Streets, curbs, and traffic-control devices have the following minimum standards:
(A) Alignment of the centerlines of intersecting streets shall be as close to right angles as possible. The simultaneous intersection of streets resulting in traffic from more than four directions is prohibited. The minimum radius of horizontal curvature shall be 500 feet for arterial, commercial, and industrial streets, and 250 feet for collector and residential streets.
(B) Rights-of-way for residential and collector streets shall be not less than 60 feet in width. For commercial, arterial, and industrial streets, the minimum right-of-way shall be not less than 80 feet in width, but where they form continuations of existing streets or thoroughfares, their widths shall be the same as those with which they form continuations.
(C) No two streets shall intersect at an angle of less than 70 degrees nor more than 110 degrees except with the special written consent of the Commission.
(D) All streets shall connect to existing streets with a minimum of jogs and angles, and no street or thoroughfare shall have an overall right-of-way of less than 60 feet, of which there shall not be less than 30 feet between the back of curbs. Enforcement of parking restrictions shall commence upon construction of any structure within the development. The Plan Commission may require roads of 36 feet wide between the back of curbs on primary thoroughfares through a subdivision or development when deemed appropriate by the Plan Commission upon advisory review recommendation of the Town Engineer.
(E) Acceleration or deceleration lanes and passing blisters, as approved by the Town Engineer, shall be required of the developer at all intersections with arterial streets or as otherwise determined by the Town Engineer.
(F) Street curb intersections shall be rounded by a curve, the minimum radius of which shall be 15 feet, except where existing improvements interfere, and the Zoning Administrator concurs.
(G) Dead-end, also called cul-de-sac, streets and alleys are specifically prohibited except in cases where topography or existing development of the land leaves no other alternative, in which event dead-end streets shall not be more than 300 feet in length. They shall terminate in a circular right-of-way with a minimum radius 75 feet and a paved turning circle with a minimum radius of 60 feet. No islands shall be allowed within cul-de-sacs.
(H) Streets which require ingress and egress over lands of adjoining property owners shall require proper written easements or other written agreements showing consents by those adjoining owners, which are properly recorded in the Lake County Recorder's Office. However, the layout of proposed streets should, to the greatest extent possible, provide for connectivity with adjoining subdivisions or take into consideration future development of adjoining properties.
(I) All street naming and numbering shall follow the Lake County, Indiana, grid system as recommended by the Fire Department or service.
(K) All newly developed streets or streets proposed for improvement shall be constructed with concrete curbs and gutters per town standards.
(L) Concrete pavements may be constructed as an alternative to asphalt with the approval of the Commission. Concrete pavement shall be constructed in accordance with the AASHTO Guide for Design of Pavement Structures. The soil testing results and design calculations prepared for this design method shall be submitted for review with the detailed street plans.
(M) Standard street name signs shall be provided and installed by the subdivider or developer at all street intersections, at the direction of the Commission. Location of street name signs shall be provided on the construction drawings.
(N) Traffic-control signs shall be provided and installed by the subdivider or developer. Traffic signs shall conform to the latest edition of the state Manual of Uniform Traffic-Control Devices. The Zoning Administrator will indicate the type and location of the required signs. Location of traffic control signs shall be provided on the construction drawings.
(O) A traffic impact study shall be required for all major subdivisions. The study shall be conducted in accordance with the Indiana Department of Transportation's Applicant's Guide to Traffic Impact Studies, latest edition. The study shall be provided to the Town Engineer for review prior to primary approval of the subdivision.
(P) Street name signs shall be installed upon the commencement of construction of any structure within a subdivision. Temporary signs may be used until such time as the first occupancy permit is issued, at which time permanent signs shall be installed. All street naming signs (other than temporary signs) shall be six inches in height, a minimum of 30 inches in length, double sided with words, with a forest green background with reflective white text on both sides with a letter and number size of three inches and a four-inch reflective town seal.

(Q) Addresses which are clearly visible from the street shall be placed on any structure while under construction.
