Principal Planner

Comments:

1. The grading plan has been reviewed by Zoning Review Section but cannot approve the plan at this time.

2. While zoning acknowledges that the grading plan is in substantial zoning compliance as it relates to the Zoning review purview, with the approved version of the tentative plat, the grading plan cannot be approved at this time. Prior to Zoning approval the Engineering and Landscape Sections must approve the grading plan.

3. Draw and label the 10' non-motorized public trail esm't. on sheets 6 and 7.

4. Label the tentative plat case number in the lower right coerner of all grading plan sheets.

5. Zoning is willing to review and approve the grading plan over the counter once the enginering and landscape sections have approve this plan.

Please call me to set up an appointment for a counter review and approval of the is grading plan.

2. Reference the subdivision case number in the lower right corner of all grading plan sheets.

3. Ensure that all Engineering & Zoning comments and concerns are addressed.

The Contractor may not use any other plans, such as the approved Tentative Plat and/or Development Plan, for construction purposes. The Contractor may ask the Development Services Inspector to consult with the other approved plans for additional information or details that might not be included on the approved grading plan but needed for completion of work.
b. The contractor shall remove the fine materials from the bottom of the detention/retention basin and scarify the basin bottom once the construction activities are completed in order to remove any fine material build up caused by construction and to restore soil percolation. Alternatively, the contractor may utilize BMP's at the basin inlet(s) to prevent the fines from entering the basin.
c. Add a note, which states that any engineering work to be done below grade (i.e. toe-downs, cutoff walls, drainage pipes/structures, etc.) shall not be back filled until Development Services Inspector inspects the work and approves it.

11- It appears that Lots 385-388 do not comply with the requirements of differential grading as described in Development Standard 11-01.8.0 Fills. Either readjust the said lot elevations or verify compliance with the requirements of D.S. 11-01.8.0.
12- According to the approved Drainage Report, Lots 393-395 and 385 are Type "A" lots. The Grading Plan shows those lots as "C" and "B" lots. Address this issue and discuss any possible adverse impact on the approved drainage scheme.
13- Show the wall between the lots on Detail 10/2.
14- Provide additional details for the proposed retaining wall shown on Lots 393-401 and 476 (i.e. length, height, cross sectional details, etc.). Please be advised that retaining walls may require separate permits.

18- The elevations shown on Detail 2/5 are different from the elevations shown in the Tentative Plat on the corresponding detail. Clarify the differences or revise as needed.
19- According to the approved Drainage Report, Lot 452 is a Type "A" lot. The Grading Plan shows this lot as "B" lot. Address this issue and discuss any possible adverse impact on the approved drainage scheme. Please be advised that lot to lot drainage is not acceptable (check also Lot 423).
20- The support beams, in Detail 1/5, appear to be floating in the air. Show all required detail that are needed to build the catch basin including the beams supports.
21- The pipes inverts, in Detail 1/5, appear to be different from the catch basin elevation where the pipes will be. Revise as necessary.
22- Clarify on Detail 8/3 that the flared end belong to the proposed drainage pipes.
23- Provide the slope of the emergency access described in Keynote #16, on Sheet 6 of 7.

26- Provide the dimensions of the grouted riprap pad on the right side of Detail 1/6.
27- Check the pipe slope in Detail 1/6 and revise if necessary.

37- All proposed cuts and fills shall be pulled back a minimum of 2' from the parcel line. Revise all applicable details accordingly.
38- Provide a detail that shows the proposed 6" orifice opening at the inlet of all detention basins bleed pipes. The orifice shall be installed closer to the pipes inverts.
39- Please be advised that since this project has been phased out into 8 different phases, it is assumed that grading all eight phases will not happen all at once. Grading plan approvals expire after 180 days from the date when the review fees are paid plus another 180 days if an extension is requested. Once the permit fees are paid, the developer has 180 days before the permit expires unless inspections are requested in a timely manner. Address this issue and determine if it is still the developer's wish to review all phases the same time.
