This memorandum reviews the elements of a proposed concept plan for a Planned Unit Development on a series of parcels adjoining the north side of 7t" Street, roughly between Fallon Avenue on the west and the Fallon Avenue roundabout on the east. The applicants include the developer and four primary property owners, including the "Malone" property (PID 1 55-01 1-000092), the "Jameson" property (PID 155-500-123300) the City of Monticello (PID 155-115-001011), along with a portion of a parcel currently owned by the St. Henry's Catholic Church (PID 155-115- 001010). Finally, a small corner of remnant park land is also included in the Concept Plan at the northeast corner of Fallon Avenue and 7t" Street. The parcels currently have a few scattered buildings, all of which would be removed. The applicant has been working with the State of Minnesota to "delist" the parcels and/or buildings from the National Register of Historic Places. The total PUD covers approximately 10.25 acres in area. Access to future development on the property is provided from Fallon Avenue via an internal private street. The applicant has made five specific requests as a part of the City's consideration of this project. A copy of that summary is included in this packet. A part of the applicant's request involves disposition of City property at no cost to the developer, and process aspects of the project's consideration. This memorandum focuses on land use elements and related site improvements. The proposed project consists of a 48 unit detached townhome development, a gross density of approximately 4.5 units per acre. This would be considered a medium density residential land use. The Comprehensive Plan designates much of the area for residential uses ("Places to Live"), with a portion guided for institutional uses ("Places for Community"). The Plan does not propose densities for residential development. As noted above, there are a series of parcels that make up the development site. The "Malone" and "Jameson" parcels are privately owned. The remnant park parcel at the corner of Fallon and 7t" Street is owned by the City by virtue of the dedication of that parcel for park purposes (that parcel actually extends across 7t" Street to include a small sliver of land between the street and the apartment building. A second city parcel extends from the Fallon Avenue roundabout to provide access into the interior of the area, particularly for the Jameson property which is otherwise landlocked (other than a private easement across the neighboring "Busch" property). This City parcel, while it fronts along 7t" Street and the roundabout, provides only technical frontage — the grade falls away steeply from the roundabout area, and presents challenges and expense for construction of a connection. As a result, the applicant has assembled the private parcels, and proposes to develop these along with the city parcels and land from St. Henry's church, utilizing a long single-entrance private street that gains access from Fallon Avenue on the west, extending for approximately 1,300 feet to the east, terminating in a cul-de-sac on what is currently the east end of the Jameson parcel. Detached townhome (or "patio home") lots are arrayed along both sides of this private street. For the project to proceed, there are a series of City land use approvals that will be required: o PUD Concept Review (the subject of this report). The project requires a PUD as it proposes to develop a series of parcels that will have 48 units on individual lots, common lot area, and a private street; Further land use approvals would include the following: o Comprehensive Land Use Plan amendment reguiding the proposed residential parcel from "Places for Community" to "Places to Live"; o Preliminary and Final Plats; o Development Stage and Final Stage PUD. o Rezoning to PUD, Planned Unit Development District; The current proposal is for a PUD Concept Plan review, which is not a formal zoning application, but is intended to provide the applicant an opportunity to get City feedback on a potential development proposal prior to more formal zoning review and the 1 extensive supporting materials that such reviews require. The Planning Commission and City Council will have the opportunity to review the project, ask questions of the proposer, and provide comment as to the issues and elements raised by the project. The neighboring property owners have been notified of the meeting, but it is not a formal public hearing. This memorandum provides an overview of the project and will serve as an outline for the discussion. No formal approval or denial is offered for a Concept Review. However, it is vital that Planning Commission and City Council members engage in a frank and open discussion of the project benefits and potential issues. The Concept Review process is most valuable when the applicants have the opportunity to understand how the City is likely to look at the project and the potential issues it presents. In this way, the subsequent land use and development details can be more finely tuned to address City policy elements. PUD Concept Review Criteria. The first stage consists of an informal Concept Plan review which is separate from the formal PUD application which will follow the Concept Review step. The Ordinance identifies the purpose of Planned Unit Development as follows- (1) Purpose and Intent The purpose of the Planned Unit Development (PUD) zoning district is to provide greater flexibility in the development of neighborhoods and non- residential areas in order to maximize public values and achieve more creative development outcomes while remaining economically viable and marketable. This is achieved by undertaking a process that results in a development outcome exceeding that which is typically achievable through the conventional zoning district. The City reserves the right to deny the PUD rezoning and direct the developer to re-apply under the standard applicable zoning district. PUD Concept reviews are to proceed as follows: (a) PUD Concept Proposal Prior to submitting formal development stage PUD, preliminary plat (as applicable) and rezoning applications for the proposed development, the applicant may, at its option, prepare an informal concept plan and present it to the Planning Commission and City Council at a concurrent work session, as scheduled by the Community Development Department. The purpose of the Concept Proposal is to: 1. Provide preliminary feedback on the concept plan in collaboration between the applicant, general public, Planning Commission, and City Council; 2 2. Provide a forum for public comment on the PUD prior to a requirement for extensive engineering and other plans. 