PLAN REVIEW COMMENTS

Plan review for the above referenced structure has been completed. This letter reflects comments to be addressed. For facilitating a shorter back check time, please provide updated plans and calculations with a written response to each of the notated items indicating action taken. Do not cloud the changes made for comment updates; revisions are processed if changes occur after the permit is issued.

SCOPE OF REVIEW: The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2018 International Residential Code and 2018 International Energy Conservation Code. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions, and concerns before permit approval.

GENERAL REQUIREMENTS: The City of Tucson adopted the 2018 IRC with amendments and building ordinances for all dwellings. Provide a response letter addressing each comment with location of change on the plans. Submit separate letter and plan set files.

GENERAL COMMENTS:

1. A special inspection request is required with the updated plans for the post-tensioned slab, R109.2.

2. Provide a registered Arizona structural engineer seal on the plans, R401. Include sheet S1.3.

SECTIONS - DETAILS:

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. Clarify the ceiling/roof insulation detail showing the air-impermeable rigid insulation material adhered to either side of the roof sheathing along with the batt insulation. Update keynote #6 at section #6, sheet A4.1 and details on sheet S4.0.

PLUMBING PLANS:

1. The Tucson Water Department limits flow rates for each water meter size in compliance with P2903.7. Show an appropriate water meter size.

MECHANICAL PLANS:

1. Provide (an HVAC system with fresh air intake) whole-house mechanical ventilation with controlled exhaust, R303.4; N1103.6 & M1505.4. Identify the device model number providing an adjustable setting and note the minimum continuous setting. A four- or five-bedroom dwelling greater than 4500 SF requires a total of 105 CFM continuous setting.

INTERNATIONAL ENERGY CONSERVATION CODE:

1. Energy Certificate: (Mandatory) place near the indoor furnace or in utility room, N1101.14. Add notation to plans.

SITE LANDSCAPE/NATIVE PLANT PRESERVATION SECTION

PROJECT: SFR
ACTIVITY NO: TC-RES-1224-07443
ADDRESS: 3774 W TOHONO CROSSING PL
ZONING: R-1 RESIDENCE ZONE; HILLSIDE DEVELOPMENT ZONE, ERZ

This plan has been reviewed for compliance with applicable development criteria in the City of Tucson Unified Development Code (UDC) Administrative Manual (AM) Section 2-11 and Technical Manual (TM) Section for landscape, native plants, and water harvesting.

Please resubmit revised drawings along with a detailed response letter, which states how all of the Site Landscape/NPPO Section review comments have been addressed.

SITE LANDSCAPE/NPPO SECTION COMMENTS:

1. There are many Ocotillos located within the grading limits of the site that appear to be scheduled for removal. Ocotillo are protected native plants. Add the Ocotillo to the inventory and provide transplant and mitigation calculations. If there is a master development plan for Starr Pass that gives exception to some of the NPPO plants, then provide that Development Package case number to this set of plans.

2. Add the following notes to the site plan for Hillside Development Revegetation standards:

HILLSIDE DEVELOPMENT ZONE (HDZ) SEE UDC 5.2, ADD THE FOLLOWING NOTES TO THE 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.
