ATM: This road is part of the minimum road system necessary for the management of NFS lands.

Travel Management Narrative: During timber harvest, motor vehicle use will be discouraged due to safety considerations. All motor vehicle use will be eliminated after timber harvest.

ROAD LOCATION: The initial 0.6 mile of planned road is on a decommissioned road prism. The remainder of the road is on moderate to steep side slopes with two short sections requiring full bench construction and end haul.

Site Specific Design Criteria

WETLAND AVOIDANCE: Road is located on existing fill from temporary road; avoid side casting or other placement of waste in wetlands where road passes through 0.23 mile of wetland (BMP 12.5).

AQUATICS/CRITICAL STREAM CROSSINGS: No Class I, II or III stream crossings. All other stream crossings are Class IV. National Core BMP Road-7 applies to all road stream crossings. A site survey will be conducted to determine the size and type of structure.

DRAFT Record of Decision

Appendix 2 ▪ 19

INVASIVE SPECIES: Low level infestation verify extent,prevent spread, and treat if feasible prior to closing out the road.

SOILS: Two road segments were identified for full bench construction and end haul: 15+ 05 for 160 feet and 25+47 for 340 feet. Recommend all areas with side slopes steeper than 55 percent have full bench construction and end haul (BMPs 14.3 and 14.7) No fine textured glacial deposits were identified in road recon, but landslide to the south originates in glacial till. Treat hillside as potentially unstable, during periods of high rainfall blasting operations should be suspended (BMP 14.6).

NO RESOURCE SPECIFIC REQUIREMENTS: Cultural Resources, Plants, Recreation, Scenery, Silviclture, Wildlife.

Maintenance Narrative: The initial 0.7 mile of existing road will require reconditioning. Work required may include: ditching, cleaning or replacing culverts, brushing, surface rock replacement, or subgrade repair. The entire 1.6 miles of road (existing and proposed) will be maintained as a maintenance level 1, or “inactive”, road following harvest activities.





ROAD LOCATION: The existing road crosses one Class II stream where the replacement of the structure is required. Fish passage will be provided with the new structure. The initial 0.4 mile of planned road is located on a decommissioned road prism. The remainder of the road is on moderate to steep side slopes.


AQUATICS/CRITICAL STREAM CROSSINGS: listed below require BMP 14.6 and 14.17. All other stream crossings are Class IV. National Core BMP Road-7 applies to all road stream crossings. A site survey will be conducted to determine the size and type of structure. All fish stream crossings will meet fish passage standards.

INVASIVE SPECIES: Low level of existing infestations; prevent spread, and treat if feasible prior to closing out the road.

SOILS: Road segments are on or adjacent to slopes mapped as having a gradient greater than 67 percent in the second growth stand. Lodgement till is mapped on the east facing hillside as road location leaves the second growth stand. Use full-bench and end-haul for approximately 200 feet on slopes over 50 percent gradient (BMPs 14.7 & 14.12). Rock walls or other structural features may be necessary to support cutbanks in this area (BMP 14.7). Road storage should include additional cross drains in this area to avoid concentrating water in any one hollow (BMP 14.9).

TRANSPORTATION: Reconditioning section all the culverts were removed and will require replacement. Approximately 14 Ditch Relief / Cross Drains, 9 Class IV, 1 Class II and 1 Class III Stream Crossings. The proposed road section has 2 Class III stream crossings.

Travel Management Narrative: During timber harvest, motor vehicle use will be discouraged due to safety considerations. All motor vehicle use will be accepted after timber harvest.

ROAD LOCATION: Road is located on gentle to moderate side slopes with a maximum side slope of 55 percent for approximately 70 feet. To minimize stream crossings, this road began after the stream crossing control at station 84+32 of road 50062. This resulted in the need to cross muskegs.


WETLAND AVOIDANCE: The road is located almost entirely in wetlands adjacent to the south fork tributary of Pats Creek; minimize footprint to the extent feasible, avoid side casting or other placement of waste in wetlands (BMP 12.5).

INVASIVE SPECIES: Rock quarry at beginning of road 50062 on State land is infested with reed canary grass and possibly other invasive plants. Ensure road is constructed of material from weed free source (quarry near rec cabin is weed free). Prior to closing road eradicate introduced invasive plant species.

Segments 2 to 4 will be dual designated as a NFS Trail and motorized OHV, 50 inches or less in width, will be accepted following harvest activities.


Appendix 2 ▪ 31

ROAD LOCATION: The initial 0.7 mile is on AK DNR lands and will require a right-of-way easement. The road is located on generally gentle to moderate side slopes, however full bench and end haul construction will be required in two sections. One Class II stream is crossed and a fish passage structure will be constructed. Multiple Class III streams are crossed requiring large culverts and small bridges.


WETLAND AVOIDANCE: A short segment of road crosses forested wetland; minimize footprint.

RECREATION: Open OHV, Rec, and subsistence.

SOILS: The road is located on fine textured glacial deposits with high potential for sediment generation and slope failure from MP 1.0 to the last Class III stream crossing. Geotechnical investigation would be conducted prior to road construction (BMP 14.3, 14.7 and 14.12-Road-2). Moderate slopes with potential for failure include the following.

State of Alaska land: MP 0.42 (100 feet) side slopes 45 to 55 percent; MP 0.5 (300 feet) side slopes 45 to 50 percent with 18 percent grade.

NFS land: MP 0.79 (910 feet) side slopes 48 to 55 percent; MP 1.13 (100 feet) side slopes 30 to 60 percent, incised channel below road; MP 1.6 (50 feet) side slopes 50 percent.

Pioneering equipment operating along this road should use caution and be prepared for slope failure.


Appendix 2 ▪ 32

Side slopes adjacent to the incised Class III streams will need immediate stabilization to prevent stream sedimentation; rock walls or other structural features may be necessary to support cutbanks in these areas (BMP 14.7). Use full bench construction with end haul at first and fourth stream crossings. Site specific erosion control measures will be designed depending on substrate exposed during construction (BMP 14.7), rock walls or other structural features may be necessary to support cutbanks (BMP 14.7). Ensure adequate cross drains are installed to avoid concentrating water on slide prone terrain (BMP 14.9), control erosion and disperse runoff away from streams (BMP 14.8).
