A. Variance Request
The request of Matthew and Kathryn Cookston, property owners, for a variance from
Section 106-202.3(8)(1) of the City of Salem Zoning Ordinance pertaining to site
development regulations, for the property located at 436 Westland Street, Tax Map#
171-2-13. The petitioners are requesting a variance of 8.2 feet of side-yard setback
and 25 feet of rear-yard setback to allow an addition. Section 106- 202.3(B)(1) states
that a side-yard setback of ten percent (8.2 feet) and a 25 feet rear-yard setback is
required. Proper legal notice was given, and all adjacent property owners were
notified.
Chairman DuBois inquired if there was any correspondence. Ms. Wines responded
affirmatively that a phone call from a neighbor on the east side of the entrance to the
park was received. Once the proposal was explained the neighbor did not have any
issues with the request.
Chairman DuBois asked if the Board had a chance to view the property. All
members present responded that they had seen the property.
Chairman DuBois opened the public hearing and invited the petitioners to approach
the podium.
Mr. Matthew Peters with Covenant Engineering, 2728 Colonial Avenue, S.W.,
Roanoke, Virginia 24015, appeared before the Board. Mr. Peters stated that they
developed the drawings for the petitioners. He stated that the property owner, was
out of state and could not attend the meeting. He thought the reason for the request
was included in the packet.
Ms. Wines replied that the petitioners are requesting a variance to allow an addition
on the house for a large family room and full bathroom.
Vice-Chair Copenhaver asked if the addition would, in any way, extend into the
neighboring properties.
Mr. Peters replied that a survey was completed and that there was fourteen feet to
the property line and that the addition would not extend to the property line.
Vice-Chair Copenhaver inquired if the city had any objections to the request since it
is adjacent to the entrance to the park the city owns.
Ms. Wines responded that city management has reviewed the application and it is felt
that the addition will not impede with the pedestrian traffic into the park, so the city
has no opinion.
Mr. Sellers stated that from his observance that there is another eight feet or so
between the addition and the fence to the alley going into the park.
Ms. Wines replied that the fence that is marked on the plat is nine feet into the City’s
property. They have since put up a fence on their property line so the secondary
fence, the fence to the west, shows the actual property line.
Vice-Chair Copenhaver stated that the fence along the entrance into the park has not
been moved. Would the city have any interest in trying to reclaim those nine feet by
forcing them to move the fence back.
Ms. Wines answered that the City was not going to take action at this time but if it
was ever necessary to utilize the full width of the entrance that they could come
through and remove the fence that encroaches into city property.
Chairman DuBois asked if the petitioner requested to have the alley vacated.
Ms. Wines responded that the petitioner did not submit an official request, but the
city would not necessarily consider the request due to the traffic that utilizes this park
entrance.
Mr. Gresham asked if staff knew that when the neighborhood was developed that
there was some sort of error and there was incorrect information at that time.
Ms. Wines replied that she was not aware of that, that the pictures on the GIS were
not completely accurate, but that the property lines should be correct.
Chair DuBois asked how much actual space is there between the corner of the
addition and the property line.
Mr. Peters replied one foot.
Mr. Sellers inquired if there was to be an overhang on the addition that would
encroach into the one foot.
Mr. Peters stated not that it is a flush gable end on that one wall.
Chairman DuBois inquired if the city would ever be interested in widening the park
entrance.
Ms. Wines responded that there are two other entrances to the park and staff does
use the northern entrance for equipment and the entrance in question is typically just
pedestrian traffic.
Chairman DuBois asked if there was anyone else to speak on this matter
Mr. Dustin Wimbush of 426 Westland Street appeared before the Board. He stated
he is the neighbor closest to the addition. He fully supports their request.
Chairman DuBois asked if there was anyone else to speak on this matter and hearing
none closed the public hearing.
Chairman DuBois asked the Board for any discussion and hearing none he would
entertain a motion.
Mr. Gresham motioned to grant a variance of 8.2 feet of side-yard setback and 25
feet of rear-yard setback to allow an addition. Mr. Sellers seconded the motion.
Ayes: DuBois, Copenhaver, Gresham, Sellers
Absent: Derr, Eanes, Belanger

A. Variance Request
The request of Richard E. and Betty W. Bryson, property owners, for a variance
from Section 106-202.3(B)(1) of the City of Salem Zoning Ordinance pertaining
to site development regulations, for the property located at 1507 Millwood
Drive, Tax Map # 205-1-2.4. The petitioners are requesting a variance of 9 feet
of side-yard setback to allow a carport addition. Section 106-202.3(B)(1) states
that a side-yard setback of ten percent (9.0 feet) is required.
Chairman DuBois inquired if there was any correspondence. Ms. Wines responded
affirmatively that a phone call from Mr. Clinton Frost, property owner of 1509
Millwood Drive called to voice his support of the request.
Chairman DuBois asked if the Board had a chance to view the property. All
members present responded that they had seen the property.
Chairman DuBois opened the public hearing and invited the petitioners to approach
the podium.
Mrs. Betty Bryson, 1507 Millwood Drive, Salem, appeared before the Board. Mrs.
Bryson stated that they would like to construct a carport. It could be enclosed, or an
open carport would be fine. They just need cover from the weather for their car for
safety reasons for her husband. This is their retirement home. Her husband is an
100% disabled veteran. He has trouble with falling. This home is one level. They
have had floor work done to make sure there are no trip hazards. Whenever there is
inclement weather, they need the car cover to safely get him in and out. He has had
surgeries and has been in a wheelchair. This home allows for the wheelchair because
it is flat going into the home.
Vice-Chair Copenhaver inquired as to how it would attach to the home. Will it be
attached to the house or will it be freestanding.
Mrs. Bryson replied that she had only gotten one estimate and they wanted to do
what drill down into the concrete that is there and put in footers. The wall clearly has
an excellent footer. They said they could not tie into the house that it has to have
separate supports. She does not want to drill into the existing concrete if she does
not have to.
Chairman DuBois asked if the structure was a permanent structure and not a portable
carport.
Mrs. Bryson stated that she wants a permanent one that ties into the way the house
looks.
Mr. Gresham questioned if under those conditions they would attach it to the house.
Mrs. Bryson replied that it would have separate supports, but they will tie into the
roof of the existing house.
Chairman DuBois asked if there was anyone else to speak on this matter and hearing
none closed the public hearing.
Chairman DuBois asked the Board for any discussion and hearing none he would
entertain a motion.
Mr. Belanger motioned to grant a variance of nine feet of side-yard setback to allow
a carport addition. Vice Chair Copenhaver seconded the motion.
Ayes: DuBois, Copenhaver, Gresham, Belanger
Absent: Derr, Eanes, Sellers
B. Variance Request
The request of Richard H. and Elizabeth K. Macher, property owners, for a
variance from Section 106-204.3(B)(2) of the City of Salem Zoning Ordinance
pertaining to site development regulations, for the property located at 1900
South Clearing Road and 1900 block South Clearing Road, Tax Map #s 277-1-4
and 285-13-1, respectively. The petitioners are requesting a variance to allow
the construction of a 28' x 22' pool house and 16' x 32' pool in the side yard.
Section 106-204.3(B)(2) states that accessory structures must be built behind
the rear building line of the principal structure (or in the rear yard).
Chairman DuBois inquired if there was any correspondence. Ms. Wines responded
affirmatively that letters had been received in opposition of the request from Virginia
Mosnoss, and Dorothy Thomas, property owners of 2500 Oak Ridge Lane and Mrs.
Sylvia Williams, property owner of 2502 oak Ridge Lane.
Chairman DuBois asked if the Board had a chance to view the property. All
members present responded that they had seen the property.
Chairman DuBois opened the public hearing and invited the petitioners to approach
the podium.
Mr. Jason Lucas, contractor, 2030 Shenandoah Avenue Roanoke, Virginia. The
owners would like to put a 16 x 32 pool to the left of the house and 22 x 28 pool
house beyond that. Single story 19.5 foot tall from finished grade. There are two lots
that need to be combined. There is no backyard to speak of except for the driveway
in the rear. There is no possibility of putting a pool house behind the house. They
have a huge lot in the front, left and right as well.
Vice-Chair Copenhaver inquired as to how tall, in response to one of the letters
received, will the pool house be in relation to the current structure.
Mr. Lucas responded that the pool house would be 19.5 foot tall, and the grade of
the yard is above the neighbors down below. In relation to the existing house, it will
be between the first and second floor of the house.
Chairman DuBois questioned if the structure was a single-family house or an
apartment building.
Mr. Lucas stated that one section of the house is rented.
Vice-Chair Copenhaver inquired if the existing house was part of the homeowner’s
association of the neighborhood.
Mr. Richard Macher, owner, appeared before the Board stating that this was the old
McVitty House. There is no back yard. The pool would not fit with the required
setback. The reason it is two lots is that the original lot was 1.4 acres. He ended up
buying the rest of the land to protect the house. The deed restricted building to
tennis courts, pool and garage. There are two parcels not included in the
homeowner’s association. The carriage house lot and the lot with the old McVitty
House. One of the restrictions on the development was that no structure could be
built higher than the first floor of the McVitty House. The view will not be altered
because the neighboring houses roofline is at or below the grade of his property.
Mr. Belanger asked if he lived in the side of 1900.
Mr. Macher responded affirmatively. The house is 24,000 square feet. Who could
ever live in 24,000 square feet. There were 6 apartments when he purchased the
property and as his family grew the 6 apartments ended up becoming 2 apartments.
They have a totally separate entrance.
Mr. Belanger asked if they enter on the opposite side from the proposed pool.
Mr. Macher responded affirmatively.
Chairman DuBois asked if the pool would be open to the tenants and their guests.
Mr. Macher responded that yes because they are mostly family, but it would not be a
community pool. He further stated that the neighboring properties were all blocked
by trees.
Chairman DuBois inquired if the pool house would be on the lot that has not been
joined with the rest of the property.
Mr. Macher replied yes.
Chairman DuBois responded that they would have to submit a combination plat. He
asked staff if that had been submitted as of yet.
Ms. Wines responded that it had not been submitted as of yet. But it could be a
condition of the Board’s approval if they so choose. They would be unable to obtain
a building permit if the combination plat were not submitted and approved.
Chairman DuBois asked staff if the 17-foot setback shown would be sufficient.
Ms. Wines responded affirmatively that the required setback would only be five feet.
After further discussion, Chairman DuBois asked if there was anyone else to speak on
this matter and hearing none closed the public hearing.
Chairman DuBois asked the Board for any discussion and hearing none he would
entertain a motion.
Vice Chair Copenhaver motioned to grant a variance to allow the construction of a
28 x 22-foot pool house and a 16 x 32 pool in the side yard on the condition that
the two lots be combined. Mr. Belanger seconded the motion.
Ayes: DuBois, Copenhaver, Gresham, Belanger

