Throughout the project, we have been asking for feedback on plan components through a series of workshops and public meetings. COMMENTS: J r ell OJ M1 Have questions? Patrick Cotter,PDC Engineers patrickcotter@pdceng.com Donna Glenz, City of Seward Community Development dglenz@cityofseward.net City of Seward, as part of its comprehensive plan, would like to pass planning legislation to ensure protection of environmental systems and provide public recreational access to local natural resources. The codification of Environmental Protection Overlay Districts (OD) would aptly restrict development in those areas that are sensitive to structural development and which would be negatively affected by certain uses. An OD superimposes the underlying zoning classification; it is (often) more restrictive of land use and/or demands more requirements during the permitting process. An OD allows for some economic use of the land in the zoning classification that falls under it. (Failure to do so would constitute a taking). It is the intention of an OD regulation to explain how site plans must be modified and which accessory uses are allowed in order to ensure the integrity of the underlying environmental system. Further geological samples and GIS analysis will be necessary to determine the zones that should be included in an OD. We know that there can be at least four potential districts: 1. Floodplain Overlay District 2. High Water Table Overlay District 3. Steep Slope Overlay District 4. Riparian Buffer Overlay District Each type of OD shall be described under the following headings: Purpose; Designation; Use Permitted by Right; Uses Permitted by Special Exception; Conditional Uses; Development Procedures (and optionally, Boundary Disputes and Appeal Procedures; Area, Yard and Height Regulations, etc.) The following briefly describes each OD and includes typical language that could be included: The Floodplain Overlay District should affect properties within a 100 Year Flood Plain and require standards complying with the Federal Insurance Administration's Requirements for Flood Management and State of Alaska Hazard Mitigation Plans. The High Water Table Overlay District should require extra development procedures, including (but not limited to) site plans that show existing soil and topographical conditions, proposed structure and building locations, street and driveway locations, final grade, stormwater management facilities, landscaping, and sanitary sewage facilities, as prepared by a registered architect; engineer and/or surveyor. Plans should demonstrate how problems of stormwater runoff, erosion, soil stabilization, on-lot sewage disposal, sediment control and all additional controls will not affect lands that contain a high water table. Further, lot areas should be at least 5 acres with a maximum of 5% impervious coverage. The Steep Slope Overlay District should affect properties located on slopes of fifteen percent (15%) or more. Land on slopes of twenty-five percent (2S%) or more r should not be altered, graded, cleared, built upon or otherwise altered unless necessary for access driveways, trails, or underground utilities, under certain requirements. For properties determined to be within the Steep Slope OD, an applicant should provide a topographical survey, which was prepared and certified by a licensed professional surveyor or engineer, showing two (2) foot contour intervals. Plans should show existing topography, proposed structure and building locations, street and driveway locations, stormwater management facilities, landscaping, sanitary sewage facilities, and final grade as prepared by a registered professional architect, engineer or landscape architect. Plans shall be accompanied by drawings or a statement of how problems of stormwater runoff, erosion, soil stabilization, on-lot sewage disposal, landscaping, sediment control, and all other associated problems will be overcome. A statement should be submitted from the applicant's design engineer that all potential problems related to steep slopes have been resolved. The Riparian Buffer Overlay District establishes buffered zones around perennial streams, intermittent streams, alluvial soils, and wetland perimeters and ponds of more than 5,000 square feet. Zone One defines a buffer on the edge of a watercourse and is more restrictive. Zone Two defines a buffer on the edge of Zone One and is less restrictive. The purpose of this OD is to provide overall resource protection; reduce the amount of nutrients, sediment, organic matter, pesticides, and other harmful substances that reach watercourses; provide stream bank stability and shade which protects fish habitat and moderates stream temperature; protect such areas from increased erosion and runoff; conserve natural features important to land and water resources; secure environmentally sensitive lands; and minimize hazards to public health. Going Forward: Environmental Protection Overlay District Regulations must be established to match the conditions in the City of Seward and shall be approved by the legislative body for inclusion in the Code of Ordinances. However, since environmental systems cross municipal boundaries and much new development occurs in nearby unincorporated areas, coordination and cooperation with the KPB Planning Department is advised. Comprehensive soil surveys and slope samples in the City of Seward should be conducted.This data can be utilized in GIS to determine the boundaries of the ODs. Once the ON are established, a GIS technician can determine where ON overlap parcels and add the relevant