation District. The {Technical Advisory Committee} ORD. #55- 12-02 shall ensure compliance with the appropriate specifications, copies of which are available from the Hamilton County Soil & Water Conservation District or the Department of Planning and Development. The applicable guides are: “URBAN DEVELOPMENT PLANNING GUIDE”, and “URBAN SOIL AND WATER CONSERVATION GUIDELINES, SPECIFICATION NO.1”.
In order to provide more suitable sites for building and other uses, improve surface drainage, and control erosion, the following requirements shall be met:
1. The location, grading, and placement of subgrade (base) material of all driveway and parking areas shall be accomplished as the first work done in a development plan.
2. All lots, tracts, or parcels shall be graded to provide proper drainage away from buildings and dispose of it without ponding; and all land within a development shall be graded to drain and dispose of surface water without ponding.
3. All drainage provisions shall be of such design to adequately handle the surface runoff and carry it to the nearest suitable outlet such as a curbed street, storm drain, or natural watercourse. Where drainage swales are used to divert surface waters away from buildings, they shall be sodded or planted as required and shall be of such slope, shape, and size as to conform with the requirements of the City of Noblesville or Hamilton County, as the case may be.
4. Concentration of surface water runoff shall be permitted only in swales or watercourses.
5. Excavation and fills:
  1. {Temporary dirt stockpiles shall be maintained with a slope no greater than 3:1 and a height of no greater than twenty (20) feet above grade of the adjacent roadway.
  2. Permanent dirt stockpiles shall be maintained with a slope of no greater than 4:1 and a height of no greater than fifteen (15) feet above the grade of the adjacent roadway.} ORD #25-04-15
  3. Provisions shall be made to prevent surface water from damaging the cut face of excavations or the sloping surfaces of fills by installation of temporary or permanent drainage across or above these areas.
  4. Cuts and fills shall not endanger adjoining property.
  5. Fill shall be placed and compacted so as to minimize sliding or erosion of the soil.
  6. Fills shall not encroach on natural watercourses or constructed channels.
  7. Fills placed adjacent to natural watercourses of constructed channels shall have suitable protection against erosion during periods of flooding.
  8. Grading will not be done in such a way so as to divert water onto the property of another land owner.
  9. During grading operations, necessary measures for dust control will be exercised.
  10. Grading equipment will not be allowed to cross live streams. Provision will be made for the installation of temporary or permanent culverts or bridges.
  11. {Cut and Fill operations in the floodplain; refer to Article 8 – Zoning Districts, Part G. Flood Hazard District.} ORD #25-04-15

Effective on: 7/23/2019

Section 3. Installation, Responsibility, and Maintenance

Maintenance of all driveways, parking areas, drainage facilities, and watercourses within any development plan area is the responsibility of the applicant, or owner developer.

Each applicant, person, corporation, or other entity which makes any surface changes shall be required to:

Collect on-site surface runoff and dispose of it to the point of discharge into an adequate outlet approved by the {City Engineer.} ORD. #55-12-02
Handle existing and potential off-site runoff through his development by designing to adequately handle storm runoff from a fully developed drainage area.
Pay his proportionate share of the total cost of off-site improvements to the common natural watercourse, based on a fully developed drainage area.
Provide and install at his expense all drainage and erosion control improvements (temporary and permanent) as required by the Erosion and Sediment control plan.

It is the responsibility of the applicant or owner to keep all major streams, not under the jurisdiction of another official agency, open and free flowing.

Effective on: 9/24/2013

Section 4. Enforcement

In the event the applicant or developer proceeds to clear and grade prior to the approval of the Development Plan, the Board of Zoning Appeals may revoke the approval of all plans.

Section 2. Standards

Each non-residential area or parcel shall be shown and marked on the plat as to its intended use.
Proposed non-residential parcels shall be suitable in area and dimensions to the types of development anticipated.
The engineer of appropriate jurisdiction shall approve in writing prior to secondary plat approval a provision that the proposed non-residential development will not conflict with traffic circulation patterns, and the requirements for driveway location and design can reasonably be implemented at no cost to the City/County.
Every effort shall be made to protect adjacent residential areas from potential nuisance from a proposed nonresidential development, including the provision of extra depth in parcels backing upon an existing or potential residential development, and provisions for a permanently landscaped buffer strip when necessary.
Truck Routes shall be established so as to prevent industrial traffic from encroaching into adjacent residential areas.
To the greatest degree possible, nonresidential developments shall be located on arterials or major collectors.
