| 04/28/2009 | ANDREW CONNOR | NPPO | REVIEW | Denied | Add the following notes to site plan (Including heading): CITY OF TUCSON DEVELOPMENT STANDARD NO. 9-04.0 HILLSIDE DEVELOPMENT SITE IMPROVEMENT Add the following notes to site plan (Including heading): A. Vegetation Retention. 1. Existing trees with four (4) inch or greater trunk diameter and cacti will 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 will be salvaged and replanted in areas requiring re-vegetation, whenever possible. B. Re-vegetation. All cut or fill slopes, which are no steeper than three (3:1) and all utility trenches or septic leaching fields which are not located in parking or driveway areas will be re-vegetated in compliance with the following requirements. 1. All plants used in re-vegetation must be the same as the native vegetation on the site or any adjacent site prior to grading or clearing. 2. Re-vegetation will be accomplished with the following minimum requirements for plants. a. Native trees, a minimum of fifteen (15) gallon size with a minimum trunk diameter of two (2) inches measured at the soil level, or large specimen cactus will be placed at the same vegetation density found on the site prior to any clearing, grubbing, or grading. b. Seeds for trees, desert shrubs, and grasses will be planted with a density adequate to control erosion and may use one of the following methods of planting or any other method approved by the Zoning Review Section at DSD. 1) Raked into the soil with appropriate mulch materials; 2) Hydro-seeding; 3) Anchored mulches; or 4) Established on jute, rolled straw, or similar material. C. A temporary watering system must be installed until the re-vegetation materials are established. D. NPPO pre permit inspection is required prior to grading inspection can be scheduled by calling IVR system and entering inspection code 09015 or calling Landscape Field Representative directly @ 520- 837-4950 Fencing shall be required during construction per DS 2-06.8.0 Fig.1 for all undisturbed natural desert areas E. Grubbing, grading, and clearing are to occur only within the areas identified on the grading plan and staked on the site or lot. The limits should include all cut and fill areas, leach fields, septic tanks and future development areas. |
| 05/07/2009 | ELIZABETH EBERBACH | ENGINEERING | REVIEW | Denied | TO: Timothy Robertson, RA SUBJECT: 977 S Bill Martin Dr Site/Grading Plan Review LOCATION: Canyon View at Starr Pass lot 28 REVIEWER: Elizabeth Leibold PE ACTIVITY NUMBERS: T09CM00922 / T09BU00580 Summary: Engineering Division has reviewed the submitted plan review package including a copy of the site plan. Engineering does not recommend approval until the following comments are addressed. SITE / GRADING PLAN COMMENTS: 1) DS Sec 9-04.3: Show compliance for this section of the HDZ standards. Address the following comments: a) DS Sec 9-04.2.1.G: The proposed lot disturbance area is not acceptable based on Hillside Development Zone average cross slope (ACS is estimated over 30%). The Tentative and Final Plats have general notes restricting the allowable area based on HDZ requirements. Provide calculations for the Average Cross Slope (ACS) per LUC 2.8.1.6 to justify proposed grading limits. Also, please provide a copy of Board of Adjustment case for the subdivision which may provide further information regarding maximum developable area. Contact Russlyn Wells at 837-4948. Otherwise, a variance process may be needed for proposed disturbance area exceeding maximum gradable area per section LUC 2.8.1.6.A. b) Provide the following HDZ data on the plan: i) Total lot area in square feet per Final Plat. ii) LUC Sec. 2.8.1.6.A: Average Cross Slope (ACS) percentage for entire lot area. Or, provide the ACS percentage for area of lot that excludes any set-aside natural area. This may be area of protected peak or additional area including steep slopes that will not be used for further development on the lot in the future. iii) Total Allowable Grading Area in square feet, based on LUC Table 2.8.1.I. iv) Square footage of disturbance area that reflects the revised, actual proposed total disturbance / graded area. c) Label on planview any areas within the lot for proposed Natural Undisturbed Area. 2) Provide a geotechnical report that provides recommendation for project. Specifically address the following comments based on compliance with geotechnical recommendations: a) Label slope grades in cut area and at driveway or revise grading design to show compliance with geotechnical report. If geotechnical inspections during construction are required, provide note on grading plan. b) Per IBC, 10-ft at 5% earthen grade is required at minimum around foundations, unless the geotechnical addenda supports other design. The rear slope appears to be less than 10-feet from structure. Clarify with details and on planview to provide positive drainage from structure and sufficient setback at retaining systems. 