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 3.

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 Absent: Derr, Eanes, Sellers 3.

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.

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.        Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  Page 2 of 12      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  Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  Page 3 of 12      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  Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  Page 4 of 12      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.    Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  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.   Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  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.  Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  Page 7 of 12      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  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  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.     Hydraulic Analysis of Proposed Bridges & Trail Fill Sections  West Roanoke River Greenway  Roanoke County / City of Salem, VA  July 16, 2019  Page 9 of 12      5. Summary of Results:  a.

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. Narrative of Floodplain/Floodway and Scour Analysis Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574) Salem, Virginia October 6, 2022 Page 3 of 6 106-226.6(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 Narrative of Floodplain/Floodway and Scour Analysis Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574) Salem, Virginia October 6, 2022 Page 4 of 6 (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. Narrative of Floodplain/Floodway and Scour Analysis Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574) Salem, Virginia October 6, 2022 Page 5 of 6 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.

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 Narrative of Floodplain/Floodway and Scour Analysis Apperson Drive over Roanoke River Bridge Replacement (UPC# 110574) Salem, Virginia October 6, 2022 Page 6 of 6 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.

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. 106-226.4. 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.

(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.

(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: Created: 2022-03-01 14:08:38 [EST] (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. (Ord. of 3-14-05(2)) Created: 2022-03-01 14:08:38 [EST] (Supp. No. 22) 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.