Sec. 106-226.9. Variances.
(A) The Board of Zoning Appeals, in accordance with section 106-528, may consider petitions for variance(s)
from the provisions of this chapter; provided, however, that all relevant factors pertaining to the danger to
life and property caused by increased flood levels and velocities due to encroachments are thoroughly
examined. In considering applications for variances, the Board shall consider the following factors:
1. The danger to life and property due to increased flood heights or velocities caused by encroachments.
2. The danger that materials may be swept onto other lands or downstream to the injury of others.
3. The proposed water supply and sanitation systems and the ability of these systems to prevent disease,
contamination and unsanitary conditions.
4. The susceptibility of the proposed facility and its contents to flood damage and the effect of such
damage on the individual owners.
5. The important of the services provided by the proposed facility to the community.
6. The requirements of the facility for a waterfront location and a location within a floodplain district.
7. The availability of alternate locations not subject to flooding for the proposed use.
8. The compatibility of the proposed use with existing development anticipated in the foreseeable future.
9. The relationship of the proposed use to the comprehensive plan and floodplain management program
for the area.
10. The safety access to the property by ordinary and emergency vehicles in times of flood.
11. The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters
expected at the site.
12. Such other factors which are relevant to the purposes of this division.
(B) No variance shall be granted for any proposed use, development or activity within any floodway district,
except in full compliance with all of the following requirements:
1. The variance will not cause any increase in flood levels during the 100-year flood. (Appropriate
documentation from a registered engineer must be submitted which substantiates the impact on flood
heights, velocities and flows through hydrologic and hydraulic analyses and calculations.) If the
variance involves any alterations or relations to a floodway or its channel, such alterations or
relocations shall also be approved as required by law.
(C) The Board of Zoning Appeals shall notify the applicant for a variance(s) in writing that the issuance of a
variance(s) to construct a structure below the 100-year flood elevation:
1. Increases the risks to life and property; and
2. Will result in increased premium rates for flood insurance.
(A) A record of the notification, as well as all variance actions, including justification for their
issuance, shall be maintained, and any variances which are issued shall be noted in the annual
report submitted as required by law.
(B) Variances may be issued for the reconstruction, rehabilitation or restoration of structure listed
on the National Register of Historic Places or the state landmarks register without regard to the
procedures set forth in this section.
(C) Requirements for granting a variance within the floodplain shall be as follows:
Created: 2022-12-07 11:23:51 [EST]
(Supp. No. 23, Update 1)
Page 2 of 2
1. The failure to grant the variance would result in exceptional hardship to the applicant;
2. The variance will be the minimum relief to any hardship; and
3. The granting of such variance will not result in:
a. Unacceptable or prohibited increases in flood heights;
b. Additional threats to public safety;
c. Nuisances;
d. Fraud or victimization of the public; or
e. Conflicts with local laws or ordinances.
4. The applicant has shown a good and sufficient cause to justify the variance.

West Roanoke River Greenway
Roanoke County / City of Salem, VA
July 16, 2019
Executive Summary
The design plans for the West Roanoke River Greenway Project located in Roanoke County, VA
proposes the construction of two (2) bridges to span the Roanoke River. Both bridges are to be
situated within the Special Flood Hazard Area (SFHA or 100‐year Floodplain) and the Regulatory
Floodway (or a portion thereof) of the Roanoke River. In addition, a portion of the greenway trail
design (generally between trail stations 61+00 through 80+50) will result in a trail alignment and
cross section that utilizes a gabion basket / reinforced earth retaining wall section that results in
placement of fill in the Floodway/Floodplain. In order to evaluate compliance with Roanoke
County, City of Salem, and Federal Emergency Management Agency (FEMA) Floodplain and
Floodway Regulations, a Hydraulic Analysis of the proposed bridges and fill‐based sections of the
trail alignment was performed.
Bridge 1 is proposed to be located +/‐ 83‐feet upstream of Diuguids Lane. The bridge design and
the hydraulic analysis indicated a bridge spanning the river at this location would be +/‐ 230‐feet
in span length and the low‐chord of the bridge would need to be set at elevation 1052.00. The
hydraulic analysis indicated a “no‐rise” in the base flood elevation (BFE) can be obtained with this
configuration (the placement of the structure 1‐foot above the base flood elevation) and by
incorporating side‐slope/flood channel modifications or “compensatory cuts” along the trail
alignment immediately downstream of the proposed bridge.
Bridge 2 is proposed to be located +/‐ 2,890‐feet downstream of Diuguids Lane. The bridge
design and the hydraulic analysis indicated a bridge spanning the river at this location would be
+/‐ 155‐feet in span length and the low‐chord of the bridge would need to be set at elevation
1044.5. The hydraulic analysis indicated a “no‐rise” in the Base Flood Elevation can be obtained
with this configuration (the placement of the structure 1‐foot above the base flood elevation)
and by incorporating side‐slope / flood channel modifications or “compensatory cuts” along the
trail alignment just upstream and downstream of the proposed bridge.
In the portion of the trail alignment where gabion basket/reinforced earth retaining wall sections
were used various alternatives were considered. The alternative that resulted in the most
desirable results included bench‐cuts along the toe of the trail and wall where feasible, and the
incorporation side‐slope / flood channel modifications or “Compensatory Cuts” in the immediate
vicinity.
This hydraulic analysis was performed using trail alignments, bridge crossing locations and
geometries, and elevations shown on the plans dated October 19, 2018 and marked as “Final
Plans / Not for Const.” The hydraulic analysis should be updated if the final design is modified
due to final review and approval comments.

