6.6. SR 04-16-2001River 13065 Orono Parkway Elk River, MN 55330 TO: FROM: DATE: SUBJECT: Item # 6.6. MEMORANDUM Mayor and City Council Scott Harlicker, Senior Planne/r~ April 16, 2001 Case No. OA 01- 01 Request by City of Elk River to Amend the Cluster Ordinance Request Consider a request by the City of Elk River to amend the cluster subdivision ordinance. Attachments · Design standards - Liberty of the Lake · Ordinance Amendment OA 01- Overview At the February 13th and February 27th Planning Commission meetings, the Commission and staff discussed concerns that have been raised by the City Council, the Planning Commission and staff. The Commission then gave staff direction regarding amendments to the cluster ordinance to address the issues raised. Cluster Developments in the A1 District The Commission had a lengthy discussion of the use of cluster developments in the A1 district. We discussed whether the density bonus is too high and whether limiting the use of the ordinance to within a certain distance of the existing developed areas would control cluster developments. The Commission felt that neither of these options would effectively reduce the use of cluster developments in the outer reaches of the City. Furthermore, the Commission did not feel use of cluster developments in the northern portion of the A1 district was a major problem. Phone: 763.441.7420 Fax: 763.441.7425 www. ci.elk-rivenmn.us Memo to Planning Commission/OA 01-01 February 27, 2001 Page 2 Quality of Open Space As a method to preserve higher quality open space, the Commission suggested that at least 35% of the open space be "buildable area". Buildable area is defined as gross land area less the land that includes floodways, hydric and restrictive soils, lands with slopes greater than 33%, wetlands, and areas that can not accommodate septic systems. The ordinance should also be amended to give the City the option of requiring that shoreland and areas along streams be included as preserved open space. The Commission also thought that the 5% density bonus for additional 10% open space, above the required 50%, should only given if the additional 10% is buildable. The Commission felt that the maximum lot size allowed should be 2~A acres and that if the maximum lots size is % acre there should be a 5% density bonus. Architectural Theme The Commission felt a written narrative describing the architectural theme of a project should be provided at the same time that the preliminary plat is submitted. The 5% bonus should also be further broken down. Landscape theme, lighting theme and a common open space/central gathering place would make up 2.5% of the density bonus and additional architectural elements would make up 2.5% of the density bonus. Front Yard Setback The current minimum front yard setback of 30 feet is too restrictive and does not allow developers to create more pedestrian friendly, walkable neighborhoods. By reducing the minimum front yard setback to 20 feet, a developer would have more flexibility in design and additional trees could be preserved. The Commission wanted the garages to have a less dominant presence in the streetscape and recommend that garages be setback back further than the house. A 30 foot minimum setback for garages was recommended. Density Bonus Calculations It is currently not clear how the 5% density bonus should be calculated, whether it is based on zoning district density or the open space density. The intention was that it should be based on the zoning district density, and the following formula should be included to make it clear: S:\PLAN NIN G\SCO'I-r~OA0101 CC.DOC Memo to Planning Commission/OA 01-01 February 27, 2001 Page 3 Rla district - eligible land 24 ac. Density bonus: (24/2.5) x .05 - .48 In this example each 5% density bonus would be worth .48 lots A1 district - eligible land 42 ac. Density bonus: (42/10) x .05 -- .21 In this example each 5% density bonus would be worth .21 lots Park Dedication Requirements The Commission also reviewed the park dedication requirements. Under the current ordinance the park dedication fee is based on the number of lots allowed per based density, not on the total number of lots platted. For instance, with Ridges of Rice Lake, the park dedication fee would be based on the base density allowed under the A1 zoning district (273 ac./10 - 27.3 or 27 lots). The alternative would be based on the total number of lots platted, which in this case is 70. The Commission recommended that park dedication requirements be based on the total number of lots platted. Recommendation The Planning Commission and staff recommend that the City council approve attached ordinance amendment approving the following amendments to the cluster ordinance: 1. 35% of the preserved open space be buildable area. 2. The City have the option of requiring that shoreline and areas along streams be included as preserved open space. 3. The additional 10% open space, above the required 50%, provided to receive the 5% density bonus be buildable area. 4. The maximum lot size allowed shall be 2 ½ acres. 5. If the maximum lot size in a project is ½ acre or less, the developer will receive a 5% density bonus. 6. Landscape theme, lighting theme and a common open space/central gathering place would make up 2.5% of the 5% density bonus for architectural theme and the architectural theme of the houses would make up other 2.5% of the density bonus. 7. A written narrative describing the architectural theme of a project be provided with the submittal of the preliminary plat. 8. The minimum front yard setback for house shall be 20 feet and the minimum front yard setback for garages shall be 30 feet.

