These revisions are similar to changes recently approved by the city of Cedar Falls. The revisions to Iowa City's ordinance incorporate the following facts and observations: 1) Along the Iowa River, the flood maps accurately predict the reach of floods that have a 1 % chance of occurring in any given year (e.g. 1993 flood) and floods that have a 0.2% chance of occurring in any given year (e.g. 2008 flood). The actual flood of 2008 was only slightly less than what was predicted and mapped. 2) In 1993 and 2008, Iowa City experienced "100-year" and "500-year" flood events along the Iowa River, but not along Ralston, Willow, or Snyder creeks. The Iowa River is subject to regional rain events throughout central Iowa; our creeks will reach predicted flood heights during sustained local rainstorms. 3) The flood insurance study considers the capacities of the Hickory Hill detention, the Scott Boulevard detention, detention ponds along Willow Creek and Snyder Creek, and so flood profile predictions of the 1 % and 0.2% floods along these tributaries should be recognized as reliable. Mapping errors along Willow Creek are due to mis-alignment of the floodplains and when the alignment is adjusted, the map is a reliable visual tool. Other mapping errors are due to permitted activities where grading and filling occurred, but detailed topographical information was not submitted to FEMA for map revision. 4) Flood hazard areas should be recognized as such without relying on statistical abstractions. The terms "100 year" and "500 year" cause people to misinterpret the actual, annual risk of investing in a flood hazard area. For example, over the life of a 30-year mortgage, property in a "100-year" floodplain actually has a 26% chance of flooding.' While it is important and necessary to distinguish between the 1 % and 0.2% floods for precise applications, our efforts should reference "flood hazard areas" to convey the risk of building in any flood zone. 5) In addition to protecting structures and their inhabitants, floodplain management includes minimizing risk to emergency responders. Evacuating neighborhoods puts responders at risk, and the risks to these responders increase during more time-consuming tasks like evacuating hospitals, care facilities, and jails. Operations centers for emergency responders should be located out of flood hazard areas so that responders are able to mobilize during a flood, and 1 The "1 in 100" chance is only accurate for the first year — the risk of flooding increases over time. In a ten year period, there is a 10% chance of a flood occurring in the "100-year" flood hazard area. In a 30-year period, that likelihood increases to 26%. In a 50-year period, there is a 39% chance of flooding. Source: Floodplain Management Desk Reference. concentrated populations of persons with limited mobility should be located outside of flood hazard areas. The following changes are proposed: 14-9F Definitions 1. Remove references to "100-year" and "500-year" and instead use the expression Flood Hazard Area throughout this section. Note: the flood insurance rate maps will still distinguish between the two types of flood, using the designations "A" and "X", respectively. 2. Add a definition of Class 1 Critical Facilities as those structures and uses to which access must be maintained during a flood, like emergency operation centers, communication centers, and hospitals. It also includes those facilities that are difficult or time consuming to evacuate during a flood such as jails, nursing homes, and group homes for persons with limited mobility and/or life - sustaining medical equipment. 3. Add a definition of Critical Facilities as those structures and uses that must be protected from flood damage, but do not necessarily need to be accessible during a flood. Some Critical Facilities, like city halls, courts, schools, and museums, must resume their functions as soon as possible after a flood event. Other Critical Facilities, like water distribution and wastewater treatment facilities, are expected to remain functioning during a flood event. These types of Critical Facilities should be designed and located to minimize potential damage but may be located within a regulated floodplain (indeed, may be located in a floodplain out of necessity). 4. Incorporate "areas of shallow flooding" which are illustrated on the Flood Insurance Rate Map (Zone AH), but which to date have not been addressed in Iowa City's floodplain regulations. Iowa City has one area of shallow flooding, where Willow Creek flows across the airport. Shallow flooding differs from other types in that there is no no floodway, no predictable path of flooding, and a 1 % or greater chance of flooding in any given year. 14-5J Floodplain Management Standards 1. Expand floodplain building standards and elevation requirements beyond the 1% (100-year) to include the 0.2% (500-year) floodplain. New and substantially improved structures will need to be elevated or floodproofed to one foot above the 0.2% flood elevation profiled in the Flood Insurance Study. In areas of shallow flooding, new and substantially improved structures will need to be elevated or floodproofed to one foot above the elevation shown on the Flood Insurance Rate Map, 2. Add two items to factors of consideration for a variance: the risk to emergency responders during a flood; and the importance of preserving the availability of the services during a flood event. 3. Variances to the floodplain management standards currently require that a variance be granted only if "the situation is unique to the property in question and not shared by other landowners in the area, or due to general conditions in the neighborhood." For buildings in the floodplain, it is a standard that is impossible to meet. The amendment proposes to remove this requirement, while keeping the other tests intact.2 4. Prohibit the construction of Class 1 Critical Facilities within the regulated floodplain. 2 14-413-2A. Approval criteria: 1. The proposed variance will not threaten neighborhood integrity, nor have a substantially adverse affect on the use or value of other properties in the area adjacent to the property included in the variance; and 2. The proposed variance will be in harmony with the general purpose and intent of this Title and will not contravene the objectives of the Comprehensive Plan, as amended; and 3. The property in question cannot yield a reasonable return if required to comply with the requirements and standards specified in the Title; and 4. The hardship is not of the landowner's or applicant's own making or that of a predecessor in title. 2 Impacts Flood insurance is a federally -mandated requirement, and our local ordinances will not change this basic fact: flood insurance is required whenever a federally -insured loan is approved for a structure within the 1 % flood hazard area. The difference between regulating the 1 % and the 0.2% floods vary in the height and reach of expected flood events. Along the Iowa River and the main branch of Ralston Creek, the elevation difference between the two flood events ranges from one foot to 4'3". Along other tributaries to the Iowa River (Willow, South Branch Ralston, Clear, Snyder, and Rapid creeks), the differences are not as extreme. Existing residential structures would be required to elevate their lowest floor to one foot above the 0.2% floodplain (or shallow flood elevation) whenever one of three changes occur: 1) the original floor area is increased by 25% (this is a cumulative measure, beginning with the year of Iowa City's first flood insurance study — 1977); • it is important to note that 'floor area " is defined such that it includes the total area of all floors measured to the outside surface of exterior walls, and includes space in the basement, cellar, or attic, if that space is used for a principal or accessible use 2) a building permit is issued to repairs to a structure and the value of repairs is 50% (or more) of the structure's value before the damage occurred; • the damage does not have to be damage from a flood —it can be from any disaster (e.g. flood, fire, tornado) 3) a building permit is issued for improvements to a structure and the value of improvements is 50% (or more) of the structure's current value. Existing commercial structures, or structures with commercial uses on the ground floor and residential uses above, have the option of flood -proofing the building such that the finished floor on the lowest level is not one foot above the flood hazard elevation. This is accomplished by using flood -resistant materials like concrete; waterproof adhesives; pressure treated lumber; metal doors and window frames. Recommendation: Staff recommends that Articles 14-5J and 14-9F and be amended as indicated on the attached pages. Please note that new language proposed is underlined and language to be deleted is shown with a strike -through notation. ATTACHMENTS: 1. Proposed Approved by: Doug 14-413-2: VARIANCES: The board of adjustment is empowered to grant variances from the provisions of this title that will not be contrary to the public interest when, owing to unique circumstances or conditions, a literal interpretation of this title would deprive the applicant of rights commonly enjoyed by other properties in the zoning district under the terms of this title and would impose unnecessary and undue hardship on the applicant. To ensure that the spirit of this title is observed and substantial justice done, no variance to the strict application of any provision of this title shall be granted by the board unless the applicant demonstrates that all of the following approval criteria are met. The procedures for obtaining a variance are set forth in chapter 8, article C, "Board Of Adjustment Approval Procedures", of this title. A. Approval Criteria: 1. The proposed variance will not threaten neighborhood integrity, nor have a substantially adverse effect on the use or value of other properties in the area adjacent to the property included in the variance; and 2. The proposed variance will be in harmony with the general purpose and intent of this title and will not contravene the objectives of the comprehensive plan, as amended; and 3. The property in question cannot yield a reasonable return if required to comply with the requirements and standards specified in this title; and 4. The owner's situation is unique or peculiar to the property in question, and the situation is not shared with other landowners in the area nor due to general conditions in the neighborhood, except when a variance from a floodplain management standard is requested per 14-5J-9; and 5. The hardship is not of the landowner's or applicant's own making or that of a predecessor in title. B. Use Variance Prohibited: Under no circumstance may the board grant a variance that would allow a land use, other than those specifically allowed in the zoning district in which the subject property is located. C. Burden Of Proof: The applicant bears the burden of proof and must support each of the approval criteria by a preponderance of the evidence. D. Precedents: The granting of a variance is not grounds for granting other variances for the same or differing properties. (Ord. 05-4186, 12-15-2005) 14-813-5: FLOODPLAIN DEVELOPMENT PERMIT: A.

