A. 
In considering applications for subdivision of land, the Planning Board shall be guided by the standards set forth below. These standards shall be considered to be minimum requirements and shall be waived by the Planning Board only under circumstances set forth in Article VII herein.
B. 
The Design Criteria and Construction Specifications for Land Development of the Town of Caledonia are adopted herein by reference and shall establish the standard for subdivision design and construction.[1]
[1]
Editor's Note: The Design Standards are on file in the Town Clerk's office.
A. 
Character of land. Land to be subdivided shall be of such character that it can be used safely for building purposes without danger to health or peril from fire, flood or other menace.
B. 
Conformity to Official Map and Master Plan. Subdivisions shall conform to the Official Map of the Town and shall be in harmony with the Master Plan, if such exists.
C. 
Specifications for required improvements. All required improvements shall be constructed or installed to conform to the Town specifications, which are contained in the Design Criteria and Construction Specifications.
A. 
Width, location and construction. Streets shall be of sufficient width, suitably located and adequately constructed to conform with the Master Plan, if such exists, and to accommodate the prospective traffic and afford access for fire-fighting, snow removal and other road maintenance equipment. The arrangement of streets shall be such as to cause no undue hardship to adjoining properties and shall be coordinated so as to compose a convenient system.
B. 
Arrangement. The arrangement of streets in the subdivision shall provide for the continuation of principal streets of adjoining subdivisions and for proper projection of principal streets into adjoining properties which are not yet subdivided, in order to make possible necessary fire protection, movement of traffic and the construction or extension, presently or when later required, of needed utilities and public services, such as sewers, water and drainage facilities. Where, in the opinion of the Caledonia Planning Board, topographic or other conditions make such continuance undesirable or impracticable, the above conditions may be modified.
C. 
Minor streets. Minor streets shall be so laid out that their use by through traffic will be discouraged.
D. 
Special treatment along major arterial streets. When a subdivision abuts or contains an existing or proposed major arterial street, the Board may require marginal access streets, reverse frontage with screen planting contained in a nonaccess reservation along the rear property line, deep lots with rear service alleys or such other treatment as may be necessary for adequate protection of residential properties and to afford separation of through and local traffic.
E. 
Provision for future resubdivision. Where a tract is subdivided into lots substantially larger than the minimum size required in the zoning district in which a subdivision is located, the Board may require that streets and lots be laid out so as to permit future resubdivision in accordance with the requirements contained in these regulations.
F. 
Dead-end streets. The creation of dead-end or loop residential streets will be encouraged wherever the Board finds that such type of development will not interfere with normal traffic circulation in the area. In the case of dead-end streets, where needed or desirable, the Board may require the reservation of a twenty-foot-wide easement to provide for continuation of pedestrian traffic and utilities to the next street.
G. 
Block size. Blocks generally shall not be less than 400 feet nor more than 1,200 feet in length. In general, no block width shall be less than twice the normal lot depth. In blocks exceeding 800 feet in length, the Board may require the reservation of a twenty-foot-wide easement through the block to provide for the crossing of underground utilities and pedestrian traffic where needed or desirable and may further specify, at its discretion, that a four-foot-wide paved footpath be included.
H. 
Intersections with collector or major arterial streets. Minor or secondary street openings into intersections with collector or major arterial streets shall, in general, be at least 500 feet apart.
I. 
Street jogs. Street jogs with center line offsets of less than 125 feet shall be avoided.
J. 
Angle of intersection. In general, all streets shall join each other so that for a distance of at least 100 feet the street is approximately at right angles to the street it joins, and in no case shall the angle of intersection be less than 75° without additional channelization.
K. 
Relation to topography. The street plan of a proposed subdivision shall bear a logical relationship to the topography of the property, and all streets shall be arranged so as to obtain as many of the building sites as possible at or above the grade of the streets. Grades of streets shall conform as closely as possible to the original topography.
L. 
