July 20, 2020 page 35 (3) All thoroughfares shall be properly related to specific traffic generators, such as industries, 1443 business districts, schools, churches, and shopping centers; to population densities; and to the 1444 pattern of existing and proposed land uses. 1445 (4) Roadways shall be laid out to conform as much as possible to the topography, to discourage use 1446 by through traffic, to permit efficient drainage and utility systems, and to require the minimum 1447 number of roadways necessary to provide convenient and safe access to property. 1448 (5) The gridiron roadway pattern need not necessarily be adhered to, and the use of curvilinear 1449 roadways or U-shaped roadways shall be encouraged where such use will result in a more 1450 desirable layout. 1451 (6) Cul-de-sacs shall be discouraged; proposed roadways shall be extended to the boundary lines of 1452 the tract to be subdivided unless prevented by topography or other physical conditions or unless 1453 in the opinion of the city such extension is not necessary or desirable for the coordination of the 1454 layout of the subdivision with the existing layout or the most advantageous future development 1455 of adjacent tracts. 1456 (7) In business and industrial developments, the roadways and other accessways shall be planned in 1457 connection with the grouping of buildings, location of rail facilities, and the provisions of alleys, 1458 truck loading and maneuvering areas, and walks and parking areas so as to minimize conflict of 1459 movement between the various types of traffic, including pedestrian. 1460 (c) Blocks. 1461 (1) Blocks should have sufficient width to provide for two tiers of lots of appropriate depths. 1462 Exceptions to this prescribed block width shall be permitted in blocks adjacent to arterial 1463 roadways, railroads or waterways. 1464 (3) In all blocks, the city shall require the reservation of an easement through the block to 1465 accommodate utilities, drainage facilities or pedestrian traffic. Pedestrian ways or crosswalks, not 1466 less than ten feet wide, may be required by the city through the center of blocks more than 800 1467 feet long where deemed essential to provide circulation of access to schools, playgrounds, 1468 shopping centers, transportation or other community facilities. Blocks designed for industrial uses 1469 shall be of such length and width as may be determined suitable by the city for prospective use. 1470 (d) Access to primary arterials. Where a subdivision borders on or contains an existing or proposed 1471 arterial, the city may require that access to such roadways be limited by one of the following means: 1472 (1) The subdivision of lots so as to back onto the arterials and front onto a parallel local or collector 1473 roadway; no access shall be provided from the arterial, and screening shall be provided in a strip 1474 of land along the rear property line of such lots. 1475 (2) A series of cul-de-sacs, U-shaped streets, or short loops entered from and designed generally at 1476 right angles to such a parallel street, with the rear lines of their terminal lots backing onto the 1477 arterial. 1478 (3) A marginal-access or service road separated from the arterial by a planting or grass strip and 1479 having access to the arterial at suitable points. 1480 (e) Road names and street addresses. The city shall name all roads at the time of preliminary subdivision 1481 approval and assign street addresses. Names shall be sufficiently different in sound and in spelling 1482 from other road names in the area so as not to cause confusion. A road which is or is planned as a 1483 continuation of an existing road shall bear the same name. 1484 (f) Road regulatory signs. All road signs shall be installed prior to issuance of building permits for any 1485 residence on the streets approved. The city shall place all signs at the developer's expense at all 1486