1. Project Description/Background:
a. The County of Roanoke, in conjunction with the City of Salem, is proposing to construct a
new phase of the Roanoke River Greenway Trail entitled “The West Roanoke River
Greenway Project.” This phase of the Greenway will connect an existing greenway at
Green Hill Park (the western terminus) with the existing greenway at Riverside Park (the
eastern terminus).
b. The studied and recommended alternatives for the trail alignment were presented in a
Report prepared by Hurt & Proffitt entitled “Preliminary Engineering Summary Report /
West Roanoke River Greenway / Roanoke County & City of Salem, Virginia,” dated August
18, 2014.
c. The selected trail alignment (Alternative 4) features two spans crossings of the Roanoke
River and +/‐ 2,500‐feet of trail that traverses a section of steep slope between the
Roanoke River and West Riverside Drive. These components, which are incorporated into
the final design, will result in the placement of fill within the regulatory Floodplain and/or
Floodway and are the primary focus of this Report.
d. The work of the project being evaluated herein is shown on plans entitled “West Roanoke
River Greenway / City of Salem & Roanoke County, Virginia” as prepared by Hurt & Proffitt
are dated October 19, 2018 and are marked “Final Plans / Not for Const.”
e. Mattern & Craig, through a sub‐consulting agreement with Hurt & Proffitt, has been
commissioned to evaluate the hydraulic impacts of the proposed bridges and the
greenway trail along the severe sloping section of the trail (stations 61+00 through
80+50).
f. This report is based on the trail and bridge drawings / design that are assumed to be final.
The hydraulic analysis, results, and regulatory requirements must be updated if the trail
alignments and bridge locations / geometry are revised during the review and approval
process.

2. Project Objectives/Goals:
a. The critical benchmarks for the evaluation and analysis of the design of the structures and
trail proposed to be constructed within the Floodplain and Floodway will be local codes
and ordinances that are established to comply with the National Floodplain Insurance
Program (NFIP). Since the project will be located within the County of Roanoke and the
City of Salem, the codes and ordinances of each municipality must be evaluated and
satisfied. Below is a reference to and summary of key ordinances that will apply to this
project.
b. Roanoke County Code (Sec. 30‐74‐9) states: “In the flood‐fringe, special floodplain and
approximated floodplain the development and/or use of land shall be permitted in
accordance with the regulations of the underlying zoning district provided that all such
uses, activities, and/or development shall be undertaken in strict compliance with the
flood‐proofing and related provisions contained in the Virginia Uniform Statewide Building
Code and all other applicable codes and ordinances.” “However, in the special floodplain
and the approximated floodplain areas the applicant and/or developer shall evaluate the
effects of the proposed development and/or use of land on the floodplain with current
hydrologic and hydraulic engineering techniques. The applicant and/or developer shall
submit studies, analysis, computations, etc. to show the delineation of a Floodway based
on the requirement that all existing and future development not increase the one hundred‐
year flood elevation more than one (1) foot at any point. The engineering principle, equal
reduction of conveyance, shall be used to make the determination of increased flood
height.”
c. Roanoke County Code (Sec. 30‐74‐8) states: “In the Floodway no development shall be
permitted except where the effect of such development on flood heights is fully offset by
accompanying improvements which have been approved by all appropriate authorities as
required above.”
d. City of Salem Code (Sec. 106‐226.7) states: “Generally, under no circumstances shall any
use, activity, stream bed alteration or relocation, new construction, substantial
improvements and/or development adversely affect the capacity of the channels or
Floodways of any watercourse, drainage ditch or any other drainage facility or system. In
Floodways, no encroachments, fill, new construction, substantial improvements or other
development shall be permitted, except where the effect of such development (as may be

permitted in accordance with the regulations of the underlying zoning district) on flood
heights is fully offset by accompanying improvements which have been approved by
appropriate local, state and/or federal authorities as required by law (i.e., no proposed
use, development or activity shall be permitted within the Floodway which would cause
any increase in flood levels during the 100‐year flood).”
e. Additional regulatory guidance recently provided by FEMA, and local Floodplain
Managers state that in areas where there was incidental and nearly linear filling within
the Floodway, no impacts were deemed to occur if there is a balancing of the cut/fill
within the Floodway in the general vicinity of the area of fill (e.g. 200‐feet upstream and
200‐feet downstream). That is to say, there must be an equal or greater amount of cut in
the Floodway immediately adjacent to any proposed fill area. If these criteria cannot be
met, then the requirement of a “no net rise” (i.e., a 0.00‐foot rise) must be demonstrated
through hydraulic analysis. We understand that this guidance may only be applied to
incidental fill resulting from the trail construction and may not be utilized for bridge and
structure components.
f. To meet the intent of the applicable codes and to minimize effort and time required to
obtain FEMA Approved Conditional Letter of Map Revision (CLOMR) & Letter of Map
Revision (LOMR’s), the goals for the placement of the bridge structures were stated as
follows:
i. The low chord of the bridge structure should be at least one (1) foot above the
regulatory Base Flood Elevation (BFE).
ii. Wherever possible, all bridge structure(s) and associated fill should be located outside
the regulatory Floodway limits.
iii. Where it’s not possible to locate all bridge structure(s) and associated fill outside the
regulatory Floodway limits, the design team will perform a detailed hydraulic analysis
(consisting of an Effective and Proposed Conditions Model) and, if required,
incorporate appropriate counter‐measures (e.g. bench‐cuts or compensatory cuts) to
demonstrate that a 0.00‐foot rise may be obtained.
iv. Where the trail alignment is within the regulatory Floodway, confirm that there is a
no‐fill condition, or evaluate options to off‐set any fill and obtain a “no net fill” balance
in the immediate vicinity (+/‐ 200‐feet upstream and +/‐ 200‐feet downstream) of the

proposed fill through the use of “Compensatory Excavation.” This may include
lowering the trail grade/elevation or performing additional “bench cuts” in the
immediate vicinity of the filling.
v. If the above criteria can be met, it is assumed that only local (i.e. County of Roanoke
/ City of Salem) approval is required and a Conditional Letter of Map Revision (CLOMR)
will not be required.
3. Data Source:
a. The Floodplain and Floodway limits for this analysis are taken from the September 28,
2007 Flood Insurance Rate Map (FIRM) / Map Numbers 51161C0136G, 51161C0137G,
51161C0138G, and 51161C0139G (shown on APPENDIX A). The Floodplain (Special Flood
Hazard Area) and Floodway limits from the above‐reference source are shown plotted on
the greenway trail drawings and related exhibits prepared by Hurt & Proffitt.
b. Base Flood Elevations and Hydraulic Analysis Model:
i. The Base Flood Elevations (BFE) used in this Report and referenced on the Plans and
Exhibits are taken from the Flood Insurance Rate Map (FIRM), the Flood Insurance
Study (FIS), and the Hydraulic Analysis Model (HEC‐RAS) provided by Roanoke County
and FEMA for use in executing the work of this project.
ii. The Hydraulic Analysis Model was provided by Roanoke County and FEMA in HEC‐2
format. The Model covered the reach of the Roanoke River from Colorado Street in
Salem, VA (eastern terminus) to the Roanoke/Montgomery County line (western
terminus). The Model was converted into HEC‐RAS format for use in this study.
4. Description and Analysis of Proposed Bridge Crossings and Trail Fill Section:
a. General: As stated in the introduction, the recommended trail alignment results in two
(2) proposed bridge crossings. For consistent referencing, the proposed bridges are
numbered on the plans and exhibits used herein and in other related reports. Below is a
general description of each bridge along with a narrative of the issues related to hydraulic
performance of each bridge, and a statement of general compliance with the applicable
Floodplain/Floodway regulatory requirements.

