| 04/15/2026 | Floodplain Administration Review Standard | REQUIRES RESUBMIT | City of Tucson Floodplain Administration has received the first submittal of the grading plan for this project since the CLOMR was submitted to FEMA and provides the following comments. A site plan, development plan or tentative plat was missing from this submittal. This review includes: Preliminary Grading Plan, Casitas at La Mariposa Stormwater Pollution Prevention Plan, CEC Preliminary Drainage Report, CEC Environmental Resource Report, and Pattison Engineering Soils Report. 1) Technical Standard (TS) Sec 4-04.2.2: Address the following Drainage Report comments: a. The proposed Recharge Basin is located at the confluence of two ERZ watercourses - the Aqua Caliente Wash and Tanque Verde Creek, within the FEMA High Risk Floodway and SFHA Zone AE with regulatory flood depths of 2-4 feet deep. This location is expected to have varying flow hydraulics during the regulatory storms impacting the basin which is proposed to be used as a borrow pit for the fill material for the Casitas at La Mariposa. b. TC Sec 26-6: A floodplain use permit shall be required for extraction of sand, gravel and other earth products within a floodway or floodplain (which includes the floodway fringe areas) or erosion hazard areas. An engineering study outlining effects on stream mechanics prepared by a state - registered professional civil engineer shall be required with an application for a floodplain use permit for major extraction operations, for operations in locations that appear to be hazardous because of their relative proximity to structures or banks of watercourses, and for any other operations considered by the city engineer to be potentially hazardous. Any extraction of sand and gravel or related materials in the floodway, floodway fringe or erosion hazard areas shall be allowed only if a reclamation plan is also provided for the extraction operation. Reclamation plan shall show that all adverse effects of extraction are mitigated, and shall also contain a timetable and financial assurances for accomplishing reclamation. City engineer may require bonds or other financial assurances appropriate for the sand and gravel extraction operation. Operations plan and any engineering study required shall meet approval of the city engineer. c. The engineering study is for the purpose of evaluating the possible flood and erosion related hazards and must include considerations of effects of the excavation on water velocities, direction of flows, volume of flows, channel geometry (shape and size), type of channel banks, depth of flow, and other items that may be pertinent to stream mechanics, which includes an analysis indicating a balanced sediment flow system or channel aggradation, and resultant effects on structures (including but not limited to roads, bridges, culverts and utilities), banks of watercourses, adjoining lands, and groundwater recharge for the respective alluvial watercourse. d. Excavation within a Floodway is typically not allowed as its primary use is for safe conveyance of floodwaters. Compliance to all subsections of TC Sec. 26-5.1 shall be itemized and explained in report. If compliance with all subsections is not achievable, the design should exclude the floodway areas. e. No online detention basins shall be allowed if any portion of the upstream wash is natural or if the watershed is greater than 100-acres without authorization. Since the proposed basin is proposed to receive floodwaters from the Agua Caliente watershed and is expected to need frequent sediment removal and basin side slope repairs, the City of Tucson will only grant approval if the Pima County Regional Flood Control District provides recorded documentation for the basin maintenance by the county. f. Section IV of report shall comply with soil engineering recommendations. g. Add TSMS Code and Watershed / Basin Management Area for project to report and explain impact to design of development. h. Add information about locations for the basin overflow/outlet spillway designs for basin and assure that the design is armoured for online flood conditions as the basin is located at the confluence of two major watercourses and within erosion hazard of this floodplain. i. Provide basin maintenance guidelines in appendix of drainage report. 2) TS Sec 4-02.2.5.B.1.a-x: Address the following ERZ-ERR Report comments: a. The ERR report is for both ERR and ERZ compliance with riparian floodplain requirements. Label the Report “Basin at La Mariposa ERZ-ERR” Report or similar. b. Add verbiage to either introduction or conclusion that states whether the project complies with City of Tucson UDC ERZ Overlay Code and riparian floodplain requirements. c. Please see this section of standards and provide paragraphs within the CEC Environmental Resource Report and in Table of Contents using lettering as outlined in the standards. d. ERZ floodplain encroachment that may be allowed is limited to road/access, utilities, or trails. Add explanation and show on exhibits within the report whether and how the Basin at La Mariposa project is proposed as a stormwater utility located within the floodplain limits of the confluence of the Agua Caliente and Tanque Verde Watercourses. e. TS Sec 4-02.2.5.B.3: Provide Mitigation Plan in ERZ-ERR Report per DTM Landscape Architect for riparian floodplain disturbance located at confluence of the major watercourses for the proposed Basin at La Mariposa project. 