3) DS Sec.11-01.4.C: Provide the following clarification/notations that will be required to be shown on a grading plan: a) It is recommended that the plans be labeled as Site/Grading Plan. Otherwise submit a separate sheet for the grading plan. a) Provide benchmark elevation for project and show on planview. Basis of elevation shall be from an established entity near or on the lot. b) DS Sec. 11-01.10.5: Clarify proposed slopes at southeast and south and east side yard areas and show with details how stormwater runoff flow is intercepted and label erosion protection. Provide details or sections. Capacity for interceptors shall have a minimum of 30-in wide and 12-in deep. c) For retaining systems, label more top & toe of wall elevations on the plan. d) For toe and top of slopes, provide proposed spot elevations on planview. e) Label manhole adjacent to lot. f) Label utility line trenches from street to house. Include trenches within disturbance limits. g) DS Sec.2-02.2.11: Address the following driveway comments: i) Label elevation at driveway entrance at street. ii) Label width of driveway. iii) Label driveway slope grade for access from street. iv) DS Sec.2-02.2.1.A.19: Label the edge of existing pavement for Bill Martin Drive. v) Provide cross section from driveway to street across side slope with proposed slope grades. Clarify cut/fill condition and provide spot elevations at west edge of driveway. vi) Label and show erosion protection along edge of driveway and at corners of retaining wall edges. h) DS Sec.11-01.10.5: South yard at base of cut slope need clarification. Address the following comments: i) Provide spot elevations in rear yard and within interceptor swale(s) directing runoff away from proposed house and around the yard. Provide spot elevations in rear yard indicating/clarifying positive flow out of the rear yard. Show how design will prevent stormwater runoff into or ponding in the west, south and east yard areas. ii) Interceptor swales are required at top of cut slopes. Capacity for interceptors shall have a minimum of 30-in wide and 12-in deep. Show detail for rear yard interceptor swale and depict on planview. i) DS Sec.9-04.3.1.A.2, Land Use Code (LUC) Sec. 2.8.1-I: Assure sufficient grading area is provided for grading construction of lot 28. Revise grading limits to provide sufficient area for wall construction and slope runout grading disturbance, interceptor swales, construction staging area, and include driveway and utility line trenching within grading limits / disturbed area. Also, label locations within the driveway or yard areas for construction staging areas, construction materials, and vehicle parking. 4) Add general grading notes to the Site/Grading Plan. Address the following general grading note comments: a) Revise letter size (12 pt min) for general notes for legibility. b) Add a general note stating that there shall be no disturbance, and that materials and / or construction equipment may not be stockpiled or parked, outside of approved grading limits at any time. c) Add a Grading Note to state that all grading construction work shall conform to IBC Chapter 18, City of Tucson DS Sec.11-01, and Hillside Development Zone requirements DS Sec.9-04.3. d) Add note that all rip rapped slopes shall have handplaced stone with filter fabric per HDZ requirements DS Sec.9-04.3.3.A unless required to have handplaced rip rap or other slope protection as per geotechnical engineering report or addenda. e) Add note stating that the Grading Permit, Geotechnical Engineering Report, as well as the copy of the Grading Plan, shall be kept at the site at all times, until Final Grading approval. f) Add note that project shall conform to any geotechnical engineering report and addenda for this site.
