SUBJECT: 6850 S Brosius Grading Plan- 2nd Engineering Review
TO: Rick Engineering Company ATTN: Dan Castro
LOCATION: T15S R14E Sec16, Ward 5
REVIEWERS: Jason Green, CFM
ACTIVITY: T08BU00855 (Grading Plan)

SUMMARY: Engineering Division of Development Services Department has received and reviewed the revised grading plan (T08BU00855), Drainage Report (Rick Engineering Company, 14FEB08 revised 01MAY08), Geotechnical Exploration Report (GEC, 08APR08 with Supplements No. 1 and 2) and Stormwater Pollution Prevention Plan (Rick Engineering Company, 28ARP08, revised 15AUG08) for the above referenced property. Engineering Division does not recommend approval of the grading plan application or Stormwater Pollution Prevention Plan (SWPPP) at this time. The Drainage Report was reviewed for grading plan purposes only. The following items need to be addressed:

GRADING PLAN COMMENTS:

1) Provide a copy of an approved site plan (T08CM00528). The grading plan can not be approved until verification that all details, locations, dimensions, and plan profiles match the approved site plan. Verify all information associated with the site plan is shown on the grading plan that will be used as the construction document. Per comment letter a copy of the approved site plan is included; however DSD Engineering has not yet approved the site plan. Once all comments are addressed on the site plan and it has been stamped by all DSD Departments include with the next grading plan submittal.

2) Restated: The following comments and redlines may not reflect all of the minimum engineering and Quality Control comments that must be addressed prior to resubmittal. Make sure that all drainage infrastructure, dimensions, details, sections, transitions, keynotes, and all other aspects of this project meet the minimum requirements within DS Sec.2-08, 3-01, 3-05, 6-01, 10-01, 10-02, and 11-01 and are reflected on the grading plan sheets. Due to the DSMR application and the redesign of the project there are new comments that were not on the first grading plan review.

3) DS Sec.2-02.2.1.A.16: Revise the grading plan to label and dimension all drainage infrastructure locations per the submitted Drainage Report. Specifically:

a) Complied.

b) Complied.

c) Revise Sheet 6 of the grading plan and the proposed 15-foot curb opening for the 15-foot access ramp into Basin 1P. The access ramp as proposed with 2-foot wedge curb and the 3-foot transitions is not recommended. Per Standard Detail 210 the transition from vertical to wedge curb is 10-feet. The grading plan shows a 3-foot transition which does not meet this requirement. For a redesign of the basin access ramp please contact Jason Green or Jim Femling, Inspection Supervisor for recommendations on how to construct the access ramp to meet maintenance and construction requirements. Removable bollards will be required at the access ramp to prevent unauthorized access into the basin.

d) Complied.

e) Complied.

f) Complied.

4) Complied.

5) DS Sec.6-01: Revise Details P and Q for the proposed refuse containers to correctly label and dimensions all requirements shown in Figure 3, DS Sec.6-01. Specifically the 1" diameter x 6" long galvanized anchor pipes that are to be flush with the concrete for the door support when opened and closed. These did not show up on the details at the 2nd submittal as shown on the 1st.

6) DS Sec.10-02.14.3.3: Revise the grading plan to clarify that the required maintenance access ramps that are proposed into all basins meet the maximum 15 percent slope. Revise the grading plan, Sheet 6, to clearly label the maximum 15 % slope for the access ramp into Basin 1P. This comment was not fully addressed with this resubmittal, revise.

7) Complied, DSMR 08-31.

8) Acknowledged and Complied

9) Complied, DSMR 08-31.

10) DS Sec.2-02.2.2.B: A) Revise the grading plan to show the temporary stormwater diversion channel/berm along the proposed phase line. Stormwater from Phase I can not drain over the undisturbed area of Phase II as shown on the grading plan. B) Provide an additional temporary construction barrier between Phase I and Phase II to prevent grading encroachment and storage of materials from Phase I. Show barrier in Detail EI and EII. This comment was not fully addressed with the 2nd submittal.

11) Complied.

12) Complied.

13) Restated: Approval from TDOT Permits and Codes for all improvements within the public right-of-way will be required. A right-of-way use permit application will be required prior to construction. Contact Thad Harvison, (520)-837-6592 or Thad.Harvison@tucsonaz.gov for all right-of-way requirements and permit applications.

