The following policies apply to drainage studies required to be submitted to the town for approval. When applicable, exceptions to these policies may be made in writing at the discretion of the Town Engineering Department under special conditions.
(A) It is the policy of the town that each type of development and improvement project requires a drainage evaluation. Each drainage evaluation requires submittal of a report documenting the findings and results of that evaluation to the Town Engineer for review and possible approval. The submittal review process is described in § 152.12.
(B) There are nine types of drainage report submittals covering different types of developments defined for the town review process. The types of report submittals, and the corresponding types of development, are shown in Table 2.1. A description of each type of report submittal is described in § 152.13.
(C) All drainage reports produced for projects within the town shall reference the Drainage Master Plan for Town of Payson, Gila County, Arizona (2001) (PDMP), latest revision, and describe how the results of that plan affect the project in question.
(D) The appropriate sections of the UDC, latest revision adopted by the town, shall apply as appropriate and deemed necessary by the town.
(E) The town recommends discussing all proposed drainage submittals with town staff prior to preparing and submitting a drainage report for review. Any drainage evaluation submitted to the town for review and possible approval must be prepared and sealed by a Professional Civil Engineer licensed to practice within the State of Arizona. The only exception is an individual non-hillside single family residential lot without modifications to a drainage way.
(F) A property owner shall not modify the manner in which or location where storm water enters or exits the property owner's property without prior written consent of the adjoining property owner(s) affected by such change and written approval by the Town Engineer. This includes changing exiting runoff from sheet flow to concentrated flow.