The building official shall not issue permits for variances, except as approved by the board of adjustment according to the approval criteria for such variances set forth in chapter 5, article J of this title. (Ord. 05-4186, 12-15-2005) Article F. Floodplain Management Definitions As used in Article 14-53, Floodplain Management Standards, the following definitions shall apply. The General Definitions contained in Article A of this Chapter shall apply to all terms used in Article 14-53 that are not defined below. 1% ANNUAL FLOOD EVENT: The predicted level of flooding with a one percent (1%) chance of being equaled or exceeded in any given Year (formerly known as the 100-year flood event). 0.2% ANNUAL FLOOD EVENT: The predicted level of flooding with a two -tenths (0.2%) chance of being equaled or exceeded in any given year (formerly known as the 500-year flood event). BASEMENT: Any enclosed area of a building that has its floor or lowest level below ground level (subgrade) on all sides (see definition of Lowest Floor). CLASS 1 CRITICAL FACILITIES: Facilities that must remain accessible during the 0.2% flood event because they are the base of operations for emergency responders, are particularly difficult to evacuate during a flood event, or facilities that provide services essential to the life, health, and safety of the community. Class 1 Critical Facilities include police and fire stations, emergency medical centers, communication centers, hospitals, Jails, nursing homes, and other residential uses for persons with limited mobility and/or dependency upon life -sustaining medical equipment. CRITICAL FACILITIES: Structures that store public records; museums and libraries; schools; and other buildings that store rare and/or valuable items and information that sustain the history and public records of a community. These structures are not expected to remain accessible or functioning during a flood event, though in many instances their functions must resume as soon as possible after a flood event. Critical Facilities also include public insfrastructure such as water distribution and wastewater treatment facilities which are expected to remain functioning during a flood event although they may be temporarily inaccessible or accessible only by watercraft during a flood event. DEVELOPMENT: Any human made change to improved or unimproved real estate, including, but not limited to, the placement of manufactured housing, buildings or other structures, mining, dredging, streambank erosion control measures, filling, grading, paving, excavation or drilling operations. FLOOD: A general and temporary condition of partial or complete inundation of normally dry land areas resulting from the overflow of streams or rivers or from the unusual and rapid runoff of surface waters from any source. FLOOD CONTROL STRUCTURAL WORKS: Barriers or storage areas constructed to control floodwater, modify or re -direct a channel. FLOOD ELEVATION: The elevation which floodwaters would reach at a particular site during the occurrence of a specific frequency flood. For instance, the 400- 1% flood elevation is the elevation of floodwaters with a 1% likelihood of occurring in any given year. The 0.2% flood elevation is the elevation of floodwaters with a 0.2% likelihood of occurring in any given year. In areas of shallow flooding, there is a 1% or greater annual chance of flooding to an elevation specified on the Flood Insurance Rate Map. FLOOD HAZARD AREA: Land that is shaded and identified as "AE", "X" or "AH" on the Flood Insurance Rate Man. FLOOD HAZARD ELEVATION: The elevation of the 0.2% flood as profiled in the Flood Insurance Study for Johnson County, Iowa. In areas of shallow flooding, the elevation of the flood as illustrated on the Flood Insurance Rate Map. FLOOD INSURANCE RATE MAP: The official map prepared as part of (but published separately from) the flood insurance study which delineates both the flood hazard areas and the risk premium zones applicable to the community. FLOOD INSURANCE STUDY: A study initiated, funded and published by the federal insurance administration for the purpose of evaluating, in detail, the existence and severity of flood hazards, providing the city with the necessary information for adopting a Floodplain management program and establishing actuarial flood insurance rates. FLOODPLAIN: Any land area susceptible to being inundated by water as a result of a specific frequency flood. FeF instaigee, For instance, the 1% floodplain is the area of land that, in any given year, has a 1% likelihood of flooding. The 0.2% floodplain is the area of land that, in any given year, has a 0.2% likelihood of flooding. In areas of shallow flooding there is a 1% or greater annual chance of flooding to a specified elevation, but a clearly defined channel does not exist, and the path of flooding is unpredictable. FLOODPLAIN MANAGEMENT: An overall program of corrective and preventive measures for reducing flood damages and for promoting the wise use of Floodplains, including, but not limited to, emergency preparedness plans, flood control works, floodproofing and Floodplain management regulations. FLOODPROOFING: Any combination of structural and nonstructural additions, changes or adjustments to structures, including utility and sanitary facilities, which will reduce or eliminate flood damage to such structures. FLOODWAY: The channel of a river or stream and those portions of the Floodplains adjoining the channel which are reasonably required to carry and discharge floodwaters so that confinement of floodwaters to the floodway area will not result in substantially higher flood elevation. Where floodway data has been provided in the flood insurance study, such data shall be used to define the floodway limits. Where no floodway data has been provided, the Iowa Department of Natural Resources or its suEEesse assignee shall be contacted to provide a floodway delineation. Where floodway data is not available, it shall be the responsibility of the permittee to produce engineered data delineating the floodway.. FLOODWAY FRINGE: Those portions of the Floodplain, other than the floodway, which can be filled, leveed or otherwise obstructed without causing substantially higher flood elevations. LOWEST FLOOR: The floor of the lowest enclosed area in a building, including a basement, except when all the following criteria are met: • The enclosed area is designed to flood to equalize hydrostatic pressure during floods with walls or openings that satisfy the provisions of 14-51-71) of this Title; and • The enclosed area is unfinished (not carpeted, drywalled, etc.) and used solely for low damage potential uses, such as building access, parking or storage; and • Machinery and service facilities (e.g. hot water heater, furnace, electrical service) contained in the enclosed area are located at least one foot above the 100-year flood elevation; and • The aFea floor is not below