Seattle City Light, October 1996

This village is located in City Light's Southwest forecast area, which has a total capacity 427 of megawatts.

Water

This village is located in the 316 pressure zone. Water is supplied from the Cedar River supply. Storage is provided by the Beacon Reservoir (Beacon Ave. S & S Spokane St.) and Trenton Standpipes.

See map for system locations. (Utilities Figure A4, Comprehensive Plan Appendix).

Beacon Reservoir: 61 million gallons

Supply mains were constructed primarily before 1949. Pipes are primarily of cast iron. Portions of the system in the Southwest Harbor area were constructed after 1979.

It is usual for facilities in industrial areas to be sized to accommodate the larger needs of industrial water users.

Seattle Water Department, October-November, 1996

In this pressure zone, elevations range from 10-60 feet above sea level; static water pressure ranges from 111-133 pounds per square inch.4 Minimum pressure in this area is considered very good.

Soils could be subject to liquefaction in seismic events.

Drainage & Wastewater

About half of this center is served by a partially separated system and half by a combined system, with small areas in the southern portion of the Center served by a separated system with a ditch & culvert stormwater system.

The southeastern portion of this Center is located in the Norfolk Drainage Basin, which covers about 672 acres. The existing drainage system flows through two small natural wetland areas and discharges to the Norfolk Outfall into the Duwamish River.

The southwestern portion of this Center is located in the South Park basin, which has two areas with distinct characteristics: 1. west basin steep and moderately wooded; and 2. east basin very flat and highly developed. No single, well-defined drainage corridor exists for this basin. Drainage occurs through several small corridors which eventually discharge to the Duwamish River. Runoff from the east drainage basin either flows overland to the Duwamish River at various points or enters the sewer system.

See map for system locations. (Utilities Figure A5, Comprehensive Plan Appendix).

With Partially Separated systems, about 15% of the stormwater enters the sewer system, with the remaining 85% diverted to the storm drain system. Capacity of the Partially Separated systems in this area is considered adequate.

With Combined systems, existing sewage flows constitute about 5% of pipe capacity, with the remainder for stormwater flows. Capacity of the combined systems in this area is considered adequate.

In areas with Separated systems and storm drains, systems are sized for full zoned development and capacity is considered adequate.

In areas with Separated systems and ditch & culvert drainage systems, sewage systems are sized for full zoned development and capacity is considered adequate. Drainage systems in these areas occasionally lack adequate capacity. CIP projects to provide additional capacity are part of a 15 year program in the City's adopted Comprehensive Drainage Plan.

Occasionally, sewer rehabilitation projects in the 6-year Capital Improvement Program are completed which sometimes enhance the system capacity in an area.

Seattle Drainage and Wastewater Utility, November 1996

Combined Sanitary/Stormwater System: A system where all sanitary and storm wastewater is carried through the system in one sewer pipe.

Partial Separation System: A system where the water from street and major parking lot drainage is collected and transferred in one pipe or ditch and culvert system, and the other surface wastewater such as that from roof drains is carried with the sanitary sewer in a sewer pipe.

Separate Sanitary and Stormwater System: A system where the sanitary wastes are transferred in one pipe, and roof and street runoff is carried in a separate pipe or through a ditch & culvert system.

The Fire Stations that serve this M/IC have the following response times

Station Emergency medical calls Fire calls

SFD 5 2.63 minutes 3.61 minutes

SFD 10 2.99 minutes 3.71 minutes

SFD 11 4.15 minutes 4.71 minutes

SFD 26 3.51 minutes 4.99 minutes

SFD 29 3.77 minutes 4.14 minutes

SFD 36 4.27 minutes 5.01 minutes

Except for station #36, all response times meet industry standards and are expected to for the next six years. Station #36 is located very close to the center, therefore response times to calls for service within the center should be well below the station average and are expected to remain so for the next six years.

Police

None

Additional space may be required.

