Any public road, private road, or driveway crossing a Special Flood Hazard Area shall require a `No-Impact' certification approval from the North Carolina Emergency Management Division before any building permits for new construction can be issued, which derive their vehicular access from such public roads, private roads, or driveways. If the "No-Rise " cert~cation data demonstrate that the Base Flood Elevation will rise more than one vertical foot, then the developer shall file a Conditional Letter of Map Revision with the North Carolina Division of Emergency Management for review and approval. Before any building permit can be issued for the improvements associated with the stream crossing, an approved Letter of Map Revision shall be on file in the Planning and Inspections Department. taf ~i.::, r _....~: 5. Recreational Vehicles. dewy e~ext~y-~t#~c~ie~di#}e~-Recreation vehicles placed on sites within a SFHA shall either: a. Be on site for fewer than 180 consecutive days and be fully licensed and ready for highway use (a recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick disconnect type utilities, and has no permanently attached additions); or (5) b. Meet all the requirements for new construction, including anchoring and elevation requirements of Section 42-68 and 42-91 and subsection (3) of this section. 09/26/2005 33 6. Elevated Buildings. New construction or substantial improvements of elevated buildings that include fully enclosed azeas that are below the regulatory flood protection elevation shall not be designed to be used for human habitation, but shall be designated to be used only for parking of vehicles, building access, or limited storage of maintenance equipment used in connection with the premises, be constructed entirely of jlood resistant materials below the regulatory flood protection level in A, AO, and AE, zones and meet the following design criteria , a. Measures for complying with this requirement shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. To meet this requirement, the foundation must either be certified by a North Carolina licensed Professional Engineer or Architect or meet the following minimum design criteria: Provide a minimum of two openings on different sides of each enclosed area subject to flooding; ii. The total net azea of all openings must be at least one (1) square inch for each square foot of enclosed area subject to flooding; iii. If a building has more than one enclosed area, each area must have openings on exterior walls to allow floodwaters to directly enter and exit; (5) iv. The bottom of all required openings shall be no higher than one (1) foot above the adjacent grade; v. Openings may be equipped with screens, louvers, or other opening coverings or devices provided they permit the automatic flow of floodwaters in both directions; and vi. Foundation enclosures made of flexible vinyl or sheet metal skirting are not considered enclosures for regulatory and flood insurance rating purposes, and therefore, do not require openings. Masonry or wood underpinning, regardless of structural status, is considered an enclosure and requires hydrostatic openings as outlined above to comply with this Ordinance. b. The enclosed areas shall be used solely for parking of vehicles, building access, or storage._Access to the enclosed area shall be the minimum necessary to allow for pazking of vehicles (gazage door) or limited storage of maintenance equipment used in connection with the premises (standard exterior door) or entry to the living azea (stairway or elevator). The interior portion of such enclosed area shall not be partitioned or finished into separate rooms, °,>wY~ <~ °~~'~ ° ~+°r V V11V1VJV JLV34b4.+~~J. (6) 09/26/2005 34 7. Temporary structures.

All service facilities such as electrical and heating equipment, shall be installed according to Section 42-91; a~ f. Openings to relieve hydrostatic pressure during a flood shall be provided belaw conforming to subsection (5) of this section; g. An accessory structure with any dimension that is twelve feet or less in height, width, or depth does not require an elevation or flood proofing certificate. Elevation or flood (5) 09262005 35 proofrng certifications are required for all other accessory structures according to Section 42-68(3); and h. The accessory structure shall meet all zoning and building code requirements. 9. Additions/Improvements. a. Additions and/or improvements to pre-FIRM structures whereas the addition and/or improvements in combination with any interior modifications to the existing structure are: i. Not a substantial improvement as defined and does not require a zoning or building ($) permit; the addition and/or improvements n shall be designed to minimise flood damages and shall not be any more non-conforming than the existing structure. ii. Are substantial improvement-s as defined requiring a zoning or building permit, both the existing structure and the addition and/or improvements shall comply with ' the standards for new construction. b. Additions to post-FIRM structures with no modifications to the existing structure shall require only the addition to comply with the standards for new construction. c. Additions and/or improvements to post-F1RM structures whereas the addition and/or improvements in combination with any interior modifications to the existing structure are: i. Not a substantial improvement, the addition and/or improvements only must comply with the standards for new construction; and, ii. ~A substantial improvement, both the existing structure and the addition and/or improvements must comply with the standards for new construction. (~ d. Where a fire wall or independent perimeter load-bearing wall is provided between the addition and the existing building, the addition(s) shall be considered a separate building and only the addition need comply with the standards for new construction.

