David,
I have reviewed the new plan sheet and the updated supplement forms. As I indicated in my previous email below: "we need to
see a report from a licensed professional to indicate that their determination was made in the location of the SCMs." You
included SHWT on the supplement forms but there's no documentation to indicate how you arrived at this information and to
confirm it was determined in the location of each sand filter.
Also, the new MDC require that all SCMs are accessible for maintenance and repair and the that SCM and accesses shall be shown
on the plans as located in a permanent recorded easement. Please see 15A NCAC 02H .1050 (8) and (9)

David,
Do you have an update on where things stand with this? I will probably need to write a letter this week formally requesting the
information that I still need in order to finalize my review of the SMP.

David,
The requirement for Sand Filters specifies a separation from the SHWT. In the "soils" chapter (A-2) of the new design manual,
they cover multiple topics. The first is soil media and in-situ soils infiltration rate. These are essential for some SCM's but are not
a requirement of Sand Filters. The only part of that chapter that would be required for this project is determining the depth to
season high water table. The information provided does not describe what is necessary for documentation of a SHWT but we
need to see a report from a licensed professional to indicate that their determination was made in the location of the SCMs. The
list of requirements you reference are for cases when you want to support allowing less than 2 feet of separation from the SHWT.
Thanks,
Sue Homewood

GRADING AND DRAINAGE NOTES:
1. EARTHWORK QUANTITIES HAVE BEEN ESTIMATED AND SITE AS SHOWN IS ASSUMED TO REPRESENT A
BALANCED CUT / FILL CONDITION. PROJECT OBJECTIVE IS TO GRADE AS MUCH OF FUTURE ADDITION AS
MATERIAL ALLOWS.
2. CONTRACTOR SHALL PERFORM HIS OWN ESTIMATE AND SHALL PROVIDE ALL EARTHWORK NECESSARY TO
ACHIEVE THE DESIGN GRADE, INCLUDING ANY OFFSITE BORROW OR SPOILS REQUIRED.
3. CONTRACTOR SHALL PROVIDE POSITIVE DRAINAGE IN ALL GRADED AREAS, INCLUDING PAVING, LAWN AND
LANDSCAPE AREAS.
4. THE CONTRACTOR SHALL IMMEDIATELY REPORT TO THE OWNER ANY DISCREPANCIES FOUND BETWEEN ACTUAL
FIELD CONDITIONS AND CONSTRUCTION DOCUMENTS AND SHALL WAIT FOR INSTRUCTIONS PRIOR TO
PROCEEDING.
5. CONTRACTOR SHALL VERIFY LOCATION OF ALL UNDERGROUND UTILITIES PRIOR TO BEGINNING WORK, BOTH
PUBLIC AND PRIVATE. CONTRACTOR IS FULLY RESPONSIBLE FOR ALL UNDERGROUND UTILITIES AND SHALL
REPAIR ANY DAMAGE AS A RESULT OF THIS CONTRACT.
6. CONTRACTOR SHALL BLEND NEW EARTHWORK SMOOTHLY TO TRANSITION BACK TO EXISTING GRADE.
7. THE PROPOSED CONTOURS AND SPOT ELEVATIONS SHOWN IN DRIVES, PARKING LOTS AND SIDEWALKS ARE
FINISHED ELEVATIONS INCLUDING ASPHALT. REFER TO PAVEMENT CROSS SECTION DATA TO ESTABLISH
CORRECT SUBBASE OR AGGREGATE BASE COURSE ELEVATIONS TO BE COMPLETED UNDER THIS CONTRACT.
8. ALL "STD." NUMBERS REFER TO THE (AGENCY) DEVELOPMENT STANDARDS.
9. ON-SITE BURIAL PITS REQUIRE AN ON-SITE DEMOLITION LANDFILL PERMIT FROM THE ZONING ADMINISTRATOR.
10. MAXIMUM CROSS SLOPE OF SIDEWALKS SHALL BE 1/4" /FT.
11. SLOPES SHALL BE GRADED NO STEEPER THAN 2:1. W/ OUT ADDITIONAL STABILIZATION MEASURES AND
PRIOR APPROVAL.
12. APPROVAL OF THIS PLAN IS NOT AN AUTHORIZATION TO GRADE ADJACENT PROPERTIES. WHEN FIELD
CONDITIONS WARRANT OFF-SITE GRADING, PERMISSION MUST BE OBTAINED FROM THE AFFECTED PROPERTY
OWNERS.