Other required streets. Where a subdivision borders on or contains a railroad right-of-way or limited access highway right-of-way, the Planning Board may require a street approximately parallel to and on each side of such right-of-way, at a distance suitable for the appropriate use of the intervening land (as for park purposes in residential districts or for commercial or industrial purposes in appropriate districts). Such distance shall also be determined with due regard for the requirements of approach grades and future grade separations.
A. 
General. Subdivision plats and other developments shall provide for all other customary elements of street construction and utility service which may be appropriate in each locality as determined by the Planning Board upon consultation with the Municipal Engineer. Such elements may include but shall not be limited to street pavement, gutters, stormwater, inlets, manholes, curbs, sidewalks, streetlighting standards, water mains, fire hydrants, fire alarm signal devices and sanitary sewers. Underground utilities within the street right-of-way shall be located as required by the Municipal Engineer, and underground service connections to the property line of each lot shall be installed before the street is paved. All street improvements and other construction features of the subdivision shall conform to municipal specifications which may be established from time to time and shall be subject to approval as to design, specifications and construction by the Municipal Engineer. See Section I.4 of Design Criteria (pages 24-31) for more specific requirements, criteria and standards.[1]
[1]
Editor's Note: The Design Criteria are on file in the Town Clerk's office.
B. 
Widths of rights-of-way.
(1) 
The Caledonia Planning Board shall be guided by the following roadway widths and standards:
Type of Street
Minimum Right-of-Way
(feet)
Minimum Pavement
(feet)
Arterial
80
40
Collector
70
24
Minor
60
20
(2) 
When not indicated on the Master Plan, the classification of streets shall be determined by the Planning Board.
C. 
Improvements. Streets shall be graded and improved with pavements, curbs, gutters, sidewalks, storm drainage facilities, water mains, sewers, streetlights and signs, street trees and fire hydrants, except where waivers may be requested, and the Board may waive, subject to appropriate conditions, such improvements as it considers may be omitted without jeopardy to the public health, safety and general welfare. Pedestrian easements shall be improved as required by the Planning Board. Such grading and improvements shall be approved as to design and specifications by the Town Engineer.
(1) 
Fire hydrants. Installation of fire hydrants shall be in conformity with all requirements of standard thread and nut as specified by the New York Fire Insurance Rating Organization and the Division of Fire Safety of the State of New York.
(2) 
Streetlighting facilities. Lighting facilities shall be in conformance with the lighting system of the Town. Such lighting standards and fixtures shall be installed after approval by the appropriate power company and the authorized Town Electrical Inspector.
D. 
Utilities in streets. The Planning Board shall, wherever possible, require that underground utilities be placed in the street right-of-way between the paved roadway and street line. The subdivider shall install underground service connections to the property line of each lot within the subdivision for such required utilities before the street is paved.
E. 
Utility easements. Where topography is such as to make impractical the inclusion of utilities within the street rights-of-way, perpetual unobstructed easements of at least 20 feet in width shall be otherwise provided with satisfactory access to the street. Wherever possible, easements shall be continuous from block to block and shall present as few irregularities as possible. Such easements shall be cleared and graded where required.
F. 
Grades. Grades of all streets shall conform in general to the terrain and shall not be less than 1/2% nor more than 6% for collector streets, or 10% for minor streets in residential zones, but in no case more than 3% within 50 feet of any intersection.
G. 
Changes in grade. All changes in grade shall be connected by vertical curves of such length and radius as meet with the approval of the Town Engineer so that clear visibility shall be provided for a safe distance.
H. 
Curve radii at street intersections. All street right-of-way lines at intersections shall be rounded by curves of at least 20 feet radius and curbs shall be adjusted accordingly.
I. 
Steep grades and curves; visibility of intersections. A combination of steep grades and curves shall be avoided. In order to provide visibility for traffic safety, that portion of any corner lot, whether at an intersection entirely within the subdivision or of a new street with an existing street, which is shown shaded on Sketch A shall be cleared of all growth (except isolated trees) and obstructions above the level of three feet higher than the center line of the street. If directed, ground shall be excavated to achieve visibility.
