(9) 
A table listing lot areas in square feet.
(10) 
Accurate location and description of monuments to be placed at corners and angles of all streets, at all curvature and points of tangency of curved streets, with accurate reference to some existing recognized governmental monument or marker.

[Amended 4-2-1990]
In addition to the above, the following shall be submitted as a part of the subdivision plan as a separate map and supporting data:
A. 
At least one test hole per lot, or more if there appears to be considerable variation in subsurface conditions, shall be dug to determine soil conditions for drainage. Seepage tests, made in accordance with the procedure recommended by the State Health Department, will be required in areas served by subsurface sewage disposal systems. The statement of a registered professional civil engineer or sanitary engineer showing results of these tests and soil conditions shall be attached.
B. 
The location of all existing and proposed sanitary and stormwater sewers, catch basins, manholes, bridges and culverts. Invert elevations of all drainage structures shall be shown.
C. 
Methods of proposed sanitary sewage, methods of stormwater drainage into existing sewers or into existing natural watercourses and methods of supplying water.
D. 
Final street plan with profiles drawn in ink on plan profile paper at scales of one inch equals 40 feet horizontally and one inch equals four feet vertically, one print on a stable transparent material and four black-line prints on white paper.
E. 
Contours in sufficient detail to show general topography, watercourses and drains. In general, contours shall be shown at no less than two-foot intervals, but in the case of relatively level land, the Commission may require contours of one-foot intervals. If grading of lots is to be carried out by the applicant, finished grades shall be shown. Slopes of 25% or greater shall be specifically delineated.
F. 
Wooded areas as indicated by foliage lines.
G. 
Flow-line elevations for all brooks shall be given at hundred-foot stations, and the location and size of all culverts shall be given.
H. 
The location of all soils classified as unstable by the United States Soils Conservation Service shall be identified, and the application shall specifically address areas subject to unusual erosion hazards due to such unstable soils or due to excessive stream velocity, lack of topsoil and vegetation or other causes.
I. 
Recognized landmarks, including stone walls, specimen trees (those exceeding 30 inches in caliper at the ground line) and other cultural and historical monuments.
J. 
Cultural and archaeological sites, including but not limited to those listed by the Connecticut Historical Commission.
K. 
Land areas along ridge lines, defined as areas lying within a distance of 1,000 feet on each side of the boundary line of a subregional watershed as defined on maps prepared by the Natural Resources Division, Connecticut Department of Environmental Protection.
[Added 4-2-1990]
A. 
The data required by Subsection E and successive subsections of § A184-20 shall be prepared for land areas adjacent to and within 100 feet of the subdivision site, or for a greater distance where necessary for proper evaluation of the development proposal's impact on these resources on and off the site.[1]

Editor's Note: Amended during codification.
B. 
Where any subdivision application includes any of the data specified in Subsection E and successive subsections of A184-20, the application shall include a narrative evaluating the relative importance to the site and to its environs of each area, site or object so identified. The subdivision shall be designed to reduce the adverse impacts on such areas, sites and objects as much as is possible. The Commission may require the redesign of subdivision features, including roads, lot lines, lot areas, location and scale of structures and location of reserved open space areas, in order to further reduce the adverse impact of the subdivision on these areas, sites and objects. The Commission may also require correction of preexisting unstable conditions on the site, such as steep banks, drainage ditches or eroding slopes. Where the Commission determines that it is necessary to protect such areas, sites or objects from the adverse impacts of development, it may require they be made the subject of negative easements in a form approved by the Corporation Counsel and recorded in the Town land records.
If more than one sheet is required to show the entire subdivision, one print on a stable tracing material and four black-line prints on white paper of a map showing the entire street system at a scale of one inch equals 100 feet shall also be submitted.
Where all land proposed for development or land under ownership of an applicant is not included in the proposal, a master development sketch shall accompany the original submission. This sketch, at a scale of not less than one inch equals 100 feet, shall show proposed rights-of-way and lot layout. Additional information may be required by the Commission where any part of the subdivision would be affected by development of another part. Sections in the proposed order of development shall be labeled with Roman numerals, and each section shall be applied for and processed individually.