Front 30' Side 10' Garage Side 5' Rear 20' 20' house 30' garage c. Maximum impervious surface within each lot shall be 25%. d. Street Standards shall comply with the Elk River Subdivision Ordinance, section 1008. e. Accessory structures shall be allowed on preserved open space lots without a principle structure as provided for in the developers agreement. vii. Lot Design Guidelines. Residential lots should be designed to achieve one or more of the following objectives: a. Oriented around a central focal point such as: i) A central green or square ii) A physical amenity such as a meadow, stand of trees, a stream or water body, or some other natural feature. iii) A street with a boulevard planted with shade trees and a central parkway or median at least 25 feet wide. b. Located to preserve woodlands, farmland or other natural features or character including places of historic, archeological or cultural value and their environs. c. Located such that at least 50% of the lots within a neighborhood abut open space on at least one side. A local street may separate lots from open space. d. Views shall be preserved on and off-site to the maximum possible. e. Locate neighborhood recreation open spaces such that they are an integral part of the neighborhood or the surrounding home sites, are at an elevation appropriate to their intended recreational use, have boundaries that are clearly defined and are accessible to all neighborhood residents from a public street. f. Preserve.natural habitat to the maximum extent possible in a contiguous, connected configuration. Natural open spaces may include, but are not limited to, fields, wetlands, slopes, bluffs, woods, lakes, ponds, streams, shore lands, and other environmentally sensitive areas. g. Connect individual home sites with pedestrian corridors or sidewalks to larger open spaces and places of destination on and off site. Open spaces should be accessible to pedestrians at roughly (1,200) foot intervals along public roadways. Pedestrian corridors between lots shall be at least (50) feet in width and buffered from view of adjacent properties. h. Buffer residential properties from incompatible uses with buffer zones of at least (100) feet to minimize land use conflicts. The buffer zones shall be thickly planted with native grasses, shrubs and trees. Roads may be included in the buffer that will create an effective barrier separating yards from fields and pastures. i. Minimizes development fronting onto existing arterial roads by establishing buffer zones with existing and native vegetation to protect rural roadside character and to improve public safety and traffic carrying capacity. j. Locate houses and garages such that the garages do not dominate the streetscape. k. Locate septic systems on the most suitable soils for sub-surface septic disposal. 1. Landscape common areas and street right-of- ways with native vegetation with high wildlife conservation value. F. Density. To calculate the base density for a given tract: i. Determine the Eligible Land (See definition). ii. In the Rl-a zoning district, divide the eligible land by 2.5 then multiply by 1.15 to determine the number of lots. Example: Eligible land area: 24 acres Zoning district density: 2.5 acres OSP density: (24 / 2.5) x 1.15 = 11.04, or 11 lots iii. In the A-1 zoning district divide the eligible land by 10 and multiply by 2.15 to determine the number of lots. Example: Eligible land area: Zoning district density: OSP density: 42 acres 10 acres (42 / 10) x 2.15 = 9.03, or 9 lots iv. Density bonuses. At the discretion of the City Council, density bonuses may be permitted which allow projects to be developed at a density greater than otherwise allowed provided that one or more of the following standards are complied with. Each standard provides an additional density increase above the allowed zoning district density with a maximum density increase of 40% above the allowed zoning district base density. Example: Rla District eligible land area - 24 acres Density bonus: (24/2.5) x .05 = .48 Each 5% bonus = .48 lots A1 District eligible land area - 42 acres Density bonus: (42/10) x .05 = .21 Each 5% bonus = .21 lots a. Creating an endowment to the land trust or homeowners association where the principal would generate sufficient annual interest to cover the conservation easement holder's yearly costs (5% bonus). b. Providing for access by the general public to trails, parks, or other recreational facilities, excluding golf courses (5% bonus). c. An additional 10% open space is provided above the required 50% preserved Eligible Land. The additional 10% open space shall be buildable area (5% bonus). d. Reusing existing buildings and structures or preserving specific site features inventoried by the County, City, or State Historical Preservation Office (5% bonus). e. Provide covenants to create an architectural theme to include items such as, porches, side or rear loaded or detached garages (5% bonus). Landscape theme, lighting theme, and open space/central meeting place shall make up 2.5% of the density bonus and additional architectural elements shall make up 2.5% of the density bonus. A written narrative describing the architectural theme shall be provided with the preliminary plat. f. Maximum lot size h acre (5% bonus). Design Guidelines Architectural Review & Design Guidelines for: (3 EN ERA L L O T Careful siting of each home must seek to fit He topography, protect existing vegetation, views, open space and other features that define the character of this neighborhood. These guidelines will further this goal by establishing criteria aimed at achieving quality levels of landscape architecture and sensi- tive site plans. Our goal is beautiful streetscaFes and open spaces, irtterestin~ and complementary lot amenity features, paving and planting design. Careful consideration must be made for bature addi- tions, decks, fences, and screened porches. Consultation with a landscape consultant is recommended at the early stages of planning. SUMMARY De.sign for the umque aspects of y. our sEecif- ic site anti overall neigh- borhood. Refer to spe- cific tree sur- vey for your 10t' and !fy to assure the pr. eservation ot existing trees. EXAMPLE DETAIL A. HOME SITING 1. Home plan and siting should take advan- tage of sun, views a.nd provide for both racy and front yard neighboring opportuni- ties, while also creating attractive off-lot impacts and respecting sight lines of other homes. 2. Respect the existing topography and work with it. 3. ARC may require maintenance of sight lines of other homes to natural or built amen/ties. B. TREE PRESERVATION 1. Preserve undergrowth m protected forest areas. Pathways are appr0pr/ate 2. In concept planning identify the trees you will be savLng and those that appear to require removal. 3. tn the FINAL Review plan submittal, show the location, size species, a.nd elevation of existing trees greater than 8 roches in diameter and oaks, hickory and sugar maple greater than 2 ~nches kn d/ameter within the proposed area to be disturbed and within 20 feet thereof. 7/12/98 - rev.

On vertical curb streets, utilize existing curb cut or pay for new location and street repair. 3. Homes should be positioned with tn respect to existing homes and tn anticipa- tion of sitLug of future homes. (See: The A.R.C. Lot/Home Location Guide.) D. HOUSE-DOMINANT HOME DESIGNS 1. Reduced setbacks for homes require design of homes with "tamed garages", emphasizing a home's elevations and wi~ clear references to building massing and architectural detailing, including a recog- nizable style. E. LIBERTY'S REDUCED SETBACKS 1. 20' setback from property line (15' from back of most sidewalks) allows use of deeper floor plans (see City requirements). E TAMING THE GARAGE: 1. With reduced lot widths and budget con- scious home design, house dominant designs require creative two and three car garage positioning to screen, dLminish impact from road, while emphasizing home entry and approach. 2. Not less than two car or more than four spaces without ARC approval. 3. Garage positioning that maximizes house and minimizes garage: ie. · 3 car L- shaped garages with tandem spaces, turned garages at side streets, court yard and side load garages (where lot width permits).

Each home is to have a walk from the front entry/porch to the back of curb, preferably with steps near the street right-of-way line/back of side . walk (except flag lots). 3. PAVED AREA a. Homes without a front porch must have a paved surface built with appro priate, decorative paving, of at least 120 s.f.. A deciduous overstory or tmdersto ry tree, minimum 3" caliper must pro vide shade. RETAINING WALLS 1. In the FINAL Review plan submittal, show the top and bottom elevations or proposed retaining wails. 2. Design for front and rear yard natural areas. Position ground cover, trees and shrubs in response to ARC - recommended' tree massing, berming and natural area plans. Page 5 I I. GENERAL HOME DESIGN GUIDE S Each individual home shall have its own identity and ch.aracter. It will be aesthet4cally balanced, details consistent with its basic architectural style and be made with quality materials and workmanship. Homes identical to an established builder's model or portfolio will not be allowed and homes not demonstrating adequate design variety will not be approved by ARC. SUMMARY EXAMPLE Trellis/arbodpergola as garage camouflage. DETAIL A.~VISUAL IMPACTS 1. Create attractive off-lot visual impacts. Be mindful of the home's massLng as seen from surrounding road approaches and in context with other adjacent and surround homes. Avoid unaccented 2 & 3 story facades. 2. Respond to each lot's on and off- site opportunities to help define the home's outdoor spaces and guide positions of home interior spaces 3. Select home design/floor plans that establish a friendly relationship with the street via porches, decks, gradual level changes and anteways, entry sitting areas, courtyards, patios, terraces, sheltered entrys, etc. 4. Price efficiency can come with simpler, lower room count, "box-on-box" floor plans, blended with modern, shared-space room layouts. 5. "Stage front" appearance will not be approved, the sides and rear should sup- port the style of the home's front eleva- tions. 6. Camouflage garages with small set- ' backs from home front with porch exten- sions, arbors, trellises, wing walls or retaining walls. Use to help hide garbage & recycle bins. 7. Add steps from garage to home, pro- vide headroom at garage service door. Allow space for added risers in garage and/or transition rooms within home, such as laundry/mudroom. Design should reduce impact of blank area above garage door(s) (ie. lowered roof line, trim/details.) Page 6 SUMMARY EXAMPLE Provide main floor elevation that is raised 2 to 3 feet above the street ele- vation. Raise home particularly with reduced front setbacks DETAIL B. HOME TO BACK OF CURB ELEVATION 1. Raise home, with added front steps to capture old S~illwater [ook particu- larly wiff~ reduced setbacks.., can mm on-grade homes to look-outs, look- outs ~o walkouts. C. ROOF PITCHES 1. The roof on each home ts one of the most important visual masses on [he house. Roof slopes and overhangs must be appropriate to [he individual styie: Research your style, know its conventions. 2. Design and refine well [hought out, simple and strong roof forms. D. HARDSCAPE TERRACES/PORCHES/OUTDOOR LIVING SPACE 1. Outdoor I~ving spaces can provide effec- tive ~ransition between home, outdoors, and a place of interaction wiff~ neighbors. These could include patios, decks, gazebos or formal gardens. Page 7 IIII. DETAIL HOME DESIGN GUIDES SUMMARY EXAMPLE DETAIL A. PREFERRED STYLES · Designs utilizing modem floor plans within an architectural theme. · Colonial, · victorian, · federal, · farmhouse, · cape cod, · tudor · stick, · tudor, · craftsman, shingle · arts & crafts bungalow, B. PREFERRED MASSING · 2story, .story&l/2, · ranch,-2 story with attic dormers. C. GARAGE TREATMENTS 1. Use two-story/dormer elements over garages for architectural interest and bonus space. 2. Garage door accents and detailing should be used to break up its scale & designed to echo home style detailing, making it look less dominant, more a con- tinuation of the structure. Do not use plain flush steel doors. 3. Provide garage door treatments, win- dows designed to echo home style detail- ing. 4. Where there are garage wails with no doors, them should be windows that match other windows & trim/architectural details of the home. 5. In area below floor line and above grade, use stone, cultured rock, siding extensions, lattice, brick, stucco and verge boards. D. ENTRY PORCI-USTOOP 1. Provide a stoop or entry porch (of use- able size), large enough for plants and seat- lng. They should be covered by an over- hang, roof, tretli,s, portico or detail appro- priate to home style. Where a smaller sheltered entry ks planned, provide a front-oriented entry setting such as veranda, deck or patio suitably sized for a minimum of two chairs. Page 8 SUMMARY EXAMPLE DETAIL E.
