TESC PLAN
1. Construction Access: We do not anticipate the need for a spalled exit from the site. We plan to do
the demolition in such a manner that our trucks can stay on hard surfaces at all times and thus avoid
track out from the site.
2. Protect Drain Inlet: We will place a CB filter bag in the existing on-site catch basin until the
Asphalt is removed, at which time we will plug the CB outlet to prevent any outflow of dirty water.
3. Sediment Controls: The black arrows on the attached drawing indicate the existing slopes. The
red arrows indicate how we will slope each area as our work progresses. As indicated at each
building,we will slope the adjacent area into the building footprint,which will be the lowest area
after the building and foundation are removed. Each of these will serve as a settling basin area
for any water to pond and infiltrate into the ground.
4. Conveyance Channel: Along the paved alley where the xxx are shown, we will construct a
shallow swale or place some type of a low barrier to prevent any potential runoff from this area
from flowing across the alley or down 256. This potential runoff will be diverted to the existing
pond behind the radio station building. We will utilize either sand bags, straw wattles, or some
hose/bags filled with sand or liquid for this barrier.
5. Planting: The owner will be planting grass in the radio station area as soon as the building and
existing landscaping are removed. The existing asphalt on the street side of the building is to stay.
Since the owner's plan is to start site prep and construction shortly after our work is completed, we
do not anticipate covering the site with anything once we are finished. If this plan changes, it will be the
owner's responsibility to implement any work needed.

WORK PLAN
1. Fencing: We plan to install temporary chain link fencing along the sidewalk across the
south side of the site. From there down the alley we will utilize orange construction fencing
since this will have to be moved often to allow access to the site for our trucks and equipment.
We will use this fencing and caution flagging as a warning bather for specific areas at each
building as needed. We will use the orange fencing for a limited distance only along the west
side of the site since it has an existing landscape buffer area and is not subject to normal
pedestrian traffic. On the north side of the buildings we will simply use caution flagging as
needed in the immediate area where we are working.
2. Dust Control: Once we start the actual building demo work and removal of concrete and
asphalt,we will keep our water truck on site so we can address any potential dust problems
quickly.
3. Work Sequence: We will start with either the radio station building or the house. The station
is set apart from the other buildings and could easily be removed at any time without impacting
the work that may or may not be in progress at the other buildings. The removal of this building
is largely dependent on when the asbestos abatement contractor can schedule their work to
remove the asbestos in the building.
The work sequence for the other 3 buildings will be to start with the house, first removing all
the salvageable items,then removing all the wood that can be chipped and the un-useable
materials that will go to a landfill. The concrete foundation, slabs, sidewalks and driveway will
be removed last. We will do as much of the work from the east side of the structure so we that
we disturb as little of the lawn and dirt as possible. We will load the trucks while they are
parked on the asphalt east of the house.
The Lube Shop building would be removed after the house. We will remove all the wood and
un-useable materials first,then the concrete foundation and slabs in the building area. Once this
is done we can shape this area into a settling basin area, and then start removing the concrete
and asphalt south, west, and north of this building. We will perform the work in such a manner
that we can keep our trucks on a hard surface at all times.
Since the Tire Shop building is separated from the lube building and the large asphalt/concrete
areas, it could be removed before we remove the asphalt/concrete around the Lube Shop
building. This would depend on the availability of the right manpower and how much of the
building we decide to deconstruct.

