(4) Roof forms should generally include traditional styles such <br />as hip and/or gable. Flat and shed roofs should only be <br />used for minor design elements, such as porches and <br />dormers. Mansard and dome roofs are not appropriate. <br />(5) Buildings should be designed for consistency of massing, <br />proportions, details , materials, and colors on all exterior <br />walls. <br />(6) Building feature proportions (i.e., doors , windows, entries , <br />roof forms, wall massings, etc.) should be carefully <br />balanced. One-story entries are strongly encouraged while <br />entries exceeding one-and-one-half stories should be <br />prohibited. <br />(7) Careful design attention should be given to details around <br />doors, windows, eaves, etc. <br />(8) The first-floor elevation above finished grade should be <br />minimized to reduce overall building height. <br />c) Grading <br />(1) Grading for buildings, driveways, outdoor-use areas, etc. <br />should be compatible with existing topographic contours <br />and minimized to preserve the natural topography of the <br />site. <br />(2) Graded slopes should utilize "rounded landform grading" <br />techniques to achieve a natural transition between graded <br />areas and existing terrain (see Figure IV-3). Flat graded <br />planes and sharp angles of intersection should be avoided <br />to reduce the visual impact of grading . <br />(3) Site grading should be used to screen buildings and reduce <br />the visual mass of buildings, wherever applicable. <br />(4) Substantial graded areas of uniform slope in hillside areas <br />should be avoided. Cut and fill slopes should generally <br />undulate and vary in slope gradient. <br />(5) Tennis courts should not be permitted on existing slopes <br />which exceed seven percent. <br />31
