Minor amendments are subject to the Exception to the Site Design and Use Development Standards of chapter 18.5.2.050.E. 18.3.4.040 Use Regulations A. Plan overlay zones. There are four Land Use Designation Overlays zones within the Normal Neighborhood Plan are intended to accommodate a variety of housing opportunities, preserve natural areas and provide open space. 1. Plan NN-1-5 zone The use regulations and development standards are intended to create, maintain and promote single-dwelling neighborhood character. A variety of housing types are allowed, in addition to the detached single dwelling. Development standards that are largely the same as those for single dwellings ensure that the overall image and character of the single-dwelling neighborhood is maintained. 2. Plan NN-1-3.5 zone. The use regulations and development standards are intended to create, maintain and promote single-dwelling neighborhood character. A variety of housing types are allowed including multiple compact attached and/or detached dwellings. Dwellings may be grouped around common open space promoting a scale and character compatible with single family homes. Development standards that are largely the same as those for single dwellings ensure that the overall image and character of the single-dwelling neighborhood is maintained. Page 3 of 13 3. Plan NN-1-3.5-C zone. The use regulations and development standards are intended to provide housing opportunities for individual households through development of multiple compact attached and/or detached dwellings with the added allowance for neighborhood-serving commercial mixed- uses so that many of the activities of daily living can occur within the Normal Neighborhood. The public streets within the vicinity of the NN-1-3.5-C overlay are to provide sufficient on-street parking to accommodate ground floor neighborhood business uses. 4. Plan NN-2 zone. The use regulations and development standards are intended to create and maintain a range of housing choices, including multi-family housing within the context of the residential character of the Normal-Neighborhood Plan. B. Normal Neighborhood Plan Residential Building Types. The development standards for the Normal Neighborhood Plan will preserve neighborhood character by incorporating four distinct land use overlay areas with different concentrations of varying housing types. 1. Single Dwelling Residential Unit. A Single Dwelling Residential Unit is a detached residential building that contains a single dwelling with self-contained living facilities on one lot. It is separated from adjacent dwellings by private open space in the form of side yards and backyards, and set back from the public street or common green by a front yard. Auto parking is generally on the same lot in a garage, carport, or uncovered area. The garage may be detached or attached to the dwelling structure. 2. Accessory Residential Unit. An Accessory Residential Unit is a secondary dwelling unit on a lot, either attached to the single- family dwelling or in a detached building located on the same lot with a single-family dwelling, and having an independent means of entry. 3. Double Dwelling Residential Unit (Duplex). A Double Dwelling Residential Unit is a residential building that contains two dwellings located on a single lot, each with self-contained living facilities. Double Dwelling Residential Units must share a common wall or a common floor/ ceiling and are similar to a Single Dwelling Unit in appearance, height, massing and lot placement. 4. Attached Residential Unit. (Townhome, Row house) An Attached Residential Unit is single dwelling located on an individual lot which is attached along one or both sidewalls to an adjacent dwelling unit. Private open space may take the form of front yards, backyards, or upper level terraces. The dwelling unit may be set back from the public street or common green by a front yard. 5. Clustered Residential Units - Pedestrian-Oriented. Page 4 of 13 Pedestrian-Oriented Clustered Residential Units are multiple dwellings grouped around common open space that promote a scale and character compatible with single family homes. Units are typically arranged around a central common green under communal ownership. Auto parking is generally grouped in a shared surface area or areas. 6. Multiple Dwelling Residential Unit. Multiple Dwelling Residential Units are multiple dwellings that occupy a single building or multiple buildings on a single lot. Dwellings may take the form of condominiums or apartments. Auto parking is generally provided in a shared parking area or structured parking facility. 7. Cottage Housing. [Reserved] C. General Use Regulations. Uses and their accessory uses are permitted, special permitted or conditional uses in the Normal Neighborhood Plan area as listed in the Land Use Table.

