(1) Lot area and width standards. The following standards shall apply to all lots within the Shoreland Overlay District, provided that the resulting total development density in the shoreland area does not exceed the total city-wide shoreland density allowed based on state shoreland standards. The city, in its evaluation of any development, shall evaluate the proposed development in light of the development capacity of the city-wide Shoreland Overlay District. Where the requirements of the underlying zoning district are more or less restrictive than those set forth herein, the more restrictive standards shall apply.

(c) Additional special provisions.
1. Only land above the ordinary high water level of public waters and outside existing watercourses can be used to meet the lot area standards.
2. The shoreland lot width standards must be met at both the ordinary high water level and the building setback line.
3. All single-family, two-family, triplex, quadraminium, townhouse, commercial and industrial subdivisions must provide a grading and drainage plan for review and approval of the city engineer and Rice Creek Watershed District. The grading and drainage plan shall include:
a. Compliance for the impervious surface standards of the respective zoning district;
b. The subdivision or lot development shall provide for the collection and treatment of storm water in compliance with the Lino Lakes local storm water management plan if determined that the site improvements will result in increased runoff directly entering a public water. All grading and drainage plans shall require review and approval by the city engineer and the Rice Creek Watershed District;
c. Measures to be taken for the treatment of storm water runoff and/or prevention of storm water from directly entering a public water. The measures may include, but not be limited to the following:
i. Appurtenances as sedimentation basins, debris basins, desalting basins or silt traps;
ii. Installation of debris guards and microsilt basins on storm sewer inlets;
iii. Use where necessary, oil skimming devices or sump catch basins;
iv. Direct drainage away from the lake and into pervious, grassed yards through site grading, use of gutters and downspouts;
v. Construct sidewalks and driveways of partially pervious raised materials such as decking which has natural earth or other previous material beneath or between the planking;
vi. Use grading and construction techniques which encourage rapid-infiltration; for example, sand and gravel under impervious materials with adjacent infiltration swales graded to lead into them; and/or
vii. Install berms, water bars or terraces which temporarily detain water before dispersing it into pervious area.
4. Impervious surface coverage of lots must not exceed the following percentages of lot area:
NE | RD | GD | R | |
Single-family | 30% | 30% | 30% | 30% |
Two-family/duplex | 30% | 30% | 30% | 30% |

5. Medium density residential, commercial and industrial structures, parking areas and other facilities shall be treated to reduce visibility as viewed from public waters and adjacent shorelands by vegetation, topography, increased setbacks or color, assuming summer, leaf-on conditions. Vegetative and topographic screening shall be preserved, if existing, or may be required to be provided.
6. Accessory structures and facilities shall meet the required principal structure setback and shall be centralized.
7. Multiple-family developments shall contain open space meeting the following criteria:
a. At least 35% of the total development area shall be preserved as open space;
b. Dwelling units or sites, land covered by road surfaces, parking areas or structures are developed areas and shall not be included in the computation of minimum open space;
c. Open space shall include areas with physical characteristics unsuitable for development in their natural state and areas containing significant historic sites or unplatted cemeteries; and
d. The shore impact zone, based on normal structure setbacks, shall be included as open space. At least 50% of the shore impact zone area of existing developments or at least 70% of the shore impact zone area of new developments shall be preserved in its natural or existing state.
8. Residential subdivisions exceeding those permitted by the lot area standards of this section can only be allowed if designed and approved as a residential planned unit development under § 1102.13 of this chapter.
(2) Placement, design and height of structures.
(a) Placement of structures on lots. When more than one setback applies to a site, structures and facilities must be located to meet all setbacks. Where structures exist on the adjoining lots on both sides of a proposed building site, structure setbacks may be altered without a variance to conform to the adjoining setbacks from the ordinary high water level, provided the proposed building site is not located in a shore impact zone. Structures shall be located as follows.
1. Structure and on-site sewage system setbacks (in feet) from ordinary high water level.
Classes of Public Waters | Structures | Sewage Treatment System | |
Unsewered | Sewered
| ||
Lakes | |||
Natural environment | 150 | 150 | 150 |
Recreational development | 100 | 75 | 75 |
General development | 75 | 50 | 50 |
Rivers and streams | 100 | 50 | 75 |
* One water-oriented accessory structure exclusive of one dock and lake access individual lot, designed in accordance with division (2)(b) below of this chapter may be set back a minimum distance of ten feet from the ordinary high water level.