grade on all sides. MANUFACTURED HOUSING: Any structure designed for residential use which is wholly or in substantial part, made, fabricated, formed or assembled in manufacturing facilities for installation or assembly and installation on a building site. For the purposes of Article 14-53, Floodplain Management, manufactured housing includes factory built homes, mobile homes, manufactured homes and modular homes and also includes park trailers, travel trailers and other similar vehicles placed on a site for greater than 180 consecutive days. MANUFACTURED HOUSING PARK: A parcel or contiguous parcels of land divided into two or more manufactured housing lots for rent or sale. NEW CONSTRUCTION OF NEW BUILDINGS, MANUFACTURED HOUSING PARKS: Those structures or development that began construction after 3anuap� 1, 1.978. May 2, 1977. SHALLOW FLOOD HAZARD AREA: Areas of special flood hazards having shallow water depths and/or unpredictable flow oaths between one (1) and three (3) feet, and with water surface elevations determined. STRUCTURE: Anything constructed or installed on the ground or attached to the ground, including, but not limited to buildings, factories, sheds, cabins, manufactured housing, storage tanks and similar. SUBSTANTIAL DAMAGE: Damage of any origin sustained by a structure where the cost of restoring the structure to its pre -damaged condition would equal or exceed 50 percent of the assessed or market value as established by an appraisal paid for at the owner's expense. SUBSTANTIAL IMPROVEMENT: Any improvement to a structure that satisfies either of the following criteria: Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds fifty percent of the assessed or market value as established by an appraisal paid for at the owner's expense, of the structure either before the improvement or repair is started or, if the structure has been damaged and is being restored, before the damage occurred. For the purposes of this definition, substantial improvement is considered to occur when the first alteration of any wall, ceiling, floor or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure. The term does not, however, include any project for improvement of a structure to comply with existing state or local health, sanitary or safety code specifications which are solely necessary to assure safe conditions for the existing use. • Any addition which increases the original floor area of a building by 25 percent or more. All additions constructed after ,ig� May 2, 1977 shall be added to any proposed addition in determining whether the total increase in original floor space would exceed 25 percent. Article I Floodplain Management Standards The purpose of this Article is to protect and preserve the rights and privileges and property of Iowa City and its residents and to protect, preserve and improve the peace, safety, health, welfare, comfort and convenience of its residents by minimizing flood losses. The provisions of this Article are designed to: A. Reserve sufficient Floodplain area for the conveyance of flood flows so that flood heights and velocities will not be increased substantially. B. Restrict or prohibit uses that are dangerous to health, safety or property in times of flood or that cause excessive increases in flood heights or velocities. C. Require that uses vulnerable to floods, including public utilities that serve such uses, be protected against flood damage. D. Assure that eligibility is maintained for property owners to purchase flood insurance through the national flood insurance program. A. Application of Provisions The regulations within this article apply to all lands and uses that haVe SigRifiEaFl identified in the "Johnson County, Iowa, And Incorporated Areas Flood Insurance Rate Map", dated February 16, 2007. , shall be us The "Johnson County, Iowa and Incorporated Areas Flood Insurance Study", as amended, is hereby adopted by reference and is made a part of this article for the purpose of administering floodplain management regulations. B. Minimum Requirements The provisions of this Article are considered minimum requirements and will be liberally construed in favor of the governing body and will not be deemed a limitation or repeal of any other powers granted by State statutes. C. Abrogation and Greater Restrictions It is not intended by this Article to repeal, abrogate or impair any existing easements, covenants or deed restrictions. However, where this Article imposes greater restrictions, the provisions of this Article shall prevail. Where more specific provisions herein conflict with other provisions of this Title, this Article shall prevail. A. Legal Authority Chapter 455B, Code of Iowa, as amended, gives cities authority to adopt regulations governing development and redevelopment within flood hazard areas, including designation of flood hazard maps. B. Legislative Findings 1. The flood hazard areas of Iowa City are subject to periodic inundation which can result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief and impairment of the tax base, all of which adversely affect the peace, safety, health, welfare, comfort and convenience of its residents. 2. These flood losses, hazards, and related adverse effects are caused by the occupancy of flood hazard areas by uses vulnerable to flood damages. Such uses create hazardous conditions as a result of being inadequately elevated or otherwise protected from flooding and the cumulative effect of obstructions on the Floodplain causing increases in flood heights and velocities. 3. This Article relies upon engineering methodology for analyzing flood hazards, which is consistent with the standards established by the Iowa Department of Natural Resources or its sueeesser assignee. 14-57-4 Compliance with Provisions; Nonconforming Situations A. Except as provided in subsection B, below, no structure or land shall hereafter be used and no structure shall be located, enlarged, converted or structurally altered without full compliance with the terms of this Article. B. If a structure that is not in compliance with the provisions of this Article lawfully existed prior to May 2, 1977 and has existed continuously without abandonment since that time, then improvements may be made to the structure, notwithstanding the provisions of this Article, provided such improvements do not constitute a substantial improvement as defined in Article 14-9F, of this Title, Floodplain Management Definitions. However, structures, uses, or development that are nonconforming with regard to other provisions of this Title must comply with the applicable regulations contained in Article 14-4E, Nonconforming Situations. 14-53-5 Enforcement A. Enforcement Official Designated The Building Official shall administer and enforce the provisions of this Article. B. Duties and Responsibilities Duties and responsibilities of the Building Official include, but are not necessarily limited to the following: 1.

