I. Location Map: A small-scale two thousand feet to one inch (2,000' = 1") drawing of the region in which the subdivision is situated, showing the location of the subdivision, and indicating its relationship to traffic arteries, community facilities, railroads and other nonresidential land uses or adverse influences within a radius of two (2) miles. Current boundary lines of all municipalities within the area of this drawing shall be shown.
J. Proposed Public Improvements: Proposed public improvements for future construction on or near the tract, according to the information received from the Plat Officer at the sketch plan conference.
K. Subsurface Conditions: Subsurface conditions describing depth of ground water unless test pits are dry at a depth of eight feet (8'); location and results of any tests made to ascertain subsurface soil and rock conditions.
L. On-Site (Septic) Sewage Disposal Systems: A report from the Lake County Health Department indicating approval of the subdivision for septic systems shall be submitted for any subdivision with lots to be served by individual on-site (septic) sewage disposal.

N. Proposed Easements: Proposed easements showing location, width and purpose.
O. Lot Lines, Building Setback Lines: Lot line approximate dimensions and building setback lines.
P. Reservations, Dedications: Sites to be reserved or dedicated for any public or semi-public use.
Q. Conservancy Areas: The conservancy areas shall be depicted on the face of the plat and the following language shall be included verbatim on the face of the plat:

2. The flood plain shall not be filled nor shall the grade be altered in any respect.
3. No materials shall be utilized or stored which shall have the potential for polluting either surface or ground water.
4. There shall be no floodway alteration.
5. There shall be no disturbing of natural vegetation.
R. Water Facilities: The location of all lakes, ponds, detention sites, retention sites and dams shall be depicted, and accurately located on the final plat.

T. Proposed Contours: Proposed contours of the finished subdivision.
U. Proposed Agreements: Proposed agreements, bylaws, provisions or covenants which govern the use, maintenance, insurance and continued protection of the proposed development and its common open areas and other facilities.
V. Supplementary Plans and Drawings: When unusual site conditions exist, the Plat Officer may require such additional plans, specifications and drawings as he finds necessary for an adequate review of the plat. The Plat Officer shall request this additional material from the subdivider by letter, stating therein the information requested and the particular or unusual site conditions which make this information necessary.
All of the requirements of plat preparation shall apply equally to the site being subdivided and to all land within two hundred feet (200') of its boundaries, waiving accuracy requirements as to scale of features but not as to boundary lines. (Ord. 90-03, 7-25-90)
