Comments:

1. The grading plan has been reviewed by Zoning Review Section but cannot approve the plan until it has been approved by the Engineering, and Landscape Review Sections and until all zoning comments or concerns have been addressed.

2. Zoning could not verify that the grading plan was in compliance with the approved site plan. Please submit two copies of the approved and stamped site, landscape, and NPPO plans with the next grading plan submittal.

3. Zoning will re-review the grading plan on the next submittal to insure compliance with the approved and stamped site plan. Additional comments may be forthcoming.

SUMMARY: Engineering Division of Development Services Department reviewed the Site Plan submittal and does not recommend approval at this time. The Drainage Report was reviewed for Site Plan purposes only. Address the following comments for resubmittal.

DRAINAGE REPORT COMMENTS:
1) In Section iii, the imperviousness is stated as 15%. The existing imperviousness needs to be based on existing houses or other impervious structures at the site, which may include existing concrete slab, and storage sheds. It may not include stockpiling of construction materials or other temporary impervious structures.
i) Provide justification of 15% impervious figure based on existing conditions, or revise statement on page 10.
ii) Update the affected existing conditions hydrologic data sheets.
2) Revise threshold retention volume calculations to reflect Table 4.3 runoff coefficients. Clarify reference to "Table 3.1".
3) DS Sec.2-03.2.3.J: Drainage Report shall provide details and calculations for a sediment trap or other sediment control device for basins.
4) DS Sec.10-01: Design for basins needs clarification. Explain outlet structure wall in report. This feature does not meet the natural look for basin designs. Provide solution for outlet that follows the guidelines listed in the Detention/Retention Manual.
5) Clarify scupper calculation sheet. Explain depths of scupper with a detail.
6) The soils in this area are D soils. Discuss impact to basin design for this project.

SITE AND GRADING PLAN COMMENTS:
7) DS Sec.10-01: Design for basins needs clarification. Address the following comments on sheet C2.2:
a) Provide existing and proposed spot elevations around perimeter of basin areas.
b) Show minimum 1% flow grade at bottom of basin areas to show positive drainage toward outlet bleed pipe and to reduce potential for ponding problems.
8) DS Sec.2-02: Explain/provide full parcel boundary information of sheet C1.1.
9) Add building numbers to sheet C2.2.
10) DS Sec.2-02.2.1.A.15: Show limits of the 100-year floodplain and water surface elevation on C2.2.
11) Show roof drainage directions on sheet C2.2.
12) Sidewalk shall be provided along west entrance area. Show on sheets C1.1, C1.3, and C2.2.
13) Show all size and locations for scuppers on sheet C2.2, including at drainage inlet adjacent to southwest building.
14) DS Sec.10-01.III.3.5.1.3.a, 10-02.14.2.6: A Geotechnical Evaluation was submitted for review. Address the following comments:
a) Provide any recommendation for setbacks from building to basins.
b) The soils report shall provide identification / assessment of any potentially hazardous geotechnical areas, and specifically, state whether there are special provisions for the soil preparation for this development in the area that was used for fire training. Provide any geotechnical recommendations.
c) Provide slope stability recommendations for any proposed constructed slopes.
d) Provide minimum distance from foundations to drainage swales
15) Revise street/parking/drive area sections to reflect page 8 of the Geotechnical Evaluation for pavement design which indicates a minimum or 2"AC/7"BC or 2.5"AC/5"BC.
16) Add reference to the soils report in a general grading note and include any associated addenda for Western Technologies Inc. Geotechnical Evaluation.
17) DS Sec.11-01.14.2&3: On planview sheet C2.2, label dimension of minimum setback from demarcation of ponding limits to edge of building footprint from the basin areas. This dimension should be at an acceptable distance per geotechnical recommendations.
18) There are depictions of drainage outlets from the PAAL areas into landscaped areas around the proposed building structures. Ponding from drainage areas should be minimized near foundations. Provide assessment of plans by the geotechnical engineer with recommendations of drainage setbacks from structures. Provide dimensions between swales and building structures on sheet C2.2.
19) DS Sec.10-01.4.3: Where human activity zones are located in basin areas, 8:1(H:V) side slopes are needed at location of pedestrian access, and shall not conflict with inlets to the basins. Label grades for side slopes in drainage basin areas.
20) DS Sec.10-02.14.3.4: Delineate access to basin areas on sheet C2.2 (minimum ramp size is 15 feet wide at 15% slope. Show that no proposed vegetation will block access on sheet L1.2.
21) Provide dimensions for basin areas for inspection purposes.
22) DS Sec.2-02.2.1.A.33. Show location of existing fire hydrants within 300 feet of the site boundaries on sheets C1.1 and C2.2.
23) PC/COT Stnd Det.207: Provide 12% grade on ramp for curb access on sheet C1.6.
24) DS Sec.2-02.2.1.A.20: All easements of record must be graphically shown on the plan together with recording docket and page reference. Show and label also the utility easements listed in Title Report. Acknowledge that if any easements are relocated, not in use, or proposed for abandonment, then the documentation of the vacation / abandonment / relocation shall be submitted. Any blanket easements should be listed in the notes, together with recordation data and their proposed status.
25) DS Sec.2-03.2.1.J: Remove grid lines at H/C ramps on planviews and provide notation, legend symbol, or a detail for the curb access ramps with notation to provide truncated domes per ADAAG. This is an update to COT standard detail 207.
26) DS Sec.2-02.2.1.A.32: Solid Waste Pick-up Discussion: An optional right-of-way is proposed for solid waste pick-up. The alternate onsite pick-up scenario has maneuverability issues and may impose more of a safety risk to a project with senior citizens and high pedestrian traffic. The option for the off-site pick-up appears to provide sufficient maneuverability, lessen the safety risks, and thus would be an acceptable option. Address the following solid waste pick-up comments:
a) DS Sec.6-01.4.2.C: State in response letter and clarify on plans whether detail shown on C1.4 will be built.
b) DS Sec.6-01.10.Fig.2: Submit copy of documentation from Solid Waste Department of Environmental Services (contact: John Clark) accepting solid waste pick-up access, maneuverability and details as shown on most recent plans.
