Sewer and storm drain manholes belonging to Vista shall be adjusted or reconstructed in accordance with the Vista Sewer System Design Standard Specifications. Manholes are either twenty- four inch ( 24") single covers or thirty-six inch ( 36") two-piece covers. Some manholes have existing cast-iron adjustment rings. For manholes that are in good condition and have no more than one cast- iron adjustment ring, the Contractor may adjust the manholes to grade using another cast-iron adjustment ring, for a maximum of two cast-iron rings. If the grout around the upper precast concrete riser rings or the frame is defective, the Contractor shall adjust the manhole to grade by removing the cover and frame, salvaging the cast-iron rings, and removing the precast concrete rings until the grout in the remaining precast concrete rings is in good condition, as determined by the Engineer. Then the Contractor shall adjust the frame and cover to grade using new precast concrete riser rings. If the cover is sitting low in the existing frame or adjustment ring, or the frame or cover is defective, the Contractor shall salvage the existing frame, cover, and rings, supplya new frame and cover, and adjust the new frame and cover to grade using precast concrete riser rings. If any manhole is defective to the extent that it requires fifteen inches or more ( 15"+) of pre - cast concrete riser rings to adjust the cover to grade, the Contractor shall reconstruct the manhole as described in the Specifications.

The Contractor shall exercise care so that surface materials such as rocks, dirt, and debris do not enter sewer lines, manholes, valve and cleanout sleeves, and other utility structures. In order to prevent contamination, Contractor shall provide a three-quarter inch ( 3/4") thick plywood platform to be placed on the concrete shelf at the bottom of sewer manholes prior to cold milling pavement work.

The shape of this platform shall conform to the circumference of the inside wall at the shelf elevation.

After the manhole had been adjusted, the material accumulated on the plywood shelf along with the plywood shelf shall be removed from the manhole and disposed of in accordance with Section 401 REMOVAL.") The Contractor shall remove all debris from the interior of manholes, valve covers, and cleanouts and shall clean all foreign material from the top of the frames and covers.

Because VID water valve cover and CP Test Station cover adjustments in paved areas must be done as the paving operation proceeds, VID typically has a crew working at the same time the Contractor is performing the paving operations. If VID is not able to perform the work due to an unforeseen circumstance, the Contractor shall adjust those facilities to grade on behalf of VID as the paving work is being done. Because the quantity of VID covers to be adjusted depends on the availability of VID crews to perform the work, the quantity in the Bid is a rough estimate for bidding purposes only. Stipulated unit prices may be included in the Bid to eliminate for all bidders the risk of including prices for those items of work in the bid and not getting the work.

Within five ( 5) Working Days of placing the asphalt concrete, the Contractor shall complete the adjustment of the manholes and miscellaneous utility frames and covers to grade. Immediately after the overlay operation, the Contractor shall mark all manhole and miscellaneous utility frames and cover locations with paint for ease of locating them in case of an emergency.

The tops of reset manholes and miscellaneous utility frames and covers shall meet the smoothness requirements as specified in Subsection 302-5.12 (" Smoothness.") and be reconstructed per the City of Vista Standard Drawing SWR-33 (" SEWER MANHOLE RECONSTRUCTION"). 157

STORMWATER MANAGEMENT PERMIT

INSTRUCTIONS
To accompany all grading and/or building permit application(s).

In order to comply with the federal Clean Water Act, the state Water Code and City Ordinances, the City of Vista requires that property owners and/or contractors complete a Stormwater Management Permit prior to issuance of any grading and/or building permit(s). The purpose of a Stormwater Management Permits to document Best Management Practices BMPs) that will be implemented to prevent pollutants ( including sediment) from entering stormwater conveyances and receiving waters. The Stormwater Management Permit becomes a part of the grading and/or building permit(s) and is subject to enforcement by City of Vista Inspectors and others. Stormwater Management Permits include the elements described in the following sections:

SECTION 1: REQUIRED INFORMATION — This section is used to provide the City with basic information necessary to evaluate and prioritize project activities. Each of the items in this section must be completed, except projects with less than 1 acres of disturbed area are not required to have a Waste Discharge Identification Number ( WDID). Grading projects with a disturbed area of greater than 1 acres must also meet additional requirements from the State Water Resources Control Board ( SWRCB). Those additional requirements include filing a Notice of Intent ( NOI) and preparation of a Stormwater Pollution Prevention Plan ( SWPPP). Please note that watercourses and waterbodies include ephemeral drainages (i.e. those that are dry during part of the year).