MINUTES PRELIMINARY PLANNING AND ZONING COMMISSION MAY 17, 2010 — 6:00 PM — INFORMAL LOBBY CONFERENCE ROOM, CITY HALL MEMBERS PRESENT: Ann Freerks, Elizabeth Koppes, Charlie Eastham, Wally Plahutnik, Michelle Payne MEMBERS ABSENT: Josh Busard, Tim Weitzel STAFF PRESENT: Bob Miklo, Karen Howard, Jacob Rosenberg, Sara Greenwood Hektoen, Kristin Watson OTHERS PRESENT: None CALL TO ORDER: The meeting was called to order at 6:00 p.m. by Chairperson Ann Freerks. ZONING CODE ITEMS: 1. Discussion of an amendment to the Zoning Code to allow more flexibility in the application of development standards as they apply to nonconforming developments. Howard said this is often the most difficult section of the code to understand. She said that because each property is different and years of development took place prior to the implementation of current code, it is difficult to write code so that it applies to every situation and yet is still reasonable. She said that if there was no nonconforming section of the zoning code then property owners would have to bring their whole properties into compliance whenever the code or use changed. She said the purpose of this section is to provide some relief for property owners as things change over time. Howard explained that the code had been liberalized in 2005 to allow for more outdoor storage; however, at that time screening standards for that outdoor storage were also put in place. Similarly, there was no screening of parking lots or required separation between the street and the parking area prior to the code changes. There was also no screening required for outdoor work areas. Howard said that one of the problems that has been experienced with the new code is that there is sometimes not enough space on the property to accommodate the required setbacks and screening. In those and similar cases, property owners began going through the minor modifications process to adjust things, which concerned the Building Official because that was not the original intent of the process. Howard said the idea has been to get the properties as close to compliance as possible, using the minor modification process as needed. Howard said that another problem with the way the code is currently written occurred when new uses came into large buildings like shopping malls. When a tenant with a new use came into a mall, the entire mall was required to come into compliance under the current code. Howard said this seemed like an unreasonable requirement. Planning and Zoning Commission May 17, 2010 - Informal Page 2of7 Howard addressed the specific proposed zoning amendments. She stated that properties that have been vacant for a year or more should be brought into compliance with the code. She said that for elements that simply could not be complied with due to site constraints, the property owner can apply for a minor modification to adjust or waive certain standards. Payne asked who would waive the requirement. Howard said that it is a public process with an administrative hearing; notice is sent out to adjacent property owners. At the hearing, the applicant presents their case to the Building Official; Planning and sometimes Public Works staff are present as well. Koppes asked how long that process takes. Howard said it typically takes a few weeks. Howard explained that in cases where previously developed property is being redeveloped but all principal buildings have been demolished or destroyed, the site should be treated as new development and brought into code compliance. Howard said that Paragraph 4 addresses properties where a new use is being established in a building with multiple tenants. She said that in these cases the new language states that only the most important of the site development standards must be brought into compliance; these are: screening parking areas and outdoor storage and display areas from the public street, parks, trails, and/or the Iowa River; planting any required street trees along the frontage; and bicycle parking. All other site development standards are allowed to remain noncompliant, including interior parking lot landscaping, screening between properties, driveway width and access points, outdoor lighting, signage, etc. Miklo noted that the property owners can still ask for minor modifications to these requirements. Eastham asked what the conditions were for allowing a waiver or modification of one of these requirements. He said he understood one of them to be that if a modification would conflict with any other requirement of the code, it could be waived or modified. Howard cited the language in the code by way of explanation, stating: "... if meeting these standards or requirements would not be feasible or practical or would unduly affect the ability to use or re -use the property due to topography, location of existing buildings, or other site constraints, they may be modified or waived by minor modification." Eastham asked if it was the case that the other site development standards that were not included in the list of four had to always be complied with. Howard said that the property owner would not have to comply with the other site development standards; the property would be grandfathered in. Howard noted that if the property owner was building a new parking area or expanding a use, then that new parking area would have to be built to code compliance. Payne clarified that if a use changes within a mall because a new store moved in, the mall would not be required to bring their entire parking lot up to code under the new provisions. Freerks asked staff how any of this would affect rooming houses, since most of them are non- conforming. Howard said that this would not affect the non -conforming use provisions, just nonconforming site development. Eastham said he was trying to consider these changes in light of the Miller Orchard neighborhood and its efforts to redevelop. Howard said that if a property is vacant and a new use moves into it, then the property would have to come up to code compliance or go through the minor modification process for anything they felt they could not comply with. Eastham asked if it was correct that the street -side screening would not be required if the property -owner could demonstrate that doing so would conflict with another code requirement. Howard said that this was already the case. Freerks said that what the new language does is spell out the way the process has been working by default. Howard said that time and time again issues would come up in redevelopment where the site development requirements simply did not make sense for a Planning and Zoning Commission May 17, 2010 - Informal Page 3 of 7 particular property. Eastham said what he is trying to understand was whether these changes would enhance or reduce the possibility of getting a better streetscape in the Miller Orchard neighborhood. Howard said that she does not know that it would change it a whole lot one way or the other. Payne said that really one could not know how a change in use would affect a given property until someone came in and asked for an allowance. Howard said that what these changes do is provide the opportunity for someone to ask for a minor modification. Howard said that the way minor modification is currently written, it seems as though the City did not really have the authority to waive things. Howard said that the City had granted a lot of minor modifications, but felt uncomfortable waiving things. Eastham said that he is concerned with the length of time it could take to change the Miller Orchard streetscape. Miklo said that one of staff's main concerns when the Building Department asked them to take a look at this was the landscaping between the parking lot and the street, and that is why it was retained as a requirement. Miklo said that while the landscaping between the parking lot and the street is subject to minor modification, there probably will not be a lot of difference in the streetscape because of these changes. 