Floodway and non-encroachment areas. Areas designated as floodways or non-encroachment areas are located within the SFHA established in Section 42-37. The floodways and non-encroachment areas are extremely hazardous areas due to the velocity of jloodwaters that have erosion potential and carry debris and potential projectiles. The following provisions shall apply to all development within such areas: 1: No encroachments, including fill, new construction, substantial improvements and other (5) developments shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses, performed according to standard engineering practice, that the proposed encroachment would not result in any increase. in the flood levels during the occurrence of the base flood. Such certification and technical data shall be presented to the Floodplain Administrator before issuance of jloodplain development permit. 2. If the requirements of Section 42-94b(1) are adhered to, all development shall comply with all applicable flood hazard reduction provisions of this Ordinance. 3. No manufactured homes shall be permitted, except replacement manufactured homes in an existing manufactured home park or subdivision, provided the following provisions are met: a.

These areas have special flood hazards associated with base flood depths of one (1) to three (3) feet where. a cleazly defined channel does not exist and where the path of flooding is unpredictable and indeterminate. The following provisions shall apply within such azeas: 1. All new construction and substantial improvements of all structures shall have the lowest floor, including basement, elevated to the depth number specified on the FIRM, in feet, above the highest adjacent grade. If no depth number is specified, the lowest floor, including basement, shall be elevated at least two feet above regulatory flood protection elevation as defined for the SFHAs, where no BFE has been established. 2. All new construction and substantial improvements of non-residential structures shall have the option, in lieu of elevation, to be completely flood proofed together with attendant utilities and sanitary facilities to or above that level so that any space below that level is the watertight with walls substantially impermeable to the passage of water and with structural components having the capacity of resisting hydrostatic and hydrodynamic loads and effects of buoyancy.

OPENING REMARKS FROM THE CHAIR B. PUBLIC CHARGE The Chair dispensed with the reading of the public charge. Chair Carey called the meeting to order and recognized Chair of the Orange County Planning Board Jay Bryan. C. PUBLIC HEARING ITEM 1. Orange County Flood Damage Prevention Ordinance Amendments a. Amend the existing 1981 Flood Damage Prevention Ordinance according to Federal Emergency Management Agency (FEMA) Region IV suggestions and the new State of North Carolina model for non-coastal jurisdictions. b. Continue participation in the Community Rating System (CRS), which can moderate property insurance costs. c. Review Administrative Procedures for the issuance of development permits near floodplains. 41 Planning Director Craig Benedict said that this is the only formal public hearing item on the agenda. This is a standalone. ordinance. Orange County became a participating community in the National Flood Insurance Program in 1975 and entered the regular FEMA- NFIP on March 16, 1981. Anew series of maps has recently been published that show where the flood hazard areas have changed. Since 1994, the County has only permitted three structures within floodplains. The State made some recommendations that are part of this ordinance. He said that adopting this amended ordinance would improve the community insurance rating system. The recommendation is to close the public hearing and adopt the amended ordinance. There was no one signed up to speak to this ifem. Commissioner Jacobs made reference to page 27 and the list of chemical compounds. He asked if there were any petroleum products because he thought some plastics were made out of petroleum products. Craig Benedict said that some products made from petroleum have been converted before they get to the site. He said that they could elaborate on certain products. Commissioner Jacobs asked to differentiate between treated wood and wood that can be reused. Commissioner Jacobs made reference to page 28 and asked if the State requires the County to allow new construction in flood hazard areas. Craig Benedict said that, according to the State, development