Page 5 of 12
b. Bridge 1:
i. General Description: Bridge 1 is proposed to be located +/‐ 83‐feet upstream of
existing Diuguid’s Lane. The proposed bridge is shown on Plan Sheets C‐03 and S‐3 /
S‐4 of the Plans entitled “West Roanoke River Greenway” as prepared by Hurt &
Proffitt and Mattern & Craig. The proposed Bridge is located between trail stations
12+33 and 14+70. The Bridge is located within the Hydraulic Model at River Station
(R.S.) 84903. The Base Flood Elevation (1‐percent Annual Chance Flood elevation) at
the proposed crossing is elevation +/‐ 1051 (as taken from the Flood Insurance Rate
Map (FIRM) – Map Number 51161C0138G, dated September 28, 2007). A review of
the FIRM also indicated the proposed northern bridge abutment will not be within the
regulatory Floodway, while the southern bridge abutment will be located within the
Floodway. See Exhibits in APPENDIX B of this report showing the plan view of Bridge
1.
ii. Summary of Floodplain / Floodway related issues that affect the design / placement
of Bridge No. 1:
1. The general profile / cross section of the crossing and the hydraulic analysis
indicated a bridge spanning the river at this location would need to be +/‐ 234‐
feet in span length (nominal), with a clear span of 231‐feet and 4‐inch, and the
low‐chord of the bridge would need to be at elevation 1052.0.
2. Using the general parameters established for the preliminary bridge design, this
would result in a top of deck elevation of 1055 (see trail profile on plan Sheet C‐
03) and would situate the low chord of the structure at least 1‐foot above the Base
Flood Elevation.
3. Using the above stated general criteria and given the existing ground elevation at
each end of the proposed bridge is between 1048.5 (south side) and 1047 (north
side) it was determined that an elevated entry/exit landing structure and ramp
would be required at each end of the proposed bridge. The south landing is
directly adjacent to the existing trail and parking lot such that the landing
elevation is 1055 and a ramp (extending south and west) is required to slope down
to the trail grade situated at elevation 1048.5. See the trail profile on Sheet C‐03.

West Roanoke River Greenway
Roanoke County / City of Salem, VA

Page 6 of 12
The north landing structure would connect to the new / proposed trail with a
structure landing elevation at trail elevation 1055 and a ramping trail extending to
the west and to sloping down to the proposed trail grade of elevation 1040. It is
noted that these “landing structures” and ramping trail sections (constructed with
reinforced earth walls) are located within the Floodway and will be modeled as
fill.
4. The hydraulic analysis indicates a “no‐rise” in the base flood elevation can be
obtained with this configuration if bench cuts are incorporated along the north
bank of the Roanoke River between trail sections 18+50 and 31+50. Refer to
Section 5 of this Report for a summary of the model results.
c. Bridge 2:
i. General Description: Bridge 2 is proposed to be located +/‐ 2,890‐feet downstream
of Diuguids Lane. The proposed bridge is shown on Plan Sheet C‐06 and S‐7 / S‐ 8 of
the Plans entitled “West Roanoke River Greenway” as prepared by Hurt & Proffitt and
Mattern & Craig. The proposed Bridge is located between trail stations 50+41 and
51+96. The Bridge is located within the Hydraulic Model at River Station (R.S.) 81+943.
The Base Flood Elevation at the proposed crossing is elevation +/‐ 1043.5 (as taken
from the Flood Insurance Rate Map (FIRM) – Map Number 51161C0138G, dated
September 28, 2007). A review of the FIRM also indicated the proposed bridge
abutments are located within the Floodway.
ii. Summary of Floodplain/Floodway related issues that affect the design / placement of
the Bridge:
1. The general profile / cross section of the crossing and the hydraulic analysis
indicated a bridge spanning the river at this location would need to be +/‐ 155‐
feet in span length (nominal), with a clear span of 151‐feet 10‐inches, and the low‐
chord of the bridge would need to be at elevation 1044.5.
2. Using the general parameters set up for the preliminary bridge, this would result
in a top of deck elevation of 1046.2 and would situate the low‐chord of the
structure at least 1‐foot above the base flood elevation.

3. Using the above stated criteria and given the existing ground elevation at each
end of the proposed bridge is between elevation 1036 and 1035 on both the north
and south side, it was determined an elevated entry / exit landing structure and
ramp would be required at each end of the proposed bridge. The south landing is
situated between the top of the river bank and West Riverside Drive and the new
/ proposed trail continues east from this point. Based on this condition, it is
assumed that the landing elevation would be 1046.2 and a ramp would be
required to slope down to the trail grade situated at elevation +/‐ 1034 near trail
station 53+50. The north landing structure would connect to the new/proposed
trail, so it is assumed that the landing structure elevation would also be 1046.2
(top of bridge deck) and a ramp toward the west would be required to slope down
to the proposed trail grade at an elevation of +/‐ 1035 at trail station 48+80. The
trail profile in this vicinity is shown on Plan Sheet C‐06. It is noted that these
“landing structures” are located within the Floodway and will be modeled as fill.
While the landing structures are proposed to be solid fill structures, the ramps are
proposed to be span / truss structure. See Plan Sheets S‐3 and S‐4 for additional
detail.
4. The hydraulic analysis indicated a “no‐rise” in the base flood elevation can be
obtained with this configuration if side‐slope/flood channel modifications
between station 36+00 and 43+00 and 46+00 and 49+00 are incorporated into the
design. Refer to Section 5 of this Report for a summary of the model results.
d. Trail Fill Section:
i. General Description: the trail alignment / design through the steep slope section
between Trail Stations 61+00 and 80+50 would generally be developed by the use of
a gabion‐lined (faced) basket reinforced earth‐fill wall and trail section that would be
place generally at or near the 10‐years water surface elevation. See Plan Sheets C‐07
& C‐08 for additional detail.
ii. The height of the wall varies from a low of 0‐feet to a maximum height of near 22‐feet
(between trail station 76+50 and 78+00).
iii. Approach to off‐setting increase in base flood elevation:
Hydraulic Analysis of Proposed Bridges & Trail Fill Sections

Roanoke County / City of Salem, VA

Page 8 of 12
1. The original “Study Alternatives Analysis” reviewed five different alternatives for
off‐setting potential increases in the base flood elevation due to these trail fill
sections. The alternatives evaluated included incorporating bench cuts into the
slope above the trail and along the toe of the trail. Further geotechnical analysis
have determined that the slope may not be stable enough to implement cut and
fill bench operations. Based on this information, a revised approach was
developed and is outlined below.
2. Between trail stations 57+00 and 61+00 implement bench cuts along the toe of
the wall where grade, slope stability, and minimizing impacts to jurisdictional
water will permit. See cross sections on Plan Sheet C‐20.
3. Between trail stations 61+50 and 69+00, where the gabion‐faced reinforced earth‐
fill wall trail section are used, implement bench cuts and general excavations of
channel overbank area. This area is identified as Compensatory Cut Area No. 1.
This area is anticipated to generate up to 1,765 cubic yards of compensatory cut.
4. Between trail stations 80+00 and 85+00 the trail grade is lowered to maximum
extent possible (where elevation, slope stability, and minimizing impacts to
jurisdictional water will permit) to generate cut and off‐set fill from upstream
sections. This area is anticipated to generate up to 1,000 cubic yards of
compensatory cut.
5. These proposed modifications result in a ‐0.13 to ‐0.01 foot decrease in the Base
Flood Elevations along and immediately upstream of the trail fill sections. Since
the proposed trail will result in fill in the Floodway at this location the regulatory
requirement is that the rise in the BFE must not exceed 0.00‐feet. Based on the
results of the hydraulic analysis model, the regulatory requirement is met with
this alternative.