J. 
Dead-end streets (culs-de-sac). Where dead-end streets are designed to be so permanently, they should, in general, not exceed 500 feet in length and shall terminate in a circular turnaround having a minimum right-of-way radius of 60 feet and pavement radius of 50 feet. At the end of temporary dead-end streets, a temporary turnaround with a pavement radius of 50 feet shall be provided, unless the Planning Board approves an alternate arrangement.
K. 
Watercourses.
(1) 
Where a watercourse separates a proposed street from abutting property, provision shall be made for access to all lots by means of culverts or other structures of a design approved by the Town Engineer.
(2) 
Where a subdivision is traversed by a watercourse, drainageway, channel or stream, there shall be provided a stormwater easement or drainage right-of-way as required by the Town Engineer, and in no case less than 20 feet.
L. 
Curved radii. In general, street lines within a block, deflecting from each other at any one point by more than 10°, shall be connected with a curve, the radius of which for the center line of the street shall not be less than 400 feet on arterial streets, 200 feet on collector streets and 100 feet on minor streets.
M. 
Service streets or loading space in commercial development. Paved rear service streets of not less than 20 feet in width, or in lieu thereof, adequate off-street loading space, suitably surfaced, shall be provided in connection with lots designed for commercial use.
N. 
Free flow or vehicular traffic abutting commercial developments. In front of areas zoned and designed for commercial use, or where a change of zoning to a zone which permits commercial use is contemplated, the street width shall be increased by such amount on each side as may be deemed necessary by the Planning Board to assure the free flow of through traffic without interference by parked or parking vehicles and to provide adequate and safe parking space for such commercial or business district.
A. 
Lots to be buildable. In addition to lots meeting the requirements of Chapter 130, Zoning, the Planning Board will utilize the environmental review process under SEQR to take under advisement the many factors which may determine the suitability of a lot or lots for building purposes.
B. 
Side lines. All side lines of lots shall be at right angles to straight street lines and radial to curved street lines, unless a variance from this rule will give a better street or lot plan.
C. 
Corner lots. In general, corner lots should be larger than interior lots to provide for proper building setback from each street and provide a desirable building site.
D. 
Driveway access. Driveway access and grades shall conform to specifications of the Town Driveway Ordinance, if one exists. Driveway grades between the street and the setback line shall not exceed 10%.
E. 
Access from private streets. Access from private streets shall be deemed acceptable only if such streets are designed and improved in accordance with these regulations.
F. 
Monuments and lot corner markers. Permanent monuments meeting specifications approved by the Town Engineer as to size, type and installation shall be set at such block corners, angle points, points of curves in streets and other points as the Town Engineer may require, and their location shall be shown on the subdivision plat.
G. 
Additional design requirements. Additional design requirements shall be as follows:
(1) 
The lot size, width, depth, shape, orientation and the minimum building setback lines shall be appropriate for the location of the subdivision and for the type of development and use contemplated.
(2) 
All lots shown on the final plat must conform to the minimum requirements of Chapter 130, Zoning, as to area and dimensions for the zone in which the subdivision is located.
(3) 
Where extra width has been dedicated for widening of existing streets, lots shall begin at such extra-width line, and all setbacks shall be measured from such line.
(4) 
Where there is a question as to the suitability of a lot or lots for their intended use due to factors such as rock formations, flood conditions or similar circumstances, the Planning Board may, after adequate investigation, require modification of such lots.
(5) 
Block length and width or acreage within bounding roads shall be such as to accommodate the size of lot required in the area by Chapter 130, Zoning, and to provide for convenient access, circulation control and safety of street traffic.
(6) 
Easement dedications for nonsurface or nonstructural uses including underground utility lines or drainageways may be credited toward minimum allowable lot area, provided that operation and maintenance of the facilities shall remain unimpaired and the area of the easement comprises a usable portion of the lot.