2. Discussion of an amendment to the Zoning Code to refine the definition of regulated stream corridors to exclude drainageways that do not have a bed and bank defined by an ordinary high water mark and a definite direction of flow. Howard said that the change here is to the definition of what is regulated. Howard said that presently, if there is a blue line in the USGS map, then the City treats that as a stream. However, sometimes in the field a specialist will discover that there is not really a stream there any longer. Howard said that sometimes this was due to errors in the maps, and sometimes it was due to tiling for agricultural purposes. Howard said that the City is trying to develop a system that does not conflict with the Army Corp of Engineers. Miklo explained that as it stands now, by City code a stream on the USGS map is protected, whether it actually exists or not. With the code changes, the stream will have to have a defined bed and bank. Freerks noted that these items could be voted on at the formal meeting or deferred. REZONING/DEVELOPMENT ITEM: REZ10-00006 &SUB10-00002: Discussion of an application submitted by TNT Land Development LLC for a preliminary plat and rezoning from Low Density Single Family (RS-5) to Planned Development Overlay — Low Density Single Family (OPD-5) for Terra Verde, a 58-lot, 23.22-acre residential subdivision located at 2949 Rochester Avenue. Miklo stated that this item should be deferred indefinitely. He said that once a mitigation plan is received the item will return to the agenda. Miklo said that the neighbors and attendees of the last meeting on this item will be notified of the deferral. REZONING ITEM: REZ10-00008: Discussion of an application submitted by Dealer Properties IC, LLC for a rezoning from Highway Commercial (CH-1) to Intensive Commercial (CI-1) zone for approximately 22.83 acres of property located west of Mormon Trek, south of Highway 1, adjacent to City View Drive. Rosenberg explained that Lot 1 of this property is already developed as a car dealership, Billion Planning and Zoning Commission May 17, 2010 - Informal Page 4 of 7 Honda. The property was annexed in 2003 to support the City's goal of enabling future development for commercial use along the Mormon Trek Boulevard extension and the airport. At the time, the property was zoned Highway Commercial (CH-1) to facilitate the development of service uses relating to expressways or other major arterial thoroughfares. These commercial enterprises include: food, lodging, motor vehicle service and fuel. At the time of that zoning, auto sales were allowed in the CH-1 zone. In 2005, a new zoning code was adopted which limited retail uses in the CH-1 zone to those necessary to serve highway traffic. As a result, the auto dealership on Lot 1 is non -conforming. Rosenberg said that at the time of development wetland mitigation and compensatory mitigation plans were required prior to subdivision due to a stream and associated wetlands in Outlot A of the property. Roesenberg said this was done in anticipation of the CH-1 zone, so further study needs to be done on whether these storm water facilities will be adequate for the extensive paving required for an outdoor storage use. The purpose of the CH-1 zone is to serve users of the expressways and arterial roadways. The original zoning encouraged the development of hotels and motels in the area. Rosenberg explained that the requested zone, Intensive Commercial (CI-1), is intended to provide areas for those sales and service uses whose operations are typically characterized by outdoor display and storage of merchandise. In this zone, special attention must be directed toward buffering negative aspects of allowed uses from adjacent residential zones. Rosenberg said that provided the concerns about the entranceway to the City are resolved, the Comprehensive Plan supports both CH-1 and CI-1 for the South Central District area's future land use scenario. The proximity of the property to Highway 218 and Highway 1 complicates the outdoor storage needs and what kind of CI-1 business can be established at that location. The Comprehensive Plan looks at that area specifically as an entranceway to the city and recommends that any CI-1 activity established there pays attention to aesthetics as it develops. The Comprehensive Plan calls for a consistent streetscape and discourages visibility of the rear of intensive commercial use from the highway. Staff feels it is appropriate to require a Conditional Zoning Agreement (CZA) that ensures the property develops in a way that conforms to the Comprehensive Plan. Issues that could be addressed by a CZA include: 1. Landscaping requirements for frontages on Mormon Trek Boulevard, Highway 218 and Highway 1. 2. Building and site design standards that address the appearance of the development and the location and screening of loading docks, garbage dumpsters, outdoor storage areas and other service areas or equipment. 3. Restrictions on lighting (if any) deemed necessary by the Airport Manager. 4. The provision of an adequate buffer from the residential properties located to the south. Staff believes the CI-1 zone would be compatible with neighboring uses if these conditions were met. Rosenberg noted that there are some existing residential areas in the county to the south of this area, and it needs to be determined to what extent the existing trees provide buffer to that area. He said that there may be a benefit to requiring additional S-3 screening. Planning and Zoning Commission May 17, 2010 - Informal Page 5 of 7 Rosenberg stated that there is a benefit to clustering car dealerships in that area. Staff recommends approval of this application subject to a CZA with the conditions previously outlined. Koppes asked if there were any other CH-1 zones in existence in the Iowa City area. Miklo said he believed there was some, but would have to check and get back to the Commission with that information. Koppes said that it seems as though this area is constantly rezoned based on what business wants to locate there at a given time. Eastham asked if other businesses in the area Miklo said any business within 300 feet would that a sign is also posted. would all be notified of this rezoning proposal. lave been notified. Greenwood Hektoen noted Freerks noted that this could either be voted on or deferred at the formal meeting. Miklo said the CH-1 zone was originally developed in 1983 when the zoning code was adopted because it was thought that there should be a place reserved at interchanges for certain uses. Miklo said the idea was to provide space at interchanges for gas stations and hotel opportunities for travelers. In the previous zoning code, the CC-2 zone did not allow hotels, so that was broadened when the zoning code was updated. Miklo said that theoretically if this rezoning was approved, there would still be the possibility of hotel/motel location at this interchange in the CC- 2 area. Freerks said it sounded like there is some overlap between the zones, and that there may not be anything specific to the CH-1 zone that cannot be addressed by another zone. Miklo said that may be a good question: is the CH-1 zone needed if the same uses are accommodated in the CC-2 zone? OTHER: Presentation of Fair Housina by Kristen Watson: Miklo stated that Watson works for the Human Rights Commission. Miklo said that the City had made a commitment in the Consolidated Plan to provide training for boards and commissions on the Fair Housing Act. Watson explained that she was an investigator for the City in the Human Rights Department. She said that part of what they do is to investigate housing discrimination complaints. Watson said that Iowa has an amazing civil rights history that extends to back before Iowa was even a state. Iowa was among the first states to refuse to acknowledge the validity of slave contracts over runaway slaves, desegregate schools, and to allow females and people of color to be attorneys. Nonetheless, there is also a history of housing discrimination and covenants restricting homeownership in certain areas to white Christians. The Fair Housing Act prohibits discrimination on the basis of race, color, national origin, religion, family status and disability. Iowa takes the federal law a bit further by adding prohibitions on discrimination based on creed, sexual orientation and gender identity, and retaliation. Iowa City also prohibits discrimination based on public assistance as a source of income. Watson noted Planning and Zoning Commission May 17, 2010 - Informal Page 6 of 7 that there are some very narrow, common-sense exceptions for: religious institutions, owner - occupied units, and dormitories (restrictions based on sex), familial status (elderly housing). Watson said that there can be restrictions in housing, but that they cannot be for discriminatory purposes. Watson said that one thing municipalities need to be careful about is that proof of discriminatory intent is not necessarily required for a successful lawsuit; all that has to be proved is discriminatory affect. A discussion was held on specific scenarios to which housing discrimination laws and liabilities applied.

HARVAT HALL MEMBERS PRESENT: Charlie Eastham, Ann Freerks, Elizabeth Koppes, Wally Plahutnik, Tim Weitzel MEMBERS ABSENT: Josh Busard, Michelle Payne STAFF PRESENT: Bob Miklo, Jacob Rosenberg, Karen Howard, Sara Greenwood Hektoen OTHERS PRESENT: Dave Larsen, Glenn Siders, Steve Goetzelman, Kent Ralston RECOMMENDATIONS TO CITY COUNCIL: 1. The Commission voted 5-0 (Busard and Payne absent) to approve REZ10-00008, an application submitted by Dealer Properties IC, LLC for a rezoning from Highway Commercial (CH-1) to Intensive Commercial (CI-1) zone for approximately 22.83 acres of property located west of Mormon Trek, south of Highway 1, adjacent to City View Drive, subject to a Conditional Zoning Agreement (CZA) that addresses the following: 1. Landscaping requirements for frontages on Mormon Trek Boulevard, Highway 218 and Highway 1 to be approved by staff. 2. Building and site design standards that address the appearance of the development and the location and screening of loading docks, garbage dumpsters, outdoor storage areas and other service areas or equipment. 3. Restrictions on lighting as deemed necessary by the Airport Manager. 4. The provision of an adequate buffer from the residential properties located to the south. 2.

