July 20, 2020 page 47 (3) All thoroughfares shall be properly related to specific traffic generators, such as industries, 1986 business districts, schools, churches, and shopping centers; to population densities; and to the 1987 pattern of existing and proposed land uses. 1988 (4) Roadways shall be laid out to conform as much as possible to the topography, to discourage use 1989 by through traffic, to permit efficient drainage and utility systems, and to require the minimum 1990 number of roadways necessary to provide convenient and safe access to property. 1991 (5) The gridiron roadway pattern need not necessarily be adhered to, and the use of curvilinear 1992 roadways or U-shaped roadways shall be encouraged where such use will result in a more 1993 desirable layout. 1994 (6) Culs-de-sacs shall be discouraged; proposed roadways shall be extended to the boundary lines 1995 of the tract to be subdivided unless prevented by topography or other physical conditions or unless 1996 in the opinion of the city such extension is not necessary or desirable for the coordination of the 1997 layout of the subdivision with the existing layout or the most advantageous future development 1998 of adjacent tracts. 1999 (7) In business and industrial developments, the roadways and other accessways shall be planned in 2000 connection with the grouping of buildings, location of rail facilities, and the provisions of alleys, 2001 truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of 2002 movement between the various types of traffic, including pedestrian. 2003 (c) Blocks. 2004 (1) Blocks shall should have sufficient width to provide for two tiers of lots of appropriate depths. 2005 Exceptions to this prescribed block width shall be permitted in blocks adjacent to arterial 2006 roadways, railroads or waterways. 2007 (2) The lengths, widths, and shapes of blocks shall be such as are appropriate for the locality and 2008 the type of development contemplated; but block lengths in residential areas shall not exceed 2009 1,500 feet or 12 times the minimum lot width required in the zoning district, nor be less than 400 2010 feet in length from centerline to centerline of adjacent streets. Wherever practicable, blocks along 2011 arterial collector roadways shall be not less than 1,000 feet in length. 2012 (3) In all blocks, the city shall require the reservation of an easement through the block to 2013 accommodate utilities, drainage facilities or pedestrian traffic. Pedestrian ways or crosswalks, not 2014 less than ten feet wide, may be required by the city through the center of blocks more than 800 2015 feet long where deemed essential to provide circulation of access to schools, playgrounds, 2016 shopping centers, transportation or other community facilities. Blocks designed for industrial uses 2017 shall be of such length and width as may be determined suitable by the city for prospective use. 2018 (d) Access to primary arterials. Where a subdivision borders on or contains an existing or proposed 2019 arterial, the city may require that access to such roadways be limited by one of the following means: 2020 (1) The subdivision of lots so as to back onto the arterials and front onto a parallel local or collector 2021 roadway; no access shall be provided from the arterial, and screening shall be provided in a strip 2022 of land along the rear property line of such lots. 2023 (2) A series of culs-de-sacs, U-shaped streets, or short loops entered from and designed generally at 2024 right angles to such a parallel street, with the rear lines of their terminal lots backing onto the 2025 arterial. 2026 (3) A marginal-access or service road separated from the arterial by a planting or grass strip and 2027 having access to the arterial at suitable points. 2028 (e) Road names and street addresses. The sketch plan as submitted shall not indicate any names upon 2029 proposed streets. The city shall name all roads at the time of preliminary subdivision approval and 2030 Commented [JB114]: Not how Orono has developed.