(7) 
Minimum lot width shall normally be measured at the edge of the road right-of-way. The minimum lot width shall also apply to the width at the setback or building line. The Planning Board shall have authority to interpret lot width and average lot depth for unusually shaped or situated lots.
A. 
General.
(1) 
Storm drainage facilities shall be designed to take the runoff from streets, lawns, paved areas and roof areas. Full engineering attention shall be given to the interception and conveyance of stormwater by the street drainage system, a system of back-lot-line drainage swales and main drainage channels through the development. In order to facilitate drainage, no street grades shall be less than 0.5%.
(2) 
In general, the preservation of natural watercourses is preferable to the construction of drainage channels, and wherever practicable such natural watercourses should be preserved. The overall objective of a drainage plan shall be to:
(a) 
Limit the rate of storm runoff from the project site to no more than the original or natural rate of runoff.
(b) 
Limit, to the maximum extent possible, the pollution of existing surface and subsurface bodies of water via storm runoff and/or percolation systems.
(3) 
Attention is called to the possibilities of using easements for natural watercourses to preserve open space. Storm sewers and other hydraulic structures and channels shall be sized based upon a design flow with a minimum return interval of 10 years. The design of natural watercourse channels shall depend upon the drainage area according to the following table.
B. 
Design return intervals for natural watercourses.
Design Return Intervals for Natural Watercourses

(square miles)
Recurrence Interval
(years)
Above 20
100
Between 4 and 20

C. 
Erosion control. In order to assure that the surrounding land and watercourses will not be subjected to siltation or erosion, the Planning Board shall require the developer to follow certain erosion control practices as it deems necessary. The developer shall consult with the Municipal Engineer to determine whether or not the required procedures are to be put into practice. Such procedures may include:
(1) 
Installing and maintaining temporary sedimentation basins at the point or points of stormwater discharge from the property.
(2) 
Exposing the smallest practical area of land at any one time during development.
(3) 
Provision for temporary vegetation and/or mulching to protect critical areas.
(4) 
Provision for adequate drainage facilities to accommodate effectively the increased runoff caused by changed soil and surface conditions during and after development.
(5) 
Fitting of the development plan to the topography and soils, so as to minimize the erosion potential.
(6) 
Retention and protection of natural vegetation wherever possible.
(7) 
Installation of permanent final vegetation and structures as soon as practicable.
(8) 
Provision of adequate protective measures when slopes in excess of 10% are graded and minimizing such steep grading.
(9) 
Provision for interceptor swales and sedimentation basins along the lower edges of all developments, and these shall be shown on the plans.
(10) 
Limitation of land clearing to dryer months of the year.
D. 
Flood hazard prevention.
(1) 
Flood hazard prevention shall include the control of soil erosion of land surface and drainage channels and the prevention of inundation and excessive groundwater seepage by comprehensive site grading and the establishment of adequate elevations of buildings, building openings and roadways above the observed, anticipated or computed water levels of storm sewers, streams, channels, floodplains, detention basins and swales.
(2) 
All development proposed within the special flood hazard area, as defined by the Federal Insurance Administration, shall comply with the various regulations set forth by the Federal Insurance Administrator. (See Clerk for details).[1]
[1]
Editor's Note: See Ch. 74, Flood Damage Prevention.
(3) 
Development within or adjacent to the floodplain shall comply with current zoning, local laws and regulations.
(4) 
Particular attention shall be paid to development in the vicinity of Genesee River and Spring Creek and their floodplains, and no alteration of the existing characteristics of the areas shall take place without the specific approval of the municipality as to the adequacy of the protective measures taken, if any, and the effects of such development on upstream and downstream reaches of the watercourse and adjacent properties.
E. 