5. Summary of Results:
a. General: Upon completion of the hydraulic analysis model updates, the models were run
and the resulting base flood elevations (the 100‐year discharge / 1% annual chance flood)
for each cross section near the proposed bridge crossing were compiled and compared.
The results of the analysis are provided in the Summary Output Tables contained as
APPENDIX C. A general narrative and comparison of the results between the Existing /
Effective Conditions and Proposed Conditions Model for each proposed bridge is provided
below.
b. Bridge 1: The proposed bridge with associated mitigation cuts results in a 0.00 to ‐0.02
foot change in the Base Flood Elevations immediately upstream of the bridge. Since fill is
to be placed in the Floodway at this location, the regulatory requirements are that a 0.00‐
foot rise be demonstrated. To achieve the required 0.00‐foot rise, counter‐measures
were included in the cross section immediately downstream of the proposed bridge.
These measures included bench‐cuts along the northern bank between trail stations
18+50 and 32+00 to accommodate the location of the proposed trail. Based on the results
of the hydraulic analysis model, a 0.00‐foot rise is obtained and the regulatory
requirement is met. See a summary of the results in Table 1 – Summary Results for Bridge
1.

c. Bridge 2: An initial analysis of the proposed bridge resulted in a 0.11 to 0.20 foot increase
in the Base Flood Elevations (BFE) immediately upstream of the bridge. Since fill is to be
placed in the Floodway at this location, the regulatory requirements are that a 0.00‐foot
rise be demonstrated. To achieve the required 0.00‐foot rise, counter‐measures were

included in the cross sections immediately upstream and downstream of the proposed
bridge. These measures included a 10 to 20‐foot wide bench‐cut along the northern bank
between trail stations 36+00 and 43+00 and 46+00 and 49+00 in the area where the trail
is to be constructed. Utilizing the revised cross sections the results of the hydraulic
analysis model indicate a 0.00‐foot rise is obtained and the regulatory requirement is met.

ii. The proposed alternative results in a ‐0.13 to ‐0.01 foot decrease in the Base Flood
Elevations immediately upstream of the trail fill. Since there is fill in the Floodway at
this location the regulatory requirement is that the rise in the BFE must not exceed
0.00‐feet. Based on the results of the hydraulic analysis model, the regulatory
requirement is met with this alternative.

APPERSON DRIVE BRIDGE REPLACEMENT
OVER ROANOKE RIVER
UPC #110574
Narrative of Floodplain/Floodway and Scour Analysis
Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574)
Salem, Virginia
October 6, 2022
Page 1 of 6
Purpose/Project Description:
This narrative is provided to outline the known Floodplain/Floodway issues related to the proposed
bridge replacement and provide preliminary Hydraulic Analysis/Modeling of the proposed
improvements in an order to determine the impacts on the Regulatory Floodplain and Floodway and
related permitting issues. This narrative also provides a preliminary evaluation of scour concerns and
potential countermeasures. The information herein is based on plans and design details that are
approximately 90% complete. This narrative and the hydraulic analysis/modeling will be updated as the
design is completed.
The project involves the proposed removal of the existing bridge superstructure (girders, deck, and
roadway), lengthening of existing abutments and pier to accommodate the new wider bridge, and
reconstruction construction of a new bridge. The existing sub-structure (abutments and piers) will
remain. Refer to the current design plan for detailed information regarding project improvements.
Floodplain/Floodway Hydraulic Conditions at Existing Bridge:
In the vicinity of the project the Roanoke River flows under Apperson Drive and generally flows in a
north to south direction. The normal water surface elevation in the channel at this location is
uncontrolled by downstream structures (dams or levees) and typically assumes normal hydraulic depth
upstream and downstream of the bridge. The Roanoke River crosses under Colorado Street +/-
5,160-feet upstream, and crosses under Electric Road (U.S. 419) +/- 2,350-feet downstream of the
project area.
The project area is shown on Federal Emergency Management Agency (FEMA) - Flood Insurance Rate
Map (FIRM) - Map Number 51161C0143G, dated September 28, 2007. The project area is within an area
designated as Special Flood Hazard Area - Zone AE, an area where the Base Flood Elevations have been
determined, and the area is within a designated Floodway. The floodway width at the bridge crossing as
taken from the FIRM is +/- 430-feet wide. A copy of the FIRM Map, Firmette and Floodway Table are
provided in Appendix A.
A review of the FIRM shows that the Base Flood Elevations (BFE) in the vicinity of the bridge ranges from
997 to 996. A review of the Flood Profile from the Flood Insurance Study (FIS) report indicates that the
existing bridge is overtopped during the 1% Annual Chance Flood. The Flood Profile indicates the water
surface profile for the 1% Annual Chance Flood at the bridge crossing is between 997 and 996 – which
corresponds to the elevation on the published FIRM. The top of bridge is shown on the Flood Profile at
elevation +/- 904. The Flood Profiles in the project area are shown in Appendix B.
Mapping developed during the design phase indicates that Apperson Drive slopes from east to west at
approximately 1.09-percent slope with the elevations at the west and east abutments +/- 994.2 and +/-
995.9 respectively.
Based on data from the Flood Insurance Study (FIS), the drainage area of the Roanoke River at the
crossing with Apperson Drive is between 315 and 365-square miles. The flow rate for the 1-percent
Narrative of Floodplain/Floodway and Scour Analysis
Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574)
Salem, Virginia
October 6, 2022
Page 2 of 6
annual chance flood (or 100-year flood) as taken from the FIS is approximately 32,100 cubic feet second.
See “Table 4 - Summary of Discharges” from the Flood Insurance Study (FIS) contained in Appendix C.
Vertical Datum – it is noted that the base flood elevations and all elevations expressed in the FIS and on
the FIRM’s are based on North American Vertical Datum (NAVD) of 1988.
Existing Bridge Geometry:
The existing Apperson Drive Bridge over the Roanoke River is a two-span structure with an overall length
of approximately 155-feet and a width of 53-feet. The pier is located near the mid-point of the span.
The abutments and pier are cast-in-place concrete gravity structures with spread footings.
The bridge deck elevations, height of parapet wall & rail, and low-chord elevations are all available from
the detailed field survey and will be used in the modeling of the new bridge. Based on the survey
information, the total structure depth (distance from low chord to top of parapet wall) is estimated as
+/- 8.0-feet. Key elevations obtained from the survey and portions of existing bridge plans that were
used in the hydraulic analysis are shown in Appendix D.
Proposed Bridge Geometry:
The design of the bridge replacement calls for a typical section that consists of an 11’ shared use path on
the downstream (south) side of the bridge, five (5) 11’-0” wide lanes, and shoulder widths of 3’-0” each.
The overall width of the replacement bridge is 75’-6” – 22.5-feet wider than the original.
The design leaves the existing pier (single) and abutments in-place and widens the bridge by extending /
lengthening the piers and abutments. Due to restriction imposed by the street geometry and approach
alignments from the east, the bridge widening is proposed to occur mostly on the upstream (north) side
of the bridge, but some widening is also proposed on the downstream (south) side to accommodate the
new shared use path. The total structure depth (distance from low chord to top of railing) proposed is
7.31-feet – 0.69-feet shallower than the original bridge. The approach roadway elevation remain
generally unchanged. While not the most important component for the hydraulic analysis of a bridge,
the hydraulic opening for the existing and replaced structure remain approximately the same at +/-
2,223 SF.
Relevant bridge details are included in Appendix E.
Regulatory Requirements:
Salem City Code Sec. 106-226. - Floodplain Overlay District (FOD) addresses the regulatory requirements
for development within the floodplain and floodway. A copy of the Code is provided for reference in
Appendix E.
Relevant section of the Code are: 106-226.6(E) and 106-226.7(A). The critical text from these sections
are provided below.