is allowed in the floodplain if there are certain precautions. The County can do an outright prohibition. Geof Gledhill said that there is an opportunity for hardships to be dealt with, and he could not think of a legal problem where the County could not prohibit new construction in flood prone areas. . Commissioner Jacobs asked about the Public Market House, which will be the Farmer's Market, and said that .part of it will encroach on the floodway. This would be in violation to what he just proposed. Craig Benedict said tha# there are definitions about livable areas, and this would not be classified as a livable area. Commissioner Jacobs said that he would be interested in having the Planning Board make a recommendation to the County Commissioners. Commissioner Gordon asked about page five and what is meant by "common usage.° Craig Benedict said that this is a catchall phrase suggested by the State. Commissioner Gordon would also like a recommendation from the Planning Board. A motion was made by Commissioner Jacobs, seconded by Commissioner Halkiotis to ask the Planning Board and staff to consider more closely the list of prohibited compounds and consider an outright ban on new primary construction in flood hazard areas. VOTE: UNANIMOUS Chair Carey asked that it be brought back no sooner than September 15t John Link asked for clarification on the terms flood prone and floodplain. Craig Benedict said that they are interchangeable. Commissioner Gordon said that there is the floodplain, then the flood fringe. Craig Benedict said that they would work on the definitions. 42 MINUUTES ORANGE COUNTY PLANNING BOARD JULY 13, 2005 REGULAR MEETING AGENDA ITEM #10: FLOODPLAIN MODEL ORDINANCE (INFORMATIONAL ITEM Staff will provide an introduction to the proposed ordinance. The Planning Board will discuss the proposed ordinance in detail at the August 3 meeting. Precentor: Glenn Bowles, Planner II Glenn Bowles: There was a Public Hearing last month at which the Board of County Commissioners requested that the Planning Board review the revised ordinance and make recommendations. The floodplain ordinance has not been revised since 1995. In the last 2 years, there has been a concerted effort on the part of the State to map and remap the floodplain azeas in the State, with most of the remapping related to the coastal areas. In 2004, there was focus on the Neuse. Last month we had a public meeting where we focused on the Cape Fear Basin. We ate also trying to get involved in the CRS program to .lower insurance premiums. Included in your agenda packet is a mocked-up Ordinance which shows the old verbiage versus the new verbiage, as well as a list of flood-prone properties. The attached handout shows that the land surface in the County has dipped about eight tenths of a foot since 1981-2004. Some of it was associated with global warming but most of the changes were due to updated technology. As you can see, only a minimal number of properties axe affected by the change. We will discuss the actual changes at the next meeting. Jay Bryan: Is there a way to highlight what is happening in layperson's language and what the effects of the regulatory actions are? Glenn Bowles: We can insert notes in the margin. The changes primarily bring references up to date. Jay Bryan: Is this a minimal set of standards that are based on the state standards? Glenn Bowles: Basically with a few exceptions. Jay Bryan: It would be helpful if you could highlight the policies and changes. Ted Triebel: Are we voting on this proposal next month? When can we expect the annotated copy? Craig Benedict: We can include annotations in the next packet. There won't be a vote. Craufurd Goodwin: I just got a letter from my insurance company suggesting I purchase flood insurance. Is that the most dangerous hazard we face? Glenn Bowles: At a recent training session I attended, we learned that the chances of your house boring down are five times greater than it being flooded. Everyone has fire insurance. There aze 3,200 properties in the County that have flood plains on them, and all but 85 have no structures specifically in the flood plain. Flooding issues aze different across the State; 95% of the problems are in the coastal azeas. 43 Hunter Schofield: Could you elaborate on the statement "building retrofit required". Glenn Bowles: For those houses in the floodplain areas, if improvements to existing structures are desired, they have to be brought up it to standard. It depends on the type of improvement. If the improvement is grater than 50% of the market value of the house, or the house is destroyed, the homeowners have to bring the structure up to standards, which is generally increasing the elevation. 