Encased Is the modified PCN for Bob Helms protect In Boone Mr Helms has modified the sate plan for
this probed but the purpose of the protect and all impacts to tunsduluonal waters remain the same as
previously permitted All proposed Impacts have occurred and there are no remaining waters of the US
or waters of the State on the project site As discussed with you and Annette Lucas the enclosed
package shows existing and proposed Impervious cover for the entire project site and demonstrates
compliance with the stornw ater management condition of WOC -3821 ENV Inc has prepared this
modfied application and Is available to answer any questions you may have If you need to schedule a
site visit please contact me Please Include ENV Inc on the copy list of all correspondence for this
project
If you have any questions regarding these Items please call me at 828 - 297-6946 thank you

Protect Description
3a
Describe the existing conditions on the site and the general land use in the vicinity of the protect at the time of this
application
Since the original permit application (Old PCN) was submitted for this project in October of 2010 the Applicant has
completed all proposed impacts to streams and wetlands proposed The protect to date has resulted in permanent
impacts to approximately 0 1 acres of wetlands and 64 linear feet of intermittent stream All pipes and associated
drainage structures proposed in the Old PCN have been installed There are no remaining Waters of the US on the
property The area of the property that contained the stream and wetland has been filled as shown in the Proposed Site
Plan dated 9-26 2010 from the Old PCN The disturbed areas have been stabilized with gravel or vegetation NCDOT
continues to use the area for staging of materials although the Hwy 421 widening project is winding down
3b
List the total estimated acreage of all existing wetlands on the property
0 0 acres
3c
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property
0 0 linear feet of streams
3d
Explain the purpose of the proposed project
The Applicant has determined that the most critical need for this property is to restore the parking that was lost due to the
Hwy 421 widening project Prior to the Hwy 421 protect the site contained 47 parking spaces and this was felt by the
Applicant to be only barely sufficient The current (existing) parking lot contains only 27 parking spaces NCDOT as part
of a settlement agreement with the Applicant agreed to replace the lost parking spaces up to 47 spaces The purpose of
this modified PCN is to show a change to the protect plans that reflects the replacemnt of the lost parking spaces and to
demonstrate compliance with all conditions of the previously issued CWA 404/401 permits
3e
Describe the overall project in detail including the type of equipment to be used
The Applicant intends to extend the existing parking lot to the west onto adjacent properties to bring to total number of
parking spaces to 47 plus 2 motorcycle spaces This activity will not involve impacts to Waters of the US there are no
Waters of the US located on the project site at this time The protect site has been modified from the Old PCN to include
4 additional parcels for a total project area of approximately 148 acres (see Modified Proposed Site Plan) The proposed
work will involve minimal new grading to expand the existing filled area slightly to the southwest and to blend the entire
area into the new driveway constructed by NCDOT The Dumpster pad will be relocated to ar area just west of the
current site entrance All parking and drive areas would be paved with asphalt Typical construction equipment would be
used including bull dozer track excavator dump trucks All graded slopes would be seeded and stabilized in accordance
with Town of Boone standards Site landscaping would also follow Town of Boone Standards

Bob Helms Project
Stormwater Management Narrative
The purpose of this narrative Is to characterize existing and proposed conditions on the project site with
respect to Impervious cover and to state the Applicants understanding of current and future
stormwater management requirements on the site Included with this narrative are the following maps
and related Information
1 Aerial photograph of project area taken prior to beginning of the Hwy 421 widening project
Shown on the aenal are the proposed edge of pavement and nght -of way Imes Parcels 1 and
2 as defined In this narrative are also labeled
2 Plan sheet #47 or 61 from DOT Title Plans for the Hwy 421 widening project In Boone NC
(downloaded from the NCDOT website) This sheet shows the boundary of the project area
with existing (pre Hwy 421 project) impervious cover on portions of all lots located outside of
the post Hwy 421 project right -of way
3 Plan sheet #48 of 61 from DOT Title Plans for the Hwy 421 widening project in Boone NC
(downloaded from the NCDOT website) This sheet shows the boundary of the project area
with existing (pre Hwy 421 project) impervious cover on portions of all lots located outside of
the post Hwy 421 project right -of way
4 Copy of current project plans prepared by Municipal Engineering Services
5 Table Bob Helms Site Pre and Post Site Imperviousness
Based on discussions with Annette Lucas (DWQ Stormwater) an evaluation of the project site was
performed to determine pre and post development impervious cover The property is divided into
Parcel 1 and Parcel 2 with Parcel 1 being the existing apartment building and parking Parcel 2
consists of the remaining 4 lots The boundaries of both parcels are drawn at the current (post Hwy
421 widening project) DOT R/W line for both pre and post - development Impervious determinations
The results of the Impervious cover evaluation show that the current project will result in a net overall
reduction in impervious cover of 1598 sq ft (2 48 %) from the pre - development condition over the
entire project area
This determination is based on the current proposed plan for development of the lot as depicted on the
attached Grading Plan prepared by Municipal Engineering and titled Robert F Helms Parking Lot
Revisions This plan differs from the previously permitted site plan in several ways
• The project site has been modified from the Old PCN to include 4 additional parcels for a total
project area of approximately 148 acres (see Modified Proposed Site Plan)
• This activity will not involve impacts to Waters of the US there are no Waters of the US located on
the project site at this time
• The proposed work will involve minimal new grading to expand the existing filled area slightly to the
southwest and to blend the entire area into the new driveway constructed by NCDOT
• The Dumpster pad will be relocated to an area dust west of the current site entrance
Based on communication with both Annette Lucas and Sue Homewood of DWQ It Is the Applicants
understanding that provided the project does not Increase the Impervious cover of the project area
there will be no specific stormwater management BMP s or pollutant removal targets required of the
Bob Helms Project 1 of 2 SWIM Narrative

Applicant at this time The Applicant understands that If at any time In the future the site Is further
developed beyond what Is shown on the attached plans all requirements of Condition #12 In WQC
#3821 must be satisfied The Applicant further understands that If the property Is sold the new owner
must be given a copy of the Certification and approval letter and will thereby be responsible for
complying with all applicable conditions