To: Dale Herrigstad
From: Jeff Miller, Assistant City Engineer
Subject: Zap Prolube Parking, 1014 26th Street
Dale,
I have reviewed your concerns over the requirement to provide in-basin
treatment for storm water run-off based upon our conversation on Nov 22, and
Kim's comments of Nov 21. Per section 10 of ordinance 2441 Drainage
Requirements, the official can require other appropriate BMP's to mitigate effects
of storm water. By the nature of the work performed at Zap Prolube, there is an
increased risk of illicit discharge and greater measures must be taken to mitigate
this increased risk. Therefore Kim's comment of"Provide in-basin treatment for
storm water run-off. Check DOE site for suitable treatment alternatives to
bioswale. Provide detail and maintenance plan for treatment BMP," still stands.
As for her other comments, you showed the accessible space on the revised
plans, you indicated all the existing parking, you indicated that no off street
parking was being provided in the alley therefore you would not be required to
construct the off street sidewalk as commented on, and you indicated the
sanitary sewer line in the alley. So with the exception of in-basin treatment, you
have met Engineering's review comments.
Therefore, please submit the revised storm water treatment for review to the City
of Anacortes.
Sincerely,
CITY OF ANACORTES

To: Dale Herrigstad
From: Kim McKinnon, EDS Project Manager
Subject: Zap Prolube Parking, 1014 26th Street
Dale,
I have reviewed the drawings presented 11/12/02 and have the following
comments.
1. One (1) van accessible parking space for less than 25 total parking ✓
spaces to meet ADA requirements.
2. Plans do not show all of existing parking. Please indicate all existing✓
parking on plans.
3. Per Anacortes Municipal Code (AMC) 17.46.040, when off street Cie
is provided in the rear of the building and there is a driveway alongside
the building, then need 3' minimum sidewalk adjoining building, curbed or
raised 6" from driveway surface. —existing concrete pad can serve as
sidewalk but need to provide 6" curb if drive is level with pad.
4. Provide in-basin treatment for stormwater run-off. Check DOE site for✓
suitable treatment alternatives to bioswale. Provide detail and
maintenance plan for treatment BMP.
a. www.ecy.wa.qov/proqrams/wq/stormwateS/newtech/index.html
5. Show existing sanitary sewer line in 16' alley. ./
Cc: Joey Goss, fax 293 3001
Joey, disregard my comments in our phone conversation regarding
asphalt thickness requirements. If road is asphalt, parking lot needs to be
asphalt. Sidewalk has to meet City standard though.

STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN
CHAPTER I-2
MINIMUM REQUIREMENTS FOR ALL NEW DEVELOPMENT AND REDEVELOPMENT
I-2.1 INTRODUCTION
The 1991 Puget Sound Water Quality Management Plan (as amended) requires all
counties and cities within the Puget Sound drainage basin to adopt ordinances to
control runoff from new development and redevelopment by July 1994. The Plan also
directs local governments to adopt stormwater programs which include minimum
requirements for new development and re-development set by the Plan and in guidance
developed by Ecology. These ordinances are to address:
. at a minimum: (1) the control of off-site water quality and quantity (as
related to quality) impacts; (2) the use of source control best management practices
and treatment beat management practices; (3) the effective treatment, using best
management practices of the storm size and frequency (design storm) as specified in
the manual for proposed development; (4) the use of infiltration, with appropriate
precautions, as the first consideration in stormwater management; (5) the protection
of stream channels and wetlands; and (6) erosion and sedimentation control for new 1
construction and re-development projects. "
This chapter has been developed in response to the direction in the Plan. The
reader is also referred to Volume II of the "Stormwater Program Guidance Manual for
the Puget Sound Basin" (hereafter referred to as the Guidance Manual) , a companion
to this technical manual, which contains a model ordinance that incorporates these
Minimum Requirements.
There are several sets of requirements for proposed new development and
redevelopment that are applied depending on the type and size of the proposed
development. In general, small sites are required to control erosion and
sedimentation from construction activities while larger sites must also provide
permanent control of stormwater runoff. Sites being redeveloped must generally meet li
the same minimum requirements as new development sites for the portion of the site
being redeveloped. In addition, redevelopment sites must provide source control
BMPs for the entire site. There may also be situations in which additional controls
are required for sites, regardless of type or size, as a result of basin plans or
special water quality concerns.
Development sites are to demonstrate compliance with the Minimum Requirements
through the preparation of Stormwater Site Plans (SSP) . The plans are described in
detail in Chapter 1-3 and in the Guidance Manual.
Two major components of these plans are an Erosion and Sediment Control (ESC) Plan
and a Permanent Stormwater Quality Control (PSQC) Plan. The ESC plan is intended to
be temporary in nature to control pollution generated during the construction phase
only, primarily erosion and sediment. The PSQC is intended to provide permanent
BMPs for the control of pollution from stormwater runoff after construction has been
completed. For small sites, this requirement is met by implementing a Small Parcel
Erosion and Sediment Control Plan.
A flow chart demonstrating these requirements is shown in Figure I-2.1.
Definitions:
New development - means the following activities: land disturbing activities,
structural development, including construction, installation or expansion of a
building or other structure; creation of impervious surfaces; Class IV -
general forest practices that are conversions from timber land to other uses;
I-2-1 FEBRUARY, 1992
rm
STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN
and subdivision, short subdi ' ' and binding site plans, as defined in
Ch.58.17.020 RCN. All other forest practices and commercial agriculture are
not considered new development.
Redevelopment - means, on an already developed site, the creation or addition
of impervious surfaces, structural development including construction,
installation or expansion of a building or other structure, and/or replacement
of impervious surface that is not part of a routine maintenance activity; and
land disturbing activities associated with structural or impervious
redevelopment.
Impervious surface - means a hard surface area which either prevents or
retards the entry of water into the soil mantle as under natural conditions
prior to development, and/or a hard surface area which causes water to run off
the surface in greater quantities or at an increased rate of flow from the
flow present under natural conditions prior to development. Common impervious
surfaces include, but are not limited to, roof tops, walkways, patios,
d ' ys, parking lots or storage , concrete or asphalt paving, gravel
roads, packed earthen materials, and oiled, macadam or other surfaces which
similarly impede the natural infiltration of stormwater. Open, uncovered
retention/detention facilities shall not be considered as impervious surfaces.
Land disturbing activity - means any activity that results in a change in the
existing soil cover (both vegetative and nonvegetative) and/or the existing
soil topography. Land disturbing activities include, but are not limited to
demolition, construction, clearing, grading, filling and excavation.
Source control BHP - A BHP that is intended to prevent pollutants from
entering stormwater. A few examples of source control BMPs are erosion
control practices, maintenance of stormwater facilities, constructing roofs
over storage and working areas, and directing wash water and similar
discharges to the sanitary sewer or a dead end sump.
Throughout this Chapter, guidance to meet the requirements of the 1991 Puget Sound
Water Quality Management Plan (as amended) is written in bold and supplemental
guidelines that serve as advice and other materials are not in bold.
I-2.2 EXEMPTIONS
• Commercial agriculture, and forest practices regulated under Title 222 WAC,
except for Class IV General forest practices that are conversions from timber
land to other uses, are exempt from the provisions of the minimum
requirements. All other new development is subject to the minimum
requirements.
I-2.3 SMALL PARCEL MINIMUM REQUIREMENTS
• The following new development shall be required to control erosion and
sediment during construction, to permanently stabilize soil exposed during
construction, to coipiy with, Small_Parcel_Requirements 1 through 4, and to
prepare a Small_Par_cel Erosion and Sediment Control Plan:
(a) Individual, detached, single family residences and duplexes.
(b) Criatido or addition of less than 5,000 square feet of impervious'
surface area.
(c) Land disturbing activities of less than one acre.
I-2-2 FEBRUARY, 1992