3. Provide a forum to identify potential issues and benefits of the proposal which can be addressed at succeeding stages of PUD design and review. The intent of Concept Proposal review is to consider the general acceptability of the proposed land use, and identify potential issues that may guide the City's later consideration of a full PUD application. The City Council and Planning Commission meet in joint session to provide feedback to the developer, and may include an opportunity for informal public comment as they deem appropriate. Staff Preliminary Comments and Issues. For this proposal, the primary considerations evident at this point in the process include the following elements: i. Land Use. As stated above, the proposed project area is guided "Places to Live" (Residential) and Places for Community. The applicants propose the entire project area be guided to Places to Live, a residential category that would support the proposed detached single family development. ii. Cul-de-sac street. The proposal relies on a single-entrance private street of approximately 1,300 feet in length. All 48 units would utilize the single street access point on Fallon Avenue. The City's Subdivision Ordinance typically limits cul-de-sac streets to a maximum of 600 feet in length. One of the purposes of this standard is to limit the traffic volumes on residential streets. In a typical single family neighborhood, a 600 foot cul-de-sac would accommodate approximately 15 — 20 homes. The proposed project would generate up to three times the traffic along the street. Private streets are permitted under a PUD designation. iii. Pedestrian circulation. The applicants have identified two trail connections that extend to external properties. One is a longer route that extends from an internal cul-de-sac, generally along the route of the driveway easement across the "Busch" property. However, based on staff's understanding of the easement, no trail is permitted on that route — only the driveway that was to serve the Jameson house. The second trail extends from the end of the easterly cul-de-sac to a trail on the St. Benedict's residential property to the east. While this connection would be valuable to residents of this project and the St. Benedicts property, both trails serve private property and would not be accessible to the public— or each other unless the property owners agree. Instead of the trails proposed, staff would recommend a sidewalk along the length of the private street. This sidewalk would serve the residents of the development to gain access to a public street. The sidewalk would serve to 3 remove pedestrians from walking in the street—which as noted above, will be carrying significant levels of traffic. Moreover, the street is designed to be a relatively narrow paved surface. Pedestrians in the street would have no safe walking area without the sidewalk. Staff has suggested that the construction of the sidewalk, in specific the portions which provide access to a public system, could be considered an element that qualifies for a portion of the required park dedication. iv. Lot sizes and site planning. The applicants propose 50 foot wide lots, with detached buildings varying between 2 and 3 car garages. The plan details that garage setbacks would be 25 feet (although some are as little as 21.4 feet. Staff would suggest that 25 feet be maintained, as parking in the driveways for longer vehicles would interfere with snowplowing. The site planning presumes 6 foot side setbacks, leaving buildable area of 38 feet of width on most parcels. A three car garage will typically consume 30 feet or more of that width, although the applicants have not supplied architectural information on the proposed units. Rear setbacks are varied, and there appears to be little concern from a standard land use perspective, as the rear yards of the proposed units do not impact surrounding property. However, some of the setbacks are very shallow and would not accommodate the additions of decks or porches, additions which the City has seen can become problematic for townhome developments if not planned for initially. Staff notes also that one of the units in the center of the plat is situated without frontage or clear access to the street. This unit should be eliminated from the proposal. V. Park and Open Space. Based on the site plan and concept narrative provided by the applicant, the amount of open space is not addressed. As noted in the applicant's narrative materials, the applicant proposes that park dedication fees be waived, in exchange for construction of the trails shown on the plan. The applicant further notes that the connections could access the St. Henry's church property. However, this too is private property, and would not qualify as a park dedication credit. As noted, the illustrated trails are not feasible without additional agreement by other private property owners. Instead, staff has recommended a sidewalk along the private street. One area of uncertainty is a portion of the to-be-acquired St. Henry's church property that is not being developed, and is shown with hashed lines through it. The