Preliminary Evaluation Report
Proposed Formation of a Local Improvement
District to Construct Improvements on 79th Avenue
Between Gentle Woods Drive and Bonita Road
Background
A Local Improvement District (LTD) is proposed to construct improvements on 79th Avenue
between Gentle Woods Drive and Bonita Road. This residential area consists of both a
growing number of smaller subdivided lots as well as larger lots laid out in the original
Durham Acres subdivision from 1911. As can be expected, the area density has grown
tremendously and the need to improve the roadway and infrastructure has emerged.Not all of
the residents a ce on what should be done to address the situation. For example, in the year
2000, the 79 ' Avenue Reconstruction. Project (Durham Road to Bonita Road) was a
candidate for the proposed transportation bond measure but was eliminated after certain
property owners objected to the proposed improvements voicing their desire to keep thra-
traffic off their street. The project was not constructed, and the condition of the roadway has
worsened, in an effort to pursue an improved roadway, the owners of five (5) lots on 79th
Avenue near Bonita Road have formally expressed their interest in the establishment of a
LID. These owners represent 48% of the.total area within this proposed 79th Avenue LID. As
of June 2004,the combined assessed value of these lots is$1,358,290.00.
Current Situation
Through the proposed improvements of the 79th Avenue LID, this neighborhood route will
receive several distinct enhancements to their current roadway facilities. For example, the
narrow road widths and excessive vertical curves would be reconstructed and realigned to
improve travel and visibility. The lack of existing sidewalks and bike lanes would also be
addressed. In addition, the south end of this proposed LID boundary would connect to the
terminus of an existing half-street improvement (roadway and sidewalk). In turn, 79th
Avenue would provide approximately a half-mile of roadway improvements south of Bonita
Road. In addition, several lots that are currently excluded from the public sewer would
benefit from new service laterals.
Once the improvements associated with this LID have been completed, the affected portions
of 79th Avenue will be more compliant with the City of Tigard roadway design standards. In
addition, an improved sense of visual continuity within the area will be experienced by the
residents and traveling public.
If Council moves to proceed with establishing the 79th Avenue Local Improvement District,
the following estimated time line can be expected.
• City Engineer submits Preliminary Evaluation Report(March 8,2005)
• Council directs staff to submit a resolution authorizing preparation of a Preliminary
Engineer's Report(April 12,2005)
Proposed 79th Avenue LID—Preliminary Evaluation Report

• Council Approves Preliminary Engineer's Report(June 14, 2005)
• Declaration of intention to form the LID (June 28,2005)
• District Formation (July 12,2005)
• Prepare Final.Plans/Specifications (by end of August 2005)
• Construction(September 2005 through May 2006)
• Determine/Levy Assessments by Ordinance (after completion of construction}
Alternatives Considered
• Alternative 1:
Full-Width Street improvements
79'b Avenue— 1,070 ft(approximately)
From the Leiser Park development terminus to the southern LID boundary at
the Gentle Woods development terminus.
Half-Width Street improvements
790'Avenue—510 ft(approximately)
North from the Leiser Park development terminus to Bonita Road.
The cost of this alternative is approximately$790,000.00.
• Alternative 2:
Full-Width Street improvements
79"'Avenue—530 ft(approximately)
From the Leiser Park development terminus to 530 ft south.
Half-Width Street improvements
79'h Avenue--510 ft(approximately)
North from the Leiser Park development terminus to Bonita Road.
The cost of this alternative is approximately$520,000.00.
Utilities
In terms of available storm and sewer facilities within the proposed boundary of the 79t"
Avenue LID, there is a definite potential for enhancement. As of now, 79th Avenue has
existing storm and sewer improvements from Bonita Road to the south terminus of the Leiser
Park development(520 ft south of Bonita Road).
Sewer
A feasibility study should be performed to assess the possibility of a sewer line
installation throughout the proposed limits of the LID. Alternative #1 presents the
opportunity for server improvements directed through Tax Lot 1500, owned by
Cornutt Enterprises,LLC.

Storm Drain
Within the proposed LID boundary are several existing grass or rock-lined swales that
collect/direct ranoff to an existing creek east of 791'Avenue. It is recommended that a
feasibility study be performed to determine the possibility of directing all storm
runoff into this existing creek. Again, Alternative 41 presents the opportunity for
runoff to be directed through.Tax Lot 1500, owned by Comutt Enterprises, LLC.
Water
According to the information in the City of Tigard's Magic GIS Project program,
there appears to be an 8-inch Tigard Water District Water line that runs down 79x1
Avenue. In addition, water utility features and fire hydrants were observed. However,
further investigation needs to be performed to determine the exact locations of the
water utility features throughout the proposed LID. Then, recommendations can be
made on the linaits of water utility improvements.
Gas
Further investigation and location will be needed to deteimin.e the improvements
throughout the proposed LID.
Power,Telephone, Cable and Street Lights
Currently, there are overhead lines on 79th Avenue that supply power, telephone and
cable service. it is recommended that these overhead utilities be placed underground
as part of the scope of work involved with the LID. There are currently no street
lights on 791 Avenue within the proposed boundary of the LID.
Street Design Requirements
The City of Tigard Design Standards, in conjunction with the Tigard Transportation System
Plan, call for the following on Neighborhood Routes such as 791 Avenue:
Neighborhood Route-79th Avenue
Required ROW: 50-60 ft
Pavement requirement: 28-36 ft curb-to-curb
Vehicle Lane Width: 9-10 ft
On-Street Parking: 8 ft
Sidewalks: 5 ft wide
Landscape Strips: Where Appropriate
Curb Extensions: Consider on Pedestrian Routes
Right of Way Acquisition
In order to satisfy the City of Tigard Design Standards, in conjunction with the Tigard
Transportation System Plan for Required ROW (60'), seventeen (17) lots within the
proposed LID boundary for Alternative #1 require right-of-way acquisition. The required
Proposed 79th Avenue LID—Preliminary Evaluation Report
Page 3 of 4
right-of-way acquisition is approximately 0.57 acres (or 25,022 sq ft). The required night-of-
way acquisition for Alternative#2 is approximately 0.39 acres (or 17,066 sq ft).
Issues To Be Resolved
Some of the major issues that need to be resolved for the,successful implementation of the
improvements in the proposed LID are:
• LID boundary and included property owners.
• Right of Way Acquisition of property for widening purposes.
• Sewer improvements on 79t"Avenue through the Capital Improvement Program.
• Modifying the current design to conform with current standards
• Connect to the existing curb and gutter where possible.
• Location and identification of existing utilities.
Recommendations
The LID appears feasible. To comprehensively address the deficiencies on 79th Avenue, staff
recommends the following:
• That Council direct staff to proceed with the next step in the LID process. This would
-require a resolution directing staff to proceed with the preparation of a'Preliminary
Engineer's Report. This report would examine the
• That Alternative #1 be pursued, which would establish the southerly boundary just
north of Gentle Woods Drive.
■ That a feuding source be established to prepare the Preliminary Engineer's Report.
This action could be taken in conjunction with the resolution directing staff to
proceed with the LID process.
