RE: Additional Traffic Forecasting, Sensitivity Testing and Operational Tasks - Measure R Program Interchanges
Dear Marissa,
As we have discussed over the past few months, we would like to obtain additional support from Fehr and Peers to continue to assist with updates to the traffic forecasting, perform sensitivity testing, and complete an operational analysis along the Avenue K corridor to identify the preferred improvements along Avenue K that are needed to accommodate future travel demand.
When the traffic corridor study was authorized, we also provided optional tasks for potential inclusion.
Now we have a better handle on our needs and would like to authorize the following additional tasks to be performed by Fehr and Peers to continue to support the program by completing sensitivity testing of various improvements to help assess priorities, needs, and phasing of future roadway improvements for the City.
The following are the proposed tasks to allow additional support by Fehr and Peers.
Sensitivity Testing Task: Continue to provide sensitivity tests as individual projects proceed through the PA&ED phases, including the various scenarios for additional forecasts for Avenue K forecasts that reflect the Avenue J/J-8 improvements as outlined in Fehr and Peers attached proposal. This task may also include the need to update future year forecasts to reflect nearby improvements influencing travel patterns at a particular interchange.
Avenue K Operations Task: Fehr and Peers will conduct a study along the Avenue K corridor. The study will include the facilities analyzed in the Avenue K TEPA document prepared for the PSR that was approved in 2015. The purpose of the corridor study will be to identify the preferred improvements along Avenue K that are needed to accommodate future ravel demand. The details of the scope of the study is included in the attached scope of work summary by Fehr and Peers.
The proposed scope and fee for the various tasks is summarized below. More detail is provided in the attached email from Fehr and Peers.
Sensitivity Testing Task $22,550
Avenue K Operations Task $13,750

Subject: Lancaster Tasks & Budget
Hi Bob,
Here is what we are currently working on for Lancaster:
- K-8 Sensitivity Testing (Can you please confirm that I'm describing this accurately?):
• Run TDF model with a partial interchange at K-8 (off-ramps only) and assume the following at J/1-8:
Full interchange at Avenue J; Close both ramps at J-8
Full interchange at Avenue J; Close SB on-ramp at J-8
• Full interchange at Avenue J; Leave both ramps open at J-8 - Additional J/J-8 Sensitivity Testing
• Additional growth in hospital district (double current development levels) with following network assumptions:
Full interchange at Avenue J; Close both ramps at J-8
• Full interchange at Avenue J; Leave both ramps open at J-8 • No changes at K/K-8
Avenue K Forecasts for PA/ED
• Norm is requesting the updated forecasts for Avenue K and I'd like to send these to him this week • How about the following assumptions for the Avenue K forecasts? • Full interchange at Avenue J
• No changes at J-8 (leave ramps as is)
• No changes at K-8 (no access as is)
• If we need to go back and update the Avenue K forecasts based on the additional sensitivity testing we can provide new forecasts at a later date
• Norm is also asking about Caltrans review/approval of the forecasts; I'll call him to get a better idea of their overall schedule for PA/ED and perhaps we can discuss the forecast review/approval process for the other interchanges
Avenue L Forecasts for PA/ED
• Provide Avenue L 2040 forecasts for PA/ED; assume CIP network improvements (initial testing of J/J-8 options showed negligible change at Ave L)
Avenue K Operations
• The prior scope for Avenue K testing is included below; perhaps we can discuss how much of this, if any, is still needed prior to the PA/ED
1 Below is a summary of work authorized to date and the additional tasks that we have discussed.
So far, we have been officially authorized for the following tasks:
Task 1:
Lancaster Model Refinements $12,000
This task included updating and recalibrating/validating the base year model.
Task 2:
• 2A. Future Traffic Forecasts $40,000
This task included the 2035 model refinements and the
development of the preliminary forecasts for the interchange TEPA documents.
Task 4:
Documentation: Model Development & Forecasting Report $8,000 This report summarizes the base year and 2035 model
refinements and was submitted in November.
Total Budget $60,000
Total Billed to Date $60,000
Two additional tasks along with the cost estimates are outlined below.
Sensitivity Testing Task:
Work Conducted to Date: We have conducted sensitivity tests for various roadway network improvements in the City of Lancaster, including Avenues J, J-8, K and K-8. We have produced daily and peak hour forecasts to summarize the changes in future travel demands under multiple improvement scenarios.
Total Budget Estimate $10,500
Total Billed to Date $3,465
Work completed in first quarter of 2016 for Ave J but not yet billed $3,500 Future Work: We are anticipating additional sensitivity testing as individual projects proceed through their PA/ED phases (this would include the additional Avenue K forecasts that reflect the J/J-8 improvements as outlined above). This task may also include the need to update future year forecasts to reflect nearby improvements $10,000 influencing travel patterns at a particular interchange. $0 Total Budget Estimate
Total Billed to Date
Avenue K Operations Task:
We will conduct a study along the Avenue K corridor. The study will include the facilities analyzed in the Avenue K TEPA document prepared for the PSR that was approved in 2015. The purpose of the $12,500 corridor study will be to identify the preferred improvements along Avenue K that are needed to accommodate future travel demand. The corridor study will contain:
* Updated Year 2040 design forecasts based on the latest version of the City of Lancaster model
• Updated Year 2040 traffic operations (delay and LOS) at each of the study intersections.
• Updated Year 2040 traffic operations at each of the study ramp/mainline facilities
We will analyze each of the improvements contained in the Avenue K PSR and assess their long-term effectiveness. For each improvement, we will provide a recommendation regarding:
1) The need for the project based on operational benefits 2) The lack of need/operational benefits
3) Potentially delaying construction until travel demand grows (i.e., project may be needed beyond 2040)
4) Other opportunities to improve operations based on
improvements being considered in the study area (e.g., widening Avenue K-8 or providing full access at the Avenue J interchange) We will submit a technical memorandum to present our findings. $33,000 (if all
Total tasks are
approved)
Please let me know if you would like to discuss further. My schedule is pretty open tomorrow if you'd like me to stop by your office.
Thank you!

