The subdivider shall submit the number of prints specified by the code administrator. The plat shall, at a minimum, include the following information:

General

Proposed name of subdivision

Location by township, range and section, and legal description

Name and address of subdivider

Name and address of surveyor

Existing zoning of proposed subdivision and adjacent tracts

Subdivision

The layout to scale of all proposed and existing lots, numbered in sequential order, with appropriate dimensions and the minimum area in square feet for each lot and proposed front, side and rear yard setback lines

Delineation of the phases, if any, of the development, indicating the lots and improvements to be included in each phase

Parcels of land intended to be dedicated or temporarily reserved for public use or set aside for use of property owners in the subdivision

Infrastructure

All existing permanent fixtures that may influence the design of the subdivision, such as: existing buildings, power transmission towers, sewers, water mains, storm sewers, county ditches or drains, dry wells, utility lines and fire hydrants.

The direction of the flow shall be noted for sanitary sewers and storm sewers

Locations, dimensions and names of all existing or prior platted streets or other public ways, railroad and utility rights-of-way, parks and other public open spaces, permanent buildings and structures within and adjoining the proposed plat

The proposed location and size of all storm sewers, drainage structures and stormwater management facilities

Typical street cross-sections for each proposed street type in the subdivision

Natural features

Topographic contours at vertical intervals of two feet, if the general slope of the site and adjacent roadways is less than ten percent. Topographic contours at vertical intervals of five feet will be permitted where the general slope is greater than or equal to ten percent

All existing natural fixtures that may influence the design of the subdivision, such as: water courses, regulated drains, tree groves, wetlands, floodplains, outstanding natural topographic features, scenic or historic areas

Certifications

All applicable certificates and notations as required in Appendix I.

 

(b)

(2)

A description of the protective or private restrictions or covenants to be incorporated in the plat of the subdivision that will run with the land;

(3)

A landscape plan, specifying the type, size and location of all plants and other landscape materials;

(4)

Specifications for any required improvements to existing roads;

(5)

Erosion control plan;

(6)

Sewage disposal plan;

(7)

Water supply plan;

(8)

Stormwater management plan;

(9)

Street lighting plan;

(10)

A plan for the provision, ownership, maintenance and financing of improvements or systems that are to be owned and/or maintained by the home owners association;

(11)

An identification of the nearest public water and sewer mains and an analysis of the estimated cost and feasibility of connecting to public water and sewer;

(12)

Sewage system approval:

a.

If the development is to contain individual subsurface disposal systems, the subdivider must show that the design criteria in Article 06 are met, and that each lot has a certificate from the county health department indicating that a system can be installed on the property and detailing any required conditions. These conditions shall be recorded as part of the approved subdivision.

b.

If the development is to be served by a public or community sewer system, the subdivider must provide evidence that the system has the capacity and capability to serve the development and guarantee a sufficient number of hook-ups to serve all lots in the subdivision.

c.

If the development is to be served by a private system, the subdivider must provide evidence that the system design has been approved by the Indiana Department of Environmental Management, that there are guarantees to ensure continued operation and maintenance of the system and that the system has or will have sufficient capacity and number of hook-ups to serve all lots in the subdivision.

(13)

Land suitability summary, containing the following information:

a.

For lots that will be served by individual subsurface sewerage disposal systems, the number of acres or square feet of contiguous land with limitations for septic systems in accordance with the Indiana State Board of Health 410 IAC Rule 8.1.

b.

The number of acres or square feet of land located in a floodway, floodway fringe, flood zone A district (with each type of flood hazard area calculated separately), and the amount of land that is not located in a flood hazard area.

(14)

A stormwater management plan for the drainage of the parcel to be subdivided shall be submitted showing:

a.

The delineation of the drainage area in which the subdivision is located and the location of drainage courses and surface water flow within the drainage area.

b.

The existing on-site drainage facilities and a plan for storm water drainage for the parcel showing a method of dispersion or retention in accordance with section 06.07.

c.

Plans must show all off-site upstream watershed contribution. Drainage facilities shall be provided to allow drainage of water runoff from all of the upstream drainage area and from all areas within the proposed subdivision to a place adequate to receive such runoff. All upland stormwater must be accounted for in terms of rates and volume and plans must demonstrate that downstream water conveyances within the watershed are hydraulically adequate to accept the designed stormwater release rates to the ultimate outlet.