106-226.6(E): Streets and sidewalks. Streets and sidewalks in all floodplain districts shall be designed to
minimize their potential for increasing and aggravating the levels of flood flow. Drainage openings shall
be required to minimize flood flows without significantly increasing flood heights or established
elevations identified floodplain districts.
106-226.7(A): Generally. Under no circumstances shall any use, activity, stream bed alteration or
relocation, new construction, substantial improvements and/or development adversely affect the
capacity of the channels or floodways of any watercourse, drainage ditch or any other drainage facility
or system. In floodways, no encroachments, fill, new construction, substantial improvements or other
development shall be permitted, except where the effect of such development (as may be permitted in
accordance with the regulations of the underlying zoning district) on flood heights is fully offset by
accompanying improvements which have been approved by appropriate local, state and/or federal
authorities as required by law (i.e., no proposed use, development or activity shall be permitted within
the floodway which would cause any increase in flood levels during the 100-year flood).
It is understood that the existing and proposed bridge abutments, associated walls/wing wall, and piers
are not classified as “structures” by the Zoning Code; however, any fill placed in the floodway, as well as
the conveyance displacements caused by structural components to support the bridge components
(e.g. abutments, piers, etc.) would be evaluated against these requirements.
Additional relevant regulatory guidance provided by FEMA states that in areas where there is incidental
filling within the floodway, no impacts are deemed to occur if there is a balancing of the cut / fill within
the floodway in the general vicinity of the area of fill (e.g. 200-feet upstream and 200-feet downstream).
That is to say, there must be an equal or greater amount of cut in the floodway immediately adjacent to
any proposed fill area. We understand that this guidance is usually only applied to incidental fill and may
not be utilized for bridge and structure components.
If the above criteria can be met, it is assumed that only local (i.e. City of Salem) approval is required and
a Conditional Letter of Map Revision (CLOMR) will not be required. It is unclear if approval by the City’s
Board of Zoning Appeals (as permitted by Sec. 106-226.9) is required.
Hydraulic Analysis/Modeling:
The hydraulic model used for this analysis was provided by Flood Plain Management Services Section /
Water Resources Division / U.S. Army Corps of Engineers, Norfolk District through a request submitted
to Federal Emergency Management Agency (FEMA). The model was developed by FEMA Contractor and
the U.S. Army Corps of Engineers under the most recent Roanoke River Re-study initiative. The hydraulic
model was provided in Hydrologic Engineering Center - River Analysis System (HEC-RAS) format and will
be executed under Version 4.1.0 of the software.
Existing Conditions Model: The model provided covered a large reach of the Roanoke River through
Roanoke County and Roanoke City - from State Route 773 (Cannery Road) on the upstream reach to the
near the Blue Ridge Parkway on the downstream end. In order to make the model more manageable,
the reach geometry was truncated to cover the reach length from upstream of Colorado Street

(US Rte. 11) to downstream of Electric Road (US Rte. 419). The critical sections included in the truncated
model are:
Upstream Reach: R.S 1955848
Downstream Reach: R.S. 1945415
Colorado Street/U.S. Rte. 11 Bridge: 1953858
Apperson Drive / U.S. Rte. 11 Bridge: 1948697
Electric Road / U.S. Rte. 419 Bridge: 1946350
The existing Apperson Drive Bridge is located at River Station (R.S.) 1948697 and is bound on the
upstream by Cross Section (XS) 1948773 and on the downstream by XS 1948609. A cursory review of the
bridge geometry and relevant cross sections contained in the model generally appears to reflect
conditions from the design survey. This is to be expected since the Corps of Engineers performed LIDAR
mapping of the study area as part of the re-study.
Corrected Effective Model: In order to develop this model, the “Existing Conditions Model” was saved as
the “Corrected Effective Model” and the following steps were taken:
Simplify bridge geometry by deleting un-necessary data points. Model cross sections were
develop using LIDAR Survey TIN Data and included over 50 cross section data points across the
deck, and on the low and high chord. Since the new bridge will have a uniform slope, the section
was simplified to three data points, one at each abutment and one at the center pier.
Adjust low-chord elevations at both abutments and center pier to match field survey:
o Upstream:
Abutment A = 989.86
Pier = 990.68
Abutment B = 991.52
o Downstream:
Abutment A = 989.94
Pier = 990.67
Abutment B = 991.64
Check and adjust parapet height on bridge to match survey data.
Refer to Appendix D – Existing Bridge Survey Data
Proposed Conditions Model: In order to develop the proposed conditions model, the “Corrected
Effective Model” was saved as the “Proposed Conditions Model” and the following steps were taken:
Change bridge width from 52.9-feet to 74-feet.
Change position of bridge relative to upstream cross section 1948773) and
downstream section (1948609) to account for new width.
Low-chord elevations were unchanged as existing abutment seat and pier seat
elevations were unchanged.
Change/update high-chord elevations to reflect new parapet/barrier.

The bridge deck and roadway geometry was unchanged.
Upon developing the Proposed Conditions Geometry, the model was run and the results compared to
the “Corrected Effective Conditions Model.”
Discussion of Modeling Results:
The hydraulic models were compiled and run within HEC-RAS. The results indicates that when compared
to the “Corrected Effective Model” the “Proposed Conditions Model” results in a +/- 0.00-foot change in
computed water surface elevation for the 1-Percent Annual Chance Flood. The results are tabulated
below.

The detailed results are summarized in Output Table contained as Appendix G.
A review of the preliminary plans indicated that no fill is proposed within the Floodway. Based on these
preliminary results it appears that the project meets the City’s regulatory requirements related to
floodplain/floodway.
Preliminary Scour Analysis:
The HEC-RAS Model was utilized to perform a basic analysis of scour potential at the piers and at the
abutments. The scour analysis computed both long-term contraction scour and localized pier scour.
The soil parameters used in the scour analysis were taken from the report and analysis entitled
“Geotechnical Engineering Report - Apperson Drive over Roanoke River” as prepared by ECS Mid-
Atlantic, LLC.
The results of the scour analysis indicate that the total unprotected scour depth (abutment, pier, and
contraction) ranges from 1.2 to 6.18-feet. The summary results are presented in Appendix H.
Abutment Foundations: The abutments will be supported by a spread footing which will bear directly on
sub-soil foundations. The elevation of the footings are shown on Sheets B-8 through B-11. Based on a
review of the elevations, the bottom of footing for Abutment A is situated at elevation +/- 974.6, which

is +/- 8.3-feet below finished grade, and the bottom of footing for Abutment B is situated at elevation
+/- 973.3, which is +/- 8.1-feet below finished grade. Both abutment footings appear to be founded well
below the computed scour depth.
Pier: The center pier will be supported by a spread footing which will bear directly on sub-soil
foundations. The elevation of the footing is shown on Sheets B-14. Based on a review of the elevations,
the bottom of footing for the center pier situated at elevation +/- 969.3. The computed scour
depth/elevation at the center pier is +/- 696.5.
The geometry and elevation of the abutments and pier footing are such that the bridge foundations will
bear on rock formations or hard shale that has been determined to resist scour within the service life of
the bridge. Additional counter-measures will include placement of Class II riprap armor stone at a depth
of 38-inches along the face of the abutments.