44 • MINUTES ORANGE COUNTY PLANNING BOARD AUGUST 3, 2005 REGULAR MEETING AGENDA ITEM #7: FLOODPLAIN MODEL ORDINANCE (Discussion -and Recommendation Item) Staff will make a presentation regarding the proposed ordinance, and request comments and recommendation to the BOCC for approval Presenter: Glenn Bowles, Planner II Glenn Bowles: Hurricane Floyd spurred changes in many of the floodplain ordinances across the State. North Carolina was one of the first states that had authority from FEMA to map floodplains and come up with model floodplain ordinances that go over and above the basic FEMA regulations. Last May there were new floodplain maps presented for the Neuse. There was also a public meeting regarding the Cape Feaz Basin in June, which was a joint affair with the Town of Carrboro and Chapel Hill. While it may be an understatement to say that flooding in the County is not as lazge of an issue than it is in other places. That doesn't mean it isn't an issue. The State of North Carolina provided a model ordinance for non-coastal communities. The state passed a state flood law in 2000, and now they aze asking the communities to pass local ordinances. I am now a Certified Floodplain Manager. for the County. We mailed letters to individual households in the County whose homes were previously in the floodplain and now are out of the floodplain to inform them they may need to contact their insurance company to modify their policy, if desired. We also sent letters to the homes that were not previously in a floodplain, but are now. The old floodplain mapping showed about 80 houses in the floodplain, which is now down to 39. The maps were generally inaccurate, but the elevations which those floodplains were derived from were fairly accurate. There were approximately 25 houses that were built after the original floodplain regulations were passed, and now each one of those houses were not in the floodplain if based solely on the elevation at the ground. We are also looking at the Consumer .Rating System to reduce flood premiums for those people who have flood insurance. Renee Price-Saunders: ~ Some of the wording is confusing; maybe we could use `pre-F)'RM' or `pre-FEMA' instead of `existing'. There were several typos. When you mention the `flood zone', please indicate what they aze and what they mean. A couple of areas where there is floor area, you may want to put `livable floor azea' to be more specific. On the section on chemicals, it states the storage of any chemical -you can look under the kitchen sink to find chemicals. Glenn Bowles: We don't have that many houses in the affected area that could have that problem. We may want to suggest that people store their domestic chemicals in another place if your house is susceptible to flooding. Craufurd Goodwin: This is great work. History reinforces the flood plain areas, but we haven't had a tremendous storm. Could people be notified that they aze not guaranteed to not experience flooding? Reference should not exclude those houses in flood plain may still flood. Jeff Schmidt: Fran was a major storm. Jay Bryan: There is a reference made to that type of exclusion. Glenn Bowles: We can try to emphasize that point. 45 Brian Dobyns: At the last meeting, I asked about the wording generated by the County versus generated by Federal and State statutes. 'The only place I could find was Section 42-92 in the specific standards. Glenn Bowles: In #21 and #22, the suggestion of the Boazd was they wanted to prohibit development with this ordinance. There were 3 places to do that; residential, non-residential construction and manufactured homes. Brian Dobyns: That is a change as well. Glenn Bowles: At the Public Hearing we listed many excluded chemicals, and when we do that a problem arises. When you list 25 chemicals, you will always miss the 26~' chemical. On number 12 `x' it states it is also listed in the Clean Water Act which is constantly being amended. If it is on that list, you can't store it. If someone were storing that type of material outside the house, we would have something to say about that. Brian Dobyns: On freeboazd for residential construction, it is shown as 2 feet above the regulatory flood protection elevation. Is that• is County too? Glenn Bowles:. The Federal model suggests is no free boazd. You get points; your flood