PUBLIC DISCUSSION OF ANY ITEM NOT ON THE AGENDA: Planning and Zoning Commission May 20, 2010 - Formal Page 2 of 11 None. REZONINGIDEVELOPMENT ITEM: REZ10-00006 &SUB10-00002: Discussion of an application submitted by TNT Land Development LLC for a preliminary plat and rezoning from Low Density Single Family (RS-5) to Planned Development Overlay — Low Density Single Family (OPD-5) for Terra Verde, a 58-lot, 23.22-acre residential subdivision located at 2949 Rochester Avenue. Miklo stated that this item needed to be deferred indefinitely. Staff is waiting for a wetland mitigation plan, as well as a plan the addresses the woodlands and the stream corridor on the property. Freerks opened the public hearing. No one wished to speak to the issue and the public hearing was closed. Weitzel motioned to defer the application indefinitely. Koppes seconded. Eastham noted that he would be abstaining from this item. A vote was taken and the motion to defer carried 3-0 (Eastham abstaining; Plahutnik not present at time of the vote; Busard and Payne absent). REZONING ITEM: REZ10-00008: Discussion of an application submitted by Dealer Properties IC, LLC for a rezoning from Highway Commercial (CH-1) to Intensive Commercial (CI-1) zone for approximately 22.83 acres of property located west of Mormon Trek, south of Highway 1, adjacent to City View Drive. Jacob Rosenberg stated that the applicant is requesting the rezoning to allow for the property to be used as a car dealership and collision repair facility. Rosenberg said that Lot 1 of the subject property is currently occupied by Billion Honda car dealership. The applicant has indicated that they may re -subdivide in the future. Rosenberg said that the property was annexed by Iowa City in 2003 to support the City's goal of developing commercial areas near the airport. At the time, the property was zoned Highway Commercial (CH-1) to facilitate the development of service uses relating to expressways or other major arterial thoroughfares. These commercial enterprises include: food, lodging, motor vehicle service and fuel. At the time of that zoning, auto sales were allowed in the CH-1 zone. In 2005, a new zoning code was adopted which limited retail uses in the CH-1 zone to those necessary to serve highway traffic. As a result, the auto dealership on Lot 1 is non -conforming. Rosenberg explained that the requested zone, Intensive Commercial (CI-1), is intended to provide areas for those sales and service uses whose operations are typically characterized by outdoor display and storage of merchandise. In this zone, special attention must be directed toward buffering negative aspects of allowed uses from adjacent residential zones. Planning and Zoning Commission May 20, 2010 - Formal Page 3 of 11 Rosenberg noted that the Comprehensive Plan supports both CH-1 and CI-1 for the South Central District area's future land use scenario. The plan identifies the subject property and neighboring properties as suitable for large lot commercial uses with extensive outdoor storage. However, because the area serves as an entranceway to the city, the Plan also stresses the importance of aesthetics as the area develops. Rosenberg explained that the South Central District Plan specifies that intensive commercial properties on such entranceways are expected to upgrade landscaping and other design features to provide a consistent and attractive streetscape. He said that staff feels a Conditional Zoning Agreement (CZA) that includes standards to ensure that the property develops in a way that conforms to the policies of the Comprehensive Plan would be appropriate. Such a CZA would address landscaping, screening, and building and site design approval. Rosenberg said that the property is highly visible from Highway 218, and that staff would like to see a landscape buffer located in the rear of the property. He explained that Outlot B is a storm water management area, and that a wetland mitigation and compensatory mitigation plan were required prior to the subdivision of the property. However, there is some question as to whether those facilities would still be adequate for the proposed use. Calculations will need to be submitted to the City Engineer to assure that there will be adequate storm water storage. Rosenberg stated that provided that the concerns regarding the appearance of an entranceway to the city are addressed and all residential areas are adequately buffered, staff believes that the CI-1 zone would be compatible with the neighboring land uses. Rosenberg said the presence of a number of other car dealerships in the area would be a benefit as it results in the clustering of like -businesses. Rosenberg said that there are not many other CH-1 zones in the city, roughly 35 acres. He said there is a notable amount of undeveloped CH-1 zone located at Highway 1 and Interstate 80. Staff recommends that REZ10-00008, an application to rezone 22.38 acres of land at Mormon Trek Boulevard and City View Drive, be approved subject to a Conditional Zoning Agreement that addresses the following: 1. Landscaping requirements for frontages on Mormon Trek Boulevard, Highway 218 and Highway 1. 2. Building and site design standards that address the appearance of the development and the location and screening of loading docks, garbage dumpsters, outdoor storage areas and other service areas or equipment. 3. The provision of an adequate buffer from the residential properties located to the south. Miklo added that the concern regarding the appearance from Highway 218 does not concern the display lot; rather, it is the back of the dealership, which will have dumpsters and storage lots. Freerks asked if the 35-acres of CH-1 referenced by Rosenberg included the subject property; Rosenberg clarified that it did not include the subject property. Koppes asked to be shown where staff desired to have screening on the south side. Rosenberg said that there were trees in that area, but not very many. He said that the applicant is proposing an auto repair facility for that lot and staff has concerns about buffering those areas from the view of residential uses. Miklo said the outlot is fairly wooded. Koppes asked if the Planning and Zoning Commission May 20, 2010 - Formal Page 4 of 11 wooded area would be protected and Miklo said that it would as it is an outlot for storm water management and a wetland area, so no development could occur there. Eastham asked if access to the ID-RS area to the south was a concern. Miklo said that one of the reasons the area is zoned ID-RS is because there is no access. He said that the area would require access from the property to the south. He said there is some question as to whether it will ever be developable. The property owner to the south is doing a prairie restoration on his land and has talked about the possibility of dedicating the prairie to the City as open space. Miklo said that given the topography and the terrain, the only access would have to come from the neighboring property. Eastham asked if the provisions of the CZA would allow input of the tone and or shade of the exterior finish of the buildings. Miklo said the primary concern with that would be to avoid such things as corrugated metal buildings. Miklo said that such conditions have been imposed on Scott Six Industrial Park and the lots along Scott Boulevard. In that case the requirement was that areas visible from the street must have masonry or architectural metal finishes. He said that he did not believe color or details beyond general language regarding building materials and screening of loading docks would be justified in this case. Eastham asked about the covenant governing the property. Miklo said that the covenant applies to JJR Davis and specifies that property visible from public streets have to have a masonry or architectural metal finish. Miklo said that the City has does not enforce covenants. As a result, if such a requirement was desired by the Commission, then it would be appropriate for inclusion in a CZA. Freerks opened the public hearing. Dave Larsen, 277 Hickory, Kalona, appeared on behalf of the applicant. Eastham noted that the current dealership, Billion Honda, is bright white and is very prominently displayed. He asked Larsen if it was his experience that dealerships tend to insist on very obvious buildings or if they would be open to a more toned -down appearance. Larsen said that some dealerships are open to that, and some are not. Larsen said that his understanding for the design of the buildings in question is that they will be of similar metal panels to those used in the Billion Honda building. Larsen said that there is only one residential property visible from part of the property, and the dealership is purchasing that home and removing it. He said there is already a substantial amount of screening for the area. He noted that there are not only trees along the property line, but that a portion of it is also elevated, further blocking views of the proposed dealership. He circulated photographs to demonstrate this point. Larsen said that his original vision was for a hotel on the property on the Menard's side of the road; however, the three or four hotels that have expressed interest have been unable to obtain financing. He said that as a result, they are interested in rezoning that area to commercial as well. Miklo noted that the trees described by Larsen are along a creek bed and are not currently under the control of the applicant. Staff thinks that it would be helpful to have some S3 screening along the southern portion of the lot or the outlot to assure that the existing residential neighborhood is buffered from the proposed CI-1 zoning. Larsen said that it is the request of the applicant to have the matter voted on at this evening's Planning and Zoning Commission May 20, 2010 - Formal Page 5 of 11 meeting as they are attempting to move forward as quickly as possible. Freerks noted that Larsen had indicated they would follow the good neighbor policy. She asked if they had met with anyone. Larsen said that all of the important people had been made aware of the plans for the property. Greenwood Hektoen noted that it takes four votes to approve a rezoning. Freerks invited other members of the public to speak to the issue. No one wished to speak and the public hearing was closed. Koppes motioned to approve REZ10-00008 subject to a Conditional Zoning Agreement that addresses the following: 1. Landscaping requirements for frontages on Mormon Trek Boulevard, Highway 218 and Highway 1 to be approved by staff. 