(A) Findings and purpose.
(1) Findings. The city finds that traditional turf grass lawns require large amounts of water, fertilizers and chemical pest controls to maintain. Using large amounts of water to maintain lawns threatens the city’s groundwater supply while fertilizers and chemical pest controls pollute our lakes, rivers and streams. Alternative landscape techniques have significant advantages over turf grass, specifically:
(a) Native vegetation requires less moisture, fertilizers, and pesticides and places less stress on the public’s water resources. Native vegetation also provides food and habitat to wildlife.
(b) Rain gardens filter and infiltrate stormwater, thereby protecting surface water from polluted runoff and recharging groundwater resources.
(c) Producing foods locally:
1. Increases local food security;
2. Addresses global warming by reducing fossil fuel use in transportation of foods; and
3. Addresses the obesity epidemic by insuring access to healthy, fresh foods.
(2) Purpose. The purpose of this section is to prohibit the uncontrolled growth of vegetation, while encouraging the planting and maintenance of native vegetation, edible landscapes, and rain gardens. There are reasonable expectations regarding the proper maintenance of vegetation on any lot or parcel of land. Providing standards regarding the maintenance of vegetation and encouraging diverse landscaping meets the following goals of the city’s comprehensive plan:
(a) Create and maintain attractive and safe neighborhoods;
(b) Restore the city’s native vegetation;
(c) Encourage the local food production system; and
(d) Protect and improve the city’s surface waters through increasing on-site infiltration in existing developed areas.
(B) Applicability. This section applies to all zoning districts.
(C) Landscape regulations.
(1) Plants allowed. Ornamental plants; native forbs and grasses; or vegetable and fruit bearing plants are allowed in the landscape area, but they must be planted pursuant to a design. The design must either be created by a professional landscape designer or be consistent with Model Community Soil and Water Conservation District (SWCD) standards.
(2) Restoration and establishment of managed natural landscapes. Restoration or establishment of managed natural landscapes is allowed pursuant to M.S. § 412.925. Restoration projects should be consistent with the Minnesota DNR requirements and guidelines.
(3) Managed natural landscapes on city-owned-boulevards/rights-of way may be allowed with the following conditions:
(a) An annual administrative permit is required for managed natural landscapes on city-owned-boulevards/rights-of-way and may be revoked if requirements are not met.
(b) The city, including Public Works Department, Fire Department and Police Department, or utility companies may need to access the area for roads, trees and utilities and are not responsible for any garden damage and are only required to restore the boulevard with turf grass seed or sod.
(c) Vegetation shall not be within 40 feet of intersections and 10 feet of alleys and driveways.
(d) Vegetation in the boulevard may have a maximum height of 4 feet.
(e) One foot of clear space is required from sidewalks and streets.
(f) Three feet of clear space is required from neighboring property boulevards.
(g) Three feet of clear space is required from fixed objects including, trees, fire hydrants, poles, signs, cabinets, and maintenance holes.
(h) Three-foot-wide access points shall be maintained every 15 feet to provide exit space for parked vehicles and access to the street and sidewalk.
(i) May not obstruct sidewalks, bus stops, signs, accessible parking spaces, loading zones, bikeways, snow plowing and clearing, public projects and reconstruction, emergency services (such as fire hydrants).

(m) Must comply with the provisions of the M.S. § 216D.01 et seq., Gopher State One Call Law.
(4) Locations encouraged. Native plantings and forbs are encouraged around ponds, wetlands and on slopes. Native plantings are also encouraged on landscape areas with slopes equal to or greater than 3 feet horizontal to 1 foot vertical (3:1).
(D) Rain gardens. Rain gardens should be constructed consistent with the document Rain Gardens: A How-to Manual for Homeowners, available from the Minnesota DNR.
(E) Maintenance of landscaping. The owner, agent, or lessee of any real property located within the city must provide regular weeding, pruning, and other maintenance of all plantings located on said private property including any managed natural landscapes on city-owned boulevards/rights-of-way. Plant materials which exhibit evidence of pests, disease, or damage shall be appropriately treated, and dead plants shall be removed or replaced. All native plantings must be maintained either by removing weeds, mowing, or city approved and permitted burning.
(1) Unattended vegetation. Every owner and responsible party who fails to keep private property clear of unattended vegetation is in violation of this section and subject to the remedies and enforcement specified herein.
(2) Prohibited vegetation. Every owner and responsible party is in violation of this section and subject to the remedies and enforcement specified herein if they fail to keep their private property clear of vegetation that:
(a) Presents a fire hazard;
(b) Attracts or harbors disease vectors;
