1. Classification. In accordance with the Comprehensive Development Plan for the Town of Sebago and for the purposes of these Standards, streets are classified by function, as follows:

(b) Collector Streets-serve as feeder streets to arterial streets, as collectors of traffic from minor streets, and for circulation and access in commercial and industrial areas.

2.2 All streets in the subdivision shall be so designed that, in the opinion of the Board, they shall provide safe vehicular travel while discouraging movement of through traffic.

2.3 The arrangement, character, extent, width, grade and location of all streets shall be considered in their relation to existing or planned streets, to topographical conditions, to public convenience and safety, and their appropriate relation to the proposed use of the land to be served by such streets. Grades of streets shall conform as closely as possible to the original topography within the limits of these Standards.

2.5 Subdivisions containing twenty (20) lots or more or having area in excess of thirty-five (35) acres shall have at least two (2) street connections with existing public streets for streets on an approved subdivision plan for which a bond has been filed.

2.6 Street and driveway entrances onto existing or proposed collector streets shall not exceed a frequency of one per four hundred (400) feet of street frontage. Driveway and street entrances onto existing or proposed arterial streets shall not exceed a frequency of one per one thousand (1000) feet of street frontage.

3.1 All streets in a subdivision shall be designed and constructed to meet the following Standards for streets according to their classification as determined by the Board.

3.2 Grades of all streets shall conform in general to the terrain, and shall not be less than one-half (1/2) of one percent nor more than 6% for collector streets, or 8% for minor streets in residential subdivisions, but in no case more than 3% within fifty (50) feet of any intersection.

3.3 All changes in grade shall be connected by vertical curves of such length and radius as meet with the approval of the Board so that clear visibility shall be provided for a distance of two hundred (200) feet.

3.4 Intersections of streets shall be at angles as close to ninety (90) degrees as possible and in no case shall two (2) streets intersect as an angle smaller than sixty (60) degrees. To this end where one street approaches another between 60-90 degrees, the former street should be curved approaching the intersection.

3.5 Cross street intersections (four-cornered)shall be avoided insofar as possible, except as shown on the Comprehensive Plan or at other important traffic intersections. A distance of at least two hundred (200) feet shall be maintained between center lines of offset intersecting streets.

3.6 Street intersections and curves shall be so designed as to permit adequate visibility for both pedestrian and vehicular traffic. If directed, ground shall be excavated to achieve visibility.

3.7 A dead-end street or cul-de-sac shall not exceed 600 feet in length and shall be provided with a suitable turn-around at the closed end having a minimum outside curb radius of sixty-five (65) feet.

3.8 All streets shall be provided with adequate drainage facilities to provide for the removal of storm water to prevent flooding of the pavement and erosion of adjacent surfaces.

3.9 Side slopes in cuts or fills shall not be steeper than three (3) feet horizontal and one (1) foot vertical, graded, loamed (2” to 4” compacted) as directed by the engineer appointed by the Board and seeded as required.