Boolean attributes to the corresponding parcel features. Further,an ArcGIS too] Python script can be written which generate a "base plat" showing ON affecting the parcel, as well as known soils, building footprint dimensions, building setback, lot dimensions, slope and grade. The script could generate a design-controlled PDF for any specified parcel and include information relevant to that parcel from the Code of Ordinances. This PDF could be generated and downloaded from the KPB Parcel Viewer as a supplement to the PDF Parcel Report, perhaps imposing a fee as part of the permitting requirement. Seward,AK Code of Ordinances 15.05.025. - Land use districts---Established, definitions. (a) Established. The city is hereby divided into land use districts which shall be bounded and defined as shown on the official land use map. This official map, together with all explanatory matter thereon, as exhibited at the time of public hearing, is hereby adopted by reference and declared to be a part of this chapter. (b) Definitions—Purpose. (1) Rural residential district (RR). Intended to provide for stable, quiet, low density (one or two dwelling units per acre) detached single-family residential development, free from other uses except those which are both compatible and convenient to residents of such a district including recreational, religious and educational facilities of an appropriate scale and design complementary to the neighborhood character. (2) Single-family residential district R1 . Intended to provide for stable and quiet low to medium density(one to five dwelling units per acre) detached, single-family residential development, free from other uses except those which are both compatible and convenient to residents of such a district. (3) Two-family residential district M). Medium density(one to seven dwelling units per acre) transitional housing area with a mix of single and two-family units, free from other uses except those which are both compatible and convenient to residents of such a district. (4) Multi-family residential district R3 . Intended to provide opportunities for a higher density residential setting with a mix of housing units which are predominately multi- family units close to concentrations of public services, employment and/or recreation. This district may provide a transition between more intensive districts and lower density residential areas if sufficient screening and design features are provided to protect multi- family residences from undesirable effects. (5) Urban residential district (UR). Intended to allow an area of higher density mixed residential uses from detached single-family housing to multi-family apartments in conjunction with compatible low impact professional office uses in the area surrounding the downtown business district. (6) Office/residential district (OR). Intended to provide for medium density residential, commercial and office development designed to act as a transition zone between the high density central business district and surrounding medium-high density residential districts. (7) _..1. 1,3/2017 Seward,AK Code of Ordinances Harbor commercial district (HQ. Provides an area for water-dependent or water-related uses with particular emphasis on transportation, tourist, recreational, commercial or industrial enterprises which derive major economic or social benefit from a harbor location. (8) Auto commercial district (AC). Intended to provide areas to accommodate highway- oriented commercial activities such as offices, certain institutional uses, and limited personal services and retail uses requiring substantial outdoor activity, traffic and parking, and which also serve the offices and nearby residential areas, and which do not materially detract from nearby residential areas. (9) Central business district(CBD). Provides for an area of convenient, attractive, concentrated commercial development primarily intended for retail, financial, entertainment and professional services occurring within enclosed structures. Regulations applying to this zone are designed to encourage a compact group of businesses of the type which are mutually beneficial and located close enough together to encourage walk-in trade. (10) Industrial district (1), Established as a district in which the principal use of land is for business, manufacturing, processing, fabricating, repair, assembly, storage, wholesaling and distributing operations, which may create some nuisance and which are not properly associated nor compatible with residential land uses. It is intended to provide environmental safeguards for people employed in or visiting the district. Some visual amenity is expected in this district to make it compatible with adjoining residential or business districts. (11) Institutional district (INS). Public and private educational, administrative, government and health care uses, including public land reserve for future public development. The development standards are intended to set a high standard to assure that the activities provide visual amenity to the surrounding area. (12) Parks district(P). Is intended to designate park, recreation and commemorative property owned by the city, state or federal governments for recreation and other compatible public purposes. (13) Resource management district_(RM). Lands which are generally undeveloped and cannot be precisely zoned due to inadequate information on the extension of public services and utilities; the suitability of the land to support commercial, residential, industrial or public uses; and other possible environmental consideration.