2. Building and site design standards that address the appearance of the development and the location and screening of loading docks, garbage dumpsters, outdoor storage areas and other service areas or equipment. 3. Restrictions on lighting as deemed necessary by the Airport Manager. 4. The provision of an adequate buffer from the residential properties located to the south. Eastham seconded. Eastham said that the only difficulty he has with car dealerships in that area is that the buildings tend to have a very large, light exterior. He said that with two or three buildings in one area that could be a factor. He said that he understood that the Commission may have limited control over that. Koppes said she is fine with rezoning the area CI-1, but that the Commission may need to examine whether CH-1 is really a legitimate zone at this point. She would like to see the zoning for that area become stable and not continuously before the Commission for changes. Plahutnik said that he realized he was jumping into the meeting a little late, but that he agrees with Koppes in that he does not like the idea of zoning and rezoning an area multiple times. However, he said he also understood that it was an area that for the most part is undeveloped and that a lot depends on what kind of businesses people are able to get into the area. Freerks asked Plahutnik if he had attended the informal meeting and if he had heard what the applicant had presented at this meeting. Plahutnik said he had. Weitzel said that in reviewing the Comprehensive Plan, he has determined that the CZA is appropriate and necessary for maintaining an attractive entranceway to the City. Freerks said that she felt it would be good to bring the car dealership into conformance. She said that either zone would be consistent with the Comprehensive Plan and she agrees that the back and forth zoning is not good for the area. She said she hates to see the dwindling of the CH-1 zone; however, as was discussed at the informal meeting, there is a lot of overlap between CH-1 and other zones. She agreed that it might be good for the Commission to further consider the future of the CH-1 zone. She said she did not have a problem with the color Planning and Zoning Commission May 20, 2010 - Formal Page 6 of 11 chosen by the applicant so long as it conformed to design standards and passed staff review, and that she did believe the buffer was necessary. A vote was taken and the motion carried 5-0 (Busard and Payne absent). ZONING CODE ITEMS: Discussion of an amendment to the Zoning Code to allow more flexibility in the application of development standards as they apply to nonconforming developments. Howard explained that nonconforming situations occur when the zoning designation of a property is changed or zoning regulations change such that existing, lawfully established uses, structures or lots no longer comply with zoning regulations. Without provisions in the code to address nonconforming situations, properties would have to immediately be brought into compliance when the code or zoning changed. The codes governing nonconformance provide relief to property owners and address a whole variety of situations that could occur over many years as property develops, redevelops and/or changes hands. Howard said the intent of the policy is to guide future uses and development so that it is consistent with City policy, to protect the character of an area, and to bring, over time, development into compliance with City regulations. Howard noted that there can be many different types of nonconforming situations, but that the matter before the Commission this evening involves nonconforming development. "Nonconforming development" is defined as an element of development such as a parking area, a loading area, outdoor lighting, landscaping, and other site elements that were established in conformance with code but which subsequently became nonconforming due to a change in the regulations or a change in the zoning designation of the property. Howard said that in 2005, the City revised its zoning code and specifically tried to address parking areas, outdoor storage areas, and buffering and screening standards. In doing so, the City attempted to address possible nonconformities in these areas. Even though allowances have been made to be more flexible as nonconforming properties redevelop over time, Howard said it is apparent that the code is not always flexible enough to address situations when uses change, particularly within multi -tenant buildings or shopping centers or when a property is vacant for a period of time. This has created a hardship for some property owners. Howard offered the example of a local mall in which each time a new tenant moved into the building the mall would be required by code to come into full compliance. Howard said the intent of the nonconforming regulations is to allow properties to more gradually make improvements to bring parking areas, outdoor storage and display area, etc into compliance. Howard shared a number of photographs that identified nonconforming sites, as well as photographs of sites in compliance with the most recent zoning code. Howard said that the goal is to bring properties into compliance over time, while creating a situation that is flexible enough to allow for consideration on a case by case basis as properties redevelop over time. Howard explained that the new provisions would deal with three basic situations: 1. When there is a change in use, whether it is within a multi -tenant building or a property with just one building or tenant space; 2. When a property is vacant and there is no principle use on the property; and Planning and Zoning Commission May 20, 2010 - Formal Page 7 of 11 3. When a use is proposed for a property where the buildings have been demolished or destroyed. Freerks opened the matter for discussion by the Commission Eastham asked if this would apply when a building is in a state of obvious disrepair. Howard clarified that the provisions concern uses, not buildings, adding that if a property has been vacant for a year with no principle use, then when a new use moves in the entire property must be brought up to code. Freerks asked who would be reviewing this process. Howard explained that if the property owner needed a minor modification that would be handled administratively by staff. Eastham noted that these provisions allow the Building Official to either modify or waive the standards. Howard said that the language allowing the Building Official to waive requirements came about as a result of instances where there has literally not been enough space on a site for it to be brought into compliance with all code requirements. Howard noted that the property owner would still be required to go through the minor modification process and justify their request. She said she predicted that complete waivers would be fairly rare and typically the applicant is required to mitigate for any potential negative impact that might occur because of the nonconforming situation. Freerks opened the public hearing. Glen Siders, Southgate Development Services, addressed the Commission. He said that he appreciates the City and staff looking into this matter; he has been frustrated by some of the challenges presented by the current code. He said that he appreciates Howard's memo, and concurs and endorses it. However, he said that as he reads the ordinance he does not see in its language some of the things Howard had said were addressed by it. Siders said that there are two situations that his development company has been confronted with the most. The first issue arises in situations where the parking begins closer to the property line than the required ten feet. He said he hoped that this issue could be addressed as a minor modification. The second issue, Siders said, results from requirements for landscaped islands in parking lots. Siders said that the staff memo indicates that parking lot standards would not be enforced in those cases; however, he did not see the language in the code that actually addressed that. Howard pointed out the portion of the code that would apply to the scenarios Siders proposed and confirmed that the new provisions, rather than requiring all elements to be brought into compliance would only require compliance with a few of the most important, including screening of parking, loading, outdoor storage and display areas along streetside lot lines and any adjacent park or public trail or the Iowa River (rather than along the sides and rear property lines) and planting street trees when applicable. Siders said that he always becomes a little nervous when he sees terms in an ordinance like "feasible," "practical," or "would unduly reduce the ability ..." Siders stated that this language was very subjective. He said he appreciates what the City is trying to do, but such subjectivity