The Common Green provides access for pedestrians and bicycles to abutting properties. Common greens are also intended to serve as a common open space amenity for residents The following approval criteria and standards apply to common greens: i. Common Greens must include at least 400 square feet of grassy area, play area, or dedicated gardening space, which must be at least 15 feet wide at its narrowest dimension. 2. Cottage Housing: [Reserved] 3. Conservation of Natural Areas. Development plans must preserve water quality, natural hydrology and habitat, and preserve biodiversity through protection of streams and wetlands. In addition to the requirements of 18.3.11 Water Resources Protection Zones (Overlays), conserving natural water systems must be considered in the site design through the application of the following guidelines: a.Designated stream and wetland protection areas are to be considered positive design elements and incorporated in the overall design of a given project. b.Native riparian plant materials must be planted in and adjacent to the creek to enhance habitat. c.Create a long-term management plan for on-site wetlands, streams, associated habitats and their buffers. 4. Storm Water Management. Storm water run-off, from building roofs, driveways, parking areas, sidewalks, and other hard surfaces must be managed through implementation of the following storm water management practices: a. When required by the City Engineer, the applicant must submit hydrology and hydraulic calculations, and drainage area maps to the City, to determine the quantity of predevelopment, and estimated post-development, storm water runoff and evaluate the effectiveness of storm water management strategies. Computations must be site specific and must account for conditions such as soil type, vegetative cover, impervious areas, existing drainage patterns, flood plain areas and wetlands. b. Future Peak Storm water flows and volumes shall not exceed the pre-development peak flow. The default value for pre-development peak flow is .25 CFS per acre. c. Detention volume must be sized for the 25 year, 24 hour peak flow and volume. d. Development must comply with one or more of following guidelines. i. Implement storm water management techniques that endeavor to treat the water as close as possible to the spot where it hits the ground through infiltration, evapotranspiration or through capture and reuse techniques. ii. Use on-site landscape-based water treatment methods to treat rainwater runoff from all surfaces, including parking lots, roofs, and sidewalks. iii. Use pervious or semi-pervious surfaces that allow water to infiltrate soil. Page 9 of 13 iv. Design grading and site plans that create a system that slows the stormwater, maximizing time for cleansing and infiltration. v. Maximizing the length of overland flow of storm water through bioswales and rain gardens, vi. Use structural soils in those environments that support pavements and trees yet are free draining. vii. Plant deep rooted native plants. viii, Replace metabolically active minerals, trace elements and microorganism rich compost in all soils disturbed through construction activities. 5. Off-Street Parking. Automobile parking, loading and circulation areas must comply with the requirements of chapter 18.4.3 Parking, Access, and Circulation Standards, and as follows: a. Neighborhood serving commercial uses within the NN-1-3.5-C zone must have parking primarily accommodated by the provision of public parking areas and on- street parking spaces, and are not required to provide private off-street parking or loading areas, except for residential uses where one space shall be provided per residential unit. 6. Neighborhood Module Concept plans. The Neighborhood Module Concept plans (i.e. development scenarios) are for the purpose of providing an example of developments that conform to the standards, and do not constitute independent approval criteria. Concept plans are attached to the end of this chapter. 7. Conformance with Open Space Network Plan: New developments must provide open space consistent with the design concepts within the Greenway and Open Space chapter of the Normal Neighborhood Plan Framework and in conformance with the Normal Neighborhood Plan Open Space Network Map. The open space network will be designed to support the neighborhood's distinctive character and provide passive recreational opportunities where people can connect with nature, where water resources are protected, and where riparian corridors and wetlands are preserved and enhanced. a) The application demonstrates that equal or better protection for identified resources will be ensured through restoration, enhancement, and mitigation measures. b) The application demonstrates that connections between open spaces are created and maintained providing for an interlinked system of greenways. c) The application demonstrates that open spaces function to provide habitat for wildlife, promote environmental quality by absorbing, storing, and releasing storm water, and protect future development from flood hazards. d) The application demonstrates that scenic views considered important to the community are protected, and community character and quality of life are preserved by buffering areas of development from one another. Page 10 of 13 18.3.4.65 Exception to the Site Development and Design Standards An exception to the requirements Site Development and Design Standards must follow the procedures and approval criteria adopted under section 18.4.1.030, unless authorized under the procedures for a major amendment to plan. 18.3.4.070. Open Space Area Overlay All projects containing land identified as Open Space Areas on the Normal Neighborhood Plan Open Space Network Map, unless otherwise amended per section 18.3.030.C, must dedicate those areas as: common areas, public open space, or private open space protected by restrictive covenant. It is recognized that the master planning of the properties as part of the Normal Neighborhood Plan imparted significant value to the land, and the reservation of lands for recreational open space and conservation purposes is proportional to the value bestowed upon the property through the change in zoning designation and future annexation. 18.3.4.075. Advance Financing District [Reserved] 18.3.4.080. Review and Approval Procedure. All land use applications are to be reviewed and processed in accordance with the applicable procedures of Part 18.5. Page 11 of 13 Neighborhood Module Concept plans The City recognizes that future innovations in building technologies, water conservation practices, and creative approaches to site design and layout will help shape the neighborhood module concept in consideration of the unique characteristics of the properties being developed. As such these example illustrations presented are primarily intended to assist those involved in conceptualizing a development to better address the principle objectives outlined within the Normal Neighborhood Plan. ig<a! 5ti et Natural area rgeser I~ f r-z ° W.j ~ l Person l and 1 ~ _ ~ crsmtt~unity t cprdenz space x s Avaatetyo Aak AWL k housing tsp~-~ Q e• and sees f , s m t SOW ('AWT~led z buildings -sr- ' Common - center greens - Arai- ,mow... 1 G", Consolidated } i pkl:Yiart'zl5 +.gr^, -mss 40 ~~strtcf 3~t €sti.a accessed Fy alleys aI'y Page 12 of 13 Normal Neighborhood District Zoning Classification Map. a MAIN ~f § ,f p:e ~ a a _ . sad sid .r #p E 'rd a p~k~ 7.