premium goes down dramatically, and if we get the CRS program, we will get additional points, by adopting a 2-foot freeboard standard. Brian Dobyns: Does that add to construction cost? Glenn Bowles: It would if that were the only regulation dealing with streams. Our current regulations basically incorporate this level of freeboard. Brian Dobyns: This is above and beyond our buffer regulations. Even if you have 2 feet of free board, because of our buffer requirements, most likely that you will not be impacted anyway. Glenn Bowles: Yes. We won't describe it that way, because we will deal with buffer regulations. Before the Board wanted no development in the floodplain at all; we were really just enforcing stream buffer regulations. The freeboard standard would only deal with the existing houses and construction. Brian Dobyns: These 37 homes will now have to go back either be increased in height or be grandfathered? Glenn Bowles: If they want a building permit to substantially change the house. If the upgrade were more than 50% of the value of the house, then they would have to bring it up to code. Brian Dobyns: Does that mean actually raising the floor level? Glenn Bowles: It could, but it is not the only solution. Even with the houses in the floodplain, the first floor elevation is at least at or above it. We may be dealing with things we may not be able to do anything except raise it. If they have flood insurance, there is an increased cost and compliance' clause, that you can use money from your insurance carrier to lift it up or move it, but that would be the last alternative. Brian Dobyns: How many homes will be applicable? 46 Glenn Bowles: I haven't looked at the ones in the floodplain. There may be a few. With the exception of Heritage Hills in Chapel Hill that was built in the 70's, people have been good about not building in the floodplain. Brian Dobyns: Is there a way that those people who might be burdened be provided with same additional leeway? Jay Bryan: They have the right to variance. Glenn Bowles: Yes. Also, FEMA does have grant programs available to relocate structures. They will buy the property and relocate it. Brian Dobyns: Can the County provide as much information as possible to these people so they will be prepared? Glenn Bowles: I suspect we will. At this point we have only notified people who have had a status change. . Brian Dobyns: -Are the manufactured home provisions County regulations? Are manufactured homes defined as pre-fab homes that are brought to the site? Glenn Bowles: They are brought on site `in total' as opposed to being brought on site in pieces. Brian Dobyns: A modular would be allowed? Glenn Bowles: No. A modular would not be allowed. That would be the same as a residential construction. Replacement manufactured homes would need to be elevated. Renee Price-Saunders: The disclaimer (42-41) is on page 10. Brian Dobyns: On page 18, why can't we do variance after the fact? Is what we are saying is that if you are ignorant and build a 12' x 16' structure in the floodplain, you could not apply for the variance because of your mistake? Glenn Bowles: You could still apply for the variance, but it would be difficult for the Board of Adjustment to grant the variance. Brian Dobyns: Is that something you see in other ordinances? Ted Triebel: I don't know. Brian Dobyns: There aie a lot of people who could build structures and be ignorant of where the floodplain line is. Especially long time landowners. I understand that anything that is over 12 by 12 has to have a building permit unless you are in farming. Can farmers in the potential areas be notified to check all future buildings to make sure they are not in the floodplains if they are over 12 by 12? That could possibly alleviate that concern. Robert Davis: Farmers still have to come to us for permits. They are only exempt from zoning. They often check with us before they build new structures. 