3) Tech Stnd Sec 2-01. For Grading Plan review, address the following comments: a. Clarify location of basin construction site entrance and access route between sites and associated grading for the access around the proposed basin site. b. The City of Tucson floodplain management cannot approve a stockpile grading permit within the floodplain without an approved site or development plan (which shall show stockpiling in non-floodprone areas other than CLOMR approved areas). Provide site plan or development plan for proposed basin development design. c. Label on grading plan (and to be submitted development plan) the watercourses that are subject to ERZ Overlay code. d. On grading plan (and to-be-submitted development plan), label centerlines of watercourses that are regulatory (local) floodplain that are not designated as ERZ Overlay Code washes. e. As previously discussed, both State and Federal compliance is needed for the proposed dredging in the floodplain. ADWR will be contacted by City of Tucson Floodplain Administration once a site plan or development plan is provided along with the grading plan. Excavation within a Floodway is typically not allowed. The City of Tucson Floodplain Ordinance does not exempt those sand and gravel operations which will divert, retard or obstruct the flow of waters in any watercourse from complying with and acquiring authorization from the city engineer pursuant to regulations adopted by the floodplain board under this chapter (floodplain ordinance). f. Tucson Code (TC) Sec 26-3.1(b)(2): Provide documentation for authorization, compliance documentation, or permitting from other agencies: i. The Nationwide Permit 29 referenced in report does not apply. If deemed required by Pima County Regional Flood Control District, acting on behalf of USACE, obtain 404 ASACE compliance and provide a sealed 404 statement page in report explaining 404 compliance for the dredging and filling activities. Also, provide letter from PCRFCD for USACE compliance. g. UDC Sec 5.7.5.B: Show on grading plan the required temporary grading construction fencing along the grading limits adjacent to the ERZ designated watercourse. h. Add note to development plan regarding TS Sec 4-04.14.3.2. i. Label and provide grading design, cross sections and details for onsite detention basins, including setback outlet armoured spillway design(s). j. If depth of basin or side slope grade warrant security barrier, show 42-in minimum height security barriers (vegetative or structural) for top of excavation area / detention basin. Provide calculations for wall opening sizing showing how 100-year flood conditions are conveyed under / through wall openings if wall is proposed. 4) Address the following related to 402 compliance – Grading Plan SWPPP: a. Update SWPP plans and SWPP report to reflect effective ADEQ Construction General Permit: “AZG2025-001 CGP”. The 2026 CGP is expected to be effective in August so consider using the effective CGP at time of grading permit issuance. b. Clarify, label and show temporary construction entrances and access locations for grading activity. c. Revise SWPP Report and plan to reflect a grading design for the development plan for Basin at La Mariposa. d. Show construction / maintenance / erosion hazard setbacks from ERZ regulatory floodplain along Agua Caliente Wash. e. Provide missing section details called out on planview. Include dimensions per development plan design. 5) TS Sec 4-04.2.2.1: Provide explanation or show on development plan regarding approved Rezoning conditions compliance. Please contact Elizabeth Eberbach at Elizabeth.Eberbach@tucsonaz.gov (520-429-4905) in DTM Engineering Division if you have questions. |

This review is contingent on submission of a parcel reconfiguration that matches the parcel boundaries as configured on this plan-set. a. Full review and approval for this permit cannot be granted until approved grading development package for fill site locations (parcels 133033960, 133033970, 133033980, 133033990, 133034000, 133034010, and 13303304C per General Note 2) is approved. 2. As this parcel/site is entirely within FEMA floodplain and floodway zones, it will be required that a floodplain use (FPU) permit be submitted for the work within a floodplain. This is an entirely separate permit that can be submitted for within the sub-records of this development package permit. For the FPU permit submission, please provide the plan set as well as the corresponding drainage report. 3. Provide the development package case number, TD-DEV-0126-00021, adjacent to the title block on all sheets. 