ADDRESS/PARCEL: 447 S MAIN AV/117-14-147B
ZONING: HC-3, HO-3

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.
The comments provided are preliminary and are not to be assumed as a complete review of the proposal. During the Development Package review process, a full review will be made by Landscape/NPPO to assure compliance with the applicable UDC development criteria and Technical Standards.

COMMENTS:
1. There must be a NPPO or NPPO waiver. An NPPO is required per UDC 7.7.3-B. A Native Plant Preservation Plan, Section 7.7.4, is required to be submitted or approved or a request for an exception from the Native Plant Preservation requirements approved in accordance with Sections 7.7.3.D.3 & .4 of the UDC and Admin. Manual Section 2-11.0.0 prior to Grading Plan approval.
2. A landscape plan is required per 7.6.2.B.1-b. The Unified Development Code (UDC) requires all new development or an expansion of greater than 25% of an existing development to submit a landscape plan, UDC 7.6.2. Preparation of the landscape plan shall adhere to UDC 7.6.4 and Administrative Manual 2-10.
3. Ensure the required number of trees is in all vehicular parking areas (1 tree: 4 parking spaces) per UDC 7.6.4.B.1. Trees are to be distributed evenly throughout the parking area, UDC 7.6.4.1.B.1, UDC Technical Standards Manual 5-01-.3.2 and UDC 7.6.4.B.1.a.
4. There will need to be a street landscape border on S Main & W Simpson St per UDC 7.6.4.C-2 and Table 7.6.4-1. See UDC 7.6.4.C for landscape border requirements.
5. See Engineering notes for Retention/Detention.
6. All landscape plans shall incorporate water conserving design as defined in UDC Section 7.6.6, Use of Water, and as described in the Technical Standards Manual 5.01-5.11.
7. The Landscape Plan should match the Commercial Rainwater Harvesting Plan as well as the Grading Plan. Landscape plan should have spot elevations in the detention/retention areas as well as in all water harvesting areas in the Landscape Plan.
8. Maximize the rainwater harvesting across the site into the landscape areas, including but not limited to the street landscape borders as well as the tree wells for the required trees for the parking lot.
9. Commercial Rainwater Harvesting plan is required per UDC Technical Standards Manual – Section 4-01.3.0. and Section 5-01.0.0 Landscaping and Screening. Adherence to the Low Impact Development Standards outlined in Section 5 of the PCRFCD Design Standards for Stormwater Detention and Retention is required and shall work in conjunction with the Commercial Rainwater Harvesting design. Using Low Impact Development design and water harvesting provides critical basin detention and first flush retention for all new development and impervious area. The newly adopted Detention/Retention Manual can be found: https://webcms.pima.gov/UserFiles/Servers/Server_6/File/Government/Flood%20Control/Rules%20and%20Procedures/Stormwater%20Detention-Retention/dssdr-final-201406-manual.pdf

With CoT edits to the manual are found at: https://www.tucsonaz.gov/files/pdsd/codes/Detention_Retention_Manual_Tech_Standards_Amemdments.pdf
10. The Commercial Rainwater Harvesting Plan must utilize the Site Water Budget (located here: https://www.tucsonaz.gov/Departments/Planning-Development-Services/Building-Safety/Water-Energy-Conservation). See TSM 4-01.0.0 Exhibit A. The Site Water Budget is how the Water Dept tracks the irrigation water use on-site, not first flush retention volume charts.

Site Zoning REVIEW COMPLETED CDRC Thursday Pre-Submittal Transmittal
PDSD Zoning Review
FROM: Nathan Herrera, Planner
PROJECT: Thursday Pre-submittal meeting - TP-PRE-1223-00395
Address: 447 S Main Ave
Zoning: HC-3/HO-3
Existing Use: Parking
Proposed Use: Multifamily
TRANSMITTAL DATE: January 18, 2024

COMMENTS:

1. Development must comply with the Administrative Manual Section 2-06 - Development Package.

2. Residential-Multifamily is an allowed use in the HC-3 and HO-3 zones. Allowable density in the HO-3 zone is 22 units per acre. Allowable density in the HC-3 zone is 87 units per acre.