RE: Drainage Master Study - Measure R Program Interchanges - Amendment Request #1 Dear Marissa,
As we have discussed over the past few months, a contract revision is required to complete the existing conditions drainage study and the optional build-out drainage study from what was previously proposed and approved. Stantec intended on utilizing available data from the City and the County.
Unfortunately the data had gaps and a full hydrologic model is needed to complete the analysis. With the additional effort required to complete the model, the City will have a Master Drainage Study based on a reliable model that will provide existing flows for the interchange teams to use.
With the completion of the existing conditions model, we also want to authorize Stantec to complete the optional build-out analysis utilizing the new hydrologic model and make refinements based on approved land use. The original assumption of being able to utilize the existing model will not yield reliable results and an additional amount is required to complete the build-out analysis using the new hydrologic model developed for existing conditions. The following is a summary of additional costs • Create new Hydrologic Master Drainage Model for existing conditions; additional $62, 924. • Create Build-out Conditions Model for an additional $13,356.
This brings the total additional scope adjustment for creating the original and build-out models to $76,280.
In addition to these two scope adjustments, we request authorization to complete the original optional build-out task totaling $42,460, which allows Stantec to develop the build-out model based on land use assumptions.
The total with the additional scope items and authorization of the optional scope is $118,560.
Please let me know if you have any questions or need any additional information.

Dear Bob,
Reference: RFQ #574-14 Measure R Program Master Drainage Study - Additional Services Request Existing Condition Drainage Analysis
In the course of performing the drainage analysis for this project, several things have come to light concerning the quantity and quality of the existing available information resulting in significant changes to our scope. The original scope of work for this project included gathering and validating existing drainage information from Caltrans, County of Los Angeles, and cities of Palmdale and Lancaster. Our scope specifically excluded development of a new hydrologic model for the project area. Due to lack of information available, a new drainage model incorporating the City of Lancaster, west of Sierra Highway, and portions of Los Angeles County to the west and City of Palmdale to the south is required. The tributary area to be modeled covers nearly 100 square miles. Specific information missing that requires this additional work include:
• Prior City model network used for 2005 Master Plan Update. • City of Palmdale and County of Los Angeles drainage model information.
There are a couple minor additional items that contribute to this additional services request, including:
• As-built drawings were not provided in a timely manner resulting in more extensive field research than originally anticipated.
• 100-year event storm flows were not part of our original scope, but were requested and included at a nominal cost.
Buildout Condition Drainage Analysis
The buildout analysis will need to review each master-planned drainage facility to determine its impact on the existing points of concentration and diversion of runoff flows. As with the Phase 1 work, the area under consideration has grown significantly beyond what was originally considered, and therefore so also has the level of effort.
Design win communty in mind