2. Additional structure setbacks. The following additional structure setbacks apply, regardless of the classification of the water body:
Setback From: | Setback (in feet) |
Top of bluff | 30 |
Unplatted cemetery | 50 |
Right-of-way line of federal, state or county highway | 40 |
Right-of-way line of a town road, public street or other roads or streets not classified | 30 |
3. Uses without water-oriented needs. Uses without water-oriented needs must be substantially screened from view from the water by vegetation or topography, assuming summer, leaf-on conditions.
4. Exceptions to structure setback requirements. Accessory structures may be located in the front yard of lakeshore properties upon approval of a riparian lot variance.
(b) Design criteria for structures.
1. High water elevations.
a. Structures must be placed with the lowest floor three feet above the (OHW) ordinary high water level in accordance with the local water management plan for the City of Lino Lakes.
b. Water-oriented structures may have the lowest floor placed lower than the elevation determined in the local water management plan if the structure is constructed of flood-resistant materials to the elevation, electrical and mechanical equipment is placed above the elevation and, if long duration flooding is anticipated, the structure is built to withstand ice action and wind-driven waves and debris.
2. Water-oriented accessory structures. Each lot may have one water-oriented accessory structure not meeting the normal structure setback in division (2)(a) above of this chapter if this water-oriented structure complies with the following provisions:
a. The structure or facility must not exceed ten feet in height, exclusive of safety rails and cannot occupy an area greater than 250 square feet. Detached decks must not exceed eight feet above grade at any point;
b. The setback of the structure or facility from the ordinary high water level must be at least ten feet;
c. The structure or facility must be treated to reduce visibility as viewed from public waters and adjacent shorelands by vegetation, topography, increased setbacks or color, assuming summer, leaf-on conditions;
d. The roof may be used as a deck with safety rails, but must not be enclosed or used as a storage area;
e. The structure or facility must not be designed or used for human habitation and must not contain water supply or sewage treatment facilities; and
f. Within the shoreland areas of general development and recreational development waterbodies, water-oriented accessory structures used solely for watercraft storage, and including storage or related boating and water-oriented sporting equipment, may occupy an area up to 400 square feet provided the maximum width of the structure is 20 feet as measured parallel to the configuration of the shoreline.
3. Stairways, lifts and landings. Stairways and lifts are the preferred alternative to major topographic alterations for achieving access up and down steep slopes to shore areas. Stairways and lifts must meet the following design requirements:
a. Stairways and lifts must not exceed four feet in width on residential lots. Wider stairways may be used for commercial properties, public open-space recreational properties and planned unit developments;
b. Landings for stairways and lifts on residential lots must not exceed 32 square feet in area. Landings larger than 32 square feet may be used for commercial properties, public open-space recreational properties and planned unit developments;
c. Canopies or roofs are not allowed on stairways, lifts or landings;
d. Stairways, lifts and landings may be either constructed above the ground on posts or pilings, or placed into the ground, provided they are designed and built in a manner that ensures control of soil erosion;
e. Stairways, lifts and landings must be located in the most visually inconspicuous portions of lots, as viewed from the surface of the public water assuming summer, leaf-on conditions, whenever practical; and
f. Facilities such as ramps, lifts, mobility paths for, physically handicapped persons are also allowed for achieving access to shore areas, provided that the dimensional and performance standards of division (2)(b)1. to (2)(b)5. or complied with in addition to the requirements of Minnesota Regulations, Chapter 1340.
4. Significant historic sites. No structure may be placed on a significant historic site in a manner that affects the values of the site unless adequate information about the site has been removed and documented in a public repository.
5. Steep slopes. The Zoning Administrator must evaluate possible soil erosion impacts and development visibility from public waters before issuing a permit for construction of sewage treatment systems, roads, driveways, structures or other improvements on steep slopes. When determined necessary, conditions must be attached to issued permits to prevent erosion and to preserve existing vegetation screening of structures, vehicles and other facilities as viewed from the surface of public waters, assuming summer, leaf-on vegetation.
(c) Height of structures. All structures shall not exceed 36 feet in height, except churches and nonresidential agricultural structures.