47 Brian Dobyns: My understanding was that farm structures did not need a building permit. Glenn Bowles: If this is a critical issue, perhaps we could do some type of outreach to notify the farmers of the new regulations. Renee Price-Saunders: On page 2 it defines an accessory structure, it lists structures and goes to farms. This maybe too general, and you may want to be more specific. Glenn Bowles: We can make some changes as long as we don't make it less exacting. Renee Price-Saunders: We can make it more pertinent to rural areas. Craufurd Goodwin: Was it a misprint that lumber was listed under chemical compounds? Glenn Bowles: Lumber was on one of the original lists. Typically lumber is not a chemical compound. Jay Bryan: Treated lumber could be. Glenn Bowles: There are a number of commodity storage units in the floodplain as well, so we have to be careful how it's addressed. Especially with regard to junkyards. Jeffrey Schmitt: What is the basis that this will be released to the general public in a readable fashion? Will there be a general notice in the paper? Jay Bryan: Do you mean will there be an educational component after the ordinance is approved? You may want to identify particular people that might be affected. Glenn Bowles: We have already sent letters to two types of individuals affected by the change, but did not address the third type of homeowners who will continue to be in the floodplain. We have also run legal ads in the newspapers about the proposed regulation changes. Jeffrey Schmitt: I have property in the floodplain and had I not been at this meeting, I probably would not be aware of the changes. Glenn Bowles: There are 3,228 parcels that have some land in the floodplain. Mass mailings don't often generate interest either, but we could possibly use some other form. Jay Bryan: You may want to identify a communication process. Renee Price-Saunders: You could put it up in various County buildings. Craufurd Goodwin: Are individuals prohibited from storing items (i.e., piles of gravel, cement logs, bricks, etc.) that will disturb the natural flow of water)? Brian Dobyns: Such as the use of temporary storage. Glenn Bowles: There can be a new item to clarify this. Renee Price-Saunders: One concern you mentioned is the concern of downstream flow, but when the rivers swell, they go outward, not down or up. 48 Jay Bryan: On page 10, Section 42-41 (Warning and Disclaimer), I would suggest that be given more prominence. It should be highlighted. Maybe it could be moved to page 1 after Section 42- 31 (Statutory Authorization). Also, has the attorney seen Section 41 on page 18 "The request for a variance is not after-the-fact or for a situation of one's own making". Glenn Bowles: I have sent it to the County Attorney, but I'm not sure he has reviewed it. Jay Bryan: I am fine with it overall but I would want him to look at that particular section to see if it complies in general with variance laws. On page 19, number 5, who submits the written report? Glenn Bowles: The applicant. Jay Bryan: That should be stated in the sentence. Renee Price-Saunders: On page 5, Section 3, could the Historic Preservation Commission see the section on Historic structures? Glenn Bowles: Yes. Noah Ranells: Could the Planning Board members have a map of the County or a map that shows where the floodplain is? Glenn Bowles: What about a County map showing floodplains and parcels? Noah Ranells: Will that be available on GIS for public access? We need to m~ximi~P availability. Glenn Bowles: We will have township maps to review at the next meeting. The Current Planning website has floodplain information. We may be able to get the maps attached. Brian Dobyns: The definitions of floodplain, flood prone, flood zone, special flood hazard area and regulatory floodplain seem to be similar and some seem to overlap. Are they all the same? Glenn Bowles: Yes. Flood prone is anything that might flood. The regulatory flood element issue is a defined elevation. Everything below that is flood prone. Every definition reflects an aspect of flooding. They are similar, but the defmitions and terms come from FEMA. Brian Dobyns: It would be helpful to know these terms are similar. The data .shows different terms. Craufurd Goodwin: Would you like a glossary? Brian Dobyns: Something that would make it clearer. Glenn Bowles: I will try to put a linkage to those terms. Noah Ranells: On page 2, under Accessory Structure, the fourth line states "the like"; there should be examples to explain that term. On page 6, at the bottom of the page, "Post-FIRM and 49 Pre-FIRM" should be clarified more. On page 7, under Riverine, eliminate the word etc. and use more examples or similaz things, On page 18, section 22-71, the wording needs to be changed. Jay Bryan: We are being asked to make recommendations tonight. Would anyone care to make a recommendation? MOTION made by Craufvrd Goodwin for adoption with designated changes. Noah Ranells seconded. VOTE: Unanimous Jay Bryan: Could someone delineate these recommended changes? Glenn Bowles: We could have a new version available at the next meeting.
