Hammer Industrial Subdivision, which is located at the southeast corner of 40t' Street and Kathryn Street in Springfield, Oregon. The proposal is to construct four buildings ranging from 6,099 square feet to 11,964 square feet with associated infrastructure. Applicant / Owners Representative A & O Engineering LLC Scott Morris, PE 380 Q Street, Ste 200 Springfield, OR 97477 (541)302-9790 scottmorris@ao-engr.com Owner Oakway Golf Inc. Attn: John Hammer P.O. Box 2266 Eugene, OR 97401 (541) 683-1166 Project Location Address: No Address Assigned Tax Lot: 17-02-30-44 T.L. 300,400 Existing Use of Site The project site is currently vacant of any buildings. There is an existing joint driveway to serve the Aramark Development at the southeast corner of Lot 7 in an existing joint access easement. Proposed Use The applicant is proposing to construct four multi -tenant buildings with associated infrastructure. There is not an identified tenant. There is one proposed loading dock (truck well) to serve the development on the west side of building one. There will be a shared trash enclosure within building three of lot 8 which serves all of lot 8. Lot 7 will have a shared trash enclosure within building one which will serve all of lot 7. The locations of these trash enclosures are shown on the site plans. The site will be accessible through existing entrances on the north side of Lot 8 (Kathryn Street) and the southeast corner of lot 7 as shown on the site plans. The proposed site is within the Mid -Springfield Development Plan. Our proposed use is within the parameters of the Mid -Springfield Development Plan. Land Use The parent zoning of the property is heavy industrial. The land uses of the abutting properties are: North: Heavy Industrial - Existing industrial development East: Heavy Industrial - 40' Street - Lot 10 across street (vacant) South: Heavy Industrial - Heavy Industrial — Aramark - West: Low Density Residential - 36th Street The proposed project meets the land use requirements of the development code given the abutting land use zoning and uses. The setbacks required for the project are 10 feet from the property lines, which have been provided in the proposed project. Site Access There are two existing accesses to the site which were constructed during the PEPI project associated with the J.P. Hammer Industrial Subdivision. There is a joint driveway shared with Aramark to the south, on Lot 7. This access is proposed to remain, utilizing existing grading and drainage patterns. The second access is a curb cut on Kathryn Street adjacent to Lot 8. Grading The proposed site will be graded to direct stormwater away from the buildings and into nearby catch basins throughout the site. The remainder of the site will be graded to match existing drainage patterns as well as elevations of adjacent properties. Wastewater System The buildings are proposed to be served by a new wastewater pipe system that will plug into existing stubs adjacent to the lots as shown on the utility plan. The lines will be routed to serve each potential lease space individually and be extended to tie into the area drains proposed in the trash enclosure and loading dock. The trash enclosure area will be covered with the concrete base graded to be hydraulically isolated. The existing mainline and stubs from Industrial Avenue were constructed as part of the PER project related to the J.P. Hammer Industrial Subdivision. Floor drains tied to the wastewater system are proposed to be located just inside the building at each overhead door location. Storm Water Svstem The site is located in the J.P. Hammer Industrial subdivision which includes 3 +/- acres of detention ponds to serve all of the parcels. Lots 7 and 8 discharge stormwater runoff into these detention ponds. The post -construction peak stormwater runoff was found to be 1.73 cfs during a 10 -year, 24-hour storm event. The drainage systems for Lot 7 and 8 are outlined below: Paving across both lots is proposed to be graded towards catch basins, forming a collection of basin areas. See the basin map shown on site plans for more information. Within this basin map, basins 7, 11, 13, 14, and 15 will see the stormwater runoff be mechanically treated prior to discharge into the storm main connection on the east side of Lot 7. Stormwater runoff from basins 10 and 12, which are composed of the roofs of the buildings proposed to be built on lot 7, will be routed into the same pipe system as the mechanically treated stormwater runoff before being discharged into the same storm main connection for Lot 7. The basin areas 1, 2, 3, 5, 8, and 9 will instead be vegetatively by flowing through a drainage system into the proposed stormwater planter on the northeast corner of Lot 8. From there, the stormwater will be treated prior to discharge into the storm main connection on the north side of the northeast corner of Lot 8. Basin areas 4 and 6, which are composed of the roofs of the buildings proposed to be built on Lot 8, will be routed around the stormwater planter to discharge directly into the same storm main connection for Lot 8. Water System The proposed water system is to install individual domestic water meters on the east side of the building, where the existing water line is located in a public utility easement. Both lines will then be routed through approved backflow systems and will be routed to separate portions of the proposed building. There will also be a %" branch line that will be extended to the trash enclosure to provide water for a yard hydrant and to prime the trap for the area drain. There are existing fire hydrants located north and south of the property. There is an existing hydrant on the north side of Olympic Street at the intersection with 40" Street (approximately 197' north of building). There is another hydrant located on the west side of 40� Street which is located approximately 209 feet south of the building. A separate sprinkler system for the building is not proposed. The final design of domestic water lines will be completed during the building permit process. Site Lighting The proposal is to install recessed downward facing TWR1 LED lighting on the exterior of the building, directed down to light the sidewalk and pavement areas adjacent to the structure. Pole lighting locations are shown on sheet C-3.0 with fixture details on sheet C-6.0 Photometric analysis is included with this submittal and shows no light trespass across exterior property lines. Landscape We are not removing more than 5 trees, therefore no tree removal permit is required. The planting plan for the site (including stormwater facilities) are outlined on sheets LA -1 and LA -2 of the plan set. The planting in the stormwater facilities meet the requirements outlined in the Eugene Slormwater Management Manual. The frontage along Kathryn Street and 40' Street has existing street trees that were planted during the public improvement project for the subdivision. Drinking Water Protection The proposed lot is located inside the 2-5 year time of travel zone and 5-10 year travel zone for drinking water protection. The area where vehicles will be driving will be paved. Storm water will be directed to two types of facilities to provide pollution control treatment prior to entering the existing detention pond system. Details are outlined on the plan sheets. Wetland protections notes are listed on Sheet 2.0 The stormwater planters will include 18 inches of soil media to meet the requirements in the drinking water protection area. Site Soils Malabon Urban Land Complex is generally described as hydrologic soil group C. The expected infiltration rate of this soil is approximately 0.5 inches per hour, which will allow the landscape areas to drain. The stormwater planter is lined, so no infiltration is planned for that facility. Franchise Utilities Franchise Utilities (Electric, Phone, Cable, Natural Gas) are located in the Kathryn Street and 40" Street rights of way adjacent to the project. Sheet C4 shows the preferred location for electric, phone, cable, and gas meters to serve the development. Franchise services will be designed by the providing utility companies during the building permit process. Building Elevations Preliminary building elevations for the building are shown on the architectural plan sheets provided by Rodd Hansen Architecture.