Patrol units are allocated around-the-clock based on calls for service. Location and size of facilities are not critical to service provision. The new West Precinct facilities nearing completion will accommodate this precinct's facility needs. Minor facility modifications for other precincts will occur as needed and funded.

Electricity

None

A 4th transformer and switchgear bus-section will be added to the Duwamish Substation to increase capacity in this forecast area

Electrical demand from this M/IC is estimated to increase by 7.8 annual average megawatts and 12.6 megawatts in a peak hour in 6 years.

This village is located in City Light's Southwest forecast area. In 6 years, capacity in this forecast area will be 427 megawatts, and demand is expected to be 398 megawatts. In 20 years, capacity in this forecast area will be 547 megawatts, and demand is expected to be 471 megawatts. In both years, capacity is more than adequate to meet demand.

Water

None

None

Current peak day demand estimate: 13.0 million gallons per day (mgd). Peak day demand estimate in 6 yrs: 13.9 mgd or 6% increase. Peak day demand estimate in 20 years: 15.2 mgd or 17% increase. The supply and distribution network is in generally good order and appears to be adequately sized to accommodate demand through 2002.

It is usual for facilities in industrial areas to be sized to accommodate the larger needs of industrial water users. Current job projections indicate that increases in peak day water use could be met by existing networks. As individual redevelopments proceed, the infrastructure will need to be reviewed to eliminate any localized problems.

Drainage and Wastewater

No new facilities are expected because of new growth.

The Drainage Control Ordinance requires on-site detention of stormwater runoff associated with new development or significant redevelopment. Limiting the rate of stormwater runoff from these sites more than offsets the increases in sewage flow from increased population density. The net effect of new development/redevelopment in this area will be a decrease in the peak rates of flow during storm events.

Depending on the concentration of actual development, it is possible that isolated sewer capacity improvements would be needed.

For Partially separated systems, wastes from growth will constitute small incremental flows that are not likely to exceed capacity. With Combined systems, existing sewage flows constitute only about 5% of pipe capacity, and wastes from growth will constitute small incremental flows that are not likely to exceed capacity. On-site detention requirements for new growth will address the adequacy of the drainage systems for these areas.

In areas with Separated systems and ditch & culvert stormwater systems, sewage systems are sized for full zoned development; capacity is considered adequate to serve growth. Drainage system improvements in the Comprehensive Drainage Plan and on-site detention requirements for new growth will address the adequacy of the drainage system for this area.

See the Norfolk Study and the South Park and Norfolk Basin Plans in the 1995 Comprehensive Drainage Plan Update, Seattle Drainage and Wastewater Utility.

The volume-to-capacity (V/C) ratio is an indicator of congestion. The table above shows existing V/C ratios and projections of V/C ratios for a typical evening peak hour in 2010 for all arterials in the Duwamish Manufacturing and Industrial Center. The existing V/C ratios are estimated from traffic counts collected in 1992 through 1995. Compare existing V/C ratios to the 2010 forecast to see the potential change over time.

The V/C ratio can be used to identify areas where neighborhood or citywide transportation plans could encourage changes in travel behavior (e.g., mode, time of travel, destination) or improve operation of the street (e.g., by changing signal timing and the like). The capacity of a street is not a fixed number of vehicles that can never be exceeded. Rather, it is a relative measure of traffic flow.

Arterial segments with a V/C ratio exceeding 1.0 now or possibly in the future might warrant attention in a neighborhood plan. High V/C ratios may be tolerable if the result is to shift people into other modes, or is a result of the development densities necessary for a vital urban village.