plan is not clear as to the intent of this area and would ask that the applicant clarify this portion of the concept area. 4 Staff notes that St. Henry's Church will need to verify the limits of its land conveyance as a part of the plat, and access to St. Henry's remaining parcel(s) will need to be clarified as a component of the development agreement. It is likely that a cross-access Conditional Use Permit will need to be processed concurrent with the Plat to resolve questions about frontage and access for the northerly St. Henry's parcel which is being subdivided in part for this project. vi. Parking and driveways. The plan shows two 5-space parking bays along the street to provide overflow parking. As a practical matter, the applicant should plan for one additional parking space per each 2.5 units, a total supply of approximately 20 off-street spaces. With the narrow street pavement dimension (26 feet), and the number of closely-space driveways from each of the proposed homes (not illustrated on the plan), there would be no other overflow parking than what is provided in the separate bays. Staff would recommend at least two additional 5-space bays be added to the plan. As noted, driveways are not illustrated on this plan. For the bulk of the project, there will be little conflict, and reasonable spacing. However, around the cul-de-sacs, driveways will be a significant issue as they converge — especially from 3-car garages — on the paved cul-de-sac area. Staff would recommend that additional spacing be provided between units on the cul-de- sacs, with at least 10 feet between driveway curb cuts. This can be accomplished with specific unit style and driveway orientation. Without this spacing, snow piling creates problems with visibility. vii. Fire access. The project should be reviewed by fire department officials for firefighting access. One staff suggestion is to reinforce the "trail" shown off of the easterly cul-de-sac to connect to the fire lane that circles the St. Benedicts building. Fire department comment on the feasibility of this idea is recommended. It should also be reviewed to ensure that the City would have access rights between this project and the fire lane on St. Benedict's property. viii. Existing park parcel. The applicant is asking that the City vacate the park interest in the remnant park at the corner of Fallon Avenue and 7t" Street, as it is proposed to be utilized for a portion of the western-most unit. This process can be a lengthy and expensive one which cost should be borne by the applicant. In addition, there are utilities within the parcel which will be required to be retained. These easements would limit the usability of the parcel. Other design options to work around the park parcel may be more easily implemented. ix. Building architecture. As noted, no building designs have been submitted with this concept. The City may wish to identify architectural elements that may be important for meeting the threshold of PUD design. Staff would recommend that the baseline standard be drawn from the T-N, Traditional Neighborhood building materials as a minimum. 5 X. Tree impacts and landscaping. There is a significant amount of tree cover on portions of the proposed development site. The plan does not detail the impacts on tree cover on the site. A tree survey will be required as part of the platting and PUD process. It would appear to be beneficial to shift the built area to the south if possible, toward the boundary with St. Henry's Church property to minimize tree impacts. Tree loss and replacement would be a factor in reviewing the eventual landscaping plans for the project. In addition, given the high visibility of the site, attention to landscaping should be given along the 7t" Street/Fallon Avenue roundabout area. xi. The City Engineer has provided a concept review letter detailing additional comments on this project. Summary. As noted, the Planning Commission and City Council provide comment and feedback to the developer at the Concept Review level. City officials should identify any areas of concern that would require amendment to avoid the potential for eventual denial, as well as any elements of the concept that the City would find essential for eventual approval. Specific comment should address the following potential issues- 1. Overall Land Use. 2. Density. 3. Cul-de-Sac Street Length. 4. Lot Configuration and Building Layout. 5. Park and Open Space Requirements. 6. Parking and Driveways. 7. Firefighting Access. 8. Existing Park Vacation. 9. Building Design and Materials. 10.Tree Impacts and Landscaping Requirements. 11.Engineering comments and recommendations. The notes listed above acknowledge that a significant amount of detail will be added as the project proceeds to a more advanced stage of review. As noted, the applicant has made five specific requests as a part of the City's consideration of this project. A copy of that summary is included in this packet. These items are subject to Council feedback and direction. The waiver of various land costs and development costs is a matter of legal and policy consideration for City Council review. Staff does not recommend waiving park dedication requirements, but it is common to credit constructed improvements (such as trail) where the improvements show benefit to the City's park and trail system plans and objectives. As noted initially, this memorandum reviews the land use and site planning elements of the request. The City Council should provide direction, either as a part of this joint 6 session or in a separate proceeding, regarding the public finance aspects of the request, although no formal decision can be made as part of the concept review. The City Council will likely be asked to participate formally in the plat and land use process as a property owner, and should provide direction to the applicant on any items requested as part of that consideration.