Stormwater detention basins. The municipality has determined it to be desirable to require stormwater detention basins in certain areas. There are various reasons for this, not the least of which is that continual upstream development overtaxes downstream natural watercourses as well as man-made drainage facilities. Secondly, these increased rates of stormwater runoff cause environmental problems downstream, such as highly erosive velocities, flooding and over-topping of the banks. Consequently it has been determined advisable to insist upon retention basins where appropriate and to have these retention basins designed in a manner compatible with the particular problem. Please see Section I.8 (pages 39-42) of Design Criteria for additional considerations and specifics on this subject.[2]
[2]
Editor's Note: The Design Criteria are on file in the Town Clerk's office.
F. 
Stormwater ground recharge. The New York State Department of Environmental Conservation may place certain constraints on systems using ground recharge of stormwater. Some of the possible constraints (but not limited to these) are:
(1) 
Discharge shall not take place into or within four feet above bedrock or the groundwater table.
(2) 
Stormwater may be required to be treated prior to discharge.
(3) 
The system may need periodic service to maintain the designed permeability and prevent failure. See Section I.9 (page 42) of Design Criteria for additional considerations.
G. 
Accommodations for house and lot storm drainage. Finished ground level adjacent to house foundation walls shall be a minimum one foot zero inches higher than the edge of pavement for standard subdivision development. In one- or two-lot subdivisions where front lot setbacks exceed 150 feet and/or where natural drainage characteristics would be better utilized by draining away from the street, this requirement may be waived. In any case, provisions shall be made for draining positively the surface of each lot by proper grading and the construction of swales, ditches or drains. These items shall receive the same careful design attention as the street drainage system. Also see Section I.12 (page 47) of Design Criteria for additional instructions.[3]
[3]
Editor's Note: The Design Criteria are on file in the Town Clerk's office.
H. 
Removal of spring and surface water. The subdivider may be required by the Planning Board to carry away by pipe or open ditch any spring or surface water that may exist either previous to or as a result of the subdivision. Such drainage facilities shall be located in the street right-of-way where feasible or in perpetual unobstructed easements of appropriate width.
I. 
Drainage structure to accommodate potential development upstream. A culvert or other drainage facility shall, in each case, be large enough to accommodate potential runoff from its entire upstream drainage area, whether inside or outside the subdivision. The Town Engineer shall approve the design and size of the facility based on anticipated runoff from a ten-year storm under conditions of total potential development permitted by the Chapter 130, Zoning, in the watershed. The Town shall share the cost of culverts larger than that which is required to properly service the subdivision.
J. 
Responsibility from drainage downstream. The subdivider's engineer shall also study the effect of each subdivision on the existing downstream drainage facilities outside the area of the subdivision; this study shall be reviewed by the Town Engineer. Where it is anticipated that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility during a five-year storm, the Planning Board shall notify the Town Board of such potential conditions. In such case, the Planning Board shall not approve the subdivision until provision has been made for the improvement of said condition.
K. 
Land subject to flooding. Land subject to flooding or land deemed by the Board to be uninhabitable shall not be platted for residential occupancy nor for such other uses as may increase the danger to health, life or property or aggravate the flood hazard, but such land within the plat shall be set aside for such uses as shall not be endangered by periodic or occasional inundation or improved in a manner satisfactory to the Board to remedy said hazardous conditions.
A. 
The municipality has jurisdiction over all water mains, permits and appurtenances. Concurrent with the submission of the preliminary plan, the developer shall submit a data sheet providing sufficient calculations relating to static and residual pressure, date of flow tests, recorded flow, description of existing water mains and a discussion on anticipated fire protection and domestic pressures and volumes within the development.
B. 
The waterlines and appurtenances shall be designed in accordance with the standards set forth by the municipality.
C. 
These facilities shall be subject to the approval of the municipal representative during all stages of design and construction.
D. 
The criterion of design will normally be that pipes shall be sized to obtain the required fire flow at the critical point in the development while satisfying the average daytime domestic draft.
E. 
Fire hydrants shall not be spaced greater than 500 feet apart.
F. 