Existing conditions: The V/C ratio on the First Avenue South Bridge is 1.6 northbound and 1.3 southbound. The westbound on-ramp from S. Michigan St. to the bridge has a V/C ratio of 1.0. East Marginal Way S. from the south city limit to S. Michigan St. has a V/C ratio of 1.1. The VC ratio on the westbound West Seattle Freeway west of Alaskan Way is 1.1. The Alaskan Way Viaduct also has a V/C ratio of 1.1 southbound between the 1st Ave. S. ramps and East Marginal Way S. The V/C ratio in the northbound direction on the viaduct is 1.0. Other streets in the manufacturing/industrial center with a V/C ratio of 1.0 include 1st Ave. S. between S. Spokane St. and Royal Brougham Way, S. Michigan St. between E Marginal Way S. and Carleton Ave. S., and S. Hardy St. between Airport Way S. and S. Albro Pl.

The Alaskan Way Viaduct is a state highway (SR 99) with limited access starting at S. Spokane St. and continuing north through downtown Seattle along the waterfront. SR 99 continues south of the viaduct as East Marginal Way, across the First Avenue South Bridge, and then southeast toward I-5. SR 509 is a southerly extension of SR 99 south of the First Avenue South Bridge toward Burien and Sea-Tac. The City of Seattle and Washington State Department of Transportation are constructing a second span parallel to the First Avenue South Bridge (SR 99) that will increase capacity and improve safety.

Other principal arterials in the manufacturing and industrial center include: 1st Ave. S., 4th Ave. S., Airport Way S., Alaskan Way S., East Marginal Way S., West Marginal Way S., S./S.W. Spokane St., Royal Brougham Way, S. Michigan St., Ellis Ave. S., S. Albro Pl, S. Hardy St., S. Cloverdale St., 14th Ave. S., and Delridge Way S.W.

Transit Priority Network streets in the manufacturing and industrial center include: Alaskan Way Viaduct, East Marginal Way from the Alaskan Way Viaduct to 1st Ave. S., First Avenue South Bridge, SR 509, 4th Ave. S., S. Michigan St., S. Spokane St. Viaduct, West Seattle Freeway, and Delridge Way S.W.

Future conditions: As a result of the new construction, the V/C ratio on the First Avenue South Bridge is projected to improve to below 0.8. North of the Michigan St. ramps, the capacity was assumed to remain unchanged, so the increase in traffic volumes (from existing) would result in V/C ratios near 1.2 southbound on this section. The V/C ratio on the northbound off-ramp to Michigan St./East Marginal Way is projected to increase to 1.1.

The V/C ratio on the Alaskan Way Viaduct is projected to increase to 1.1 northbound and 1.2 southbound. East Marginal Way S. would see an increase to 1.1 in the southbound direction. The V/C ratio on 1st Ave. S. between S. Spokane St. and Royal Brougham Way is projected to increase to 1.2 northbound and 1.3 southbound. North of Royal Brougham Way (both directions) and south of S. Spokane St. (southbound), the V/C ratio would increase to 1.0. The V/C ratio is also projected to increase to 1.1 on southbound West Marginal Way S.W. and eastbound S.W. Spokane St. between Harbor Island and East Marginal Way S.

In addition to those listed above, the V/C ratio is projected to increase to 1.0 on the following streets: Alaskan Way S. from S. Jackson St. to Royal Brougham Way, 4th Ave. S. from Royal Brougham Way to S. Spokane St., Airport Way S. from Royal Brougham Way to S. Hardy St., and the westbound Spokane St. Viaduct.

2 The nearest stations are listed; Fire and Emergency Medical Services are generally provided by the nearest station. In the case of larger fires, firefighting and medical resources are also dispatched from other stations. Aid units and fire engines are equipped to handle many medical emergencies; medic units are dispatched to serious medical emergencies.

3 Parks and Other Resources shown are inside the village or within 1/8 mile of the unadopted village boundary.

4 Minimum working pressure of 30 psi is the standard for new construction and 80 psi is the new standard for maximum pressure. Some areas of Seattle exceed the maximum and other areas have less than the minimum pressure.

5 The results of this analysis are not intended for measuring concurrency. Previous concurrency analyses contained in the Comprehensive Plan indicate that Level-of-Service standards will not be exceeded by the 20-year growth projected for this area (see Comprehensive Plan Transportation Element).