SECTION 2: BEST MANAGEMENT PRACTICES — Best Management Practices ( BMPs) must be selected and implemented to prevent erosion and construction - related materials, sediment, wastes and spills from entering stormwater conveyance system and receiving waters.

NOTE: It is the responsibility of the property owner and/or the contractor to determine the types of BMPs that will be used, as well as the levels of application necessary to comply with the City of Vista's Stormwater and Grading Ordinances. Failure to prevent soil erosion and discharges of sediment and other pollutants from construction sites is subject to enforcement by the City, RWQCB or others.

At a minimum, the City requires that the BMPs designated as required in Table 1 ( attached) be installed and maintained for all construction projects, as applicable. Additional BMPs listed in Table 1 may also be required in correlation to a project's scope, potential for discharges and proximity to a watercourse or other receiving waters. The property owner and/or contractor must complete Table 2 ( attached) indicating which BMPs will be used.

BMP manuals can be found at the City of Vista's permit counter. These manuals include all of the referenced BMPs listed in Table 1 from the Caltrans Storm Water Quality Handbooks and the California Stormwater BMP Handbooks.

The entire manuals may also be ordered directly from the following sources:

POLYMER FIBER
Superior Asphalt Performance
ACE XP Polymer FiberTM is a true achievement in additive technology to enhance asphalt concrete performance.

ACE XP Polymer Fiber' extends pavement service life by dramatically improving the dynamic modulus of the asphalt layer and increasing the asphalt's resistance to cracking and rutting ( distresses that may cause premature failure). To create ACE XP Polymer Fiber', high -strength man-made " aromatic polyamide" or Aramid Fibers are bundled and coated with Sasobit® wax to create an asphalt concrete additive that is simple to mix with any WMA or HMA in through a drum and or batch asphalt operation. The 3 - dimensional reinforcement throughout the asphalt layer increases the asphalt's resistance to cracking, rutting, and fatigue while providing improved ESAL ( Equivalent Single Axel Load) capacity.

Aramid Fibers are used extensively in many industries and applications including ballistic protection, heat & cut protection, automotive, ropes & cables, conveyor belts, etc. However, it takes a special fiber to withstand the extreme production temperatures of asphalt concrete without changes occurring to the reinforcement properties of the fiber.

That is why ACE XP Polymer Fiber' uses aramid fibers exclusively. Aramid is a unique man-made, high -strength polymer fiber boasting high tensile strengths over 400,000 psi ( 5 x steel), a superior stress/strain relationship, and decomposition temperatures of 932°F ( well above asphalt mixing temperatures of 400°F). Both 3/4" long and 1.5" long fiber lengths are available for superior long-term performance.

How does ACE XP Polymer FiberTM reinforce asphalt concrete? As the standard dosage of ACE XP Polymer FiberTM is mixed into WMA or HMA ( 4.2 ounces of ACE FiberTM per ton of asphalt concrete), the Sasobit® wax melts at approximately 170°F, releasing millions of Aramid Fibers uniformly throughout each ton of asphalt concrete. Aramid is a unique polymer fiber that has hair - like fibrils which root tenaciously in the liquid asphalt binder and bond to small granules and aggregates. Through the combination of high tensile strength, strength at low strain, and " fiber anchoring" ACE XP Polymer FiberTM delivers reinforcement to asphalt concrete and enhances the strength and durability of the finished asphalt concrete mix.

POLYMER FIBER
Superior Asphalt Performance
ACE XP Polymer FiberTM Lab performance translate to Field performance? During summer months when asphalt pavements get hot and " soften" it is easier for wheel loads to create ruts in the surface, but not when millions of Aramid Fibers are rooted in the asphalt because they provide resistance to the " flow" of the soft binder. Likewise, in winter months when asphalt pavements are cold, and the asphalt shrinks and expands, ACE XP Polymer FiberTM provides added tensile strength to the asphalt and enhances the pavement's resistance to thermal cracking as well as fatigue cracking that tends to happen during at higher temperatures.