STORMWATER MANAGEMENT MANUAL FOR THE PUGET SOUND BASIN
Objective: The objective of this requirement is to address the cumulative effect of
sediment coming from a large number of small sites.
Supplemental Guidelines: Small parcels under 5,000 sq.ft. in size and individual,
detached, single family residences and duplexes, require the simplified erosion and
sediment controls contained in a Small Parcel Erosion and Sediment Control Plan
(SPESC) . This plan is required to fulfil the Small Parcel Minimum Requirements
outlined below in Section I-2.3. The Small Parcel BMPs found in Section II-5.10 in
Volume II are used to develop the plan. A complete description of a Small Parcel
ESC Plan can be found in Section I-3.3. The SPESC plan is meant to be temporary in
nature to deal with erosion and sediment generated during the construction phase
only. Local governments may choose to apply additional permanent, site-specific
stormwater controls to small parcels.
One method of proof of compliance could be the use of a checklist similar to that
found in Figure I-3.1. This list can be adapted as necessary to include individual
requirements of a local government.
SMALL_ PARCEL REQUIREMENT #1 Construction Access Route
• Construction vehicle access shall be, whenever possible, limited to one route.
Access points shall be stabilized with quarry spall or crushed rock to
minimize the tracking of sediment onto public roads.
Supplemental Guidelines: If sediment is inadvertently transported onto public
roads, roads shall be cleaned thoroughly at the end of the day by shoveling or
sweeping. Street washing should only be done after the bulk of the sediment has
been removed by sweeping.
SMALL PARCEL REQUIREMENT #2 'Stabilization of Denuded Areas
• Soil stabilization. All exposed and unworked soils shall be stabilized by
suitable application of BMPs, including but not limited to sod or other
vegetation, plastic covering, mulching, or application of ground base on areas
to be paved. All BMPs shall be selected, designed and maintained in
accordance with an approved manual. From October 1 through April 30, no soils
shall remain exposed for more than 2 days. From May 1 through September 30,
no soils shall remain exposed for more than 7 days.
Supplemental Guidelines: BMPs should be selected which are appropriate for the time
of the year and anticipated duration of use.
SMALL PARCEL REQUIREMENT #3 Protection of Adjacent Properties
• Adjacent properties shall be protected from sediment deposition by appropriate
use of vegetative buffer strips, sediment barriers or filters, dikes or
mulching, or by a combination of these measures and other appropriate BMPs.
SMALL PARCEL REQUIREMENT #4 + Maintenance
• All erosion and sediment control BHP' shall be regularly inspected and
maintained to ensure continued performance of their intended function.
SMALL PARCEL REQUIREMENT #5 _ 'Other BMPs
• As required by the local Plan Approval Authority, other appropriate BMP's to
mitigate the effects of increased runoff, shall be applied.

Small Parcel Minimum Requirements.
Obiective: The objective of this standard is to define the application of the
Minimum Requirements. The objective of these requirements is to reduce pollution
and minimize erosion and sedimentation from new development.
Supplemental Guidelines: Basin planning is encouraged and may be used to tailor
certain of the Minimum Requirements to a specific basin (see Minimum Requirement
#9) . The Minimum Requirements for Small Parcels are found in Section I-2.2. See
page I-2-1 for the definition of new development. See Chapter I-3 for a description
of Stormwater Site Plans.
1-2.4.2 Redevelopment
A. Where redevelopment of >_ 5,000 square feet occurs:
The new development Minimum Requirements #1 through #11, Sections I-2.5
through I-2.15, shall apply to that portion of the site that is being
redeveloped, and source control BNPs shall be applied to the entire site,
including adjoining parcels if they are part of the project. A Stormwater
Site Plan shall be prepared.
B. In addition to the above requirements, where one or sore of the following
conditions apply, a Stormwater Site Plan shall also be prepared that includes
a schedule for implementing the Minimum Requirements to the maximum extent
practicable, for the entire site, including adjoining parcels if they are part
of the project. An adopted and implemented basin plan (Minimum Requirement
#9) may be used to develop redevelopment requirements that are tailored to a
specific basin.
1. Existing sites greater than 1 acre in size with 50% or more impervious
surface.
2. Sites that discharge to a receiving water that has a documented water
quality problem. Subject to local priorities, a documented water
quality problem includes, but is not limited to water bodies:

the north as previously thought- We will grade the site such that the majority of the water
will flow back to the existing catch basins.
If there are additionalquestionss'concerns Qlease let me know.
