There are still some inconsistencies between the plans. 2. The detail for the Vine Drive Drive / Impala Drive intersection is not adequate. 3. There is an 8% maximum slope requirement for drives. Some are shown to be 100/6. 4. The footings for the retaining wall cannot be in easements. 5. The Traffic Engineering Department has some striping comments. 6. There are some scanning issues associated with the plans. Please visit J.R. Wilson of Technical Services for his input. This completes staff (and outside reviewing agencies) review and comments at this time. Red -lined plan from City departments are included with this comment letter. Additional comments and red -lined plans may be forthcoming. Another round of staff review is determined to be necessary. This proposal is subject to the 90-day revision re -submittal requirement (from the date of this comment letter, being August 24, 2005) as set forth in Section 2.2.11(A) of the Land Use Code. Be sure and return all of your red -lined plans when you re -submit. The number of copies of each document to re -submit is shown on the attached Revisions Routing Sheet. If you have any questions regarding these issues or any other issues related to this project, please feel free to call me at 221-6341. Y urs Truly, Steve 1 , -- City Planner cc: Susan Joy DMW Engineers King Surveyors Current Planning File #42-03C Page 5 [9/3/04] The grading plan needs to clearly show that all drainage within a proposed basin that was designed to drain to the detention pond will actually drain to the pond after construction. Due to the building footprints being proposed very near the slope grading along the east and part of the south sides of the site, lots 1 through 4 may act more like Type B lots than Type A lots. This would result in drainage entering the private drive which can not be allowed. A retaining wall may have to be designed or the building footprints reduced and the grading plan has to clearly show that drainage will flow to the private drives west of the lots. Spot elevations need to be shown with high points, swale inverts, etc. which clearly illustrates the flows going around the structures and to the private drive. Number: 121 Created: 12/ 10/2004 [8/ 12/05] I will e-mail you the new water quality outlet structure detail. [ 12/ 10/04] The water quality outlet structure is not designed specifically to the site and there still is some missing design elements that are needed for construction. The City is developing a standard detail that can be used for this site and should be completed in a couple of weeks. Number: 152 Created: 8/ 15/2005 [8/ 15/05] The report needs to include pond sizing calculations including a stage -storage table. Topic: Erosiort/Sediment Control Number: 151 Created: 8/ 12/2005 [8/ 12/05] 1. There should be a note on the plan indicating what areas are to be seeded/mulched, and/or sodded (e.g. the WO pond, etc?). 2. Please put the most current erosion control notes on the plan. s****ssssssss*ssss*ss*sssssss***ssr*ss*•s*s**ss�**s*ss******s*s**sr*******ssss***s*** The following comments / concerns were expressed at the staff review meeting on August 10, 2005: Light & Power: 1.

Wilson in Technical Services with your plans regarding scanning requirements. [12/10/041 The plans still have scanning problems. Please see redlines - I've highlighted some of the problem areas in pink highlight. The shading doesn't scan at all and will need to be changed to some sort of hatching. [9/8/04] Correct all overlapped labeling and rotate all labeling to the reader. Do not shade areas of removal as this will not scan. Hatching works much better. Please see Appendix E6 for scanning requirements. [7/27/041 Please see Appendix E6 for scanning requirements.