POLYMER FIBER
Superior Asphalt Performance
Is ACE XP Polymer FiberTM reinforced asphalt concrete easy to pave with? Absolutely! Once ACE XP Polymer FiberTM is dispersed
throughout the asphalt mix, millions of light - weight aramid fibers go to work reinforcing the asphalt mix, but they do not cause any changes to the working characteristics of asphalt mix. ACE XP Polymer FiberTM reinforced asphalt concrete goes through the paver in the exact same way, it can be raked and shoveled the in the same way and can be compacted the same way using the same equipment. All laydown procedures are seamless, making adoption of the technology easy and cost effective. Add ACE XP Polymer FiberTM to overlays and new pavements alike.

How do I assure the right amount of ACE FiberTM gets added to my asphalt? Although ACE XP Polymer Fiber TM is engineered with controlled amounts of Sasobit® Wax in order to efficiently disperse the Aramid Fiber throughout the asphalt mix, Surface Tech recognizes the importance of proper dosage and mixing of the ACE XP Polymer FiberTM during production at the asphalt plant. ACE XP Polymer FiberTM is easily included into the asphalt mixing process at both batch and drum plant facilities. A simple -to - operate Line - Vac® Compressed Air Delivery System or the Automated Micro Doser MD3+ is used to transport the appropriate amount of ACE XP Polymer FiberTM to either the mixing drum of a drum plant or the pug mill/weigh hopper of a batch plant.

Once ACE Fiber TM is fed into mixing drum, the Sasobit® wax becomes fully soluble in the liquid asphalt binder and releases millions aramid fibers to be dispersed throughout the heated aggregate and Recycled Asphalt Pavement ( RAP) prior to the injection of the liquid asphalt binder. The addition of a single dose ( 4.2 ounces per ton of asphalt) of ACE XP Polymer FiberTM does not change the asphalt volumes or require any change to the job mix formula ( JMF).

Every ACE XP Polymer FiberTM sale provides a robust QA/QC program to ensure the right amount of ACE XP Polymer FiberTM makes its way into each ton of asphalt concrete for every project. Asphalt producers may choose from the following options to perform Certified ACE XP Polymer FiberTM mixing at their plants:

FORTA-FI reinforcement fiber will be added at a rate
of one pound per ton of asphalt concrete.

A. For projects larger than 3,000 tons with daily
production quantities exceeding 1,000 tons per
day, it is recommended that fiber - reinforcement
be added using a fiber metering device ( FMD).

The FMD will be supplied by Pacific GeoSource
and will be accompanied by an experienced
technician who will set up and run the machine
for the duration of the project. If an FMD is
purchased or leased, certified personnel from
Pacific GeoSource will provide fiber feeding
training and certification for plant personnel as
needed.

Figure 1: Voyager Portable Fiber Feeder.

RTC,

1. The FMD requires a 240/480 volt electrical
hookup at the plant and should be installed and
tested prior to the start of asphalt production.

2. The FMD holds 300 pounds of fiber -
reinforcement in the storage hopper at one
time. Fiber should be loaded into the FMD in
bulk without any plastic bags. During
production, the hopper should be refilled prior
to reaching a minimum fiber quantity of 30
pounds.

3. The FMD is a weigh - in - motion drum and blower
system which utilizes highly sensitive load cells
to precisely meter and dispense the fiber. This
innovative fiber feeding system certifies the
feed rate matches the plant production rate
ensures a dosage rate of one pound per ton.

Fiber metering data is recorded and can be
downloaded from the device as required.

PACIFIC

GEOSOURCE

4. Fiber - reinforcement is fed from the FMD into
the drum via a flexible 4 - in clear hose through
the RAP port or other suitable entry point. The
fiber injection point should be after fines
collection and before the addition of liquid
asphalt, so that mixing may occur within the hot
aggregate prior to coming in contact with liquid
binder.

5. A minimum plant production temperature of
220°F is recommended.

B. For projects smaller than 3,000 tons, it is
recommended that fiber be fed manually via
one of two procedures.

One Pound Bags

1. Place individual one - pound bags onto the
recycled asphalt pavement ( RAP) belt at a rate
matching the output of the plant in tons per
hour ( TPH) per Equation 1.

Equation 1:
3600/Tons per Hour
For example, for an operation at 300 TPH, the
dosage rate is
3600/300 = 12 ( place 1 bag every 12 seconds)

2. Plastic bag will melt instantly when bag enters