14) Restated: Please ensure that any future grading plan will be consistent with the site plan, Drainage Report and Geotechnical Report. Grading standards may be accessed at: http://www.ci.tucson.az.us/dsd/DevStandsTOC.pdf

NEW COMMENTS ON 2nd Review Due To Redesign and DSMR:

15) Revise the grading plan to show a new detail or modified detail (N/9) for all basin access ramps. Basin access ramps must be constructed out of a drivable surface. Rock riprap as shown in the depressed curb detail N/9 will not work at the access ramps only the curb openings in the vehicular use area.

16) For future right-of-way work or a right-of-way use permit a revocable easement may be required by TDOT Permits and Codes in order to construct the handicap access ramps at the driveway entrances as shown. The handicap ramps are partially within the subject property and not fully within the right-of-way. Refer to Thad Harvison, (520)-837-6592 or Thad.Harvison@tucsonaz.gov for all right-of-way requirements and questions.

17) DS Sec.10-01.3.6.2: Revise the grading plan and Basins 1P and 4P to provide a security barrier around the basins. Security barriers must be provided at the top of all basin slopes steeper than 4:1 (H:V) where water depths exceed 2 feet. Basin 1P has vertical retaining walls with a water depth of 2.3 feet and Basin 4P has basin slopes of 3:1 (H:V) with a water depth of 2.40 feet.

18) Revise the detail reference for the proposed 13 cell sidewalk scupper on Sheet 5 of 6. The detail on sheet 5 references Detail X/9, however the correct detail is X/10, revise.

19) Revise plan view or provided a table with Detail N/9 for the proposed riprap pads at the curb openings and scupper locations. Per the detail the pad lengths and widths are to be called out "per plan"; however the dimensions are not shown in plan view or on the detail, revise.

20) Revise the grading plan to show riprap pad dimensions for all proposed pad locations, specifically for keynote #16 and the proposed 2 cell scupper location.

21) Revise plan view and/or Details Z/10 and AA/10 to call out the Standard Detail for Public Improvements for the proposed catch basins. If a Standard Detail is not proposed provided a modified detail in plan view to verify conformance with public standards.

GEOTECHNICAL REPORT:

22) Complied.

a) Complied.

b) Complied.

STORMWATER POLLUTION PREVENTION PLAN: The SWPPP does not meet the minimum requirements of the AzPDES Construction General Permit (CGP).

23) Per City of Tucson Code Ordinance 10209, Chapter 26 Section 26-42.2: "For land disturbing activities that fall under the jurisdiction of this Article, a Stormwater Pollution Prevention Plan must be prepared and certified by an engineer, or a landscape architect and submitted along with the application for a grading permit to the City of Tucson Development Services Department." The SWPPP report and exhibits must be signed and sealed by the engineer of record or by a Registered Landscape Architect, revise. Submitted exhibits are not signed and sealed by the engineering of record.

24) Part IV.C.3.e: Identify on the map locations of off-site material, waste, borrow areas, or equipment storage. Revise the SWPPP Exhibits to show temporary construction fencing at the Phase I and Phase II boundaries. Temporary construction fencing is required at the boundary locations to prevent grading encroachment and storage of materials and stockpiles on Phase II during the construction of Phase I.

25) Part IV.C.3.b: Identify on the map areas of soil disturbance. Identify on the map areas not to be disturbed. Revise the Phase Lines shown on the exhibits to correlate with the limits of disturbance. The phase lines shown are not correctly labeled for Phase I and Phase II.

26) Part IV.D.5: Describe structural practices used to divert flows from exposed soils (Phase I), store flows and limit runoff and the discharge of pollutants from exposed areas to degree attainable (Combination of sediment and erosion controls must be used). Provide a temporary berm or ditch at the phase line boundary to prevent runoff from Phase I into the undisturbed area of Phase II. Per the slopes shown on the grading plan and SWPPP Phase I drain into Phase II at the topography break.

27) Part IV.H.6: Describe how and where the inspection records will be maintained for at least three years. Revise Section 1.1, Page 2; Section 7.0, Page 24; and Section 8.0 Page 25 to include where the SWPPP will be retained for the 3-year period.

28) Part IV.J.1: The Operator must sign the SWPPP. Section 1.3, Page 2 is missing the signature of the Operator Mr. Michael Sajjadi, revise.