Where public waterlines are installed, all such waterlines shall be located between the curbline and the property line within any street right-of-way.
G. 
Where public water is not available, the developer may be required to install fire suppression ponds or similar on-site storage to aid fire protection.
A. 
General specifications. Until sanitary sewers become available in Caledonia, septic tanks and leach fields shall be considered alternative methods of treatment in proposed new developments, but because all sources of water supply come from public or private well systems, extra safeguards and higher standards may need to be employed to protect public health and the natural environment. Among other things, this may require lower densities of development than would normally be required.
B. 
Septic tanks and leach beds. Such facilities shall be designed in accordance with current policies and directives of the New York State Department of Environmental Conservation (NYSDEC) and the New York State Health Department and the standards set forth in Section I.10.11 (pages 45 and 46) of the Design Criteria.[1]
[1]
Editor's Note: See Design Criteria on file in the Town Clerk's office.
A. 
All utilities shall be underground, including electric, telephone and cable television. This regulation shall be enacted in accordance with the New York State Public Service Commission ruling (tariffs) for all public utilities. Utility companies shall obtain the necessary approvals and permits prior to starting construction.
B. 
Easements across lots or centered on rear or side lot lines shall be provided for utilities, where necessary, and shall be at least 20 feet wide. Where multiple utilities are present, they shall be 30 feet wide. Easements along common property lines may be split evenly between adjacent lots.
A. 
It shall be the responsibility of the developer to furnish easements to the municipality, as required, for the installation and permanent operation of drains, sewers, mains or access roads where required.
B. 
These easements shall be prepared prior to the approval of the detailed plan and be so written as to be contingent upon the municipal approval of said plan.
C. 
It shall be the responsibility of the developer to determine if off-site easements are necessary for the proper discharge of stormwater onto private property downstream from the proposed development site.
D. 
Where a development is traversed by a watercourse, drainageway, channel or stream, or contains a pond which crosses a property line, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the line of such watercourse and of such width as will be adequate to preserve natural drainage and to accommodate the twenty-five-year flood area of such watercourse. In no case shall the easement be less than 20 feet in width. Piping of the watercourse may be provided.
The developer shall take all necessary measures to control dust resulting from his operations and to prevent spillage of excavated material on public roads. When directed by the Code Enforcement Officer, the developer shall apply calcium chloride and/or water where directed and in such quantities and at such frequencies as may be required to control such dust and prevent it from becoming a nuisance to the surrounding area.
A. 
Recreation areas shown on Town Plan. Where a proposed park, playground or open space shown on the Town Plan is located in whole or in part in a subdivision, the subdivider shall show such areas on the plat in accordance with the requirements specified in Subsection B below and notify the Town Board. Such area or areas may be dedicated to the Town or county by the subdivider if the Town Board approves such dedication.
B. 
Parks and playgrounds not shown on Town Plan.
(1) 
The Planning Board shall require that the subdivider reserve sites of a character, extent and location suitable for the development of a park, playground or other recreational purpose. For a major subdivision, each reservation shall be of an area equal to 5% of the total land within the subdivision, but in no case shall a reservation be less than two acres. The area to be preserved shall possess the suitable topography, general character and adequate road access necessary for its recreational purposes.
(2) 
Where the Planning Board requires land to be set aside for parks, playgrounds or other recreational purposes, the Board shall require that the site be graded, loamed and seeded and may require it to be fenced.
C. 
Waiver of plat designation of area for parks and playgrounds.
(1) 
In cases where the Planning Board finds that, due to the size, topography or location of the subdivision, land for park, playground or other recreation purpose cannot be properly located therein, or, if in the opinion of the Board it is not desirable, the Board may waive the requirement that the plat show land for such purpose. In lieu of dedicating land for such purposes, the Board shall then require as a condition of approval of the plat a payment to the Town as indicated on the fee schedule.[1] The amount of land which otherwise would have been acceptable as a recreation site shall be determined in accordance with the standards set forth in Subsection B of this section.
