Measure PP is not clear whether it considers a street a structure and, therefore, if the grading and construction for a street or road is subject to the slope and ridgeline standards of Measure PP. City policy is to generally design streets or roads with a maximum grade of 10- to 15-percent, which can be constructed on land exceeding a 25-percent slope through grading and the use of retaining walls. However, streets or roads on hillside property involve visible cut and fill slopes that may not match surrounding terrain; the alteration of drainage features; the installation of surface and sub-surface structures such as "V"-ditches; and the construction of retaining walls; etc., any of which could be determined to be a "structure".

(The following options and narrative considers roads to include the paved curb-to-curb section and their attendant infrastructure such as retaining walls, drainage features, etc.) • Option One: Determine that streets and roads and their attendant infrastructure are not structures and, therefore, are exempt from Measure PP. Such an interpretation would not preclude the City's discretionary review authority whereby the proposed street or road can be prohibited due to design concerns and any related impacts, but would allow roads to be constructed on 25-percent slopes. • Option Two: Determine that streets and/or roads and their attendant infrastructure are structures in that they are physical improvements on the property intended to 11
