Louisville Mill Site Redevelopment Project — Preliminary PUD and Plat Submittal Dated 04 103.'14 This Project will require a Preliminary and Final Subdivision Plat, and Preliminary and Final PUD approval for modification of commercial structure(s), construction of new structure(s), parking, and site development. Once the Preliminary Plat is approved and Lot 2 legal description can be described, the application for Landmark Designation of the Grain Elevator would move forward. A Landmark Alteration Certificate /rehabilitation plan will need to be approved by the Historic Preservation Commission, (Planning Commission as par of PUD review), and City Council. Site is within the 100 -yr regulatory flood plain. A Floodplain Development Permit will be required. It is understood that the City of Louisville is currently investigating floodplain mitigation which may affect the 100 -yr floodplain in this area with a CLOMR/LOMR through FEMA. Current design is for the new building on Lot 3 with a FFE above the Flood Protection Elevation, & floodproofing for the basement. Generally, the redevelopment proposed would include the following new and existing building areas, and would provide 65 parking spaces on site to meet the zoning requirements for this district. We intend to seek an extension of the leased railroad ROW for 13 additional parking spaces north of the existing leased ROW as indicated below and on the site plan. We also have the potential to reduce the main floor area of the Mill Site building to provide some tuck -under parking for an additional 5 -6 spaces, depending on tenant requirements for that area. We are seeking approval of an alternate parking plan as indicated for Outlot `A' which would yield an additional 9 spaces. We would like to preserve this flexibility for the future in the event that there are circumstances that would require us to provide this additional parking on site. We have also included 13 small car spaces on Lot 3, and 5 small car spaces on Lot 1, using standards that are used in Boulder and elsewhere on the front range. We feel it is appropriate to utilize our land resources prudently, and designing for a percentage of smaller vehicles will conserve land devoted to pavement, reducing heat island effect, and stormwater runoff.
