1. An unvented roof assembly requires an air-impermeable rigid insulation material with a minimum R-5 value applied correctly to either side of the roof sheathing, R806.5. Show a roof design with insulation types and minimum thickness for meeting the condensation control requirement and the minimum total insulation value of R-38.

PLUMBING PLANS:

1. A single story dwelling with the clothes washer at an interior wall requires only one gray water fixture preparation with under floor gray drainage plumbing, Ordinance #11089. Provide a bathing fixture 2” drain looped 3’ beyond an exterior wall below grade before connection to the building drain. Update the size to 2”.

04/27/2020 ANDREW CONNOR NPPO REVIEW Reqs Change Add the following notes to cover sheet:

Vegetation Retention and Revegetation
a. Vegetation Retention
(1) Existing viable and transplantable trees with four inch or greater trunk diameter and cacti shall be preserved in their original locations, except for building sites and access and utilities serving building sites.
(2) When retention of the above trees and cacti in their original locations is not possible due to building site location, the trees and cacti shall be salvaged and replanted in areas requiring revegetation, whenever possible.
b. Revegetation
All cut or fill slopes that are no steeper than three horizontal to one vertical and all utility trenches or septic leaching fields that are not located in parking or driveway areas shall be revegetated in compliance with the following standards:
(1) All plants used in revegetation shall be the same as the native vegetation on the site prior to grading or clearing or any adjacent site; and,
(2) Revegetation shall be accomplished with the following minimum standards for plants:
(a) Desert trees, a minimum of 15-gallon size with a minimum trunk diameter of two inches measured at the soil level, or large specimen cactus shall be placed at the same vegetation density found on the site prior to any clearing, grubbing, or grading; and,
(b) Seeds for trees, desert shrubs, and grasses shall be planted with a density adequate to control erosion and may use one of the following methods of planting: Raked into the soil with appropriate mulch materials; hydroseeding; anchored mulches; or established on jute, rolled straw, or similar material. Another method may be approved by PDSD.
(3) A temporary watering system shall be installed until the revegetation materials are established.
3. Slope Stabilization
All slopes steeper than a ratio of three horizontal to one vertical, with the exception of retaining walls, shall be stabilized with properly engineered stone riprapping or sculptured rock as follows:
a. Stone riprapping shall be hand-placed on the slope;
b. The stabilizing material used shall blend with the natural appearance of the site or lot and the surrounding terrain; and,
c. Vegetation retention and revegetation should be used in conjunction with riprapping.