[1]
Editor's Note: The fee schedule is on file in the Town Clerk's office.
(2) 
Such amount shall be paid to the Town Board at the time of final plat approval, and no plat shall be signed by the authorized officer of the Planning Board until such payment is made. All such payments shall be held by the Town Board in a special Town Recreation Site Acquisition and Improvement Fund to be used for the acquisition of land that:
(a) 
Is suitable for permanent park, playground or other recreational purposes.
(b) 
Is so located that it will serve primarily the general neighborhood in which the land covered by the plat lies.
(c) 
Shall be used only for park, playground or other recreational land acquisition or improvements.
(3) 
Such money may also be used for the physical improvement of existing parks or recreation areas serving the general neighborhood in which the land shown on the plat is situated, provided that the Planning Board finds there is need for such improvements.
D. 
Reserve strips prohibited. Reserve strips of land, which might be used to control access from the proposed subdivision to any neighboring property or to any land within the subdivision itself, shall be prohibited.
E. 
Preservation of natural features. The Planning Board shall, wherever possible, establish the preservation of all natural features which add value to residential developments and the community, such as large trees or groves, topsoil, watercourses and falls, wetlands, beaches, historic spots, vistas and similar irreplaceable assets. This will include the following requirements:
(1) 
Topsoil moved during the course of construction shall be redistributed so as to provide at least six inches of cover to all areas of the subdivision and shall be stabilized by seeding or planting. At no time shall topsoil be removed from the site without written permission from the Caledonia Planning Board.
(2) 
To the fullest extent possible, all existing trees and shrubbery shall be conserved by the subdivider. Special consideration shall be given to the arrangement and ultimate improvement or development of the lots to this end. Precautions shall also be taken to protect existing trees and shrubbery during the process of grading the lots and roads. Where there is a question as to the desirability of removing a group of trees, which serve to add interest and variety to the proposed subdivision, in order to allow for use of the land for a lot or lots, the Planning Board may, after proper investigation, require modification of such lots. Where any land other than that included in public rights-of-way is to be dedicated to the public use, the developer shall not remove any trees from the site without written permission from the Caledonia Planning Board.
(3) 
Where a subdivision is traversed by a natural lake, pond or stream, the boundaries or alignment of said watercourse shall be preserved unless, in the opinion of the Planning Board, a change or realignment will enhance the development and beauty of the subdivision or the utilization of such features by the future residents of the subdivision. All proposed changes in watercourse alignment shall be in accordance with the revised New York State Stream Conservation Law.
(4) 
Unique physical features, such as historic landmarks and sites, rock outcroppings, mature trees, hilltop lookouts, desirable natural contours and similar features, shall be preserved if possible.
(5) 
The subdivider shall not be permitted to leave any surface depressions which will collect pools of water, except those which are designed as stormwater detention facilities to serve the needs of the subdivision. Stormwater detention facilities shall be designed in conformance with the Town of Caledonia Design Criteria and Construction Specifications and shall be in harmony with other natural features of the site.
(6) 
The subdivider shall not be permitted to leave any mounds of dirt around the tract. All surfaces shall be restored within six months of the time of the completion of the section of the subdivision.
(7) 
All land clearing and grading plans and practices shall be consistent with the Design Criteria and Construction Specifications.
F. 
Floodplain.
(1) 
Mapping. If any portion of the land within the subdivision is subject to inundation or flood hazard by stormwater, such fact and portion shall be clearly indicated on the preliminary plat and the prominent note on each sheet of such map whereon any such portion shall be shown.
(2) 
Use. Land subject to flooding, and land deemed by the Planning Board to be otherwise uninhabitable, shall not be platted for residential occupancy nor for such other uses as may increase danger to health, life or property or aggravate the flood hazard.
The owner may place restrictions on the development greater than those required by Chapter 130, Zoning. Such restrictions, if any, shall be indicated on the final subdivision plat.