Appendix E –City of Salem Code / Sec. 106-226. – Floodplain Overlay District (FOD) (7 Pages)
Sec. 106-226. Floodplain overlay district (FOD).
Sec. 106-226.1. Statement of intent.
(A) It is the intent of the Floodplain Overlay District to aid in providing safety and protection from flooding. More
specifically, the standards contained in this district help to prevent the creation of health and safety hazards,
the loss of property and life, the disruption of commerce and governmental services, the extraordinary and
unnecessary expenditure of public funds for flood protection and relief, and the impairment of the tax base
by:
1. Restricting the unwise use, development and occupancy of lands subject to inundation which may
result in soil erosion, sedimentation and siltation, pollution of water resources, and general
degradation of the natural and manmade environment;
2. Regulating uses, activities and development which, acting alone or in combination with other existing
or future uses, activities and development, if unregulated, will cause unacceptable increases in flood
heights, velocities and frequencies;
3. Restricting or prohibiting certain uses, activities and development from locating within areas subject to
flooding;
4. Requiring all those uses, activities and developments that do occur in flood prone area to be protected
and/or flood proofed against flooding and flood damage;
5. Protecting individuals from buying lands and structures which are unsuited for intended purposes
because of flood hazards; and
6. Adequately providing for qualification and continuation of the City of Salem in the regular program of
the national flood insurance program as administered by the Federal Emergency Management Agency.
(Ord. of 3-14-05(2))
Sec. 106-226.2. Definitions.
(A) All definitions pertaining to the administration and enforcement of the Floodplain Overlay District are found
in Article VI Definitions and Use Types.
(Ord. of 3-14-05(2))
Sec. 106-226.3. Administration and applicability.
(A) The provisions codified in this section shall apply to all lands within the jurisdiction of the City of Salem
identified as being floodplain districts as stipulated in this section. No land shall be developed and no
development and/or structure shall be located, related, constructed, reconstructed, enlarged or structurally
altered except in full compliance with the terms and provisions of this district and any other applicable
ordinances and regulations which apply to uses within the jurisdiction of this chapter.
(Ord. of 3-14-05(2))
Sec. 106-226.4. Establishment of floodplain districts and restrictions.
(A) Floodplain districts shall include all land subject to inundation by the waters of the 100-year flood. The
source of this delineation shall be the flood insurance study for the City of Salem, as prepared by the Federal
Created: 2022-03-01 14:08:38 [EST]
(Supp. No. 22)
Insurance Administration-Federal Emergency Management Agency, dated, September 28, 2007, or the most
recent revision thereof. The designated floodplain districts and accompanying regulations shall be overlays to
the existing underlying zoning districts as shown on the official zoning map, and as such the provisions for
floodplain districts shall serve as a supplement to the underlying zoning district regulations. The physical
boundaries of the floodplain districts are established as shown on the flood insurance rate map (FIRM) from
the above-cited flood insurance study, which map is declared to be a part of this ordinance and which shall
be kept on file in the office of the Building Official and the Clerk of Council. In the event of any conflict
between the provisions of the overlaying floodplain districts and the underlying existing zoning regulations,
the more restrictive provisions shall apply.
(B) The delineation of any floodplain district may be revised, amended and modified by the Council after
Planning Commission and Council public hearings as required by section 106-520 of this Code and, § 15.2-
2204 of the Code of Virginia, in compliance with the national flood insurance program, when there are
changes through natural, man-made or other causes and/or changes are indicated by future detailed
hydrologic and hydraulic studies. All such changes are subject to the review and approval of the Federal
Emergency Management Agency.
Initial interpretations of the boundaries of the floodplain districts shall be made by the building official.
Should a dispute arise concerning the boundaries of any of the areas, the Board of Zoning appeals, in accordance
with section 106-528 shall make the necessary determination. Persons questioning or contesting the location of
the flood boundary shall be given a reasonable opportunity to present their case to the Board and to submit
technical evidence.
(C) All applications for development in the floodplain district and all permits issued for the floodplain shall
incorporate the following information.
1. For structures to be elevated, the elevation of the lowest floor (including basement).
2. For structures to be flood proofed (nonresidential only), the elevation to which the structure will be
flood proofed.
3. The elevation of the 100-year flood.
4. Topographic information showing existing and proposed ground elevations.
(Ord. of 3-14-05(2); Ord. of 9-10-07)
Sec. 106-226.5. Development and use by certificate of elevation.
(A) All uses, activities, development, new construction and substantial improvements, including prefabricated
buildings and manufactured homes, occurring within any floodplain district shall be undertaken only upon
the issuance of a certificate of elevation and shall be undertaken only in strict compliance with the provisions
of this chapter and with all other applicable codes and ordinances, including the City of Salem's subdivision
regulations. Prior to the issuance of any permits, the building official shall require all applications to include
compliance with all applicable state and federal laws.
(Ord. of 3-14-05(2); Ord. of 12-12-05(4))
Sec. 106-226.6. Development regulations, all districts.
(A)Generally. In any floodplain overlay district, the development and/or use of land (including new construction
and substantial improvements, placement of manufactured home and prefabricated buildings) shall be
permitted in accordance with the regulations of the underlying district, provided that all such uses, activities
and/or development shall be undertaken in strict compliance with flood proofing, elevation, anchorage and
related provisions contained in the Virginia Uniform Statewide Building Code and all other applicable codes
Created: 2022-03-01 14:08:38 [EST]
(Supp. No. 22)
and ordinances, and shall be constructed with material and utility equipment resistant to flood damage, and
be constructed by methods and practices that minimize flood damage.
The lowest floor elevation of any new residential structure constructed within a floodplain shall be at least
one foot above base flood elevation. The lowest floor elevation of any new non-residential structure shall also be
one foot above base flood elevation, unless such structure is floodproofed. No existing structure shall be modified,
expanded, or enlarged unless the new construction complies with this standard.
(B)Electrical and plumbing improvements. All electrical water heaters, electric furnaces, other critical electrical
installations and all other electrical, heating, ventilation, plumbing and air condition equipment shall be
permitted only at elevations at or above the level of the 100-year flood in all floodplain districts, or shall be
so designed or located such that waters from the base flood cannot enter or accumulate within any
components.
(C)Telephone utilities. All telephone utilities to be placed in any floodplain district shall be located and
constructed to minimize the chance of impairment during a flood, including being elevated above the level of
the 100-year flood whenever possible.
(D)Water, sewer, gas, oil facilities. New and replacement water supply systems, sanitary sewage systems
including pumping stations and collector systems, and gas and oil supply systems shall be designed and
located to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems
into floodwaters in all floodplain districts.
(E)Streets and sidewalks. Streets and sidewalks in all floodplain districts shall be designed to minimize their
potential for increasing and aggravating the levels of flood flow. Drainage openings shall be required to
minimize flood flows without significantly increasing flood heights or established elevations identified
floodplain districts.
(F)Drainage. Adequate drainage shall be provided to minimize exposure to flood hazards in all floodplain
districts and be designed to convey the flow of surface waters without damage to persons or property. The
system shall ensure drainage away from buildings, onsite waste disposal sites and septic tank facilities with
subsurface disposal fields. The city may requires a primarily underground system to accommodate frequent
floods and a secondary surface system to accommodate larger, less frequent floods. Drainage plans shall be
consistent with local, regional and state drainage plans and requirements. All facilities shall be designed to
prevent the discharge of runoff onto adjacent properties.
(G)Land subdivisions and new developments. The preliminary subdivision plat requirements contained in the
Salem Subdivision Ordinance shall include a map showing the location of the proposed subdivision and/or
land development with respect to any designated flood, including information on but not limited to, the 100-
year flood elevations, boundaries of the floodplain districts, proposed lots and sites, fills and flood or erosion
protective facilities. Proposals for any other new development shall also include base flood elevation data
and location of any floodplain districts. Subdivision proposals and other proposed new development,
including manufactured home parks and subdivisions, shall be reviewed to determine whether such
proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new
development is in a flood prone area, any such proposals shall be reviewed to assure that:
1. All such proposals are consistent with the need to minimize flood damage within the flood prone area;
2. All public utilities and facilities, such as sewer, gas, electrical and water systems, are located and
constructed to minimize or eliminate flood damage; and
3. Adequate drainage is provided to reduce exposure to flood hazards.
(H)Manufactured homes. All manufactured homes to be placed or substantially improved within any floodplain
district shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is
at least one foot above the base flood elevation and is securely anchored to an adequately anchored
foundation system in accordance with the provisions of the Virginia Uniform Statewide Building Code. The
provision shall apply to subdivisions and lots where an existing manufactured home is replaced, any
Created: 2022-03-01 14:08:38 [EST]
(Supp. No. 22)
expansion to an existing park or subdivision, an existing manufactured home park or subdivision on which a
manufactured home has incurred substantial damage as the result of a flood, and to new parks, subdivisions
and installation constructed after the effective date of the initial floodplain regulations.
(I)Recreational vehicles. Recreational vehicles placed on sites shall either:
1. Be on the site for fewer than 180 consecutive days; and,
2. Be fully licensed and ready for highway use; or
3. Meet the permit requirements for placement in the elevation and anchoring requirements for
manufactured homes in accordance with the provisions of this chapter.
(J)Area below lowest floor. For all new construction and substantial improvements, fully enclosed areas below
the lowest floor that are subject to flooding shall be designed to automatically equalize hydrostatic flood
forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this
requirement must either be certified by a registered professional engineer or architect or must meet or
exceed the following minimum criteria: A minimum of two openings, having a total net area of not less than
one square.
(Ord. of 3-14-05(2))
Sec. 106-226.7. Development restrictions, floodway.
(A)Generally. Under no circumstances shall any use, activity, stream bed alteration or relocation, new
construction, substantial improvements and/or development adversely affect the capacity of the channels or
floodways of any watercourse, drainage ditch or any other drainage facility or system. In floodways, no
encroachments, fill, new construction, substantial improvements or other development shall be permitted,
except where the effect of such development (as may be permitted in accordance with the regulations of the
underlying zoning district) on flood heights is fully offset by accompanying improvements which have been
approved by appropriate local, state and/or federal authorities as required by law (i.e., no proposed use,
development or activity shall be permitted within the floodway which would cause any increase in flood
levels during the 100-year flood).
(B)Alternation and relocation of floodway and channel. Prior to any proposed alteration or relocation of any
channels or floodways of any watercourse, stream, etc., within the City of Salem, approval shall be obtained
from the U. S. Corps of Engineers, the State Water Control Board and the State Marine Resources
Commission. Furthermore, notification of the proposal shall be given by the applicant to all affected adjacent
jurisdictions, the Department of Conservation and Recreation (Division of Dam Safety and Floodplain
Management) and the Federal Insurance Administration.
(C)Manufactured homes. The placement of any manufactured home within any floodway is strictly prohibited
except in an existing manufactured home park or existing manufactured home subdivision.
Manufactured homes that are not subject to the provisions of this ordinance shall be elevated so that either:
(1) the lowest floor of the manufactured home is at least one foot above the base flood elevation; or (2) the
manufactured home chassis is supported by reinforced piers or other foundation elements of at least equivalent
strength that are no less than 36 inches in height above grade and be securely anchored to an adequately
anchored foundation system to resist flotation, collapse and lateral movement.
(Ord. of 3-14-05(2); Ord. of 9-10-07)
Sec. 106-226.8. Existing structures and vacant land.
(A) A structure or use of a structure or premises which lawfully existed before the enactment of this chapter but
which is not in conformity with the provisions of in this section may be continued in accordance with the
Created: 2022-03-01 14:08:38 [EST]
(Supp. No. 22)
provisions of this chapter. In addition, such structure or use shall be subject to the following additional
requirements:
1. Existing structures and/or uses located in floodways shall not be expanded or enlarged, unless the
effect of the proposed expansion or enlargement on flood heights is fully offset by accompanying
improvements.
2. Any modification, alteration, repair, reconstruction or improvement of any kind to a structure and/or
use located in any floodplain overlay district, to an extent or amount of less than 50 percent of its
market value, shall be elevated and/or flood proofed to the greatest extent possible.
3. The modification, alteration, repair, reconstruction or improvement of any kind to a structure and/or
use regardless of its location in the flood plain district to an extent or amount of 50 percent or more of
its market value shall only be undertaken in full compliance with the provisions of the Virginia Uniform
Statewide Building Code.
4. The owner and/or agents of any existing structure and/or use located in any flood plain overlay
districts shall fully disclose in writing to all prospective interested parties including, but not limited to,
purchasers and renters that (1) the land and/or structures are located in flood prone areas, and (2)
whether any variances have been granted for certain structures located in flood prone areas.
(Ord. of 3-14-05(2); Ord. of 9-10-07)
Sec. 106-226.9. Variances.
(A) The Board of Zoning Appeals, in accordance with section 106-528, may consider petitions for variance(s)
from the provisions of this chapter; provided, however, that all relevant factors pertaining to the danger to
life and property caused by increased flood levels and velocities due to encroachments are thoroughly
examined. In considering applications for variances, the Board shall consider the following factors:
1. The danger to life and property due to increased flood heights or velocities caused by encroachments.
2. The danger that materials may be swept onto other lands or downstream to the injury of others.
3. The proposed water supply and sanitation systems and the ability of these systems to prevent disease,
contamination and unsanitary conditions.
4. The susceptibility of the proposed facility and its contents to flood damage and the effect of such
damage on the individual owners.
5. The important of the services provided by the proposed facility to the community.
6. The requirements of the facility for a waterfront location and a location within a floodplain district.
7. The availability of alternate locations not subject to flooding for the proposed use.
8. The compatibility of the proposed use with existing development anticipated in the foreseeable future.
9. The relationship of the proposed use to the comprehensive plan and floodplain management program
for the area.
10. The safety access to the property by ordinary and emergency vehicles in times of flood.
11. The expected heights, velocity, duration, rate of rise and sediment transport of the floodwaters
expected at the site.
12. Such other factors which are relevant to the purposes of this division.
(B) No variance shall be granted for any proposed use, development or activity within any floodway district,
except in full compliance with all of the following requirements:

(Supp. No. 22)
1. The variance will not cause any increase in flood levels during the 100-year flood. (Appropriate
documentation from a registered engineer must be submitted which substantiates the impact on flood
heights, velocities and flows through hydrologic and hydraulic analyses and calculations.) If the
variance involves any alterations or relations to a floodway or its channel, such alterations or
relocations shall also be approved as required by law.
(C) The Board of Zoning Appeals shall notify the applicant for a variance(s) in writing that the issuance of a
variance(s) to construct a structure below the 100-year flood elevation:
1. Increases the risks to life and property; and
2. Will result in increased premium rates for flood insurance.
(A) A record of the notification, as well as all variance actions, including justification for their
issuance, shall be maintained, and any variances which are issued shall be noted in the annual
report submitted as required by law.
(B) Variances may be issued for the reconstruction, rehabilitation or restoration of structure listed
on the National Register of Historic Places or the state landmarks register without regard to the
procedures set forth in this section.
(C) Requirements for granting a variance within the floodplain shall be as follows:
1. The failure to grant the variance would result in exceptional hardship to the applicant;
2. The variance will be the minimum relief to any hardship; and
3. The granting of such variance will not result in:
a. Unacceptable or prohibited increases in flood heights;
b. Additional threats to public safety;
c. Nuisances;
d. Fraud or victimization of the public; or
e. Conflicts with local laws or ordinances.
4. The applicant has shown a good and sufficient cause to justify the variance.

Sec. 106-226.10. Municipal liability.
(A) The degrees of flood protection sought by the provisions of this division is considered reasonable for
regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur on
rare occasions. Flood heights may be increased by manmade or natural causes, such as ice jams and bridge
openings restricted by debris. These provisions do not imply that areas outside the floodplain districts, or
that land uses permitted within such districts, will be free from flooding or flood damages.
(B) The provisions of this division shall not create liability on the part of the city or any office or employee
thereof for any flood damages that result from reliance on this division or any administrative decision
lawfully made thereunder.