4. Previous comment #3 not fully addressed. Demonstrate how all 14 standards are being met from COT code sec 26-5.1 Floodway development. Especially numbers 4, 5, 6, 10, and 13. Floodway has a no rise requirement which triggers encroachment analysis and pre- and post-flood conditions assessment for depth, velocity, and floodplain limits. If the floodplain limits increase - especially in a way that increases floodplain on a property, then the LOMR also needed to be submitted to City and FEMA. Please note, COT will need additional approvals from other agencies including Army Corps of Engineers for excavating in the FEMA high-risk floodway. 5. Upon completion of construction of the recharge basin, an As-built Certification shall be prepared by an Arizona registrant and submitted to the Floodplain Administrator and entity responsible for basin maintenance. The plan associated with the As-built Certification shall be used by the responsible party when performing periodic inspections and when restoring the basin to design specifications, if required. The Floodplain Administrator may utilize the certification during enforcement actions a. Provide the following Permitting Note to disclose this requirement: “Prior to issuance of any building permits an As-Built Certification (Plan) of the drainage and grading improvements that are required to mitigate off-site adverse impacts to the project shall be prepared. 6. An inspection and maintenance protocol including frequency of inspection, a checklist of items to be inspected and recommended maintenance when an inspection identifies a maintenance requirement shall be prepared by an Arizona registrant. The protocol may be included in the project drainage report or prepared as a separate document. The protocol shall be reviewed and approved by the Floodplain Administrator prior to approval of the tentative plat or development plan. The protocol shall be delivered to the entity responsible for inspection and maintenance. An example of a detention basin inspection and maintenance checklist is provided in Appendix F. DSSDR 4.1.1 7. Basins shall have a minimum of 1 sediment level measurement device, which can be incorporated into the weir or the side slope, or constructed as a separate stand-alone device. The device(s) shall be located where sediment is likely to accumulate. DSSDR 4.4.1.4. Provide a call-out/keynote for the location of the sediment level staking. 8. Provide a descriptor box adjacent to the proposed recharge basin on the grading plan Include a leader arrow to the basin or provide a label for the basin and reference the label on the top of the descriptor box. This can be done through an additional detail sheet or included on current basin detail sheet if the grading plans appear too narrow for such details. Include the following applicable information in the descriptor box: a. Total volume, cubic feet or acre feet; b. detention volume, cubic feet or acre feet; c. retention volume, cubic feet; d. d. first-flush retention volume, cubic feet; e. Q100 in, cubic feet per second; f. Q100 out, cubic feet per second; g. Basin top elevation, feet; h. 100-year water surface elevation, feet; i. 100-year ponding depth, (measured from the lowest elevation of the basin), feet. DSSDR 11.1.3. 9. A minimum of one 15-foot-wide vehicular access ramp shall be provided into the basin. The maximum roadway or access ramp slope shall not exceed 15 percent. Alternate means of access will be reviewed by the City Engineer on a case-by-case basis. Drainage Manual 14.3.4 10. The plans call out dumped rock riprap, ensure to include the required filter fabric as required by DSSDR 4.7.1 11. As this project is proposed between two major water courses, it will be required that an erosion hazard setback be calculated and delineated on the plan set as well as included within the drainage report. 12. As the site is subject to Environmental Resource Zone Standards, provide a call out/keynote to show the required temporary fencing. UDC 5.7.4.E 13. It is required that all regulated areas and protected riparian areas on the property be identified and delineated on the plan set. TSM 4-02.2.4 14. The drainage report is strictly preliminary and lacks encroachment analysis, hydraulic affect regarding the major water courses, or associated erosion hazard analysis. Revise accordingly to provide a full drainage/hydrology report to review how this recharge basin will truly function as intended. 15. As this project is associated with the “Casitas At La Mariposa” development, but entirely different sites and scopes, it is required that a drainage report be provided that solely covers the development, encroachment analysis, erosion hazard calculations, and floodplain impacts for the “Recharge Basin” project. 16. Provide water surface elevation contours relating to the associated floodplain and water course delineations on the grading plan. 17. Delineate the limits of recognized “FLOODWAY” on the grading plan. FOR PERMIT RESUBMISSION, IT IS REQUIRED THAT: Corrected/Revised Plan set and a detailed response letter document that clearly shows how you addressed all of Site Engineering’s and other reviewers’ comments for the completed review cycle. If you have any questions or concerns, please contact Marco Contreras at Marco.contreras@tucsonaz.gov |