3. Parking is calculated as follows (Table 7.4.4-1 UDC); The number of spaces per dwelling unit is based on the number of bedrooms in each unit as follows:
• Studio, less than 400 sq. ft. GFA - 1.00 space per dwelling unit
• Studio, more than 400 sq. ft. GFA, and 1 Bedroom - 1.50 spaces per dwelling unit
• Two Bedrooms - 2.00 spaces per dwelling unit
• Three Bedrooms - 2.25 spaces per dwelling unit
• Four or More Bedrooms - 2.50 spaces per

b. Long-term .5 spaces per bedroom. Minimum 2 spaces required.

See UDC Article 7.4.9 for design specifics.

5. For nonresidential and multifamily development abutting an Arterial or Collector Street the minimum required street perimeter yard is ten feet, as measured from the existing or future property line as determined by the adopted Major Streets and Routes Plan, whichever is greater.

6. For nonresidential and multifamily development abutting a Local Street: the minimum required street perimeter yard is 20 feet, as measured from the street property line (6.4.5.)


7. The maximum building height for a commercial use in the HO-3 zone is 40’ (6.3-3.A UDC).

9. Ensure access standards found in section 7.8 of the UDC and sections 7-01.0.0 and 10-01.0.0 of the Technical Standards Manual are met.

10. The site is located in a Historic Preservation Zone. Some requirements found in UDC Article 5.8 may be applicable to this project. Reach out to Jodie Brown at Jodie.Brown@tucsonaz.gov for further information on development within a historic zone.

11. It appears that there is shared parking access with the property directly to the east. A cross access agreement will need to be recorded, if one does not exist.

12. The comments provided are preliminary and are not to be assumed as a complete review of the proposal. During the Development Package review process, a full review will be made by Zoning to assure compliance with the applicable UDC development criteria and Technical Standards.

TW New Area Development REVIEW COMPLETED TP-PRE-1223-00395 - Pre-Application Conference Review v1 – 447 S MAIN AV

Tucson Water has no objections to the proposed development and offers the following comments for your convenience:

1. This project will need to obtain the bulk of its water from the existing 8” cast iron pipe constructed Simpson Street in 1907 under Plan No. FN 1272, and rehabilitated in 1998 under Plan No. 1-002-003-98. A secondary connection may be made to the existing 6” PVC water main constructed on the west side of Main Avenue in 1990 under Plan No. PN 146-1990, if necessary.

2. The required water meter size for this project will be determined by a water fixture count conducted in accordance with the 2018 International Plumbing Code and Tucson Water’s Water Meter Sizing Guidelines. Tucson Water’s Water Meter Sizing Guidelines are available at https://www.tucsonaz.gov/files/sharedassets/public/v/1/city-services/tucson-water/documents/signed_meter_sizing_guidelines_march_2020.pdf

3. If a 3” or larger water meter is needed for this development, the water meter will need to be located within a large meter enclosure that is a minimum of 25’ long x 10’ wide x 5’ high per Tucson Water Standard Detail SD-314. The entire large meter enclosure must be located on the property in a water easement granted to the City of Tucson.

4. The estimated water pressure in this area at ground level, based on elevation, is in the 52-59 psi range. A private on-site pressure booster station may be necessary to serve the upper floors of this development.

5. An existing 36” reclaimed water transmission main constructed in 1990 per Plan No. 146-1990 lies on the east side of Main Avenue. This reclaimed water main will need to be protected during the excavation for, and construction of, the underground parking.

6. The water mains in this area are shown on Tucson Water’s NW131413 valve map. Copies of the valve map(s) and ‘as-built’ plans referenced in these comments may be obtained from Tucson Water’s Mapping & GIS Center by sending an e-mail request for them to TWMapInfo@tucsonaz.gov.

The above comments are based on the limited preliminary information provided by the applicant and should not be construed as a complete review of the proposal. Any questions, comments or concerns about these comments may be directed to:
