Both document, empha,i,e the need for better infill standards and overall higher quality design standards for downtown. They also provide a long range vision for the future development and redevelopment of the City and its future growth area. These documents present a community \'ision that seeks to improve existing design. It does this by focusing on mixed use, in fill and higher density development in key locations. Goals and Priorities for Downtown Redevelopment in the 2030 Plan include: Downtown and adjacent Lakefront Park are unique community focal points and destination attractions that contribute to the city's identity and offer opportunitle, for recreation, employmem, housing, shopping and dining.

Most buildings ()ll Downtown's central thoroughfare, l\lain .\venue, were constructed at the turn-of-the twentieth century with traditional building sizes and ]0,," of thaT time period, Typical lot sizes are 25-50 ft'et wide bv 100 feet deep. Buildings not on Main Street vary in stde _ scalc aml use. Included in this mix are government buildings and new mixed use development such as the Lakelron/ Nd'-Y mixed-use building. In order to ensure that pf{ljec,," satisfy the goals of the Comprehensive Plan and 2030 Vision and Strategic Plan, Prior Lake has developed these guidelines. Prior Lake was incorporated in 1858 and is located in central Scott Count\'. The Cin' has an estimated populatioll of 22,000, co\-ers 18.3 square miles, and is located tn the southern portion of the Minneapolis-Sf. Paul metropolitan area. Prior Lake has a Council/Manager form of government with five City Council members, 2-2 Prior L"kf JJ lo(atcd ill S,otl COlli/I)' ill tiN .I'll" 'JiJ'ill (1Iif'.1 IJ/dm ,m'd Prior J Alk,' dowlIIOIn/ ill (fIIlt,,.lookll!~ II'!'.!'/. ,.1 'ro 2.2 Urban Form and Historic Development Patterns 2.2.1 TRADITION Development has always been focused around the town square, the village green, or "~\lain Street". \X'ith the advent of modern planning practices, cities have typically been laid out on an urban gnd pattern of streets a nd blocks. Development and construction patterns In downtown districts have been characterized by a taller, "transparent" ground floor that is supportive of retail and service uses. Upper floors are rypically characterized by smaller "punched" open1l1gs supportive of residential or office use. Buildings are placed at or near the public right-of-way to meet the adjacent side\valk and greet and pedestrian. This pattern continued on as an "implied tradition" of development for nearly 80 years. .\Iore recent automobIle oriented development patterns have moved away from this pattern due to the mobility the car provides, relatively low costs of fuel and a general availability of lower cost, undeveloped land. \\'e are see1l1g a return to more traditional neighborhood and downtown development patterns as demographics, energy costs and lifestyle preferences point to a desire and/or need for this pattern. 2-3 2.2.2 DEFINITIONS "Base", "Middle", and "Top" Downtown Prior Lake will contlnuc to ,upport the tradition of building buildings that support a walkable, traditional downtm,\;n, This tradition of designing buildings with a "basc", ""lniddle'" anu '':t()P~~ enCOUrllges tTIofe active street level use and the creation of well proportioned, attractive buildings that add to the overall character and consistency of the downtown. Bey' llId c< .mplYlfIg with applicable heIght restrictions and/or recommendations, building design on each redevelopment site or development parcel, where new construction is to occur, is also required to incorporate particular horizontal divisions within the vertical building wall (facade). Such divisions support the concept that buildings in an urban context have, in general terms, three vertical divisions: "Bases", ";\fiddles", and "Tops". Specific architectural features and accents may extend above the "Top" of the building to add \'isual interest and spatial impact. "Building" _\ "building" is any structure '.yithin a development parcel for the shelter, support, or enclosure of persons or property. 2.4 Base Middle Top Complete ..-------- ~~ --- ...--JI_ - -- - - .. - - - / I-- - !- - - ~ ..--JI__ .. .J a o or O[ o JJfDdqOJ [OrODO(t1J ~R~~J[JD_O_I ~-8~-g818-- l_u~JDO,~,D_ -- ~D--_ - --r---1 iDDDD[] 0,000'0 ........._..._._...._. ....~._.__ ----..__ ....,'" ..........---............~. _.~_.---_ ~ I __ Void (lbO'u ~olid 34~';o Void 48tlll Solid 520'0 r'~~1 [JODDD\ _..4 ._ ... .'- ~. -_ _ _ _ _ - _ _.....- ".1 [OliClD 0 0 j "'_' .....,',__~. ~_ -______1 " ~ I DID ODD r -:: ~---- --- --- m_ LD10llOO Void 40% Solid 60.'0 ~~-~-"~,~- I OIL..; LJ ul 0 ------...... ---.-----'..-- 00000 ------------- DOOOO ------------ L.D~E DID ~I Void 250'0 Solid 75~'o The comparative effects of various "solid" to "void" ratios for fenestration "Facade" The "facade" is any exterior face of a building.

The intent is to create an area that achieves its own Hkntity ,dllle, at the same rime, supp' ,rring and enhancing rhe goals of rhe Pri"r Lake 2030 plan. In general, the achievement of these two goals invokes: 1) An Emphasis on Street Oriented Development The urban street network - the building defined pedestrian and vehicular spaces of the city - is recognized as a primary element of urban structure and organization. The street focuses activities, defines circulation and provides continuity with the surrounding community. Main Avenue should be the focus and emphasis of all development for the foreseeable future. 2) Getting the Parking Right The Cin' of Prior Lake mllsr focus on meerll1g the needs"f the surrounding land lIses by creating flexible parking standards that seek an optimal number of parking spaces. Private and Public development must respond with development specific solutions that acknowledge and support overall downtown goals. The response will be different on Main Avenue than it will be on Dakota, Pleasant, "\rcadia or other areas off of :\lain Avenue. Development must use one of four techniques: ":\love it", "Share it", "Deck it", and/or "\X'rap it" to create the right solution for each specific area. In all cases parking should have limited visual impact on the continuity and character of :\1ain Avenue. 3) Creating a Vital Mix of uses A healthy and robust downtown requires a compact and diverse set of uses geared towards users of all ages. Specifically this may include retail, commercial and professional services, offices, housing, dining, civic uses, education, arts and recreation, ,\ balance should be sought that complements and enhances the other uses and provides for activities 24 hours a day, 7 days a week. 2.4.2 PRIMARY USE PATTERNS The primary emphasis of any development or rede\'elopment should be focused on Main c\venue. Primary consideration should be given to mixed use development with active ground floor uses combined with residential or office uses stacked above. 1) Ground Floor Retail and Commercial Services Ground floor retail and commercial services should be oriented primarily towards Main _-\venue. Primary building entries, business entries and storefronts should have primary frontage on ;\Iain "'\venue. Curb cuts for accessing parking and service areas should be minimized or preferably avoided on "lain i\,Yenue. 2) Residential "Stand Alone" residential units or residential units stacked over commercial uses are desirable along J\lain Avenue. The orientation of portions of residential development may be positioned perpemlicular to "lain Avenue facing cross streets, internal c< ,urn.ards or internal parking court,. 3) Parking Off street parking that supports uses on Main Avenue should always be located behind or under the buildings fronting on Main ,-\venue. 2-9 2 2: 1- Creates a sense of enclosure and an "outdoor room". 3:1- I Sense of enclosure is minimal but perceptible. ) 4: I- I Sense of enclosure does not exist.

This condition creates the perception of an "outdoor room" that is framed by the facades of abutting architecture. This enhances and supports the pedestrian environment and creates a backdrop for the collective experience on the street. Creating a downtown precinct !vlain Avenue is today a two way street with diagonal parking on each side. The curb to curb dimension is approximately 60' with +- 10' sidewalks on each side. This creates a dimension of roughly 80' between building Llces. To create a desirable pedestrian environment, building heights must be no less than 26' high with a desirable height of 40' or more. This can be achieved with 3 or 4 story developmt:nr. 2.4.4 GROUND FLOOR USES AND ARCHITECTURAL EXPRESSION New buildings with ground floor retail, commercial or service uses should have open and transparent ground floor facades to be inviting to pedestrians. The dominant portion of the facade should create vertical plane that frames the public realm, Ground floor residential uses should reinforce the street edge but the dominant portion of the facade may be set back up to 10' from the right-of-way. The building should address the sidewalk by introducing stoops, stairs, walls, planters and overhangs that come out from the primary facade to create a secondary layer abutting the Right-Of-V'v'ay k L)()(n; ;,], Jfrtfl .fed/oll di(~grt111J ;j,!/lJ/J{/!if~g d{uired /1/'(/-il/('(//I/(;/ 1','\1IrCJ/io!/ lJI/Nre COJI/II/creta!.

The General Plan suggests a long term street face and block pattern that development should seek to reinforce. Buildings set on, or close to, the public right-ot-way on most block faces e....... ,.~ Buildings held back 0 right-of- way +-30 feet on CH 21, east ot Main Avenue N; HWY 13 This diagram suggest building faces and footprints that reinforce streetscape definition by rey'uiring the vast majority of building faces to be Hush with the sidewalk and the right-of-way edges. Exceptions are generally limited to the major passages between structures linking to open spaces or pedestrians ways; or as a last resort if unavoidable, access to parking. A larger setback is proposed on CH 21 between Highway 13 and Main Avenue. This area should become a greenway that creates a foreground for new development on the west side of CH 21. 2- 12 "/ I' /~k/ ..- // ~-J / 'j )j /"/- _~~ t ~/ I r / .I --, / -\~ \ " ,\;~~ J _~ . -<- \} -, ......., I I / / j/ Sketch illustrating arrival sequence to Main Avenue fro~the east looking towards J\1ain .\venue from Highway 13.

This spatial arrangement allows for the recognition of J\Iain Avenue as a street and space perpendicular to CH 21. 2- 13 SECTION 3 Building Design Guidelines 2-15 3.1 Building Heights 3.1.1 LONG TERM FRAMEWORK The current height of downtown buildings varies from 1 story to 3 stories. The long term vision for the downtown is to create a cohesive and unique assembly of buildings and uses with a maximum height of approximately 57 feet comprised ()f 4 stories. Architectural features may exceed this height where areas of emphasis are necessary such as the "gateway" intersection of CH 21 and Main _\venue. The development and enhancement of the downtown will be an incremental process. Each development and building project will have the opportunity to support and enforce the overall framework by complying with the recommended height guidelines. It is important that new projects are undertaken with a long term view towards the success of downtown Prior Lake and an under;;tanding of how each projeCT adds or detracts from this success, 2- 16 3.1.2 BUILDING HEIGHTS The currenr height of downtown buildings varies from 1 story to 3 stories.

Such divisions support tht: concept that buildings in an urban context ha\'t:, in general terms, three vertical divisions: "Bases", "Middles", and "Tops". The Top may also itself contain a division called a "Cap". In downtown Prior Lake, the specifics of these divisions are intendt:d to relate to the primary stret:t frontage on Main Avt:nue and secondary and tertiary frontage of perpendicular streets and nearby parallel streets. Each division will be distinguished from the adjacent division. The following requirements will apply to the design of the building wall: 1) Each "Base" \vill be composed of the first floor or the first two floors of the building. 2) Each "Base", in it's entirety, will be designed to give the appearance of greater height than any single floor in the "Middle". 3) The "Middle" will be between the "Base" and the "Top". 4) The architectural treatment of the "Top" will be designed to create a sense of distinctly finishing the dominant architectural theme of the ":'I.Iiddle" of the building. This architecrural finish may be accomplished by changes in the window rhythm, change in the apparent floor height, setback, or use of alternate materials, or a combination of these elements. 5) Setbacks extending the horizontal length of the facade will typically not occur in the "Base" and "Middle" divisions. The "Top" section however, may be designed so that it is set back from the "Middle" division. 6) Distinctive corner and entry treatments may differ from the "Base", "Middle" and "Top" guidelines of this section in order to enhance the building facades and overall architectural composition. 7) Roof elements such as elevate lr overruns, mechanical penthouses and roof stair access constructs will be screened with fence or wall enclosures which, in their configuration, materials, coloration and surface design are compatible with the exterior wall design bdow. 8) Bases should be designed to accommodate signage in an orderly and attractive manner.
