| 12/04/2025 | Site Engineering Standard | REQUIRES RESUBMIT | Permit: TD-DEV-0525-00143 Location: 6444 S FONTANA AV Review Date: 12/4/2025 This plan has been reviewed for compliance with applicable development criteria in the City of Tucson Unified Development Code (UDC) Administrative Manual (AM) Section 2-6 and Technical Manual (TM) Section for waste management, Pedestrian Access, Hydrology -Retention/Detention Requirements, and all site standard code. Drainage Manual Link: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/engineering-code/cot-drainage-manual-searchable.pdf Design standards for Stormwater Detention and Retention Link: https://www.tucsonaz.gov/files/sharedassets/public/v/1/pdsd/documents/engineering-code/updated-retention-detention-manual.pdf Site Engineering Comments: 1. Previous comment regarding Trash handling and waste not fully addressed. It is required that all developments to include provisions for waste storage and collection. Environmental Service (ES) have no approved the removal of the requirement which means it will remain required. At minimum the development should include provisions for a single enclosure to support for this potential need. Refer to Technical Standards Manual 8-01.0 for reference and technical requirements. Contact Andy Vera at Andy.Vera@tucsonaz.gov to receive official approval and provide approval documentation in the resubmission. Remove the Waste management section from the drainage report as well as it is not necessary to be within said document. 2. Revise planning note 4 as it appears to be miscalculated. 3. Provide the general note “The developer, any successors and assigns, will hold the City of Tucson, its officers, employees, and agents harmless from any and all claims for damages related to the use of this development as shown hereon, now and in the future, by reason of flooding, flowage, erosion, or damage caused by water, whether surface flood or rainfall.” Administrative Manual 2-06.4.7.B.1 4. Provide the general note “Drainage will remain in its natural state and will not be altered, disturbed, or obstructed other than as shown on this site plan.” AM 2-06.4.7.B.3 5. Provide the general note “No structure or vegetation shall be located or maintained so as to interfere with the sight visibility triangles in accordance with Section 10-01.5.0, Sight Visibility, of the Technical Standards Manual.” AM 2-06.4.7.C.2 6. Revise the page number and total number of pages within the DP (i.e., sheet xx of xx) AD 2-06.4.2. D the development package is 12 pages, but it appears the landscaping plans are not included in the total. 7. Revise the drainage report to show the City of Tucson hydrologic data sheets for each principle point of drainage concentration. These should include both pre-development and post-development conditions. They should be placed in an appendix and summarized in the report. Include all “City of Tucson Hydrologic Data sheets for computing the 100-year Peak discharge” This form can be found within the Drainage manual Page 4.09 8. City of Tucson flood peak estimating method (Flood Peak Estimator Procedure) is required to be used for when development occurs within the city limits. Drainage report states the NRCS method which will not be accepted as an approved method of analysis. A Step-by-step guide and requirements can be found within the City of Tucson Drainage Manual. This considers the 100-year 1-hour rainfall depth of around ~3inches used for calculating the Peak discharge rates. 9. The DSSDR states “Filter materials remove pollutants and are required for pervious pavement systems. A granular filter without a geotextile is required, unless an alternate design is approved by the Floodplain Administrator. A 6-inch-thick filter layer consisting of materials conforming to the gradation presented in Table 5.1 below shall be installed as the bottom layer of pervious pavement systems.” DSSDR 5.9.5.6 This has not been addressed – the geotextile fabric would not suffice for this condition. 10. Provide a retention/detention basin maintenance checklist and schedule in the Drainage report. The small section is insufficient in addressing a detailed checklist 11. The drainage report states infiltration testing every 5 years, but this appears unrealistic in catching short term issues with infiltration, especially because a Geotech report with infiltration testing has not been provided as required by the DSSDR 5.9.5.3 12. The leveling course shall consist of American Association of State Highway and Transportation Officials (AASHTO) #8 aggregate or approved equal for the pervious concrete. DSSDR 5.9.5.4 13. It should be made known at this phase of review that overall, it is unrealistic and not practical regarding the proposed use of the “recycled concrete” for the entire means of achieving/satisfying the City of Tucson’s First flush retention and balanced basin detention drainage requirements. The life cycle of the concrete will consist of being compacted over-time by all the vehicles that enter/exit the site with more than likely requiring consistent regrading/uncompacting being required for up-keep. Functionality wise, everything presented thus far has not fully argued and shown that the concrete will function as intended. When pervious surfaces/pavements are proposed/accepted, they are done so supplementary to sites core drainage infrastructure, which is why they are recommended as a Low Impact Development design option/method to help achieve a portion of drainage requirements. The City of Tucson will not be accepting/approving of the proposed use of the recycled concreate as a means to meet required drainage requirements and this is because of the complexity of the process posed to achieve the desired outcomes such as ensuring proper compaction, maintaining ADA surface requirements, and necessary continuous monitoring/inspecting while also considering the complexity of the proposed perpetual maintenance of said concrete involving many key factors which may inevitably be underkept which could potentially result in harm due to lack of built in-place drainage infrastructure. Due to the nature of type C soils being present throughout the site, making retention less achievable, it would be allowable for the City to waive retention requirements and solely require detention.
