• ENVIRONMENTAL BOARD GUIDELINES The following guidelines were formulated by the Environmental Board. We suggest that these guidelines be distributed to developers who intend to initiate projects in Lino Lakes. By providing these guidelines, the Environmental Board hopes to assist developers to create a vision for their projects that is consistent with the environmental ethic of the City of Lino Lakes. Tree Preservation Trees are among the most visible components of the City's environmental landscape. Therefore, developers should make every effort to preserve them. Where trees must be removed, new trees should be planted on site, on an inch - for -inch diameter replacement basis. Before a development project can be scheduled for review by the Environmental Board, a tree inventory and preservation plan must be completed by the developer. Stormwater Infiltration and Treatment Given the extensive wetlands that are found in Lino Lakes, careful management of stormwater is essential. Therefore, project design should attempt to maintain on -site infiltration at pre - construction levels by maximizing infiltration of stormwater on the site and to reduce runoff into lakes and naturally occurring wetlands. When runoff into water bodies is unavoidable, stormwater should be directed over a vegetated surface via broad swales. The design should attempt to maximize the surface area over which the water flows. The total linear distance of this stormwater treatment train shall be at least 100 feet between the stormwater detention pond and the destination (ditch, lake, wetland). Environmental Context The City's environmental resources are distributed in a manner that is independent of property boundaries. Therefore, planning of open spaces and other environmental aspects of the project must consider the larger ecological context of the project's location within Lino Lakes generally, and within the greenway system specifically. Environmentally sensitive areas in close proximity to the project site should be identified from the City's ecological delineation map. Project design must attempt to use the buffers and open spaces (elements included in all projects) to establish corridors that will allow the open space network within a project to be connected to nearby open spaces of significant size. Impervious Surfaces One of the easiest ways to minimize the negative impact of development on our environmental resources and services upon which we depend, is to be conservative in the construction of impervious surfaces. Therefore, developers should be aggressive in their efforts to minimize the impervious surfaces in any development. For example, alternatives to asphalt and concrete parking areas should be considered. Similarly, where possible, developers should work with city staff to use narrower streets in their development projects.