is cause for concern. He said that leaves interpretation open to whichever individual in a given department reviews a plan. Howard said that this subjective language is actually an improvement of the code because as it is written now, there is no means in the code to apply for or be granted a minor modification. Siders said he understood that, but that he could not help but be concerned by the subjectivity of the language. Freerks said the idea is that every situation needs to be assessed on its own terms because each situation is different. She said Planning and Zoning Commission May 20, 2010 - Formal Page 8 of 11 that the code could not say "always," as Siders might want it to and trying to come up with black and white language would take away the very flexibility that these provisions were intending to provide to property owners. Siders said he understood and he had no suggestions for alternative language. Steve Goetzelman, 632 Reno Street, said that he had opened a small business in Iowa City last April; that business was a change of use for the property, and the estimate to make the changes required to bring the property into compliance with code was somewhere around $180,000. Goetzelman said that they would never have been able to recoup those costs or even open the business if they had taken on those renovations. He said that they are currently operating with a temporary permit, but would like the opportunity to be more "official'. These changes in the zoning code would offer encouragement to small businesses, Goetzelman said. There were no further comments and the public hearing was closed. Freerks invited a motion. Koppes made a motion to approve an amendment to the Zoning Code to allow more flexibility in the application of development standards as they apply to nonconforming developments. Weitzel seconded. Eastham said he believed flexibility is a good thing and will generally improve the situation. Eastham said that he did have one concern, however. He reviewed the Neighbors for Miller Orchard Action Plan with a lens toward how these changes might affect the changes neighbors in that area wished to see. He said that beautification of entranceways to the areas was one of the goals of the plan, and he wondered how these zoning changes might improve or reduce the likelihood of changing those streetscapes. Eastham said he did not see language that required the Building Official to consider the needs for neighborhood improvements against the difficulty/hardships caused to the individual property owner if required to bring the site up to code. Koppes said that the flip side of that is that there is nothing to indicate that these changes will prevent improvements to the Miller Orchard area. Weitzel said that he felt the changes were positive. He said that it is good to allow a business to move in and open, and not to discourage new business with cost prohibitive standards. Weitzel said that while he believes the standards are good, this will provide another tool to the Building Official. He said that the language is subjective of necessity; if the goal is flexibility then there cannot be a lot of "shall' and "should" in the language. Weitzel said that decisions need to be well founded. He said he agreed that the priority should be on screening from public streets and sidewalks above putting trees in parking lots. He said the last requirement he would like to see waived would be screening from the street. Eastham agreed that the street screening is much more important than interior landscaping. Plahutnik said that in this case, the Commission is seeking to come up with general rules rather than looking at a specific case. He said that his review of the ordinance did not find anything to indicate that staff would roll-over for every request. He said that he was pretty sure that staff was rather tenacious about making sure that zoning standards are adhered to whenever possible. Plahutnik said that zoning is by its nature imprecise. He said that if it was found to be necessary, it would certainly be possible to come up with specific definitions for "undue", "feasible", etc. He said that language could also be added that takes a given neighborhood into Planning and Zoning Commission May 20, 2010 - Formal Page 9 of 11 account, and the fact that in certain instances requirements should not be waived. However, Plahutnik said, what is before the Commission represents a pretty good start. Freerks said she appreciated Eastham bringing up the Miller Orchard neighborhood plan. However, she said that she would not want any sections of the city to be exempted from the changes because she thought that could lead to greater problems. She noted that if businesses believed that it was more expensive to open in a given area due to zoning restrictions, it could lead that area into more problems when the goal had been to improve it. She said that she believed that the right decisions would be made in regard to waivers and flexibility. Freerks said it is always a balancing act. There was no further discussion on the matter. A vote was taken and the motion carried 5-0 (Busard and Payne absent). 2. Discussion of an amendment to the Zoning Code to refine the definition of regulated stream corridors to exclude drainageways that do not have a bed and bank defined by an ordinary high water mark and a definite direction of flow. Howard explained that currently the City relies on USGS quadrangle maps to define stream corridors, which are regulated in the City's sensitive areas ordinance. Howard said that while the maps are generally reliable, there are times when a specialist finds that a blue line does not signify an actual stream corridor. Howard said that this could be because the map is out -dated or because the map was simply incorrectly drawn due to reliance in aerial photos rather than field verification. Howard said staff would like to have the flexibility to have these types of things field -verified, and find that there is no stream if there is no defined bed and bank. Howard said this would bring the City into closer conformance to how the Army Corp of Engineers looks at and regulates stream corridors. Howard said that the changes to the code are fairly simple. Staff has added definitions and outlined exactly what wording would be deleted in the Environmental Review and Sensitive Areas Ordinance. Freerks opened the public hearing. No one wished to speak to the issue and the public hearing was closed. Weitzel motioned to approve an amendment to the Zoning Code to refine the definition of regulated stream corridors to exclude drainageways that do not have a bed and bank defined by an ordinary high water mark and a definite direction of flow. Koppes seconded. Plahutnik asked how areas that had formerly had stream -beds but had been disturbed by land movement or bulldozing would be treated. Howard said that in many cases streams had been degraded by tiling that was done on farmland; in those cases the streams are often no longer present. Howard said that the stream corridors the City wants to protect are those corridors that convey water within a channel that is visible on the ground even if the flow is intermittent. She said the goal is to protect the environmental value that streams provide. She said if there is no value left to protect, then there is no point in protecting the site of a former stream. Planning and Zoning Commission May 20, 2010 - Formal Page 10 of 11 Eastham asked if this approach was similar to what other communities in Iowa were doing. Howard said she believed Iowa City was far ahead of other communities in Iowa with regard to our environmental regulations. She said there were very few communities that have a sensitive areas ordinance. She noted that in some instances, Iowa City's ordinance is stricter than the Army Corp of Engineers' regulations. A vote was taken and the motion carried 5-0 (Busard and Plahutnik absent). CONSIDERATION OF MEETING MINUTES: May 3, 2010 (informal) and May 6, 2010 (formal): Koppes motioned to approve the minutes. Eastham seconded. The minutes were approved 5-0 (Busard and Plahutnik absent). OTHER: Presentation of JCCOG Long Range Multi -Modal Transportation Plan by Kent Ralston. Ralston explained that JCCOG is the metropolitan planning organization for the Iowa City urbanized area. He said that their specialty is transportation planning; however, they do some land -use and human services planning as well. The Multi -Modal Transportation Plan is a document that helps guide decision making about transportation improvements and funding 25 years into the future. Ralston said that they try to ensure that planning efforts are continual, comprehensive, and coordinated. This plan must be updated every five years, per federal regulations; the next plan is due by May 2012. Ralston said that the plan covers all aspects and modes of transportation. Ralston shared a number of different maps with the Commission that are included in the plan. He said that they would be happy to present again when the latest version was farther along. ADJOURNMENT: The meeting was adjourned on a 5-0 vote (Busard and Payne absent) at 8:18 p.m. s/pcd/mins/p&z/2010/p&z 05-20-10.doc z 0 U) V) 00 V W 0L ZUo 0 z N Gcl Q H z Q z z J a C9 z H W w Q XXXXXXx Ln XXXXXX 1 XXXXXX0 M XXXXXX N X X X X X X X N XXXXXX x V- N �LU Cl) NOO('M H X o 0 0 0 0 0 0 w W a J w J J J Q Q w N = z N oL)aW�Y� J W c Ix W LLl N N� N W dO Q~ Q z mwLLYa(L3 QmQJw O z H w w 0 LL z -- XXXXXX U)XXXXXXw XXXX - XX NXXXX�X� M NXXXXXX� W�.—MNOOM wmU-)0 d)0LO00 F.XO000000 w W ~ujJ mQ Q 2 Q z Q W N2zN=�� 0V<-juY� GQYVj�Nw � _ ce W W :D W N wQF-waz=F- zmww32a.a3 OQJW E 0 D � 0 0 V)z U 0) C Q x E LU c��Eco QZ o Q II II z II II W 2 1 xo'oz
